Abstract:

Three elephant taxa remain from the sixteen elephant-like species that are known from across the planet in the Pleistocene: Asian Elephant (Elephas maximus), African Savanna Elephant (Loxodonta africana), and African Forest Elephant (Loxodonta cyclotis) (Faurby and Svenning 2015, Malhi et al. 2016). The Asian and African ancestral lineages diverged approximately seven million years ago, and the African Savanna and African Forest ancestral lineages began diverging approximately one million years later (Rohland et al. 2010, Brandt et al. 2014, Roca et al. 2015, Meyer et al. 2017, Palkopoulou et al. 2018). The Third Edition of ‘Mammal Species of the World’ (Wilson and Reeder 2005) was the first to formally designate the African elephant as these two separate species. Recent genetic findings also support this designation (Roca et al. 2007, Ishida et al. 2011, Mondol et al. 2015, Palkopoulou et al. 2018, Kim and Wasser 2019). Hybridization between the two species appears restricted and evident at only 14 of the more than 100 localities recently examined across the vast forest-savanna ecotone. In nine of these 14 localities, hybrid individuals occurred alongside non-hybrid individuals of either one species or the other and not both (i.e., three localities had hybrids and African Forest Elephants only and assigned as this species; six localities had hybrids and African Savanna Elephants only and assigned as this species). For the IUCN Red List assessments, a distribution map published in Mondol et al. (2015) and recent data by Kim and Wasser (2019) are used to assign localities as range of either L. africana or L. cyclotis.
