Trophic Dynamics and Feeding Ecology of Skipjack Tuna (Katsuwonus pelamis) off Eastern and Western Taiwan

open access: yesMolecules, 2022
The skipjack tuna (Katsuwonus pelamis) is a mesopredator fish species with seasonal abundance in waters off Taiwan. Regional ecological and life-history information has been historically lacking for this species. In recent years, stable isotope analysis (

Bistability induced by generalist natural enemies can reverse pest invasions [PDF]

open access: yes, 2016
Reaction-diffusion analytical modeling of predator-prey systems has shown that specialist natural enemies can slow, stop and even reverse pest invasions, assuming that the prey population displays a strong Allee effect in its growth.

Mind the gap: Experimental tests to improve efficacy of fladry for nonlethal management of coyotes

open access: yesWildlife Society Bulletin, 2019
Coyotes (Canis latrans) are the top predator of livestock in the contiguous United States. Developing more effective nonlethal tools to prevent coyote depredation will facilitate coexistence between livestock producers and coyotes.

On some Free Boundary Problems of the Prey-predator Model [PDF]

open access: yes, 2014
In this paper we investigate some free boundary problems for the Lotka-Volterra type prey-predator model in one space dimension. The main objective is to understand the asymptotic behavior of the two species (prey and predator) spreading via a free ...

Evaluating fladry designs to improve utility as a nonlethal management tool to reduce livestock depredation

open access: yesWildlife Society Bulletin, 2015
Nonlethal deterrents against carnivores are important components to protecting livestock and conserving carnivore populations. However, the performance of the visual deterrent called fladry, a historical tool used to defend livestock from carnivores, is ...

Energy cost and return for hunting in African wild dogs and cheetahs

open access: yesNature Communications, 2016
The long-distance hunting behaviour of African wild dogs is thought to be energetically costly. Here, Hubel et al. show that multiple opportunistic short-distance hunts and group feeding make African wild dogs in mixed woodland savannah energetically ...

Fear of predators alters herbivore regulation of soil microbial community function

open access: yesEcology and Evolution, 2023
Fear of predation can affect important ecosystem processes by altering the prey traits expression that, in turn, regulates the quantity and quality of nutritional inputs to soil.
