Non-Random Sibling Cannibalism in the Marine Gastropod Crepidula coquimbensis. [PDF]

open access: yesPLoS ONE, 2013
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 ...

Predator cannibalism can shift prey community composition toward dominance by small prey species

open access: yesEcology and Evolution, 2022
Cannibalism among predators is a key intraspecific interaction affecting their density and foraging behavior, eventually modifying the strength of predation on heterospecific prey.

A test of male infanticide as a reproductive tactic in a cichlid fish [PDF]

open access: yesRoyal Society Open Science, 2017
Infanticide and offspring cannibalism are taxonomically widespread phenomena. In some group-living species, a new dominant individual taking over a group can benefit from infanticide if doing so induces potential mates to become reproductively available ...

Cannibalism in Holocene muricid snails in the Beagle Channel, at the extreme southern tip of South America: an opportunistic response? [PDF]

open access: yes, 2013
This work documents the occurrence of drillholes on muricid Trophon geversianus shells from a Holocene raised marine deposit in the Beagle Channel, located on the extreme southern tip of South America (~ 55ºS).

Dynamic behaviors of Lotka–Volterra predator–prey model incorporating predator cannibalism

open access: yesAdvances in Difference Equations, 2019
A Lotka–Volterra predator–prey model incorporating predator cannibalism is proposed and studied in this paper. The existence and stability of all possible equilibria of the system are investigated.

Cannibalism as a life boat mechanism [PDF]

open access: yes, 1988
Under certain conditions a cannibalistic population can survive when food for the adults is too scarce to support a non-cannibalistic population. Cannibalism can have this lifeboat effect if (i) the juveniles feed on a resource inaccessible to the adults;

Cannibalism in cultured Eurasian perch, Perca fluviatilis (Actinopterygii: Perciformes: Percidae)—Implication of maternal influence, kinship, and sex ratio of progenies [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2015
Background. Intra cohort cannibalism is one of the main factors that affects the growth and survival of cultured fishes, especially in the larval and juvenile stages.

Cannibalism and activity rate in larval damselflies increase along a latitudinal gradient as a consequence of time constraints

open access: yesBMC Evolutionary Biology, 2017
Background Predation is ubiquitous in nature. One form of predation is cannibalism, which is affected by many factors such as size structure and resource density.

Egg Cannibalism Varies With Sex, Reproductive Status, and Egg and Nymph Ages in Arma custos (Hemiptera: Asopinae)

open access: yesFrontiers in Ecology and Evolution, 2021
Background: Egg cannibalism is common in nature. In China, Arma custos (Hemiptera: Asopinae) has been widely used as a natural enemy to control agricultural and forestry pests. A previous study showed that adult A. custos devour their eggs.
