[PDF][PDF] Preserving species populations in the boreal zone in a changing climate: contrasting trends of bird species groups in a protected area network

R Virkkala, A Rajasärkkä - Nature conservation, 2012 - natureconservation.pensoft.net
A protected area network should ensure the maintenance of biodiversity. Because of climate
change, species ranges are expected to move polewards, causing further demand for the …

Significance of protected area network in preserving biodiversity in a changing northern European climate

R Virkkala, RK Heikkinen, S Kuusela, N Leikola… - Handbook of climate …, 2019 - Springer
Climate change is a major threat to biodiversity, causing species to move to new climatically
suitable areas, and thus increasing the extinction probability of species inhabiting …

Birds in boreal protected areas shift northwards in the warming climate but show different rates of population decline

R Virkkala, A Rajasärkkä, RK Heikkinen… - Biological …, 2018 - Elsevier
Climate change has the potential to have wholesale impacts on species populations, driving
them polewards and upwards, and even affecting populations occurring within protected …

Uneven regional distribution of protected areas in Finland: consequences for boreal forest bird populations

R Virkkala, A Rajasärkkä - Biological Conservation, 2007 - Elsevier
The significance of reserves in maintaining forest bird species of conservation concern (N=
36) was studied by large-scale quantitative line transect bird censuses in Finland, which …

Does the protected area network preserve bird species of conservation concern in a rapidly changing climate?

R Virkkala, RK Heikkinen, S Fronzek, H Kujala… - Biodiversity and …, 2013 - Springer
Species ranges are expected to move polewards following the changing climate, which
poses novel challenges to the protected area network, particularly at northern latitudes. Here …

[HTML][HTML] Clear-cuts and warming summers caused forest bird populations to decline in a southern boreal area

R Virkkala, AM Määttänen, RK Heikkinen - Forest Ecology and …, 2023 - Elsevier
Land use and climate change are the main drivers of biodiversity change. However, their
relative roles in the decline of biodiversity are still insufficiently known. Climate change is …

Can protected areas buffer short-term population changes of resident bird species in a period of intensified forest harvesting?

R Virkkala, A Lehikoinen, A Rajasärkkä - Biological Conservation, 2020 - Elsevier
Protected areas (PAs) should maintain populations of focal species, but their ability to
achieve this target is affected both by land use outside PAs and by climate warming. To …

Northward density shift of bird species in boreal protected areas due to climate change

R Virkkala, A Rajasärkkä - Boreal Environment Research, 2011 - search.proquest.com
Species ranges are expected to move latitudinally poleward because of the warming
climate. We asked whether northward patterns are observable also in population densities …

Climate change affects populations of northern birds in boreal protected areas

R Virkkala, A Rajasärkkä - Biology Letters, 2011 - royalsocietypublishing.org
Human land-use effects on species populations are minimized in protected areas and
population changes can thus be more directly linked with changes in climate. In this study …

Population trends of forest birds in a Finnish Lapland landscape of large habitat blocks: consequences of stochastic environmental variation or regional habitat …

R Virkkala - Biological Conservation, 1991 - Elsevier
Birds were counted in Northern Finnish Lapland in an area situated 200 km north of the
Arctic Circle in virgin forests in the 1940–1950s, and both in virgin and managed forests in …
