One hundred and twenty pigs were used to evaluate the effects of housing indoors on concrete slats or outside in dirt lots on tail biting, weight gains, behavior and immune function for pigs with intact tails or with tails docked. Pig performance was largely not influenced by treatments, even when cannibalism was found. When pigs began biting tails in particular pens, many pigs’ tails were not ...

The distribution and behavior of foraging animals usually imply a balance between resource availability and predation risk. In some predators such as scorpions, cannibalism constitutes an important mortality factor determining their ecology and behavior. Climbing on vegetation by scorpions has been related both to prey availability and to predation (cannibalism) risk. We tested different hypoth...

Please cite this article in press as: Miller, J. Anisolabis maritima, Animal Behaviour (2012 Animals that provide parental care are expected to weigh the value of current offspring against the value of future offspring, such that total investment across all offspring is allocated to maximize lifetime fitness. In this study, we characterize the trade-offs associated with maternal care in the mar...

Cannibalism is induced in larval-stage populations of the Hokkaido salamander, Hynobius retardatus, under the control of a cannibalism reaction norm. Here, I examined phenotypic expression under the cannibalism reaction norm, and how the induction of a cannibalistic morph under the norm leads to populational morphological diversification. I conducted a set of experiments in which density was ma...

A simple nonlinear discrete model is derived for the dynamics of a two-age class population consisting of juveniles and adults that includes cannibalism of juveniles by adults. The model is investigated analytically and numerically. It is shown how even this very simple model, by incorporating the negative and positive feedbacks due to cannibalism, can account for several important phenomena co...

In this paper, we consider a version of the Hayden–Preskill thought experiment in which message thrown into black hole is itself smaller hole. We then discuss implications existence recovery channel for at asymptotic infinity, resulting sharpening information paradox observers who never need to approach horizon. suggest decoherence mechanisms as way resolving sharpened paradox.

Archaeological landscapes of colonial encounter were shaped to varying degrees by mutual mistrust, misunderstanding, anxiety, and the inherent terror frontier violence. In mission encounters Island Melanesia, trope “cannibalism” added a particular tinge these fears colonized other.
