Population ecology

Many species of plants and animals may seem attractive, but looks can be deceiving. Various kinds of plants and animals are brought in each state intentionally or accidentally. They are introduced intentionally by people for specific purposes such as to serve as pets or to fulfill the responsibilities of native species. They could also be introduced accidentally, because of increasing trade, by ocean voyaging ships, or other means. According to the National Oceanic and Atmospheric Administration…

discusses the impact on the land, and the contradicting conceptions of ownership held by Indians' and English Colonists. Cronon also explains why the shift in dominance was important. Ecosystems are supposed to change and be able to adapt. In a way, the ecology of the area in discussion was prepared for the ambush of newcomers. When Europeans first arrived to New England in 1633, the land was abundant with wild animals, forests, fruits, and vegetables. New England was near salt water and the…

Experiment: Interspecific Competition (Buckwheat v. Oats) I. Introduction Understanding relationships between organisms is crucial to the study of ecology. Within the study of organism relationships, there exist many types of ecological competitions. The focus of our lab experiment will be on interspecific competition. Interspecific competition is best defined as the competition between individuals of different species (Brooker et al 2014). The concept of interspecific competition is…

while elaborating on the topic of biodiversity. Scientists, Flockhart et al., in their scientific journal article, “Unravelling the annual cycle in a migratory animal: breeding-season habitat loss drives population declines of monarch butterflies,” hypothesize the causes of butterfly population loss. While Wilson’s purpose is to discuss science in a narrative manner to provide reading for pleasure, Flockhart et al.’s purpose is to discuss science in an informative manner to advance scientific…

BALANCING BIODIVERSITY IN CHANGING ENVIRONMENT: IMPORTANCE AND CONSERVATION Abstract: Biodiversity is the variety and variability of living organisms, including their species richness in an environment. It is a major component of environment and useful for all living organisms including man. Biodiversity plays important role in regulation of climate. Biodiversity is a major part of life-support system. It is particularly ecological, economic, spiritual, cultural, and aesthetic importance.…

Thomas Malthus, “the power of population is indefinitely greater than the power in the earth to produce subsistence for man” (Brainyquote.com, n.d.). The historical pattern of growth of the worldwide population since our origin started out slowly. Homo sapiens began approximately 130,000 to 160,000 years ago (Annenberg Learner, 2016). In early society, diseases and climate changes kept death rates high and life expectancies were short (Annenberg Learner, 2016). Our population stabilization and…

Introduction According to Charles J. Krebs ecology is the “scientific study of the interaction between organisms and their environment that determine their distribution and abundance” (Krebs 1978). The environment is made up of different components that are classified as abiotic and biotic. Abiotic deals with nonliving and physical elements like rain, wind, soil or pollutions. Biotic are living components that include predation, parasites, and competition. Competition is an interaction between…

Sustainable development refers not only to meeting the needs of modern society but also to not compromising the opportunities of future generation to meet and sustain development needs. It can be summarized as the improvement of economic, ecological, and social factors. Sustainable development and environmental protection work hand in hand but are not the same. Environmental protection is an important aspect of sustainable development as it plays a major role in protecting the finite resources…

nests could lead to a reduction in hatchling survivorship and even extirpation. Egg predation could also decrease burrowing owl, Athene cunicularia, and Gopher tortoise, Gopherus polyphemus, populations in Cape Coral. The city is presently home to 1,000 breeding pairs of burrowing owls, hosting the largest population in the state (Bancroft 2003),…

Planet Earth is an unbelievably intricate and delicate network of interconnected systems that has slowly developed over the last 4.5 billion years or so. From the aftermath of the Big Bang this planet arose as a mass of energy and elements. From that newly born mass of energy and elements evolved structured, dynamic systems containing three states of matter, solids, liquids, and gases. The evolution of this planet continued to unfold over billions of years in such a unique way that eventually…
