Elephant Communication
Elephants live in a complex society in which both long- and short-distance communication plays an important role in the ability to locate mates and to maintain intra- and inter-group cohesion. Elephants use a variety of sensory channels in ways both complementary and redundant to achieve this communication, as well as to advertise physiological states, allow […]
Pheromone Communication in Amphibians and Reptiles
This selective review considers herpetological papers that feature the use of chemical cues, particularly pheromones involved in reproductive interactions between potential mates. Primary examples include garter snake females that attract males, lacertid lizards and the effects of their femoral gland secretions, aquatic male newts that chemically attract females, and terrestrial salamander males that chemically persuade […]
Chemosensory signals in stream habitats: implications for ecological interactions
The combination of varying aquatic habitats and flow regimes creates a complex stimulus environment from which sensory information can be extracted. Previous studies with crayfish in artificial stream settings have shown that altering the temporal and spatial structure of an odor plume modifies orientation behavior. Exposure to more temporally complex odor signals enables crayfish to […]
