Understanding community assembly rules in managed floodplain food webs

open access: yesEcosphere, 2021
Community assembly has been an important topic in ecological research and theory for over a century. Recently, restoration ecologists have emphasized the use of community assembly rules, such as environmental filtering, to better inform management ...

A Roadmap for Sustainable Disease, Pest, and Weed Management

open access: yesBiology and Life Sciences Forum, 2023
Effective disease, pest, and weed control are essential for achieving sustainable agricultural practices. The ever-growing global population, coupled with the increasing demand for food, poses a significant challenge to agriculture systems globally.

Processes structuring macrophyte metacommunities in Mediterranean ponds: combining novel methods to disentangle the role of dispersal limitation, species sorting and spatial scales [PDF]

open access: yes, 2019
Aim: Metacommunity ecology is a vibrant area of research that has received increased attention in recent years, since it provides a framework to assess the underlying dispersal- and niche-based processes that create non-random and ecologically meaningful

Plant Community Assembly [PDF]

open access: yesThe Bulletin of the Ecological Society of America, 2014
In graduate school in the 1970s, discussions of Hutchinson’s multivariate niche (1957) and the role of competitive exclusion in structuring communities provided exciting new insights into patterns of community assembly. At the same time, however, I was immersed in the literature of plant community ecology and building my own impressions of tropical and

Continuous assembly required: Perpetual species turnover in two‐trophic‐level ecosystems

open access: yesEcosphere, 2023
Community assembly is often treated as deterministic, converging on one or at most a few possible stable endpoints. However, in nature, we typically observe continuous change in community composition, which is often ascribed to environmental change.

Experimental salt marsh islands: a model system for novel metacommunity experiments [PDF]

open access: yes, 2017
Shallow tidal coasts are characterised by shifting tidal flats and emerging or eroding islands above the high tide line. Salt marsh vegetation colonising new habitats distant from existing marshes are an ideal model to investigate metacommunity theory ...

Fungal community assembly in drought-stressed sorghum shows stochasticity, selection, and universal ecological dynamics. [PDF]

open access: yes, 2020
Community assembly of crop-associated fungi is thought to be strongly influenced by deterministic selection exerted by the plant host, rather than stochastic processes.

Species assembly in model ecosystems, I: Analysis of the population model and the invasion dynamics [PDF]

open access: yes, 2010
Recently we have introduced a simplified model of ecosystem assembly (Capitan et al., 2009) for which we are able to map out all assembly pathways generated by external invasions in an exact manner. In this paper we provide a deeper analysis of the model,
