Trophic niche changes during settlement in the Argentine hake Merluccius hubbsi reveal the importance of pelagic food post metamorphosis
(Inter-Research, 2019-06)
Among those factors that determine the success of a fish cohort, trophic interactions play a key role, especially during the larval and juvenile stages. The Argentine hake Merluccius hubbsi is the most abundant demersal ...
Segregación trófica parcial entre especies de Gambusia (Cyprinodontiformes: Poeciliidae) en un humedal natural de Cuba
(2019)
Gambusia punctata y Gambusia puncticulata muestran un patrón de distribución muy característico: G. punctata domina arroyos de montaña, mientras que G. puncticulata es más abundante en humedales de zonas bajas. No obstante, ...
Feeding strategy of the non-native rainbow trout, Oncorhynchus mykiss, in low-order Patagonian streams
(Wiley, 2013-05-03)
The dietary composition and feeding strategy of rainbow trout, Oncorhynchus mykiss (Walbaum), in two low-order Patagonian streams were studied. Benthic macroinvertebrate availability was estimated in both riffles and pools. ...
Taxonomical entities of the Chotoy spinetail Schoeniophylax phryganophilus (Aves: furnariidae) at the Paraná river floodplain, Argentina
(Universidad Antonio Nariño, 2009-12)
The objective of this research was to study the barely known taxonomical entities of passerine Chotoy spinetail —Schoeniophylax phryganophilus— at the Paraná River floodplain, with the purpose of giving quantified data ...
Structural and functional approaches to describe polychaete assemblages: ecological implications for estuarine ecosystems
(2011)
Polychaete assemblages are of special interest when studying dynamic environments such as estuaries because of their high plasticity in life strategies to cope with environmental variability. We tested the hypothesis that ...
Padrões de uso e compartilhamento de recursos alimentares de elasmobrânquilos do sul do Brasil
(2019)
O nicho alimentar de uma espécie pode ser compartimentalizado em três distintos componentes: espacial (onde o indivíduo se alimenta), temporal (quando se alimentar) e trófico (do quê se alimenta). Assim, a divergência de ...

Stable isotopes reveal different dependencies on benthic and pelagic pathways between Munida gregaria ecotypes
(Elsevier, 2018-12)
Forage species are key nodes in the energy fluxes between benthic and pelagic zones. The squat lobster, Munida gregaria, is a common forage species of the Southern Hemisphere and its abundance is increasing. This species ...
