• Repeatability is the cornerstone of science, and it is particularly important for systematic reviews. However, little is known on how researchers’ choice of database, and search platform influence the repeatability of systematic reviews. Here, we aim to unveil how the computer environment and the location where the search was initiated from influ...

Full-text available
The Asian clam (Corbicula fluminea) is one of the rapidly spreading, very successful aquatic invasive species, which has become established widely in many parts of the world. Its spread is assumed to be by both passive and active dispersal. However, the importance of active pedal movement in dispersal is hardly known. Since there was no direct evid...
Article
We present the results of the first-ever DNA barcoding study of odonates from the Maltese Islands. In total, ten morphologically identified species were collected during a two-week long expedition in 2018. Eighty cytochrome c oxidase subunit I (COI) barcodes were obtained from the collected specimens. Intra- and interspecific distances ranged from...

Full-text available
Stream macroinvertebrates, as non-target organisms, may face with either a single or a complex stressor during a restoration treatment. We quantified the structural, phylogenetic, and functional responses to both single (water retention) and complex (water retention and grazing) stressors and analysed how the ecological quality changes, in order to...

Repeatability is the cornerstone of science and it is particularly important for systematic reviews. However, little is known on how database and search engine choices influence replicability. Here, we present a comparative analysis of time-synchronized searches at different locations in the world, revealing a large variation among the hits obtaine...

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...

Full-text available
Owing to their limited geographical distribution and unique ecological characteristics , Pannonian salt marshes and soda pans are considered among the most vulnerable aquatic habitats in Europe. Despite the unique nature of the soda pans and adjacent wetlands, little is known about their aquatic macroinvertebrate fauna, and there is a shortfall in...
Article
Full-text available
The role of environmental control and spatial structuring may vary depending on dispersal mode within a metacommunity in stream systems. However, as a result of high seasonal variation in environment conditions and phenological features, there might be considerable seasonal changes in the relative importance of structuring factors. The objective of...
Chapter
Due to the untouched and almost pristine conditions of the Drava region, to date 438 species belonging to various aquatic macroinvertebrate animal groups have been recorded from the Drava and its floodplain. Therefore the aquatic fauna of this area is among the richest in Hungary. The most unique species of the Drava is the caddisfly Platyphylax fr...

(The paper is in Hungarian with English abstract, published in Crisicum journal) The Fehér-tó is one of the most important astatic soda pans in the Carpathian basin. The pond is separated by a dam to eastern and western basins, which are different in hydrological regime and extension of macrovegetation. In 2015 physico-chemical parameters were meas...

Partition of beta diversity into components is a modern method that allows inferences about the underlying processes driving metacommunities. Based on two alternative approaches, we examined the patterns of beta diversity components of chironomids in relation to environmental and spatial gradients in three contrasting freshwater ecosystems. Beta di...
Article
Full-text available
Taxonomic and functional patterns of macroinvertebrate communities were investigated to reveal the importance of different habitat units within a marsh system in maintaining its macroinvertebrate diversity. Hydrogeomorphic units based on their functional characteristics were used to distinguish 3 types of aquatic habitats within the marsh system: (...

Detailed new records of 101 aquatic beetle taxa from 179 sites of Rhodes, Crete and Corfu Islands were given. Further species which were only known from these islands based on publication data and database records were also listed. Regarding the eight discussed families, 11, 16 and 18 species were recorded for the first time, and the number of wate...
Article
• Quantifying the relative importance of how local (environmental or niche‐based) and regional (dispersal‐related or spatial) processes regulate the assembly of communities has become one of the main research avenues of community ecology. It has been shown that the degree of isolation of local habitats in the landscape may substantially influence t...
Article
Although the influence of invasive species on the distribution of native species is well-studied, our knowledge on the processes driving the co-occurrence of native gammarid species is limited. We studied the co-occurrence of two common European gammarids, Gammarus fossarum and Gammarus roeselii, along a stream continuum in Mecsek Mountains, SW Hun...

Con­sid­er­ing the on­go­ing loss of aquatic habi­tats, an­thro­pogenic ponds are gain­ing im­por­tance as sub­sti­tute habi­tats. It is there­fore im­por­tant to as­sess their func­tion­ing in com­par­i­son to their nat­ural pre­cur­sors.

Two larvae collected from the River Tisza were recognized to belong to the genus Parasetodes according to the available generic description. The fact that Parasetodes respersellus is the only European/Western Palaearctic representative of the genus enabled us to describe the hitherto unknown larva of this species based on the collected specimens. D...

Although the sex ratio of Odonata at emergence has received much attention, we are still far from understanding the exact causes of its variability and imbalance. In this paper we studied the sex ratios at emergence in natural populations of two Gomphus species based on samples of exuviae taken from two European lowland rivers. We hypothesized a po...

The spatial variability of Chironomidae larvae assemblages was investigated at 6 near-pristine, temperate headwaters in Hungary. Sites were located within a relatively small mountain range but belong to two different catchment areas characterized by highly variable abiotic conditions. We hypothesised there would be differences in taxonomic composit...

The Sajó River was one of the most industrialized and polluted rivers in Hungary and Slovakia. Due to changes in industrial technologies the water quality of the river considerably increased. Unfortunately, our knowledge on the caddisfly fauna of the Sajó River is very limited, thus it was reasonable to collect new distributional data. In 2011 and...

The Nyirkai-Hany wetland reconstruction area in northwestern Hungary is now designated as a Ramsar and a Natura 2000 site. It was created in 2001–2002 by the Fertő-Hanság National Park Directorate to restore a part of the formerly drained large wetland called Hanság and to offer waterbirds a suitable habitat for feeding and breeding. We focused on...

The assemblages of aquatic insects are important members of water ecosystems. Based on former studies among the most important factors structuring the assemblages are numerous abiotic ones, such as the sort and the particle size of the substratum. Most of the sampling protocols, e.g. AQEM, determine microhabitats based on those. Nevertheless, we ha...

In 2006–2007 larval caddisfly assemblages of a semi-natural calcareous stream (Örvényesi Creek) were studied. Characteristic sections can be detected along the whole length of the stream, which passes through diverse types of vegetation, resulting in highly heterogeneous aquatic habitats. Based on an annual survey of different aquatic habitats, our...
