Scientific Article Overview

Download this document and type your answers after each question. For each question provide a brief but complete answer to the question (you should write in complete sentences and proofread your work for spelling and grammatical errors). Note that the answer may be found in more than one place. Remember that you should write in your own words. Do not copy and paste from the original article!!!

1. Why is this research important?
This research is important because animals attain concealment when overall body color resembles their background in which they live and cryptic coloration could be attained only through optimization between the yellow to brown colored pheomelanin and gray to black colored eumelanin in the hairs, and no study has explored this yet.

2. What is the hypothesis or goal of the research?
The hypothesis or goal of the research is that spiny mice would exert relatively higher pheomelanin content on the AS than on the ES because AS habitat is dry with light yellow-brown backgrounds to increase survival fitness by reducing the potential to be detected by predators.

3. What are the major methods used?
The major methods they used were they used a total of 30 mice captured from the opposing slopes and 14 were caught from the AS including the upper, middle, and lower parts. In addition, the other 16 were caught from the ES and each of them putted in individual cages. This was to consist for all individuals to standardize sample collections for hair melanin analysis.

4. What are the major results?
The major results of the experiment was that individuals on

    Diatoms are single cellular eukaryotes that are super tiny in size. They are pretty much like photosynthetic micro-organisms, some live simple or branched and others are filamentous and others are in a gelatinous envelope or tube. All diatoms are enclosed by something that is called frustule, which is made up of 2 valves that are fitted together by a girdle, which is a connective zone.…

    Introduction: The broader context of this lab was aimed at observing animals and documenting specific animal behavior patterns. Specifically, we were trying to determine if squirrels applied snakeskin randomly to certain areas of their body or if there was a specific technique to it in relation to escaping their predators. After an animal has determined that a predator is nearby, it must then take action to avoid encountering this threat. Encounters are most easily avoided by preventing predators from detecting prey in the first instance (Rosier & Langklide, 2011), for squirrels this type of behavior is known as SSA, “snake scent application”. In this lab we wanted to study two different species of squirrels, S. beecheyi and S. variegatus, in order to evaluate if SSA can be deemed as a species specific type of behavior. My hypothesis was that squirrels applied the snake skin scent to specific parts of their body in an organized manner. The null hypothesis is that squirrels apply the snake skin scent randomly to parts of their body. My prediction of my hypothesis was that squirrels apply the snake skin scent to body parts that they find prove to be advantageous when trying to escape their predators.…

It is obvious that coloration plays an important role in animal interaction and evolution. Chapter 9 focuses on the evolution of one color: black. This Chapter highlights the evolution of black coloration in jaguars, birds, pocket mice, fruit flies, and a handful of domestic species.…

    Both the Pocket Mouse and the Peppered Moth’s environment changed in color from light to dark from a major environmental impact, causing both species to adapt. The best fit organism for the environment at the time continued to reproduce until their color changed over time, and adapted to become better camouflaged from predators. The Peppered Moth and the Pocket Mouse both carry the genetic mutations of a dark color allele in the gene pool as opposed to only a light colored allele, which is the reason natural selection was able to occur and this adaptation affected the population in that specific…
