Changes in the feeding ecology of South American sea lions on the southern Brazilian coast over the last two decades of excessive fishing exploration
(Springer, 2018-09)
In the last decades, an increasing fishing effort and a decreasing trend in fish catches have been observed in southern Brazil. Considering that marine mammals and fisheries usually compete for the same resources, it is ...
The ecological role of brachiopods in the Namuncurá MPA/Burdwood Bank, off southern South America
(Springer Verlag Berlín, 2019-08)
Extant brachiopods have been very little studied, despite being abundant along the Argentine marine platform and southern areas of the Subantarctic region. In this survey, we examined brachiopod assemblages from the Namuncurá ...
Allee effect in models of interacting species
(Pergamon-Elsevier Science Ltd, 2021-12)
The search for more realistic models for interacting species has produced many adaptations of the original Lotka-Volterra equations, such as the inclusion of the Allee effect and the different Holling's types of functional ...
Naticid boreholes on a tertiary cylichnid gastropod from southern Patagonia
(Institute of Malacology, 2006-12)
The fossil communities are in clear disadvantage when it comes to study the interactions among the species included in them. However, predation on shells gives us the possibility to examine at least some of these interactions. ...
Nos volvemos a encontrar: primer registro de depredación de un visón americano (Neovison vison) por un tucúquere (Bubo virginianus magellanicus)

El visón americano es un carnívoro semiacuático de América del Norte. Fue introducido en Argentina y Chile (década 1930) en criaderos peleteros, a partir de los cuales se originaron poblaciones silvestres. Actualmente se ...
A case of cannibalism in Achala Cooper lizard Pristidactylus achalensis, an endemic lizard to the highest mountain areas in Central Argentina (Squamata: Leiosauridae)
(Societas Europaea Herpetologica, 2019-08-07)
Cannibalism, defined by the process of eating conspecific individuals, seems to occur opportunistically as a by-product of normal predatory behaviour and generally it has been linked to island populations. Pristidactylus ...
Trophic overlap between marine mammals and fisheries in subtropical waters in the western South Atlantic
(Inter-Research, 2020-04)
Marine mammals and humans are apex predators and both may compete for fish in ecosystems under continuous fishing pressure. We assessed the degree of trophic overlap between prey species found in the diet of 5 marine mammals ...
Depredación organizacional : las consecuencias del uso del poder en la organización
(Universidad IcesiFacultad de Ciencias Administrativas y Económicas, 2014-07-01)
The concept of “predation” in the field of organization is usually associated with the deterioration of its
resources. However, when a population ecology approach is used, there is a focus on the relationships
between ...
