After 1987, losses in elephant numbers hastened, and savannah populations from Cameroon to Somalia experienced a decline of 80%. African forest elephants had a total loss ...
Analysis of nuclear DNA sequences indicates that the genetic divergence between African bush and forest elephants dates 2.6 – 5.6 million years ago. The African forest elephant was found to have a high degree of genetic diversity, likely reflecting periodic fragmentation of their habitat during the changes in the Pleistocene. [12]
The upper catchment of Ulu Segama Forest Reserve had the highest density of elephants with 3.69 elephants per 1 km 2 (0.39 sq mi). Only the unprotected central forest area supported an elephant population of more than 1,000 individuals.
Elephants may also be host for a variety of parasites and bacteria such as Pasteurella, [86] Salmonella, Clostridium, [87] coccidian, nematode, and trematode. [88] The elephant endotheliotropic herpesvirus (EEHV) is a member of the Proboscivirus genus, a novel clade most closely related to the mammalian betaherpesviruses . [ 89 ]
It is conjectured that about 1,000 elephants historically roamed the Outeniqua/Tsitsikamma area. [2] A 2006 DNA analysis of dung samples revealed the presence of at least 5 cows and possibly some bulls and calves, [1] moving within an area of 60,000 hectares of forest managed by SANParks – the only unfenced elephant group in South Africa ...
