Below is a press release about the Methods paper ‘Attributing changes in the distribution of species abundance to weather variables using the example of British breeding birds‘ taken from the University of St Andrews.
Britain’s smallest bird species, the goldcrest, is being hit hard by cold winters, new analysis methods developed by researchers at the University of St Andrews have revealed.
The data analysis techniques, published today in Methods in Ecology and Evolution, take a longer term view over multiple locations and for a period of several years, compared to previous studies.
They showed that the cold temperatures strongly affected breeding numbers of the goldcrest, while in contrast, the song thrush was not affected by the cold, but benefited from wet and mild summers. Continue reading
