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.

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

BMC 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.

The Life Cycle Relative to Temperature of Protaphorura Armatus (Tullberg) (Collembola: Onychiuridae), a Parathenogenetic Species [PDF]

, 2017
Apparent parthenogenetic reproduction in Collembola has sometimes been attributed to accidental transfer of spermatophores with the food material from one culture to another (Schaller, 1953; Mayer, 1957).

The “Destabilizing” Effect of Cannibalism in a Spatially Explicit Three-Species Age Structured Predator-Prey Model

Complexity, 2017
Cannibalism, the act of killing and consumption of conspecifics, is generally considered to be a stabilising process in ODE models of predator-prey systems. On the other hand, Sun et al.

Characterization of cannibalism in early paralarvae of Patagonian red octopus, Enteroctopus megalocyathus (Gould, 1852), grown in a controlled environment

Journal of the World Aquaculture Society, 2021
In the experimental mariculture of Patagonian red octopus, Enteroctopus megalocyathus, paralarvae rearing showed the highest mortalities. Part of this mortality has been attributed to cannibalism, so we studied the joint effect of paralarvae density and ...

‘Provisions being scarce and pale death drawing nigh, / They'd try to cast lots to see who should die’

Exchanges, 2020
Ballads actively shaped contemporary popular mentalities and through analysing ballads historians are presented with a world of propaganda and persuasion, aimed at a broad spectrum of society from literate to illiterate.

Effects of resource-dependent cannibalism on population size distribution and individual life history in a case-bearing caddisfly. [PDF]

PLoS ONE, 2018
Resource availability often determines the intensity of cannibalism, which has a considerable effect on population size distribution and individual life history. Larvae of the caddisfly Psilotreta kisoensis build portable cases from sedimentary sands and

Galactic cannibalism and CDM density profiles [PDF]

, 2004
Using N-body simulations we show that the process of formation of the brightest cluster galaxy through dissipationless galactic cannibalism can affect the inner cluster dark matter density profile.

Homotypic Cell Cannibalism and Cannibalism Index-A Four Year Study in Inltrating Ductal Carcinoma Breast [PDF]

Journal of Krishna Institute of Medical Sciences University, 2016
Background: Homotypic cell cannibalism is a hallmark of malignant lesions. It serves as an emerging indicator of both the anaplastic grade and invasiveness.

The influence of female oviposition strategy on sibling cannibalism in the ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae)

European Journal of Entomology, 2003
I hypothesized that sibling cannibalism is one of maternal investment in that a female controls sibling cannibalism. To test the hypothesis, I conducted a laboratory experiment and field observations to investigate sibling cannibalism in relation to ...
