IUCN’s work focuses on valuing and conserving nature, ensuring effective and equitable governance of its use, and deploying nature-based solutions to global challenges in climate, food and development. IUCN supports scientific research, manages field projects all over the world, and brings governments, NGOs, the UN and companies together to develop policy, laws and best practice. IUCN is the world’s oldest and largest global environmental organization, with more than 1,200 government and NGO Members and almost 11,000 volunteer experts in some 160 countries. IUCN’s work is supported by over 1,000 staff in 45 offices and hundreds of partners in public, NGO and private sectors around the world. For more infor- mation about IUCN, visit <www.iucn.org>. The Species Survival Commission (SSC) is one of six volunteer commissions of IUCN. SSC’s mission is to conserve biological diversity by developing and executing programs to save, restore and wisely manage species and their habitats. The Amphibian Specialist Group (ASG) provides the scientific foundation to inform effective amphibian conservation action around the world. More specifically, the ASG stimulates, develops and conducts scientific research to inform the conser- vation of amphibians and their habitats around the world, supports the assessment of the conservation status of amphibian biodiversity and informs the general public of amphibian conservation-related issues and priorities. This is attained by sup- porting and mobilizing a global network of members to develop capacity, improve coordination and integration so as to achieve shared, strategic amphibian conserva- tion goals.

  • Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
    Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

  • Nototriton Nelsoni Is a Moss Salamander Endemic to Cloud Forest in Refugio De Vida Silvestre Texíguat, Located in the Departments of Atlántida and Yoro, Honduras
    Nototriton nelsoni is a moss salamander endemic to cloud forest in Refugio de Vida Silvestre Texíguat, located in the departments of Atlántida and Yoro, Honduras. This cryptic species long was confused with N. barbouri, a morphologically similar species now considered endemic to the Sierra de Sulaco in the southern part of the department of Yoro. Like many of its congeners, N. nelsoni rarely is observed in the wild, and is known from just five specimens. Pictured here is the holotype of N. nelsoni, collected above La Liberación in Refugio de Vida Silvestre Texíguat at an elevation of 1,420 m. This salamander is one of many herpetofaunal species endemic to the Cordillera Nombre de Dios. ' © Josiah H.

E-mail: [email protected] ABSTRACT: The Cordillera Nombre de Dios is a chain of mountains along the northern coast of Honduras that harbors a high degree of herpetofaunal endemism. We present a preliminary barcode reference library of amphibians from the Cordillera Nombre de Dios, based on sampling at 10 sites from 2008 to 2013. We sequenced 187 samples of 21 nominal taxa for the barcoding locus cytochrome oxidase subunit I (COI), and recovered 28 well-differentiated clades.

  • 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.

Kirk2 1 Jena Microbial Resource Collection, Institute of Microbiology, University of Jena, Neugasse 25, 07743 Jena, Germany 2 CABI UK Centre, Bakeham Lane, Egham, Surrey TW20 9TY, United Kingdom *Correspondence to: Hoff[email protected] Abstract — TheMucoromycotina unifies two heterogenous orders of the sporangiferous, soil- inhabiting fungi. The Mucorales comprise saprobic, occasionally facultatively mycoparasitic, taxa bearing a columella, whereas the Mortierellales encompass mainly saprobic fungi lacking a columella. Multi-locus phylogenetic analyses based on eight nuclear genes encoding 18S and 28S rRNA, actin, alpha and beta tubulin, translation elongation factor 1alpha, and RNA polymerase II subunits 1 and 2 provide strong support for separation of the Mortierellales from the Mucoromycotina. The existence of a columella is shown to serve as a synapomorphic morphological trait unique to Mucorales, supporting the taxonomic separation of the acolumellate Mortierellales from the columellate Mucoromycotina. Furthermore, irregular hyphal septation and development of subbasally vesiculate sporangiophores bearing single terminal sporangia strongly correlate with the phylogenetic delimitation of Mortierellales, supporting a new subphylum, Mortierellomycotina. Key words — Zygomycetes, SSU rDNA, LSU rDNA, protein-coding genes, monophyly Introduction The type species ofMortierella Coem. 1863, M. polycephala Coem. 1863, was originally isolated from a parasitic interaction with a mushroom and named in honour of M. Du Mortier, the president of the Société de Botanique de Belgique (Coemans 1863). However, the common habit of mortierellalean species is as soil saprobes, enabling the fungi to grow on excrements, decaying plants, or (not infrequently) on decaying mushrooms and mucoralean fungi (Fischer 1892).
