Cities and their rising impacts on biodiversity versity. To gain a clearer picture of the situation, an international group of scientists, including Professor Andrew Gonzalez from 鲍鱼直播鈥檚 Biology Department, surveyed over 600 studies on the impacts of urban growth on biodiversity. They published their findings today in Nature Sustainability.

Surprisingly, in any single location, there are typically more earthworms and more earthworm species found in temperate regions than in the tropics, according to a study published this week in Science. Global climate change could lead to significant shifts in earthworm communities worldwide, threatening the many functions they provide.

A new study, published in Science, which focuses on mapping biodiversity change in marine and land ecosystems shows that loss of biodiversity is most prevalent in the tropic, with changes in marine ecosystems outpacing those on land. The research, led by scientists from the University of St Andrews, in collaboration with leading universities across Europe, the USA and Canada, including 鲍鱼直播, aimed at reaching a consensus about variation in biodiversity change.

More than two-thirds of Canada鈥檚 biodiversity is made up of species that occur within the country鈥檚 borders only at the very northern edge of their range. Biologists have long debated how much effort should be dedicated to conserving these 鈥渆dge populations.鈥� One argument in their favour is that they may be especially well suited to lead northward range shifts for their species as the climate warms.

One of the world鈥檚 7,000 languages vanishes every other week, and half 鈥� including scores of indigenous North American languages -- might not survive the 21st century, experts say. To preserve as much linguistic diversity as possible in the face of this threat, 鲍鱼直播 scientists are proposing to borrow a leaf from conservation biology.
