The population of rainforest elephants was lower than anticipated, at around 214,000 individuals. Between 1977 and 1989, elephant populations declined by 74% in East Africa. 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 ...
African forest elephants in a waterhole Group of African forest elephants digging at a mineral lick A female with her calf drinking from a spring. The African forest elephant lives in family groups. Groups observed in the rain forest of Gabon's Lopé National Park between 1984 and 1991 comprised between three and eight individuals. [27]
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]
It turns out that elephants actually do have a better memory than most living things. All mammals, including humans, have four different lobes in their cortex: occipital, parietal, temporal, and ...
Mature fully grown females are smaller at about 2.60 m (8 ft 6 in) tall at the shoulder and 3.0 t (3.3 short tons) in weight on average under optimal growth conditions (with 90% of fully grown females ranging between 2.47–2.73 m (8 ft 1 in – 8 ft 11 in) and 2.6–3.5 t (2.9–3.9 short tons) in optimal conditions).
Time and distance do not seem to impact their memories, indicating excellent long-term retention. Because elephants can live for 60 years in the wild, this leads to an incredible build-up of ...
This denied the enemy elephantry the wide, open, flat spaces it needed to operate in large, coordinated formations and made it easier to isolate and pick off elephants one at a time.
Elephants are drawn to large parties present at forest clearings, and remain in the clearing for a longer period of time if there are individuals outside of their party present. Young African male elephants display a preference for larger groups, in order to communicate with other elephants and to explore dominance. [ 7 ]
