Human behavioral ecology

Based on the analysis of the food web, it has been determined that the pond is a healthy and stable ecosystem, although a keystone species is not present. This disproves the hypothesis formed earlier in this lab that stated, “The pond is not ecologically stable and there is no keystone species. The pond does not seem to be biodiverse, and the relative population sizes of the organisms appears to be low, based on visual observations. A keystone species also does not appear to be present, or else…

Introduction Thank you and good morning Madame speaker, The Federal government should have specific powers under the Australian constitution to legislate for the environment. This is necessary to achieve environmental protection whilst improving the environmental performance. The evolution of environmental laws has corresponded with refining of the collective environmental concerns and values. Previously in the past, the way the law has protected the environment was completely evident. The…

environment. Though, similar to other biomes, the Chaparral can be impacted by humans and environmental factors. In addition, the altering of organisms’ energy sources can negatively impact the biome’s ecosystem. It is important to have a biome where humans, plants, and animals can coexist utopically. The Chaparral biome is considered appealing to humans, hence it is a tourist attraction. To accommodate the tourist’s needs, humans are developing buildings and factories that are…

urbanization of Area 2, human impact, and nest predation. The Hardy-Weinberg principle states that the allele and genotype frequencies of a population will remain constant as long as population remains large. Thus, a change in the population may change the allele and genotype frequencies which may change the observed heterozygosity. Due to the amount of human interaction, the bottleneck effect, which occurs when the size of a population is reduced due to a natural disaster or human actions, may…

Count Them While You Can “Saving one animal won't change the world, but it will change the world for that one animal” (Unknown). This is the perspective that Jane Goodall maintained throughout the years as she observed the American Burying Beetle. Jane Goodall is a primatologist, ethologist, anthropologist, and a UN messenger of peace. She worked along chimpanzees to observe their behavior which by surprise, made a revolutionary impact on the scientific world. In Jane Goodall’s scientific essay,…

After reading “The Hidden Costs of Going Green” by Bill Carter and “For Job Market, Green Means Growth” by Brian Wingfield I have seen both sides of the situation for going green. Carter touches on the hazards that occur by turning our world into a green world (550-1). Wingfield promotes the economic boost going green would give to our world in his article (548-9). The authors’ have taken their side on the issue, but now it is my turn to determine which author has a more credible argument. When…

We love our Everglades. The Everglades a popular and beautiful place in southern Florida. Unfortunately, much of it is being destroyed and polluted. The Everglades are crucial to plants and animals including human survival. Everything interacts with one another, such as the food chain. When disrupted multiple species may become endangered. If a predators population grows too rapidly the prey will be endangered. Once the prey is gone, what will the predators eat? Sooner or later, the whole…

This case implicated a challenge brought by the Western Watersheds Project (“WWP”), in which the Bureau of Land Management (“BLM”) decided to grant a 10 -year grazing permit to LHS Spilt Rock Ranch, LLC (“Split Rock”), for four federal public land allotments in central Wyoming (“the Split Rock allotments”).1 The 102-page Environmental Assessment was published in 2009. Relying largely on the 2005 Rangeland Health Standards Assessment (RHS), it recognized significant ecological issues on the…

The broad similarity between two articles Ehlers, Worm & Reusch (2008) and Campanella et al. (2013) is that both papers emphasized the importance of the genetic diversity of Zostera marina, an ecologically important plant for coastal ecosystem to survive adverse environmental conditions arising from climate change, catastrophic events (storm, heat waves) and anthropogenic activities (pollution, eutrophication, habitat destruction etc). Ehlers et al. (2008) talked about the effects of temperature…

“9 Foot ‘Butcher Crocodile’ Likely Ruled Before Dinosaurs” These 9 foot tall beast with blade like teeth once lived in the warm and wet environs of what is now called North Carolina about 2 centuries ago.Once these crocs were called Butcher Crocodiles but now referred as Carnufex Carolinensis. These crocodiles ancestor likely walked on their hind legs, preying on armored reptiles and early mammal in it’s ecosystem. It shares some qualities with dinosaurs such as it shared some skeletal…
