Overexploitation does not necessarily lead to the destruction of the resource, nor is it necessarily unsustainable. However, depleting the numbers or amount of the resource can change its quality. For example, footstool palm is a wild palm tree found in Southeast Asia. Its leaves are used for thatching and food wrapping, and overharvesting has ...
Another example of a species that could currently be experiencing coextinction is the rhinoceros stomach bot fly (Gyrostigma rhinocerontis) and its host species the endangered black rhinoceros and white rhinoceros (Diceros bicornis and Ceratotherium simum). The fly's larvae mature in a rhinoceros's stomach lining, having entered the body via ...
The danger of overexploitation is that if too many of a species offspring are taken, then the species may not recover. [12] For example, overfishing of top marine predatory fish like tuna and salmon over the past century has led to a decline in fish sizes as well as fish numbers. [4] Confiscated animal pelts from the illegal wildlife trade.
Take bats, for example. It can be hard to think of them as creatures that make the world a more beautiful place. But those that migrate have a crucial role as pollinators for a huge range of ...
Overexploitation has resulted in the extinction of over 25 marine species. This includes seabirds, marine mammals, algae, and fish. [102] [108] Examples of extinct marine species include Steller's sea cow (Hydrodamalis gigas) and the Caribbean monk seal (Monachus tropicalis). Not all extinctions are because of humans.
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]Defaunation is the global, local, or functional extinction of animal populations or species from ecological communities. [4]
Most amphibian species are also threatened by native habitat loss, [41] and some species are now only breeding in modified habitat. [42] Endemic organisms with limited ranges are most affected by habitat destruction, mainly because these organisms are not found anywhere else in the world, and thus have less chance of recovering. Many endemic ...
In biology, overabundant species refers to an excessive number of individuals [1] and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
