Habitat loss is defined as the total destruction of natural ecosystems, an inevitable consequence of expanding human populations and human activities. Island biogeography theory offers a good explanation of why habitat loss leads to species extinction. Using oceanic islands as a model system, one of the main predictions of the theory is that larger islands

Habitat fragmentation creates small and isolated subpopulations that have fewer opportunities to find food, water, shelter, and mates and occurs due to human activities such as agriculture, deforestation, infrastructure, and road development. As governments and industries implement measures to accelerate economic growth, ecosystems that once covered large areas continue of land are being increasingly divided

One of the major consequences of ecosystem dynamics relative to human influence is biomagnification. Biomagnification is the increasing concentration of persistent and toxic substances in organisms at each successive trophic level. These are fat-soluble substances that are stored in the fat reserves of every organism. Many substances have been shown to biomagnify, including classic studies

First, it is important because it represents the almost infinite diversity of plant and animal life and the diversity of types of ecosystems on Earth that support life as we know it. It allows people to survive in conditions that would otherwise result in harsh conditions. Things that support evolution and differentiation between the different

Effects of chemical pollution There are three main routes of exposure, or ways a substance can enter your body. • Breathing (inhalation): Inhalation of chemical gases, mists or dusts in the air. • Skin or Eye Contact: Contact of chemicals with skin or eyes. They can damage the skin or be absorbed through the skin

The ocean is the largest marine biome. It is a continuous body of saltwater relatively uniform in chemical composition mineral salts and decomposed biological matter. Ocean The ocean is divided into a few zones depending on the distance reached by light in the water. Each zone has a different group of species adapted to the

Bioremediation uses living organisms to remove or minimize contaminants from a polluted site. According to the US EPA, bioremediation is the treatment that uses natural organisms to break down chemicals into less toxic or non-toxic substances. Bioremediation is used to treat human wastewater as well to remove agricultural chemicals (pesticides and fertilizers) that leach from

A biodiversity hotspot is a method of identifying regions of the world where special attention is needed to fighting against the loss of biodiversity and stimulating investments for conservation, it is rich in many rare and endemic species. The idea first came from Norman Myers in 1988. Conservation International adopted the Myers hotspots as an

A community dominated by one or two species is considered less diverse than a community in which several species have similar abundance. The Simpson’s Diversity Index is the measurement of diversity that considers the number of species present, and the relative abundance of each species. D = (n / N)2n As species richness and uniformity

Biodiversity conservation is an extraordinary challenge that must be addressed through a better understanding of biodiversity itself, changes in human behavior and beliefs, and various conservation strategies. The number of species on the planet, or in any geographical area, is the result of a balance of two evolutionary processes: speciation and extinction. When speciation rates
