Climate change fundamentally affecting European birds
Global warming is changing European birds as we know them, a study has found, but it’s not just the increase in temperature that’s to blame.
Researchers have found that garden warblers, for example, are having a quarter fewer chicks, which has huge implications for the species. Chiffchaffs are laying their eggs 12 days earlier. Some birds are decreasing in size, while others, such as redstarts, are getting larger.
The study found that although more than half of trait changes are linked with rising temperatures – and warming is likely the largest factor driving change over the years – other factors such as urbanisation, pollution, habitat loss and more could also affect shifts in characteristics.
European Forests Shift
New research from Northern Arizona University shows Earth’s most northern forests have begun to shift because of warming global temperatures. KNAU’s Melissa Sevigny reports.
The researchers examined four decades of satellite observations of the boreal forests that stretch across Alaska, Canada, and Russia. They eliminated areas that were burned, logged, or otherwise disturbed to focus only on the effects of climate change.
They found that conifers on the northern edges of boreal forests are moving northward. But the southern edges became browner, indicating die-offs.
