Item New records and distribution extension of Acanthochelys macrocephala (Rhodin, Mittermeier & McMorris 1984) in midwestern Brazil.(Cuad. herpetol., 2023) Dorado-Rodrigues, Tainá Figueras; Brito, Elizângela Silva; Silva, Karoline Rodrigues; Valadão, Rafael Martins; Cunha, Fábio Andrew Gomes; Strüssmann, ChristineItem Reptilia, Squamata, Amphisbaenidae, Amphisbaena brasiliana (Gray, 1865): range extension.(Herpetology Notes, 2013) Dorado-Rodrigues, Tainá Figueras; Strüssmann, Christine; Lima, Francco Antonio Neri de Souza e; Valadão, Rafael Martins; Motta, TamíAmphisbaena brasiliana is a Brazilian endemic amphisbaenid (Bérnils and Costa, 2012) described after a single specimen obtained in the municipality of Santarém, state of Pará (Gray, 1865: 448). Besides the type locality and vicinities (Gans, 1971; Spencer, 2012), thespecies is known from other three municipalities in the same state: Belém (Gans, 1971), Aveiro (Rio Cupari; Strauch, 1883) and Parauapebas (" Serra dos Carajás " ; Cunha et al., 1985). Two vouchered but imprecise additional records from localities along the " rio Amazonas " (Amazon River), and one undocumented record for Paraíba do Norte, state of Paraíba, were mentioned by Gans (1971), but this latter record was considered by that author as " questionable ". The species has also been found in Guarantã do Norte, extreme north of the state of Mato Grosso (Mott and Vieites, 2009; Pinna et al., 2010), the southernmost record until now. Herein we report three new municipality records for Amphisbaena brasiliana in the states of Pará and Mato Grosso which greatly extend the known distribution of this species. In addition, we provide data on habitats and a photo of a live specimen. Specimens were collected under IBAMA/SISBIO permits # 02001.000822/2008-71 and # 19518-1, and voucher specimens are deposited at Coleção Zoológica de Vertebrados, Universidade Federal de Mato Grosso (UFMT; Cuiabá, Mato Grosso, Brazil). Records accessed through the HerpNET (Spencer, 2012) data portal are held in the Museum of Comparative Zoology (Harvard University, Cambridge, Massachusetts, USA). In December 2006, a single individual of Amphisbaena brasiliana (UFMT 7785) was found in a semi-deciduous forest in the right margin of the reservoir of the hydroelectric power plant Cabeça de Boi, rio Cabeça de Boi, municipality of Alta Floresta, Mato Grosso (10º 19' S, 56º 58' W). In October 2009, another individual (UFMT 8477) was found in an alluvial semi-deciduous forest on the left margin of the reservoir of Herpetology Notes, volume 6: XXX-XXX (2013) (published online on XX Xxxx 2013)Item Diversity patterns of lizard assemblages from a protected habitat mosaic in the Brazilian Cerrado savanna(Journal of Tropical Ecology, 2022-05-16) Barros, Rafael Assis; Dorado-Rodrigues, Tainá Figueras; Valadão, Rafael Martins; Strüssmann, ChristineDifferences in habitat complexity and structure can directly influence the composition, diversity, and structure of species assemblages. Measurements of functional and phylogenetic diversity complement the commonly used measurements of taxonomic diversity, elucidating the relationships between species, their traits, and their evolutionary history. In this study, we evaluated how the mosaic of open and forested formations in a federal conservation unit in the western portion of the Brazilian Cerrado savanna influences the taxonomic, functional, and phylogenetic structure of lizard assemblages. Lizards were sampled for 15 months using pitfall traps set in open and forested formations. We recorded 292 lizards distributed among 16 species from eight families, with species composition differing among the formations. Richness was greater in the assemblages from open formations, while functional diversity and phylogenetic variability were greater in those of forested formations. Lizard assemblages in open formations were functionally and phylogenetically clustered, probably as a result of environmental filters acting on species, while the assemblages from forested formations were randomly structured. Different environmental and historical mechanisms have apparently shaped the current diversity of lizards in the region. This study shows that Cerrado vegetation mosaics can promote wide variation in different aspects of the taxonomic, functional, and phylogenetic structure from the lizard assemblages.
