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 ...

One of the primary ways niche-sharing species can coexist is the competition-colonization trade-off. In other words, species that are better competitors will be specialists, whereas species that are better colonizers are more likely to be generalists. Host-parasite models are effective ways of examining this relationship, using host transfer ...
Many species fall somewhere between generalist and specialist on the generalist-specialist range. Such species generally exhibit moderate environmental specialization, being neither pure generalists nor pure specialists, resulting in fluid changes that must be evaluated when categorizing species.
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]

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. [4]
Epstein's basic argument is that focus on early specialization is unwarranted. Starting in the world of sports he contrasts Tiger Woods (who specialized early as a golfer) with Roger Federer (who played numerous sports, including tennis, before specializing only on tennis later than many of his peers) and argues that when he looks more broadly at successful people, they "seemed to have more ...
