Are the insects which begin their adult life in the coldest months the largest? An accepted paradigm within ecology, Bergmann's rule, says that organisms in the coldest regions of the Earth tend to be larger. Two months ago, Sergio Osorio presented his doctoral thesis at CREAF in which he analyzed this principle to test if seasonality is also related with body size.
Experts at CREAF say that bee populations are on the decline and that pesticides such as neonicotinoids are one of the main causes. It is important to promote organic, sustainable agriculture and move forward on the prohibition of these compounds.
