Invasion biology terminology

In the literature, different equations are used to calculate the energy requirement for birds (Emmans, 1974, Peguri and Coon, 1988, NRC, 1994, Sakomura et al., 1993, 2006), the factorial model has been the basis for the elaboration from these models, estimating the requirements consider the differences in weights, body composition, potential for growth and production of the animals, as well as the environment. The factorial method is based on the principle that the requirement in energy or…

According to Easthope, the concept of hybridity could be generally understood from three aspects—“biology, ethnicity and culture” (Easthope 341). Its etymology, “hybrida” that derives from biology, means a “genetic component”—two species could produce the offspring inherited some characters from, but not being any one of, both species. Its ethnical meaning refers to “an individual ‘having access to two or more ethnic identities’,” which, in Easthope’s sense, has its own limitations, for it…

As a Biochemistry and Molecular Biology major, English courses have always been viewed as inferior and subpar to STEM courses. Throughout the course, much of what was studied and the concepts that were introduced surprisingly fell in line with those of a scientist. Although science does involve quantitative analysis and calculations, it must all be translated into a dissertation explaining qualitative details. As the Winter quarter comes to a close, I have taken the time to reflect upon the…

reasons behind an animal spread are numerous. Several biological factors that influence the movement include the preference towards a resource, the presence of home range or the escape from preying. There is an extensive amount of work in mathematical biology about the effects of distinct behaviours on animal dispersal. How spatial memory influences the redistribution or the impact of the resource depletion in the population search for food and even the living circumstances for example. The…

CHARLES DARWIN. Darwin’s theory of evolution is widely looked upon, his theory has been around for a very long time and many people have looked into the theory. Charles Darwin was an english naturalist who studies of a variation of plants and animals during a five year voyage around the the world in the 19th century. Charles Darwin did explain his theory and his findings in his book called the “the origin of species”. This book was published in the 1859. Darwin's ideas caused a lot of…

Doctor in the making There I was going through the pig's trachea and went straight to his heart. Having a pig’s heart in my hands was amazing, nothing that exciting has happened to me until I decided to dissect a pig. I put the heart down and went on with my adventure, went to the pig’s stomach and poked a little hole in it, and brown liquid started to oozing out. It was probably the most disgusting but exciting thing I have seen in that class. When I found out my school offered physiology and…

Verhulst model of population dynamics: dN/dt=rN(1-N/K) in which r is the maximum growth rate of the population (N) and K is the carrying capacity of the environment, also the notion dN/dt means the derivative of N with respect to t (time) (1). The terminology of r/K-selection was first coined by ecologists Robert MacArthur and E.…

The four forces of evolution include natural selection, mutation, gene flow, and genetic drift. Natural selection is the foremost force in evolution. It states that biological traits which increase survival will become more frequent in each subsequent generation. It is the most prominent force in evolution because members of a population that inherit these traits live longer, and produce more offspring. Another force of evolution is mutation, the only cause of new genetic material. A mutation is…

Evolutionary psychology is defined “the branch of psychology that studies the ways in which adaptation and natural selection are connected with mental processes and behavior.” (Rathus, 2013) Natural selection is important because it is the ability to allow species to adapt to the current environment in order to survive and reproduce. Evolutionary psychologists study how adaption and natural selection connect with behavior and mental processes. In other words, they study changes in human…

Animal testing is used for many things. It may be used for testing medical products and just the everyday makeup that women feel the need for. Animals are also used for determining the level of toxicity of medications and checking for the safety of medications for humans. (Should) What if there was a drug that could cure cancer and we did not know if it was safe for humans to take. As mankind we would want to test the new drug on something that has a similar genetic makeup to humans just to make…
