Management Population models Population viability analysis Propithecus edwardsi Lemurs Madagascar A B S T R A C T Madagascar ranks as one of the world's top extinction hotspots because of its high ende-mism and high rate of habitat degradation. Global climate phenomena such as El Niñ o Southern Oscillations may have confounding impacts on the island's(More)
The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon. With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human(More)
Globally, priority areas for biodiversity are relatively well known, yet few detailed plans exist to direct conservation action within them, despite urgent need. Madagascar, like other globally recognized biodiversity hot spots, has complex spatial patterns of endemism that differ among taxonomic groups, creating challenges for the selection of(More)
There are many criteria for evaluating hypertext. Adequacy and cost effectiveness are perhaps the most obvious flom the producer's perspective additional criteria are important for users. Examination of the limitations of various assessment criteria highlights the twin issues of the cognitive costs and benefits experienced by people using hypertext as part(More)
Social and ecological factors are important in shaping sexual dimorphism in Anthropoidea, but there is also a tendency for body-size dimorphism and canine dimorphism to increase with increased body size (Rensch's rule) (Rensch: Evolution Above the Species Level. London: Methuen, 1959.) Most ecologist interpret Rensch's rule to be a consequence of social and(More)
842 POLICYFORUM T he most threatened mammal group on Earth, Madagascar's fi ve endemic lemur families (lemurs are found nowhere else) (1), represent more than 20% of the world's primate species and 30% of family-level diversity. This combination of diversity and uniqueness is unmatched by any other country—remarkable considering that Madagascar is only 1.3(More)
In this research, we focused on aye-aye populations in Ranomafana National Park, Madagascar. From August to December 2008, we tested how aye-aye feeding was influenced by presence/absence of both fruiting and non-fruiting Canarium trees. Deadwood feeding traces were used as a proxy for evidence of Canarium feeding. We enumerated deadwood feeding traces in(More)
