Metacommunity Structure of Stream Insects across Three Hierarchical Spatial scales

Ecology and Evolution, 2020
A major challenge in community ecology is to understand the underlying factors driving metacommunity (i.e., a set of local communities connected through species dispersal) dynamics.

Ant semiochemicals limit apterous aphid dispersal [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2007
Some organisms can manipulate the nervous systems of others or alter their physiology in order to obtain benefit. Ants are known to limit alate aphid dispersal by physically removing wings and also through chemical manipulation of the alate developmental pathway. This results in reduced dispersal and higher local densities of aphids, which benefit ants

Native fruit traits may mediate dispersal competition between native and non-native plants [PDF]

, 2012
Seed disperser preferences may mediate the impact of invasive, non-native plant species on their new ecological communities. Significant seed disperser preference for invasives over native species could facilitate the spread of the invasives while ...

Host Phylogeny Is a Major Determinant of Fagaceae-Associated Ectomycorrhizal Fungal Community Assembly at a Regional Scale

Frontiers in Microbiology, 2018
Environmental filtering (niche process) and dispersal limitation (neutral process) are two of the primary forces driving community assembly in ecosystems, but how these processes affect the Fagaceae-associated ectomycorrhizal (EM) fungal community at ...

Dispersal limitation determines large-scale dark diversity in Central and Northern Europe

, 2017
Aim Previous studies indicate that many plant species present in a surrounding region are absent from potentially suitable sites (i.e. they constitute dark diversity).

Coastal pollution limits pelagic larval dispersal [PDF]

Nature Communications, 2011
The ecological impact of large coastal human populations on marine ecosystems remains relatively unknown. Here, we examine the population structure of Patiria miniata, the bat star, and correlate genetic distances with a model based on flow rates and proximity to P.

Dispersal-mediated trophic interactions can generate apparent patterns of dispersal limitation in aquatic metacommunities

, 2012
Dispersal is a major organising force in metacommunities, which may facilitate compositional responses of local communities to environmental change and affect ecosystem function.

WHAT DETERMINES FITNESS WHEN DISPERSAL IS LIMITED? [PDF]

Evolution, 1997
Simple evolutionary models typically assume a homogeneous environment in which all individuals have equal access to resources. However, when dispersal is limited this assumption is unlikely to correspond to reality. Instead, the offspring of relatively fecund parents can be expected to find that resources are scarce because of competition from their ...

Vertebrate-mediated seed rain and artificial perches contribute to overcome seed dispersal limitation in a Mediterranean old field [PDF]

, 2019
Natural regeneration of vegetation is a frequent outcome of land abandonment, although the rate and diversity of such regeneration may be severely restricted by seed dispersal limitation, among other factors.

Disparate dispersal limitation in Geomalacus slugs unveiled by the shape and slope of the genetic–spatial distance relationship [PDF]

, 2020
Long‐term dispersal ability is a key species’ trait constraining species ranges and thus large‐scale biodiversity patterns. Here we infer the long‐term dispersal abilities of three Geomalacus (Gastropoda, Pulmonata) species from their range‐wide genetic ...
