Frommen","doi":"10.1007/s10682-023-10276-y","DOIUrl":"https://doi.org/10.1007/s10682-023-10276-y","url":null,"abstract":"Abstract Group living results in various benefits and costs, which often depend on group size and ontogenetic state of the individual. Therefore, certain group sizes are favourable over others, often depending on individual age or intrinsic state. Under natural conditions many amphibians can be found in aggregations, especially during the larval stage. Yet, whether these aggregations are the result of active social preferences or are driven by environmental factors has only been tested in a limited number of taxa. This study explores social preferences and group size discrimination in golden mantella ( Mantella aurantiaca ) tadpoles. We gave tadpoles the choice between different numbers of conspecifics using a two-choice design. To test for general social tendency, tadpoles could either join a group of three or remain solitary (3 vs. 0). To test for group size preferences, we tested tadpoles in two different ratios: 2 vs. 1 and 4 vs. 2 conspecifics. We repeated the trials weekly until metamorphosis to determine potential shifts in preference through ontogeny. Tadpoles preferred being with a group over being alone, and the strength of this preference declined with increasing age. Furthermore, tadpoles preferred to be close to the larger of two groups. This preference was stronger in the 2 vs. 1 treatment. Mantella aurantiaca tadpoles, therefore, show clear social tendencies and possess the ability to spontaneously discriminate between group sizes. The lower preference at higher group sizes might indicate cognitive limitations or lower benefits of choosing the larger of two groups when overall group size is high. These findings are one of the few showing social preferences depending on group size in tadpoles and contribute to our understanding of social behaviour in amphibians in general.","PeriodicalId":55158,"journal":{"name":"Evolutionary Ecology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136070270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Perception of con- and heterospecific injury cues in tadpoles of dendrobatid, ranid and bufonid frogs (Anura)","authors":"Konrad Lipkowski, Diana Abondano Almeida, Lisa Maria Schulte","doi":"10.1007/s10682-023-10275-z","DOIUrl":"https://doi.org/10.1007/s10682-023-10275-z","url":null,"abstract":"Abstract Predator-prey interactions are vital for organismal survival. They shape anti-predator mechanisms and often depend on sensory abilities. Tadpoles use chemical cues, such as injury cues (alarm cues), to assess predation risks and modify their life-history, morphology, and behaviours accordingly. However, the prevalence of chemically mediated anti-predator responses in species with distinct ecological niches (e.g. within phytotelmata) remains unknown, hindering our understanding of the ecological significance and evolution of alarm substances. Therefore, our study aimed to investigate chemically mediated anti-predator responses in tadpoles of two Neotropical poison dart frogs, Ranitomeya sirensis and Epipedobates anthonyi (and compare their responses to two Palearctic model organisms, Rana temporaria and Bufo bufo , which are known to utilise alarm substances). Through behavioural bioassays, we exposed predator-naïve tadpoles to extracts of each species (i.e. con- and heterospecific cues), including water as a control (i.e. five treatments per species). We assessed changes in their activity before and after stimulus introduction. Our results show that E. anthonyi did not respond to any of the stimuli, whereas R. sirensis displayed increased activity levels exclusively in response to conspecific cues, but not to heterospecific cues. With this, our findings suggest a specialized recognition system in R. sirensis , potentially directed at conspecific competitors but likely unrelated to anti-predator mechanisms. In contrast, E. anthonyi may be insensitive to injury cues or utilize alternative sensory modalities to respond to acute predation events. This study sheds light on the chemical alarm response system of Neotropical poison dart frog tadpoles, providing foundational understanding of how dendrobatids react to injury cues. It prompts questions about the ecological significance and evolutionary implications of chemical communication in species facing extreme resource limitation during development and underscores the importance of comparative research for understanding chemical communication in diverse aquatic ecosystems.","PeriodicalId":55158,"journal":{"name":"Evolutionary Ecology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136104328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jaime Zúñiga-Vega","doi":"10.1007/s10682-023-10270-4","DOIUrl":"https://doi.org/10.1007/s10682-023-10270-4","url":null,"abstract":"Abstract Placentotrophy is a particular type of maternal provisioning to developing embryos, in which mothers actively provide nutrients via complex placental structures. Placentotrophy implies less pre-fertilization investment, resulting in a shift from pre- to post-copulatory sexual selection. This change can potentially result in a conflict between females and males. This phenomenon has been demonstrated at the interspecific level in viviparous fishes of the family Poeciliidae, in which males of species that lack placentotrophy have evolved traits related to pre-copulatory sexual selection such as coloration, ornaments, and courtship behavior. Placentotrophic species, on the other hand, have evolved traits associated with post-copulatory sexual selection such as long intromittent organs (gonopodium) and increased sexual coercion behavior. Here we test, for the first time at the intraspecific level, whether there is a similar relationship between a higher degree of female placentotrophy and the evolution of male reproductive traits (larger testes and longer gonopodia) in three species of the genus Poeciliopsis ( P. gracilis , P. infans , and P. prolifica ). We observed a tendency towards longer gonopodia in males of P. gracilis as well as the largest testes of P. prolifica males in the populations with the highest degrees of placentotrophy. However, the statistical support for these findings was relatively weak. Therefore, we failed to support the hypothesis of a selective effect of female placentotrophy on male gonads and genitalia. We discuss other evolutionary forces that may have driven the observed intraspecific variation in male reproductive traits of Poeciliopsis fishes.","PeriodicalId":55158,"journal":{"name":"Evolutionary Ecology","volume":"14 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135510860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concession, restraint and tug-of-war skew models attempt to predict which social and ecological factors influence skew, whilst assuming different power dynamics and making contrasting predictions. The factors underpinning within-species variation in skew remain unclear, despite decades of research. Individuals vary in both the benefit of leaving the group to breed (outside option) and in the contribution they make to group productivity if they stay. Variation is likely among several aspects of individual quality, so that individuals and species may show different associations between the subordinate's outside option and group productivity. Yet, no existing skew models allow for variation in this association, here named the quality-productivity coefficient (QPC). If high subordinate quality is associated with being a good helper, for instance if both help and quality improve with age, the QPC would be positive. If, instead, there is a trade-off or other contrast between breeding ability and helping effect, then the QPC will be negative. Here, we incorporate the QPC and derive new predictions for the concession, restraint and tug-of-war models, that sometimes changed their predictions. We review the empirical tests of the association of skew with relatedness, dominant’s competitive advantage, group productivity and subordinate’s outside option. From 16 studies available to calculate an effect size, relatedness correlated positively with skew; yet overall most of 45 studies reported no association. The association of skew with the outside option was negative or null, fitting the restraint and tug-of-war models. The mostly non-significant effect of group productivity supported the three models. Our review highlights future fruitful avenues for the study of cooperative breeding, especially more work to assess the association between subordinate’s outside option and subordinate’s effect on group productivity.","PeriodicalId":55158,"journal":{"name":"Evolutionary Ecology","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135996090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
