Curvature
A measure to characterize the shape of bat calls, where frequency~= timeP (where P is an integer value). If P is a positive number the call is upward curving, if P is a negative number the call is downward curving.
Day-Only Recording Mode
Records from 90 minutes before sunrise to 90 minutes after sunset. This requires a GPS fix. Available only on Chorus and Ranger.
Detector Placement
There is a strong relationship between the quantity and quality of bat call recordings, and how the detector is deployed. The better your detector placement the more likely it is that you will record high quality data from which you can obtain reliable species identification and indices of bat activity.
Directional Microphone
A directional microphone has a specific area of detection that is shaped like a lobed or Christmas tree pattern, primarily focused in front of the microphone. This means that the microphone is designed to capture sound mainly from a specific direction or within a limited angle. While a directional microphone may have a narrower area […]
Directionality
In bat echolocation, directionality refers to the bat’s ability to focus its emitted sound in a specific direction. By controlling the directionality of their echolocation pulses, bats can concentrate the sound energy to accurately locate objects or prey. Higher-frequency calls tend to exhibit greater directionality.
Dur
Pulse Duration; the duration of the pulse, measured in milliseconds (ms)
Dusk & Dawn Recording Mode
Records from 90 minutes before to 90 minutes after sunrise and sunset. This requires a GPS fix. Available only on Chorus and Ranger.
Echolocation Pulse
An echolocation pulse is a specialized sound emitted by bats for navigation and locating objects. It possesses distinct characteristics like volume, frequency, directionality, and shape.
Echolocation variability
Bats exhibit the ability to modify their echolocation based on various factors such as their environment, behavior, and the presence of other bats.
Ecomorphological guilds
Ecomorphological guilds are classifications of bats that take into account their wing morphology, functional characteristics, preferred foraging microhabitat and foraging strategy.
