Biodiversity in Motion 1 Biodiversity in Motion Antoine Crowder Jennifer Ott ENV 300 Environmental Biology July 27, 2014 In an ever changing world it benefits all to understand those changes affecting all areas of life in a rapidly expanding planet. Biodiversity is the variation that exists in the natural world at all levels of biological organization all organisms in a defined area, all of their variations and all of their interactions with each other and with the physical environment (Bandopadhyay, Yakoob, Sunny 2010). This paper shall explain Biological evolution, competition and ecological niches, food webs, geography, human population expansion and how humans can help conservationist with the many ecosystems in the world.

The Measurement of Biodiversity is utilizes a variety of objective measures which have been established in order to empirically measure biodiversity Bandopadhyay, Yakoob, Sunny 2010). Each evaluation of biodiversity pertains to a particular use of the information. For practical conservationists, dimensions should consist of a quantification of principles that are commonly-shared among regionally impacted organisms, such as people. For others, a more financially defensible meaning should allow the guaranteeing of ongoing opportunities for both adaptation and future use by people, guaranteeing ecological durability. As a side impact, scientists claim that this evaluation is likely to be associated with the wide range of genetics. Since it cannot always be said which genetics are more likely to confirm valuable, the best option for conservationist is to guarantee the determination of as many genetics as possible. For ecologists, this latter strategy is sometimes regarded too limit as it prevents ecological sequence. Environmental Conservation Maintaining existing ecosystems benefits all life forms mainly because there is a clear relationship between the conservation of biological Diversity and the discovery of new biological resources.

The relatively small number of developed plant species currently being cultivated have been largely researched and selected for breeding. But there are many other plants presently being ignored and under-utilized food crops which have the potential to become important crops in the future. Local tribes usually use the crops and have knowledge of the uses of wild plants which makes them a good source for ideas on developing new plant products. Plants and animals are vital and undoubtedly an important part of the cultural life of humans. Human cultures have thrived and evolved over time with their environment and biological diversity has proven to impart a distinctive cultural identity to different communities. Areas needing immediate intervention and protection for conservation of biodiversity are called Biodiversity Hot Spots. The IUCN and WWF are among the leading international organizations spreading the word on protecting the globe internationally.

Biodiversity is an important tool used in promoting biodiversity conservation globally (Environmental Conservation, 2010). Biological Evolution Biological Evolution is the driving force that enriches a species self and offspring, In other words traits and genes of the strong are selected and further enhanced for future generations ensuring their equipped with the necessary strength to survive whatever climate their born into. According to the theory of evolution the process takes place because in a given population, individuals with a specific advantage over other individuals are more likely to survive, reproduce, and have offspring with similar survival skills (Edward O. Wilson). The initial step in this procedure is the development of genetic variability, Or a wide range in the inherited makeup of individuals in a community.

This happens through mutation changes in the framework or number of DNA elements in a molecule that children can inherit. Most strains result from unique changes that happen in written inherited guidelines and are passed along in reproduction. Some strains also occur from contact with exterior providers such as radioactivity, X radiation, and organic and human-made chemicals (called mutagens). Mutations can occur in any cell, but only those taking place in genes of reproductive cells are passed on to offspring (Edward O. Wilson). .

What is biodiversity and why is it important? Biodiversity refers to the variety and variability of life forms within a given ecosystem, region, or the entire planet. It encompasses all living organisms, their interactions, and their environments. Biodiversity is crucial because it supports ecosystem stability, provides resources such as food and medicine, and sustains the processes necessary for life, including nutrient cycling and pollination (Wilson, 2006). Protecting biodiversity ensures the resilience of ecosystems to withstand environmental changes and human impacts.

Various methods are employed to measure biodiversity. These include species richness, which counts the number of species in an area, and abundance, which considers the population sizes of these species. More complex indices, such as the Shannon-Weiner Index and Simpson's Diversity Index, integrate both species richness and evenness to provide a comprehensive picture of biodiversity (Magurran, 2004). Accurate measurement is fundamental for conservation efforts, enabling scientists and policymakers to identify biodiversity hotspots and prioritize areas for protection.

Biological evolution is a foundational concept explaining how species change over time due to genetic variations and natural selection. Individual organisms within a species exhibit heritable differences that influence their survival and reproductive success. Over generations, advantageous traits become more common, leading to evolutionary change (Darwin, 1859). Mutation, gene flow, genetic drift, and natural selection drive this process. Mutations introduce new genetic variation, some of which may confer survival advantages, especially in changing environments. Natural selection then favors individuals with beneficial traits, promoting adaptation and speciation (Futuyma & Kirkpatrick, 2017).

Ecological niches and competition shape community dynamics. An ecological niche describes the role an organism plays within its ecosystem, including its habitat, resource use, and interactions with other species. When niches overlap, competition occurs, which can result in competitive exclusion or resource partitioning (Tilman, 1982). These interactions influence species distribution, diversity, and evolution.

Food webs illustrate the complex feeding relationships among species, showing who eats whom. They are vital for understanding energy flow and nutrient cycling within ecosystems. Disruptions to food webs—for example, through the loss of keystone species—can cause ecological imbalances and threaten biodiversity (Pimm et al., 1995).

The geographic distribution of species and ecosystems also affects biodiversity. Factors such as climate, topography, and historical events influence the variation in species richness across regions. Biodiversity hotspots—areas with exceptionally high species richness and endemism—are critical conservation targets. The International Union for Conservation of Nature (IUCN) designates several such hotspots globally, emphasizing their importance for global biodiversity preservation (Myers et al., 2000).

Human population growth exerts profound impacts on biodiversity. Expanding populations lead to habitat destruction, pollution, overexploitation, and the introduction of invasive species. These threats accelerate species extinction rates and diminish ecosystem services. Sustainable practices and conservation efforts are vital to mitigating these impacts (Cardinale et al., 2012).

Humans can assist in conserving biodiversity through various strategies, including protected area designations, habitat restoration, sustainable resource management, and promoting awareness and education. Incorporating indigenous and local knowledge enhances conservation outcomes. International cooperation, guided by organizations like the World Wildlife Fund (WWF) and IUCN, is essential for protecting ecosystems globally (Dudley, 2008).

In conclusion, biodiversity is a complex and vital facet of life on Earth that requires continuous effort for conservation. Understanding biological evolution, ecological interactions, and human impacts enables us to better protect this invaluable resource for future generations.
