摘要：Human-driven Arctic warming and resulting sea ice loss have been associated with declines in several polar bear populations. However, quantifying how individual responses to environmental change integrate and scale to influence population dynamics in polar bears has yet to be achieved. We developed an individual-based bioenergetic model and hindcast population dynamics across 42 years of observed sea ice conditions in Western Hudson Bay, a region undergoing rapid environmental change. The mode...

摘要：In February 1975, leading molecular biologists gathered at the Asilomar conference center on the California coast to evaluate risks of the emerging technology of recombinant DNA and to establish guidelines to govern research. The meeting is remembered as a defining moment in the making of molecular biology. Yet its legacy lies not in specific rules it developed but in the approach to scientific self-regulation that it crystallized. Five decades later, this near-mythic meeting that changed the ...

摘要：Recovery of large yet ecologically important carnivores poses a formidable global challenge. Tiger (Panthera tigris) recovery in India, the world's most populated region, offers a distinct opportunity to evaluate the socio-ecological drivers of megafauna recovery. Tiger occupancy increased by 30% (at 2929 square kilometers per year) over the past two decades, leading to the largest global population occupying similar to 138,200 square kilometers. Tigers persistently occupied human-free, prey-r...
