Metapopulation theory identifies biogeographical patterns among core and satellite marine bacteria scaling from tens to thousands of kilometers. Metapopulation theory has become a common framework in conservation biology and it is sometimes suggested that a metapopulation approach should be used for management of large mammals. However, it has also been suggested that metapopulation theory would not be applicable to species with long generations compared to those with short ones. Metapopulation theory identifies biogeographical patterns among core and satellite marine bacteria scaling from tens to thousands of kilometers.

Some demographic and genetic consequences of environmental heterogeneity for biological control. Metapopulation theory states that all local pop - ulations eventually go extinct, but that dispersal among them has a quantitative influence on population dynamics, including rescuing them from extinction or allowing for recolonization after extinction (Hanski and Simberloff 1997). Therefore, a metapopulation approach may be View Academics in Metapopulation Theory on Academia.edu. Metapopulation ecology is a field that is richer in theory than in empirical results. Many existing empirical studies use an incidence function approach based on spatial patterns and key assumptions about extinction and colonization rates.

Metapopulation, originally pioneered by Levins, refers to a series or set of local populations, each existing on a patch of suitable habitat that is separated from other occupied patches by unsuitable terrain.

#Metapopulation #audioversity~~~ Metapopulation ~~~Title: What is Metapopulation? Metapopulation theory is appropriate for analyzing fragmented landscapes because it combines empirical landscape features with species‐specific information to produce direct information on population extinction risks. This approach contrasts with descriptions of habitat fragments, which provide only indirect information on risk. Metapopulation theory identifies biogeographical patterns among core and satellite marine bacteria scaling from tens to thousands of kilometers.
