Acoustic shadows help gleaning bats find prey, but may be defeated by prey acoustic camouflage on rough surfaces

open access: yeseLife, 2015
Perceptual abilities of animals, like echolocating bats, are difficult to study because they challenge our understanding of non-visual senses. We used novel acoustic tomography to convert echoes into visual representations and compare these cues to ...

Pregnancy-related sensory deficits might impair foraging in echolocating bats

open access: yesBMC Biology, 2023
Background Reproduction entails substantial demands throughout its distinct stages. The mammalian gestation period imposes various energetic costs and movement deficits, but its effects on the sensory system are poorly understood.

Habitat heterogeneity and food availability in beaver‐engineered streams foster bat richness, activity and feeding

open access: yesJournal of Animal Ecology, EarlyView.
Beavers reshape ecosystems in ways that benefit bat richness, activity and feeding activity. We linked increased habitat structures (standing deadwood and canopy heterogeneity) and prey abundance to higher bat activity. Our findings uncover how beavers drive biodiversity across aquatic‐terrestrial boundaries.

Ranging in human sonar: effects of additional early reflections and exploratory head movements.

open access: yesPLoS ONE, 2014
Many blind people rely on echoes from self-produced sounds to assess their environment. It has been shown that human subjects can use echolocation for directional localization and orientation in a room, but echo-acoustic distance perception--e.g.

In situ novel environment assay reveals acoustic exploration as a repeatable behavioral response in migratory bats

open access: yesScientific Reports, 2021
Integrating information on species-specific sensory perception with spatial activity provides a high-resolution understanding of how animals explore environments, yet frequently used exploration assays commonly ignore sensory acquisition as a measure for

Severe Hearing Loss in the World's First Successfully Captive‐Born Yangtze Finless Porpoise: Impact of High Underwater Sound Exposure and Congenital Hearing Disorders

open access: yesIntegrative Zoology, EarlyView.
The audiogram of the world's first successfully captive‐born Yangtze finless porpoise was on average 40 dB higher than conspecifics. Congenital hearing disorders and noise exposure may be the primary cause of porpoise's hearing loss. ABSTRACT Aquariums globally have seen significant growth in recent decades.

Merleau-Ponty, World-Creating Blindness, and the Phenomenology of Non-Normate Bodies [PDF]

open access: yes, 2017
An increasing number of scholars at the intersection of feminist philosophy and critical disability studies have turned to Merleau-Ponty to develop phenomenologies of disability or of what, following Rosemarie Garland-Thomson, I call "non-normate ...

Spike Train Similarity Space (SSIMS) Method Detects Effects of Obstacle Proximity and Experience on Temporal Patterning of Bat Biosonar

open access: yesFrontiers in Behavioral Neuroscience, 2018
Bats emit biosonar pulses in complex temporal patterns that change to accommodate dynamic surroundings. Efforts to quantify these patterns have included analyses of inter-pulse intervals, sonar sound groups, and changes in individual signal parameters ...

Bat Tongues and Foraging: Linking Morphology to Hunting Strategies

open access: yesIntegrative Zoology, EarlyView.
We linked the bat tongue's mediodorsal lobe (MDL), a muscular prominence, to foraging strategies. Aerial hawkers exhibit tall MDLs and prominent forward‐pointing papillae. The MDL may function as a barrier or filter, preventing unintentional ingestion of non‐food material, aiding in prey handling, and controlling food access during fast flight ...
