Non-Random Sibling Cannibalism in the Marine Gastropod Crepidula coquimbensis. [PDF]
Sibling cannibalism is commonly observed in marine species. For instance, intrabrood cannibalism has been documented in marine gastropods with direct development, suggesting a relationship between embryo behavior and the evolution of life history ...

Avian sibling cannibalism: Hoopoe mothers regularly use their last hatched nestlings to feed older siblings. [PDF]
Sibling cannibalism is relatively common in nature, but its evolution in birds and certain other vertebrates with extended parental care had been discarded. Here, however, we demonstrate its regular occurrence in two European populations of the Eurasian hoopoe (Upupa epops) and explore possible adaptive and non-adaptive explanations.

Brood reduction caused by sibling cannibalism in Isodontia harmandi (Hymenoptera: Sphecidae), a solitary wasp species building communal brood cells. [PDF]
Sibling rivalry or brood reduction prevailing within bird nests is effectively avoided in solitary aculeate nests because the larvae of wasps and bees usually develop in each brood cell.

Direct and indirect effect of cannibalism and intraguild predation in the two sibling Harmonia ladybird beetles [PDF]
In this study, we focused on the direct (i.e., predation) and indirect (i.e., potential threat from coexisting with a larger individual) effects of cannibalism and intraguild predation (IGP) during larval stages of two sibling ladybird beetles.

Growth, cannibalism, and survival relations in larvae of European catfish, Silurus glanis (Actinopterygii: Siluriformes: Siluridae)—attempts to mitigate sibling cannibalism [PDF]
Background. Under culture conditions, intra-cohort cannibalism is one of the main factors that affects the growth and survival of fishes, especially during the early life stages of carnivorous species.

Occurrence and evolution of cannibal behaviour in extant snakes. [PDF]
ABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

Maternal hatching synchronization in a subsocial burrower bug mitigates the risk of future sibling cannibalism. [PDF]
AbstractSibling cannibalism—the killing and consumption of conspecifics within broods—carries a high risk of direct and inclusive fitness loss for parents and offspring. We reported previously that a unique vibrational behavior shown by the mother of the subsocial burrower bug,Adomerus rotundus(Heteroptera: Cydnidae), induced synchronous hatching ...

The FsrA-Mediated Iron-Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis. [PDF]
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Sympatric coexistence of sibling species Harmonia yedoensis and H. axyridis (Coleoptera: Coccinellidae) and the roles of maternal investment through egg and sibling cannibalism [PDF]
The sibling species H. yedoensis Takizawa coexists sympatrically and simultaneously with H. axyridis only on pine trees in Japan. To elucidate the mechanisms enabling coexistence of these two sympatric sibling species, a laboratory experiment was ...

Nestling Growth and Brood Reduction in the Southern Yellow-Billed Hornbill (<i>Tockus leucomelas</i>). [PDF]
In the southern yellow‐billed hornbill, Tockus leucomelas, we found first‐hatched nestlings had a higher growth rate and that growth rate was negatively correlated with mortality, such that early hatching nestlings were more likely to survive than their younger siblings. Brood reduction was more likely to occur in larger broods and was predicted by the
