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. -

Cathemeral Activity Patterns of the Blue-Eyed Black Lemur Eulemur Macaco Flavifrons in Intact and Degraded Forest Fragments

Four groups of E. m. flavifrons in 2 forest frag- ments with different degrees of degradation were followed for 24 h mo–1 over a 7 mo period between July 2004 and July 2005. Blue-eyed black lemurs exhibited a bimodal activity pattern which peaked during the morning and evening twilight. The groups consistently showed activity bouts both during the day and at night, a behaviour that corresponds to Tattersall’s (1987) definition of cathemerality. The proportion of illuminated lunar disc and the nocturnal illumination index were positively associ- ated with the amount of nocturnal activity. Total activity, both diurnal and nocturnal, was signifi- cantly higher in the secondary than in the primary forest. In view of our results, the cathemeral behaviour of E. m. flavifrons may best be explained as flexible responses to a framework of varying environmental factors, each of which may enhance or inhibit activity within the lemurs’ range of adaptability. -
Rare Mammals of Madagascar
Rare Mammals of Madagascar Trip Highlights from November 2019 and May 2016 by Ian Loyd Introduction Madagascar must be one of the most extraordinary destinations in the world for those interested in natural history. This record of some stand out sightings and where to find key species will hopefully help those planning a trip. Often referred to as the “Eighth Continent” and “The Big Red Island”, Madagascar is the world’s oldest and fourth largest island and after millions of years of isolation, a wildlife holiday there is truly unlike anywhere else. There is a vast range of ecosystems to explore: wet rainforest, dry tropical deciduous forest and the unique spiny forest found only in Madagascar’s far southwest. In addition, there are also coral reefs and stunning white sand beaches to enjoy along the coast, plus the unique stone forests known as tsingy and fascinating cultures to discover. Nearly all of Madagascar’ staggering biodiversity is found nowhere else and much of it is sadly increasingly threatened with extinction. Wildlife highlights undoubtably include the mysterious nocturnal aye aye, iconic ring-tailed lemur, the beautiful sifaka family, the agile indri, tiny mouse lemurs, charismatic fossa, both giant and miniature chameleons, camouflaged leaf-tailed geckos, colourful frogs and its fantastically varied endemic birds. (2)…/ Wildlife tourism has emerged as a major source of foreign income for Madagascar. By visiting you contribute directly to the conservation of its precious remaining forests with their unique wildlife, and the welfare of its people who are among the poorest (yet friendliest) in the world. Your presence facilitates the hiring of park rangers who guard the precious reserves from illegal logging, slash-and-burn farmers and bush-meat hunters. -
From Darkness to Daylight: Cathemeral Activity in Primates
JASs Invited Reviews Journal of Anthropological Sciences Vol. 84 (2006), pp. 1-117-32 From darkness to daylight: cathemeral activity in primates Giuseppe Donati & Silvana M. Borgognini-Tarli Dipartimento di Biologia, Unità di Antropologia, Università di Pisa, Via S. Maria, 55, Pisa, Italy, e-mail: [email protected] Summary – Within the primate order, Haplorrhini and Strepsirrhini are adapted to diurnal or nocturnal lifestyle. However, Malagasy lemurs exhibit a wide range of activity patterns, from almost completely nocturnal to almost completely diurnal, while others are active over the 24-hours. Cathemerality, the term minted by Tattersall (1987) to define the latter activity style, has been recorded in Eulemur and Hapalemur, as well as in some populations of the New World monkey Aotus. As most animals specialize in a particular phase of the 24- hour cycle, the cathemeral strategy is expected to be the consequence of powerful pressures. We will review hypotheses and findings on ultimate reasons of primate cathemeral activity, present proximate factors shaping the activity cycle and discuss the possible roles of feeding competition, food shortage and dietary quality, thermoregulation, and predation in making this activity advantageous. Overall, we will see how unstable environments and various community characteristics would tend to select for a flexible activity phase. Most attempts to explain cathemerality have relied on adaptive explanations, which assume that this activity is stable and deep-rooted. In contrast, some researchers have suggested that cathemerality represents a non-adaptive transitional state between nocturnality and diurnality. Chronobiology studies indicate that cathemeral species should be considered as dark active primates, thus favouring a recent origin. -
(Eulemur Mongoz) at the Lemur Conservation Foundation, Myakka City, Florida
1 Exploring the Impacts of Temperature on the Activity Patterns of Mongoose Lemurs (Eulemur mongoz) at the Lemur Conservation Foundation, Myakka City, Florida _________________________ An Honors Thesis Presented to The Independently Designed Major Program The Colorado College _________________________ by Rebecca Twinney May 2017 Approved: ____________________________Krista Fish Date: ________________________________ 04/19/2017 2 Abstract This study focused on the activity patterns of a male-female pair of semi-free ranging mongoose lemurs (Eulemur mongoz) in Myakka City, Florida. Despite hypotheses that a change in temperature drives the seasonal shift in the species’ activity patterns, previous research has been unable to conclusively isolate this variable. Because the semi-free ranging environment at the Lemur Conservation Foundation provided a constant food source and limited predation, it enabled this study to isolate the effect of temperature. The data illustrated no significant difference between hourly activity levels during sampling periods in the summer and fall of 2016 (P = 0.32). Despite lower temperatures in the fall (P = 0.01), the lemurs’ activity patterns did not significantly alter from those in the warmer summer months. These findings indicate that seasonal food availability, rather than temperature, drives the shifting activity patterns of wild mongoose lemurs. While Curtis et al. (1999) originally suggest that the lemurs’ higher fiber intake during the dry season drives this change in activity, more research is needed in order to fully understand this relationship. INTRODUCTION Thermoregulation In subtropical environments with temperatures that fluctuate with the season, most endothermic animals must rely on behavioral mechanisms of thermoregulation (Donati et al., 2011). In order to maintain homeostasis, species may conduct thermogenesis, the production of body heat, or thermolysis, the dissipation of body heat (Terrien et al., 2011).
