Predator-prey interactions between Synbranchus marmoratus (Teleostei: Synbranchidae) and Hypsiboas pulchellus tadpoles (Amphibia: Hylidae): Importance of lateral line in nocturnal predation and effects of fenitrothion exposure
(Pergamon-Elsevier Science Ltd, 2010-11)
Environmental contaminants can disrupt interactions between aquatic species by altering community structure. We explored predator-prey interactions between marbled swamp juvenile eels (Synbranchus marmoratus; predator) and ...
Predator-prey body size relationship in temporary wetlands: Effect of predatory insects on prey size spectra and survival
(EDP Sciences, 2016-03)
The effect of predators on prey size structure in aquatic communities has been well studied in lentic permanent habits, but less attention has been placed on temporary environments. The biota of seasonal Andean wetlands ...
Predator occurrence and perceived predation risk determine grouping behavior in guanaco (Lama guanicoe)
(Wiley Blackwell Publishing, Inc, 2018-05)
Grouping behavior of social ungulates may depend on both predator occurrence and perceived predation risk associated with habitat structure, reproductive state, and density of conspecifics. Over 3 years, we studied grouping ...
Complementary effects of different predators of leaf-cutting ants: Implications for biological control
(Academic Press Inc Elsevier Science, 2019-01)
Predators that share a prey can interact negatively or positively, depending on whether there is intraguild predation or they facilitate the consumption of the shared prey. Leaf-cutting ants may become pests, thus, knowing ...
The influence of tadpole density and predation on the behavioral responses of two Neotropical anurans
(Universidade de Sao Paulo, 2019-12)
The risk of predation can prompt a variety of responses from the prey species, including changes in morphology, life history, and behavior. Adaptive responses to predators may depend on the amount of resources available ...
Predation and interaction strength of octopuses and sea stars on different functional groups of the rocky intertidal shores of the Patagonian coast
(Springer, 2019-11)
Predation is one of the main structuring forces in rocky intertidal communities, though with an effect depending on the environmental context and conditions. On the stressful Patagonia shores of Argentina, experimental ...
Octopuses and drilling snails as the main suspects of predation traces on shelled molluscs in West Antarctica
(Springer, 2021-11-25)
The analysis of predation traces on shelled taxa is a primary source of data for studying predator–prey interactions in both modern and past ecosystems, and provides valuable information along ecological and evolutionary ...
Diet overlap among top predators at the South Orkney Islands, Antarctica
(Springer, 2019-02)
In order to understand interspecific trophic relationships between top predators, we analyzed diet information for nine bird and two seal species collected in the austral summer from 1996 to 2000 at South Orkney Islands. ...
Population regulation in large northern herbivores: Evolution, thermodynamics, and large predators
(Blackwell Verlag GmbH Berlin, 2000-12)
Understanding population regulation of large northern herbivores like cervids has important practical and theoretical implications. Corrective measures for high densities of cervids must be based on theory and thus necessitate ...
Intraspecific variation in body size of bumblebee workers influences anti-predator behaviour
(Wiley Blackwell Publishing, Inc, 2020-03-01)
Flower-dwelling predators make flowers dangerous foraging sites for pollinators, potentially affecting their anti-predator behaviour. Moreover, predation vulnerability often varies among pollinators' body sizes with ...
