Many anuran amphibians are challenged with the detection of courtship signals in noisy chorus environments. Anurans and other animals partially solve this discrimination challenge by employing auditory mechanisms such as grouping sounds by frequency, time, or spatial location. Animals are also known to employ visual cues as a mechanism of improving auditory signal detection. In this study, we examined the effect of acoustic and visual stimuli on female mate choice preferences in the green tree… 
Multisensory modalities increase working memory for mating signals in a treefrog.
TLDR
It is demonstrated that a multimodal signal can engage longer working memory than a unimmodal signal, and thus female memory might favour the evolution of multimodAL signals in males through sexual selection.
Local preference encoded by complex signaling: mechanisms of mate preference in the red-eyed treefrog (Agalychnis callidryas)
TLDR
Choice tests with the Central American red-eyed treefrog found that both call and stripe are each sufficient to allow this nocturnal frog to choose mates in absence of the other stimulus, suggesting that call and color may encode both redundant information and multiple messages to receivers in this species.
Dueling frogs: do male green tree frogs (Hyla cinerea) eavesdrop on and assess nearby calling competitors?
TLDR
It appears males are able to alternate between assessment strategies dependent upon the frequency of the eavesdropped competition, and these findings indicate that males not only directly assess an opponent’s call in dyadic encounters, but also indirectly through eavesdropping.
Mate Searching Animals as Model Systems for Understanding Perceptual Grouping
TLDR
This chapter examines perceptual grouping in comparative models of mate choice behavior in frogs, and suggests that data from comparative models are not only useful for understanding signal processing in animal communication but also for potentially understanding the fundamental mechanisms receivers use to sort complex signals across all taxa and how such mechanisms may evolve.
Mate Preference Plasticity in a Critically Endangered Frog: Implications for Conservation Breeding
TLDR
Findings imply that female P. corroboree may become choosier over time, and highlight the potential for mate preferences to exhibit phenotypic plasticity within a single reproductive cycle, as well as suggesting that females are more attracted to low call frequencies after repeated exposure.
Limited effects of traffic noise on behavioural responses to conspecific mating calls in the eastern sedge frog Litoria fallax
TLDR
Female and male Litoria fallax frogs’ ability to distinguish between high- and low-quality acoustic signals during the presence of background traffic noise and without is investigated, finding that females in particular chose the unattractive call significantly more often when noise was being broadcast.
Communication and cooperation in wild chimpanzees(Pan troglodytes schweinfurthii)
TLDR
Examination of unimodal and multimodal communication in wild chimpanzees found that although MM signals were produced infrequently, and at lower rates compared to captivity, the vast majority of adult and sub-adult individuals did freely combine vocal, gestural and facial signals to produce MM signals.
Phenotypic integration and the evolution of signal repertoires: A case study of treefrog acoustic communication
TLDR
Methods from phenotypic integration studies were applied to quantify integration in the two primary vocalization types in the treefrogs Hyla versicolor, HylA cinerea, and Dendropsophus ebraccatus, finding significant integration across call types, but the strength of integration varied by species and corresponded with the acoustic similarity of the call types within each species.

Multimodal signaling in the Small Torrent Frog (Micrixalus saxicola) in a complex acoustic environment
TLDR
It is suggested that the vocal sac acts as a visual cue and improves detection and discrimination of acoustic signals by making them more salient to receivers amidst complex biotic background noise.
Female mate choice in the gray treefrog (Hyla versicolor) in three experimental environments
TLDR
It is suggested that the bias of females against both overlapped and very short calls may help explain why males lengthen their calls but lower their rate of delivery in response to increases in chorus size.
The Role of Visual Ornamentation in Female Choice of a Multimodal Male Courtship Display
TLDR
It is suggested that inexperienced females do not distinguish between males of different manipulated foreleg pigmentations in mate-choice decisions, even when in the presence of a seismic courtship signal.
Bimodal signal requisite for agonistic behavior in a dart-poison frog, Epipedobates femoralis
TLDR
It is reported that physical attacks by a territorial male are provoked only in response to dynamic bimodal stimuli in which the acoustic playback of vocalizations is coupled with vocal sac pulsations, but not by either unimodal cues presented in isolation or static bimmodal stimuli.
Female gray treefrogs, Hyla versicolor, are responsive to visual stimuli but unselective of stimulus characteristics
TLDR
It is argued that the female phototactic response has potentially significant behavioral implications and in general the consequences of anuran visual preferences deserve further investigation.
Interactions of Multisensory Components Perceptually Rescue Túngara Frog Mating Signals
TLDR
Two relatively unattractive signals that are perceived acoustically and visually can be combined in a pattern to form a signal that is attractive to female túngara frogs, suggesting that the evolution of complex signals can occur by alteration of the relationships among already-existing traits.
The importance of color in mate choice of the blue crab Callinectes sapidus
TLDR
It is shown that courtship and mate choice behavior in C. sapidus can be stimulated by visual cues alone, and that males have a preference for females with red claw dactyls, suggesting that blue crabs are capable of color vision and use color in mate choice.
Relative comparisons of call parameters enable auditory grouping in frogs.
TLDR
It is shown that for presentation of >2 call components, subjects are more likely to group the two components with the smallest relative differences in call parameters, including relative spatial separation and relative similarity to the species-specific call sequence.
