Chimpanzee population structure in Cameroon and Nigeria is associated with
habitat variation that may be lost under climate change

Abstract
Background
The Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) is found in the
Gulf of
Guinea biodiversity hotspot located in western equatorial Africa. This
subspecies is
threatened by habitat fragmentation due to logging and agricultural
development,
hunting for the bushmeat trade, and possibly climate change. Although P.
t. ellioti
appears to be geographically separated from the neighboring central
chimpanzee
(P. t. troglodytes) by the Sanaga River, recent population genetics
studies of
chimpanzees from across this region suggest that additional factors may
also be
important in their separation. The main aims of this study were: 1) to
model the
distribution of suitable habitat for P. t. ellioti across Cameroon and
Nigeria, and
P. t. troglodytes in southern Cameroon, 2) to determine which
environmental factors
best predict their optimal habitats, and 3) to compare modeled niches and
test for
their levels of divergence from one another. A final aim of this study was
to examine
the ways that climate change might impact suitable chimpanzee habitat
across the
region under various scenarios.

Conclusions
These findings suggest that a positive relationship may exist between
environmental
variation and the partitioning of genetic variation found in chimpanzees
across this
region. ENMs for each population were also projected under three different
climate
change scenarios for years 2020, 2050, and 2080. Suitable habitat of P. t.
ellioti in
northwest Cameroon / eastern Nigeria is expected to remain largely unchanged
through 2080 in all considered scenarios. In contrast, P. t. ellioti in
central Cameroon,
which represents half of the population of this subspecies, is expected to
experience
drastic reductions in its ecotone habitat over the coming century.

So how has the EXTENSIVE "climate change" seen throughout the Quaternary
Period -- roughly the last 2.6 million years or so -- altered the population
structure of Cameroon & Nigerian Chimpanzees?

Oh. I forgot; Gwobull Warbling is a religion. It's only in science where we can
question the answers...
