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. -
Comparative Ecology and Behaviour of Eastern Potto Perodicticus Ibeanus and Central Potto P
Journal of East African Natural History 107(1): 17–30 (2018) COMPARATIVE ECOLOGY AND BEHAVIOUR OF EASTERN POTTO PERODICTICUS IBEANUS AND CENTRAL POTTO P. EDWARDSI IN ANGOLA, CAMEROON, KENYA, NIGERIA, RWANDA AND UGANDA Averee M. Luhrs, Magdalena S. Svensson & K. Anne-Isola Nekaris Nocturnal Primate Research Group, Oxford Brookes University Headington, Oxford, OX3 0BP, UK [email protected]; [email protected]; [email protected] ABSTRACT Comparative behavioural research reveals both intra- and inter-species diversity among primates. Few long-term behavioural studies have been conducted on African nocturnal primates. Here we describe and compare behavioural and ecological observations on two species of pottos (Perodicticus ibeanus and P. edwardsi) across ten sites. We observed a total of 51 P. edwardsi and 28 P. ibeanus. We recorded all 21 postures within an established lorisid ethogram, as well as 42 of 50 behaviours. Eating, locomotion, freezing, resting and sniffing were the most common behaviours. We recorded behaviours not previously described for perodicticines, including bark chewing and unique vocalisations. Three species of pottos are now recognised, with potentially more species to be revealed within this cryptic and nocturnal genus. Although there are similarities among potto species, we show that unique ecological adaptations and behaviours may further elucidate their diversity. Keywords: Behaviour, nocturnal, Lorisidae, Perodicticinae, Perodicticus, taxonomy INTRODUCTION In primates, comparative ethological research has uncovered differences in behaviour and habitat use between and among similar species living in sympatry or within the same species living in different faunal communities (Charles-Dominique et al., 1980; Garber & Leigh, 1988; McGraw, 1988; Gebo & Chapman, 1995). -
Jonathan Kingdon Mammals of Africa
Jonathan Kingdon Mammals of Africa “Mammals of Africa” Drawings as Documents This exhibition consists of drawings, watercolours and prints drawn from the recently published “Mammals of Africa” (MOA), a six volume inventory of the entire continent’s mammalian fauna and including Homo sapiens! The documents illustrating MOA have drawn heavily on images previously published in three earlier works, “East African Mammals” (1971-1982) and my Field and Pocket Guides (1997 & 2004). MOA started with the stipulation that I was to be its sole illustrator and there would be no photographs. One reason for excluding them came from an experience in my 20’s, when medical colleagues, researching malnutrition and kwashiorkor in rural children, asked me to investigate the effectiveness of imagery among illiterate peasant farmers. What I found was that the latter were unable to interpret photographs, holding them, puzzled, upside down. Instead, they loved medieval iconography and understood drawings. Subsequently, I learned that the visual cortex in human brains does not operate like a camera but, like the process of drawing, puts lines and outlines around things, isolating the forms of visual interest from their surroundings. It is not only rural illiterates that are visually uneducated; one sophisticated western scientist, reviewing “East African Mammals,” wrote “This book is unusual in there being no pictures, just drawings”, using the common misnomer for photography as a “picture”, which originally meant a painted image by an artist. The habit of carefully examining an image to extract its meaning is now rare and most people scan images as rapidly as they would scan road signs or airport signage. -
Other Primate Species* A
J. Anat. (1984), 138, 2, pp. 217-225 217 With 3 figures Printed in Great Britain The structure of the vomeronasal organ and nasopalatine ducts in Aotus trivirgatus and some other primate species* A. J. HUNTER, D. FLEMING AND A. F. DIXSON Department of Reproduction, Institute of Zoology, Zoological Society of London, Regents Park, London NW1 (Accepted 16 June 1983) INTRODUCTION The vomeronasal organ was first fully described by Jacobson (1811), although its presence had been noted by Ruysch (1703). Since its discovery, the occurrence and structure of the organ has been well documented in many species (Allison, 1953; Negus, 1956; Cooper & Bhatnagar, 1976; Vaccarezza, Sepich & Tramezzani, 1981). The vomeronasal organ is a bilateral, symmetrical structure encapsulated by cartil- age. It lies at the base of the nasal septum and, in most mammals, opens anteriorly into the nasopalatine canal via the vomeronasal duct. Detailed studies of the structure of the vomeronasal organ have only been carried out in a few primate species: the mouse lemur, Microcebus murinus (Schilling, 1970); the tarsier, Tarsius bancanus borneanus (Starck, 1975); the bushbaby, Galago senega- lensis (Eloff, 1951), Galago demidovii and the squirrel monkey, Samiri sciureus (Maier, 1980). Frets (1912) studied the organ in thefetuses ofa number ofPlatyrrhine and Catarrhine species, but in only one adult specimen of Cebus hypoleucus. He concludes that the organ is well developed only in Platyrrhine primates. Similar results were obtained by Jordan (1972) and Loo (1974), with the organ being present in the slow loris, lemur and capuchin monkey but absent in the gibbon and various macaque species, although in many studies it is not clear whether fetal or adult material has been used (e.g. -

Pottos and Angwantibos Traded for Bushmeat
Pottos and Angwantibos Traded for Bushmeat Hofner Alexandra N. and Svensson Magdalena S. Svensson and Friant (2014) provided some of the first quantified evidence of the trade in nocturnal lorisids in Africa, including an overview of pottos (Perodicticus spp.) and angwantibos (Arctocebus spp.) in the bushmeat trade (Figure B29.2.1). Relatively little is known about the relationships between wildlife economies and these nocturnal primates (Svensson et al., 2016). Studies on the vulnerability of non- human primates to hunting pressure in Afrotropical forests are primarily specific to the effects of shotgun hunting on diurnal primate communities. These studies mostly focus on large conspicuous species known to be common targets of African hunters, for example guenons (Cercopithecus spp.; Covey and McGraw, 2014; Cronin et al., 2016; Linder and Oates, 2011; Remis and Robinson, 2012), colobus monkeys (Colobus satanas; Kümpel et al., 2008 and Procolobus pennantii; Cronin et al., 2016) and mangabeys (Lophocebus albigena; Remis and Robinson, 2012). Despite the lack of research situating smaller, more inconspicuous lorisids as a focus in bushmeat studies, pottos and angwantibos are noted as trade items by researchers and have been reported in larger studies across their range (Table 1). Figure 1. Smoked potto carcass in Nigeria (photograph by S. Friant) and angwantibo hunted in the Republic of Congo (photograph by J. Dewilde). Given their relatively small body mass and, subsequently, inappreciable economic value, lorisid species are often consumed within villages; trade tends to be confined to rural markets and/or roadsides (Hofner et al., 2018; Svensson and Friant, 2014). Consequently, reports of these species in large-scale surveys targeting urban markets, a common cost-effective tool used to quantify the bushmeat trade (Fa et al., 2006; Kümpel et al., 2008; Taylor et al., 2015), may represent an underestimation of total regional lorisid offtake levels. -
