“…Mysid shrimps, including species such as Hemimysis anomala, Limnomysis benedeni, Katamysis warpachowskyi, and Paramysis lacustris, have become prominent Ponto-Caspian invaders. These species have successfully established in Europe (Audzijonyte et al, 2008(Audzijonyte et al, , 2009Borza et al, 2019;Wittmann, 2008), while H. anomala also invaded the North American Great Lakes (Audzijonyte et al, 2008). Traits such as wide environmental tolerance, omnivory, high annual number of generations, and related ability to get established quickly in new habitats likely contributed to their invasive success (Borza, 2014;Borza et al, 2017).…”

Understanding the diet preferences and food selection of invasive species is crucial to better predict their impact on community structure and ecosystem functioning. Limnomysis benedeni, a Ponto‐Caspian invasive mysid shrimp, is one of the most successful invaders in numerous European river and lake ecosystems. While existing studies suggest potentially strong trophic impact due to high predation pressure on native plankton communities, little is known of its food selectivity between phyto‐ and zooplankton, under different food concentrations. Here, we therefore investigated the feeding selectivity of L. benedeni on two commonly occurring prey organisms in freshwaters, the small rotifer zooplankton Brachionus calyciflorus together with the microphytoplankton Cryptomonas sp. present in increasing densities. Our results demonstrated a clear shift in food selection, with L. benedeni switching from B. calyciflorus to Cryptomonas sp. already when the two prey species were provided in equal biomasses. Different functional responses were observed for the two food types, indicating somewhat different foraging mechanisms for each food type. These findings provide experimental evidence on the feeding flexibility of invasive mysid shrimps and potential implications for trophic interactions in invaded ecosystems.

“…The majority of the invaders are lithophilous peracarid crustaceans which followed a similar pattern during their range expansion; all species reached the upper parts of the river by jump dispersal and colonized the intermediate section by downstream drift (Borza et al, 2015(Borza et al, , 2017. However, in the case of the latest colonist À the psammo-pelophilous Paramysis lacustris (Czerniavski, 1882) À the establishment in the Middle Danube (Borza et al, 2019) was preceded by the appearance in the River Tisza (Borza and Boda 2013).…”

The river Danube is the backbone of the ‘southern invasion corridor’, one of the most important passages for the spread of Ponto-Caspian invaders in Europe. However, not all of these species used the passive or active upstream movement in the main channel to reach the upper sections and tributaries, some found detours. Mass occurrences of the Ponto-Caspian peracarid, Pontogammarus robustoides (Sars, 1894) were recorded at 17 sites along the entire Hungarian section of the River Maros, for the first time in the River Tisza catchment and also in Hungary. Those populations are found ca. 707 km upstream from the closest known and confirmed locality in the lower Danube section. We confirmed their identity by DNA barcoding and showed that all individuals fit in with the lower Danube population, thus identifying the source of this introduction. The most likely vector allowing the jump dispersal of the species is fish stocking in the Romanian section of the River Maros, which − combined with downstream drift to the Serbian Danube section and the relatively busy ship traffic between Belgrade and Vienna − might provide the opportunity to bypass the dispersal barrier represented by the unregulated Middle Danube and open the way towards Western Europe.
