Warmer climate threatening to northern birds

[font size=4]2016-12-06—Will northern birds such as the Siberian jay and the red-flanked bluetail be gone in 50 years? There is a huge risk since a deteriorating climate for breeding is imminent. Another six species are also under threat and will require particular conservation actions in order to survive, according to Anouschka Hof, former researcher at Umeå University, who has developed a species analysis method[/font]

In collaboration with American researchers, the Umeå-based research team has studied 180 species that currently breed in subarctic and arctic regions by analysing and assessing their vulnerability to new climates as well as their lifespan. This has been conducted by studying how they live today; in what types of environments and in what climates. The information has then been applied to models of future climate.
“By carrying out this type of analysis, we have been able to predict what species are most at risk and why,” she says.
Diversity in nature is under threat as global temperatures increase. Most researchers agree on this, but few studies show the extent of the effects. Most assessments only take into consideration how species are affected by changes in their local environment, without regard to species’ sensitivity to global climate changes. The likelihood of species or populations dwindling or disappearing due to climate change is also affected by the general vulnerability of species and their capacity to survive under new conditions. The interplay between species and other biotic factors has also been overlooked but is receiving increased attention as of late.
The methods used by researchers have identified the species that are particularly in need of surveillance and preservation efforts to survive. For instance, it has been shown that the species already have limited geographic distribution, specific habitat requirements and a low reproduction rate. Furthermore, the methods show that six of the species studied – the great snipe, the rough-legged buzzard, the red-throated pipit, the common swift, the horned lark and the bar-tailed godwit – are already red-listed and will require conservation attention to survive in a warming climate.
