A basic understanding of the taxonomy, diversity, and distributions of primates is essential for their conservation. This review of the status of the taxonomy of lemurs is based on a 5-d workshop entitled "Primate Taxonomy for the New Millennium," held at the Disney Institute, Orlando, Florida, in February 2000. The aim is not to present a taxonomic revision, but to review our current understanding of the diversity and current and past ranges of lemurs and indicate where there is controversy, discrepancy, or lack of knowledge. Our goal therefore is to provide a baseline for future taxonomic investigation, as well as a clearer focus for research Int J Primatol (2008) and conservation priorities. We here focus on the lemurs of Madagascar and recognize 5 families, 15 genera, and 99 species and subspecies. We list 39 species of lemurs described since 2000: 2 dwarf lemurs, Cheirogaleus; 11 mouse lemurs, Microcebus; a giant mouse lemur, Mirza; a bamboo lemur, Hapalemur; 17 sportive lemurs, Lepilemur; and 7 woolly lemurs, Avahi. Taxonomic revisions have resulted in the resurrection of a further 9 taxa. However, the figures do not represent the total diversity of Malagasy lemurs because more new species are being identified via new field studies and accompanying genetic research, and should be described in the near future.

“…Dietary plasticity, as found in Lemur catta , is suggested to be a key feature enabling the species to persist in the face of resource fluctuations due to natural disasters Sauther et al, 1999]. The variation in ecological adaptability of L. catta may be exemplified through the wide range of habitat types in which it is found: spiny and gallery forests, scrub and brush land, anthropogenically induced savannah, and ericoid bush/subalpine habitat [Goodman and Langrand, 1996;Goodman and Rasolonandrasana, 2001;Sussman et al, 2003;Goodman et al, 2006;Gould, 2006], especially considering that L. catta is thought to have evolved in dry habitats of south and southwest Madagascar [Goodman et al, 2006]. Although its resource base is flexible, L. catta reproduction is highly tied to seasonal resources [Jolly, 1984;Sauther, 1992;Rasamimanana and Rafidinarivo, 1993;Sauther, 1993Sauther, , 1998Yamashita, 2002].…”

In January 2005, a cyclone hit southern Madagascar, including the Beza Mahafaly Special Reserve, disrupting the flowering/fruiting cycle of Tamarindus indica, leaving Lemur catta without its major food resource during reproductive periods. We studied two adjacent groups of L. catta during the late gestation period, and both groups ventured outside the reserve to feed. The Red group (RG) fed daily on cultivated sweet potato (Ipomoea batatas) leaves in a nearby field, and both groups consumed leaves and stems of the invasive terrestrial flowering herb Mexican prickly poppy (Argemone mexicana), growing outside the reserve. The Green group (GG) spent significantly more time feeding than did RG, and more time feeding inside the forest compared to outside. The members of RG spent half of their time feeding in the crops, and nearly half of their diet consisted of easy-to-process sweet potato leaves. Additionally, RG defended and restricted GG’s access to the crop territory. Of the two non-forest foods, A. mexicana leaves were higher in protein and most minerals (P, Mg, K and Na, but not Ca) and lower in fiber than sweet potato leaves, but sweet potato leaves were preferred by RG. L. catta is a markedly flexible primate with respect to diet, and switches to fallback foods from outside the forest during periods of low food availability. In the highly seasonal and unpredictable climate of southern Madagascar, such behavioral adaptations are important to the survival of this species.

Although data quality and weighting decisions impact the outputs of reserve selection algorithms, these factors have not been closely studied. We examine these methodological issues in the use of reserve selection algorithms by comparing: (1) quality of input data and (2) use of different weighting methods for prioritizing among species. In 2003, the government of Madagascar, a global biodiversity hotspot, committed to tripling the size of its protected area network to protect 10% of the country's total land area. We apply the Zonation reserve selection algorithm to distribution data for 52 lemur species to identify priority areas for the expansion of Madagascar's reserve network. We assess the similarity of the areas selected, as well as the proportions of lemur ranges protected in the resulting areas when different forms of input data were used: extent of occurrence versus refined extent of occurrence. Low overlap between the areas selected suggests that refined extent of occurrence data are highly desirable, and to best protect lemur species, we recommend refining extent of occurrence ranges using habitat and altitude limitations. Reserve areas were also selected for protection based on three different species weighting schemes, resulting in marked variation in proportional representation of species among the IUCN Red List of Threatened Species extinction risk categories. This result demonstrates that assignment of species weights influences whether a reserve network prioritizes maximizing overall species protection or maximizing protection of the most threatened species.
