SYNCHRONY IN SLOW–FAST METACOMMUNITIES [PDF]

International Journal of Bifurcation and Chaos, 2009
The synchronization of metacommunities due to dispersal among patches is analyzed in the case of slow–fast populations. The analysis is performed by studying a standard model with the fast population dispersing when special meteorological conditions are present.

Using phylogenetic clade composition to understand biogeographical variation in functional traits

Frontiers of Biogeography, 2017
Assemblage-level studies of mean trait variation are common in macroecology. However, how phylogenetic relationships among species affect trait-based macroecological patterns is still unresolved.

Using null models to compare bacterial and microeukaryotic metacommunity assembly under shifting environmental conditions

Scientific Reports, 2019
Temporal variations in microbial metacommunity structure and assembly processes in response to shifts in environmental conditions are poorly understood.

Negotiating a Fragmented World: What Do We Know, How Do We Know It, and Where Do We Go from Here?

Diversity
Genetic diversity determines evolutionary potential. Without a variable genome, natural selection cannot act. Habitat fragmentation is the single largest threat to global biodiversity, as it reduces or eliminates gene flow among populations, thereby ...

Life Between Patches: Incorporating Microbiome Biology Alters the Predictions of Metacommunity Models

Frontiers in Ecology and Evolution, 2019
Although most models conceptualize a metacommunity as a collection of habitat patches embedded in a matrix that is not hospitable to life, new applications of metacommunity theory to host-microbiome systems have shown this assumption to be flawed ...

Introducing untb, an R Package For Simulating Ecological Drift Under the Unified Neutral Theory of Biodiversity [PDF]

The distribution of abundance amongst species with similar ways of life is a classical problem in ecology. The unified neutral theory of biodiversity, due to Hubbell, states that observed population dynamics may be explained on the assumption of per ...

A process-based metacommunity framework linking local and regional scale community ecology

, 2019
The metacommunity concept has the potential to integrate local and regional dynamics within a general community ecology framework. To this end, the concept must move beyond the discrete archetypes that have largely defined it (e.g. neutral vs.

Effects of dispersal and temperature variability on phytoplankton realized temperature niches

Ecology and Evolution
Phytoplankton species exhibit fundamental temperature niches that drive observed species distributions linked to realized temperature niches. A recent analysis of field observations of Prochlorococcus showed that for all ecotypes, the realized niche was,

Gricean metacommunication

Mind & Language
Three main approaches exist for finessing the cognitive demands of Grice's model of communication (a notorious problem): namely, deflationism , modularity , and interpretivism .
