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. -

Veiled Chameleon
Husbandry Guidelines for Veiled Chameleon Chamaeleo calyptratus (Reptilia: Chamaeleonidae) DUMÉRIL & DUMÉRIL 1851 Date By From Version 2015 Stuart Daniel WSI Richmond v 1 OCCUPATIONAL HEALTH AND SAFETY RISKS This species, veiled chameleon (Chamaeleo calyptratus), is classed as an innocuous animal and poses minimal to no risk to keepers. The veiled chameleon is a small, generally non-aggressive species which possesses no anatomical features that could cause any harm. Though it is common for individuals of this species to be reluctant toward handling, any action performed to avoid being handled is generally for display only and will not result in any physical aggression. Individuals that feel threatened will put on a threat display which involves an open mouth and extension of the throat pouch (see figure). On the odd occasion an individual may bite but it is very rare that this will break the skin or cause any discomfort at all. Working with any animal species poses a risk of zoonotic disease. Common zoonotic diseases are listed in the table below, as well as other potential hazards that may be present in the work environment. Potential hazards of working with veiled chameleons and in the work environment in general Physical Injury from manual handling Falls from ladders if enclosures are above head height Slips/trips over cluttered workspace or wet floor Chemical Injury or poisoning from misuse of chemicals -F10 veterinary disinfectant -Bleach -Medications Biological Zoonosis – Salmonella spp, Campylobacter spp, Klebsiella spp, Enterobacter -

REPRODUCTION IN DWARF CHAMELEONS (BRADYPODION) WITH PARTICULAR REFERENCE TO B. PUMILUM OCCURRING IN FIRE-PRONE FYNBOS HABITAT JENNIFER C. JACKSON Dissertation presented for the degree of Doctor of Philosophy (Zoology) at the University of Stellenbosch Supervisor: Prof. P le F. N. Mouton Co-supervisor: Dr. A. F. Flemming December 2007 Stellenbosch University http://scholar.sun.ac.za DECLARATION I, the undersigned, hereby declare that the work contained in this thesis is my own original work and that I have not previously in its entirety or in part been submitted it at any university for a degree. ………………………………. ……………… Signature Date Copyright © 2007 Stellenbosch University All rights reserved II Stellenbosch University http://scholar.sun.ac.za ABSTRACT South Africa, Lesotho and Swaziland are home to an endemic group of dwarf chameleons (Bradypodion). They are small, viviparous, insectivorous, arboreal lizards, found in a variety of vegetation types and climatic conditions. Previous work on Bradypodion pumilum suggests prolonged breeding and high fecundity which is very unusual for a viviparous lizard inhabiting a Mediterranean environment. It has been suggested that the alleged prolonged reproduction observed in B. pumilum may be a reproductive adaptation to life in a fire-prone habitat. In addition, Chamaesaura anguina a viviparous, arboreal grass lizard also occurs in the fire-frequent fynbos and exhibits an aseasonal female reproductive cycle with high clutch sizes; highly unusual for the Cordylidae. With the observation of two species both inhabiting a fire-driven environment and exhibiting aseasonal reproductive cycles with high fecundity, it was thought that this unpredictable environment may shape the reproductive strategies of animals inhabiting it. -

The atlas and axis of all chamaeleonid genera (Brookesia, Rieppeleon, Archaius, Rhampho- leon, Nadzikambia, Bradypodion, Chamaeleo, Calumma, Furcifer, Kinyongia, and Trioceros) are studied here. Considerable morphological differences are revealed. Additionally, some taxa exhibit sexual dimor- phism in the atlas and axis. An extremely long, divided posterodorsal pro- cess is present in males of the Trioceros johnstoni 1 Trioceros jacksonii clade. The solid and well-developed morphology of the posterodorsal pro- cess in males of this taxon could reflect its competitive behavior—males fight with their horns and attempt to dislodge one another from branches during encounters. -

Even so, the medium and large mammal fauna remains poorly known and to date no systematic mammal surveys have been published from any of Mozambique’s mountains. We present results of a medium and large mammal survey of Serra Jeci’s Mt Chitagal, Mt Sanga and the Njesi Plateau in Niassa, northern Mozambique; the first mammal diversity data collected from these isolated mountains. We recorded 27 mammal species, of which six represent range expansions; Sykes’s monkey (Cercophitecus mitis), Mozambique dwarf galago (Paragalago granti), Smith’s red rock hare (Pronolagus rupestris), lesser cane rat (Thryonomys gregorianus), rock hyrax (Procavia capensis) and African buffalo (Syncerus caffer). We also reviewed and collated records of medium and large mammals from previously published fieldwork on northern Mozambique’s mountains, amounting to a total of 34 large mammal species from seven montane areas, highlighting the lack of mammalian knowledge in Mozambique’s Afromontane habitats. -

Box 13147, Humewood 6013, South Africa. 4Evolutionary Genomics Group, Department of Botany and Zoology, University of Stellenbosch, South Africa *Corresponding author Abstract The taxonomic history and composition of the genus Bradypodion as construed by Klaver & Böhme (1986) and new morphological and molecular data relevant to the taxonomy of the group is reviewed. The combined evidence strongly supports a formal rearrangement of the group into three distinct genera. Bradypodion, type species Chamaeleo pumilus Daudin 1802, is retained for the southern African species. Two new genera are erected to accommodate additional well-diagnosed clades within central and east African species previously referred to Bradypodion. Species of the “fischeri complex” are assigned to Kinyongia gen. nova, whilst the endemic Mulanje chameleon is placed in the monotypic genus Nadzikambia gen. nova. Key words: Chamaeleonidae, Bradypodion, Phylogeny, new genera, mitochondrial and nuclear DNA Introduction The first species of Bradypodion to be formally described was Chamaeleo pumilus Daudin 1802. Fitzinger (1843) subsequently designated pumilum as the type species for a new genus, Bradypodion. -

CoP13)] SPECIES SELECTED FOLLOWING COP15 1. This document has been prepared by the Secretariat. 2. At its 25th meeting (AC25, Geneva, 2011) and following the 15th meeting of the Conference of the Parties (CoP15, Doha, 2010), the Animals Committee selected 24 taxa for the Review of Significant Trade in compliance with paragraph a) and b) of Resolution Conf. 12.8 (Rev. CoP13) on Review of Significant Trade in specimens of Appendix-II species. (see documents AC25 Doc. 9.3 and AC25 Doc. 9.6). 3. At its 26th meeting (AC26, Geneva, 2012), the Committee reviewed the available information on these taxa in accordance with paragraph f) of Resolution Conf. 12.8 (Rev. CoP13). In instances where the Committee was satisfied that Article IV, paragraph 2 (a), 3 or 6 (a), was correctly implemented, it eliminated the species from the review with respect to the range State concerned, and these range States were notified accordingly by the Secretariat (see document AC26 Doc.12.3 and the summary record of AC26). 4. At AC26, the Committee also agreed that prior to the compilation of information called for in paragraph g), range States that had been kept in the process due to a lack of response but where no commercial trade had been recorded over the most recent 10 years, would be removed from the process in consultation with the Animals Committee.
