Humans as top predators in the ocean: how mechanisms structuring shallow benthic communities are influenced by fishing
(2021)
Throughout history humans have been considered separated from other predators due to their disproportionate influence upon the environment. Large-scale removal of species has simplified food webs resulting in the degradation ...
Effects of predator odour on antipredator responses of Nile tilapia
(2016-10-15)
Several fish species exhibit antipredator responses when exposed to chemicals which indicate risk of predation. One such substance is the scent of a predator (a kairomone) that may induce defensive responses in a potential ...
Behavioral plasticity mitigates risk across environments and predators during anuran metamorphosis
(Behavioral Ecology, 2013)
Most animals metamorphose, changing morphology, physiology, behavior and ecological interactions. Size- and habitat-dependent mortality risk is thought to affect the evolution and plastic expression of metamorphic timing, ...
Influence of cage farming on feeding and reproductive aspects of Pimelodus maculatus Lacépède, 1803 (Siluriformes: Pimelodidae) in the Chavantes reservoir, Brazil
(2014)
This study evaluated the diet and reproductive aspects of the population of Pimelodus maculatus around net cage fish farming in order to assess the possible impacts of this activity. Monthly collections were performed from ...
Native and exotic fishes in a Patagonian reservoir with rainbow trout cage culture: spatial and trophic resource usePoissons indigènes et exotiques dans un réservoir de Patagonie avec aquaculture en cage de truites arc-en-ciel : utilisation des ressources spatiales et trophiques
(EDP Sciences, 2017-08-18)
Although the interactions of exotic salmonids with native Patagonian fishes are well known, little is known about the ecology and impact of farmed fish escapees. Salmonid production in Argentina is largely concentrated in ...
