Extreme Miniaturization of a New Amniote Vertebrate and Insights Into the Evolution of Genital Size in Chameleons
www.nature.com/scientificreports OPEN Extreme miniaturization of a new amniote vertebrate and insights into the evolution of genital size in chameleons Frank Glaw1*, Jörn Köhler2, Oliver Hawlitschek3, Fanomezana M. Ratsoavina4, Andolalao Rakotoarison4, Mark D. Scherz5 & Miguel Vences6 Evolutionary reduction of adult body size (miniaturization) has profound consequences for organismal biology and is an important subject of evolutionary research. Based on two individuals we describe a new, extremely miniaturized chameleon, which may be the world’s smallest reptile species. The male holotype of Brookesia nana sp. nov. has a snout–vent length of 13.5 mm (total length 21.6 mm) and has large, apparently fully developed hemipenes, making it apparently the smallest mature male amniote ever recorded. The female paratype measures 19.2 mm snout–vent length (total length 28.9 mm) and a micro-CT scan revealed developing eggs in the body cavity, likewise indicating sexual maturity. The new chameleon is only known from a degraded montane rainforest in northern Madagascar and might be threatened by extinction. Molecular phylogenetic analyses place it as sister to B. karchei, the largest species in the clade of miniaturized Brookesia species, for which we resurrect Evoluticauda Angel, 1942 as subgenus name. The genetic divergence of B. nana sp. nov. is rather strong (9.9‒14.9% to all other Evoluticauda species in the 16S rRNA gene). A comparative study of genital length in Malagasy chameleons revealed a tendency for the smallest chameleons to have the relatively largest hemipenes, which might be a consequence of a reversed sexual size dimorphism with males substantially smaller than females in the smallest species. -

Reptiles and Amphibians of Otago
Society for Research on Amphibians and Reptiles in New Zealand (SRARNZ) presents Reptiles and Amphibians of Otago Otago is a large (31,251 km2) and lightly populated region of the southern South Island of Aotearoa New Zealand, stretching from the eastern coastline west to the Southern Alps. The earliest humans, of East Polynesian origin, arrived about 700 years ago. The largest settlement today is the coastal city of Dunedin (pop. >127,000), which grew from a Scottish influx in the 1800s. The Otago Regional Council administers the region, and tribal authority (mana whenua) rests with the iwi of Ngāi Tahu. Climates in the Otago region (roughly 45°– leiopelmatid frogs survive elsewhere in 47°S) range from changeable, cool- New Zealand. Two species of introduced temperate conditions near the coast to frogs are present, but there are no the near-continental climates (baking hot crocodilians, salamanders, terrestrial summers, freezing winters) of the interior. snakes or turtles.

Today’s herpetofauna is dominated by lizards (solely geckos and skinks), including about 10 described species. A further 12 or more undescribed taxa are recognised Otago by tag names for conservation purposes, and we follow that approach here. All lizards in Otago are viviparous and long- lived, and remain vulnerable to ongoing habitat loss and predation by introduced mammals. -
Ecology of Scree Skinks (Oligosoma Waimatense) in O Tu Wharekai Wetland, Mid-Canterbury High Country, New Zealand

RESEARCH Ecology of scree skinks (Oligosoma waimatense) in O Tu Wharekai Wetland, mid-Canterbury high country, New Zealand Marieke Lettink1* and Joanne M. Monks2 1Fauna Finders, 45 Park Terrace, Corsair Bay, Christchurch 8082 2Department of Conservation, Ōtepoti/Dunedin Office, PO Box 5244, Dunedin 9058 *Author for correspondence (Email: [email protected]) Published online: 17 October 2018 Abstract: Many of New Zealand’s 104 lizard taxa are restricted to the country’s main islands where they are vulnerable to a range of threats. Information on population trends and basic ecological data are lacking for most species, hampering conservation efforts. We monitored a population of scree skinks (Oligosoma waimatense; conservation status: Nationally Vulnerable) in an alluvial stream bed in O Tu Wharekai Wetland in the mid- Canterbury high country over 10 years (2008−2018) to understand aspects of the population’s ecology, and to clarify potential threats and options for management. Although there was no linear trend in scree skink capture numbers over this time, an 84% decline was observed following severe and unseasonal flooding in May 2009. Capture numbers recovered over c. 8.5 years in the absence of any species management. Skinks ranged in size from 60−114 mm (snout-to-vent length). Home range size estimates varied from 39.5 to 950 m2 (100% Minimum Convex Polygons) and their mean size was smaller than those reported for closely-related species. Photo-identification was not sufficiently accurate for long-term individual identification. -
Iguanidae: Hoplocercinae) from Southwestern Ecuador
Volume 48(20):227-235, 2008 A new species of ENYALIOIDES (Iguanidae: Hoplocercinae) from southwestern Ecuador Omar Torres-Carvajal1,2 Ana Almendáriz3 Jorge Valencia4 Mario Yánez-Muñoz5 Juan P. Reyes5 ABStract We describe a new species of Enyalioides from lowland cloud forests in southwestern Ecuador. This represents the third species in the genus known to occur west of the Andes in South America; the other two species are E. heterolepis and E. oshaughnessyi. Among other characters, the new species can be distinguished from other members in the genus by having small, keeled, paravertebrals; a series of skin folds on the lateral aspects of body and neck; size-homogeneous scales on body and limbs; distinct caudal segments; and an extensive dark patch on the gular region of adult males. Morphological similarity suggests that the new species, which we call E. touzeti, is closely related to E. oshaughnessyi. Keywords: Ecuador, Enyalioides, Hoplocercinae, Iguania, new species.

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. -

Us Caribbean Regional Coral Reef Fisheries Management Workshop
Caribbean Regional Workshop on Coral Reef Fisheries Management: Collaboration on Successful Management, Enforcement and Education Methods st September 30 - October 1 , 2002 Caribe Hilton Hotel San Juan, Puerto Rico Workshop Objective: The regional workshop allowed island resource managers, fisheries educators and enforcement personnel in Puerto Rico and the U.S. Virgin Islands to identify successful coral reef fishery management approaches. The workshop provided the U.S. Coral Reef Task Force with recommendations by local, regional and national stakeholders, to develop more effective and appropriate regional planning for coral reef fisheries conservation and sustainable use. The recommended priorities will assist Federal agencies to provide more directed grant and technical assistance to the U.S. Caribbean. Background: Coral reefs and associated habitats provide important commercial, recreational and subsistence fishery resources in the United States and around the world. Fishing also plays a central social and cultural role in many island communities. However, these fishery resources and the ecosystems that support them are under increasing threat from overfishing, recreational use, and developmental impacts. This workshop, held in conjunction with the U.S. Coral Reef Task Force Meeting, brought together island resource managers, fisheries educators and enforcement personnel to compare methods that have been successful, including regulations that have worked, effective enforcement, and education to reach people who can really effect change. These efforts were supported by Federal fishery managers and scientists, Puerto Rico Sea Grant, and drew on the experience of researchers working in the islands and Florida. The workshop helped develop approaches for effective fishery management strategies in the U.S. Caribbean and recommended priority actions to the U.S.
