Rhino killings on the rise in South Africa by AFP Staff Writers Johannesburg (AFP) July 31, 2021 At least 249 rhinos were killed the first six months of this year in South Africa, the environment minister said Saturday, partly pushed by the easing of lockdown curbs that increased movement of poachers. South Africa is home to nearly 80 percent of the world's rhinos but their horns are prized in traditional medicine in Asia, and poachers have continued to mount an onslaught on the species. The figure represents 83 more rhino killings compared with the same period in 2020. The bulk of the slaughter happened at the famed Kruger National Park where 132 rhinos were killed. "From January to the end of June 2021, 249 rhino have been poached for their horn in South Africa," said Barbara Creecy, the minister of environment, forestry and fisheries in a statement. Creecy said lifting the stringent lockdown "appears to have seen an increase in rhino poaching in the first six months of 2021", with noticeable increased poacher pressure in the Limpopo, Mpumalanga and the Free State provinces where a large number of private rhino reserves are found. The ministry said it was monitoring the increased pressure seen on private rhino reserves as they play a significant role in rhino protection. Rhinos are killed for their horns, highly prized across Asia for traditional and medicinal purposes. The trade is lucrative and thousands of rhinos have been poached in South Africa over the past decade. Usually sold in powdered form, rhino horn is composed mainly of keratin, the same substance as in human fingernails.
Without genetic variation, asexual invasive species find other ways to adapt Washington DC (UPI) Jul 30, 2021 Invasive all-female weevils pass along epigenetic changes to their offspring, helping them adapt to new environs, according to a new study. Across most of the animal kingdom, an organism's ability to adapt and evolve is largely dependent on genetic variation. Sufficient genetic diversity makes it more likely that favorable traits will emerge and proliferate as the fittest specimens populate subsequent generations. Some species, however, reproduce asexually, which means their genet ... read more
