An empirical study of the evolutionary significance of cannibalism in tree-hole mosquitoes (Diptera : Culicidae) from ecological and biological perspectives [PDF]

open access: yes, 1995
To be adaptive, optimality theory suggests that behavioural traits should maximise the fitness of the carrier by spread of genotypes through a population.

Investigating the Heat Stability and Inactivation Conditions of Decapod Iridescent Virus 1 (DIV1)

open access: yesAnimal Research and One Health, EarlyView.
Heat treatment effectively inactivates decapod iridescent virus 1 (DIV1) under milder conditions than current WOAH recommendations. DIV1 infectivity was eliminated at 56°C for 30 min, 60°C for 15 min, or 70°C for 1 min, providing optimized heat treatment strategies for aquaculture biosecurity and seafood safety.

Revenge of the host: Cannibalism, ontogenetic niche shifts, and the evolution of life-history strategies in host-parasitoid systems [PDF]

open access: yes, 2012
Question: How does cannibalism in the host alter the evolution of a parasitoid’s oviposition strategy? Can differences in cannibalism risk between parasitized vs. healthy hosts alter the stage foraging of parasitoids?

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Cannibalism in Tyrannosaurus rex

open access: yes, 2010
Background: Tyrannosaurus rex was one of the largest terrestrial carnivores of all time, and consequently its ecology and diet have been the focus of much discussion.

Maternal cannibalism in two populations of wild chimpanzees [PDF]

open access: yes, 2019
Maternal cannibalism has been reported in several animal taxa, prompting speculations that the behavior may be part of an evolved strategy. In chimpanzees, however, maternal cannibalism has been conspicuously absent, despite high levels of infant ...

Cannibalism and Femininity

open access: yes, 2021
Moving between an example of metaphorical cannibalism in the Old English poem Judith to one of literal cannibalism in Game of Thrones, this chapter argues that an enforcement is a form of jettisoned social dismemberment: it is the perpetration of a ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

open access: yesEcography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...
