Pond Water Argument Paper

The experiment goal was to measure the effects that different water temperatures had on the Daphnia's heart rate and the effects of epinephrine as well. Daphnia is commonly known as water flea bugs that are small aquatic crustaceans that is found plentifully in small bodies of fresh water (General Biology Study Guide and Lab Manual, 10th ed. 2007). These water bugs are good animals to use for this type of experiments because they are large enough to be seen without a microscope in light and under the microscope at twenty times magnification their internal organs can be seen straight through their body cavity. Daphnia are ectothermic creatures, meaning

13) [2.1] Is there a difference in the biology of these two phytoplankton that might be related to what is happening in this lake? (Look back at the natural history if you need to.)

This experiment was performed using the crustacean Armadillidium vulgare, also known as the pillbug. Pillbugs mate in the spring, and it takes several weeks for their fertilized eggs to hatch. After hatching the offspring spend an additional six weeks in a pouch under the female pillbug. Pillbugs eat dead and decaying organic matter, so they are often found in dark damp places. Another reason they like damp places is because they have gills that must be kept moist. The gills are located on the thorax, which is covered by large exoskeleton plates. The thorax is also where the pillbug’s seven pairs of legs are located. The pillbug also has the nickname “roly-poly,” this is because the pillbug has a defensive mechanism where it rolls into a tight ball, using the large exoskeleton plates of its thorax to protect its head and underside.

For the convenience of the students, a packet for recording the stream’s content and results was provided. On the first and second page, tables for seeing the taxa types of aquatic macroinvertebrates found were laid out, and students were to check the boxes with the names of the taxa they found in this area. Students entered the stream with a large water strain, and put dirt from the stream and carried it out of the stream to be examined. After observing several catches from the stream, the group one taxa findings included Stonefly nymph, Mayfly nymph, and Dobson fly nymph.

The macroinvertebrates graph (figure 2) represents the diversity of species inhabiting the Baldwin Swamp. In 2009 the Baldwin swamp was flourishing with a large diversity of species. A total of 33 macroinvertebrates, 8 species were recorded. At this time the baldwin swamp was healthy, abundant in life and the ecosystem and food webs were unaffected by the floods. Whereas 3 weeks after the floods swept through there were little to no range of species of macroinvertebrates. There were a recorded amount of 2 Damselfly Nymph and 1 waterboat man. A theory to why these two

Daphnia is an order of cladoceran that are a part of the genus of small crustaceans ranging from one to five millimeters in length (Campbell, 2004; Corroto 2010). Daphnia are also naturally transparent, allowing for a variety of research opportunities that are observable with current day technology. Water fleas are another name for Daphnia due to their distinct, jerky swimming patterns (Chin, 2011; Campbell, 2004). Additionally, Daphnia seem to have tufts of hair, relatively large eyes, and red “lips”. Daphnia also feature an ocellus, a light-sensing organ under the compound eye (Chin, 2011; Corotto, 2010).

At this station, we had to go into the creek, pick out rocks, and observe and identify the animal life living on that rock. Animals that live in the water need dissolved oxygen so they can breathe under the water. The more turbulent the water is, the more dissolved oxygen can be found in it. The amount of dissolved oxygen in a body of water will determine the type and number of macro-invertebrates that may live there. There are three groups of animals that you could find in the Conodoguinet Creek. Group one is called stream insects and crustaceans. These are pollution sensitive organisms, which means they cannot exist in polluted waters. Group one organisms are only found in good quality water. Some examples of these organisms are mayflies, gilled snails, water penny, or a stonefly(shown in figure 8.) The next group is the organisms that are somewhat pollution tolerant, which means they can be found in good or fair quality water. Crayfish, dragonflies, and clams are all examples of group two organisms (shown in figures 3, 6, and 9.) Group three organisms are pollution tolerant organisms. This means they can be found in any quality water. Some examples of group three organisms are pouch snails, pond snails, orb snails, and leeches. When I conducted this experiment, I found seven group one organisms, seven group two organisms, and five group three organisms. Macroinvertebrate is another word for organism.

Daphnia are small multicellular organisms, also known as the water flea (even though they are not technically a flea); they are characterized by a modified antennae used for movement, legs used for collecting food by creating a current bringing in food material to their digestive tract, they also collect food using their legs for filter feeding. (Russell, 2013) Daphnia are crustaceans, ranging around 3 mm in size, which commonly inhabit aquatic environments including lakes, ponds, and streams. (Russell, 2013) Daphnia can almost be found in any still standing water body.

Underwater grasses, or Elodea, was observed as well. This wide variety of life is a good indicator of the water’s health.

The water is a dark yellow. The plants are growing mold. 1 cricket is still alive when 2 crickets are dead and the fish is still alive.

Subclass Stichotrichia (Small & Lynn, 1985) Size, small to large; shape, often elongate, sometimes very drawn out posteriorly, in cross section round to dorsoventrally compressed; freeswimming with a few loricate forms; perilemma in some groups; pellicular alveoli weakly developed; somatic ventral ciliature as ventral cirri ranging from small and quite inconspicuous, occasionally as few as 2–3 cilia per cirrus, arranged in longitudinal, sometimes spiraled, files to a few, larger cirri in scattered groups, with in the latter case marginal files of cirri differentiated ; transverse cirri, may or may not be present; caudal cirri, may or may not be present; dorsal somatic ciliature as one to many kineties – typically three – of dikinetids without

This paper discovers the water budget for Berkeley, California in comparison to Terre Haute, Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters, where the majority of rain occurs and Terre Haute, Indiana where the rainfall is observed as consistently disseminated throughout the year evenly. This paper will also magnify geographic position, climate and elevation in contrast of the two cities that reflects the water budget outlined in Project 1: Water Balance defined in

What I found the most interesting was a small part of the kelp center that had a breeding tank of Brine shrimp. The shrimp were tiny specks and under a microscope were tiny, clear objects that floated. The center had two sets of funnels side by side, one for adult shrimp and one for hatching shrimp. They both were simultaneously working

This section provides a brief description of the biology and life history of Lithobates aerolatus (see Vanessa for a thorough review). Crawfish frogs are known to be solitary and secretive animals inhabiting crayfish burrows for most of the year (Hoffman et. al., 2010; Heemayer et. al. 2012). They have a patchy distribution in the south-central United States (Conant and Collins, 1991) and are listed as state-endangered or rare species in six of 12 states in which it occurs (IUCN REDLISt).Crawfish frogs breed from March to April in ephemeral, temporary, and seasonal wetlands usually in open grasslands but occasionally in wooded
