Functional traits illuminate the selective impacts of different fishing gears on coral reefs

Fishing down nutrients on coral reefs

Fishing is widely considered a leading cause of biodiversity loss in marine environments, but the potential effect on ecosystem processes, such as nutrient fluxes, is less explored. Here, we test how fishing on Caribbean coral reefs influences biodiversity and ecosystem functions provided by the fish community, that is, fish-mediated nutrient capacity. Specifically, we modelled five processes o...

Coral Reefs: Fishing for Sustainability

Sustainable fisheries must ultimately reduce poverty while maintaining ecosystem productivity. On coral reefs, managing for 'concave' trophic pyramids might be a win-win for people and ecosystems, by providing higher-value fisheries and maintaining important ecological functions.

Functional Roles of Sponges on Coral Reefs

ALTHOUGH a small group of carbonate excavating sponges can dismantle reefs, and some sponges can overgrow corals, it is now known that sponges also substantially benefit coral reefs and associated ecosystems. Sponges benefit reefs by efficiently filtering small (<5um) organic particles from the water column, binding live corals to the reef frame, facilitating regeneration of broken reefs, provi...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
