Stabilizing effects of group formation by Serengeti herbivores on predator-prey dynamics
Frontiers in Ecology and Evolution, 2022 Predator-prey theory often assumes that potential prey individuals are solitary and evenly distributed in space. This assumption is violated in social, mobile prey, such as many ungulates.

Oxygen minimum zone: An important oceanographic habitat for deep-diving northern elephant seals, Mirounga angustirostris. [PDF]
, 2017 Little is known about the foraging behavior of top predators in the deep mesopelagic ocean. Elephant seals dive to the deep biota-poor oxygen minimum zone (OMZ) (>800 m depth) despite high diving costs in terms of energy and time, but how they ...

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures
Advanced Robotics Research, EarlyView.This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Ecology and EvolutionFeeding ecology is an essential component of an organism's life, but foraging comes with risks and energetic costs. Species in which populations exhibit more than one feeding strategy, such as sea turtles, are good systems for investigating how feeding ...

Learning through the waste: olfactory cues from the colony refuse influence plant preferences in foraging leaf-cutting ants [PDF]
, 2016 Leaf-cutting ants learn to avoid plants initially harvested if they proved to be harmful for their symbiotic fungus once incorporated into the nest.

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors
Advanced Science, EarlyView.Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Connection of mobility and foraging - A cross-cultural analysis
Etnoantropološki Problemi, 2007 The goal of this inquiry is to explore the existence and severity of the liaison in-between mobility and cattle breeding. The author has decided to test the hypothesis of a relation between mobility and cattle breading through quantitative analysis of a

Exploring the evolution of a trade-off between vigilance and foraging in group-living organisms
, 2014 Despite the fact that grouping behavior has been actively studied for over a century, the relative importance of the numerous proposed fitness benefits of grouping remain unclear.
