Do managed bees drive parasite spread and emergence in wild bees?
Bees have been managed and utilised for honey production for centuries and, more recently, pollination services. Since the mid 20th Century, the use and production of managed bees has intensified with

Every year, in all mountainous regions, people are victims of avalanches. One way to decrease those losses is believed to be informing about danger levels. The paper presents a study on current practices
View ArticleDo healthy Monarchs migrate farther? Tracking natal origins of parasitized...
Long-distance migration can lower parasite prevalence if strenuous journeys remove infected animals from wild populations. We examined wild monarch butterflies (Danaus plexippus) to investigate the

The long-term rise in global temperatures, the dominant cause of which is the anthropogenic emission of greenhouse gases, combined with the effects of a developing El Niño, have resulted in unusual global
View ArticleCharacterizing the GHG emission impacts of carsharing: a case of Vancouver
Carsharing exemplifies a growing trend towards service provision displacing ownership of capital goods. We developed a model to quantify the impact of carsharing on greenhouse gas (GHG) emissions. The
View ArticleCarbon sequestration in managed temperate coniferous forests under climate...
Management of temperate forests has the potential to increase carbon sinks and mitigate climate change. However, those opportunities may be confounded by negative climate change impacts. We therefore
View ArticleHuman behaviour can trigger large carnivore attacks in developed countries
The media and scientific literature are increasingly reporting an escalation of large carnivore attacks on humans in North America and Europe. Although rare compared to human fatalities by other wildlife,
View ArticleSensitivity of global terrestrial ecosystems to climate variability
The identification of properties that contribute to the persistence and resilience of ecosystems despite climate change constitutes a research priority of global relevance. Here the researchers present
View ArticleProductivity of North American grasslands is increased under future climate...
Grassland productivity is regulated by both temperature and the amount and timing of precipitation. Future climate change is therefore expected to influence grassland phenology and growth, with...
