Intensive human activities have resulted in a critical reduction of grasslands in Croatia, one of the richest Europian countries in terms of biodiversity. Sub-Pannonic steppic grasslands are very rare, only few occur in the continental part of Croatia and most of them are protected as NATURA 2000...

Amorpha fruticosa L. represents one of the most dangerous invasive neophytes spreading quickly in many countries and cities of southeastern Europe where it aggressively penetrates into newly invaded sites and establishes permanently. It prefers moist and periodically flooded terrains, being...

The use of exotic species in reforestations is one of the highly criticized forest policies in the Philippines, mainly due to their perceived negative impacts on biodiversity conservation. To ascertain the influence of exotic plantations on native flora establishments, we inventoried the structure, ...

Aim: Plant invasions often follow initial introduction with a considerable delay. The current non-native flora of a region may hence contain species that are not yet naturalized but may become so in the future, especially if climate change lifts limitations on species spread. In Europe, non-native...

Aim: Modern species invasions result in the global reshuffling of regional floras, but biogeographical biases in floristic exchanges (origin effects) are underexplored. We compared habitat-level invasion patterns in two environmentally similar regions, and ask whether plant exchanges are also...
