Limited Predator-Induced Dispersal in Whiteflies

PLoS ONE, 2012
Whereas prey are known to avoid habitats with their predators, it is less well established whether they are triggered to emigrate to new habitats when exposed to predators in their current habitat. We studied plant-to-plant dispersal of adult whiteflies in response to the presence of predatory mites on the plant on which the whiteflies were released ...

Dispersal and fire limit Arctic shrub expansion [PDF]

Nature Communications, 2021
Abstract Arctic shrub expansion alters carbon budgets, albedo, and warming rates in high latitudes but remains challenging to predict due to unclear underlying controls. Observational studies and models typically use relationships between observed shrub presence and current environmental suitability (bioclimate and topography) to ...

Environmental filtration and dispersal limitation explain different aspects of beta diversity in desert plant communities

Global Ecology and Conservation, 2022
Environmental filtration and spatial processes are associated with variation in ecological communities and biodiversity; however, their relative importance to species beta diversity at different sampling scales has not been fully explored in desert plant

Distinct Community Assembly Mechanisms of Different Growth Stages in a Warm Temperate Forest

Diversity, 2023
Community phylogenetic structure and diversity analysis are useful complements to species-centric approaches in biodiversity studies by providing new insights into the processes that drive community assembly.

Environmental heterogeneity blurs the signature of dispersal syndromes on spatial patterns of woody species in a moist tropical forest.

PLoS ONE, 2018
We assessed the relative importance of dispersal limitation, environmental heterogeneity and their joint effects as determinants of the spatial patterns of 229 species in the moist tropical forest of Barro Colorado Island (Panama). We differentiated five

Do spatially-implicit estimates of neutral migration comply with seed dispersal data in tropical forests?

PLoS ONE, 2013
Neutral community models have shown that limited migration can have a pervasive influence on the taxonomic composition of local communities even when all individuals are assumed of equivalent ecological fitness.

Linking pollen limitation and seed dispersal effectiveness

Ecology Letters, 2023
Abstract Seed production and dispersal are crucial ecological processes impacting plant demography, species distributions and community assembly. Plant–animal interactions commonly mediate both seed production and seed dispersal, but current research often examines pollination and seed dispersal separately, which hinders our ...

Long-Distance Wind-Dispersal of Spores in a Fungal Plant Pathogen: Estimation of Anisotropic Dispersal Kernels from an Extensive Field Experiment [PDF]

, 2014
Given its biological significance, determining the dispersal kernel (i.e., the distribution of dispersal distances) of spore-producing pathogens is essential. Here, we report two field experiments designed to measure disease gradients caused by sexually-

Kin selection in interactions between gametes: Gamete competition, gamete limitation, and sex allocation

Frontiers in Ecology and Evolution, 2023
Kin selection on one hand, and gamete interactions in post-ejaculatory sexual selection on the other are two major research themes that have risen to prominence over the past half century and have simultaneously developed into central fields of research ...

The use of bird perches and artificial bat roosts to overcome dispersal and establishment limitation in bracken-dominated deforested areas

Global Ecology and Conservation
The failure of seeds to arrive at suitable sites (dispersal limitation) and/or unsuitable conditions for germination, seedling survival and growth (establishment limitation) can impede the regeneration of tropical forests.
