We combined three sampling meth- ods: large plots, transects and pit-fall traps. We recorded 12 frog species associ- ated with forest leaf-litter: Adenomera marmorata Steindachmer 1867, Leptodac- tylus ocellatus (Linnaeus 1758), and Physalaemus signifer (Girard 185) (Lepto- dactylidae); Eleutherodactylus binotatus (Spix 1824), E. guentheri (Steindachmer 1864), E. octavioi Bokermann 1965, and Euparkerella cochranae Izechsohn 1988 (Brachycephalidae); Proceratophrys boiei (Wied-Neuwied 1821) (Cycloramphi- dae); Chaunus ornatus Spix 1824 and Chaunus ictericus Spix 1824 (Bufonidae); Chiasmocleis carvalhoi Cruz et al. 1997 (Microhylidae); and Scinax aff. x-signatus (Spix 1824) (Hylidae). The area had a relatively high overall density (8.4 ind/100 m2) of leaf-litter frogs compared to other Atlantic forest areas. -
Diversity of Hemipenes and Its Taxonomical Implication in the Genus Ablepharus (Squamata: Scincidae)
ARPHA Conference Abstracts 2: e39487 doi: 10.3897/aca.2.e39487 Conference Abstract Diversity of hemipenes and its taxonomical implication in the genus Ablepharus (Squamata: Scincidae) Vladislav Vergilov‡, Georgi Popgeorgiev‡§, Boyan Zlatkov ‡ National Museum of Natural History, Bulgarian Academy of Sciences, Sofia, Bulgaria § Institute of Biodiversity and Ecosystem Research, Bulgarian Academy of Sciences, Sofia, Bulgaria Corresponding author: Vladislav Vergilov ([email protected]) Received: 27 Aug 2019 | Published: 28 Aug 2019 Citation: Vergilov V, Popgeorgiev G, Zlatkov B (2019) Diversity of hemipenes and its taxonomical implication in the genus Ablepharus(Squamata: Scincidae). ARPHA Conference Abstracts 2: e39487. https://doi.org/10.3897/aca.2.e39487 Abstract The genus Ablepharus encompasses 10 species and 12 subspecies, distributed from Hungary to India. Most species and subspecies have been described from the Middle East and Central Asia, based on external morphology (pholidosis, body size and coloration). The present study is an attempt to demonstrate the hemipenial morphology throughout the genus. Some taxonomical questions arose during comparison of the hemipenes of several subspecies and species, showing the necessity of a revision of the genus. A dendrogram generated from distinctive hemipenial characters revealed rapid divergence of this structure in closely related taxa and discrepancy with the phylogenetic tree based on molecular data from previous studies.

Most importantly, you gave me the freedom to work on questions that I’m passionate about. You never stopped challenging me and always asked that I push a little bit farther. I really think your commitment to scientific rigor goes above and beyond the average. And thank you for the many, many cups of tea over the years. My committee members, Dr. Scott Findlay and Dr. Mark Forbes, your feedback made this a better thesis. Scott, thank you for being scary enough to motivate me to always bring my A-game, and for providing endless new words to look up in the dictionary. By the end of this, I may actually know what ‘epistemological’ means. I would also like to thank Dr. Jeremy Kerr for his insight and not being afraid to be a scientist and an advocate. I need to thank all the lab mates that have come and gone and added so much to the last six years. -
Stream Frogs, Mannophryne Trinitatis (Dendrobatidae): an Example of Anti-Predator Behaviour
HERPETOLOGICAL JOURNAL, Vol. 11, pp. 91-100 (2001) SELECTION OF TAD POLE DEPOSITION SITES BY MALE TRINIDADIAN STREAM FROGS, MANNOPHRYNE TRINITATIS (DENDROBATIDAE): AN EXAMPLE OF ANTI-PREDATOR BEHAVIOUR J. R. DOWNIE, S. R. LIVINGSTONE AND J. R. CORMACK Division of Environmental and Evolutionary Biology, Institute of Biomedical & Life Sciences, University of Glasgow, Scotland, UK Trinidad's only dendrobatid frog, Mannophryne (=Colostethus) trinitatis, lives by the small streams draining the slopes of the Northern Range mountains and at Tamana Hill in the Central Range. Adults are often very abundant, but tadpoles are found patchily in the streams. In the absence of two potential predators - the fish Rivulus hartii and shrimps of the genus Macrobrachium - tadpoles are abundant in pools. Where the predators are present, tadpoles are uncommon or absent. Tadpoles may also be found in small, isolated bodies of water at some distance from streams. Males carrying tadpoles retained them for 3-4 days, in the absence of suitable pools. When presented with a choice of pools, males preferred to deposit their tadpoles in pools lacking predators. There were differences in behaviour between males fromthe northern and southern slopes of the Northern Range. For example, north coast males deposited tadpoles in pools containing other conspecific tadpoles in preference to empty pools, whereas males from southern slopes made the opposite choice. When presented only with pools containing predators (i.e. shrimps or fish), north coast males shed their tadpoles in damp leaf litter rather than in the pools, while males from the southern slopes deposited tadpoles in pools with shrimps - predators uncommon in the southern slopes streams. -

Tolosa et al. Actual Biol Volumen 37 / Número 102, 2014 Sexual maturity and sexual dimorphism in a population of the rocket-frog Colostethus aff. fraterdanieli (Anura: Dendrobatidae) on the northeastern Cordillera Central of Colombia Madurez y dimorfismo sexual de la ranita cohete Colostethus aff. fraterdanieli (Anura: Dendrobatidae) en una población al este de la Cordillera Central de Colombia Yeison Tolosa1, 2, *, Claudia Molina-Zuluaga1, 4,*, Adriana Restrepo1, 5, Juan M. Daza1, ** Abstract The minimum size of sexual maturity and sexual dimorphism are important life history traits useful to study and understand the population dynamics of any species. In this study, we determined the minimum size at sexual maturity and the existence of sexual dimorphism in a population of the rocket-frog, Colostethus aff. fraterdanieli, by means of morphological and morphometric data and macro and microscopic observation of the gonads. Females attained sexual maturity at 17.90 ± 0.1 mm snout-vent length (SVL), while males attained sexual maturity at 16.13 ± 0.06 mm SVL. Females differed from males in size, shape and throat coloration. Males were smaller than females and had a marked and dark throat coloration that sometimes extended to the chest, while females lacked this characteristic, with a throat either immaculate or weakly pigmented. In this study, we describe some important aspects of the reproductive ecology of a population of C. aff. fraterdanieli useful as a baseline for other more specialized studies. Key words: Amphibian, Andes, gonads, histology, morphometry, reproduction Resumen El tamaño mínimo de madurez sexual y el dimorfismo sexual son importantes características de historia de vida, útiles para estudiar y comprender la dinámica poblacional de cualquier especie. -

Box 45553, Abu Dhabi, United Arab Emirates, e-mail: [email protected] 2Natural Science and Public Health, College of Arts and Sciences, Zayed University, P.O. Box 4783, Abu Dhabi, United Arab Emirates Abstract.—This paper provides an updated checklist of the United Arab Emirates (UAE) native and alien herpetofauna. The UAE, while largely a desert country with a hyper-arid climate, also has a range of more mesic habitats such as islands, mountains, and wadis. As such it has a diverse native herpetofauna of at least 72 species as follows: two amphibian species (Bufonidae), five marine turtle species (Cheloniidae [four] and Dermochelyidae [one]), 42 lizard species (Agamidae [six], Gekkonidae [19], Lacertidae [10], Scincidae [six], and Varanidae [one]), a single amphisbaenian, and 22 snake species (Leptotyphlopidae [one], Boidae [one], Colubridae [seven], Hydrophiidae [nine], and Viperidae [four]). Additionally, we recorded at least eight alien species, although only the Brahminy Blind Snake (Ramphotyplops braminus) appears to have become naturalized. We also list legislation and international conventions pertinent to the herpetofauna.

Amphibians from the Centro Marista São José Das Paineiras, in Mendes, and Surrounding Municipalities, State of Rio De Janeiro, Brazil
Herpetology Notes, volume 7: 489-499 (2014) (published online on 25 August 2014) Amphibians from the Centro Marista São José das Paineiras, in Mendes, and surrounding municipalities, State of Rio de Janeiro, Brazil Manuella Folly¹ *, Juliana Kirchmeyer¹, Marcia dos Reis Gomes¹, Fabio Hepp², Joice Ruggeri¹, Cyro de Luna- Dias¹, Andressa M. Bezerra¹, Lucas C. Amaral¹ and Sergio P. de Carvalho-e-Silva¹ Abstract. The amphibian fauna of Brazil is one of the richest in the world, however, there is a lack of information on its diversity and distribution. More studies are necessary to increase our understanding of amphibian ecology, microhabitat choice and use, and distribution of species along an area, thereby facilitating actions for its management and conservation. Herein, we present a list of the amphibians found in one remnant area of Atlantic Forest, at Centro Marista São José das Paineiras and surroundings. Fifty-one amphibian species belonging to twenty-five genera and eleven families were recorded: Anura - Aromobatidae (one species), Brachycephalidae (six species), Bufonidae (three species), Craugastoridae (one species), Cycloramphidae (three species), Hylidae (twenty-four species), Hylodidae (two species), Leptodactylidae (six species), Microhylidae (two species), Odontophrynidae (two species); and Gymnophiona - Siphonopidae (one species). Visits to herpetological collections were responsible for 16 species of the previous list. The most abundant species recorded in the field were Crossodactylus gaudichaudii, Hypsiboas faber, and Ischnocnema parva, whereas the species Chiasmocleis lacrimae was recorded only once. Keywords: Anura, Atlantic Forest, Biodiversity, Gymnophiona, Inventory, Check List. Introduction characteristics. The largest fragment of Atlantic Forest is located in the Serra do Mar mountain range, extending The Atlantic Forest extends along a great part of from the coast of São Paulo to the coast of Rio de Janeiro the Brazilian coast (Bergallo et al., 2000), formerly (Ribeiro et al., 2009). -
