Foraging dives of sperm whales in the north-western Mediterranean Sea [PDF]
, 2012 Oceanic odontocetes rely on echolocation to forage on pelagic or benthic prey, but their feeding ecology is difficult to study. We studied sperm whale foraging dives during summer in the north-western Mediterranean, using visual and passive acoustic ...

Surfactant affects the tool use behavior of foraging ants
Ecotoxicology and Environmental Safety, 2022 Surfactants are commonly used in detergents, soaps and agrichemical products. After use, the residual surfactants can be dispersed into environmental compartments, directly or indirectly affecting aquatic and terrestrial organisms.

Teasing apart the effects of seed size and energy content on rodent scatter-hoarding behavior. [PDF]
PLoS ONE, 2014 Scatter-hoarding rodents are known to play a crucial role in the seed dispersal of many plant species. Numerous studies have indicated that both seed size and the energy content of seeds can affect rodent foraging behavior.

The foraging behaviour of hummingbirds through space and time [PDF]
, 2015 Central place foragers, such as territorial hummingbirds, feed from resources that tend to be constant in space and to replenish with time (e.g. nectar in flowers).

Intraspecific Variation among Social Insect Colonies: Persistent Regional and Colony-Level Differences in Fire Ant Foraging Behavior. [PDF]
PLoS ONE, 2015 Individuals vary within a species in many ecologically important ways, but the causes and consequences of such variation are often poorly understood. Foraging behavior is among the most profitable and risky activities in which organisms engage and is ...

Foraging strategies in grey seals (Halichoerus grypus) : foraging effort and prey selection [PDF]
, 2009 Swimming speeds and prey selection of temporally captive, wild grey seals (Halichoerus grypus) were investigated in relation to prey characteristics in an experimental set-up at the Sea Mammal Research Unit (St Andrews, UK).

The Influence of abiotic factors on the foraging activity of Cephalotes borgmeieri (Kempf, 1951)
Sociobiology, 2023 The foraging activity can be defined as the search for food resources and is an activity of utmost importance for ant colony maintenance. Workers can be exposed to adverse environmental conditions during foraging, and because of it, some species can ...

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Advanced Robotics Research, EarlyView.Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...
