Abstract/Description
From October-December 2013, we conducted a study of the newly discovered primate species lesula, Cercopithecus lomamiensis, in the DR Congo. We placed 41 camera traps inside a 4 km2 grid outside the proposed Lomami National Park (LNP). We compared an analysis of 140 lesula events over 1,683 camera trap days from the heavily hunted Okulu area to a pilot study (38 events over 462 camera trap days) at the Losekola study site within the LNP. Our data show an unexpected result: capture probability...

We placed 41 camera traps inside a 4 km2 grid outside the proposed Lomami National Park (LNP). We compared an analysis of 140 lesula events over 1,683 camera trap days from the heavily hunted Okulu area to a pilot study (38 events over 462 camera trap days) at the Losekola study site within the LNP. Our data show an unexpected result: capture probability of lesula (0.08) is the same at both the hunted and non-hunted sites. This is in contrast to the sharp decline in capture probability of all other medium-to-large terrestrial mammals at the Okulu site. These findings suggest lesula’s cryptic behavior is an important adaptation buffering the species from the impacts of hunting. This study also expands knowledge on minimum group size, terrestriality, diet, and times of activity.

A Conservation Genetic Study of Cercopithecus mitis in the Lomami Basin, Democratic Republic of the Congo

A Conservation Genetic Study of Cercopithecus mitis in the Lomami Basin, Democratic Republic of the Congo.

Abstract/Description
The Cercopithecus mitis radiation has significant phenotypic and ecological diversity, making it a great candidate for evolutionary genetic studies. This study represents the first genetic survey of C. mitis from well provenanced wild populations, including C. mitis heymansi from the TL2 landscape, an area of remote tropical forest between the Tshuapa, Lomami, and Lualaba rivers in the Democratic Republic of the Congo. Tissue samples were collected from 7 male blue monkeys, DNA was extracted...

This study represents the first genetic survey of C. mitis from well provenanced wild populations, including C. mitis heymansi from the TL2 landscape, an area of remote tropical forest between the Tshuapa, Lomami, and Lualaba rivers in the Democratic Republic of the Congo. Tissue samples were collected from 7 male blue monkeys, DNA was extracted and surveyed at 919 bp of the Testis-Specific Protein Y-chromosome (TSPY), and added to a larger dataset including other C. mitis and C. albogularis specimens. Evolutionary analyses suggests TL2 C. mitis shared recent genetic contact with C. albogularis at the headwaters of the Congo River than with conspecifics to the northeast, indicating the Congo River is a significant biogeographic barrier to C. mitis and sheds new light on their genetic heritage, taxonomic assignment, and conservation status.

Abstract/Description
In 2012, a new monkey species, Cercopithecus lomamiensis (lesula), was discovered in the Central Congo basin. Lesula is a semi-terrestrial rainforest guenon endemic to the area. Using a systematic grid approach, three terrestrial camera trap surveys (two inside the Lomami National Park; one in the buffer zone) were conducted over three years to capture the cryptic species. The objectives of my study were to expand knowledge on the behavioral ecology of lesula and evaluate lesula’s sensitivity...

Using a systematic grid approach, three terrestrial camera trap surveys (two inside the Lomami National Park; one in the buffer zone) were conducted over three years to capture the cryptic species. The objectives of my study were to expand knowledge on the behavioral ecology of lesula and evaluate lesula’s sensitivity to hunting threats. The main findings from my study included: confirmation of terrestriality and diurnality, births clustering during the wet season, social group living of one male and multiple females, and high impact of hunting on group size. By studying the latest added species to the Cercopithecini tribe, my thesis helps to better understand the ecological diversity occurring within this radiation of African primates and contributes to the species’ long-term conservation efforts.
