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, static and dynamic. The static method of collection, also known as time specific, looks at existing populations and classifies age classes from samples of individuals living a population (inventories). This method also includes looking for evidence …show more content…

The biological hypothesis assumes that there should be a positive relationship between the year born and living a longer life, wherein the age at death is increasing The null hypothesis assumes that there is a relationship between birth year and living a longer life found in the pooled data of males and females sampled from Woodland Cemetery as determined by a slope of 0. The analysis shows a negative relationship between year born and the age of death. Wherein the age at death has occurred early as the years have progressed. As determined by a p-value of 0.000000000168, this result is very significant and the null hypothesis is rejected and there is a linear relationship between age at death and year born due to having a slope of 453.95. The r2 value of 0.00534 reflects a relatively low to moderate correlation between year born and age at death. These results are counterintuitive to the original hypothesis; however, the results can be explained by biological and social interactions. For example, it is possible that are behavioral and physiological traits that have inherently encouraged earlier death rates. Perhaps the changes in lifestyles after the industrial revolutions, have played a role. For example, changes in dietary patterns, increased globalization, and changes in the workplace have all lead to an increase in chronic disease that would put people at risk for an earlier

    The gametophytes used in this experiment are of C-ferns. They tend to mature and produce spores at temperature of 28oC and conditions of high humidity. The spores that germinate first are hermaphrodites. Hermaphrodites tend to produce a pheromone called antheridiogen. It is this pheromone that causes later germinating spores to become male.

  • Low Life Expectancy During The Industrial Revolution

    526 Words  | 2 Pages

    During the Industrial Revolution of the Victorian Era, life expectancy was so low due to the lack of sanitation, working conditions, and less medical knowledge that we have now. At the time, the average age people were dying was at 35 years old (Lambert). The age, however, varied depending on where one lived. Normally, people who lived in cities died at a younger age than people who live in rural areas. The class that one was in also greatly impacted a person’s life span. It mainly impacted poor working-class communities, because of the poor conditions that came with being a member of that class (Wilde).

  • Animal Overpopulation Essay

    639 Words  | 2 Pages

    Thousands of animals are put to sleep each year due to not having any available homes for them to be adopted. According to Jennifer Sexton and Tom Warhol in Domestic Animal Overpopulation, “The average female cat can produce two litters of six kittens per year, a female dog can produce one litter of six or more puppies per year, making pet overpopulation a significant problem.” Animal overpopulation is costing money and you can help the pets with spay and neutering programs. A new solution is mandatory contracts for breeders and spay and neuter programs. This paper will talk about spay and neuter programs, contracts for breeders, and why some people don’t think animal overpopulation is a problem. Thankfully there are solutions to this issue of animal overpopulation.

  • Population Ecology vs. Neoinstitutional Theory

    1875 Words  | 4 Pages

    Organization-environment relations depict certain 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 – Santa Barbara. I will further discuss each of their strengths and weaknesses in accordance to the behavior and environment of institution, faculty, staff, and its students.

    To find out the population growth of a certain area (namely my home town of Powell, Tennessee) I visited a local cemetery to record data from the headstones. The information I collected was sex and age at death. I then charted these findings to establish the number of male and female deaths during a certain century, and the average age of each at the time of death.

    Environmental, behavioral and genetic factors would impact the life span and the demography of a society in unlike ways. Physical environment which has significant role in the aging of the people is one of those factors that would function in both ways. For instance, if an environment demands the people to be more engaged in different communities and events, the process of aging would delay; conversely, if a society’s demand from the elderly is too little, they would stay at home and the process of aging would accelerate Morgan & Kunkel 2016:

  • Overpopulation and the Environment

    2021 Words  | 5 Pages

    Humans have greatly impacted the global environment. Throughout the course of history, human populations have rapidly increased. Especially in Africa, these numbers have reached extraordinary proportions. Out of all the continents in the world, Africa’s population is increasing the most. The type of growth here is exponential. “Overpopulation is a condition when an organisms numbers exceeds the carrying of its ecological niche.” The growth rate of a population is equal to the birth rate minus the death rate. Therefore, for overpopulation to occur, the birth rate must surpass the death rate (Wiley). The current population of Nigeria is estimated to be 155,215,573. Most of the population consists of the younger generation. More specifically, 41% of the population is between the ages of 0-14. 56% of the population is between the ages of 15-64. However, only 3.1% of the population is 65 and over. This age group represents a very small part of the population. (CIA)

  • Gender Mortality Essay

    1635 Words  | 4 Pages

    Women live longer in all developed countries and almost all developing countries. However women have higher death rates than men at some ages in South Asia. Gender differences in mortality are affected by biological factors, such as hormonal influences on behaviour, and environmental factors, such as the cultural construction of gender roles. The relationship between the two factors and their influences on gender mortality differ between developed and developing countries. In developed countries, smoking has been the leading cause of higher male mortality. Higher levels of testosterone and the socialization of gender norms

I could also examine immigration records and look into the fertility rates of immigrants coming into the U.S. and how those numbers are affected by the economy and how they affect the demography of the country as well. If I were to conduct a survey I would choose a random sampling of people within childbearing ages (from 19-39 yrs old) and ask them certain questions.

  • Ecological Hermeneutics

    4355 Words  | 9 Pages

    (18) In passing it is interesting to note that from the perspective of ecological hermeneutics, such attempts such as Julian Simon’s to discount any aspect of human life which cannot be quantitatively measured are exceedingly tenuous. As he sees it, the "simplest and most accurate measure of health is length of life, summed up as the average life expectancy." But in an effort to remain objective, Simon blatantly overlooks the possibility that life expectancy might have nothing to do with quality of life, as in the cases of terminally ill patients kept alive on respirators.

    There are various systems in handling population rates and its various issues that connect with threatening our environment. The population and environment debate will forever be a back and forth problem because there is possibly no way to completely stop carbon emissions but ease its production. To help the environment, we must incorporate all potential solutions in governing population such as family planning and governmental involvement and practice renewable resources and stop on using nonrenewable resources, as well as ways to tackle overconsumption to support our corrupting environment.
