Small things can have a major effect on the prevention of biodiversity loss
The population growth of an endangered butterfly species is greatest in habitats with microclimatic variability, demonstrates a study carried out collaboratively by the Faculty of Biological and Environmental Sciences and the Helsinki Institute of Life Science of the University of…
Light pollution at night affects the calls of migratory birds
When investigators in the UK recorded the calls of migratory birds called thrushes at night, they found that call rates were up to five times higher over the brightest urban areas compared with darker villages. The findings, which are published…
