Colobosauroides cearensis is a diurnal lizard with a relictual distribution associated with forested habitats in the Brazilian Caatinga Domain. Knowledge of the natural history of this secretive lizard is scarce. Herein, the diet, reproduction, sexual dimorphism, microhabitat use, and thermal ecology of C. cearensis are described based on fieldwork in 2015–2017 in the state of Ceará, Brazil. The diet of the lizards is composed exclusively of arthropods, with Formicidae being the most important prey category. Numerical and volumetric niche breadths are 5.52 and 9.2 respectively, and trophic niche overlap between females and males is 0.3. Males are distinguished from females by the larger size of the males and the presence of femoral pores. Colobosauroides cearensis is cryptozoic, inhabiting the leaf litter and having no direct contact with the soil or solar radiation. The average body temperature of the lizards is 30.4 ± 3.3°C, which is positively correlated with the air temperature. Gravid females with fixed clutch size of two eggs are found in early rainy season. Oviposition occurs between April and May (when the highest number of juveniles are observed). Sexual maturity occurs early in males and testicular volume is significantly correlated with body size.","PeriodicalId":48704,"journal":{"name":"Phyllomedusa","volume":"18 1","pages":"209-223"},"PeriodicalIF":0.4,"publicationDate":"2019-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.11606/issn.2316-9079.v18i2p209-223","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42592306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anuran species are considered generalist and opportunist feeders. However, some species have dietary specializations. Here we describe the diet composition of Rhinella proboscidea based on the stomach content of 29 individuals captured in terra frme forests in Manaus and São Sebastião do Uatumã, state of Amazonas, Brazil. Each prey item was measured and identifed to Order, Suborder or Family; ants were identifed to Genus. We determined and tested for differences in the trophic niche breadth and the relationships between the frog size and the volume of the largest prey item. We recorded 1614 prey items of 44 taxa. Hymenoptera was the most abundant Order followed by Isoptera, Acari, Coleoptera, Orthoptera, Araneae, Hemiptera, Dermaptera, Diptera, and Collembola. Formicidae comprised 46.56% of the all stomach items and was represented by six subfamilies and 22 genera. Additionally, we found 80 nematodes in a total of 18 frogs. There was a signifcant difference in the trophic niche breadths of the study areas, and a positive relationship between the toad size and volume of the largest prey item consumed. Rhinella proboscidea feeds on a variety of invertebrates, with ants, termites, and mites being the most abundant; this suggests that the toad is an active forager. The most common subfamily was Myrmicinae primarily represented by Crematogaster and Atta. Differences in trophic niche breadths of the study areas may be related to seasonal differences in the diet composition or local factors.","PeriodicalId":48704,"journal":{"name":"Phyllomedusa","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.11606/ISSN.2316-9079.V18I1P37-46","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45526298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dietary analysis is critical to understand the ecological roles of lizards, especially of species of Agama that are colonizing continents and islands from which they were previously absent. The foraging habits of four groups—viz., adult females, adult males, and young and juveniles (of both sexes)—of Agama agama in Nigeria were observed to assess the diet of the lizards and the contribution of the diet to separating age-sex classes. The claim that fying arthropods are less likely to be eaten by lizards was tested, and the hypothesis of dietary opportunism was explored. Sets (3–5 pellets) of 1453 fecal pellets collected during a 2-yr period were linked to individual lizards. Multivariate discriminant analysis of individual food items showed 61% lizards were correctly classifed to age-sex. However, items pooled into composite food groups, yielded fewer (43%) correctly classifed lizards. Cluster Analysis indicated that individual foods were less common (46.3%) to lizard classes than composite foods (76.1%). Thus, lizard age-sex classes are better differentiated when prey item is identifed at the lowest possible taxonomic level. Overall, arthropods are the largest, composite food for all lizard classes but, the relative amounts of different arthropod taxa varies signifcantly, and is highest for Diptera. Other foods include plants, seeds, and non-arthropod animal material. Differing coeffcients of variation accentuate dietary disparities within classes. Proportions of most individual and composite diet items differ signifcantly by month, season, and study site. Although consumed by lizards, no traces of white mold were found in the feces; this underscores the value of combining fecal analysis with surveillance of foraging habits of Agama agama.","PeriodicalId":48704,"journal":{"name":"Phyllomedusa","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.11606/issn.2316-9079.v18i1p63-75","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42286141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
