Satellite data analysis suggests climate-induced algal blooms could be behind hundreds of deaths in Botswana that sparked flurry of theories in 2020

More than 350 elephants that died in mysterious circumstances probably drank toxic water, according to a new paper that warns of an “alarming trend” in climate-induced poisoning.

Significance

Despite the conservation importance of documenting temporal population trends of African elephants, we lack a comprehensive assessment of recent changes in the world’s largest terrestrial mammal. This assessment summarizes site-level trends in density over five decades from hundreds of surveys conducted across Africa on the forest and savannah elephant species. Both species have experienced substantial declines at the majority of survey sites. Forest elephant sites have declined on average by 90%, whereas savanna elephant sites have declined by 70% over the study period. However, savannah elephants have also demonstrated some increases, indicating that the threats and challenges elephants face are not the same everywhere. From the successes, we can learn how to better protect elephants across their range.

• The recent killing of a jaguar by hunters increases the species’ risk of extinction in Argentina’s Gran Chaco landscape, where no more than 10 of the big cats are thought remain.

• Images of this particular jaguar were captured by camera trap twice this year as it traveled through a biological corridor; the next time it was photographed was on social media, where hunters posed with its carcass and its pelt.

• A tradition of hunting, lack of public awareness, persistent deforestation, and absence of female jaguars — there’s only one, recently rewilded into the area — are the biggest obstacles to the jaguar’s survival in the Argentine Gran Chaco.

What’s new: The first ever camera trap study from Cambodia’s Central Cardamom Mountains has captured footage of 108 wildlife species, including 23 that are threatened with extinction. This survey confirms the area’s importance as a biodiversity hotspot, a recent report says.

Conservationists and a Native American advocacy group are suing to block a Nevada lithium mine they say will drive an endangered wildflower to extinction.
