Sikkim, a place of great natural beauty, has been neglected by botanists and zoologists. While there is apprehension that many species have already become extinct or endangered, little is being done to conserve its biodiversity
Palaeontologists have found what they had been looking for: a near perfect dinosaur fossil from the Jurassic Age. They might finally be able to tell whether the creatures descended from birds or reptiles
It was huge. And it was heading straight for Earth. Astronomers said the end was here. Frantic revisions of their calculations later showed that asteroid XF11 would miss us. But what if there are others that don t alter course?
There are few controlled data with which to assess the conservation role of corridors connecting refuges. If corridors were used sufficiently, they could alleviate threats from inbreeding depression and demographic stochasticity. For species that require more resources than are available in single refuges, a network of refuges connected by corridors may allow persistence.
