Multi-National Conservation of Alligator Lizards
MULTI-NATIONAL CONSERVATION OF ALLIGATOR LIZARDS: APPLIED SOCIOECOLOGICAL LESSONS FROM A FLAGSHIP GROUP by ADAM G. CLAUSE (Under the Direction of John Maerz) ABSTRACT The Anthropocene is defined by unprecedented human influence on the biosphere. Integrative conservation recognizes this inextricable coupling of human and natural systems, and mobilizes multiple epistemologies to seek equitable, enduring solutions to complex socioecological issues. Although a central motivation of global conservation practice is to protect at-risk species, such organisms may be the subject of competing social perspectives that can impede robust interventions. Furthermore, imperiled species are often chronically understudied, which prevents the immediate application of data-driven quantitative modeling approaches in conservation decision making. Instead, real-world management goals are regularly prioritized on the basis of expert opinion. Here, I explore how an organismal natural history perspective, when grounded in a critique of established human judgements, can help resolve socioecological conflicts and contextualize perceived threats related to threatened species conservation and policy development. To achieve this, I leverage a multi-national system anchored by a diverse, enigmatic, and often endangered New World clade: alligator lizards. Using a threat analysis and status assessment, I show that one recent petition to list a California alligator lizard, Elgaria panamintina, under the US Endangered Species Act often contradicts the best available science. -

Paola María Sánchez Martínez Revisão Taxonômica da Tribo Dipsadini (Serpentes: Dipsadidae, Dipsadinae) São Paulo, Junho de 2016 Paola María Sánchez Martínez Revisão Taxonômica da Tribo Dipsadini (Serpentes: Dipsadidae, Dipsadinae) Tese apresentada ao Instituto de Biociências da Universidade de São Paulo para obtenção do título de Doutor em Ciências Biológicas Orientador: Dr. Hussam Zaher São Paulo, Junho de 2016 RESUMO A tribo Dipsadini é constituída pelos gêneros Dipsas, Plesiodipsas, Sibon, Sibynomorphus e Tropidodipsas, com 71 espécies válidas que se distribuem desde o México até o norte da Argentina. Os gêneros desta tribo de serpentes Neotropicais apresentam uma extensa variação nos padrões de coloração e na folidose, caracteres que são a base da sistemática deste grupo. Embora tenham sido publicados estudos taxonômicos recentes sobre algumas espécies e grupos de espécies dentro dos gêneros, a taxonomia desses tem se mostrado instável devido ao amplo uso de caracteres morfológicos que apresentam diversas formas intermediárias entre os padrões definidos e, que por sua vez,não são claros. Nesta revisão foram examinados cerca de 1600 exemplares, abrangendo a maioria das espécies da tribo e da sua distribução geográfica. A taxonomia de cinquenta dessas espécies foi avaliada, usando o padrão de coloração, morfologia hemipeniana e caracteres merísticos e morfométricos. As listas sinonímicas de todas as espécies da tribo foram elaboradas, clarificando o status taxonômico atual de cada uma, o que permitiu uma melhor definição taxonômica da tribo. Através desta análise foram reconhecidas 66 espécies válidas, um lectótipo foi designado, seis novas sinonímias foram propostas, cinco espécies foram revalidadas, e quatro espécies foram excluídas da tribo, justificando portanto a necessidade da descrição de dois genêros novos para posicioná-las. -

Due to its coral snake-like, bicolored pattern, the new species superfi- cially resembles Sibon anthracops, Dipsas articulata, D. bicolor, D. temporalis, and D. viguieri. It differs from these spe- cies, and from all its congeners, by having only five supralabials, by the unique shape of the posterior supralabial, and by a slight keeling on some dorsal rows in adults. We discuss its conservation perspectives, and provide new distributional records for S. annulatus and S. longifrenis, as well as an updated key to the Lower Central American species of Sibon. Key words: snail-eater, Dipsas, Chiriquí, Comarca Ngöbe-Buglé, Bocas del Toro, Veraguas, conservation, distribution extension, morphology Resumen Describimos Sibon noalamina sp. nov. de la vertiente Caribe de la Cordillera Central, Comarca Ngöbe-Buglé y provincia de Veraguas, en el occidente de Panamá. -

Similar to other eukaryotic genomes, large proportions of snake genomes contain repetitive DNA, including transposable elements (TEs) and satellite re- peats. The importance of repetitive DNA and its structural and functional role in the snake genome, remain unclear. This review highlights the major types of repeats and their proportions in snake genomes, reflecting the high diversity and composition of snake repeats. We present snakes as an emerging and important model system for the study of repetitive DNA under the impact of sex Citation: Ahmad, S.F.; Singchat, W.; and microchromosome evolution. -
Crotalus Tancitarensis. the Tancítaro Cross-Banded Mountain Rattlesnake
Crotalus tancitarensis. The Tancítaro cross-banded mountain rattlesnake is a small species (maximum recorded total length = 434 mm) known only from the upper elevations (3,220–3,225 m) of Cerro Tancítaro, the highest mountain in Michoacán, Mexico, where it inhabits pine-fir forest (Alvarado and Campbell 2004; Alvarado et al. 2007). Cerro Tancítaro lies in the western portion of the Transverse Volcanic Axis, which extends across Mexico from Jalisco to central Veracruz near the 20°N latitude. Its entire range is located within Parque Nacional Pico de Tancítaro (Campbell 2007), an area under threat from manmade fires, logging, avocado culture, and cattle raising. This attractive rattlesnake was described in 2004 by the senior author and Jonathan A. Campbell, and placed in the Crotalus intermedius group of Mexican montane rattlesnakes by Bryson et al. (2011). We calculated its EVS as 19, which is near the upper end of the high vulnerability category (see text for explanation), its IUCN status has been reported as Data Deficient (Campbell 2007), and this species is not listed by SEMARNAT. More information on the natural history and distribution of this species is available, however, which affects its conservation status (especially its IUCN status; Alvarado-Díaz et al. 2007). We consider C. tancitarensis one of the pre-eminent flagship reptile species for the state of Michoacán, and for Mexico in general. Photo by Javier Alvarado-Díaz. Amphib.

This richness is represented by 35 species of turtles, fve crocodilians, and 437 squamates including three amphisbaenians, 197 lizards, and 237 snakes. Of these, 45 species are endemic to the Galápagos Islands and 111 are mainland endemics. The high rate of species descriptions during recent decades, along with frequent taxonomic changes, has prevented printed checklists and books from maintaining a reasonably updated record of the species of reptiles from Ecuador. Here we present Reptiles del Ecuador (http://bioweb.bio/faunaweb/reptiliaweb), a free, resource-rich online portal with updated information on Ecuadorian reptiles. This interactive portal includes encyclopedic information on all species, multimedia presentations, distribution maps, habitat suitability models, and dynamic PDF guides. We also include an updated checklist with information on distribution, endemism, and conservation status, as well as a photographic guide to the reptiles from Ecuador. -

I developed novel methods for sampling the microbiomes of reptiles and summarized the current literature on non-mammalian gut microbiomes. In addition to establishing a standardized method of collecting and characterizing reptile microbiomes I made novel contributions to the future direction of the burgeoning field of host-associated microbiome research. -
