DOI: 10.1002/ece3.3894
Abstract: Abstract Sibling 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… read more here.

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

DOI: 10.1002/ece3.8894
Abstract: Abstract Cannibalism among predators is a key intraspecific interaction affecting their density and foraging behavior, eventually modifying the strength of predation on heterospecific prey. Interestingly, previous studies showed that cannibalism among predators can increase or… read more here.

Low levels of cannibalism increase fitness in an herbaceous tortrix moth

DOI: 10.1007/s00265-018-2439-0
Abstract: Cannibalism is relatively common in herbaceous insects, but studies looking at life-history traits on conspecific versus herbaceous diets reveal a mix of outcomes. In some taxa, fitness is highest on a conspecific diet, but in… read more here.

Does sexual cannibalism secure genetic benefits of polyandry in a size-dimorphic spider?

DOI: 10.1007/s00265-020-02890-5
Abstract: Females mate multiply despite numerous costs. It is well established that polyandry can result in sexual conflict, favoring male adaptations that prevent sperm competition often to the disadvantage of the female. Such adaptations are extreme… read more here.

The effects of food level and conspecific density on biting and cannibalism in larval long-toed salamanders, Ambystoma macrodactylum

DOI: 10.1007/s004420100641
Abstract: Previous studies have examined abiotic and biotic factors that facilitate agonistic behavior. For larval amphibians, food availability and conspecific density have been suggested as important factors influencing intraspecific aggression and cannibalism. In this study, we… read more here.

Abstract: Cannibalism can be a significant factor limiting the survival of pike, Esox lucius, early life stages in both natural and aquaculture conditions. In the present research, type I cannibalism was studied in pike larvae (size… read more here.

DOI: 10.1007/s10905-020-09742-0
Abstract: Cannibalism is a widespread behavioral phenomenon that is often thought to be an adaptive plastic response to limited environmental resources. However, cannibalism can potentially come at a fitness cost to an individual if one consumes… read more here.

DOI: 10.1016/j.aaf.2016.12.001
Abstract: While juvenile cannibalism plays an important role in the evolution of organisms in natural populations, it is a serious problem in aquaculture. A number of genetic and environmental factors result in different rates of cannibalism.… read more here.

Paternal investment with an uncertain future: effects of predator exposure on filial cannibalism and nesting behaviour

DOI: 10.1016/j.anbehav.2017.07.024
Abstract: Owing to trade-offs between investment in current and future reproduction, factors that diminish a parent's survival prospects, such as predation threat, are expected to increase investment in existing young. Nevertheless, effects of predation risk on… read more here.

DOI: 10.1016/j.anbehav.2018.03.003
Abstract: Although the consumption of one's own offspring is often viewed as maladaptive, under some circumstances this behaviour can be a beneficial way to terminate parental care. When the costs of providing care are extremely high… read more here.
