Das Aufwachsen in einer suchtbelasteten Familie kann für die Kinder langfristige Folgen haben, die auch im Erwachsenenalter noch spürbar sind. Allerdings gibt es auch viele Betroffene, die später ein weitgehend normales Leben führen können. Das Buch setzt sich kritisch mit den internationalen Forschungsergebnissen zu Risiken und Auffälligkeiten der Kinder von Abhängigen auseinander. Es thematisiert insbesondere auch die Chancen und Möglichkeiten für eine erfüllte Lebensgestaltung der Betroffenen.Das Buch geht ausführlich auf die Frage des erhöhten Abhängigkeitsrisikos der Betroffenen im Erwachsenenalter ein. Aufbauend auf diesen Erkenntnissen wird ein Modell der Transmission von Abhängigkeit in Suchtfamilien vorgestellt. In weiteren Kapiteln wird zudem aufgezeigt, wie Hilfeleistende, Eltern und Betroffene mit dem Abhängigkeitsrisiko umgehen sollten und welche Möglichkeiten der Prävention einer Suchtentwicklung existieren.

Native biodiversity decline and non-native species spread are major features of the Anthropocene. Both processes can drive biotic homogenization by reducing trait and phylogenetic differences in species assemblages between regions, thus diminishing the regional distinctiveness of biotas and likely have negative impacts on key ecosystem functions. However, a global assessment of this phenomenon is lacking. Here, using a dataset of >200,000 plant species, we demonstrate widespread and temporal decreases in species and phylogenetic turnover across grain sizes and spatial extents. The extent of homogenization within major biomes is pronounced and is overwhelmingly explained by non-native species naturalizations. Asia and North America are major sources of non-native species; however, the species they export tend to be phylogenetically close to recipient floras. Australia, the Pacific and Europe, in contrast, contribute fewer species to the global pool of non-natives, but represent a disproportionate amount of phylogenetic diversity. The timeline of most naturalisations coincides with widespread human migration within the last ~500 years, and demonstrates the profound influence humans exert on regional biotas beyond changes in species richness. ; We thank Texas A&M University-Corpus Christi and the Harvard University Herbaria for logistic and financial support.

Declines in insect pollinators across Europe have raised concerns about the supply of pollination services to agriculture. Simultaneously, EU agricultural and biofuel policies have encouraged substantial growth in the cultivated area of insect pollinated crops across the continent. Using data from 41 European countries, this study demonstrates that the recommended number of honeybees required to provide crop pollination across Europe has risen 4.9 times as fast as honeybee stocks between 2005 and 2010. Consequently, honeybee stocks were insufficient to supply >90% of demands in 22 countries studied. These findings raise concerns about the capacity of many countries to cope with major losses of wild pollinators and highlight numerous critical gaps in current understanding of pollination service supplies and demands, pointing to a pressing need for further research into this issue.

Analysing temporal patterns in plant communities is extremely important to quantify the extent and the consequences of ecological changes, especially considering the current biodiversity crisis. Long-term data collected through the regular sampling of permanent plots represent the most accurate resource to study ecological succession, analyse the stability of a community over time and understand the mechanisms driving vegetation change. We hereby present the LOng-Term Vegetation Sampling (LOTVS) initiative, a global collection of vegetation time-series derived from the regular monitoring of plant species in permanent plots. With 79 data sets from five continents and 7,789 vegetation time-series monitored for at least 6 years and mostly on an annual basis, LOTVS possibly represents the largest collection of temporally fine-grained vegetation time-series derived from permanent plots and made accessible to the research community. As such, it has an outstanding potential to support innovative research in the fields of vegetation science, plant ecology and temporal ecology. ; The authors acknowledge institutional support as follows.
