Fitness to Drive and Cognition

Medication and fitness to drive.

PURPOSE The aim of this study is to analyze the consumption patterns of medicaments among motor vehicle drivers who attend 'Medical Driving Test Centres' and the relation between habitual consumption of medicaments and fitness to drive. METHODS The study was carried out on 8043 drivers who attended 25 Medical Driving Test Centres. RESULTS 24.7% of drivers chronically consume medicaments whi...

Biological pollution in the Mediterranean Sea: invasive versus introduced macrophytes.

The authors have listed 85 species of macrophytes that have probably been introduced to the Mediterranean. Among them, nine species can be considered as invasive, i.e., playing a conspicuous role in the recipient ecosystems, taking the place of keystone species and/or being economically harmful: Acrothamnion preissii, Asparagopsis armata, Lophocladia lallemandii, Womersleyella setacea (Rhodophy...

Does seed mass drive the differences in relative growth rate between growth forms?

The idea that herbaceous plants have higher relative growth rates (RGRs) compared with woody plants is fundamental to many of the most influential theories in plant ecology. This difference in growth rate is thought to reflect systematic variation in physiology, allocation and leaf construction. Previous studies documenting this effect have, however, ignored differences in seed mass. As woody s...
