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. -
Panther Chameleon Furcifer Pardalis Adult Size: Males up to 20 Inches
Care and information sheet Panther Chameleon Furcifer pardalis Adult Size: Males up to 20 inches. Females much smaller, almost half the size of males. Life Span: Up to ten years in captivity, with an average lifespan of five. Breeding females tend only to live a couple of years. Male/Female Differences: Males are almost twice the size of females and are much more brightly coloured Compatibility: Panther Chameleons are solitary creatures and should be kept as such. Females may be introduced to a male's cage during breeding season, but should be removed as soon as possible. Origin: Panther Chameleons are exclusively found on the island of Madagascar Climate: Warm temperate, high humidity but not excessively hot. Day Cycle: Diurnal (awake during the day) Temperature: A gradient of heat from 75 – 85°F should be provided during the day with a basking point. Temp should drop 10 – 15° at night, but not below 65. Lighting: Chameleons need a source of UVB light to properly metabolize calcium. This should be provided in the form of a reptile fluorescent or mercury vapor bulb in a normal day cycle (10 – 12 hours/day). Humidity: High humidity is essential to a Panther's well being. 65-80%. Accomplish this by misting the cage several times daily or with the addition of moisture retaining decorations, such as live plants or water features.

Panther Chameleon
Panther Chameleon Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Family: Chamaeleonidae Genus: Furcifer Size: Male length: Up to 23cm Female length: Up to 13.5cm Exhibiting some of the most spectacular colour variations of all chameleons, the large-bodied panther General chameleon (Furcifer pardalis) is highly sought after by reptile keepers. Interestingly, populations from different locations within this species’ range each have a particular colouration and patterning, which is generally most pronounced during courtship or defensive displays. Male panther chameleons from the Madagascan island of Nosy Be, for example, have uniform striking blue-green, emerald-green or turquoise bodies, whereas males from the north-west coast are vivid pink, with a yellowish white stripe along the flanks, a colour form known as “the pink panther.” Other colours found in the males may include orange, red and dark green, with a hugely variable patterning of coloured bands, stripes and spots, especially around the head and eyes. By contrast, female panther chameleons are mostly dull, uniform grey, brown or faint green, except during breeding, when receptive females become pale or vivid orange to pink, later changing to black, with bright orange or pink vertical bars when gravid. Like many other chameleon species, the panther chameleon’s head extends at the rear into a raised bony prominence known as a “casque” Endemic to Madagascar, the panther chameleon is found in coastal regions and islands of central- Range eastern, north-eastern, northern and north-western Madagascar. Introduced populations are also found on the islands of Reunion and Mauritius, around 500 kilometres east of Madagascar The panther chameleon mainly inhabits lowland, humid forest. -

National Parks in Madagascar
NATIONAL PARKS IN MADAGASCAR Madagascar’s National Parks are divided into 4 parts: Deciduous Forest, Eastern Rain Forests, Island and Coastal and Spiny Forests and in total have about 28 National Parks across the island worth visiting DECIDUOUS FOREST 1. Zombitse-Vohibasia National Park Normally included as a short stop between Isalo and Tulear, the forest of Zombitse- Vohibasia is in a transition zone between dry deciduous and spiny forest habitats. Birders will appreciate seeing Appert’s greenbul, found nowhere else, giant, Coquerel’s and olive-capped couas, as well as various vanga species. 2. Andringitra National Park A spectacular and biodiverse reserve with an altitude range of 500 to 2,658 metres and mountainous outcrops of ancient Precambrian granite, waterfalls, lakes and unusual vegetation. Pic Boby, Madagascar’s second highest mountain, is a tough climb, but there are other less challenging trails through some magnificent scenery and habitats, including lowland forest, high humid tropical forest, sclerophyll and bamboo forest, bush and heathland. It has much endemic flora and over 100 species of birds, as well as over 50 mammal species including mountain-adapted ring tailed lemurs with thick coats. The climate ranges from humid tropical in the lowland rainforests to below freezing at altitude – indeed, it is the only place in Madagascar where snow has been recorded. 3. Ankarafantsika National Park ( Ampijoroa) This prime example of tropical dry deciduous forest, combined with a lake harbouring Nile crocodiles and endangered Madagascar fish eagles, contains many other rare, endemic birds including Van Dam’s vanga, sickle-billed vanga and red-capped coua. -
Furcifer Pardalis (Panther Chameleon) – a Brief Species Descrip- Tion and Details on Captive Husbandry
BEMS Reports. 2016; 2(2): 27-38. A Multifaceted Peer Reviewed Journal in the field of Biology, Medicine, Engineering and Science Brief Review www.bemsreports.org | www.phcog.net Furcifer pardalis (Panther Chameleon) – A Brief Species Descrip- tion and Details on Captive Husbandry Ross McGeough ABSTRACT Chameleons of all species, have proven extremely delicate animals to work with in captivity. Many health concerns arise when they are maintained in improper conditions, from infections to inadequate nutrition, all of which will lead to the deterioration of the animals wellbeing and ultimately, a shortened lifespan. Therefore, understanding the most important problems which commonly occur in captive chameleons and the factors responsible for said problems, is paramount to the successful breeding and maintenance of chameleons in captivity. Furcifer pardalis or Panther Chameleons are one of the most common chameleons found in the pet trade, due in part to their impressive size, stunning variation in colouration, specialised morphological traits, unique personalities and most importantly, their relative hardiness when maintained in captivity. All of the aforementioned traits make Panther chameleons an exciting species to work with and an enjoyable challenge to successfully maintain, for the interested herpetologist. The aim of this paper, is to comprehensively review the history, anatomy and health issues associated with Panther chameleons and the current husbandry techniques used in maintain- ing said animals in captivity. The methods described in this paper are up to date guidelines for the successful husbandry of captive Panther chameleons and are as a result of many years of experience in keeping and breeding both Panther chameleons and various other chameleon species, whilst also drawing from expert literature in the field of captive chameleon husband- ry. -
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 -
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. -
Habitat Use and Abundance of a Low-Altitude Chameleon Assemblage in Eastern Madagascar
HERPETOLOGICAL JOURNAL 17: 247–254, 2007 Habitat use and abundance of a low-altitude chameleon assemblage in eastern Madagascar Jeanneney Rabearivony1, Lee D. Brady2, Richard K.B. 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.
