An integrative view of the signaling phenotype: Dynamic links between signals, physiology, behavior and social context

Current Zoology, Journal Year: 2014, Volume and Issue: 60(6), P. 739 - 754

Abstract Signal traits are often linked with the physiological state and behavior of their bearer. Direct examination causal links among these variables has provided substantial insight into information content signals, costs benefits signal expression. Yet recent empirical work suggests that social context in which signals developed displayed can play a major role not only how received, but also coordinating mediating signaling phenotype itself. Here we review both well-established emerging evidence for direct feedbacks an individual’s state, behavior, elaboration. We then describe integrative view takes account bidirectional relationships components displayed. Integrating dynamic feedback between within models evolution maintenance may yield insights evolve, phenotypes coordinated maintained on ecological evolutionary time scales, static continue to convey relevant phenotypic about bearer through time.

Signal function drives phenotypic and genetic diversity: the effects of signalling individual identity, quality or behavioural strategy

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2017, Volume and Issue: 372(1724), P. 20160347 - 20160347

Animal coloration is influenced by selection pressures associated with communication. During communication, signallers display traits that inform receivers and modify receiver behaviour in ways benefit signallers. Here, we discuss how on to convey different kinds of information influences animal phenotypes genotypes. Specifically, address the phenotypic genetic consequences communicating three information: individual identity, behavioural strategy quality. Previous work has shown signals differ terms (i) type acting (e.g. directional, stabilizing, or negative frequency dependent), (ii) developmental basis (i.e. heritability, architecture). These differences result having consistently properties, including amount, modality continuity intraspecific variation. Understanding communication may allow researchers quickly identify putative functions colour variation prior experimentation. Signals will also have divergent evolutionary consequences. For example, signalling identity can increase diversity, quality decrease constrain adaptation contribute speciation. Considering recent advances genomic resources, our framework highlights new opportunities resolve across diverse taxa signal types.

Noise Affects Multimodal Communication During Courtship in a Marine Fish

Frontiers in Ecology and Evolution, Journal Year: 2018, Volume and Issue: 6

Selection pressures on signals can be substantially modified by a changing environment, but we know little about how selection act multimodal signals. The currently increasing levels of anthropogenic noise in the ocean may affect use acoustic signaling relative to other modalities. In Painted Goby (Pomatoschistus pictus), visual and are associated during courtship behavior, females usually rely more heavily than mate choice. an aquarium experiment, compared male behavior female spawning decisions between silent treatments with additional noise. We found that relationships characteristics, courtship, success were affected A path analysis revealed pay attention noisy circumstances control. conclude environmental stressors cause shifts different modalities for discuss change noise-levels.

Sex‐specific selection under environmental stress in seed beetles

Journal of Evolutionary Biology, Journal Year: 2016, Volume and Issue: 30(1), P. 161 - 173

Published: Oct. 17, 2016

Sexual selection can increase rates of adaptation by imposing strong in males, thereby allowing efficient purging the mutation load on population fitness at a low demographic cost. Indeed, sexual tends to be male-biased throughout animal kingdom, but little empirical work has explored ecological sensitivity this sex difference. In study, we generated theoretical predictions sex-specific strengths selection, environmental sensitivities and genotype-by-environment interactions tested them seed beetles manipulating either larval host plant or rearing temperature. Using fourteen isofemale lines, measured reductions components, strength (variance fitness) juvenile adult stage. As predicted, variance increased with stress, was consistently greater males than females for reproductive success (implying selection), similar sexes terms survival across all levels stress. Although genetic magnitude under severe heritability decreased particularly so males. Moreover, were common specific type life stage, suggesting that new environments may change relative alignment females. Our study thus exemplifies how stress influence forces natural as well concomitant changes fitness, which are predicted have consequences populations.

Poison frog color morphs express assortative mate preferences in allopatry but not sympatry

Evolution, Journal Year: 2016, Volume and Issue: 70(12), P. 2778 - 2788

Published: Oct. 12, 2016

The concurrent divergence of mating traits and preferences is necessary for the evolution reproductive isolation via sexual selection, such coevolution has been demonstrated in diverse lineages. However, extent to which assortative mate are sufficient drive nature less clear. Natural contact zones between lineages divergent provide exceptional opportunities testing predicted evolutionary consequences divergence. strawberry poison frog (Oophaga pumilio) displays extreme color polymorphism around young Bocas del Toro archipelago. In a transition zone red blue allopatric lineages, we asked whether female diverged along with coloration, any persist sympatry. When choosing among red, phenotypically intermediate males, females from monomorphic populations both expressed preferences. blue, all preferred suggesting that may be insufficient effect behavioral isolation. Our results highlight complexity isolation, need studies can reveal circumstances under do not contribute speciation.
