FEATUREDCan cattle and wildlife co-exist in the Maasai Mara? A controversial study says yes byAshoka Mukpo — November 5, 2024- Conventional conservation wisdom has held that cattle herds managed by Indigenous Maasai in East Africa compete with wildlife for grazing land and degrade protected areas like Kenya’s Maasai Mara and Tanzania’s Ngorongoro. - But a new research study shows that, in a small study patch of the Maasai Mara, cattle herds didn’t cause a decline in forage quantity or quality, nor did wildlife steer away from areas where cattle had grazed. - The finding has drawn criticism from other researchers, who question its methodology and say the overwhelming evidence points to the need for restrictions on cattle grazing inside these protected areas. - The study authors say they hope their findings spark new thinking about how pastoralists like the Maasai can be seen as potential conservation partners rather than excluded as they’ve been for decades. Study finds bonobos more diverse, and more vulnerable, than previously thought byCharles Mpaka — November 4, 2024 - Recently published research finds that bonobos show a much deeper degree of genetic diversity than previously thought, with the species split into three distinct subgroups that diverged tens of thousands of years ago. - The study is based on a detailed analysis of the genomes of 30 wild-born captive bonobos, cross-referenced with more limited data from 136 wild bonobos. - Separation into three genetically isolated groups means that each group is more vulnerable than a single unified population would be, and that loss of any of these groups would result in a significant loss of the species’ genetic diversity. How a lineage of chiefs built a thriving fish oasis in Lake Malawi byCharles Mpaka — November 4, 2024 - Lake Malawi accounts for more than 90% of landlocked Malawi’s total fish catch, and a key fishing ground is the water around Mbenje Island. - The community here has since the 1950s practiced, and enforced, a fisheries management regime that continues to benefit both fishers and local fish stocks. - Even as fish stocks dwindle and average fish sizes shrink elsewhere across Lake Malawi, around Mbenje Island the fish are bigger and fishers are “assured [of] a good haul.” - The success of the management scheme is credited to the fact that it’s embedded within the community’s existing power structures, giving it “legitimacy among fishers as it has not been imposed from outside,” according to a researcher. New brown bear ‘stronghold’ in Nepal redraws species’ range map byAbhaya Raj Joshi — October 31, 2024 - A population of brown bears has been discovered in western Nepal, extending the species’ known geographical range and suggesting a potential “contact zone” between the Himalayan and Tibetan brown bear subspecies. - Researchers from the Himalayan Wolves Project discovered the bears during camera-trap studies in the Limi Valley, which is rich in biodiversity but has seen limited ecological research compared to other regions of Nepal. - The bears exhibit physical traits associated with the Tibetan subspecies, but genetic analysis is necessary to confirm their subspecies classification and determine if they’re hybrids. - Research indicates that habitat for brown bears in Nepal may shrink significantly due to climate change, with predictions showing up to 82% habitat loss by 2070 if global temperatures rise by 2.7°C (4.9°F) by end-century, emphasizing the urgent need for conservation efforts. muh usa edu. bs muh2 fav website mongabay oceanic saviopur no ww wamongers involved hiuh/duh |
