Trophic ontogenetic shifts of the dragonfly Rhionaeschna variegata: the role of larvae as predators and prey in Andean wetland communities
(Edp Sciences, 2014-03)
Body size strongly influences the type and strength of species interactions. Animals with complex life cycles, such as dragonflies, usually go through different stages that include a variation in body size and may involve ...
Olfactory cues mediating prey-searching behaviour in interacting aphidophagous predators: are semiochemicals key factors in predator-facilitation?
(WILEY-BLACKWELL, 2010-06-21)
Based on their effect on prey populations, predators can interact synergistically, additively, or antagonistically.
Predator attraction by semiochemicals in response to herbivory is well documented; however,
the possibility ...
Toxicity of the fungicide trifloxystrobin on tadpoles and its effect on fish-tadpole interaction
(Pergamon-Elsevier Science Ltd, 2012-02)
Contamination of aquatic systems is a major environmental stress that can interfere with predator-prey interactions, altering prey or predator behavior differentially. We determined toxicity parameters of the fungicide ...
Predation of nabis punctipennis on acyrthosiphon pisum in the presence of the alternative prey aphis craccivora in alfalfa
(Universidad de Concepción, 2020)
The feeding behavior of the generalist predator Nabis punctipennis Blanchard (Nabidae) on Acyrthosiphon pisum Harris (Aphididae), two hemipterans common in alfalfa in Chile, was studied in a laboratory experiment using A. ...
Intestinal, Body and Tail Plasticity in Rhinella schneideri (Bufonidae) Tadpoles Induced by a Predator Insect (Belostoma elegans)
(Hikari Ltd, 2009-04)
According to the adaptive plasticity hypothesis, predator-induced traits in potential prey animals are expected to have costs for those organisms in predatorfree environments. In this study, we analysed if the intestinal ...
