Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders [PDF]
Integrative Zoology, EarlyView.Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

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

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

Frontiers 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.

OMEGA - 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
Advances 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.

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

Determination of serum adenosine deaminase and xanthine oxidase activity in Kangal dogs with maternal cannibalism [PDF]
Veterinary World, 2017 Aim: Kangal dogs, known as guard dogs in many countries of the world, have been found to eat their own puppies during their first 24 h following birth, which is called as maternal cannibalism.
