Habitat Quality Determines Dispersal Decisions and Fitness in a Beetle – Fungus Mutualism
Frontiers in Ecology and Evolution, 2021 Delayed dispersal of sexually mature offspring is a fundamental component of cooperative breeding. In ambrosia beetles, female offspring temporarily remain in their natal nest and refrain from reproduction, instead investing in alloparental care ...

Cues of maternal condition influence offspring selfishness. [PDF]
PLoS ONE, 2014 The evolution of parent-offspring communication was mostly studied from the perspective of parents responding to begging signals conveying information about offspring condition.

European Journal of Entomology, 2006 The incidence of sibling cannibalism in clutches of Harmonia axyridis infected by the male-killing Spiroplasma was compared with that in uninfected clutches, and the way in which fitness compensation was realized by sibling cannibalism was investigated ...

Evidencia en video de fratricidio y canibalismo, movimiento de polluelos e interacciones con depredadores en nidos de Circus cyaneus [PDF]
, 2018 During a nest-camera study of Hen Harriers (Circus cyaneus), we recorded siblicide, cannibalism, movement of nestlings by adult birds, and interactions with predators.

Expression in antennae and reproductive organs suggests a dual role of an odorant-binding protein in two sibling Helicoverpa species. [PDF]
PLoS ONE, 2012 Odorant-binding proteins (OBPs) mediate both perception and release of semiochemicals in insects. These proteins are the ideal targets for understanding the olfactory code of insects as well as for interfering with their communication system in order to ...

Do cannibalistic fish forage optimally ? An experimental study of prey size preference, bioenergetics of cannibalism and their ontogenetic variations in the African catfish Heterobranchus longifilis [PDF]
, 2014 This study relied on the day-by-day analysis of bioenergetics and prey size preference in isolated cannibals of the African catfish Heterobranchus longifilis (13-57 mm standard length, 3-500 mg dry body mass, n = 153) that were offered ad libitum ...

Maternal manipulation of hatching asynchrony limits sibling cannibalism in the predatory mitePhytoseiulus persimilis [PDF]
Journal of Animal Ecology, 2008 1. Sibling cannibalism is a common phenomenon in the animal kingdom but entails a high risk of direct and inclusive fitness loss for the mother and her offspring. Therefore, mechanisms limiting sibling cannibalism are expected to be selected for. One way of maternal manipulation of sibling cannibalism is to influence hatching asynchrony between nearby ...

Necrotrophic growth of periodontopathogens is a novel virulence factor in oral biofilms [PDF]
, 2017 The oral use of antimicrobial agents embedded in toothpastes and mouth rinses results in an oral microbial massacre with high amounts of dead bacteria in close proximity to few surviving bacteria.

Association between molecular markers and behavioral phenotypes in the immatures of a butterfly
Genetics and Molecular Biology, 2018 Newly hatched caterpillars of the butterfly Heliconius erato phyllis routinely cannibalize eggs. In a manifestation of kin recognition they cannibalize sibling eggs less frequently than unrelated eggs.

Asynchronous hatching in a non-avian species:a test of the hurry-up hypothesis [PDF]
, 2017 The hurry-up hypothesis suggests that completing reproduction as soon as possible is favoured when the quantity or quality of resources used for breeding declines over time.
