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]. -
Hibernation in Pygmy Lorises (Nycticebus Pygmaeus) – What Does It Mean?

This finding has considerable implications for our perception of torpor in this mammal group and demonstrates that torpor is probably more widespread in mammals than commonly thought. This article summarizes the current knowledge on the use of torpor in the pygmy loris and places it into the context of ongoing research on this topic.

Vietnamese Journal of Primatology (2009) 3, 37-44 Diet and feeding behaviour of pygmy lorises (Nycticebus pygmaeus) in Vietnam Ulrike Streicher Wildlife Veterinarinan, Danang, Vietnam. <[email protected]> Key words: Diet, feeding behaviour, pygmy loris Summary Little is known about the diet and feeding behaviour of the pygmy loris. Within the Lorisidae there are faunivorous and frugivorous species represented and this study aimed to characterize where the pygmy loris (Nycticebus pygmaeus) ranges on this scale. Feeding behaviour was observed in adult animals which had been confiscated from the illegal wildlife trade and housed at the Endangered Primate Rescue Center at Cuc Phuong National Park for some time before they were radio collared and released into Cuc Phuong National Park. The lorises were located in daytime by methods of radio tracking and in the evenings they were directly observed with the help of red-light torches. The observed lorises exploited a large variety of different food sources, consuming insects as well as gum and other plant exudates, thus appearing to be truly omnivorous. Seasonal variations in food preferences were observed. Omnivory can be an adaptive strategy, helping to overcome difficulties in times of food shortage. The pygmy loris’ feeding behaviour enables it to rely on other food sources like gum in times when other feeding resource become rare. Gum as an alternative food sources has the advantage of being readily available all year round. However it does not permit the same energetic benefits and consequently the same lifestyle as other food sources. But it is an important part of the pygmy loris’ multifaceted strategy to survive times of hostile environmental conditions. -
Loris Husbandry Manual REPRODUCTION Determining
Loris Husbandry Manual REPRODUCTION Determining Gender Slender Loris The penis and clitoris of lorises are similar in size, shape, and color, which complicates gender determination. The slender lorises can be even harder to sex because their testes are sometimes partially or completely inguinal. The size and location of their testes vary. The vagina is often covered with fur in young females, and close examination is often necessary for safe determination. The tip of the slender loris’ clitoris shows a gray patch (Meier et al., in preparation). The clitoris is smooth with the exception of hairs on the tip, as shown in Figure 13. The penis is covered with fine, velvet-like hairs that are barely visible. Figure 13: Discrimination of sex in lorises 28 Reproduction Slow and Pygmy Loris The penis of the slow and pygmy loris is shorter and thicker than the slender’s penis. The baculum is more developed and the callous pad at the tip of the baculum is larger. The scrotum differs from the slender loris’ scrotum by a distinct median ridge. The clitoris of the slow and pygmy loris is similar to the slender loris’ clitoris but it is relatively shorter and much thicker. The urethra opens at the clitoris tip. The vaginal opening is V-shaped and is situated at the root of the clitoris. Sex determination can often be accomplished shortly after birth in slow and pygmy lorises. The clitoris has a vertical slit at the tip, whereas the penis tip is more blunt and the slit is absent. In adults, the male genitalia show seasonal changes, and testes increase in size during late summer. -

Anne-Isola Nekaris1, Jarot Arisona Aji Pambudi2, Dwi Susanto2, Ridwan Djaffar Ahmad1,2, Vincent Nijman1,* 1Noctural Primate Research Group, Oxford Brookes University, OX3 0BP Oxford, UK 2Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Indonesia, Depok 16424, Indonesia ABSTRACT: Nocturnal mammals can be challenging to survey and, especially for many species that live in dense forest habitats, limited information is available on densities and distributions. We surveyed the endemic Javan slow loris Nycticebus javanicus in the montane forests of Mount Gede Pangrango, West Java, Indonesia. Surveys were conducted on 23 transects (260 h covering some 93 km) walking at variable speeds between 200 and 800 m h−1. Densities on individual tran- sects varied from 0 to 52 ind. km−2, with an overall density of 15.6 ind. km−2 (95% CI 9.7 to 25.2 ind. km−2). Encounter rates per kilometre were strongly influenced by the speed at which transects were walked, with fewer lorises detected at higher speeds. This effect was absent when consider- ing encounter rates per hour. Detectability and behavior of Javan slow lorises were not affected by the amount of lunar light and, in contrast to studies of some of their congeners, we found no evi- dence of lunar phobia or lunar philia. -
Foraging Behaviour of the Slender Loris (Loris Lydekkerianus Lydekkerianus): Implications for Theories of Primate Origins
Journal of Human Evolution 49 (2005) 289e300 Foraging behaviour of the slender loris (Loris lydekkerianus lydekkerianus): implications for theories of primate origins K.A.I. Nekaris* Department of Anthropology, Washington University, Campus Box 1114, One Brookings Drive, St. Louis, MO 63110, USA Received 3 May 2004; accepted 18 April 2005 Abstract Members of the Order Primates are characterised by a wide overlap of visual fields or optic convergence. It has been proposed that exploitation of either insects or angiosperm products in the terminal branches of trees, and the corresponding complex, three-dimensional environment associated with these foraging strategies, account for visual convergence. Although slender lorises (Loris sp.) are the most visually convergent of all the primates, very little is known about their feeding ecology. This study, carried out over 10 ½ months in South India, examines the feeding behaviour of L. lydekkerianus lydekkerianus in relation to hypotheses regarding visual predation of insects. Of 1238 feeding observations, 96% were of animal prey. Lorises showed an equal and overwhelming preference for terminal and middle branch feeding, using the undergrowth and trunk rarely. The type of prey caught on terminal branches (Lepidoptera, Odonata, Homoptera) differed significantly from those caught on middle branches (Hymenoptera, Coleoptera). A two-handed catch accompanied by bipedal postures was used almost exclusively on terminal branches where mobile prey was caught, whereas the more common capture technique of one-handed grab was used more often on sturdy middle branches to obtain slow moving prey. Although prey was detected with senses other than vision, vision was the key sense used upon the final strike.
