Meal or mate: Exploring the evidence of sexual cannibalism among amphibians

Ecology and Evolution
Active forms of cannibalism that involve predation of live conspecifics occur widely among amphibians, most notably by tadpoles that feed on each other and adults that feed on juveniles.

A diffusive predator-prey system with prey refuge and predator cannibalism

Mathematical Biosciences and Engineering, 2019
This paper is devoted to exploring a diffusive predator-prey system with prey refuge and predator cannibalism. We investigate dynamics of this system, including dissipation and persistence, local and global stability of constant steady states, Turing ...

Eaten alive: cannibalism is enhanced by parasites [PDF]

Royal Society Open Science, 2015
Cannibalism is ubiquitous in nature and especially pervasive in consumers with stage-specific resource utilization in resource-limited environments. Cannibalism is thus influential in the structure and functioning of biological communities. Parasites are

Digitization connects scattered specimens and enables new historical research: Plants from the Lady Franklin Bay Expedition (1881–1884)

PLANTS, PEOPLE, PLANET, EarlyView.
Widespread museum digitization initiatives have made the world's herbaria more accessible than ever, launching a renaissance of specimen use. We highlight the value of digitization to bolster both scientific and historical research using the specimens from the Lady Franklin Bay Expedition (1881–1884) to the Canadian arctic, remembered for its tragedy ...

Indirect plant defense may provide economically important pest suppression in sorghum

Pest Management Science, EarlyView.
Laboratory measures of sorghum direct and indirect plant resistance traits aligned with natural enemy recruitment and pest suppression in the field. Abstract BACKGROUND A promising strategy to optimize biological control of insect pests is selecting crop varieties with indirect defense traits.

Female Filial Cannibalism in the Redhead Goby (Elacatinus puncticulatus) in Captivity

Diversity
Filial cannibalism is the consumption of one’s own viable progeny. It occurs in a range of taxa but is particularly well-documented in fish species. Since parental care in fishes is typically male-biased, it is usually assumed that filial cannibalism is ...

Effect of size sorting on the survival, growth and cannibalism in pikeperch (Sander lucioperca L.) larvae during intensive culture in RAS.

, 2018
The aim of the experiment was to determine the impact of sorting on the growth, survival, and cannibalism of pikeperch larvae during intensive culture in recirculation systems.

The role of developmental plasticity in eco‐phenotypic population dynamics

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Individual variation in development can strongly impact population density via its impact on demography. When this variation in development is caused by developmental plasticity, the resulting effects on population density are characterised as ‘eco‐phenotypic dynamics ...

Intraguild predation in sympatric seals and the effect on a declining population

Journal of Animal Ecology, EarlyView.
This study examined the prevalence, spatial extent, and temporal trends of grey seal intraguild predation (IGP). We demonstrated the utility of integrating disparate datasets to address conservation challenges and highlighted how IGP, while seemingly rare, can hold sympatric species in a predator‐pit and in small populations may contribute to declines.
