Seasonal variation in abundance and diversity of eavesdropping frogā€biting midges (Diptera, Corethrellidae) in a neotropical rainforest

10.4231/E00F-VE65

Henry D Legett, Viktor Baranov, Ximena E Bernal

04/28/2021

In the tropics, precipitation patterns result in seasonal fluctuations in the abundance and distribution of plant and animal species. Tropical predators and parasites are therefore faced with seasonal changes in prey and host availability. This study inves...

Synchronized mating signals in a communication network: the challenge of avoiding predators while attracting mates

10.4231/SKRQ-CN44

Henry Legett, Rachel A Page, Ximena E Bernal

03/04/2021

Conspicuous mating signals attract mates but also expose signallers to predators and parasites. Signal evolution, therefore, is driven by conflicting selective pressures from multiple receivers, both target and non-target. Synchronization of mating signals...

Prey exploits the auditory illusions of eavesdropping predators

10.4231/TYHF-XJ20

Claire T Hemingway, Henry D Legett, Ximena E Bernal

03/04/2021

Mating signals have evolved to attract target receivers, even to the point of exploiting receivers through perceptual manipulation. Signals, however, can also expose signalers to nontarget receivers, including predators and parasites, and thus have also ev...

Traffic noise differentially impacts call types in a Japanese treefrog (Buergeria japonica)

10.4231/1GSD-PZ56

Henry Legett, Ikkyu Aihara, Ryan P. Madden, Ximena E Bernal

03/04/2021

Acoustic noise from automobile traffic impedes communication between signaling animals. To overcome the acoustic interference imposed by anthropogenic noise, species across taxa adjust their signaling behavior to increase signal saliency. As most of the sp...

Anuran predators overcome visual illusion: dazzle coloration does not protect moving prey

10.4231/KZT5-7E19

Geena M Darnell, Sara Zlotnik, Ximena E Bernal

04/06/2021

Predators everywhere impose strong selection pressures on the morphology and behavior of their prey, but the resulting antipredator adaptations vary greatly among species. Studies of adaptive coloration in prey species have generally focused on cryptic or...

Laryngeal demasculinization in wild Cane Toads varies with land use

10.4231/VWVS-M579

Marcos Gridi-Papp, Sara Zlotnik, Ximena E Bernal

03/04/2021

Anthropogenic factors, including the spread of endocrine-disrupting chemicals, have been linked to alterations in the reproductive physiology, morphology, and behavior of wildlife. Few studies of endocrine disruption, however, focus on secondary sexual tra...

Signal synchrony and alternation among neighbor males in a Japanese Stream Breeding Treefrog, Buergeria japonica

10.4231/7M5G-FZ96

Henry D Legett, Ikkyu Aihara, Ximena E Bernal

03/04/2021

Animals that aggregate in leks to attract mates often time the production of their mating signals against the signals of neighboring conspecifics. Such signal timing usually falls into general patterns within these aggregations, which can be categorized ba...

The dual benefits of synchronized mating signals in a Japanese treefrog

10.4231/J9RZ-QF79

Henry Legett, Ikkyu Aihara, Ximena E Bernal

03/04/2021

In dense mating aggregations, such as leks and choruses, acoustic signals produced by competing male conspecifics often overlap in time. When signals overlap at a fine temporal scale, either completely or partially, the ability of females to discriminate b...

Elucidating the history of anuran invasions: life history characteristics associated with range expansion in Florida

10.4231/72DB-ER33

Andrew Joseph Mularo, James Andrew DeWoody, Ximena E Bernal

04/12/2021

Invasive species pose serious ecological and economic threats to native biological systems. The temporal dynamics of invasions vary tremendously and are often difficult to characterize but can provide key insights into patterns of establishment and spread...

From mating to foraging: the evolution of eavesdropping in frog-biting mosquitoes

10.4231/FQ58-DC83

Bianca Rendon, Brian C Leavell, Gil Menda, Hoover Pantoja, Jian Zhou, Neil D. Sanscrainte, Ronald N Miles, Ronald R Hoy, W.A. Priyanka P. de-Silva, Ximena E Bernal

04/02/2021

While the origins of communication signals have long fascinated evolutionary biologists, our understanding of how selective pressures across contexts shape sensory systems is still limited. Most mosquito and midge species use hearing during acoustic mating...
