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.

Written by a world renowned biologist, this volume offers a comprehensive synthesis of current research in this rapidly expanding area of population biology. Metapopulation theory is used to analyse the effects of habitat fragmentation on birds in the temperate zone, integrating various explanations for the paucity of species in isolated ecotopes.

To fill the knowledge gap, we propose a modeling framework that incorporates nonrandom and sex‐specific dispersal into metapopulation theory. It allows us to ask how female‐biased (e.g., in mammals) or male‐biased (e.g., in birds) dispersal can influence persistence of sexual organisms. Spatially realistic theory of metapopulation ecology. Hanski I (1). Much of spatial ecology since the late 1960s has been dominated by two theories, the dynamic theory of island biogeography and the classical metapopulation theory. The latter theory largely replaced the former one in the 1980s, especially in conservation applications. 2001-02-27

Here, we present a novel extension to metapopulation theory, applicable to migratory species. The migratory metapopulation model differs from the classic metapopulation in having two patch types: breeding and non-breeding patches, with directed movement between these … 2018-06-14 E&EB 122 - Lecture 29 - Island Biogeography and Invasive Species. Chapter 1. Introduction [00:00:00] Professor Stephen Stearns: You guys had a little bit of fun getting dressed up and doing some stuff up on stage last Friday, and so I though that I would actually have a little fun myself. To fill the knowledge gap, we propose a modeling framework that incorporates nonrandom and sex‐specific dispersal into metapopulation theory. It allows us to ask how female‐biased (e.g., in mammals) or male‐biased (e.g., in birds) dispersal can influence persistence of sexual organisms.

I conclude that the classical metapopulation theory is most appropriate for species living in highly Metapopulation theory is perhaps most valuable for these species, since it is here that regional patterns of existence will not be predictable on the basis of local population dynamics alone. More recently, however, the metapopulation concept has been broadened to recognize that all species have local and regional 1996.

Metapopulation Ecology - Ilkka Hanski - häftad - Adlibris
Metapopulation theory developed in terrestrial ecology provides applicable frameworks for interpreting the role of local and regional processes in shaping species distribution patterns. Yet, empirical testing of metapopulation models on microbial communities is essentially lacking. The term metapopulation was coined by Richard Levins in 1969 to describe a model of population dynamics of insect pests in agricultural fields, but the idea has been most broadly applied to species in naturally or artificially fragmented habitats. In Levins' own words, it consists of "a population of populations". Metapopulation theory is largely based on a dynamic aspect of population maintenance that embraces a regional perspective (Levins, 1970).
However, classical metapopulation theory [Levins, R. (1970) Lect. Notes Math.
