Drought alters recovery of Rocky Mountain forests after fire
Latest Science News -- ScienceDaily - Hace 11 horas
A changing climate is altering the ability of Rocky Mountain forests to recover from wildfire, according to a new study. When warm, dry conditions lead to drought in the years following fires, it impedes the growth and establishment of vulnerable new post-fire seedlings. The study also shows that forest recovery has been negatively affected by increased distances between burned areas and the sources of seeds that typically replace trees lost to fire.

Old tourist photos show seabird's rise over the last century
Latest Science News -- ScienceDaily - Hace 12 horas
Researchers have used tourist photos to reconstruct the rise and fall of common guillemots, one of the largest auk species. Those data show that the guillemots suffered early in the 20th century, but their numbers have now risen to a historically high level. They also demonstrate the power of amateur photos and other unconventional sources of evidence to help fill gaps in the scientific record.
