Eastern spiny softshell turtles (Apalone spinifera) exhibit sexual size dimorphism (SSD) at maturity, and the much larger female body size is attributed to selection favouring greater reproductive output. Hatchlings exhibit sexually dimorphic markings, but hatchling SSD has not been investigated. The BIBH predicts that hatchlings will not exhibit SSD because reproductive benefits to larger, mature females drive size dimorphism at maturity, but selection on hatchlings relates only to survival. We tested this prediction with A. spinifera hatchlings (N = 2630) incubated in controlled conditions to avoid confounding environmental effects on phenotype. Hatchling mass was similar between sexes, suggesting similar nutritional allocation to male and female offspring. Hatchling size (carapace length) was also similar between sexes. Hatchling mass and body size varied among clutches and were positively related to maternal size, suggesting morphological constraints on egg size. Surprisingly, clutch size was related only weakly to maternal size. Taken together, our results suggest that hatchling size in A. spinifera is consistent with the BIBH and that offspring quality increases with maternal age, but that maternal effects drive a large proportion of the variation in clutch size and offspring quality.","PeriodicalId":55373,"journal":{"name":"Biological Journal of the Linnean Society","volume":"17 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139508438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested for barriers to pelagic dispersal across this peninsula for the commercially important blackspot snapper Lutjanus ehrenbergii using mitochondrial DNA sequences. We found scant evidence for population genetic differences when comparing within northern and southern sections, but instead found strong evidence of genetic differentiation between northern and southern sections, with the Persian/Arabian Gulf and Sea of Oman populations being highly differentiated from the Gulf of Aden and Red Sea populations. Low levels of haplotype sharing between the Persian/Arabian Gulf – Sea of Oman and the Gulf of Aden – Red Sea probably reflect scenarios of historical colonization into these peripheral bodies of water, or the presence of a contemporary ecological barrier preventing further genetic exchange.","PeriodicalId":55373,"journal":{"name":"Biological Journal of the Linnean Society","volume":"9 7","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139440360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we examined whether the ‘buzz’ vocalization in two species of Darwin’s finches, the small tree finch, Camarhynchus parvulus, and the critically endangered medium tree finch, C. pauper, found in Floreana Island, Galápagos Archipelago, is a signal of aggression. Specifically, we assessed three criteria for aggressive signalling (context, predictive, and response criteria) in an observational study and a playback experiment. In the observational study, buzzes by the resident male were more common when an intruder was present on the territory in medium tree finches but not small tree finches (context criterion). In the playback experiment, buzzes increased during and after a simulated intrusion for both species (context criterion). Buzzes before the playback period predicted aggressive responses by males (predictive criterion) but buzzes during playback did not. Finally, both species responded more strongly to playbacks of conspecific buzzes compared to conspecific songs and heterospecific buzzes (response criterion). Together the results support the aggressive signal hypothesis for buzz vocalizations, although future studies are needed to understand the evolution and development of this interesting signal.","PeriodicalId":55373,"journal":{"name":"Biological Journal of the Linnean Society","volume":"67 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139440977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Male signals (patch size and brightness) were quantified in Florida scrub lizards (Sceloporus woodi) from populations that vary in ectoparasite load. Males without mites were caught before breeding and exhibited different correlations among body size, patch size, and brightness. Males with ectoparasites (range = 1–368) were captured throughout the breeding season and showed a habitat-dependent pattern of how ectoparasite load, body size, and body condition were correlated with badge characteristics. In the sand pine scrub habitat, large males in good condition that were heavily parasitized had the largest badges. There was no relationship between body size or ectoparasite load and badge darkness. Lizards from longleaf pine habitat shared only one pattern, i.e. larger males had larger badges, yet there were several key differences. Body condition and ectoparasite load were unrelated to badge size, and the most heavily parasitized males had the brightest, not darkest, badges. Instead, males with moderate and low parasite loads had the darkest abdomens, and those with low parasite loads had the darkest throats. Thus, parasite load and body condition have habitat-dependent effects on badge characteristics.","PeriodicalId":55373,"journal":{"name":"Biological Journal of the Linnean Society","volume":"14 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139083453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In previous research, we reported a complex genetic structure within the Geranium yesoense complex, an alpine plant found in an interglacial refugium at high elevation in Central Japan, probably resulting from multiple colonization and hybridization events. However, we were unable to evaluate instances of introgression due to limited sample size. In the present study, we performed additional chloroplast genome sequencing, along with Sanger sequencing of selected chloroplast DNA regions, to elucidate the phylogenetic relationships among the refugial populations. The chloroplast genome sequence of a sample from Mt. Asama (an important refugium) was nested within the northern lineage (i.e. var. yesoense and var. pseudopratense), and haplotypes from Mt. Asama and Mt. Ibuki were also grouped with those of the northern lineage. Although our previous study suggested hybridization events between northern and southern lineages (i.e. var. nipponicum) at Mt. Asama, haplotypes from the southern lineage were not detected at range margins. This suggests that directional introgression occurred in these regions. Overall, our results further support that genetic heterogeneity within these refugia was amplified by recolonization and hybridization during past climate oscillations.","PeriodicalId":55373,"journal":{"name":"Biological Journal of the Linnean Society","volume":"21 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139083412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, there are four valid species of Trimerotropis in South America. However, some species were found to comprise several genetic lineages. Here, we describe the genetic structure, lineage diversification, and environmental requirements within the Trimerotropis species complex in South America based on sequences from the mitochondrial COI gene, 4048 single nucleotide polymorphisms, and ecological niche modelling. The analyses revealed the existence of at least five lineages: two with a restricted geographical distribution and three with a very wide one. The results provide evidence that glacial cycles promoted not only the presence of refuge areas but also the isolation of widely distributed lineages on the eastern and western sides of the southern Andes, potentially driving the emergence of the Trimerotropis sp. lineage, which can tolerate more temperate habitats.

Variation in whole-animal performance among mature individuals can become broadened by phenotypic plasticity driven by early life experiences. Thus, detailing the environmental factors that contribute to phenotypic plasticity, and the associated phenotypic responses governed by those environmental factors, is essential if we are to understand the evolution of whole-animal performance. Here, using isogenic lines established from the hermaphroditic mangrove rivulus fish (Kryptolebias marmoratus) housed in a ‘common garden’, we investigate the link between variation in adult terrestrial jumping performance and early life experience (i.e. egg density). First, we hypothesize that individuals from different isogenic lineages should vary in jumping performance independent of egg density, suggesting a strict genetic source of variation. Second, we hypothesize that phenotypic plasticity should also introduce variation in adult jumping performance. Specifically, we expect that hatchlings incubated at higher egg densities in early development should adopt better jumping performances as adults, because higher egg density might be a cue for greater intraspecific competition upon hatching.","PeriodicalId":55373,"journal":{"name":"Biological Journal of the Linnean Society","volume":"28 8","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138526328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
