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 ...
Symbiont-conferred immunity interacts with effects of parasitoid genotype and intraguild predation to affect aphid immunity in a clone-specific fashion
(BioMed Central, 2022)
Background: Host-parasite interactions represent complex co-evolving systems in which genetic and associated phenotypic variation within a species can significantly affect selective pressures on traits, such as host immunity, ...
Dynamics and morphological limitation of intracohort cannibalism during the early life stages of captive barred sorubim Pseudoplatystoma reticulatum
(2021-09-15)
The present study investigated the biological basis of cannibalism in Pseudoplatystoma reticulatum. Newly-hatched P. reticulatum were reared under a standard rearing protocol up to 50 days after hatching (DAH). Fish samples ...

Predation-risk effects of predator identity on the foraging behaviors of frugivorous bats
(2013-05-09)
Predators directly and indirectly affect the density and the behavior of prey. These effects may potentially cascade down to lower trophic levels. In this study, we tested the effects of predator calls (playbacks of bird ...

Decline in numbers of Antarctic skuas breeding at Potter Peninsula, King George Island, Antarctica
(Pacific Seabird Group, 2014-07)
The Brown Skua (Stercorarius antarcticus lonnbergi) and the South Polar Skua (S. maccormicki) breed in Antarctica and, in the case of Brown Skua, on sub-Antarctic islands (Ritz et al. 2008). During the austral summer ...
First record of cannibalism and possible siblicide in geranoaetus polyosoma registered in the atacama desert, Chile Primer registro de canibalismo y posible fratricidio en Geranoaetus polyosoma registrado en el desierto de atacama, Chile
(Universidad de Tarapaca, 2017)
© 2017, Universidad de Tarapaca. All rights reserved. The Variable Hawk (Geranoaetus polyosoma) is a raptor species distributed throughout Chile. In Atacama Desert it feeds particularly lizards and on a littleproportion ...
The disappearance of eggs and larvae from the nests of the Mischocyttarus (Monogynoecus) montei Zikán (Hymenoptera: Vespidae), especially in autumn and winter: Can it mean an adaptive cannibalism to ensure the survival of colonies?
(2016-03-01)
The aim of this study was to verify the disappearance of eggs and larvae from the nests of the Mischocyttarus (Monogynoecus) montei, especially in autumn and winter, and at the same time, to discuss about the cannibalism ...
