Krondroppsnätets övervakning av luftföroreningar i Norrland : mätningar och modellering : resultat t.o.m. september 2010
Swedish Butterfly Monitoring Scheme, annual report for 2010
This is the first annual report for the Swedish Butterfly Monitoring Scheme, a new national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency. The programme was initiated in 2010, and is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sci
Small-scale climate variability and its ecosystem impacts in the sub-Arctic
Abstract in Undetermined To improve our knowledge of climate change and its impacts on ecosystem services, and to inform local people and governments that need assistance with the development of mitigation and adaptation strategies, climate impacts need to be understood urgently at the smaller scale. On one hand, the microclimate/topoclimate is known to be strongly decoupled from the general macro

Swedish Butterfly Monitoring Scheme, annual report for 2011
This is the second annual report for the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedi

The effect of the temporal resolution of NDVI data on season onset dates and trends across Canadian broadleaf forests
Satellite remote sensing has the potential to contribute to plant phenology monitoring at spatial and temporal scales relevant for regional and global scale studies. Historically, temporal composites of satellite data, ranging from 8 days to 16 days, have been used as a starting point for satellite-derived phenology data sets. In this study we assess how the temporal resolution of such composites
Mapping daily evapotranspiration and dryness index in the East African highlands using MODIS and SEVIRI data
Routine information on regional evapotranspiration (ET) and dryness index is essential for agricultural water management, drought monitoring, and studies of water cycle and climate. However, this information is not currently available for the East Africa highlands. The main purpose of this study is to develop (1) a new methodology that produces spatially gridded daily ET estimates on a (near) real
Ensemble analysis of frost damage on vegetation caused by spring backlashes in a warmer Europe
Tree dehardening and budburst will occur earlier in a warmer climate, and this could lead to an increased risk of frost damage caused by temperature backlashes. By using a spring backlash index and a cold hardiness model, we assessed different aspects of risk for frost damage in Norway spruce forests during the present climate and for one future emission scenario. Uncertainties associated with cli
Impact of human population density on fire frequency at the global scale
Human impact on wildfires, a major earth system component, remains poorly understood. While local studies have found more fires close to settlements and roads, assimilated charcoal records and analyses of regional fire patterns from remote-sensing observations point to a decline in fire frequency with increasing human population. Here, we present a global analysis using three multi-year satellite-
Does conservation on farmland contribute to halting the biodiversity decline?
Biodiversity continues to decline, despite the implementation of international conservation conventions and measures. To counteract biodiversity loss, it is pivotal to know how conservation actions affect biodiversity trends. Focussing on European farmland species, we review what is known about the impact of conservation initiatives on biodiversity. We argue that the effects of conservation are a
Phenology and its role in carbon dioxide exchange processes in northern peatlands
Ecosystem phenology plays an important role in carbon exchange processes and can be derived from continuous records of carbon dioxide (CO2) exchange data. In this study we examined the potential use of phenological indices for characterizing cumulative annual CO2 exchange in four contrasting northern peatland ecosystems. We used the approach of Jonsson and Eklundh (2004) to derive a set of phenolo
Population dynamics of the spruce bark beetle: a long-term study
Bark beetle population dynamics is thought to be primarily driven by bottom-up forces affecting insect performance and host tree resistance. Although there are theoretical predictions and empirical evidences that predation and parasitism may play an important role in driving bark beetle population fluctuations, long-term studies testing the role of both biotic and abiotic controls on population dy
