ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Identifying knowledge gaps about context dependency in freshwater species invasions
The abiotic template of freshwater ecosystems is being altered by human activity on a global scale, often promoting the establishment of new invasive taxa and increasing the likelihood of facilitation between invaders. These positive interactions represent a substantive threat to freshwater ecosystems by promoting the establishment and persistence of ...
