Sensory trait variation in an echolocating bat suggests roles for both selection and plasticity [PDF]

, 2014
Background: Across heterogeneous environments selection and gene flow interact to influence the rate and extent of adaptive trait evolution. This complex relationship is further influenced by the rarely considered role of phenotypic plasticity in the ...

Convergences in the diversification of bats

Current Zoology, 2010
Twenty-five characters or suites of characters from bats are considered in light of changes in bat classification. The characters include some associated with flower-visiting (two), echolocation (12), roosting (six), reproduction (two) and three are of ...

High Duty Cycle Echolocation May Constrain the Evolution of Diversity within Horseshoe Bats (Family: Rhinolophidae)

Diversity, 2018
The phenotype of organisms is the net result of various evolutionary forces acting upon their lineages over time. When an innovative trait arises that confers a substantial advantage in terms of survival and reproduction, the evolution of adaptive ...

Simulating the influences of bat curtailment on power production at wind energy facilities

Wildlife Society Bulletin, 2023
The development and expansion of wind energy is considered a key threat to bat populations in North America and globally. Several approaches to mitigating the impacts of wind energy development on bat populations have been developed, including curtailing

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Perceptual strategies in active and passive hearing of neotropical bats [PDF]

, 2008
Basic spectral and temporal sound properties, such as frequency content and timing, are evaluated by the auditory system to build an internal representation of the external world and to generate auditory guided behaviour. Using echolocating bats as model

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

Wildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

Shape Identification and Classification in Echolocation [PDF]

SIAM Journal on Imaging Sciences, 2014
The paper aims at proposing the first shape identification and classification algorithm in echolocation. The approach is based on first extracting geometric features from the reflected waves and then matching them with precomputed ones associated with a dictionary of targets.

Trackline and point detection probabilities for acoustic surveys of Cuvier’s and Blainville’s beaked whales [PDF]

, 2013
Acoustic survey methods can be used to estimate density and abundance using sounds produced by cetaceans and detected using hydrophones if the probability of detection can be estimated.

Niche occupancy of Jamaican bat caves: Diversity increases isotopic niche packing

Journal of Animal Ecology, EarlyView.
Tropical bat caves are home to hundreds of thousands of bats of multiple species. In Jamaica, we found that isotopic niche packing is the likely mechanism of coexistence at more diverse sites. Abstract There are over 1000 documented caves across Jamaica, many of them used by diverse communities of bats.
