Assessing the Invasion Risk of <i>Humulus scandens</i> Using Ensemble Species Distribution Modeling and Habitat Connectivity Analysis by Mariana Mihaela Urziceanu, Alina Georgiana Cîșlariu, Eugenia Nagodă, Alma Lioara Nicolin, Dragoș Ștefan Măntoiu, Paulina Anastasiu

“…<i>H. scandens</i> is highly influenced by milder climates and areas with constant flooding events, thus we found that the Tisa basin and its tributaries can be under a high invasion risk, spreading through the entire catchment, in Central, Western, and Northern Romania, towards the Eastern Carpathians. The Danube acted as a dispersion corridor for major river systems in southern Romania, but the dispersion capability of the species dropped in steppe areas with higher aridity and limited water course network. …”
