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. -

Campo Alegre s/n, 4169-007 Porto, Portugal 5Corresponding author Abstract We describe a new Brookesia species from a forest fragment located 13 km south of Ambalavao in the southern part of Madagascar's central high plateau. Brookesia brunoi sp. nov. is one of the few arid-adapted Brookesia species inhabiting deciduous forests on the western slope of the central high plateau of the island (around 950 m a.s.l.). So far the species has only been observed in the private Anja Reserve. The species belongs to the Brookesia decaryi group formed by arid-adapt- ed Brookesia species of western Madagascar: B. bonsi Ramanantsoa, B. perarmata (Angel), B. brygooi Raxworthy & Nussbaum and B. decaryi Angel. Brookesia brunoi differs from the other four species of the group by a genetic divergence of more than 17.6% in the mitochondrial ND2 gene, and by a combination of morphological characters: (1) nine pairs of laterovertebral pointed tubercles, (2) absence of enlarged pointed tubercles around the vent, (3) presence of poorly defined laterovertebral tubercles along the entire tail, (4) by the configuration of its cephalic crest, and (5) hemipenial morphology. -

CoP13)] SELECTION OF SPECIES FOR TRADE REVIEWS FOLLOWING COP16 1. This document has been prepared by the Secretariat. 2. In Resolution Conf. 12.8 (Rev. CoP13) on Review of Significant Trade in specimens of Appendix-II species, the Conference of the Parties: DIRECTS the Animals and Plants Committees, in cooperation with the Secretariat and experts, and in consultation with range States, to review the biological, trade and other relevant information on Appendix-II species subject to significant levels of trade, to identify problems and solutions concerning the implementation of Article IV, paragraphs 2 (a), 3 and 6 (a)... 3. In accordance with paragraph a) of that Resolution under the section Regarding conduct of the Review of Significant Trade, the Secretariat requested UNEP-WCMC to produce a summary from the CITES Trade Database of annual report statistics showing the recorded net level of exports for Appendix-II species over the five most recent years. Its report is attached as Annex 1 (English only) to the present document. The raw data used to prepare this summary are available in document AC27 Inf. 2. 4. Paragraph b) of the same section directs the Animals Committee, on the basis of recorded trade levels and information available to it, the Secretariat, Parties or other relevant experts, to select species of priority concern for review (whether or not such species have been the subject of a previous review). -

AC29 Doc. 13.3 Annex 2 Selection of species for inclusion in the Review of Significant Trade following CoP17 To comply with Stage 1 a) of Resolution Conf. 12.8 (Rev. CoP17) and the Guidance regarding the selection of species/country combinations outlined in Annex 2 of the Resolution, the UN Environment World Conservation Monitoring Centre (UNEP-WCMC) has produced an extended analysis to assist the Animals Committee with their work in selecting species for inclusion in the Review of Significant Trade following CoP17. A summary output, providing trade in wild, ranched, source unknown and trade without a source specified over the five most recent years (2011-2015), to accompany this analysis is provided in AC29 Doc. 13.3, Annex 1. The methodology for the extended analysis was discussed by the 2nd meeting of the Advisory Working Group (AWG) of the Evaluation of the Review of Significant Trade (Shepherdstown, 2015). The AWG concluded that three criteria should be retained within the methodology (“high volume trade/high volume trade for globally threatened species”, “sharp increase in trade” and “endangered species in trade”), but that two previously used criteria added little value to the prioritisation exercise (“high variability in trade” and “overall increase/overall decrease in trade”). In addition, it was agreed to refine the methodology for “High Volume” trade to ensure that thresholds are set at a fine taxonomic resolution (order level) to ensure representation for all taxonomic orders. It was also agreed to include analysis of “Sharp Increase” in trade at the country level, as well as at the global level. -

Roost Site Characteristics of Sympatric Dwarf Chameleons (Genus Brookesia) from Western Madagascar
Roost site characteristics of sympatric dwarf chameleons (genus Brookesia) from western Madagascar Joseph Christian Randrianantoandro1, Roma Randrianavelona1,2, Raphali Rodlis Andriantsimanarilafy,3 Hantalalaina Elisoa Fideline2, Daniel Rakotondravony2, Richard K.B. Jenkins1,4,∗ Abstract. Madagascar’s Brookesia dwarf chameleons are believed to require relatively intact forest for survival. Although they have featured in herpetological surveys, taxonomic reviews and trade assessments, very little is known about their microhabitat requirements or ecology. Over a 5 night period in a deciduous forest in western Madagascar we recorded the night roosting sites for three sympatric Brookesia species. We calculated the area and distance between successive night roost locations and described the characteristics of each roost. Distance between roosts and the area used were larger for B. brygooi and B. perarmata than B. exarmata. The distance between roosts was significantly greater for male than female B. brygooi and B. perarmata. Roost sites were generally in low vegetation (<0.75 m) with the animals located on stems or leaves. Roost height differed significantly between the species, with B. brygooi using the highest perches and B. exarmata the lowest. Keywords: Brookesia, chameleon, Madagascar, roost. Chameleons lend themselves well to field study at night. There are few available data on how because they can be readily located at night co-occurring dwarf chameleons use the forest whilst roosting and have distinct habitat prefer- habitat or whether there are gender-based dif- ences which often include intact forests. Some ferences in their ecology. Despite major mor- studies in Madagascar have reported differences phological and behavioral differences between in chameleon abundance or density between Brookesia and other Malagasy chameleons, different forest habitats (e.g.
