ScienceDaily: Scientists have found that strains of the wheat pathogen causing severe yellow rust epidemics in Europe have their origin in the centre of diversity in the Himalayan region. This disease can have a great impact on wheat production in Europe, including organic crop production in Denmark. Wheat is the most widely cultivated food crop in the world. However, the global production of wheat is under constant threat from devastating fungal diseases. The ever more frequent and severe large-scale epidemics...

Massive Bird Invasions Linked to Climate Shifts

Nature World: Massive bird invasions taking place across the United States and Canada, a phenomenon that has long puzzled scientists and birdwatchers alike, is reportedly linked to climate shifts, new research indicates. Over the years, vast numbers of birds from Canada's boreal forests have migrated hundreds-of-thousands of miles south from their usual winter range. While previous studies have blamed these so-called irruptions on food shortages, it seems that climate also plays a role. Specifically, persistent...

Massive southern invasions by northern birds linked climate shifts

ScienceDaily: With puzzling variability, vast numbers of birds from Canada's boreal forests migrate hundreds or thousands of miles south from their usual winter range. These so-called irruptions were first noticed by birdwatchers decades ago, but the driving factors have never been fully explained. Now scientists have pinpointed the climate pattern that likely sets the stage for irruptions -- a discovery that could make it possible to predict the events more than a year in advance. The researchers found that...
