Impact of climate change on the population dynamics of Ips typographus in southern Sweden

Mass-propagation of the spruce bark beetle, Ips typographus, following windfalls and drought is a serious threat to mature spruce forests. Climate change will affect the population dynamics of I. typographus directly as the swarming activity and development rate are mainly controlled by temperature, and indirectly via changes in availability of brood trees. Today, I. typographus is in general univ

Medicine self-poisoning and the sources of the drugs in Lund, Sweden

The purpose of this study was to investigate the prevalence of toxic agents in attempted and completed suicides. The purpose was also to explore the sources of the drugs taken by suicide attempters. Verbal information on drug intake was collected from 280 suicide attempters during 1987-1990 in the Lund-Orup catchment area. Information on the sources of the drugs was collected from 143 of these att

Unemployment and alcohol-related health in Sweden

A large number of studies have explored the relations between unemployment and alcohol-related health, but so far there is no consensus among the results. This paper contributes to the literature by exploring how unemployment is related to overall alcohol consumption as well as to the rates of alcohol poisoning, alcohol addiction and alcohol-related liver disease. A fixed effects model is used on

A multi-scale analysis of biofuel-related land acquisitions in Tanzania : with focus on Sweden as an investor

Spurred on by pressure to find sustainable energy production alternatives to fossil fuels, many industries have been acquiring land in order to plant crops for biofuel production. In Tanzania, biofuel development is in an early stage, and over the last decade, several foreign actors have tried to start up biofuel projects in the country (without success). Land acquisitions are seen by many as a fo

Passerines in Swedish Lapland generally did not advance timing of breeding over the last 30 years

Popular science summary: Climate change, and its effect on nature, is presently a hot research topic. Many studies have focused on the effect of recent climate change on breeding and spring migration in birds. Several bird populations have been shown to advance migration or breeding. It has been suggested that if they do not do this they might miss optimal breeding conditions such as peak food av

Hydrogeological investigation for the PEGASUS project, southern Skåne, Sweden

SLU (Sveriges Lantbruksuniversitet) har ett pågående projekt i ett område i södra Skåne sedan 1989 där de studerar hur bekämpningsmedel i åar korrelerar med vad som används på åkrarna. Ett nytt projekt, initierat av SGI (Statens Geotekniska Institut), kallat PEGASUS (PEsticide occurrence in Groundwater, A Study for sustainable Use in Skåne) har påbörjat en undersökning i samma område för att stude
