Abstract Climate change has influenced a range of species across the globe. Yet, to state a noted decline in the abundance of a given species as a consequence of a specific environmental change, for instance, spatially explicit long-term data are a p

We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their

Finnish populations of the capercaillie Tetrao urogallus, black grouse Lyrurus tetrix and hazel grouse Tetrastes bonasia have been fluctuating in synchronous cycles. Mechanisms behind these fluctuations are not well known. Parasites may regulate thei

Annual, nationwide monitoring of the grouse (hunted tetraonid birds) began in Finland at the beginning of the 1960s followed by systematic counts of mammal snow tracks in the late 1980s. The wildlife triangle scheme, started in 1989, gathers game mon

Spatial synchrony between populations emerges from endogenous and exogenous processes, such as intra- and interspecific interactions and abiotic factors. Understanding factors contributing to synchronous population dynamics help to better understand

Niche conservatism is the tendency of related species to retain ancestral tolerances after geographic separation. We used Ecological Niche Modelling and Principal Components Analysis of bioclimatic and habitat variables to describe the extent of the
