Abstract Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action 1,2 . Ongoing developments in taxonomy, threatening processes and research further underscore the need reassessment 3,4 Here we report findings second Global Amphibian Assessment, evaluating 8,011 International Union Conservation Nature Red List Threatened Species. We find that amphibians most threatened vertebrate class (40.7% globally threatened). The updated...
We present a review and analysis of the conservation status International Union for Conservation Nature (IUCN) threat categories all 360 currently recognized species extant recently extinct turtles tortoises (Order Testudines). Our is based on 2018 IUCN Red List 251 listed species, augmented by provisional assessments Tortoise Freshwater Turtle Specialist Group (TFTSG) 109 unlisted freshwater turtles, as well re-assessments several outdated assessments. Of tortoises, this combined indicates...
Abstract Protected Areas (PAs) are the cornerstone of biodiversity conservation. Here, we collated distributional data for >14,000 (~70% of) species amphibians and reptiles (herpetofauna) to perform a global assessment conservation effectiveness PAs using distribution models. Our analyses reveal that >91% herpetofauna currently distributed in PAs, this proportion will remain unaltered under future climate change. Indeed, loss species’ ranges be lower inside than outside them....
Abstract Aim Temperature influences most components of animal ecology and life history – but what kind temperature? Physiologists usually examine the influence body temperatures, while biogeographers macroecologists tend to focus on environmental temperatures. We aim relationship between these two measures, determine factors that affect lizard temperatures test effect both temperature measures history. Location World‐wide. Methods used a large (861 species) global dataset mean annual across...
The island of Borneo lies within one the most biodiverse regions in world. Despite this, its documented gekkonid diversity is not commensurate with other areas Southeast Asia. megadiverse genus Cyrtodactylus especially underrepresented. Limestone-karst ecosystems, particular, harbor many endemic species, but only karst-dwelling species currently recognized from Borneo. This paper adds two additional species—C. muluensis sp. nov. and C. limajalur nov.—from Sarawak, Malaysia. to Gunung Mulu...
Abstract Aim Longevity is an important life‐history trait, directly linked to the core attributes of fitness (reproduction and survival), yet large‐scale comparative studies quantifying its implications for ecology life history ectotherms are scarce. We tested allometry longevity in squamates tuatara, determined how related key environmental characteristics traits. Predictions based on theory expected hold true ectotherms, similarly mammals birds. Location World‐wide. Methods assembled from...
Abstract Aim Small geographic ranges make species especially prone to extinction from anthropogenic disturbances or natural stochastic events. We assemble and analyse a comprehensive dataset of all the world's lizard identify with smallest ranges—those known only their type localities. compare them wide‐ranging infer whether specific regions biological traits predispose have small ranges. Location Global. Methods extensively surveyed museum collections, primary literature our own field...
A new species of the genus Tropidophorus is described from Putai, upper Baleh, Kapit districts, Sarawak, East Malaysia (Borneo). sebi sp. nov. diagnosable congeners Borneo by combination following characters: head shields present, dorsal and lateral scales smooth; parietal in two pairs; supraciliaries eight; supraoculars four; supralabials seven; infralabials postmental undivided; longitudinal scale rows 58; ventrals 53; transverse at midbody 34; subcaudals 98; preanals enlarged, single;...
A new species of frog belonging to the genus Polypedates Tschudi is described from state West Bengal, Eastern India. mid-sized frog, SVL ranges 47.9–53.6 mm in males and 72.0 single female. The diagnosable showing following suite characters: digits lack webbing, inner outer metacarpal tubercles present; no dermal fold on forearm; toes webbed, webbing formula I1–1 II0.5–2III1–2IV2–0.5V; an metatarsal tubercle tibio-tarsal articulation reaches between eye nostril; skin forehead co-ossified...
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed the Code has already been discussed Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; 2009a-b; Dubois Gentile Snell Minelli Cianferoni Bartolozzi 2016; Amorim et al. 2016). This was again raised a letter supported 35 signatories published journal Nature (Pape 2016) on 15 September 2016. On 25 2016,...
Abstract Aim Clutch size is a key life‐history trait. In lizards, it ranges over two orders of magnitude. The global drivers spatial and phylogenetic variation in clutch have been extensively studied birds, but such tests other organisms are lacking. To test the generality latitudinal gradients size, their putative drivers, we present first global‐scale analysis sizes across lizard taxa. Location Global. Time period Recent. Major taxa Lizards (Reptilia, Squamata, Sauria). Methods We analysed...
Abstract Aim Variation in body size across animal species underlies most ecological and evolutionary processes shaping local‐ large‐scale patterns of biodiversity. For well over a century, climatic factors have been regarded as primary sources natural selection on size, hypotheses such Bergmann's rule (the increase with decreasing temperature) dominated discussions. However, evidence for consistent effects, especially among ectotherms, remains equivocal. Here, we test range key...
Most new cryptic species are described using conventional tree- and distance-based delimitation methods (SDMs), which rely on phylogenetic arrangements measures of genetic divergence. However, although numerous factors such as population structure gene flow known to confound inference delimitation, the influence these processes is not frequently evaluated. Using large numbers exons, introns, ultraconserved elements obtained FrogCap sequence-capture protocol, we compared SDMs with more robust...
A new species of stream toad the genus Ansonia is described from Gunung Murud, Pulong Tau National Park, northern Sarawak, Malaysia, Borneo. vidua, sp. nov., morphologically distinguished its Bornean congeners by following combination characters: medium size (SVL adult females 33.5–34.4 mm); body uniformly black-brown in life; absence a visible pattern on dorsum or limbs; presence two low interorbital ridges; shagreened skin dorsum, sides and upper surfaces limbs with numerous homogeneously...

Abstract Aim Squamate fitness is affected by body temperature, which in turn influenced environmental temperatures and, many species, exposure to solar radiation. The biophysical drivers of temperature have been widely studied, but we lack an integrative synthesis actual experienced the field, and their relationships temperatures, across phylogeny, behaviour climate. Location Global (25 countries on six continents). Taxa Squamates (210 representing 25 families). Methods We measured 20,231...
We report the following seven species (representing five families) of true bugs (Hemiptera: Heteroptera) for first time from Arkansas: Hesperocorixa minor, Sigara virginiensis (Corixidae); Systelloderes biceps (Enicocephalidae); Hebrus buenoi (Hebridae): Empicoris winnemana, Ploiaria similis (Reduviidae); Microvelia fontinalis (Veliidae). This includes family Enicocephalidae (Unique-headed bugs) Arkansas. All were collected flight intercept traps (deployed April-July 2011) set in Arkansas...
