Landscape Effects on Population Distributions and Dynamics

(p.291) 7 Landscape Effects on Population Distributions and Dynamics
Essentials of Landscape Ecology

The distribution and dynamics of populations reflect the interplay between dispersal and demography with landscape structure. Understanding how landscape structure affects populations is essential to effective habitat management and species conservation, especially within landscapes undergoing habitat loss and fragmentation as a result of human land-use activities. This chapter thus begins with an overview of the effects of habitat loss and fragmentation on populations, followed by a discussion of species distribution modeling. Then, because population assessment figures so prominently in evaluating a species’ extinction risk to landscape change, the chapter considers the different classes of population models used to estimate population growth rates and population viability, including the use of metapopulation and spatially explicit simulation models.

Keywords:   habitat loss and fragmentation, edge effects, species distribution models, resource-selection functions, ecological niche models, population viability analysis, extinction threshold, metapopulation, source-sink population dynamics, spatially explicit population model
