Globale Landnutzung verändert Treibhausgasemissionen: Neues Berechnungsmodell in Entwicklung

Die Nutzung von Biomasse für Energie und Rohmaterialien ist global auf dem Vormarsch, mit weitreichenden Auswirkungen auf die Ökosysteme. Auf Grund von Landnutzungskonkurrenzen könnte dies allerdings zu erheblichen Emissionen von Treibhausgasen führen. Mit einem neuen Modell, das ForscherInnen an der AAU nun in einem vom Wissenschaftsfonds FWF finanzierten Projekt entwickeln wollen, sollen diese Effekte nun berechnet werden.

The prevalence of mental disorders among older people is greater than previously assumed

Previous studies have largely assumed that the prevalence of mental disorders declines with old age. The results of a new large-scale study with innovative diagnostic methods conducted in six European countries reveal that, considering the previous year retrospectively, approximately one third of the respondents in the age group between 65 and 85 had suffered from a mental disorder, and roughly one quarter were mentally ill at the time of the interviews. The results have now been published in the renowned “British Journal of Psychiatry”.

Andrea Tonello and his former PhD student Alberto Pittolo received the prestigious IET 2016 Premium Award for the Best Paper published in IET Communications over the past two years

The paper “Physical layer security in power line communication networks: an emerging scenario, other than wireless” is a landmark paper that sheds new light on the information theoretic limits for secure communications in power line communication (PLC) channels.

Biomass turnover time in ecosystems is halved by land use

In order to improve our understanding of climate change and to increase the predictability of future dynamics, it is necessary to gain a better understanding of the global carbon cycle. To date, little is known about the average time carbon is stored in biomass, before it passes back into atmosphere or soils (biomass turnover time), and the factors influencing this key parameter also remain largely unknown. Now, a new publication in Nature Geoscience shows that biomass turnover time in vegetation is halved as a result of human influence.
