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 Madagascar 1 (Table 1). Today the equivalent figures are $7.40, $95, and 83 lemur species 2 (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… 
Understanding species - level primate diversity in Madagascar
TLDR
It is argued here that the reflexive wholesale application of the Phylogenetic Species Concept to Madagascar’s lemurs is inappropriate, and that a return to biological species concepts, and to the corresponding criteria for species recognition, will allow us to attain a much fuller and more nuanced appreciation of lemur diversity at low taxonomic levels.
Lemur Diversity in Madagascar
TLDR
The aim is to provide a baseline for future taxonomic investigation, as well as a clearer focus for research and conservation priorities, and to review the current understanding of the diversity and current and past ranges of lemurs and indicate where there is controversy, discrepancy, or lack of knowledge.
Madagascar: A History of Arrivals, What Happened, and Will Happen Next*
TLDR
Three themes in this review bear on the future: the continuing impact of recent, cataclysmic events on modern communities of people, plants, and animals; Madagascar's long and dynamic environmental history; and the complicated history of how people settled and interacted with the island's landscapes.
Neanderthals, Homo sapiens, and the question of species in paleoanthropology
TLDR
The Neanderthals appear not simply to constitute a separate species lineage, but to form part of a larger endemic European clade to which such distinctive forms as the Sima de los Huesos and Steinheim fossils also belong, showing that hominid history in this region is more complex.
Species-Level Diversity Among Malagasy Lemurs
TLDR
It is argued that “silver-bullet” approaches to species recognition ignore real biological complexity, and that species are best recognized through weighing all available evidence including that furnished by morphology, molecules, behavior, communication, demography, and distributions.
So what is a species anyway? A primatological perspective
TLDR
The great interest in what a species is reflects the importance of “species” as fundamental units in most fields of biology, especially evolutionary biology, ecology, and conservation.
The lemur revolution starts now: the genomic coming of age for a non-model organism.

Testing the adaptive radiation hypothesis for the lemurs of Madagascar
TLDR
Based on the most complete phylogeny of living and extinct lemurs yet assembled, predictions of adaptive radiation theory are tested by estimating rates of speciation, extinction and adaptive phenotypic evolution, with lemur speciation rate exceeding that of their sister clade by nearly twofold.
Speciation in Malagasy lemurs: a review of the cryptic diversity in genus Lepilemur
TLDR
An overview of the current knowledge of the genus Lepilemur is given, three biogeography models related to lemurs distribution are summarized and compared in order to understand the reasons behind the high diversity among the species in the genus.

TLDR
Overall, it now seems that primates originated at around 90 Ma rather than the 55 Ma indicated by direct reading of the known fossil record, and colonization of Madagascar by lemurs would have taken place at about 80 Ma, double the date usually accepted, and should be interpreted in terms of contemporary continental relationships.

A molecular approach to comparative phylogeography of extant Malagasy lemurs
TLDR
Genetic data show no significant differentiation between Malagasy and Comorian populations of these species, supporting the interpretation that both were introduced only recently to the Comoro Islands.
Notes on the Distribution and Taxonomic Status of Some Subspecies of Propithecus in Madagascar
I review the distributions of, and chromatic variation within, two subspecies pairs of the lemur species Propithecus diadema and P. verreauxi, in east-central and western Madagascar, respectively. On
Remarkable species diversity in Malagasy mouse lemurs (primates, Microcebus).
TLDR
Phylogenetic analysis of mtDNA sequence data confirms the observation that species diversity in the world's smallest living primate (genus Microcebus) has been greatly underestimated and revises established hypotheses of ecogeographic constraint for the maintenance of species boundaries in these endemic Malagasy primates.
Taxonomic Revision of Mouse Lemurs (Microcebus) in the Western Portions of Madagascar
TLDR
Seven species of Microcebus from western Madagascar are recognized, including a previously synonymized species, and 3 spp.
The Genus Cheirogaleus: Unrecognized Biodiversity in Dwarf Lemurs
  • C. Groves
  • Biology
    International Journal of Primatology
  • 2004
TLDR
A species previously known only from the type series, Cheirogaleus sibreei, and two new species, one sympatric with C. major and one, apparently allopatric to all others, from the central plateau are described.
Do Ruffed Lemurs Form a Hybrid Zone? Distribution and Discovery of Varecia, with Systematic and Conservation Implications
TLDR
The evidence for a natural hybrid zone is examined, and a more extensive hybrid zone than previously suggested is indicated—but one in which hybridization is the exception rather than the rule.
Taxonomic inflation and the stability of species lists: the perils of ostrich's behavior.
TLDR
The consequences of taxonomic progress on macroecology and conservation biology, two disciplines that heavily rely on species lists, and a broader application of the biological species concept (BSC) are explored.
Biogeography of Dwarf Lemurs: Genetic Evidence for Unexpected Patterns in Southeastern Madagascar
TLDR
It is proposed to identify an isolated population of dwarf lemurs in southeastern Madagascar as Cheirogaleus crossleyi and discuss the population genetic and biogeographic considerations supporting this conclusion.
