Simplified schematic of an island's fauna – all its animal species, highlighted in boxes. Fauna (pl.: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are flora and funga, respectively. Flora, fauna, funga and other forms of life are collectively referred to as biota.
At present, several countries have already imported so many exotic species, particularly agricultural and ornamental plants, that their indigenous fauna/flora may be outnumbered. For example, the introduction of kudzu from Southeast Asia to Canada and the United States has threatened biodiversity in certain areas. [196]
Flora (pl.: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring native plants. The corresponding term for animals is fauna, and for fungi, it is funga. [1] Sometimes bacteria and fungi are also referred to as flora as in the terms gut flora or skin flora for purposes of specificity.
A lion (Panthera leo).Lions are an example of charismatic megafauna, a group of wildlife species that are especially popular in human culture.. Wildlife refers to undomesticated animals and uncultivated plant species which can exist in their natural habitat, but has come to include all organisms that grow or live wild in an area without being introduced by humans. [1]
Then, Fauna included moving organisms (animals and protist as "micro-fauna") and Flora the organisms with apparent no movement (plants/fungi; and bacteria as "microflora"). The terms "microfauna" and "microflora" are common in old books, but recently they have been replaced by the more adequate term " microbiota ". [ 2 ]
The characteristic flora and fauna in the mountains tend to strongly depend on elevation, because of the change in climate. This dependency causes life zones to form: bands of similar ecosystems at similar elevations. [5]
The flora and fauna must adapt to extremely harsh conditions, however, has been able to do so successfully through evolutionary change. Many threats exist today to the tundra biome including mining, oil drilling, increased habitat loss, human habitations moving farther north, and global warming which is melting more and more permafrost and ...
Supplying water poses problems for the natural environment. Bodies of water, including lakes, ponds, and wetlands, are drained to create homes or other facilities. Water can also be redirected to address population growth or economic development, which may compete with the needs of flora and fauna.
