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.

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 ...

FLIES AND FLOWERS III: ECOLOGY OF FORAGING AND POLLINATION
, 2015 Diptera are important flower visitors and pollinators for many plant species and in a variety of habitats. Although Diptera are not as well studied as other groups of pollinators, there is a growing literature that we review here about the ecology of ...

Food deprivation changes chemotaxis behavior in Caenorhabditis elegans
Biophysics and Physicobiology, 2019 Exploring for food is important in food-deprived condition. Chemotaxis is one of the important behaviors to search food. Although chemotactic strategies in C.

Temperature effects on Florida applesnail activity: implications for snail kite foraging success and distribution [PDF]
, 2002 The endangered Florida snail kite (Rostrhamlls sociaiJilis) feeds exclusively on applesnails (Pomacea pailiclosa), yet we lack direct observations that link applesnail behavior to snail kite foraging success.

Anterior Cingulate Engagement in a Foraging Context Reflects Choice Difficulty, Not Foraging Value
Nature Neuroscience, 2014 Previous theories predict that human dorsal anterior cingulate (dACC) should respond to decision difficulty. An alternative theory has been recently advanced that proposes that dACC evolved to represent the value of 'non-default', foraging behavior ...

, 2014 Predators alter prey dynamics by direct killing and through the costs of antipredator responses or risk effects. Antipredator behavior includes proactive responses to long-term variation in risk (e.g., grouping patterns) and reactive responses to short ...

European Journal of Entomology, 2008 While the key role of termites in the decomposition of litter in the tropics has been acknowledged for a long time, much less information exists on their importance in the recycling of dung of primary consumers, especially herbivores.
