  • 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.

  • About the Book the Format Acknowledgments
    About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization.

    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.

  • 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.

Reptiles of Ecuador: a resource-rich online portal, with dynamic checklists and photographic guides 1Omar Torres-Carvajal, 2Gustavo Pazmiño-Otamendi, and 3David Salazar-Valenzuela 1,2Museo de Zoología, Escuela de Ciencias Biológicas, Pontifcia Universidad Católica del Ecuador, Avenida 12 de Octubre y Roca, Apartado 17- 01-2184, Quito, ECUADOR 3Centro de Investigación de la Biodiversidad y Cambio Climático (BioCamb) e Ingeniería en Biodiversidad y Recursos Genéticos, Facultad de Ciencias de Medio Ambiente, Universidad Tecnológica Indoamérica, Machala y Sabanilla EC170301, Quito, ECUADOR Abstract.—With 477 species of non-avian reptiles within an area of 283,561 km2, Ecuador has the highest density of reptile species richness among megadiverse countries in the world. 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.

COCHRAN Curator of Reptiles and Amphibians United States National Museum Publications of the United Slates National Museum The scientific publications of the United States National Museum include two series, Proceedings of the United States National Museum and United States National Museum Bulletin. In these series are published original articles and monographs dealing with the collections and work of the Museum and setting forth newly ac- quired facts in the fields of Anthropology, Biology, Geology, History, and Technology. Copies of each publication are distributed to libraries and scientific organizations and to specialists and others interested in the different subjects. The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers. These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume. In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related subjects. Bulletins are either octavo or quarto in size, depending on the needs of the presentation. Since 1902 papers relating to the botanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium. This work forms number 220 of the Bulletin series. Remington Kellogg, Director, United States National Museum.
