To save biodiversity, on-the-ground agencies need to set the conservation research agenda, not distant academics and non-governmental organizations, argue Robert J. Smith and colleagues.
Palaeontologists must model the causes of biodiversity rather than simply cataloguing fossils, says Douglas Erwin, as they curate the only record of ecosystems undamaged by humans.
camera traps work well to estimate species diversity of medium and large mammals, a recent study says. Counting the number of mammals in dense tropical forests is difficult and rare species are often missed out. Camera traps offer a new tool for finding the number of large and medium sized terrestrial mammals. But the method is not foolproof and researchers point out the importance of having an
