Human behavioral ecology

Chapter Seven: The authors job as a Wildlife Conservation Department director changed his focus from extinct species to protecting the living ones. It reminded him of the species richness of the earth. Ecologists have three levels of this diversity. These measurements are the alpha, the beta and the gamma. The alpha diversity tells how many species are in an ecological community. The beta diversity compares that to the nearby communities that have different physical characteristics.…

The Debate Over Buying Locally Buying locally has becoming a debate around the world. Many advocates believe that by buying locally each consumer can do their part in saving the environment. However, there are many proponents that think other wise. It’s a matter of quality. Both side propose fantastic points around the movement of locavorism and how to conserve the environment, however, they go about it differently. The root of the debate is: does buying truly help environment and is it…

The Political Ecology of Management and Conflict in Tule Lake and Lower Klamath Lake Wildlife 'Refuges. The wildlife refuge complex in the Klamath River Basin is part of a migratory bird wetland habitat system that spans the western seaboard. Wilson (2010) refers to wetlands along the Pacific Coast as “links in a chain” leading the birds from wintering grounds to summer breeding habitats, and back again. It is estimated that three quarters of the birds traveling through this chain make a…

The text and the lecture are about reasons that caused sea otters declination. The text provide two reasons ro suppot the pollution theory of otters declining. However, the lecturer refutes this theoty and states that three reason is predator, ocra. First, the text says thata lot of sourses of chemical pollution are allonf the Alaskan coast. Thus the chemical pollution could cause immune system of sea otters and as a result to decline populatiion. However, the lecture says thatit it have not…

3. Evaluate, on the basis of research, ways in which different societies or cultures have used plants to sustain human populations while supporting environmental sustainability (e.g., sustainable agricultural practices in developing countries such as crop rotation and seed saving; traditional Aboriginal corn production practices). The agriculture and hunting of Aboriginal people focuses on taking in only what is necessary (7). Around the world millions of tons of edible food is wasted and in…

“Without sharks, you take away the apex predator of the ocean, and you destroy the entire food chain.”- Peter Benchley; Changes to living and nonliving parts of an ecosystem affect populations within an ecosystem. Life is all connected like a chain which is why there is a food chain. If you take away a piece, it all falls apart. The biggest and most dangerous living or nonliving part to take out of an ecosystem is a keystone species. The sea otter is a keystone species because of how many…

snakes. The fourth trophic level contains the tertiary consumers. They are called the tertiary consumers because they are the third level consumers, and they consumed the secondary consumers. Examples of tertiary consumers include hawks, sharks, and humans. The fifth trophic level contains apex predators. Apex predators are named as such because they are at the top of the food chain and have no predators. Examples of an apex predator include lions, crocodiles, and tigers. Decomposers sometimes…

There has long much been contention regarding whether it is only the government's responsibility to take proper action against environmental problems, or individuals and companies need to come forward with the enough initiatives for it because their activities are deemed as one of the main reasons for the environmental change. Hence, in this essay, both sides of this continuous phenomenon will be put under scrutiny, although it will be agreed with the later perspective as it has brought the…

and destructive practices that disrupt natural ecological processes. Human economies are often dependent upon the extraction, processing, and sale of those natural resources. Often, those whom profit from such actions fail to account for the damage upon habitats, and the wildlife contained within. Unsustainable practices such as forest clear cutting, large scale mining operations, and inconsiderate land use has contributed to a human-first, world-last mentality that must end immediately, lest…

Introduction Southwest Florida's ecosystem consists of warm temperate waters and a subtropical climate that attracts the majority of the generalist species. Generalist species are species that can adapt to a variety of locations without needing certain foods to eat or certain climates to survive in. Attracting generalist species that do not belong a part of Southwest Florida's ecosystem concludes in an unbalanced environmental system. My interest in this topic was the certitude that if we…
