The effect of extreme weather events on hair cortisol and body weight in a wild ring‐tailed lemur population ( Lemur catta ) in southwestern Madagascar
Madagascar is known for its hypervariable climate with periodic droughts and cyclones, but little is known of the impact of such events on lemur physiology. We examined the effects of sequential weather periods, drought, normal, cyclone and post-cyclone, on hair cortisol concentrations (HCC) and body weight in wild ring-tailed lemurs, Lemur catta (n = 185), at the Bezà Mahafaly Special Reserve in southwestern Madagascar. Data were modeled and ana…
Paternity in wild ring‐tailed lemurs ( Lemur catta )
In group-living species with male dominance hierarchies where receptive periods of females do not overlap, high male reproductive skew would be predicted. However, the existence of female multiple mating and alternative male mating strategies can call into question single-male monopolization of paternity in groups. Ring-tailed lemurs (Lemur catta) are seasonally breeding primates that live in multi-male, multi-female groups. Although established …
Evaluating ring‐tailed lemurs ( Lemur catta ) from southwestern Madagascar for a genetic population bottleneck
In light of historical and recent anthropogenic influences on Malagasy primate populations, in this study ring‐tailed lemur ( Lemur catta ) samples from two sites in southwestern Madagascar, Beza Mahafaly Special Reserve (BMSR) and Tsimanampetsotsa National Park (TNP), were evaluated for the genetic signature of a population bottleneck. A total of 45 individuals (20 from BMSR and 25 from TNP) were genotyped at seven microsatellite loci. Three met…
Assessment of organochlorine pesticides and metals in ring‐tailed lemurs ( Lemur catta ) at Beza Mahafaly Special Reserve, Madagascar
Like most of Madagascar's endemic primates, ring‐tailed lemurs ( Lemur catta ) face a number of threats to their survival. Although habitat loss is of greatest concern, other anthropogenic factors including environmental contamination may also affect lemur health and survival. In this study, we examined ring‐tailed lemurs from the Beza Mahafaly Special Reserve (BMSR), southern Madagascar for exposure to organochlorine (OC) pesticides and metals a…
