The vast majority of lemur species are on the edge of extinction, experts warn. But not every lemur species faces a grim future. There may be as many as 1.3 million white-fronted brown lemurs still in the wild, for example, and mouse lemurs may number more than 2 million, a Duke-led study has shown.

A suppository form of the common antimalarial artesunate has dramatically cut child deaths from severe malaria in a trial in rural Zambia, one of the organisations behind the programme has said.

A new paper reviews current knowledge on climate change and biodiversity. In the past, plants and animals reacted to environmental changes by adapting, migrating or going extinct. These findings point to radical changes in biodiversity due to climate change in the future. The paper is published in the scientific journal Trends in Ecology and Evolution by an international group of scientists led by the Center for Macroecology, Evolution and Climate, University of Copenhagen.

Cattle or sheep grazing on pastures where the parasite is present can become infected with liver fluke, which develops in the liver of infected animals, leading to a disease called fascioliasis. Current estimates suggest liver fluke contributes to around £300 million annually in lost productivity across UK farms and $3 billion globally.

A new method of monitoring bird populations that takes into account changes in their songs over time could help scientists understand why some species are declining in the boreal forest.
