Diferenzas entre revisións de «Complexo de especies»

 
[[Ficheiro:AnophelesGambiaemosquito.jpg|miniatura|O complexo do mosquito ''[[Anopheles gambiae]]'' comprende especies que son [[vector epidemiolóxico|vectores]] da [[malaria]] e outras que non.<ref name="Besansky 1994" />]]
As especies causantes de pragas e enfermidades e os seus [[vector epidemiolóxico|vectores]], teñen unha importancia directa para os humanos. Cando se descobre que son complexos de especies crípticas, a ecoloxía e virulencia de cada unha destas especies debe ser reavaliada para idear as estratexias de control máis apropiadas.{{citation needed|date=December 2014}} Un exemplo son as especies crípticas no mosquito vector da [[malaria]] ''[[Anopheles]]'', ou no fungoque causa a [[criptococcose]].
<!--
Pests, species causing diseases, and their vectors, have direct importance for humans. When they are found to be cryptic species complexes, the ecology and virulence of each of these species needs to be reevaluated to devise appropriate control strategies.{{citation needed|date=December 2014}} An example are cryptic species in the [[malaria]] vector ''[[Anopheles]]'', or the fungi causing [[cryptococcosis]].

<!--
When a species is found to comprise in fact several phylogenetically distinct species, each of these typically have smaller distribution ranges and population sizes than reckoned before. These different species can also differ in their ecology, e.g. having different breeding strategies or habitat requirements, which has to be taken into account for appropriate management.{{citation needed|date=December 2014}} For example, [[giraffe]] populations and subspecies differ genetically to such an extent that they may be considered species; while the giraffe as a whole is not considered threatened, considering each cryptic species separately would mean a much higher level of threat.<ref name="Brown 2007" />
