Dominance of species sorting over dispersal at microgeographical scales in polluted lotic ecosystems

Environmental Pollution, 2023
Global rivers, particularly those in populated urban areas, are challenged by multiple stressors such as pollution from anthropogenic activities. Dissecting the relative role of each ecological process involved in structuring biotic communities is fundamental in both theoretical and applied ecology.

Coexistence through spatio‐temporal heterogeneity and species sorting in grassland plant communities

Ecology Letters, 2008
AbstractThe effect of spatial heterogeneity on species coexistence relies on the degree of niche heterogeneity in the habitat and the ability of species to exploit the available niche opportunities. We studied species coexistence in a perennial grassland, and tested whether small‐scale disturbances create environmental heterogeneity that affects ...

The Persistence and Sorting of Incipient Species

2000
Abstract The emergence of full-fledged neospecies is preceded by the evolution of incipient neospecies (species in statu nascendi). They have distinctive ecological pro files and/or genetic systems, but are not sufficiently divergent to warrant recognizing them as neospecies.

Seed availability constrains plant species sorting along a soil fertility gradient

Journal of Ecology, 2010
Summary 1. Spatial variation in species composition within and among communities may be caused by deterministic, niche‐based species sorting in response to underlying environmental heterogeneity as well as by stochastic factors such as dispersal limitation and variable species pools.

Affinity chromatography ofEuglena: A novel means of sorting phytoplankton species

Experientia, 1977
Euglena species can be selectively bound to nylon using an E. gracilis strain Z antiserum. This affinity chromatography procedure isolates living cells and is genus-specific.

A quantitative analysis of species sorting across organisms and ecosystems

Ecology, 2014
The estimation of the relative roles of environment, space, and their interactions in structuring community composition is one of the central topics of community ecology. I conducted a quantitative review to determine if the degree of species sorting (SS) by the abiotic environment varied predictably between organism types and ecosystems.

Linking grassland plant diversity to species pools, sorting and plant traits

Journal of Ecology, 2011
Summary1. Variation in species pools can affect plant diversity, but it remains unclear whether the magnitude of the response varies because of resource availability, community invasibility or other environmental factors, and whether colonization along environmental gradients reflects niche‐based species sorting or neutral processes.2.

Mutual cohesion and cell sorting-out among four species of cellular slime moulds

Journal of Cell Science, 1978
ABSTRACT Interspecific cell cohesion among 4 species of cellular slime moulds, Dictyostelium discoideum, D. mucoroides, D. purpureum and Polysphondylium violaceum has been studied. Binary mixtures of aggregation-stage cells of the 4 species were shaken in suspension, one species of each pair being labelled with PH]thymidine.

Differential sorting of individuals in territorial species affects apparent habitat quality

The Journal of Wildlife Management, 2013
ABSTRACTTerritoriality leads to non‐random sorting of individuals into habitats of differing quality. This can affect empirical estimates of population growth rate (λ), a measure of habitat quality, such that habitat‐specific λ varies with population size.
