Citric Acid

Citric acid is a weak organic acid found in citrus fruits. It is a good, natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of almost all living things. It also serves as an environmentally benign cleaning agent and acts as an antioxidant.

Citric acid exists in a variety of fruits and vegetables, but it is most concentrated in lemons and limes, where it can comprise as much as 8% of the dry weight of the fruit.

Methyl Cellulose

Methylcellulose (or methyl cellulose) is a chemical compound derived from cellulose. It is a hydrophilic white powder in pure form and dissolves in cold (but not in hot) water, forming a clear viscous solution or gel. It is sold under a variety of trade names and is used as a thickener and emulsifier in various food and cosmetic products, and also as a treatment of constipation. Like cellulose, it is not digestible, not toxic, and not allergenic.

Solvents

Acetone

In chemistry, acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and β-ketopropane) is the simplest representative of the ketones.

Acetone is a colorless mobile flammable liquid with melting point at -95.4 °C and boiling point at 56.53 °C. It has a relative density of 0.819 (at 0 °C). It is readily soluble in water, ethanol, ether, etc., and itself serves as an important solvent. The most familiar household use of acetone is as the active ingredient in nail polish remover. Acetone is also used to make plastic, fibers, drugs, and other chemicals.

An important industrial use for acetone involves its reaction with phenol for the manufacture of bisphenol A. Bisphenol A is an important component of many polymers such as polycarbonates, polyurethanes and epoxy resins. Acetone is also used extensively for the safe transporting and storing of acetylene. Vessels containing a porous material are first filled with acetone followed by acetylene, which dissolves into the acetone. One liter of acetone can dissolve around 250 liters of acetylene.

Stains & Indicators

Bromothymol Blue

Bromothymol blue, also known as bromthymol blue, is a chemical indicator for weak acids and bases.

The bromothymol blue acts as a weak acid in solution and therefore can be in acid or base forms which appear yellow and blue respectively. It is green in neutral solution. Bromothymol blue is typically sold in solid form as the sodium salt of the acid indicator. It also finds occasional use in the laboratory as a biological slide stain. At this point it is already blue, and a drop or two is used on a water slide. The coverslip is placed ontop of the water droplet and the specimen in it, with the blue coloring mixed in. It is sometimes used to define cell walls or nuclei under the microscope.

Bromothymol blue is mostly used in measuring substances that would have relatively low acidic or basic levels (near a neutral pH). It's often used in pools, fish tanks, or measuring the presence of carbonic acid in a liquid.

Congo Red

Congo red (C₃₂H₂₂N₆Na₂O₆S₂) is the sodium salt of benzidinediazo-bis-1-naphtylamine-4-sulfonic acid. It is a secondary diazo dye. Congo red is water soluble, yielding a red colloidal solution; its solubility is better in organic solvents such as ethanol.

It has a strong, though apparently non-covalent affinity to cellulose fibres. However, the use of congo red in the cellulose industries (cotton textile, wood pulp & paper) has long been abandoned, mainly because of its toxicity.

Due to a color change from blue to red at pH 3.0-5.2, congo red can be used as a pH indicator. Since this color change is an approximate inverse of that of litmus, it can be used with litmus paper in a simple parlor trick: add a drop or two of congo red to both an acid solution and a base solution. Dipping red litmus paper in the red solution will turn it blue, while dipping blue litmus paper in the blue solution will turn it red.

Congo red has a propensity to aggregate in aqueous and organic solutions. The proposed mechanisms suggest hydrophobic interactions between the aromatic rings of the dye molecules, leading to a pi-pi stacking phenomenon. Although these aggregates are present under various sizes and shapes, the "ribbon-like micelles" of a few molecules seem to be the predominant form (even if the "micelle" term is not totally appropriate here). This aggregation phenomenon is more important for high congo red concentrations, at high salinity and/or low pH.

Methylene Blue

Methylene blue is an heterocyclic aromatic chemical compound with molecular formula: C₁₆H₁₈ClN₃S. It has many uses in a range of different fields, such as biology or chemistry.

At room temperature it appears as a solid, odorless, dark green powder, that yields a blue solution when dissolved in water.

Methylene blue should not be confused with methyl blue, another histology stain, or with the methyl violets often used as pH indicators.

Phenol Red

Phenol red is a pH indicator that is frequently used in cell biology laboratories. A synonym for phenol red is phenolsulfonephthalein.

Phenol red exhibits a gradual transition from yellow to red over the pH range 6.6 to 8.0. Above pH 8.1, phenol red turns a bright pink (fuschia) color.

Several indicators share a similar structure to phenol red, including bromothymol blue, thymol blue, bromocresol purple, thymolphthalein, and phenolphthalein.

Phenolphthalein

Phenolphthalein is a sensitive pH indicator with the formula C₂₀H₁₄O₄.

Often used in titrations, it turns from colorless in acidic solutions to pink in basic solutions. If the concentration of indicator is particularly strong, it can appear purple.

In strongly basic solutions, phenolphthalein's pink color undergoes a rather slow fading reaction and becomes colorless again.

What is FOSS?

The Full Option Science System is a research-based science curriculum for grades K–8 developed at the Lawrence Hall of Science, University of California at Berkeley.

FOSS is also an ongoing research project dedicated to improving the learning and teaching of science. The FOSS project began over 20 years ago during a time of growing concern that our nation was not providing young students with an adequate science education.

Don't just open books. Open minds.

The FOSS program materials are designed to meet the challenge of providing meaningful science education for all students in diverse American classrooms and to prepare them for life in the 21st century. Development of the FOSS program was, and continues to be, guided by advances in the understanding of how youngsters think and learn.

Science is an active enterprise, made active by our human capacity to think. Scientific knowledge advances when scientists observe objects and events, think about how they relate to what is known, test their ideas in logical ways, and generate explanations that integrate the new information into the established order. Thus the scientific enterprise is both what we know (content) and how we come to know it (process).

The best way for students to appreciate the scientific enterprise, learn important scientific concepts, and develop the ability to think critically is to actively construct ideas through their own inquiries, investigations, and analyses. The FOSS program was created to engage students in these processes as they explore the natural world.

Foss Environments - Kit

All living things depend on the conditions in their environment. The study of the relationships between one organism and its environment builds knowledge of all organisms. With this knowledge comes an awareness of limits. Changes in an environment can be hard on organisms.

Such knowledge is important because humans can change environments. To do so without awareness of possible consequences can lead to disasters. The Environments module consists of six investigations that introduce students to these basic concepts in environmental biology.

Anabaena

Anabaena is a genus of filamentous cyanobacteria, or blue-green algae, found as plankton. It is known for its nitrogen fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern.

They are one of four genera of cyanobacteria that produce neurotoxins, which are harmful to local wildlife, as well as farm animals and pets.

Gloeocapsa

Gloeocapsa is a genus of cyanobacteria (blue-green algae) in which a number of usually spherical cells are enclosed in a thick sheath of mucilage.

Cells form new mucilaginous sheaths and as they divide, the mucilage of the whole colony usually becomes multiply lamellate. Such sheaths within sheaths are more conspicuous in some species than in others, and those species in which the sheaths are scarcely lamellate have been separated off into a separate genus, Gloeocapsopsis.

Nostoc

Nostoc is a genus of fresh water cyanobacteria that forms spherical colonies composed of filaments of moniliform cells in a gelatinous sheath. When on the ground, a Nostoc colony is ordinarily not seen; but after a rain it swells up into a conspicuous jellylike mass, which was once thought to have fallen from the sky, whence the popular names, fallen star and star jelly. It is also called witches' butter.

It can be found on moist rocks, at the bottom of lakes and springs, and rarely in marine habitats. These bacteria sometimes contain photosynthetic pigments in their cytoplasm to perform photosynthesis. It may also grow symbiotically within the tissues of plants, such as the aquatic fern Azolla (mosquito fern) or hornworts, providing nitrogen to its host.

Diatoms

Diatoms are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although some form chains or simple colonies. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica.

These walls show a wide diversity in form, some quite beautiful and ornate, but usually consist of two symmetrical sides with a split between them, hence the group name.

Dinoflagellates

Peridinium

The Dinophyceae are the main class of dinoflagellates. They include all species where the nucleus remains a dinokaryon throughout the entire cell cycle, which is typically dominated by the haploid stage. All the "typical" dinoflagellates, such as Peridinium and Gymnodinium, belong here. Others are more unusual, including some that are colonial, amoeboid, or parasitic.

Dinoflagellates are classified by morphology. Species with a theca are divided into four orders, based on the arrangement of the armor plates:

Peridiniales - e.g. Peridinium
Gonyaulacales - e.g. Ceratium, Gonyaulax
Dinophysiales - e.g. Dinophysis
Prorocentrales - e.g. Prorocentrum

The Peridiniales are probably paraphyletic to the others, and on rRNA trees they are mixed with the species that lack thecae. The other three orders are probably monophyletic, with the Dinophysiales and Prorocentrales as close relatives, united by the presence of a saggital suture dividing the theca in two. However, on rRNA trees the Prorocentrales are split up.

Greens

Chara

The Charales (Chara) are an order of green algae, and are believed to be the closest relatives of the embryophyte plants. They are branched, multicellular green algae that grow in fresh water. They are often called stoneworts, because the plants can become encrusted in lime (calcium carbonate) after some time.

They are unique in having a whorl of small branchlets at each node in the stipe. Its antheridia and oogonia are protected by a layer of sterile cells when mature, and have the most complex structure of all green algae.

Chlorella

Chlorella is a genus of single-celled green algae, belonging to the phylum Chlorophyta. It is spherical in shape, about 2 to 10 μm in diameter, and is without flagella. Chlorella contains the green photosynthetic pigments chlorophyll-a and -b in its chloroplast. It depends on photosynthesis for growth and multiplies rapidly, requiring only carbon dioxide, water, sunlight, and a small amount of minerals.

Chlorella has been researched as a potential food because it is high in protein and other essential nutrients. When dried, it is about 45 percent protein, 20 percent fat, 20 percent carbohydrate, and 10 percent various minerals and vitamins. However, because it is a single-celled alga, harvest had posed practical difficulties for its large-scale use as a food source. Methods of mass production are now being used to cultivate it in large artificial circular ponds.

Closterium

Closterium cells are crescent-shaped or elongate and lack spines. Some are quite straight and needle-like, while others are much broader with curved ends. The ends of the cell are usually tapered and may be pointed or rounded. Each semicell has a single axial, ridged chloroplast with at least one pyrenoid. Occasionally there are two chloroplasts per semicell. The nucleus is located in the center of the cell between the chloroplasts.

Terminal vacuoles at the cell tips hold vibrating crystals of barium or calcium sulfate, the function of which are unknown. Brownian motion causes these microscopic particles to move erratically due to the impacts of collisions with the surrounding liquid molecules in which they are suspended.

Micrasterias

Micrasterias is a genus whose members are considered placoderm desmids, those that feature a cell wall composed of two sections that attach in the mid-region. This type of desmid is also characteristically furnished with pores, spines, granules, or other protuberances.

Contrariwise, saccoderm desmids typically possess a smooth, unornamented cell wall that consists of a single piece. As placoderm desmids, the more than 40 known species of Micrasterias exhibit a substantial amount of diversity in the adornment of their lobed, disclike shapes, and many are among the most picturesque microscopic life forms in the world. Most often found in acidic waters and bogs, the organisms may grow between 80 to 200 micrometers in diameter.

Nitella

Nitellas are bright green algae that often are mistaken for higher plants because they appear to have leaves and stems. These long, slender, delicate, smooth-textured algae lie on the bottom of a lake or pond and are seldom found in the water column. Whorls of forked branches are attached at regularly spaced intervals along the "stems". Nitellas sometime grow together with muskgrasses (Chara spp.), another plant-like algae, to form underwater meadows.

Oedogonium

Oedogonium is a genus of filamentous green algae. Filamentous means the all the cells are in the same plane. Reproduces in 2 ways- sexually and asexually. Reproduces sexually through syngamy.

The anthridia which produces sperm and the oogonium which produces the egg, release the sperm and egg. The egg and sperm then fuse and form a zygote (2n). The zygote then produces the filamentous green algae which is haploid (1n). The oedogonium can also produce asexually through zoospores. These separate from the parent plant through the zoosporangium and continue to divide producing the filamentous green algae. Oedogium is usually freefloating when mature though it can be attached to plants. Lives in quiet, fresh water.

Pandorina

Pandorina is a genus of green alga composed of 8, 16, or sometimes 32 cells, held together at their bases to form a globular colony surrounded by mucilage. The cells are ovoid or slightly narrowed at one end to appear keystone- or pear-shaped. Each cell has two flagella with two contractile vacuoles at their base, an eyespot, and a large cup-shaped chloroplast with at least one pyrenoid.

The colonies coordinate their flagellar movement to create a rolling, swimming motion. Pandorina shows the beginnings of the colony polarity and differentiation seen in Volvox since the anterior cells have larger eyespots. Molecular sequencing has shown that pandorina is monophyletic.

Protoccocus

The structure of the single-celled alga Protococcus is similar in some ways to a plant cell. Algal cells, like those in plants, have a nucleus and a stiff cell wall made of cellulose. Floating in the cell's cytoplasm is a chloroplast, which contains chlorophyll. The chlorophyll uses energy from sunlight to make food from carbon dioxide and water. Colonies of these algae cells form green scum on ponds and moist rocks.

Spirogyra

Spirogyra is a genus of filamentous green alga of the order Zygnematales. It is commonly found in freshwater areas. Spirogyra is a photosynthetic, eukaryotic cell. Spirals of chloroplast surround the vacuole, within which the nucleus is supported by cytoplasmic strands.

In a remarkable example of conjugation, Spirogyra reproduces sexually by exchanging DNA between cells. Certain filaments in a loose parallel bundle of Spirogyra assume the female role, and others the male. The cells of adjacent filaments develop tubular extensions which grow towards one another and eventually fuse to form a continuous tube between the cells. Meanwhile the contents of each cell have formed a round sphere. The spheres from the male filament squeeze their way down the connecting tubes to fuse with a sphere of the female cell in the other filament. The result of this sexual union is the formation of a zygote (zygospore) within the chambers of the female filament. After a dormant period, the zygotes undergo meiosis and germinate, resulting in new filaments.

Volvox

Volvox is one of the best-known genera of green algae (chlorophytes) and is the most developed in a series of genera that form spherical colonies. Each Volvox is compsed of numerous biflagellate cells similar to Chlamydomonas, on the order of 1000 in total, interconnected and arranged in a hollow sphere (coenobium). The cells swim in coordinated fashion, with a distinct anterior and posterior - or since Volvox resembles a little planet, a 'north and south' pole. The cells have eyespots, more developed near the anterior, which enables the colony to swim towards light.

An asexual colony includes both somatic or vegetative cells, which do not reproduce, and gonidia near the posterior, which produce new colonies through repeated division. These daughter colonies are initially held within the parent and have their flagella directed inwards. Later, the parent disintegrates and the daughters invert. In sexual reproduction two types of gametes are produced. Male colonies release numerous microgametes or sperm, while in female colonies single cells enlarge to become oogametes or eggs.

Yellow Greens

Vaucheria

Vaucheria is a member of the Xanthophyceae (yellow-green algae) and is a very common alga and mostly of freshwater origin, but some are marine, and it can usually be found spread out along the mud like a carpet of green felt. There are about 70 species of this TribophyceaeThis particular species was discovered floating in the still part of a small stream in a huge mass and shaded from the sun by over hanging trees. A small amount was duly collected in a small laboratory container and taken home for further study. Great care must be taken with this alga, especially when trying to tease the filaments out to make a specimen for viewing under the microscope, they tend to tear easily.

Live Bacteria & Fungi Specimens

Bacteria

Bacteria (singular: bacterium) are a major group of living organisms. The term "bacteria" has variously applied to all prokaryotes or to a major group of them, otherwise called the eubacteria, depending on ideas about their relationships. Here, bacteria is used specifically to refer to the eubacteria. Another major group of bacteria (used in the broadest, non-taxonomic sense) are the Archaea. The study of bacteria is known as bacteriology, a subfield of microbiology.

Mold

Physarum

Slime molds are peculiar protists that normally take the form of amoebae, but under certain conditions develop fruiting bodies that release spores, superficially similar to the sporangia of fungi. They should not be confused with true moulds, which are actually fungi. Although cosmopolitan in distribution, they are usually small and rarely noticed. There are several different groups.

Most notable are the plasmodial slime moulds or myxogastrids (also known as acellular or true slime moulds), where the feeding stage takes the form of a giant amoeba with thousands of nuclei, called a plasmodium. It is not divided by cell membranes, but rather is enclosed by a single outer one, and is thus like a single large cell. Most are smaller than a few centimeters, but the very largest reach areas of up to two square meters, making them the largest undivided cells known. Many have bright colors such as yellow, brown, and white. Under dry conditions they may form resting structures called sclerotia. Once produced, spores release biflagellate or amoeboid gametes, which fuse pairwise to produce new plasmodia.

Amazing News
In 2006, researchers at the University of Southampton and the University of Kobe reported that they had built a six-legged robot whose movement was remotely controlled by a Physarum slime mold. The mold directed the robot into a dark corner most similar to its natural habitat.

Annelids

Earthworms

Earthworm is the common name for the larger members of the Oligochaeta (which is either a class or subclass depending on the author) in the phylum Annelida. In classical systems they were placed in the order Opisthopora, on the basis of the male pores opening to the outside of body posterior to the female pores, even though the male segments are anterior to the female. Cladistic studies have supported placing them instead in the suborder Lumbricina of the order Haplotaxida. Folk names for earthworm include "dew-worm", "night crawler" and "angleworm".

Earthworms are also called megadriles (or big worms), as opposed to the microdriles, which include the families Tubificidae, Lumbriculidae, and Enchytraeidae, among others. The megadriles are characterized by having a multilayered clitellum (which is much more obvious than the single-layered one of the microdriles), a vascular system with true capillaries, and male pores behind the female pores.

Leeches

Leeches are annelids comprising the subclass Hirudinea. There are freshwater, terrestrial and marine leeches. Like their near relatives, the Oligochaeta, they share the presence of a clitellum. Like earthworms, leeches are hermaphrodites. The medicinal leech, Hirudo medicinalis, which is native to Europe, and its congeners have been used for clinical bloodletting for thousands of years.

All leech species are carnivorous. Some are predatory, feeding on a variety of invertebrates such as worms, snails, insect larvae, crustaceans, while a very few are haemophagic parasitic blood-sucking leeches, feeding on the blood of vertebrates such as amphibians (frogs,reptiles etc.), waterfowl, fish, and mammals. Given the opportunity, they will also feed on human blood. The most important predators on leeches are fish, aquatic insects, crayfish and other leeches specialized for predation on leeches.

Tubifex Worms

Tubifex tubifex, also called the sludge worm, is a species of tubificid segmented worm that inhabits the sediments of lakes and rivers on several continents. These worms ingest sediments and gain nutrition by selectively digesting bacteria and absorbing molecules through the body wall. The worms can survive without oxygen for months, and can survive in areas so heavily polluted with organic matter that almost no other species can endure. By forming a protective cyst and lowering its metabolic rate, T. tubifex can survive drought and food shortage. Encystment may also function in dispersal of the worm.

Ecologically, it is important as a source of food for leeches, crustaceans, insects, and fishes. In a freeze dried, pelletised form, they are sold to aquarists as a form of fish-food. It is most economically important to humans as a host of Myxobolus cerebralis, which causes disease in fish stocks. No other worms are known to harbor this parasite.

T. tubifex probably includes several species, but distinguishing between them is difficult because reproductive organs, commonly used in species identification, are resorbed after mating, and because external characteristics of the worm vary with changes in salinity.

Brine Shrimp Eggs

Brine shrimp (Artemia) are a type of aquatic crustacean. They are found worldwide in saltwater, though not in oceans. Artemia is a well known genus as one variety, the Artemia nyos, a hybrid of Artemia salina, are sold as novelty gifts, most commonly under the marketing name Sea-Monkeys.

Artemia were first discovered in Lymington, England in 1755. There are mixed views on whether all brine shrimp are part of one species or whether the varieties that have been identified are properly classified as separate species.

Un-hatched brine shrimp are metabolically inactive and can remain in total stasis for several years while in dry oxygen-free conditions, even at temperatures below freezing. This characteristic is called Cryptobiosis meaning "hidden life" (also called Diapause). Once placed in water, the cyst-like eggs hatch within a few hours, and will grow to a mature length of around one centimeter on average. Brine shrimp have a biological life cycle of one year. This short life span, and other characteristics such as their ability to remain dormant for long periods, have made them invaluable in scientific research, including space experiments.

Copepods

Copepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Many species are planktonic, but more are benthic, and some continental species may live in limno-terrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds and puddles, damp moss, or water-filled recesses (phytothelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Some copepods are parasitic and attach themselves to fish, sharks, marine mammals, and many kinds of invertebrates such as molluscs, tunicates, or corals.

Copepods form a subclass belonging to the subphylum Crustacea (crustaceans). Some authors consider the copepods to be a full class. The group contains ten orders with some 14,000 described species. A scientist that studies copepods is a copepodologist.

Crayfish, sometimes called crawfish, or crawdads are freshwater crustaceans resembling small lobsters, to which they are closely related. They are found in bodies of fresh water that do not freeze to the bottom, and which have shelter against predators.

Most crayfish cannot tolerate polluted water, although some species such as the invasive Procambarus clarkii are more hardy. Some crayfish have been found living as much as 3 m (10 feet) underground.

Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They live in various aquatic environments ranging from acidic swamps to freshwater lakes, ponds, streams and rivers.

Fiddler Crabs

A fiddler crab, sometimes known as a calling crab, may be any of approximately 97 species of semi-terrestrial marine crabs within the genus Uca. Belonging to the family Ocypodidae, fiddler crabs are most closely related to the ghost crabs of the genus Ocypode.

Found in mangroves and on sandy or muddy beaches of West Africa, the Western Atlantic, Eastern Pacific and Indo-Pacific, fiddler crabs are easily recognized by their distinctively asymmetric claws. It is the males which boast an oversized claw or cheliped; it plays a role in courtship and signalling among conspecifics. The movement of the smaller claw during feeding, from the ground to the mouth, inspired the crabs' common name; to many, it appears as if the animal is playing a fiddle (the larger claw).

Gammarus (amphipods)

Gammarus setosus is a small invertebrate, approximately 1 cm in length. Its green-grey body is segmented with several jointed appendages and two larger antennae near the head. As with all members of the Malacostraca, Gammarus setosus has mouthparts located at the head segments, with their legs branching from each thoracic section, and most of their abdominal sections. Typically, Gammarus setosus is found in the benthic sub-tidal or low inter-tidal regions. They can be found in the waters off the coast of British Columbia, but have been observed in nearly all of the world's oceans.

Hermit Crabs

Hermit crabs are decapod crustaceans of the superfamily Paguroidea, distinct from the true crabs in the infra-order Brachyura. Most hermit crabs salvage empty seashells to shelter and protect their soft abdomens. There are about five hundred known species of hermit crabs in the world; although they are mostly aquatic, there are also some terrestrial species. A number of species, most notably king crabs, have abandoned seashells for a free-living life; these species have forms similar to true crabs and are known as carcinized hermit crabs.

There are several species of hermit crabs that are common in the marine aquarium trade. These omnivorous or herbivorous species are useful in the household aquarium as scavengers, eating algae and other debris.

The scarlet hermit crab, or red reef hermit crab (Paguristes cadenati), is a handsome and interesting species with a bright red body and yellow eyestalks, and stays rather small (about 2-5 cm / 1-2 inches across). Smaller species of a similar passive nature include the zebra hermit crab (brown legs with white bands), the red-tip crab and blue-legged crab.

Isopods are one of the most diverse orders of crustaceans, with many species living in all environments, and are common in shallow marine waters. Unlike most crustaceans, isopods are successful on land (suborder Oniscidea, woodlice), although their greatest diversity remains in the deep sea (suborder Asellota).

The isopods are an ancient group with fossils known from the Carboniferous (suborder Phreatoicidea, family Paleophreatoicidae) that only differ slightly from modern southern hemisphere freshwater phreatoicideans.(PICTURED TO THE RIGHT)

Ostracods

Ostracoda is a class of the Crustacea, sometimes known as the seed shrimp because of their appearance. Some 50,000 extinct and extant species have been identified, grouped into several orders.

Ostracods are small crustaceans, typically around one mm in size, but varying between 0.2 to 30 mm, laterally compressed and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper, dorsal region of the body.

Ecologically ostracods can be part of the zooplankton, or (most commonly) they are part of the benthos, living on or inside the upper layer of the sea floor. Many ostracods are also found in fresh water and some are known from humid continental forest soils.

Pillbugs

Woodlice (known locally under many names; see below) are terrestrial crustaceans with a rigid, segmented, calcareous exoskeleton and fourteen jointed limbs. They form the suborder Oniscidea within the order Isopoda, with over 3000 known species.

Woodlice need moisture because they breathe through gills, called pseudotrachea, and so are usually found in damp, dark places, such as under rocks and logs. They are usually nocturnal and are detritivores, feeding mostly on dead plant matter. They should be considered beneficial garden organisms as they recycle nutrients back into the soil. In artificial environments such as greenhouses where it can be very moist, woodlice may become abundant and damage young plants.

Common names for woodlice vary throughout the English-speaking world. They include roly-poly, pill bug (usually applied only to the genus Armadillidium), sow bug, doodle bug, carpenter (Newfoundland), woodbug, potato bug, armadillo bug, slater, ball bug, bowling ball bug, chuggy pig, hardy back, butcher boy, daddy gramfer / daddy gampfer (West Country), Granny Grey (South Wales), cheesybug (Kent), and cheeselog.

Arthropods-Insects

Ants

Ants are one of the most successful groups of insects in the animal kingdom. They are of particular interest because they are a social insect and form highly organized colonies or nests which sometimes consist of millions of individuals. Colonies of invasive ant species will sometimes work together and form super-colonies, spanning a very wide area of land. Ant colonies are sometimes described as superorganisms because they appear to operate as a single entity.

Ants have colonized almost every landmass on Earth. They can constitute up to 15% of the total animal biomass of a tropical rainforest; in the Amazon the combined weight of the ants is said to be four times larger than that of the tetrapods in the same area. As of 2006, there are 11,880 known ant species, most of which reside in hot climates.

Aphids

Aphids, also known as greenfly/blackfly or plant lice, are minute plant-feeding insects in the superfamily Aphidoidea in the homopterous division of the order Hemiptera.

About 4,000 species of aphids are known, classified in 10 families; of these, around 250 species are serious pests for agriculture and forestry as well as an annoyance for gardeners. They vary in size from 1-10 mm long.

Important natural enemies include the predatory ladybugs (Coleoptera: Coccinellidae), hoverfly larvae (Diptera: Syrphidae), and lacewings (Neuroptera: Chrysopidae), and entomopathogenic fungi like Lecanicillium lecanii and the Entomophthorales.

Aphids are distributed world-wide, but they are most common in temperate zones. It is possible for aphids to migrate great distances depending on the weather patterns (mainly passive dispersal riding on winds); for example, the lettuce aphid spreading from New Zealand to Tasmania. They have also been spread by humans transporting infested plant material.

Bess Beetles

The bess beetles or bessbugs are a family Passalidae of beetles. Nearly all of the 500-odd species are tropical; species found in North America are notable for their size, ranging from 20-43 mm, for having a single "horn" on the head, and for a form of social behavior unusual among beetles.

Bodies elongate-cylindrical and black overall; ventral surfaces may be covered with yellow setae. The head is narrower than the thorax, with antennae consisting of 10 antennomeres with a three-segment club. The elytra are elongate with parallel sides, and heavily striated.

They are subsocial (brood caring) beetles living in groups in rotting logs. They care for their young by preparing food for them and helping the larvae construct the pupal case. Both adults and larvae must consume adult feces which have been further digested by microflora for a time; an arrangement that might be described as a sort of external rumen.

In addition, they are also able to produce fourteen acoustical signals, more than many vertebrates. Adults produce the sounds by rubbing the upper surface of the abdomen against the hind wings. The larvae produce the sounds by rubbing the third leg against a striated area on the coxa of the second leg.

Centipedes (Live)

Centipedes (Class Chilopoda) are fast-moving venomous, predatory terrestrial arthropods that have long bodies and many jointed legs. Chiefly nocturnal, centipedes are found primarily in tropical climates but are also widely distributed in temperate zones. Some species are highly venomous with extremely toxic venom on their claws which can cause death in humans.

As in the closely-related millipedes, they are highly segmented (15 to 173 segments), but with only one pair of walking legs per segment. Centipedes are dorso-ventrally flattened, and are among the fastest and most agile of arthropod predators.

Crickets

Crickets, family Gryllidae (also known as "true crickets"), are insects somewhat related to grasshoppers and more closely related to katydids or bush crickets (order Orthoptera). They have somewhat flattened bodies and long antennae.

Crickets are known for their chirp (which only male crickets can do; male wings have ridges that act like a "comb and file" instrument). They chirp by rubbing their wings or legs over each other (called "stridulation"), and the song is species-specific. There are two types of cricket songs: a calling song and a courting song. The calling song attracts females and repels other males, and is fairly loud. The courting song is used when a female cricket is near, and is a very quiet song. Female crickets have a long needlelike egg-laying organ (ovipositor).

Crickets chirp at different rates depending both on their species and the temperature of their environment. Most species chirp at higher rates the higher the temperature is (approx. 60 chirps a minute at 13ºC in one common species; each species has its own rate). The relationship between temperature and the rate of chirping is known as Dolbear's Law.

Damselfly Nymphs

The Damselfly (Suborder Zygoptera) is an insect in the Order Odonata. Damselflies are similar to dragonflies, but the adults can be differentiated by the fact that the wings of most damselflies are held along the body when at rest. Damselflies are also usually smaller, and weaker fliers than dragonflies, and their eyes are separated.

Damselflies undergo incomplete metamorphosis. The female lays eggs in water, sometimes in underwater vegetation. Nymphs are carnivorous, feeding on daphnia, mosquito larvae, and other small aquatic organisms. After molting several times, the adult emerges and eats flies, mosquitoes, and other small insects.
