Book excerpt: Sexual selection and species-recognition are two different processes that can lead to behavioral reproductive isolation. The wolf spiders Schizocosa ocreata and S. rovneri are ethospecies which use distinct multi-modal courtship behavior, containing both visual and vibratory components, to maintain separation. Interspecific hybrids, which can be produced in the lab, perform a courtship display containing key multi-modal elements of both parental species. Without accounting for the multi-modal facets of courtship, laboratory experiments have found that male and female hybrids are behaviorally sterile when paired with either parental species (Stratton & Uetz, 1986). The present study isolates the cues necessary for species recognition in S. ocreata, S. rovneri, and hybrid females. Responses to heterospecific males (mate recognition errors) increase when S. ocreata and S. rovneri females are presented with only one communication mode from heterospecific males. When females are presented with hybrid males, however, results vary. Female S. ocreata and S. rovneri are receptive to hybrids in half of the trials when both primary and secondary cues are present, but show species differences in response across modes. Hybrid females respond less to all courting males, but show the highest receptivity to S. rovneri vibratory courtship. Analysis of the pattern of hybrid male behavior suggests that hybrid males behave in a manner more similar to the species typical behavior of their paternal parent. This study indicates that key species recognition elements are communicated in different sensory systems between the two spider species. These data suggest a potential for natural hybridization under conditions where one mode of communication is absent or constrained and raise questions about the importance of multiple modes of communication.
Download or read book Cognitive Cross modal Integration in a Wolf Spider Schizocosa Ocreata Hentz Lycosidae written by Elizabeth C. Kozak and published by . This book was released on 2015 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across animal species, males convey important information to potential mates through signals in multiple sensory modalities. In order to choose the best possible mate, female receivers must accurately perceive and assess male multimodal signals, especially when those signals occur simultaneously with those of other males. Cross-modal integration, i.e., cognitive binding of information transmitted in more than one sensory signal mode, is therefore important in animal communication, especially in complex, noisy environments in which many signals overlap. However, it is currently unknown how perception of multiple, disparate male signals plays a role in female mate choice decisions, especially for invertebrates. Males of the brush-legged wolf spider Schizocosa ocreata (Hentz) use multimodal communication (visual and vibratory signals) in courtship. Because female S. ocreata may be courted by multiple males at the same time, they must evaluate co-occurring male signals originating from separate locations. Moreover, due to environmental complexity, individual components of male signals may be occluded, altering detection of sensory modes by females. While experiments with live spiders and video playback have shown that female Schizocosa ocreata wolf spiders display receptivity to males courting in either isolated signal mode and show increased receptivity for multimodal courtship, it is unknown whether this is the case when females are presented with a choice between multimodal vs. isolated unimodal male courtship signals, and how these preferences are affected by disparity between signals. I first used digital multimodal playback to present females with a choice between 1) isolated unimodal (visuaI or vibratory), 2) multimodal vs. vibratory, and 3) multimodal vs. visual male courtship signals. I next used digital multimodal playback to investigate the effect of spatial and temporal disparity of visual and vibratory components of male courtship signals on female mate choice, and presented females with male courtship signals consisting of components that varied in spatial location or temporal synchrony. When presented with a choice between either isolated unimodal male courtship signal (visual or vibratory), there was no significant difference in the average number of receptive displays directed to either male signal. When presented with a choice between a multimodal male courtship signal and a vibratory male courtship signal, females directed, on average, significantly more receptive displays to the multimodal signal. However, when presented with a choice between multimodal and visual-only male courtship signals, there was no significant difference in receptivity directed by females to either signal, in contrast with the prediction generated from previous research. Females responded to spatially disparate signal components separated by e"90° as though they were separate sources, but responded to slightly disparate signals separated by d"45° as though they originated from a single source. Responses were seen as evidence for cross-modal integration. Temporal disparity (synchrony) in signal modes also affected female receptivity. Females responded more to male signals when visual and vibratory modes were in synchrony than either out-of-synch or interleaved/alternated. These findings are consistent with those seen in both humans and other vertebrates, and provide insight into how animals overcome communication challenges inherent in a complex environment.

Available in PDF, EPUB and Kindle. Book excerpt: Discover why animals do what they do, based on their genes, physiologies, cultures, traditions, survival and mating advantages, and evolutionary histories—and find out how studying behavior in the animal world helps us understand human behavior. The three volumes of Animal Behavior: How and Why Animals Do the Things They Do cover the breadth of the field, addressing causation, development, function, and evolution in a wide range of animals, from invertebrates to humans. Inspired by Nobel laureate Nikolaas Tinbergen's work, the first two volumes follow Tinbergen's four classic questions of animal behavior, while the third volume supplies integrated examples of Tinbergen's investigative process applied in specific cases. Written in an engaging, accessible manner ideal for college students as well as general audiences, this evidence-based collection provides a fascinating tour of animal behaviorists' findings, such as how animal communication can be truthful or deceitful, the deadly serious business behind clashes in the "battle of the sexes," and how documentation of animal behavior can lead to a deeper understanding of human behavior. Each chapter provides both historical background and information about current developments in animal behavior knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: A major new look at the evolution of mating decisions in organisms from protozoans to humans The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring. In Mate Choice, Gil Rosenthal overturns much of this conventional wisdom. Providing the first synthesis of the topic in more than three decades, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology, neuroscience, and economics, Rosenthal argues that "good genes" play a relatively minor role in shaping mate choice decisions and demonstrates how mate choice is influenced by genetic factors, environmental effects, and social interactions. Looking at diverse organisms, from protozoans to humans, Rosenthal explores how factors beyond the hunt for good genes combine to produce an endless array of preferences among species and individuals. He explains how mating decisions originate from structural constraints on perception and from nonsexual functions, and how single organisms benefit or lose from their choices. Both the origin of species and their fusion through hybridization are strongly influenced by direct selection on preferences in sexual and nonsexual contexts. Rosenthal broadens the traditional scope of mate choice research to encompass not just animal behavior and behavioral ecology but also neurobiology, the social sciences, and other areas. Focusing on mate choice mechanisms, rather than the traits they target, Mate Choice offers a groundbreaking perspective on the proximate and ultimate forces determining the evolutionary fate of species and populations.

The repeatability of female preference varied with the nature of the choice. Female preference for larger tufts was significant and repeatable (r = 0.65) when choosing between an average male and one with reduced tufts, but not when choosing between an average male and one with enlarged tufts. This may be an indication of a threshold trait. To examine variation in receptivity with age post-adulthood, I studied responses of females to a courting male video. Receptivity varied significantly with age post-adulthood: females were more aggressive and less receptive to video images of courting males in the first week, became significantly more receptive after 3 weeks, and less thereafter. Correlated changes in aggressive and receptivity behavior may suggest a physiological linkage. These studies demonstrate the importance of female focused dies of sexual selection, indicating that the female predominantly controls the mating system of S. ocreata wolf spiders.
