Freshwater ecosystems represent an unparalleled diversity of habitats and species, but the actual distribution many species remains obscured or incomplete. The aim survey was to contribute knowledge on fauna lesser-known areas fill gaps in maps species. dataset is based a one-year-long study surveying 60 locations from different drying river networks that ecoregions Central Europe: Balcanic (Croatia, 15 sites), Continental (Czechia, 20 sites) Pannonian (Hungary, 25 sites). Multihabitat...
ABSTRACT Aim Understanding the joint influence of natural disturbance regime, connectivity and biogeography on seasonal variation community structure. Location Drying river networks (DRN) in Europe. Time Period Present. Major Taxa Studied Aquatic macroinvertebrates. Methods We analyse taxonomic trait structure 638 macroinvertebrate communities sampled across 125 reaches with perennial intermittent streamflow, surveyed six DRNs Europe, up to times over 1 year. Results Richness diversity...
ABSTRACT Spatial connectivity varies temporally due to fragmentation caused by drying and may potentially define the diversity composition of communities. We studied spatiotemporal patterns in three river networks (DRNs) Croatia, Czechia Hungary, with varying patterns, focusing on roles local environmental variables regional influences. aimed assess how variation (STcon) influenced metacommunity structure dynamics, contributing our understanding rapidly changing aquatic ecosystems under...
Abstract Intermittent rivers and ephemeral streams are the world's dominant type of river ecosystem becoming more common because global change. However, inclusion intermittent in water policies management plans remains largely limited monitoring schemes tools designed for perennial rivers. In present article, we discuss how smartphone applications used by citizen scientists can quantify extent occurrence streams. We also introduce a new app, DRYRivERS, specifically to monitor After year use,...
River networks are among Earth’s most threatened hot-spots of biodiversity and provide key ecosystem services (e.g., supply drinking water food, climate regulation) essential to sustaining human well-being. Climate change increased use causing more rivers streams dry, with devastating impacts on services. Currently, than a half the global river consist drying channels, these expanding dramatically. However, (DRNs) have received little attention from scientists policy makers, public is...
Abstract Expertise in biodiversity research (taxonomy, faunistics, conservation with taxonomic background) appears to decline worldwide. While the “taxonomic impediment” is discussed extensively literature, much fewer papers focus on identification crisis, i.e., decreasing number of experts who can identify species, and species-based research. As a test case explore gravity we chose Hungary, Central European country strong history comprehensive expertise output. We set out answer two main...
We present the results of first-ever DNA barcoding study odonates from Maltese Islands. In total, 10 morphologically identified species were collected during a two-week long expedition in 2018. Eighty cytochrome c oxidase subunit I (COI) barcodes obtained specimens. Intra- and interspecific distances ranged 0.00% to 2.24% 0.48% 17.62%, respectively. Successful identification based on ascribing single morphological Barcode Index Number (BIN) was achieved for eight (80%). case two species,...
Climate change is putting increasing pressure on flowing waters. Drastic water level fluctuations in rivers or drying up of small and medium-sized streams all contribute to the biodiversity crisis threatening freshwater ecosystems. Benthic diatoms are important elements biofilm streams. However, knowledge relationship between benthic flow intermittence incomplete, especially regions recently impacted by recurrent drying. Thus, we investigated diatom flora intermittent, hilly warm temperate...
The river Danube is the backbone of ‘southern invasion corridor’, one most important passages for spread Ponto-Caspian invaders in Europe. However, not all these species used passive or active upstream movement main channel to reach upper sections and tributaries, some found detours. Mass occurrences peracarid, Pontogammarus robustoides (Sars, 1894) were recorded at 17 sites along entire Hungarian section River Maros, first time Tisza catchment also Hungary. Those populations are ca. 707 km...
In case of dryings, the hyporheic zone is one most important refugia for stream macroinvertebrate communities, including few Odonata species living in these habitats, such as Cordulegaster species. There no information on desiccation resistance strategies and methods any members genus, heros . We hypothesised that larvae use burrowing behaviour to survive droughts. this study, beyond recording survival rates larvae, we tested effects sediment particle size body a 3‐week‐long simulated...
Abstract The Asian clam ( Corbicula fluminea ) is one of the rapidly spreading, very successful aquatic invasive species, which has become established widely in many parts world. Its spread assumed to be by both passive and active dispersal. However, importance pedal movement dispersal hardly known. Since there was no direct evidence this phenomenon, field observations were combined with laboratory experiments find out if clams move upstream actively, how affected quality substrate, density...
True flies comprise approximately one-tenth of all animal species on Earth, yet despite their prevalence and ecological significance in freshwater ecosystems, members the insect order Diptera are frequently neglected stream studies. This absence or inconsistency regarding literature taxonomic lists may leave readers with a sense discrepancy. To illustrate this underrepresentation quantitative investigations, we conducted targeted literature-based meta-analysis, assessing average level...
Abstract Understanding the joint influence of natural disturbance, spatial connectivity and biogeography on biodiversity is essential to forecast its responses climate change. Macroinvertebrate communities in drying river networks constitute an ideal study system understand interplay these ecological processes. We analyze taxonomic functional structure macroinvertebrate sampled across 126 reaches with perennial intermittent streamflow, surveyed six (DRN) Europe, times over one year. Drying...
Chironomidae, with over 7,300 described species, are amongst the most diverse and abundant insect families in freshwater ecosystems worldwide. Chironomids known for their widespread distribution from various water types. The level of documentation chironomid fauna varies considerably European countries, more comprehensive knowledge Western Europe compared to other regions. Despite recent extensive sampling effort increasing number available data, Central countries still remains poorly known.
In 2018 and 2019, quantitative aquatic macroinvertebrate samplings were carried out in the river network of Bükkösdi-víz (Mecsek Mountain). The identification 325,865 specimens originated from 40 sampling sites resulted occurrences 125 different species belonging to 12 higher taxa (Gastropoda – 9, Bivalvia 1, Hirudinea 4, Malacostraca 6, Ephemeroptera 16, Odonata 12, Plecoptera 3, Heteroptera 19, Coleoptera 23, Megaloptera Neuroptera Trichoptera 28), including 8 protected (Bivalvia: Unio...
