Resource Ephemerality Drives Social Foraging in Bats

Authors: Edward Hurme Publish Date: November 19, 2018 Description: Observations of animals feeding in aggregations are often interpreted as events of social foraging, but it can be difficult to determine whether the animals arrived at the foraging sites after collective search [1–4] or whether they found the sites by following a leader [5, 6] or […]

Movement Ecology of the Mexican Fish-Eating Bat, Myotis vivesi

Authors: Edward Risto Hurme Published: 2020 Description: Foraging behavior is influenced by the distribution of prey in time and space and the presence of conspecifics. Echolocating bats, which advertise their behavior while vocalizing, provide a unique opportunity for understanding how an organism interacts with conspecifics and the environment to find food. Here I use GPS […]

Acoustic evaluation of behavioral states predicted from GPS tracking: a case study of a marine fishing bat

Authors: Edward Hurme, Eliezer Gurarie, Stefan Greif, L. Gerardo Herrera M., José Juan Flores-Martínez, Gerald S. Wilkinson, Yossi Yovel Publish Date: 14 June 2019 Description: Multiple methods have been developed to infer behavioral states from animal movement data, but rarely has their accuracy been assessed from independent evidence, especially for location data sampled with high […]

Echolocating bats can adjust sensory acquisition based on internal cues

Authors: Arjan Boonman, Itai Rieger, Eran Amichai, Stefan Greif, Ofri Eitan, Aya Goldshtein, Yossi Yovel Publish Date: 09 November 2020 Description: Sensory systems acquire both external and internal information to guide behavior. Adjustments based on external input are much better documented and understood than internal-based sensory adaptations. When external input is not available, idiothetic—internal—cues become […]

Mother bats facilitate pup navigation learning

Authors: Aya Goldshtein, Lee Harten, Yossi Yovel Date Published: 24 January 2022 Description: Goldshtein et al. document bats’ navigation ontogeny. Results suggest that mothers facilitate learning of navigation by repeatedly placing their pups on specific trees, which the pups later fly to on their first independent flights. Pups seem to learn navigation routes while being […]

Flight rapidly modulates body temperature in freely behaving bats

Authors: Jinhong Luo, Stefan Greif, Huan Ye, Sara Bumrungsri, Ofri Eitan & Yossi Yovel Publish Date: 03 November 2021 Description: Bats are remarkable in their dynamic control over body temperature, showing both hypothermia with torpor and hyperthermia during flight. Despite considerable research in understanding bats’ thermoregulation mechanisms, knowledge on the relationship between flight and body […]

Internet on animals: Wi-Fi-enabled devices provide a solution for big data transmission in biologging

Authors: Timm A. Wild,Martin Wikelski,Stephen Tyndel,Gustavo Alarcón-Nieto,Barbara C. Klump,Lucy M. Aplin,Mirko Meboldt,Hannah J. Williams Publish Date: 23 December 2021 Description: Biologging devices are deployed on animals to collect ultra-fine-scale movement data that reveal subsecond patterns in locomotion or long-term patterns in motion and space use. Often these two data types, although complementary, are rarely collected […]
