Walk near woods or water on any spring or summer night and you will hear a bewildering
(and sometimes deafening) chorus of frog, toad, and insect calls. How are these calls …

Chemically defended animals often display conspicuous color patterns that predators learn
to associate with their unprofitability and subsequently avoid. Such animals (ie, aposematic) …

Despite rising interest among scientists for over two centuries, parental care behavior has
not been as thoroughly studied in amphibians as it has in other taxa. The first reports of …

Animal acoustic signals play seminal roles in mate attraction and regulation of male spacing,
maintenance of pairbonds, localization of hosts by parasites, and feeding behavior. Among …

It is commonly assumed that natural selection imposed by predators is the prevailing force
driving the evolution of aposematic traits. Here, we demonstrate that aposematic signals are …

Aposematic signals may be subject to conflicting selective pressures from predators and
conspecifics. We studied female preferences for different components of aposematic …

Als junger Doktorand im ausgehenden letzten Jahrhundert war das Leben noch

Sex-role reversal occurs when females compete more intensely than males for access to
mates. In this paper, we survey the occurrence of sex-role reversal in vertebrates: we focus …

Social monogamy, typically characterized by the formation of a pair bond, increased
territorial defense, and often biparental care, has independently evolved multiple times in …
