Immediate shift towards source dynamics: The pioneer species Conyza canadensis in an initial ecosystem

Aqueous tissue extracts of Conyza canadensis inhibit the germination and shoot growth of three native herbs with no autotoxic effects

“…It is a versatile and highly adaptive invader that is found in many parts of the world (Dauer et al, 2007;Zaplata, 2011). It was first recorded in Yantai, Shandong province of China in 1862 (Xie et al, 2001), and is now widely distributed throughout the 28 provinces and listed as one of the most noxious, invasive plants in China (Weber et al, 2008).…”

Impact of dumped sediment structures on hydrological modelling in the artificial Chicken Creek catchment, Germany

“…Plant immigration processes led to the spreading of vegetation. In 2006, vegetation coverage was less than 1.5%, and in 2007, it was already 7% and 13% by 2008 (Mazur et al, 2011;Zaplata et al, 2011). In 2009, the vegetation coverage reached nearly 30%.…”

“…Because some processes, such as subsurface flow or evapotranspiration, cannot be observed directly in the Chicken Creek catchment, hydrological modelling studies were conducted to supplement the measurements (Bormann, 2011;Hofer et al, 2011;Holländer et al, 2009;Hölzel et al, 2011). The results of the monitoring, published in several studies (Gerwin et al, 2010;Mazur et al, 2011;Schaaf et al, 2010;Schneider et al, 2011;Zaplata et al, 2011), provide a sufficient database for a wide range of hydrological model-based research. Hofer et al (2011) simulated the impact of subsurface flow-paths on runoff and showed that the development of a subsurface flow-path network is crucial for hydrological connectivity.…”

Ten years primary succession on a newly created landfill at a lagoon of the Mediterranean Sea (Lake Burullus RAMSAR site)

“…Mesembryanthemum, Sarcocornia, Suaeda, Spergularia and Cakile maritima). Such pioneer species are known to produce high amount of seeds (Davy et al, 2001;Erfanzadeh et al, 2010;Wolters and Bakker, 2002;Zaplata et al, 2011). In the last year (2010) the proportion of the perennial species seemed to be partially stable, while that of the therophytes was still increased.…”
