A dissemination article about metapopulation dynamics in arid regions (in Portuguese only)

The kind of metapopulation approach depicted in Fig. 1 does not include everything that is commonly assigned to metapopulation ecology. Other approaches have been reviewed, for instance theore-tical work based on lattice models6,7,11–13 and conservation-oriented empirical studies14–16. The term ‘metapopulation’ is often used for

Richard Levins developed the concept of a metapopulation to describe “a population of populations”. More specifically Jan 14, 2008 Abstract. This paper outlines a conceptual and theoretical framework for single- species metapopulation dynamics based on the Levins model May 23, 2012 The metapopulation concept was established in the literature in the late 1960s, though some ecologists had formulated ideas about spatially Jan 5, 2021 Two necessary features of a metapopulation have already been established here that individual subpopulations have a realistic chance of En metapopulation är ett ekologiskt begrepp för system av lokala populationer av samma art som är rumsligt åtskilda.

"Metapopulation ecology has gained significance as we confront landscapes that are increasingly fragmented. This volume gives an excellent survey of the field with a careful account of both strengths and weaknesses of the approach. Metapopulation ecology concerns organisms that are dependent upon discrete patches of suitable habitat . . .

ABSTRACT Due to anthropogenic pressures, African lion (Panthera leo) populations in Kenya and Tanzania are increasingly limited to fragmented populations. Lions living on isolated habitat patches exist in a matrix of less-preferred habitat. A framework of habitat patches within a less-suitable matrix describes a metapopulation.

Classical metapopulation theory assumes that landscapes are comprised of a large number of patches available for colonization. This chapter examines how landscape heterogeneity influences the composition of local communities. Straightforward extensions of standard metapopulation models have been used in this chapter to examine the raised questions.
