Impacts of the Australian Black Summer Fires on Bat Occupancy and Activity: The Role of Traits and Conservation Status

open access: yesAnimal Conservation, EarlyView.
The response of bats to Australian megafires was assessed one year after fires. High severity fire had a negative effect on total bat activity and the activity or occupancy of six species, while a further 10 species was not associated with any fire covariate. Overall, bat responses were complex and not easily predicted by traits alone.

Human exploration of enclosed spaces through echolocation [PDF]

open access: yes, 2017
Some blind humans have developed echolocation, as a method of navigation in space. Echolocation is a truly active sense because subjects analyze echoes of dedicated, self-generated sounds to assess space around them.

Evaluating social outcomes of urban bat citizen science: A case study of public knowledge, attitudes, and nature connectedness

open access: yesConservation Science and Practice, EarlyView.
Abstract Citizen science is widely used in biodiversity monitoring, yet its application to bats remains limited, particularly regarding how participation influences public understanding and support for conservation. This study examined short‐term changes in ecological knowledge, attitudes toward bats, and connection to nature following participation in

The jamming avoidance response in echolocating bats

open access: yesCommunicative & Integrative Biology, 2019
Bats face many sources of acoustic interference in their natural environments, including other bats and potential prey items that affect their ability to interpret the returning echoes of their biosonar signals.

Anatomical description of the jaw muscles and theoretical bite force assessment in South American opossums using manual and digital dissection methods

open access: yesJournal of Anatomy, EarlyView.
Manual and virtual dissections were employed to examine the masticatory muscle architecture and bite force of three South American marsupials. The organisation of the muscles differed between species, with predicted bite forces exceeding previous estimates.

From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

open access: yesJournal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

The Sonar Model for Humpback Whale Song Revised

open access: yesFrontiers in Psychology, 2018
Why do humpback whales sing? This paper considers the hypothesis that humpback whales may use song for long range sonar. Given the vocal and social behavior of humpback whales, in several cases it is not apparent how they monitor the movements of distant

Mixed‐vertebrate pollination traits and pollinators of Haageocereus acranthus (Cactaceae) in a lomas desert ecosystem of coastal Peru

open access: yesPlant Biology, EarlyView.
In a lomas desert ecosystem of coastal Peru, the columnar cactus Haageocereus acranthus shows traits and interactions consistent with a mixed‐vertebrate pollination system (hummingbirds and bats), with no detectable differences between flower colour morphotypes in either traits or interactions.

Correlated evolution between body size and echolocation in bats (order Chiroptera)

open access: yesBMC Ecology and Evolution
Background Body size and echolocation call frequencies are related in bats. However, it is unclear if this allometry applies to the entire clade. Differences have been suggested between nasal and oral emitting bats, as well as between some taxonomic ...

Managing Clutter in a High Pulse Rate Echolocation System

open access: yesFrontiers in Neuroscience, 2018
The use of echolocation for navigating in dense, cluttered environments is a challenge due to the need for rapid sampling of nearby objects in the face of delayed echoes from distant objects.
