Cannibalism in temporary waters: Simulations and laboratory experiments revealed the role of spatial shape in the mosquito Aedes albopictus. [PDF]

open access: yesPLoS ONE, 2018
Cannibalism is a commonly observed phenomenon in arthropod species having relevant consequences for population dynamics and individual fitness. It is a context-dependent behaviour and an understanding of the factors affecting cannibalism rate is crucial ...

Intra-instar larval cannibalism in Anopheles gambiae (s.s.) and Anopheles stephensi (Diptera: Culicidae) [PDF]

open access: yesParasites & Vectors, 2016
Background Cannibalism has been observed in a wide range of animal taxa and its importance in persistence and stability of populations has been documented. In anopheline malaria vectors the inter-instar cannibalism between fourth- and first-instar larvae

Effects of Alternative Prey Density on Cannibalism in Adult Female Neoseiulus californicus

open access: yesEcology and Evolution
Neoseiulus californicus is a key predatory mite species used for controlling pest mites on crops such as strawberries and corn. Cannibalism is common among predatory mites, but studies on how prey density influences the cannibalistic behavior of N ...

Cannibalism

open access: yesOMEGA - Journal of Death and Dying, 2015
A dataset of 73 variables was complied on 345 serial killers, 31 of whom who engaged in cannibalism. A distinction was made between those who engaged only in cannibalism, those who engaged in necrophilia, and those who engaged in both or neither. Those who engaged in both cannibalism and necrophilia were the most psychiatrically disturbed and deviant,

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 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.

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.

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 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.

Sublethal exposure to diatomaceous earth increases net fecundity of flour beetles (Tribolium confusum) by inhibiting egg cannibalism. [PDF]

open access: yesPLoS ONE, 2014
Population regulation results from an interplay of numerous intrinsic and external factors, and for many insects cannibalism is such a factor. This study confirms a previously-reported observation that sublethal exposure to the fossilized remains of ...
