The Length Weight Data Obtained For The Two Studied Species

Limpets (Patella vulgate) live in algae rich environments on rocky shores. . It has been proposed that in more sheltered areas, limpet shells will grow to be flatter with a larger diameter, while in more exposed areas of coastline, they will grow a taller and narrower shell shape. To find out whether or not the shores of Aberdeen reflected this, samples were taken from two sites (Site A and Site B) along the Aberdeen coastline that varied in their exposure to wave action. The sites were chosen to provide two sample sites with a notable difference in their environment. In the more sheltered site A, limpets were not exposed to harsh waves, while at site B, there was significantly more wave action. Quadrats were used at both sites to provide an area of sampling for the limpets and they were placed around 5 meters from the waterline. The overall results from the study showed that there is a very strong relationship between diameter and height in Limpet shells and that there was an incredibly slight difference in the relationship between the two sites.

Brooks and Dodson, the authors of the article titled “Predation, Body Size, and Composition of Plankton”, conducted research on the effect the small fish called Alosa Pseudoharengus has on an ecosystem, more specifically, different lakes in New England. Along with the data they collected on the aforementioned matter, they studied the sizes and the composition of the miniscule zooplankton inhabiting the lakes, and compared it with that of the Alosa. Their research uncovered important facts regarding water ecosystems and how they are so easily thrown off balance.

Background knowledge demands: For this book, students must know what fish and scales are. They will also need to know that fish live under the sea.

The Moths by Helena Maria Viramontes is a short story about a relationship between a teenage girl and her abuelita. Although, the title seems unfitting for a story about a loving relationship between family members the significance of the moths, in this story, has a much deeper meaning than one would think. Like many other aspects of the piece, the insects have a symbolic meaning in order to convey the author’s feelings during the time of her grandmother’s death. Throughout the story we see the use of multiple descriptions, settings, as well as dialogue in order to pass a message to the audience. The Moths is not only a story about death and brokenness, but a story about cures and peace. Upon further examination of this narrative, the story presents symbolic attributes about the main characters personalities, descriptions, and religious imagery that tell the story about a cure for brokenness, a rebirth of hope, and coming of age.

Gammarus setosus is a marine amphipod that is found in the intertidal waters of British Columbia. A study of temperature on the rate of movement of Gammarus setosus was undertaken to find whether temperature would positively or negatively affect the activity of Gammarus setosus. Specimens of Gammarus setosus was obtained and tested. 30 ppt salt water of 5°C, 23°C, and 30°C was used to perform the experiment. The specimens were allowed to acclimate for one minute. Then, the distance traveled by the specimens was collected and analyzed. A total of 13-15 replicates were tested per trial. It was found that the specimens were most active in the 20°C trial. The

The objective of the lab was to analyze the formation of pelvic structures from two populations of stickleback fish collected from two different lakes. This was done in order to formulate a question based on observable phenotypic differences in twenty specimens from two different lake populations. Careful measurements were taken including the lateral plate, pelvic girdle expression, and body depth sizes. The purpose of the research was to formulate a question and develop a hypothesis based on the variations observed between several selections of populations, in order to gain a better understanding of evolution and natural selection. The data collected was used along with information about the lakes to suggest possible environmental factors

Temperature had a direct effect on oxygen consumption of crayfish, Orconectes propinquus. Crayfish acclimated to warm temperature (20 to 25 C) had a mean mass of 8.25g +/- 1.05. Crayfish acclimated to cold temperature (3 to 5 C) had a mean mass of 10.61g +/- 0.77. Oxygen consumption rates of 30-60 minute treatments were used and there was no significant difference between the two different treatments (t=0.48, df=58, P=0.70). The data from 0-30 minutes were not used because the crayfish were disrupted by transportation and the data were not normally distributed. The Q10 value was 1.05, representing that there was full compensation for oxygen consumption for the crayfish at two different acclimated temperatures. The oxygen consumption of crayfish was not affected significantly by two different temperatures (Figure 1).

1. Based on the information in Table 2, it seems that the more dissolved oxygen in the water there is the higher the population of fish is.

“Fish Spines” by Santiago Nazarian is a simple short story that voices the insecurities of the main character, Hau, that are produced due to his job. Hau assists his parents everyday at their market stall cutting and wrapping fish. Due to the nature of his job, Hau becomes self conscious of his scent and his appearance in his personal life outside of his work place where these simple things do not matter. A girl he shares a relationship with makes him even more self conscious although she never pointed out the specific factors. The two met always after Hau was finished with work. When Hau is at the stall cutting fish, the two never really acknowledged each other's presence. Nazarian suggests an individual's confidence is a

Boats are very common on the lake, both for fishing and recreation. The lake is a popular to anglers looking for kokanee salmon (Oncorhynchus nerka) and lake trout (Salvelinus namaycush). Other fish like rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta) are also abundant in the lake. Mysis shrimp were introduced into the lake many years ago. They have had an impact on the kokanee salmon and will be analyzed in the final paper. The fishing industry provides income for the area, as well as jobs. As of recent, the populations of kokanee salmon and lake trout have been in a decline. The interaction of human management on these fish populations is needed in order to help increase these fish abundance in the lake. This issue is also linked to the management of water in the lake because water levels impact the way that fish species

Mayden (1993) used E. zonatum for comparisons in describing the new species E. alabamae. Comparing Cypress Creek to sampled E. zonatum populations in the 1993 Mayden paper show that males in Cypress Creek fell into accepted ranges for known populations but looking at the means for body measurements on average males from Cypress Creek were smaller than those measured by Mayden. Female measurements from Cypress Creek paralleled those seen in Mayden’s comparison. However, females from Bayou de Chien were larger on average than females sampled by Mayden while males were similar in measurements. Walsh and Burr (1984) noted that the maximum length of E. zonatum is usually reported as 32-38mm but lacks definition as to whether those numbers refer to standard or total length. Some variation in size for such a wide-ranging species can be caused by more southern individuals growing larger due to earlier spawning periods and longer growing seasons (Walsh and Burr, 1984). Overall, it appears that individuals found above the fall line in Cypress Creek are of similar measurements to other sampled populations of E. zonatum.

Average Yellow Perch length (TL) ranged from 87 (age 1) to 223mm (age 5), whereas, Pumpkinseed length ranged from 47mm (age 1) to 194mm (age 6) which is similar to other findings in many lakes in North America (Scott & Crossman 1998; Pierce, Rasmussen, & Leggett 1990). Pumpkinseed growth was constant for the first 4-5 years, then began to slow, whereas, growth in Yellow perch was constant for the first 2-3 years and began to slow which is similar to other studies (Copp, et al. 2004; Lauer & Doll 2007). This may be due to maturation age when energy is allocated to reproduction (Roff 1983). Purchase et al. (2005) studied life history traits of Yellow Perch in many Ontario lakes and found that Yellow Perch mature around age 2 (Purchase et al. 2005). Maturation age in Pumpkinseed is variable between lakes, but many reach maturity in their third year (Copp et al. 2004). Our results indicate that Pumpkinseed in this population may mature later since growth doesn’t appear to slow until after age 4-5 years.
