Greater Horseshoe Bats Recognize the Sex and Individual Identity of Conspecifics from Their Echolocation Calls

open access: yesAnimals, 2022
The echolocation calls of bats are mainly used for navigation and foraging; however, they may also contain social information about the emitter and facilitate social interactions.

SCUBA noise alters community structure and cooperation at Pederson’s cleaner shrimp cleaning stations

open access: yesFrontiers in Marine Science, 2023
Recreational SCUBA diving is widespread and increasing on coral reefs worldwide. Standard open-circuit SCUBA equipment is inherently noisy and, by seeking out areas of high biodiversity, divers inadvertently expose reef communities to an intrusive source

Experiments with digital video playback [PDF]

open access: yesProceedings of the 1996 ACM SIGMETRICS international conference on Measurement and modeling of computer systems - SIGMETRICS '96, 1996
In this paper we describe our experiments on digital video applications, concentrating on the static and dynamic tradeoffs involved in video playback. Our results were extracted from a controlled series of 272 tests, which we ran in three stages.In the first stage of 120 tests, we used a simple player-monitor tool to evaluate the effects ...

Common Cuckoo Nestling Adapts Its Begging Behavior to the Alarm Signaling System of a Host

open access: yesFrontiers in Ecology and Evolution, 2022
Cuckoo nestlings thrive as avian brood parasites. To acquire sufficient food from the host parents, cuckoo nestlings generally make louder begging calls than host nestlings, but this may cause them to be more likely to attract the attention of predators.

Wild Carrion Crows (Corvus corone) Autonomously Respond to Speech but Show No Difference in Their Response to a Local and a Foreign Language [PDF]

open access: yesAnimal Behavior and Cognition, 2023
Eavesdropping on the vocalizations of other species can be beneficial for wildlife to avoid predator encounters, including encounters with humans. Wild-caught large-billed crows in Tokyo responded more to playback of a foreign language than to Japanese ...

Interactive experiments with a Digital Pattern Playback [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1975
Facilities which make spectrograms immediately available for visual comparison, easy modification of spectral data, and resynthesis of speech have proved to be particularly useful tools in speech research. This paper reports an experiment in which such an interactive research tool—a Digital Pattern Playback (DPP)—is being used to evaluate a spectrum ...

Ungulates’ Behavioral Responses to Humans as an Apex Predator in a Hunting-Prohibited Area of China

open access: yesAnimals, 2023
Large mammals can perceive humans as predators and therefore adjust their behavior to achieve coexistence with humans. However, lack of research at sites with low hunting intensity limits our understanding of how behavioral responses of animals adapt to ...

Precision planter monitoring system based on mobile communication network

open access: yesIET Networks, EarlyView., 2022
Abstract Sowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of

Design and implementation of geographic information system with mobile terminal and 5G network

open access: yesIET Networks, EarlyView., 2022
Abstract Remote insurance mainly completes quotation, insurance application and payment through the PC terminal and mobile terminal, and the premium directly enters the insurance account. This article takes remote insurance as an example. First, it analyses the requirements of the remote insurance and insurance system, and then collects data from the ...

Considerations for designing underwater acoustical playback experiments [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1994
The continued high interest in the effects of man-made sounds on marine wildlife has resulted in increased use of playback experiments. In such experiments, the intent is often to simulate a larger more powerful source of sound, e.g., a drill ship, with a playback of a recording, but using a small portable source system such as a J-11 to play the sound
