Biogeochemical Cycles: Natural Selection And Its' Role In Biodiversity (Essay Sample)

Instructions:

Paper Write a 750- to 1,050-word paper on natural selection and its role in biodiversity. Include how biogeochemical cycles and species interactions could play a role in giving organisms a selective advantage over others. Reflect on selected articles from a magazine, a journal, or a news feature that provide an in-depth examination of the topic(s) above and have been published within the last 6 months. (You may use two or more related articles.) Each short paper must contain the following: Briefly summarize the article(s). Relate the article(s) to course topics, explain why the article(s) is of interest, indicate your agreement or disagreement, and provide reasons for your opinion. Format your paper consistent with APA guidelines (cite the article(s) used, including the author, article title, magazine title, date, and page numbers).

Natural selection and its' role in biodiversity
Natural selection either expands or decreases biodiversity. Natural selection depends on different organism traits. The science daily news explains the biodiversity of birds where non-native plants in homes endanger wildlife. Urban residents in the United States turned native plants to habitats full of non-native species (Narango & Tallamy, 2018). These non-native plants are easy to maintain and have less toxic to pests. However, the species do not promote insect existence. Insects are a source of food to birds. Therefore, the non-native plants often endanger the life of birds by limiting the number of insects.
In the United States, more than one-third of insectivorous plants wither because of lack of food availability. Non-native plants often have some chemicals in their tissues that put off indigenous insects. The non-native plants are also toxic to indigenous plants. Therefore, the insects cannot feed on any plant without developing adaptation to curb the chemical defense in plant tissues. The study also noted that most of the Americans homeowners' yards dominated by the non-native plants have fewer caterpillars and predators such as spiders (Narango & Tallamy, 2018). The situation makes it worse for birds that depend on the insects for their young ones and forces the birds to turn to less suitable prey (Narango & Tallamy, 2018). The end results indicated an increase in non-native plants in the yard with a reduced number of birds. The researchers, therefore, recommended the homeowners' to plant an oak instead of Ginkgo so as to support the growth of more caterpillar species which will lead to an increase in a number of birds. The study is significant as it explains how the non-native plants endanger the life of birds and I agree with the article.
The prairies of North America initially had large pieces of land. The pieces of land were full of towering grass that created ideal nesting and foraging habitat for grassland birds. The same pieces of land were also used for farming row crops and cattle grazing. Today, approximately one percent of the piece of land remains. The declining grassland endangers the life of birds that depended on the plants for food (Nelson, 2018). The rationale behind the recent changes is because of the tall fescue. The researchers associated the cattle forage grass, tall fescue, with nest failure in small grassbirds. Tall fescue is shorter compared to native grasses, therefore it has overtaken and covered the landscape uniformly. The tall fescue accommodates fewer insects, therefore, making food availability difficult for birds (Nelson, 2018). The situation made birds migrate from the landscape in search of feeds. The tall fescue also resulted in nest parasitism by cowbirds. Cowbirds do not build their own nest but occupy other birds nest and breed in them. When dickcissels come back to their nest they produce few eggs because of minimal accommodation space (Nelson, 2018). Therefo
