Metapopulation dynamics over 25 years of a beetle

4. En metapopulation behöver inte innebär ett exakt bevarande av något ursprungligt utan bör tvärtom ge ett visst utrymme för en evolution och anpassning till nya förhållanden som kan vara olika inom meta-popuationens område. 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. Metapopulation scale is referred to the states that individuals move unusually from one place or even across the habitats that are not suitable for feeding and breeding to reach the other populations.

Metapopulation ideas play an increasingly important role in landscape ecology and conservation biology. Metapopulation metapopulation threshold conditions for a similar spatially realistic system. Eriksson (1996) has instead emphasized the importance of the qualitative dynamics of the patches, and argued that many vascular plants, rather than Measuring metapopulation size in terms of both patch occupancy (Milden et al. 2006, Belinchon et al. 2017) and numbers of plants (Meulebrouck et al.

In this way, we show that the evolved trait variation especially impacts metapopulation size, but that most variation in the metapopulation dynamics is related to spatial forcing.

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. Metapopulation, in ecology, a regional group of connected populations of a species.

Metapopulation – Wikipedia

The metapopulation persists if λ M > δ, where δ = μ/c and λ M, called the metapopulation capacity, is the leading eigenvalue of a landscape or metapopulation matrix M [4,5]. To extend this model to migratory metapopulations with N B breeding patches and N W non-breeding patches, we model the occupancy probability in year t of breeding patches p i ( t )( i =1 … We conclude that the increasing spatial synchrony of metapopulation dynamics in 1993–2013 (figure 1c,d), reflected in the increasing amplitude of metapopulation fluctuations (figure 1a), is caused by increasing frequency of dry weather in July (figure 3b,c), which leads to withering of host plants and subsequent larval mortality.
