Greater Bamboo Lemur Madagascar
Madagascar Greater Bamboo Lemur Prolemur simus (Gray, 1871) Madagascar (2002, 2004, 2006, 2008) Patricia C. Wright, Eileen Larney, Edward E. Louis Jr., Rainer Dolch & Radoniana R. Rafaliarison The greater bamboo lemur (Prolemur simus) is the largest of Madagascar’s bamboo-eating lemurs (Albrecht et al. 1990) and the most critically endangered lemur in Madagascar (Ganzhorn et al. 1996, 1997; Konstant et al. 2006; Mittermeier et al. 2006; Ganzhorn and Johnson 2007; Wright et al. 2008). Although its placement in Prolemur has been questioned (for example, Tattersall 2007), it now represents a monospecific genus, based on a suite of distinctive dental and chromosomal characteristics (Vuillaume-Randriamanantena et al. 1985; Macedonia and Stanger 1994) that support its separation from the genus Hapalemur (cf. Groves 2001). Genetic studies further suggest that Hapalemur may, in fact, be more months, while it relies on its shoots and leaves at other closely related to the genus Lemur (Rumpler et al. times of the year. Prolemur simus supplements its diet 1989; Macedonia and Stanger 1994; Stanger-Hall 1997; with fruits, flowers, soil and fungi (Meier and Rumpler Fausser et al., 2002).

Sexual Dimorphism in Crowned Lemur Scent-Marking
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 31 May 2021 doi:10.20944/preprints202105.0761.v1 Article Sexual dimorphism in crowned lemur scent-marking. Emily Elwell 1, David Walker 1 and Stefano Vaglio 1,2* 1 Department of Biology, Chemistry and Forensic Science, University of Wolverhampton, Wolverhampton WV1 1LY, United Kingdom 2 Department of Anthropology & Behaviour, Ecology and Evolution Research (BEER) Centre, Durham University, Durham DH1 3LE, United Kingdom * Correspondence: [email protected]; Tel.: +44-0190-232-3328 Simple Summary: Primates are typically thought to use hearing and vision more than the sense of smell. However, lemurs show a complex olfactory repertoire which includes conspicuous scent-marking behaviours. We studied two family groups of crowned lemurs at Colchester and Twycross zoos (UK) by combining behavioural observations and chemical analyses of odour secretions released via scent-marking. Male lemurs scent-marked most frequently, showing three types of behaviours: ano-genital marking for applying their scent on to females; head marking for placing their secretions on or near the mark left by another individual; and wrist marking to deposit their mark in specific meaningful areas of the enclosure. Female lemurs displayed only ano-genital marking primarily on feeding devices. We detected a total of 38 volatile compounds in male ano-genital scent-marks and 26 in female ano-genital odour secretions, including many compounds that have been identified in odour profiles of other primates. In conclusion, we found sexual dimorphism in crowned lemurs. In males head and wrist marking behaviours would play defensive territorial functions, while ano-genital marking may be related to socio-sexual communication; female ano-genital marking could be involved in resource defense. -

ABSTRACT GENUS VARECIA: ANATOMY, MORPHOLOGY, and PATHOLOGY Elise R. Orellana, MS Department of Biological Sciences Northern Illi
ABSTRACT GENUS VARECIA: ANATOMY, MORPHOLOGY, AND PATHOLOGY Elise R. Orellana, MS Department of Biological Sciences Northern Illinois University, 2015 Virginia L. Naples, Director An anatomical normal was established for the forelimb and hindlimb of the Genus Varecia through observation of skeletal remains and a detailed dissection of the musculature of a black and white ruffed lemur, Varecia variegata. This was used as a healthy state for comparison with a red ruffed lemur, Varecia rubra, displaying a periosteal disease affecting the long bones. This disease presented as large lesions growing along the diaphyses and epiphyses of the ulna, radius, tibia and fibula as well as on the carpals, metacarpals, tarsals, metatarsals, and phalanges. Dissection showed that these lesions avoided the points of origin and insertion of the limb musculature. Instead, the calcified lesions grew over the tendons and some muscle in the wrist and ankles reducing dexterity and range of motion in climbing and walking activities. This study determined the initial diagnosis of primary hypertrophic osteoarthropathy to be a misdiagnosis based on the absence of the three main symptoms of the disease: finger clubbing, pachydermia, and periostitis. Instead the location, size, and progression of the bony lesions make Nora’s lesions (bizarre parosteal osteochondromatous proliferation) are more appropriate diagnosis. The skeletomuscular data provided in this work allow for Varecia to be used as a model for morphological studies, in disease recognition and diagnosis, and answered questions regarding the effects of the periosteal disease described.

Some lemur species are prone to extreme weight gain in captivity, yet for others a healthy body condition is typical. The first aim of our study was to examine possible ecological explanations for these species’ differences in susceptibility to captive weight gain across 13 lemur species. Our second aim was to explore demographic and environmental risk factors across individuals from the four best-sampled species. We found a potential ecological explanation for susceptibility to captive weight gain: being adapted to unpredictable wild food resources. Additionally, we also revealed one environmental and four demographic risk factors, e.g., increasing age and, for males, being housed with only fixed climbing structures. Our results indicate targeted practical ways to help address weight issues in affected animals, e.g., by highlighting at-risk species for whom extra care should be taken when designing diets; and by providing a mixture of flexible and fixed climbing structures within enclosures. -
Hair Morphology of Gray Slender Loris (Loris Lydekkerianus) and Bengal
Journal of Entomology and Zoology Studies 2017; 5(3): 386-388 E-ISSN: 2320-7078 P-ISSN: 2349-6800 Hair morphology of Gray Slender Loris (Loris JEZS 2017; 5(3): 386-388 © 2017 JEZS lydekkerianus) and Bengal Slow Loris (Nycticebus Received: 28-03-2017 Accepted: 29-04-2017 bengalensis) Manokaran Kamalakannan Zoological Survey of India, M-Block, New Alipore, Kolkata, Manokaran Kamalakannan West Bengal, India Abstract The present study was undertaken to know the hair morphology of two Indian lorises Gray Slender Loris Loris lydekkerianus and Bengal Slow Loris Nycticebus bengalensis. The laboratory study was conducted at the Mammal & Osteology section, Zoological Survey of India, Kolkata during January – July 2016. Microscopic hair analysis of two lorises was done using an optical light microscope for its species identification. The hair of two lorises can easily be identified on basis of their ‘unicellular regular’ and ‘ladder’ structure of medulla and ‘oval or circular’ shape of the cross-section of hair. The high-resolution photo-micrographs and key characteristics of hair presented here can be used as an appropriate reference for species identification. Keywords: Lorises, hair morphology, dorsal guard hair, unicellular regular, ladder 1. Introduction The identification of mammal species through hair morphology is one of the methods adapted for identification of confiscated materials received from the different wildlife enforcement agencies and the analysis of mammal hairs has long been useful in the study of prey-predator food habits using the scat-hair analysis [3, 9, 10]. Adequate and systematic knowledge of the structure of dorsal guard hair is necessary to identify the species and data generated from microscopic characteristics of dorsal guard hair will provide for a preparation of identification keys for respective species [4]. -
Subspecific Divergence in the Black Lemur's Low-Pitched Vocalizations
The Open Acoustics Journal, 2008, 1, 49-53 49 Open Access Subspecific Divergence in the Black Lemur’s Low-Pitched Vocalizations M. Gamba* and C. Giacoma Department of Animal and Human Biology, University of Torino, Italy Abstract: Previous studies offered very preliminary information on the vocal repertoire of Eulemur macaco macaco and Eulemur macaco flavifrons. They agreed on the fact that both subspecies emit low-pitched vocalizations, called grunts, of different duration. Through all-occurrence and focal animal observations, we recorded the vocal activity of 31 black le- murs (12 E. m. macaco and 19 E. m. flavifrons) housed in 7 institutions, both in Europe and in Madagascar. We measured both temporal and spectral properties to describe long grunts quantitatively. We extracted acoustic parameters in the per- spective of the source-filter theory of sound production. From spectrograms, we measured call duration and 6 larynx- related features and, using Linear Predictive Coding spectra, we measured four vocal tract related acoustic properties. Our quantitative analysis has statistical support for the classification of long grunts. Using individual mean values and multi- variate Discriminant Function Analysis we have been able to successfully classify 96.8 % of the vocal signals to the sub- species of the emitter. Acoustic cues of both larynx-related and vocal tract-related acoustic parameters offered support for sub-specific recognition potential. However, univariate analyses showed that formants should be providing listeners with subspecies-specific information.
