As summer and autumn sea ice diminishes in the Arctic Sea, polar bears spending more time on shore have been spotted eating eggs, hunting down the nesting birds that lay them, hunting other land animals and even chewing on edible plants growing onshore. But is that enough to sustain them in an ice-scarce Arctic? No, says a new study.
LOS ANGELES -- A recent study has revealed 30 previously unknown species of flies, living right here in the bustling city of Los Angeles. This is remarkable because we usually don't think of urbanized areas as being particularly biologically diverse. But our lack of information on urban environments has allowed for an interesting research opportunity. A few years ago, the Natural History Museum of Los Angeles County initiated a project called BioSCAN to search for biodiversity in heavily urbanized areas.
The Chinese river dolphin has disappeared before our eyes within only two generations. Will we change course before other branches on the tree of life die off? It would be foolish to assume that we can somehow maintain our prosperity and our very future without the rich biodiversity on Planet Earth.
