Ecosystems can be incredibly complex, with many interacting species. In many habitats, predators shape they behavior of prey and prey shape the behavior of predators. This paper provides a detailed look at the predator-prey ...

Calling in the ultrasonic range enables small bats to orient themselves in the dark and track down tiny insects. Louder calls travel farther, improving a bat's ability to detect their prey.

Searching for food at night can be tricky. To find prey in the dark, bats use echolocation, their "sixth sense." But to find food faster, some species, like Molossus molossus, may search within hearing distance of their echolocating ...

Clicks, squeaks, chirps, and buzzes...though they may be difficult to distinguish to our ears, such sounds are used by echolocating animals to paint a vivid picture of their surroundings. By generating a sound and then listening ...

Small insects that would normally be undetectable to bats using echolocation suddenly become detectable when they occur in large swarms. Arjan Boonman of Tel-Aviv University and colleagues present these findings in PLOS Computational ...

Over millions of years, porpoises have developed powerful biosonar with high accuracy and intelligence to detect and track prey in noisy underwater environments. The sound source in a porpoise is about one half of the wavelength ...

Bats are creatures of the night and are accustomed to complete darkness. They harness their hypersensitive hearing to feed, to fend off prey and to mate.

New findings reported by LMU researchers challenge a generally accepted model of echolocation in bats. They demonstrate that bats require far less spatial information than previously thought to navigate effectively.

The sonar system of bats exploits spatial information in a way similar to our sense of sight, despite the different anatomy of eyes and ears. In a new study, scientists at the Max Planck Institute for Ornithology in Seewiesen ...
