The number of seagulls in the Strait of Georgia is down by 50 per cent from the 1980s and researchers say the decline reflects changes in the availability of food.
Tigers, lions and other wild carnivores, already under threat from poaching and habitat loss, are falling victim to Canine distemper, and could soon drive endangered populations to extinction.
The chytrid fungus, which is fatal to amphibians, has been detected in Madagascar for the first time. This means that the chytridiomycosis pandemic has now reached a biodiversity hotspot. Researchers are therefore proposing an emergency plan. This includes monitoring the spread of the pathogenic fungus, building amphibian breeding stations and developing probiotic treatments, say the scientists.
