Because evolution mostly acts over millions of years, the intermediate steps leading to a functional sensory system remain enigmatic. Accordingly, there is an ongoing debate regarding the evolution of bat echolocation. In search of the origin of bat echolocation, we studied how Old World fruit bats, which have always been classified as nonecholocating, orient in complete darkness. We found that two of these nonecholocating species used click-like sounds to detect and discriminate objects in… Expand
Bats Are Acoustically Attracted to Mutualistic Carnivorous Plants
TLDR
The results suggest that plants have convergently acquired reflectors in the Paleotropics and the Neotropics to acoustically attract bats, albeit for completely different ecological reasons. Expand
Opportunistic Use of Banana Flower Bracts by Glossophaga soricina
TLDR
These findings provide an example of an interaction between a plant and flower visitor not reflecting a shared evolutionary past and suggest that the bats use the echoes from the bract opportunistically as a cue to find the nectar source. Expand
Explosive radiation at the origin of Old World fruit bats (Chiroptera, Pteropodidae)
Pteropodidae constitutes one of the most diverse bat families. These bats have evolved a phytophagous diet, likely lost laryngeal echolocation capability, and attained the largest body sizes amongExpand
Bats regulate biosonar based on the availability of visual information
TLDR
How visual information, regulated by altering ambient light level, influences biosonar sampling by Egyptian fruit bats is examined, demonstrating how sensory information from one modality (vision) may influence sensory sampling of another (biosonar). Expand
Genomic and functional evidence reveals molecular insights into the origin of echolocation in whales
TLDR
Genetic and functional evidence is provided supporting the origin of high-frequency hearing in the LCATW, not the LCAW, and molecular insights are revealed into the origin and evolutionary trajectories of echolocation in whales. Expand
Auditory opportunity and visual constraint enabled the evolution of echolocation in bats
TLDR
It is shown that bats’ common ancestor had eyes too small to allow for successful aerial hawking of flying insects at night, but an auditory brain design sufficient to afford echolocation, and that non-echolocating, phytophagous pteropodid bats may retain some of the necessary foundations for biosonar. Expand
Predator–Prey Interactions: Co-evolution between Bats and Their Prey
TLDR
Co-evolution is defined as a process in which the evolution of traits in the predator is in direct response to the evolution in the prey which in turn evolved in directresponse to the traits of the predator and so on. Expand
Evolution and Ecology of Silent Flight in Owls and Other Flying Vertebrates
TLDR
It is hypothesized that bird flight is noisy because wing feathers are intrinsically predisposed to rub and make frictional noise, which implies that bats may be an overlooked model for silent flight. Expand
Bat Echolocation: Adaptations for Prey Detection and Capture
Bats have evolved a plethora of adaptations in response to the challenges of their diverse habitats and the physics of sound propagation. Such adaptations can confound investigations of adaptationsExpand
Integrating Ontogeny of Echolocation and Locomotion Gives Unique Insights into the Origin of Bats
TLDR
It is found clear evidence that the ability to hear high frequency echolocation-like sounds preceded the able to produce it and that a simple eCholocation system was likely inherited from a shrew-like ancestor and was not an in situ evolutionary innovation of bats. Expand

Click-based echolocation in bats: not so primitive after all
TLDR
It is suggested that click-based echolocation in bats should be regarded as a viable eCholocation strategy, which is in fact similar to the biosonar used by most e cholocating animals, including whales and dolphins. Expand
The evolution of echolocation in bats.
TLDR
The extensive adaptive radiation in echolocation call design is shaped largely by ecology, showing how perceptual challenges imposed by the environment can often override phylogenetic constraints. Expand
Echolocation in Oilbirds and swiftlets
TLDR
The advent of light-weight recording equipment and custom software for examining signals and reconstructing flight paths now provides the potential to study the echolocation behavior of birds in more detail and resolve ongoing discrepancies about several details. Expand
Primitive Early Eocene bat from Wyoming and the evolution of flight and echolocation
TLDR
A new bat is described from the Early Eocene Green River Formation of Wyoming, USA, with features that are more primitive than seen in any previously known bat, supporting a ‘flight first’ hypothesis for chiropteran evolution. Expand
Molecular evidence regarding the origin of echolocation and flight in bats
TLDR
A phylogenetic analysis of bat relationships using DNA sequence data from four nuclear genes and three mitochondrial genes indicates that microbat families in the superfamily Rhinolophoidea are more closely related to megabats than they are to other microbats, which implies that echolocation systems either evolved independently in rhinlophoids and otherMicrobat monophyly is uncorroborated by molecular data. Expand
Hearing in large (Eidolon helvum) and small (Cynopterus brachyotis) non-echolocating fruit bats
TLDR
Compared with all other bats tested so far, the typical high-frequency sensitivity of small non-echolocating mammals would have been sufficient to support initial echolocation in the early evolution of bats, a finding that supports the possibility of multiple origins of eCholocation. Expand
The hearing gene Prestin reunites echolocating bats
TLDR
The study of a hearing gene in bats strongly implicates Prestin in the evolution of echolocation, and suggests independent evolution of high-frequency hearing in bats, which highlights the potential problems of extracting phylogenetic signals from functional genes that may be prone to convergence. Expand
Echolocation intensity and directionality of perching and flying fringe-lipped bats, Trachops cirrhosus (Phyllostomidae)
TLDR
The data suggests that the limited search volume of T. cirrhosus sonar beam defined by the high directionality and the rather low intensity of its echolocation calls is adapted to the highly cluttered hunting habitat and to the perch hunting mode. Expand
A nuclear DNA phylogenetic perspective on the evolution of echolocation and historical biogeography of extant bats (chiroptera).
TLDR
195 morphological characters were evaluated and a morphological synapomorphy characterizing the Rhinolophoidea was identified and is suggestive of a separate origin of echolocation in this clade, as well as the center of origin of modern-day bat families. Expand
Convergent sequence evolution between echolocating bats and dolphins
TLDR
The Prestin gene has also undergone convergent amino acid substitutions in echolocating dolphins, which group with e cholocating bats in a phylogenetic tree of Prestin, and evidence is found that these changes were driven by natural selection. Expand
