The ADnet Bayesian belief network for alder decline: Integrating empirical data...
Gomes Marques, Inês; Vieites-Blanco, Cristina; Rodríguez-González, Patricia M.; Segurado, Pedro; Marques, Marlene; Barrento, Maria J.The globalization in plant material trading has caused the emergence of invasive pests in many ecosystems, such as the alder pathogen Phytophthora ×alni in European riparian forests. Due to the ecological importance of alder to the functioning of rivers and the increasing incidence of P. ×alni-induced alder decline, effective and accessible decision tools are required to help managers and stakeholders control t...
Dimensions of invasiveness: Links between local abundance, geographic range siz...
Fristoe, Trevor S; Chytrý, Milan; Dawson, Wayne; Essl, Franz; Heleno, Ruben; Kreft, Holger; Maurel, Noëlie; Pergl, Jan; Pyšek, Petr; Seebens, HannoUnderstanding drivers of success for alien species can inform on potential future invasions. Recent conceptual advances highlight that species may achieve invasiveness via performance along at least three distinct dimensions: 1) local abundance, 2) geographic range size, and 3) habitat breadth in naturalized distributions. Associations among these dimensions and the factors that determine success in each have y...
Fine‐grain beta diversity of Palaearctic grassland vegetation
Dembicz, Iwona; Dengler, Jürgen; Steinbauer, Manuel J.; Matthews, Thomas J.; Bartha, Sándor; Burrascano, Sabina; Chiarucci, AlessandroQUESTIONS: Which environmental factors influence fine-grain beta diversity of vegetation and do they vary among taxonomic groups? LOCATION: Palaearctic biogeographic realm. METHODS: We extracted 4,654 nested-plot series with at least four different grain sizes between 0.0001 m² and 1,024 m² from the GrassPlot database, covering a wide range of different grassland and other open habitat types. We derived extensi...
Species–area relationships in continuous vegetation : Evidence from Palaearctic...
Dengler, Jürgen; Matthews, Thomas J.; Steinbauer, Manuel J.; Wolfrum, Sebastian; Boch, Steffen; Chiarucci, Alessandro; Conradi, Timo; Dembicz, IwonaAIM: Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas, power laws best represent SARs. Yet, it remains unclear whether SARs follow other shapes at finer spatial grains in continuous vegetation. We asked which function describes SARs best at small grains and explored how sampling methodology or the environment influence SAR shape. L...
