Intense efforts are currently devoted to disentangling the relationships between plant carbon (C) allocation patterns and soil nitrogen (N) availability because of their consequences for growth and more generally for C sequestration. In cold ecosystems, only a few studies have addressed whole-plant C and/or N allocation along natural elevational or topographical gradients. (12)C/(13)C and (14)N...

To update estimates of the prevalence of occupational exposures to carcinogens in Italy, the 85 CAREX agents were re-assessed. The original exposure estimates in the CAREX database were updated, taking into account changes in exposure patterns and in numbers of employees by industrial class. The 21.8 million employees in Italy, 19.4 in industry and services, 2.4 in agriculture, had 4.2 million ...

On 24 October 1950, fourteen people met at the invitation of the abbé Arthur Maheux in the Institut d’Histoire et de Géographie, of the Université Laval in Quebec City to form the Société canadienne d’histoire de la médecine (SCHM). Among them were physicians, historians, and archivists. Dr. Sylvio Leblond (1901-1990), internist and instructor of medical history at Laval, was elected president ...

It is increasingly acknowledged that soil biota may influence interactions among plant species; however, little is known about how to change historical influences of previous land management on soil biota, the so-called 'biotic soil legacy effect'. We used a two-phase plant community-soil feedback approach to study how plant species typical to original (i.e. undisturbed) and degraded fen meadow...
