Seasonal variation in abundance and diversity of eavesdropping frog‐biting midges (Diptera, Corethrellidae) in a neotropical rainforest

We investigated the seasonal interaction among a specialized eavesdropping, frog-biting midges (Corethrella spp.), and their anuran hosts. Overall abundance of midges decreased in the dry season with little differences in abundance of species.

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

We investigate how signal synchronization is shaped by natural and sexual selection in two frog species. Our results show that synchronization reduces exposure to eavesdroppers and relaxed selection by females is likely important.

We show that male tree frogs reduce their attractiveness to eavesdropping enemies (bats and midges) by overlapping their calls at near-perfect synchrony with the calls of neighboring conspecifics taking advantage of an auditory illusion.

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

We investigated how the different call types of a Japanese stream breeding treefrog are affected by automobile traffic noise. This noise affected signal types in different ways suggesting some social functions will be disrupted more than others.

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

Complex color patterns can decrease capture of moving prey (motion dazzle effect). We found no support for the motion dazzle effect as striped crickets did not fare better than solid colored ones crickets that moved more were more likely to be eaten.

Laryngeal demasculinization in wild Cane Toads varies with land use

We examined wild populations of cane toads near sugarcane fields in Florida and found evidence of demasculinization in both primary and secondary sexual traits in male toads. Males from sugarcane areas have reduced larynges than toads from the city.

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

We examined call timing strategies of the Ryukyu Kajika frog showing variation in temporal signaling strategies within a species with a call type that is synchronized with neighbors and another one that is produced alternating.

We investigated two non-mutually exclusive hypotheses: 1) beacon effect and 2) eavesdropper avoidance. We found that synchronized signalling both increasing attraction of females to the chorus and reducing eavesdropper attacks.
