Description: REVIEW Recent approaches to analyzing the evolution of female mating preferences emphasize how historical influences on female receiver systems can bias the evolution of male traits that females find attractive. These studies combine animal behavior, sensory biology, phylogenetics, and artificial neural network models. They attempt to understand why specific phenotypes involved in sexual selection have evolved, rather than merely determining whether such traits and preferences are adaptive. It is now clear that traits and preferences often do not coevolve via genetic correlations, that female mating preferences for a given male trait are influenced by adaptations and constraints outside of the context of female responses to that particular trait, and that receiver biases can explain much of the diversity in male signaling phenotypes. It also appears that an understanding of historical effects will prove valuable in investigating why neural and cognitive systems respond to sensory stimuli as they do.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ryan, M J -- New York, N.Y. -- Science. 1998 Sep 25;281(5385):1999-2003.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Texas, Austin, TX 78712, USA. mryan@mail.utexas.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9748154" target="_blank"〉PubMed〈/a〉

Description: Studies conducted in the field offer unique opportunities to observe nature, but achieving true replication under natural conditions is challenging. As demonstrated by the discovery of frog eating by a charismatic bat, biology conducted in the field generally follows an interesting progression that includes discovery, demonstration, experimentation, and verification.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ryan, Michael J -- New York, N.Y. -- Science. 2011 Dec 2;334(6060):1229-30. doi: 10.1126/science.1214532.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Integrative Biology, University of Texas, Austin, TX 78712, USA. mryan@mail.utexas.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22144615" target="_blank"〉PubMed〈/a〉

Description: Phylogenetic techniques were used to estimate and reconstruct advertisement calls at ancestral nodes. These calls were used to investigate the degree of preference of female tungara frogs (Physalaemus pustulosus) for both extant and ancestral calls. Females did not discriminate between calls of males of their own species and calls at their most recent ancestral node. They also recognized calls of three extant species and at four ancestral nodes as the signals of appropriate mates. Both shared ancestral history, and call convergence might differentially influence call preferences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ryan, M J -- Rand, A S -- New York, N.Y. -- Science. 1995 Jul 21;269(5222):390-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17841263" target="_blank"〉PubMed〈/a〉

Description: Female gynogens reproduce clonally but rely on sperm from heterospecific males to initiate embryogenesis. It has been assumed that males gain no benefit from such matings; thus, selection should favor males that avoid them. Here it is shown that males gain a benefit by mating with female gynogens in an asexual-sexual complex of fish. The sexual females increase their preference for males whom they observe consorting with female gynogens. Thus, gynogenetic species might persist because selection favors males to be sexually parasitized.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schlupp, I -- Marler, C -- Ryan, M J -- F32 MH10204/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 21;263(5145):373-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Texas, Austin 78712.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8278809" target="_blank"〉PubMed〈/a〉

Description: Mate recognition in frogs requires congruence of call characters, such as dominant frequency, and properties ofthe auditory system, such as frequency sensitivity of inner ear organs. Two neighboring populations of cricket frogs (Acri crepitans) exhibit statistically significant differences in the dominant frequency of the advertisement call and the frequency to which the basilar papilla of the inner ear is most sensitive. Call frequency and frequency sensitivity are matched within but differ between populations. These characters usually are negatively correlated with body size, and thus their congruence and coevolution often is explained by pleiotropic effects of size. However, within this species call frequency and frequency sensitivity ofthe basilar papilla evolved independent of body size, yielding local mate preferences that could contribute to genetic differentiation among neighboring populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ryan, M J -- New York, N.Y. -- Science. 1988 Jun 24;240(4860):1786.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17842431" target="_blank"〉PubMed〈/a〉

Description: Psychophysics measures the relationship between a stimulus's physical magnitude and its perceived magnitude. Because decisions are based on perception of stimuli, this relationship is critical to understanding decision-making. We tested whether psychophysical laws explain how female tungara frogs (Physalaemus pustulosus) and frog-eating bats (Trachops cirrhosus) compare male frog calls, and how this imposes selection on call evolution. Although both frogs and bats prefer more elaborate calls, they are less selective as call elaboration increases, because preference is based on stimulus ratios. Thus, as call elaboration increases, both relative attractiveness and relative predation risk decrease because of how receivers perceive and compare stimuli. Our data show that female cognition can limit the evolution of sexual signal elaboration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akre, Karin L -- Farris, Hamilton E -- Lea, Amanda M -- Page, Rachel A -- Ryan, Michael J -- P20 RR016816/RR/NCRR NIH HHS/ -- P20RR016816/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2011 Aug 5;333(6043):751-2. doi: 10.1126/science.1205623.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Integrative Biology, University of Texas, Austin, TX 78712, USA. kakre@mail.utexas.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21817052" target="_blank"〉PubMed〈/a〉

Description: Sexual signals are often complex and perceived by multiple senses. How animals integrate signal components across sensory modalities can influence signal evolution. Here we show that 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 tungara frogs. Such unanticipated perceptual effects suggest that the evolution of complex signals can occur by alteration of the relationships among already-existing traits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, R C -- Ryan, M J -- New York, N.Y. -- Science. 2013 Jul 19;341(6143):273-4. doi: 10.1126/science.1237113.

Description: Animal displays are often perceived by intended and unintended receivers in more than one sensory system. In addition, cues that are an incidental consequence of signal production can also be perceived by different receivers, even when the receivers use different sensory systems to perceive them. Here we show that the vocal responses of male tungara frogs (Physalaemus pustulosus) increase twofold when call-induced water ripples are added to the acoustic component of a rival's call. Hunting bats (Trachops cirrhosus) can echolocate this signal by-product and prefer to attack model frogs when ripples are added to the acoustic component of the call. This study illustrates how the perception of a signal by-product by intended and unintended receivers through different sensory systems generates both costs and benefits for the signaler.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halfwerk, W -- Jones, P L -- Taylor, R C -- Ryan, M J -- Page, R A -- New York, N.Y. -- Science. 2014 Jan 24;343(6169):413-6. doi: 10.1126/science.1244812.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Smithsonian Tropical Research Institute, Apartado 0843-03092, Balboa, Ancon, Republic of Panama.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24458640" target="_blank"〉PubMed〈/a〉

Description: Mate choice models derive from traditional microeconomic decision theory and assume that individuals maximize their Darwinian fitness by making economically rational decisions. Rational choices exhibit regularity, whereby the relative strength of preferences between options remains stable when additional options are presented. We tested female frogs with three simulated males who differed in relative call attractiveness and call rate. In binary choice tests, females' preferences favored stimulus caller B over caller A; however, with the addition of an inferior "decoy" C, females reversed their preferences and chose A over B. These results show that the relative valuation of mates is not independent of inferior alternatives in the choice set and therefore cannot be explained with the rational choice models currently used in sexual selection theory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lea, Amanda M -- Ryan, Michael J -- New York, N.Y. -- Science. 2015 Aug 28;349(6251):964-6. doi: 10.1126/science.aab2012.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Biology, The University of Texas, Austin, TX 78712, USA. alea@utexas.edu. ; Department of Integrative Biology, The University of Texas, Austin, TX 78712, USA.
