Swiss study shows widespread effect of air pollution
FRISCO — Scientists in Switzerland say they’ve measured a startling decline in plant diversity linked with high human atmospheric nitrogen emissions. Their study, published in the journal Royal Society Open Science, shows the loss in traditionally measured plant species richness at 5 percent, while the loss in phylogenetic plant diversity due to human-induced nitrogen deposition is 19 percent.

FRISCO — Swiss researchers taking a close look at the effect of global warming say that plants, birds and butterflies sprinted uphill by anywhere from eight to 42 meters between 2003 and 2010 — a significant shift in a very short time, according to the study published
Swiss plants, butterflies and birds have moved 8 to 42 meters uphill between 2003 and 2010, as scientists from the University of Basel write in the online journal Plos One. Other research has shown that, in general, European bird and butterfly communities have moved on average 37 and 114 kilometers to the north, respectively. Continue reading

Conservationists call for restrictions on winter recreation in core habitat areas

SUMMIT COUNTY — In research that might of interest to Summit County leaders as they mull over recreation and development plans, Swiss scientists say they have linked burgeoning winter recreation activities in the Alps with a severe decline of wood grouse populations.
The study, published in the journal IBIS, shows how the growth of human recreation may be a key factor in the rapidly declining population of these iconic alpine birds.
The wood grouse, sometimes called the Capercaillie (Tetrao urogallus), is the largest member of the grouse family and is renowned for its mating display. It is most commonly found in the alpine regions of Germany and Switzerland.
“Alpine habitats across Europe remained relatively undisturbed until the beginning of the last century, but today human outdoor recreation areas coincide with the winter habitats of many shy and endangered species,” said lead author Dominik Thiel, of the Swiss Ornithological Institute. “The Western Capercaillie has suffered rapid population declines during recent decades. However, little is known about their susceptibility to human recreation activities.” Continue reading
