What happens to the wildlife in patches of native vegetation when the surrounding agricultural landscape is converted from open grazed land to closed pine plantation forest? This is far from being an academic question as this situation is increasingly common as plantations are often established on cultivated or grazed land. Alessio Mortelliti and colleagues conducted […]
What happens to wildlife when farmland becomes a plantation?
Extinction, the disappearance of the last individual of a species, is rarely observed, is very difficult to detect and therefore usually must be inferred. And getting it right is important. Listing a species as extant (still in existence) when it is actually extinct is undesirable since it can lead to misallocation of funds, incorrect reporting […]
Which ‘books’ do you save as the library of life burns? The global extinction crisis shows no signs of abating, and conservation funding falls far short of what is necessary to stop declines in biodiversity. Thus, either implicitly or explicitly, conservation agencies engage in prioritization; they try to use their limited resources to maximize achievable […]
Where do you begin? They call it ‘the Galapagos of the Indian Ocean’, where golden bosun-birds soar over terraced limestone cliffs and the rainforest floor teems with millions of crabs – Christmas Island is truly like nowhere else in the world. But the island’s highly endemic fauna is under pressure. Four species of mammal have […]
‘Extinction risk’ is a powerful notion. If one species’ extinction risk is way higher than another species then there’s a strong argument to give it a greater share of the limited resources available for conservation. New research is suggesting, however, that there’s much we can do to improve the way we calculate extinction risk.
