Change Jonathan L. Gelbard‚ Ph.D. Department of Environmental Science and Policy‚ University of California‚ Davis THE STRUCTURE AND FUNCTION OF the world’s grasslands makes them one of the most vulnerable to global climate change of any terrestrial ecosystem (Sala et al.‚ 2000; IPCC‚ 2001a). The low-stature of vegetation confers high light availability‚ leaving many grasslands naturally vulnerable to invasive species (Wagner‚ 1989)‚ especially following disturbance (Hobbs and Huenneke‚ 1992). A critical

Ecosystems Components SCI/256 A region that receives fewer than 10 inches of rain annually is considered a desert. This lack of precipitation loosely illustrates what encompasses the desert ecosystem. Although there are many cold deserts around the globe‚ for the purpose of analysis‚ the focus of this paper will be hot desert ecosystems. The extreme heat of the day in some deserts can reach above 120 degrees and drop down below 32 degrees (National Geographic‚ 1996-2013). These temperature extremes

In ecology‚ the competitive exclusion principle‚ sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law‚ is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other‚ leading to either the extinction

Cycles and Human Impacts The carbon cycle‚ nitrogen cycle‚ and phosphorus cycle all play a big role in our environment. They are some of the key components that are recycled to create pathways know as the biogeochemical cycles. All the chemical elements that make up living cells must be recycled continuously in order for the living components of a major ecosystem to survive. The recycling of these elements is the only possible way to maintain a dynamic system. Human impacts of these cycles
