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.

“…They also argued on morphological grounds against the suggested synonymy of P. tattersalli with P. v. coquereli. Mayor et al 69 followed with molecular, cytogenetic, and morphological analyses that suggested three clades within Propithecus: P. v. verreauxi; the four P. diadema taxa; and P. tattersalli þ P. v. coquereli.

“…Their sample did not include P. v. coronatus/deckeni. Elevating all of the P. diadema subspecies to species level, Mayor et al 69 recognized seven species among those taxa sampled, albeit using a highly restrictive variant of the PSC based purely on diagnosability. Mittermeier et al, 2 using a ''precautionary principle,'' adopted a similar schema, with the addition of both P. deckenii and P. coronatus, while noting the possibility that yet more Propithecus species remained unnamed.…”

Madagascar's Lemurs: Cryptic diversity or taxonomic inflation?

We live in inflationary times. A quarter of a century ago, cigarettes were about $1 a pack in New York City, a bottle of Château Beaucastel set you back $15, and there were 36 different species of lemur alive in Madagascar1 (Table 1). Today the equivalent figures are $7.40, $95, and 83 lemur species2 (Table 1). The increase in dollar prices has a lot to do with the economics of growth, something that obviously cannot be sustained indefinitely on a finite planet. Is the recent inflation in lemur taxonomy any more secure? The question is all the more worth asking because this is no isolated phenomenon: Madagascar's primates have not been alone in multiplying. The same burgeoning of species names has occurred throughout the order Primates3, 4 and beyond,5 provoking both concern and energetic debate.6–9 Interestingly, this debate has largely unfolded among ecologists, conservationists, and other “consumers” of taxonomy; many “producers” seem to be content to generate new taxonomies with a remarkable lack of introspection, as if they were no more than passive consequences of more lofty concerns. And because the same causes underlie taxonomic inflation in Madagascar as elsewhere, this extraordinary island once again presents us with a microcosm of the larger world.

Living in forest fragments reduces group cohesion in diademed sifakas (Propithecus diadema) in eastern Madagascar by reducing food patch size

Forest fragmentation is thought to threaten primate populations, yet the mechanisms by which this occurs remain largely unknown. However, fragmentation is known to cause dietary shifts in several primate species, and links between food resource distribution and within-group spatial dynamics are well documented. Thus, fragmentation has the potential to indirectly affect spatial dynamics, and these changes may present additional stresses to fragmented populations. I present the results from a 12-month study of Propithecus diadema at Tsinjoarivo, eastern Madagascar, including two groups in fragments and two in continuous forest. Instantaneous data on activity and spatial position were collected during all-day focal animal follows. Fragment groups had much lower cohesion, being more likely to have no neighbor within 5 and 10 m. For continuous forest groups, cohesion was highest in the rainy season (when food patches are large) and lowest in winter (when the animals rely on small-crowned mistletoes), and the chance of having no neighbor within 5 m was positively correlated with mistletoe consumption. Thus their decreased cohesion in fragment groups is inferred to result from their increased reliance on mistletoes and other small resources, which causes them to spread out among multiple patches. This scenario is consistent with the reduced body mass of subordinate individuals (males and immatures) in fragments, and suggests the occurrence of steeper within-group fitness gradients. Further research is necessary to determine whether these patterns apply to other primates; however, since fragmentation tends to cause the loss of the largest trees, many primates in fragments may lose their largest food resources and undergo similar behavioral shifts.
