The freshwater fish assemblage in most estuaries is not as species rich as the marine
assemblage in the same systems. Coupled with this differential richness is an apparent …

The understanding of the role of fishes in the trophic functioning of estuaries has increased
in stages over many decades. It began with qualitative and quantitative dietary studies …

The emergence of plant-based economies have dominated evolutionary models of Middle
and Late Holocene pre-Columbian societies in South America. Comparatively, the use of …

Carbon and Nitrogen stable isotopes and stomach contents analyses were used to
investigate an estuarine fish food web and identify the contribution of these two methods to …

Seabird species within a community are expected to have distinct trophic niches according
to foraging methods and body size, but some seabirds exploit fishery waste which can be …

Stable isotope analysis (SIA) of carbon (δ 13 C) and nitrogen (δ 15 N) was used to analyse
the macrobenthic food web dynamics in the Gulf of Gaeta (Tyrrhenian sea, Central Italy) …

Ecosystems are connected through the movement of organisms, nutrients, energy, and
matter. The connection and dependence between aquatic habitats enhances our capacity to …

Analysis of the stable isotope signatures of carbon (C) and nitrogen (N) of foods and
consumers has led to some preliminary understanding of the relative importance of …

Introduction Competition embodies species struggle for space and food and is, therefore, a
critical evolutionary mechanism influencing species spatiotemporal patterns and …

Variations in the relative importance of autotrophic sources to aquatic consumers along
environmental gradients and the trophic role of mangrove-derived detritus to marine coastal …
