Human behavioral ecology

Ecology and evolution are considered sister disciplines of the life sciences. Natural selection, life history, development, adaptation, populations, and inheritance are examples of concepts that thread equally into ecological and evolutionary theory. Fresh water ecosystems is a living community of interacting organisms and their physical environment and habitat. Freshwater ecosystems are a subset of Earth's aquatic ecosystems. Some of those aquatic ecosystems include lakes, ponds, rivers,…

and other countries reveals these socio-political elements, including changes in access to resources that result from conservation enterprises. In the past, the creation of national parks in Canada sometimes involved the involuntary displacement of human communities, such as in Forillon National Park in Quebec (Kafarowski, 2003). In response to public objection to this practice, newer national parks have avoided expropriation, either by purchasing lands from willing sellers or by creating…

1. Adaptation is a noun. Also a change or the process of change of that an organism can best suit the environment lived in. A: Desert, Its hot and very dry. Less than 10 inches or rain. Quite a bit of direct sunlight. Soil is rocky and sandy which means it is unable to hold much water. Winds are usually very strong which means it drys out the plants. Plants are exposed to very hot and no water. B: Grassland, or prairie have very warm summers and chilly winters. Not much rainfall…

There are two major trophic cascades that scientist use. One is called bottom-up and the other is top-down. The controller of top-down would be the top predator or the apex predator (Wallach and O’Neill, 2009). The apex predator can also be known as the keystone species in that ecosystem. Top-down control is when the apex predator regulates the structure and population of the ecosystem (Wallach and O’Neill, 2009). The apex predators will prey on the consumers, which keeps the consumers…

Wolves are a keystone predators, they help maintain a balance in the ecosystem. They do this by hunting the weak in herds of hooved animals. Some of the animals they hunt include deer, elk, moose, and caribou, as well as beavers and rabbits. They have adapted to eating large prey. The wolves also help the herds become healthy because by eliminating the weak, they are also eliminating disease to be spread amongst the herds helping them become strong as well. When hunting, they hunt in packs of…

partly the direct result of human interactions with the park, they are as follows: threats to migratory birds, population decline in Hawaiian monk seals or green turtles, effects on various species, fish, marine invertebrates and spinner dolphins, coral damage, release of harmful pollutants, marine debris and the introduction of invasive species, recreational water/beach activities (Papahānaumokuākea Management Plan Environmental Assessment, 2008). Collectively the human threats were categorized…

The earth as an organism has been a popular topic over the last hundreds of years throughout science. However, James Lovelock’s approach of the earth was, and still is, an extremely controversial concept among scholars. He describes his theory as, “A complex entity involving the Earth’s biosphere, atmosphere, oceans, and soil; the totality constituting a feedback or cybernetic system which seeks an optimal physical and chemical environment for life on this planet” (148). In other words, the…

The formation of Mississippi Deltaic Plain (MDP) requires comprehensive work between the river and multiple coastal scales, such as temperature and space. It is very important to restore the MDP not only because it helps to understand the details that are needed to ensure the sustainability of the delta system, but it also possesses the potential to mitigate future damage from climate change to coastal ecosystem. The contribution of riverine inputs increase accretion and bulk density, benefit…

My topic is on Bhaca society and they are a compact ethnic group located in South Africa.
