Predatory fish species play a key role in aquatic ecosystems by exerting top‐down control
on the food web. Also, their intra‐guild trophic interactions (ie competition) are crucial for the …

Invasive fish species impact aquatic ecosystems and modify native communities, often
leading to a decline in local species. These ecological impacts include the transmission of …

Due to the increasing globalisation and ongoing introduction of alien species specifically
regarding European freshwater ecosystems, native and already present alien species will …

Invaders affect native species across multiple trophic levels, influencing the structure and
stability of freshwater communities. Based on the 'trophic position hypothesis', invaders at …

Interactions occurring between species in multiple invaded freshwater ecosystems are often
difficult to observe and study. Studies on invasive alien species typically focus on single …

Freshwater ecosystems are negatively impacted by various pollutants, from agricultural,
