A benefit of a specialist species is that because the species has a more clearly defined niche, this reduces competition from other species. On the other hand, generalist species, by their nature, cannot realize as much resources from one niche, but instead find resources from many. Because other species can also be generalists, there is more ...
Some plants and animals, called specialists, need specific habitats and surroundings to survive, such as the spotted owl, which lives specifically in old growth forests. Other plants and animals, called generalists, are not as particular and can survive in a range of conditions, for example the dandelion. [79]
Now it is only found in fragmented and isolated regions in the southwest of the country, as a result of widespread deforestation in the 20th century. [43] As habitat destruction of an area occurs, the species diversity offsets from a combination of habitat generalists and specialists to a population primarily consisting of generalist species. [3]
For example, the maturity of Trifolium subterraneum, a clover which was found to correlate to moisture condition; when sown in low rainfall areas of Adelaide after a few years the population would consist of genotypes that produced seeds early in the season (early genotype), however in higher rainfall areas the clover population would shift to ...
Generalist species, especially invasive ones, have been seen to benefit from this landscape change whilst specialist species are suffering. [3] For example, the alpha diversity of edge-intolerant birds in Lacandona rainforest , Mexico, is decreasing as edge effects increase.
An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. [1] [2] [3] [4]

The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...
