J. Neurochem. (2010) 112, 1138–1146. Abstract Stress and corticosterone level are thought to negatively associate with neurogenesis in mammalian brains. Social support can diminish many adverse e...

Pronounced spatial variation in recruitment occurs in many marine invertebrate and fish populations and is thought to be critical to the demography of these species. In this study I examined the importance of habitat structure and the presence of conspecific residents to spatial variation in larval settlement and recruitment in a temperate fish Tautogolabrus adspersus. I define settlement as the movement of individuals from the water column to the benthic habitat, while I refer to recruitment as numbers of individuals surviving some arbitrary period of time after settlement. Experiments in ...

Conspecifics are usually considered competitors negatively affecting food intake rates. However, their presence can also inform about resource quality by providing inadvertent social information. F...

Abstract. We investigated the effects of pilferage on caching behavior in the Merriam's kangaroo rat by manipulating two factors associated with pilferage: the

Snijders et al. present a field-based experimental study of the effects of group size and sex composition on social foraging in Trinidadian guppies. Their results indicate that sex differences in sociality do not necessarily imply an unequal ability to benefit from social presence.

Rats incorporate circa 22kHz ultrasonic alarm cries into their defense pattern in response to a predator threat. These calls are dependent on conspecific presence, show gender differences, and tend to be emitted from a place of relative safety. Rats emit sonic defensive threat vocalizations when app …

In some animals, unfamiliarity with a place and the presence of a conspecific can change movement patterns, often altering individuals’ routes, exploration, and the directions taken. Patterns such as these can affect individual survival, and thus might be present across a wide range of taxa, although mostly vertebrates have been studied. We used a native Kentucky land snail (white-lipped globe snail, Cepaea hortensis) to investigate how snail size, familiarity and the recent presence of a conspecific affect movement of snails in a novel environment. We also tested whether presence of a fami...

In female mice, Mus domesticus, reunion with a same-sex conspecific is associated with intense ultrasonic vocalization. We examined whether the palatability of a familiar food eaten by a demonstrator mouse and the motivational state of the conspecific observer could modulate the number of ultrasonic …

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We investigated the effects of pilferage on caching behavior in the Merriam’s kangaroo rat by manipulating two factors associated with pilferage: the presence of a conspecific, and the opportunity for pilferage. In one experiment we assessed animals in either ‘‘Stealer’ ’ or ‘‘Victim’ ’ roles and measured changes in caching, space use, and behavior after caches were pilfered. Victims shifted from a majority scatter-hoarding to a majority larder-hoarding strategy after their caches were pilfered by the Stealer. In E...
