    areas of UCSB in their entirety in which two of those theories include population ecology and neoinstitutional theory. Population ecology and neoinstitutional theory looks at UCSB in divergent perspectives: population ecology looks at UCSB as a living or dying species whereas neoinstitutional theory highlights UCSB’s importance as an establishment to its field of education. With this, I am going to compare both, population ecology and neoinstitutional theory, in relation to the University of California

  • Ecology: Population Regulation

    795 Words  | 2 Pages

    Population regulation is a basic process related to most phenomena in ecology: regulation arises as a result of potentially stabilizing density-dependent processes, even when brought about by non-equilibrium mechanisms (Murdoch, 1994). No population continues to grow indefinitely. Specifically, populations that exhibit exponential growth eventually succumb to the limitations brought about by the environment. As a population’s density changes, a naturally-occurring series of interactions which are

  • Demography Is A Discipline In Ecology: Pre-Lab Questions On Population And Population

    1114 Words  | 3 Pages

    Pre-Lab Questions 1. Demography is a discipline in Ecology that deals with population measures such as, age, size and overall structure are critical to demographic work. Demography is used to help understand a population’s growth pattern, although not all individuals are the same age and size or have the same survival and birth rates. Demography allows for greater depth and detail of a population’s structure to be characterized and analyzed. 2. There are two methods for collecting demographic data

  • White Nose Syndrome in Bats

    872 Words  | 2 Pages

    The population of bats in the United States is facing a serious threat of extinction due to the outbreak of a deadly fungus called Deomyces destructans. The fungus is nicknamed White-Nose Syndrome, after the white fungus that typically appears on the infected bats noses and wings. Other signs and symptoms of White Nose Syndrome are white fungus on the ears and tail as well, bats flying during the day in the middle of winter, bats clustered near the entrance to a hibernacle or cave, and general abnormal

In this report, I will detail Barbados’s location, history, labor relations, population size and structure, industries, plus add a little zest with the beauty of the Island. Let’s begin with the location of Barbados. Barbados is an Island of a cluster of Caribbean Islands. Its location is on the boundary of the Atlantic Ocean and the

  • A comparison between stage structured models and size structured models using Himalayan tahrs and loggerhead turtles.

    681 Words  | 2 Pages

    Introduction Environmental factors influence population growth and these factors include food availability and space to live and reproduce in (Begon et al. 2006, Caswell 1996). These all need to be accounted for when creating a population model, as they influence the amount of individuals that are present (Caswell 1996). A stage model is useful as it groups individuals into their different life history stages e.g. juveniles, yearlings and adults animals or growth stages for plants (Leslie 1948).

  • Modeling metapopulation dynamics by using deterministic patch equilibrium and stochastic metapopulation extinction models

    factors driving the continued survival of that population (Bonsall et al. 2014). This will aid in the understanding of the temporal dynamics of the population when looking at the relationship between per capita growth rate and the local density of that population (Bonsall et al. 2014). When populations are fragmented, they rely on dispersal through migration to prevent inbreeding, and run the risk of extinction if they can’t (Bicknell et al. 2014). Populations are classified as metapopulations if they

  • Hypotheses Of The Effects Of Wolf Predation

    1830 Words  | 4 Pages

    Hypotheses of the Effects of Wolf Predation Abstract: This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates. The four proposed hypotheses examined are the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. There is much research literature that discusses how these hypotheses can be used to interpret various data sets obtained from field studies

  • Childhood Mortality: Let Say Happy 5th Birthday

    reasons, a look at the causes behind childhood mortality provide useful information for the improvement and prevention of childhood mortality rates in all countries. A variety of causes contribute to the reasons of child fatality. Anywhere from high population rate and low economic stability; to get to the bottom of this worldwide epidemic I feel it necessary to explore these reasons The reasons seem almost clear why developed countries such as America don’t have as astonishing statistics. In fact the

  • Environmental Effects Of Coral Bleaching

    initially became an issue for the coral, with its effects being felt fully in 2011 and 2012. Countless factors contribute to this, most of which are caused by mankind. Increases in pollution are very clearly caused by humans and directly affect coral populations worldwide. Increased exposure to UV rays is a direct result of a thinning o-zone caused by human emissions; Ocean temperatures are rising as a result of these same emissions as well. The heat trapped in our atmosphere due to CO^2 emissions contributes

    cross-border regionalism and sustainability. The two cities on the U.S.- Mexico border that Clough-Riquelme and Bringas Rábago use as examples in their book were Tijuana and San Diego. While these two cities are drastically different in terms of population and economic power, there is a strong economic and social interdependency between the two towns. Clough-Riquelme and Bringas Rábago state that in order to end inequality and poverty, the regime of political economy needs to be altered instead of

  • Parasites and their Virulence

    2298 Words  | 5 Pages

    (1994) and Antia et al. (1993) predict the modulation of virulence in parasite-host systems by integrating evolutionary and transmissibility factors. INTRODUCTION Why do certain parasites exhibit high levels of virulence within their host populations while others exhibit low virulence? The two prime factors most frequently cited (Esch and Fernandez 1993, Toft et al. 1991) are evolutionary history and mode of transmission. Incongruently evolved parasite-host associations are characterized

  • Genetic Drift Experiment: A Experiment To Study Two Factors Of Natural Selection

    1604 Words  | 4 Pages

    one main question to answer: What effect does population size has on random mechanisms? For this question, I hypothesized that if the population is smaller, then the random mechanisms will have a greater effect on the populations. I believed that this was because basic math principles would allude to the idea that any bad random mechanism to a small population would harm a greater percent than a larger population. With a greater portion of their population gone, then the amount of turtles reproducing

  • Urban Ecology

    assumptions similar to those that govern the natural world. Specifically, this theory holds the notion that the overall structure of cities is based on the struggle for limited land use. Over time, urban ecology has evolved to include a wider spectrum where it now generally refers to a subsection of ecology that studies the interactions among human beings, plants, and animals within an urban and metropolitan area, as well as the effects that urbanization have on natural ecosystems and biodiversity within

    Introduction Social ecology is the conceptual principles for knowing the outcomes and relations of the many diverse individual and environmental factors. Social ecology is defined as the study of people within an environment, which have influence on one another. It’s believed to be the earth’s societies reflection upon itself, exploring, discovering, and considering its future (Gutkind, 1974). Factors of social ecology may include the infirmities of age, an increase of population, natural disasters

  • Compare And Contrast From Malthusian Stagnation To Modern Growth

    707 Words  | 2 Pages

    Oded Galor and David N. Weil’s work, From Malthusian Stagnation to Modern Growth describes three different regimes on society including population, GDP per capita, family, and lifespan. They are the Malthusian model, the Post Malthusian model, and the Modern Growth Era model. The first of these three was the Malthusian model, developed by Malthus in the late 18th century, the Modern Growth is what we have today, and the post Malthusian model is the transition between the two ends of the spectrum
