Northward density shift of bird species in boreal protected areas due to climate change / Raimo Virkkala, Ari Rajasärkkä.
Title: | Northward density shift of bird species in boreal protected areas due to climate change / Raimo Virkkala, Ari Rajasärkkä. |
Author(s): | Virkkala, Raimo. Rajasärkkä, Ari. |
Date: | 2011. |
In: | Boreal Environment Research. (2011.), Vol. 16(suppl.B) (2011) |
Abstract: | Investigates whether northward movement of avian species ranges are observable in population densities of land birds in Finnish protected areas, such that temporal population changes would be most pronounced near species range boundaries. Compares population changes of northern species, southern species and species distributed over whole country from 1981-1999 to 2000-2009 in 96 protected areas. Northern species showed greatest decrease in southern Finnish protected areas, and southern species increased most in northern Finnish protected areas. |
