African elephant genomes reveal a past of continental connectivity and a future of increasing isolation

Genomics Habitat Fragmentation Conservation Biology

An international team of researchers conducted a large-scale genomic study of African savanna and forest elephants to analyze their historical connectivity and current genetic isolation. The findings suggest that habitat fragmentation and human activity are leading to inbreeding in some populations, highlighting the need for ecological corridors to maintain genetic health.
