Chimpanzees (Pan troglodytes) can be divided into four subspecies. Substantial phylogenetic evidence suggests that these subspecies can be grouped into two distinct lineages: a western African group that includes P. t. verus and P. t. ellioti and a central/eastern African group that includes P. t. troglodytes and P. t. schweinfurthii. The geographic division of these two lineages occurs in Cameroon, where the rages of P. t. ellioti and P. t. troglodytes appear to converge at the Sanaga River. Remarkably, few population genetic studies have included wild chimpanzees from this region.

Working with the Rainforest Alliance, Chiquita’s active biodiversity program goes beyond the boundaries of its banana farms.

What is Ebola virus disease?

Monkeys near the stricken Fukushima nuclear power plant have lower blood cell counts than cousins living further away, possibly because of radiation exposure, a study says.

The Cameroon-Nigeria border region where the Cross River gorilla occurs is a biodiversity hotspot of global significance. The Cross River gorilla can therefore play a role as a ‘flagship’ species; the actions proposed in this plan ensure the survival of both this Critically Endangered ape and the region’s immense biological wealth.

Conflicts between humans and non-human primates are recognized as major issues in conservation of primates. Crop damage caused by primates is one of the most wide spread and common examples of human-nonhuman primate conflicts in areas where local people are mainly subsistence farmers. Various forms of human-wildlife conflicts occur with various negative results, including damage to crops and property, habitat destruction, injuries and death of people and wildlife, and livestock depredation.

Pluripotent stem cells provide a potential solution to current epidemic rates of heart failure by providing human cardiomyocytes to support heart regeneration. Studies of human embryonic-stem-cell-derived cardiomyocytes (hESC-CMs) in small-animal models have shown favourable effects of this treatment. However, it remains unknown whether clinical-scale hESC-CM transplantation is feasible, safe or can provide sufficient myocardial regeneration. Here we show that hESC-CMs can be produced at a clinical scale (more than one billion cells per batch) and cryopreserved with good viability.

A group of volunteers from a city-based environmental group, who ventured into Sirumalai Reserve Forest recently, have come out with shocking impact of summer heat on animals.
