Social referencing is the seeking of information from another individual and the use of that information to evaluate a situation. It is a well-documented ability in human infants but has not been studied experimentally in nonhuman primates. Seventeen young nursery-reared chimpanzees (14 to 41 months old) were observed in a standard social referencing(More)
Encroachment by invasive plants is a leading threat to rare butterflies. Restoration plans increasingly recommend herbicides to control invasive plants within butterfly habitats. Few studies address the effects of these herbicides on at-risk butterflies. The effects of two graminicides (fluazifop-p-butyl and sethoxydim) and a surfactant (Preference®) were(More)
Millions of long-lasting insecticide treated nets (LLINs) have been distributed as part of the global malaria control strategy. LLIN ownership, however, does not necessarily guarantee use. Thus, even in the ideal setting in which universal coverage with LLINs has been achieved, maximal malaria protection will only be achieved if LLINs are used both(More)
Drosophila larvae change from exhibiting attraction to aversion as the concentration of salt in a substrate is increased. However, some aversive concentrations appear to act as positive reinforcers, increasing attraction to an odour with which they have been paired. We test whether this surprising dissociation between the unconditioned and conditioned(More)
There is a growing appreciation for the role of sniffing in the formation of the olfactory percept. With this in mind, monitoring and measurement of sniffing is an important aspect of olfactory experiments. There are several methods for measuring human sniffs concurrent with odor delivery in olfactory experiments. Here, we set out to compare the temporal(More)
The use of captive rearing to promote recovery of endangered butterflies has substantially increased over the last decade. These programs have the potential to play a significant role in butterfly population recovery, but the effects of captive conditions are poorly understood and rarely are traits of captive individuals assessed relative to traits in their(More)
BACKGROUND To evaluate the effect of vascular clips and endovascular coils placed for intracranial aneurysms and arteriovenous malformations on whole-brain computed tomography (CT) angiography and perfusion. METHODS A 320-detector row dynamic volume CT system imaged 11 patients following surgical placement of vascular clips or endovascular coils. The(More)
