Intracohort cannibalism and methods for its mitigation in cultured freshwater fish

open access: yesReviews in Fish Biology and Fisheries, 2017
Cannibalism is a common phenomenon that occurs in over 30 fish families. Most of the species are valuable objects of aquaculture and cannibalism is highly undesirable.

Planktonic larval stages—an adaptation to lower predation rates in the pelagic environment?

open access: yesLimnology and Oceanography, EarlyView.
Abstract A majority of marine benthic macroinvertebrate and fish species have planktonic larval stages that disperse in the water column from days to months. However, the adaptive significance of pelagic larvae, and whether predation is higher in the pelagic or the benthic environment, is still debated, partly due to a lack of studies assessing larval ...

Stomach contents from invasive American bullfrogs Rana catesbeiana (= Lithobates catesbeianus) on southern Vancouver Island, British Columbia, Canada [PDF]

open access: yes, 2013
Invasive alien American bullfrog populations are commonly identified as a pernicious influence on the survival of native species due to their adaptability, proliferation and consequent ecological impacts through competition and predation. However, it has

Interplay of trophic relaxation and directional selection shapes eco‐evolutionary responses to selective harvest in predator–prey systems

open access: yesOikos, EarlyView.
Fisheries‐induced evolution (FIE) describes the evolutionary changes in life‐history traits exhibited by target species in response to selective fishing pressures. Current studies predominantly focus on single‐species contexts, often assuming stationary natural selection and neglecting the impact of interacting species.

Intraspecific predation in immature Coenagrion puella (L.): a switch in food selection? (Zygoptera: Coenagrionidae) [PDF]

open access: yes, 1997
Observations on cannibalism in outdoor insectaries are presented. The behavioural interactions are described. Cannibalism (in both sexes) occurred only during periods of cold weather.

Male mate‐choice copying: a neglected aspect of sexual selection

open access: yesOikos, EarlyView.
Mate‐choice copying occurs when the choices of others influence an individual's mating preferences. While this behavior has been observed across various species, most research has focused on female copying behavior. However, male mate‐choice copying warrants independent attention due to the distinct benefits and costs it entails for males compared to ...

Note on the persistence and stability property of a stage-structured prey–predator model with cannibalism and constant attacking rate

open access: yesAdvances in Difference Equations, 2020
We revisit the persistence and stability property of a stage-structured prey–predator model with cannibalism and constant attacking rate. By using the differential inequality theory and Bendixson–Dulac criterion, we show that if the system without ...

Zhang Yimou's 'Blood simple':cannibalism, remaking and translation in world cinema [PDF]

open access: yes, 2014
Zhang Yimou’s A Woman, A Gun and A Noodle Shop (2009) remakes the Coen brothers’ Blood Simple (1984) in a way that re-imagines the earlier film in a Chinese setting, adapting and recreating the narrative, but the film cannot be regarded as being aimed ...

Sexual cannibalism and population viability

open access: yesEcology and Evolution, 2018
Some behaviours that typically increase fitness at the individual level may reduce population persistence, particularly in the face of environmental changes. Sexual cannibalism is an extreme mating behaviour which typically involves a male being devoured

Fiber Processing of Recombinant Spider Silk Proteins

open access: yesJournal of Polymer Science, EarlyView.
Recombinant spider silk proteins are produced using biotechnological tools to mimic the properties of natural ones. Modern spinning techniques replicating the natural spinning process can produce biomimetic fibers. Additionally, nonnatural spinning techniques can create fibers in the submicron range, broadening the range of applications.
