1. The author wants to test the benefits of kin selection. In a recent study by Martin Smith & Armstrong, it states that dominant individuals can move to where there are abundant food opportunities. In addition to a study done by Armstrong et al, states that the behaviour of the subordinate is dictated by the distribution and behaviour of the dominant individual (Armstrong & Griffiths, 2002). Also, a study done by Quinn & Busack, stated that many species such as salmon, rainbow trout and Atlantic

In the past, the American River provided more that 150 miles of spawning habitat for anadromous fish like Chinook (king) salmon and steelhead trout. With the creation of the Folsom and Nimbus dam for flood control in 1970, came the decline of native salmon and steelhead populations because upstream spawning habitats were cut off or destroyed. The Nimbus Salmon and Steelhead Hatchery was created because salmon and steelhead were threatened to become extinct and people believed the population could

The local alignment results indicate that the species from the sample is from is pink salmon. According to BLAST, the top hit (and therefore the highest scoring sequence via local alignment) belonged to the COI gene of pink salmon (figure 4), and therefore it can be strongly implied that the pink salmon one can buy at the store is, in fact, pink salmon. The electropherogram (figure 3) helped confirm the sequencing results, and the electrophoresis results confirmed the validity of the PCR products

Introduction: The Bull trout (Salvelinus confluentus) in the family Salmonidae and are a char native to Washington, Oregon, Idaho, Nevada, Montana and western Canada. Compared to other salmonids, bull trout have more specific habitat requirements that appear to influence their distribution and abundance (USFWS, 2015). Bull trout were historically regarded as pests due to their voracious predatory behavior. It was thought that bull trout depleted populations of “more desirable” game fish by feeding

Determining and understanding the enzyme activity in different types of Oncorhynchus mykiss muscle (heart, white and red) by comparing rate of reaction (V) of the succinate to the substrate concentration [S] Emily Reside 0785150 Lab Section 104 January 29th 2015 Introduction Understanding the activity of enzymes in different muscle types can aid greatly in obtaining more information about other processes such as metabolism of the tissues (Anderson et al., 2012). There are

metamorphosis in July and the known period of entry into salt water is from December until June. In the ocean E. tridentatus have been documented to primarily feed on Pacific Salmon species such as Chinook (Oncorhynchus tshawytscha), Coho (Oncorhynchus kisutch), Sockeye (Oncorhynchus nerka), and Pink (Oncorhynchus gorbuscha). O. tshawytscha have endured most lamprey attacks because researchers believe that E. tridentatus attack this salmon when it is making the transition to swim back up stream to spawn. E

Permit-Exempt Wells, Impervious Surfaces, Loss of Forest Cover Fish, Passage Barriers, Development in Floodplains and Estuaries.” The endangered salmon species in the state of Washington include the Chinook (Oncorhynchus tshawytscha,) Chum (Oncorhynchus keta,) Steelhead (Oncorhynchus mykiss,) Sockeye (Oncorhynchus nerka,) and the Bullhead trout (Salvelinus confluentus.) One such attempt at saving these species before extinction is being made by allowing consumers to speak up about the importance of this topic

Olympic National Park is a diverse ecosystem with 922,651 acres of wilderness, which include 60 glaciers, 13 rivers, 57 miles of coastline, over 600 miles of hiking trails and the largest herd of Roosevelt elk (Cervus canadensis roosevelti) in America. Olympic National Park ecosystems include subalpine forest, meadows, temperate rain forest, and the Pacific coastline; making this a diverse ecosystem. Because of the variety of elevations climate will vary, during october to march temperature will

Report Comparing the Adaptations Relating to Nitrogenous Excretion across Three Taxonomic Groups All organisms produce waste nitrogen products as part of their metabolism. Nitrogen is obtained from the diet in the form of protein and nucleic acids. When a protein is ingested, the tertiary and secondary structures of the protein are denatured. The peptide bonds are also broken, separating the protein into individual amino acids, the basic structure of which is displayed in Fig. 1.1. Amino acids

organisms need to respire to survive. Respiration requires oxygen which is brought into the body during gas exchange. In gas exchange oxygen is taken from the water or air into the bloodstream and carbon dioxide is released. The Chinook Salmon or Oncorhynchus tshawytscha is one of my chosen vertebrates, the Chinook Salmon are found natively in the Pacific Ocean, they are anadromous meaning they are born in fresh water, they move gradually move to deep salt water oceans when they are young before returning
