TL;DR: The most unusual, and thus irreplaceable, functions performed by species in three different species-rich ecosystems are fulfilled by only the rare species in these ecosystems.

TL;DR: The fourth-corner method offers a way of analyzing the relationships between the supplementary variables associated with the rows and columns of a binary data table, and is shown to be applicable to a wide class of ecological problems.

TL;DR: In this article, a review of current functioning and responses of Mediterranean marine biogeochemical cycles and ecosystems with respect to key natural and anthropogenic drivers and to consider the ecosystems' responses to likely changes in physical, chemical and socio-economical forcings induced by global change and by growing anthropogenic pressure at the regional scale.

TL;DR: The analysis of the partitioning based on the coral variables suggests that there are significant relationships between benthic and fish assemblages.

TL;DR: Using Bayesian meta-analysis, it is shown that changes in the size structure, diversity and trophic composition of the reef fish community have followed coral declines, suggesting a need for future conservation and management efforts to identify and protect regional refugia.
