Averting Lemur Extinctions amid Madagascar's Political Crisis
Community-based management, ecotourism, and researchers' presence are proposed to prevent lemur extinctions and reasons for hope are discussed in light of site-specific, local actions proposed in an emergency conservation action plan.
On the origins and admixture of Malagasy: new evidence from high-resolution analyses of paternal and maternal lineages.
This paper fits the Malagasy admixture history in a highly resolved phylogeographic framework by typing a large set of mitochondrial DNA and Y DNA markers in unrelated individuals from inland and coastal ethnic groups, allowing performance of a multilevel analysis in which the diversity among main ethnic divisions, lineage ancestries, and modes of inheritance could be concurrently evaluated.
(Un-)expected nocturnal activity in "Diurnal" Lemur catta supports cathemerality as one of the key adaptations of the lemurid radiation.
It is shown that the ring-tailed lemur, Lemur catta, a species previously considered to be diurnal, can in fact be cathemeral in the wild and the results confirm the relationship between transitional eye anatomy and physiology and 24-h activity, thus supporting the adaptive scenario.
Cathemeral Activity of Red-Fronted Brown Lemurs (Eulemur Fulvus Rufus) in the Kirindy Forest/CFPF
Results suggest that during the dry season less cover is provided by vegetation, these results suggest that the animals avoided diurnal exposure in the canopy and compensated for it with an increase of nocturnal foraging, especially during a full moon.
Influence of Abiotic Factors on Cathemeral Activity: The Case of Eulemur fulvus collaris in the Littoral Forest of Madagascar
The activity of collared brown lemurs appears to be seasonally influenced by photoperiod and directly modulated by nocturnal ambient luminosity, discussed by comparing data from other cathemeral species living in various climatic situations.
Better Few than Hungry: Flexible Feeding Ecology of Collared Lemurs Eulemur collaris in Littoral Forest Fragments
The findings indicate that collared lemurs in littoral forest fragments modified their behavior to cope with the pressures of fluctuating resource availability, likely to be an adaptation to Malagasy rainforests, which is known to undergo periods of fruit scarcity and low productivity.
Effects of Habitat Quality and Seasonality on Ranging Patterns of Collared Brown Lemur (Eulemur collaris) in Littoral Forest Fragments
Degraded forest habitats typically show low fruit availability and scattered fruit tree distribution. This has been shown to force frugivorous primates either to move further in search of food,
Proximate and ultimate determinants of cathemeral activity in brown lemurs
Diet quality was the only ultimate factor that had a significant effect on the diurnality index of the two lemur populations, suggesting a role of metabolic dietary-related needs in determining cathemeral activity in these lemurs.
Primate conservation: measuring and mitigating trade in primates
A series of studies dealing with various aspects of the primate trade are introduced, hoping that these studies will urge others to quantify the extent of trade in primates alive and dead in both domestic and international contexts, allowing us to find ways to mitigate the consequences of this trade to the conservation of primates.
Mineralogical composition of the clay bodies used in the Italian tile industry
Abstract The aim of this study is to differentiate mineralogically the clay bodies employed at present in Italian ceramic tile production. A collection of sixteen representative samples of various
