Abstract The Atlantic goliath grouper Epinephelus itajara is the largest species of groupers
in the Atlantic Ocean, reaching over 2 m total length and 400 kg. It has an ontogenetic …

Ecological similarity plays an important role in biotic interactions. Increased body size
similarity of competing species, for example, increases the strength of their biotic …

Selection of nursery habitats by marine fish, such as European sea bass (Dicentrarchus
labrax), is poorly understood. Identifying and protecting the full range of juvenile nursery …

Abiotic factors and hydrological disturbances associated with climatic phenomena are
challenges to be overcome by many estuarine resident fish. This study investigates whether …

Estuarine mangroves are often considered nurseries for the Atlantic Goliath grouper
juveniles. Yet, the contributions of different estuarine primary producers and habitats as …

Unraveling factors that enable the coexistence of species occupying similar niches is a
challenge in Ecology. In the Amazon basin, several piranha species (Serrasalmidae) co …

Despite the economic importance and susceptibility to overfishing of the dog snapper
Lutjanus jocu, information on their first life stages and the use of nursery habitats remains …

Simple Summary Trophic niches, as one of the important dimensions of niche theory, show
the nutritional requirements of species; they can reflect their position in the ecosystem …

Classifying organisms into guilds is a good strategy to deal with taxonomic differences, and
possibly to compare systems worldwide to address ecosystemic questions. Functional guilds …

Stable isotope analysis of δ13C and δ15N have been broadly used in ecological studies to
access trophic interactions between organisms, and the flow of energy and contaminants …
