Gammarus Setosus Experiment

594 Words3 Pages

Each ecosystem has their own biodiversity, differing themselves from other ecosystems. In our experiment we are revisiting how the intensity of light effects the movements of Gammarus setosus. From J. M. WeEsøawski, M. ZajaÎczkowski, J. Wiktor (1997) report, when there are Macrofauna taxa and Macrophytes, there would a frequent amount of Gammarus setosus. With this we can conclude that Gammarus setosus plays a large role in the food chain. By getting more information of the Gammarus setosus we able to get more information for future research into the how prey and predation with the Gammarus setosus. In addition, with more data the scientific community can make further conclusions and further prove the conclusion. The Gammarus setosus also known as an amphipod or a side swimmer and occupies a freshwater habitats throughout the northern hemisphere (Karaman and Pinkster, 1977; Barnard and Barnard, 1983). Although they occupies freshwater habitat they could also live in places with salinity such as low intertidal regions. Which they are typically found. They use loose stones and soft sediment pockets polychaetes to shelter them. In our experiment, the Gammarus setosus that will be use will be taken from Wreck Beach, in the coast of British Columbia. …show more content…

Elliot (2005) explained that the spatial distribution is linked with habitat prefaces, agitation and it is an essential part of their population dynamics. As this behaviour reflects the individuals Gammarus setosus within the population as well as demographic changes (Ander- son et al. , 1982; Taylor et al. , 1983). The more the Gammarus setosus moves without a pattern, shows how they are stress due to the fact they are trying to find a better environment they are currently in. Knowing this we are able to quantify the wellbeing of the Gammarus setosus by measuring their

Hastings Point Lab Report

1610 Words | 7 Pages

70 common limpets were identified in the 40m bracket identified as the littoral zone, between 0m to 40m. The common limpet employs a range of adaptations to survive the abiotic and biotic conditions associated with the littoral zone. Firstly, the limpet uses a structural adaptation to overcome the harsh wave action in the tidal zone, by using their radula to grip on to imperfections in the rock. Furthermore, they employ a behavioural adaptation of grinding their shells down into the rock, to further ensure they are not swept away by the tide. Additionally, the limpet utilises a behavioural adaptation regarding its tough shell and powerful radula, to defend against predators.

Daphnia Magna Lab Report

247 Words | 1 Pages

Daphnia Magna are small crustaceans that are excellent for observing the effect of depressants on their nervous system. The purpose of this specific experiment is to observe the effect of ethanol, aspirin, and caffeine on daphnia’s heart rate. Not only do these chemicals affect heart rate, but they also affect the frequency of reproduction, number of eggs produced, and body structure. Pesticides similar to these chemicals can be released into the environment and daphnia re useful in monitoring toxicity levels. The agents being tested in this experiment can be administered to determine the effects of hormones, stimulants, antidepressants, and neurotransmitters.

Isopod Lab Report

1285 Words | 6 Pages

This behavior was observed in all the three experiments and through the period of observation, isopods seemed to move to different sponges before they settled down behind one of them. The χ2 value was 0.03842932, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact significant and reliable. In Trial 2, the hypothesis was that most isopods would go to the sponge with sucrose solution and our hypothesis was proved correct through the experiment. It was observed that a majority (55%) of the isopods preferred sucrose relative to the other sources of moisture.

Chickadee Foraging Habits Lab Report

1068 Words | 5 Pages

Joshua Rabideau 11/10/2016 BIOL 380 – Lab: Monday Black-Capped Chickadee Foraging Habits There are numerous organisms and interactions occurring within any ecosystem. Many times, the interactions between organisms and habitats are based on the energy needs of the organisms. In this experiment, a null hypothesis that the Black-capped Chickadee forages on various trees at random. Upon data analysis of the gathered information, it can be determined that the Black-capped chickadee were not choosing foraging sites at random. The results of a chi square test gave a value of 19,890 which is significantly larger than the 16.812 value needed to void the null hypothesis with six degrees of freedom; the probability that this variation was due to chance is less than .01.

Introduction In nature most organisms cannot change the nature of their environment therefore they must position themselves in an environment with favorable conditions to themselves and their offspring. This behavior is called habitat selection. Many organisms will exhibit a tactic response to these environmental factors. This tactic response can be positive or in favor of a certain environment and negative or against a certain environment.

Boundary Bay Tradeoffs

439 Words | 2 Pages

Tradeoffs are a frequent occurrence in Nature. They describe the compromise between two optimal but frequently incompatible traits for an organism. Andrea Pomeroy and her team applied this concept of tradeoffs to the western sandpipers, Calidris mauri, of British Columbia Canada, with the trade off of their ability to forage for food against the costs of potential predation. The main idea examined by Pomeroy was to study the spatial usage (The measure of how intensely a site is used for foraging by the sandpipers) at Boundary Bay, to determine how the birds chose their stop over sites during migration based on the tradeoffs between food abundance and predation risks.

Loggerheads Research Paper

228 Words | 1 Pages

Loggerhead turtles are species generalists. Loggerheads compete with other carnivorous predators whose diets overlaps with theirs. For example, juvenile loggerheads and Kemp’s ridleys in waters around Long Island have substantial diet overlap. Interspecific competition also occurs for nest sites for beaches shared with other sea turtles species; however, this problem was likely greater in the past before modern turtle population declines. The diet of loggerheads includes many species that are harvested by humans and consequently decreases in food resources can result in sublethal effects in the form of decreased growth rates and reproductive output (Bjorndal 2003).

Pros And Cons Of Elliott Traps

1671 Words | 7 Pages

Discussion: Throughout the study many different species were caught and examined. For starters, the Elliot traps resulted in eleven different organisms being caught by group two throughout the weekend, all of which were Rattus fuscipes and Antechinus stuartii. These species had a very similar distribution to each other, and were well dispersed throughout the tested area. The fact that we only caught these two species could demonstrate their high population in this area.

“But most important, I suppose, my experiment has made me feel important-every atom in me, in everybody” (Zindel 109). In the book The Effect of Gamma Rays on Man-in-the-Moon Marigolds by Paul Zindel, the significant symbols is the marigolds and the gamma rays. The marigolds represent Tillie, the main character, and how her mother affects her life. Her mother, Beatrice, also is important since the gamma rays in the play represent her. These symbols help reveal the characters personalities and the theme in the work.

What Effect Do Keystone Species Have On The Community

1662 Words | 7 Pages

The rate which communities and ecosystems flow are controlled by the most abundant species, dominant species, who typically provide the major energy flow (Power et al., 1996, p.609). Dominant species may exert powerful control over the presence of other species which is caused by their competitive exclusion methods and at times predation (Krebs, 2006, p.414). But not all species have a competitive nature and predator tendencies which often leads to numerical superiority. Another concept was then developed to help describe species with lower abundance but a larger effect on their environment, the keystone species. The original criteria for a keystone species was to have a crucial presence in the maintenance, organization, and diversity of their community and to be exceptional compared to the rest of the community (Mills et al., 1993, p.219).

However, the rate at which the species were discovered became less and less. This correlates with the Species Area Relationship (SAR) theory as proposed by Arrhenius. When graphed, in both plots we notice a curve. This to correlates within the SAR theory in a small area. As we did not analyze a large area, which encompassed multiple biomes, we did not find the “s” shape graph, which is evident in figure 1 in the literature review.
