Evolutionary history of the endangered Sanje mangabey (Cercocebus sanjei) in the Udzungwa Mountains, Tanzania
Understanding whether a species’ distribution results from recent and/or anthropogenic events or ancient vicariant factors is critical for conservation planning. The Endangered Sanje mangabey ( Cercocebus sanjei ), endemic to Tanzania’s Udzungwa Mountains, is currently divided into two populations located approximately 100 km apart. These represent distinct evolutionary lineages that diverged around 0.77 million years ago (MYA). We aimed to inves…
On the Phylogenetic History of the Sanje Mangabey (Cercocebus sanjei), Udzungwa Mountains, Tanzania
An accurate understanding of phylogeny, including intraspecific diversity, is key for defining conservation measures. The Sanje mangabey ( Cercocebus sanjei ) is an Endangered primate endemic to the Udzungwa Mountains in Tanzania that inhabits montane forest fragments and occurs in two populations—Mwanihana Forest and Uzungwa Scarp Nature Reserve—located 100 km apart. The phylogenetic position of the Sanje mangabey relative to other Cercocebus sp…
Effects of forest fragmentation on the dietary ecology and activity of a nocturnal lemur community in North West Madagascar
Deforestation and habitat fragmentation is the primary threat to primate populations. The primates that live within degraded and anthropogenically disturbed habitats typical of fragmented landscapes have to cope with lower availability of resources in comparison to primates in continuous, undisturbed forests. While some species are sensitive to forest fragmentation, some evidence exists to suggest that primates can alter their behavior and adapt …
Conservation Biogeography of the Dwarf Lemurs (Cheirogaleus) of Madagascar, Investigated via Ecological Niche Modelling
Ecological niches are the environmental conditions under which an organism can maintain viable populations. A detailed understanding of an organisms’ ecological niche can provide information on its taxonomy and biogeography, and ecological niche modelling allows researchers to investigate how closely-related species are able to coexist. Ecological niche models also enable conservationists to determine species’ habitat requirements, map distributi…
Seasonal Differences in the Encounter Rate of the Fat-Tailed Dwarf Lemur (Cheirogaleus medius) in the Transitional Forests of Northwest Madagascar
Primate encounter rates often vary throughout the year due to seasonal differences in activity, ecology, and behaviour. One notably extreme behaviour is continuous hibernation. Although a rare adaptation in primates, the dwarf lemurs of Madagascar (genus Cheirogaleus ) enter obligate hibernation each year during the dry season, after spending the wet season consuming high-energy foods. Whilst seasonal changes in activity in some Cheirogaleus popu…
Failure is the Greatest Teacher
“Failure” is recognised as being vital for success in many fields but is seldom embraced in primate conservation or conservation more generally. In this paper, we use examples from the literature, particularly around reintroduction, to reflect on failure and consider the contribution it can make to primate conservation success. Barriers to acknowledging failure are highlighted and include concerns regarding reputational damage that impact on comm…
The Current Status of the World’s Primates
Over the past decades, primate populations have been declining. Four years ago, >60% of species were listed as threatened. As the rate of loss accelerates and new IUCN assessments are being published, we used IUCN Red List assessments and peer-reviewed literature published within the last 5 yr to evaluate the status of primates globally, by region and by taxonomic group. We also examined the main factors affecting a species’ conservation status t…
Estimating the population size of the Sanje mangabey ( Cercocebus sanjei ) using acoustic distance sampling
The Sanje mangabey ( Cercocebus sanjei ) is endemic to the Udzungwa Mountains, Tanzania, and is classified as Endangered due to its putatively declining population size, habitat degradation and fragmentation. Previous population size estimates have ranged from 1,350 to 3,500 individuals, with the last direct survey being conducted 15 years before the present study. Previous estimates are now thought to have underestimated the population due to a …
Sleeping and Ranging Behavior of the Sambirano Mouse Lemur, Microcebus sambiranensis
Primates require secure sleeping sites for periods of rest, but despite their importance, the characteristics of desired sleeping sites are poorly known. Here we investigated the sleeping ecology of a radio-collared population of the Sambirano mouse lemur, Microcebus sambiranensis , during the nonreproductive season in the Anabohazo forest, northwestern Madagascar. We also investigated their ranging behavior and examined the spatial distribution …
The use of Vocalizations of the Sambirano Mouse Lemur (Microcebus sambiranensis) in an Acoustic Survey of Habitat Preference
Primate vocalizations convey a variety of information to conspecifics. The acoustic traits of these vocalizations are an effective vocal fingerprint to discriminate between sibling species for taxonomic diagnosis. However, the vocal behavior of nocturnal primates has been poorly studied and there are few studies of their vocal repertoires. We compiled a vocal repertoire for the Endangered Sambirano mouse lemur, Microcebus sambiranensis , an unstu…
Ecology of reproduction in Sanje mangabeys ( Cercocebus sanjei )
The ability to increase energy storage when food is abundant for later use during late gestation and early lactation is often considered the primary benefit of the capital breeding strategy (clustering conceptions during high food periods, HFP) that promotes reproductive success among females living in unpredictable environments. Capital breeding, however, may also enable preconceptive females to increase hormone production for ovulation, which h…
