Prey density affects predator foraging strategy in an Antarctic ecosystem
Ecology and Evolution, 2020 Studying the effects of prey distribution on predator behavior is complex in systems where there are multiple prey species. The role of prey density in predator behavior is rarely studied in closed ecosystems of one predator species and one prey species,

Prey-tracking behavior and prey preferences in a tree-climbing firefly [PDF]
PeerJ, 2019 Prey-tracking behavior is common in snail-killing predators, but in the family Lampyridae, this behavior has been validated in only a single species even though this Coleopteran family includes many specialist snail predators.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Sociobiology, 2017 Ants are among the insects involved in cadaveric decomposition processes, as they exhibit predatory and necrophagous behavior. Red ants exhibit an aggressive behavior, which impacts carcass colonization, accelerates or delays the decomposition rates and ...

Effects of Neonatal Handling on Play Behavior and Fear Towards a Predator Odor in Juvenile Rats
, 2008 The effects of brief daily separation, also known as handling, during the first 2 weeks of life on play behavior and fearfulness toward a predatory odor were assessed in juvenile rats.

Anatomical Sciences Education, EarlyView.Abstract A lack of minimum legal standards for body donation programs undermines recent strides by anatomy professionals to promote ethical best practices in the United States (US). In particular, the commercialization of the dead by nontransplant tissue banks poses a risk to the public trust in academic body donation programs.

Chemotactic predator-prey dynamics
, 2010 A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady ...

Journal of the Association for Information Science and Technology, EarlyView.Abstract Timely detection of problematic research is essential for safeguarding scientific integrity. To explore whether social media commentary can serve as an early indicator of potentially problematic articles, this study analyzed 3815 tweets referencing 604 retracted articles and 3373 tweets referencing 668 comparable non‐retracted articles.
