Savanna Rodents’ Selective Removal of an Encroaching Plant’s Seeds Increased With Grass Biomass

Frontiers in Ecology and Evolution, 2021
In savannas across the planet, encroaching woody plants are altering ecosystem functions and reshaping communities. Seed predation by rodents may serve to slow the encroachment of woody plants in grasslands and savannas.

Videography reveals in-water behavior of loggerhead turtles (Caretta caretta) at a foraging ground

Frontiers in Marine Science, 2016
Assessing sea turtle behavior at the foraging grounds has been primarily limited to the interpretation of remotely-sensed data. As a result, there is a general lack of detailed understanding regarding the habitat use of sea turtles during a phase that ...

Social inhibition maintains adaptivity and consensus of honeybees foraging in dynamic environments [PDF]

Royal Society Open Science, 2019
To effectively forage in natural environments, organisms must adapt to changes in the quality and yield of food sources across multiple timescales. Individuals foraging in groups act based on both their private observations and the opinions of their ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

Population Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

A Multiscale Review of Behavioral Variation in Collective Foraging Behavior in Honey Bees

Insects, 2019
The emergence of collective behavior from local interactions is a widespread phenomenon in social groups. Previous models of collective behavior have largely overlooked the impact of variation among individuals within the group on collective dynamics ...

Semi‐intensive shrimp farms as experimental arenas for the study of predation risk from falcons to shorebirds

Ecology and Evolution, 2021
Varying environmental conditions and energetic demands can affect habitat use by predators and their prey. Anthropogenic habitats provide an opportunity to document both predation events and foraging activity by prey and therefore enable an empirical ...

The Possible Role of Body Temperature in Modulating Brain and Body Sizes in Hominin Evolution

Frontiers in Psychology, 2022
Many models have posited that the concomitant evolution of large brains and body sizes in hominins was constrained by metabolic costs. In such studies, the impact of body temperature has arguably not been sufficiently addressed despite the well ...

Does foraging efficiency vary with colony size in the fairy martin Petrochelidon ariel? [PDF]

, 2009
Colonial breeding occurs in a wide range of taxa, however the advantages promoting its evolution and maintenance remain poorly understood. In many avian species, breeding colonies vary by several orders of magnitude and one approach to investigating the ...

Neural Mechanisms of Foraging [PDF]

Science, 2012
Looking for Greener Pastures Humans, like other animals, have evolved to forage. Brain-imaging studies by Kolling et al. (p. 95 ) suggest that activity in the dorsal anterior cingulate cortex supplies a continuous signal of environmental ...
