The recovery of European freshwater biodiversity has come to a halt
Haase, Peter; Bowler, Diana E.; Baker, Nathan J.; Bonada, Núria; Domisch, Sami; Garcia Marquez, Jaime R.; Heino, Jani; Hering, Daniel; Jähnig, Sonja C.Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss1. Mitigation measures, including wastewater treatment and hydromorphological restoration, have aimed to improve environmental quality and foster the recovery of freshwater biodiversity2. Here, using 1,816 time series of freshwater invertebrate communities collected across 22 European coun...
Invasion impacts and dynamics of a European-wide introduced species
Haubrock, Phillip J.; Ahmed, Danish A.; Cuthbert, Ross N.; Stubbington, Rachel; Domisch, Sami; Marquez, Jaime R. G.; Beidas, Ayah; Amatulli, GiuseppeGlobalization has led to the introduction of thousands of alien species worldwide. With growing impacts by invasive species, understanding the invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, invasion dynamics have been assumed to follow an "invasion curve" (S-shaped curve of available area invaded over time), but this dynamic has lacked empiric...
Longitudinal river zonation in the tropics: examples of fish and caddisflies fr...
Englmaier, Gernot K.; Hayes, Daniel S.; Meulenbroek, Paul; Terefe, Yonas; Lakew, Aschalew; Tesfaye, Genanaw; Waidbacher, Herwig; Malicky, HansSpecific concepts of fluvial ecology are well studied in riverine ecosystems of the temperate zone but poorly investigated in the Afrotropical region. Hence, we examined the longitudinal zonation of fish and adult caddisfly (Trichoptera) assemblages in the endorheic Awash River (1,250 km in length), Ethiopia. We expected that species assemblages are structured along environmental gradients, reflecting the patte...
