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.

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.

Jenkins3,4 & Olga R. Ravoahangimalala1 1Département de Biologie Animale, Université d’Antananarivo, Madagascar 2Durrell Institute of Conservation and Ecology, University of Kent, Canterbury, UK 3School of Biological Sciences, University of Aberdeen, UK 4Madagasikara Voakajy, Antananarivo, Madagascar We studied the density and abundance of chameleons in a lowland Malagasy rainforest during the austral summer and winter. Nocturnal searches for chameleons were conducted along transects within relatively intact forest and vegetation on abandoned agricultural land adjacent to the forest. Four chameleon species were encountered during the study, Brookesia superciliaris, Calumma parsonii parsonii, Calumma nasutum and Furcifer pardalis. Brookesia superciliaris was most common inside relatively intact forest and the few individuals located in the regenerating forest on abandoned agricultural land were found in tiny, isolated patches of degraded rainforest next to rivers. Calumma p. parsonii was only encountered on three occasions in relatively intact forest and was a rare member of the community. The abundance of C. nasutum was highest in relatively intact forest but this species also occurred in vegetation on abandoned agricultural land. Furcifer pardalis was only found on the abandoned agricultural land, where it was observed laying eggs in sandy soil in August. The abundance of all species in habitats alongside rivers was higher in January than July–August, with the exception of C. p. parsonii, which was not detected during the former period. Additional investigations into habitat preference of chameleons and surveys in other forests in region are needed to establish whether the low abundance of C.

CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ----------- o ---------- Douzième réunion de la Conférence des Parties Santiago (Chili), du 3 au 5 novembre 2002 --------------- o -------------- Proposition d’amendement des annexes suivant la Résolution de CITES Conf. 9. 24 A. Proposition Classement de l’espèce Brookesia spp (GRAY 1865) en Annexe II de la CITES. Compte tenu des synonymies entre certaines espèces (Raxworthy & Nussbaum, 1995) et des validités des noms d’espèces par Raxworthy (in litt.), 25 espèces de Brookesia sont reconnues pour cette proposition. Beaucoup d’espèces de Brookesia sont nettement affectées par le commerce international pendant les deux dernières années. Les données d’exportations de ces espèces au cours des deux dernières années le confirment (MEF, 2000, 2001) . A part B. perarmata, qui est déjà proposé en Annexe I, les 25 espèces sont considérées comme menacées d’extinction suivant l’Article II, paragraphe 1 remplissant les critères biologiques B (i) dans l’Annexe II de la Résolution de CITES Conf. 9. 24. Les autres espèces de ce genre devraient être inscrites en Annexe II conformément à l’Article II, paragraphe 2b) remplissant le critère B. Ainsi, elles sont considérées comme étant l’objet d’un amendement des Annexes de la CITES. B. Auteur de la proposition Madagascar C. Justificatif Brookesia ou caméléons nains sont classés parmi les faux caméléons, endémiques de Madagascar (Glaw & Vences, 1994 ; in Carpenter, 2002).

Brookesia Micra Fact Sheet
Brookesia Micra Fact Sheet Common Name: Brookesia micra / Leaf Chameleon / Stumped-tailed Chameleon Scientific Name: Brookesia micra Wild Status: Near threatened Habitat: In Leaf Litter Country: Madagascar, on a small island called Nosy Hara Shelter: Climb up into tree branches as high as 3.9 inches at night to sleep Life Span: In captivity up to 10 years, In wild unknown Size: About an inch from nose to tail Details: The Brookesia micra is a relatively new discovered species. They live in Madagascar on an Island called Nosy Hara. They are the tiniest of chameleons discovered so far and only grow to about an inch long from nose to tail. They tend to be active during the day and spend time in leaf litters ,while at night they make the high 4 inch climb to the top of tree branches to sleep. They have the ability to use their tail as an extra leg, similar to a peg leg. They are mostly grey, brown in color with a few spots of orange near their tail. If they are stressed out, they are able to change color. Their main diet is small fruit flies and white flies. As of now, little is known of their breeding habits. Cool Facts: • Brookesia micra is the tiniest chameleon in the world as of now. • A baby Brookesia micra is so tiny it can stand on the tip of a person's finger nail. • The Brookesia micra tails have 20 vertebrae compared to the usual 50 of larger chameleons. • Brookesia micra can use their tail as a leg to help them climb, which other chameleons cannot do.
