WebFish ecology in IRES is driven by source-sink dynamics, and therefore long-term survival is underpinned by colonization opportunities. Barriers that inhibit these movements are … WebJun 13, 2024 · Source-sink dynamics emerged as an important ecological concept in the 1980s [1, 2] and grew in influence through subsequent decades [].Source-sink theory and ideas now influence how ecologists study spatially structured populations, and source-sink assessments are increasingly considered in conservation and management decisions.
Source–sink dynamics - Oxford Reference
The source-sink model of population dynamics has made contributions to many areas in ecology. For example, a species' niche was originally described as the environmental factors required by a species to carry out its life history, and a species was expected to be found only in areas that met these niche … See more Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms. Since quality is likely to vary among patches of habitat, … See more Land managers and conservationists have become increasingly interested in preserving and restoring high quality habitat, particularly where rare, threatened, or endangered species are concerned. As a result, it is important to understand how to … See more • Battin J (December 2004). "When good animals love bad habitats: ecological traps and the conservation of animal populations".

This question is central to source-sink theory. Ultimately, it depends on the organisms and the way they move and distribute themselves between habitat patches.

All cross-scale source/sink issues can produce both negative and positive effects on the scales above and below their levels, i.e., cross-scale effects. The challenge then, is to develop adaptive management strategies for social-ecological landscapes (SELs) with social norms that foster cooperative responses ... bryton 10 notice

WebThis is the sink. If the surplus population from the source moves into the sink, however, the sink population can be sustained indefinitely. Ecologists assume that organisms are able … WebNov 30, 2012 · The paired source and sink concepts are used increasingly in ecology and Earth sciences, but they have evolved in divergent directions, hampering communication … WebTimothy D. Schowalter, in Insect Ecology (Fifth Edition), 2024 Population structure across landscapes also influences source-sink relationships that determine population viability and ability to recolonize patches following disturbances.
