How will animals dodge cities and roads as they outrun climate change?
When climate change forces animals to trek to cooler regions, these species will run into obstacles such as roads, cities, and farms. Now scientists at the University of Washington have mapped the most common paths that animals will likely take as they search for more hospitable habitat while avoiding highly-developed land.
This won’t be the […] Read More »
Vine infestations reduce forests' carbon storage
Vines that choke tropical trees have cut some forests’ carbon storage by more than half, according to a study in Biology Letters.
Lianas are parasitic woody vines that prey on trees. In infested forests, trees don’t grow as big and are more likely to die. As tropical forests become fragmented, lianas have flourished and can […] Read More »
Mid-sized groups outperform small and big teams at forest conservation
Protecting the environment demands teamwork. But what group size is the most effective? According to a study in China, mid-sized groups of people are the most successful at conserving forests.
The study took place in China’s Wolong Nature Reserve, which houses one-tenth of the world’s wild giant pandas. As part of a conservation program, more […] Read More »
Grizzlies rely on wildlife corridors to get around
Many grizzly and black bears are using wildlife crossings in a Canadian national park, researchers report. The animals probably rely on the corridors to avoid busy roads and seek out food.
The effectiveness of wildlife corridors “remains surprisingly unknown,” the study authors write in Conservation Biology. The crossings are intended to help animals navigate fragmented […] Read More »
When it comes to carbon emissions, large cities aren't more efficient
“Are larger cities more energy and emissions efficient than smaller ones?” asks a group of researchers in a new PLOS ONE study. That pattern would make sense; after all, big cities often enjoy economies of scale. But after analyzing hundreds of US urban areas, the team concluded that carbon dioxide emissions per person don’t drop […] Read More »
China’s coastal provinces outsource emissions to inland regions
China’s wealthy coastal cities are outsourcing their carbon dioxide emissions to less developed inland regions, researchers say.
Rich countries often import products associated with high CO2 emissions from poor countries. The study authors wanted to find out of this trend applied to regions within a country as well. So they studied trade patterns for 57 […] Read More »
