Gastrointestinal Parasites of Captive and Free-Living Lemurs and Domestic Carnivores in Eastern Madagascar
Journal of Zoo and Wildlife Medicine 47(1): 141–149, 2016 Copyright 2016 by American Association of Zoo Veterinarians GASTROINTESTINAL PARASITES OF CAPTIVE AND FREE-LIVING LEMURS AND DOMESTIC CARNIVORES IN EASTERN MADAGASCAR Amy B. Alexander, D.V.M., Cle´mence Poirotte, D.V.M., Ingrid J. Porton, M.S., Karen L.M. Freeman, Ph.D., Fidisoa Rasambainarivo, D.V.M., M.S., Kimberly G. Olson, R.V.T., Bernard Iambana, and Sharon L. Deem, D.V.M., Ph.D., Dipl. A.C.Z.M. Abstract: Fecal samples from captive and free-living lemurs at Ivoloina Zoological Park (IZP) and domestic carnivores from six villages surrounding IZP were evaluated between July and August 2012. Free-living lemurs from Betampona Natural Reserve (BNR), a relatively pristine rainforest fragment 40 km away, were also evaluated in November 2013. All 33 dogs sampled (100%) and 16 of 22 cats sampled (72.7%) were parasitized, predominantly with nematodes (strongyles, ascarids, and spirurids) as well as cestodes and protozoans. Similar types of parasites were identified in the lemur populations. Identification of spirurid nematodes and protozoans in the lemur fecal samples were of concern due to previously documented morbidity and mortality in lemurs from these parasitic agents. Twelve of 13 free-living (93%) and 31 of 49 captive (63%) lemurs sampled at IZP had a higher parasite prevalence than lemurs at BNR, with 13 of 24 (54%) being parasitized. The lemurs in BNR are likely at risk of increased exposure to these parasites and, therefore, increased morbidity and mortality, as humans and their domestic animals are encroaching on this natural area. -
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.

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. -

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. -

Living populations still persist, but in low numbers within a diminished range, making it one of the most critically endangered lemurs. Over the past twenty years scientists have searched the south- and central-eastern rain forests of Madagascar. Despite surveys that encompass over 500 km², less than 75 animals have been found, with a recent total count of 60. -
(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).
