Droughts and rainfall in south-eastern Finland since AD 874, inferred from Scots pine ring-widths
Early summer (May-June) precipitation variability was reconstructed for south-eastern Finland using a millennia-long (from 874 to present day) ring-width chronology of Scots pine (Pious sylvestrisExpand

Aquatic food web dynamics on a floodplain in the Okavango delta, Botswana
The study presents the succession of food web compartments during the annual flood of a floodplain of the great inland delta, Okavango, Botswana, and emphasizes how the floodplains serve as keyExpand

Use of modeled photosynthesis and decomposition to describe tree growth at the northern tree line.
Growth of subarctic Scots pine (Pinus sylvestris L.) trees was investigated by a combination of process-based models and dendroecological approaches. Tree ring width indices were stronglyExpand

Growth indices of North European Scots pine record the seasonal North Atlantic Oscillation
A network of 30 ring-width chronologies of Scots pine (Pinus sylvestris L.) from various parts of the boreal forest belt in north Europe were calibrated against seasonal indices of the North AtlanticExpand

Food webs and energy fluxes on a seasonal floodplain: The influence of flood size
The world’s largest inland delta, located on the Okavango River in Botswana, faces major changes in the annual flooding size and duration due to climatic shifts and increased water use. We examinedExpand

Dancing around the pole: holarctic phylogeography of the Arctic fairy shrimp Branchinecta paludosa (Anostraca, Branchiopoda)
The distributional patterns of Arctic species are commonly affected by the recurring Pleistocene glaciations, which contributed to transient or permanent genetic isolation. Here we explore theExpand

Testing dependence between growth and needle litterfall in Scots pine--a case study in northern Finland.
Both drought and fungal disease increase needle litterfall of Scots pine (Pinus sylvestris L.) trees, but most factors causing annual variation in needle litterfall are poorly understood. WeExpand

Summer temperature affects the ratio of radial and height growth of Scots pine in northern Finland
Abstract• Radial and height growth chronologies from 150-year-old and 50-year old Scots pine stands, both located near to the northern timberline in Laanila, Finland (68° 30′ N, 27° 28′ E), wereExpand

Forest harvest effects on mercury in streams and biota in Norwegian boreal catchments
Abstract Forest harvesting practices can potentially increase mercury run-off from catchments. A paired catchment experiment was conducted in a boreal forest in southern Norway, to test effects ofExpand
