The introduction and spread of alien fish species pose a major threat to native communities and ecosystem functioning in freshwaters. Black bullhead is one of the most successful invaders in European waters with several detrimental effects on native biota and ecosystems. In this study, we used stable isotope analysis to compare the body size and se...

Scales of the ray finned fishes can be used for multiple purposes. Beside others by their specific structure and elemental composition they are usable for age determination and food-web researches. Additionally, just their presence, absence, shape, location, or numbers could provide a reliable taxonomic information. The fish scales show remarkable...

It has long been recognized that presence-absence, localisation, size, number and shape of fish scales can be important taxonomic features. Although there are some notes on the relationship between scale morphology and ecological needs, in the absence of a sufficiently large and detailed database, the morphological variability of fish scales and th...

Our dataset recently consists of 2954 scale photos characterising 193 freshwater fish species. Beside the photos, our database includes the exact taxonomic classification of the studied species, theis average body fineness ratio (SL/H), and the relative scale size, as well as the ecological characteristic of each species. The sampled species have d...

Pikeperch (Sander lucioperca Linnaeus, 1758) is a wide-ranged percid predator fish charac-terised by a great ecological value in the Eurasian freshwater and brackish ecosystems. It is also one of the most famous fish species of Lake Balaton (Hun-gary), where a unique (genetically separated) pike-perch stock lives. However, until now, no detailed in...

Distance-based morphometry is still widely used in ichthyology. Beside others, this methodology is often used to characterise species or to compare intraspecific group (i.e., population level) differences. However, scarce information is available about: a) which are the most widely used variables for these purposes, b) how certain variables are sel...

Background: Pikes, members of genus Esox, are widespread freshwater predators of the northern hemisphere, and important sport fish also. From the Carpathian basin only one species, the northern pike (E. lucius) is noted. At the same time the pike stocks living in this area show high level of phenotypic variance (e.g. various body pattern) and its g...

Several recent notes prove that taxonomic relations of close relative animal groups (species complexes or cryptic species) can be revealed by the combined use of genetic and morphologic methodologies. At the same time scarce information can be found about how phylogeny, population origin, and sexual dimorphism affect the morphometric features of th...

A csukafélék (Esocidae) gazdasági és ökológiai szempontból is jelentős édesvízi ragadozóhalak, ugyanakkor eddig a csoport Kárpát-medencei állományairól kevés filogenetikai információ állt rendelkezésre. Az összesen 49 mintahelyről begyűjtött 88 csukaegyed mtCytb és mtDloop szekvenciáin elvégzett elemzéseink eredményei szerint a Kárpát-medencében cs...

Recent researches suggest that functional diversity represents the response of communities to environmental alterations better than taxonomic diversity. However, there is scarce information about how the functional diversity of freshwater fishes is affected by habitat type and the dominance of non-native species. To address this question, we analys...

During traditional distance-based morphometric studies, the measurer usually try to record as many variables as possible. But on the one hand, the implementation of these works is a time-and energy-consuming task, and on the other hand, the recorded variables are not always informative from the aspect. of the group separation. Moreover there is a l...

This study presents the first occurrence and recent distribution pattern of the river nerite (Theodoxus fluviatilis L. 1758) in Lake Balaton. The first appearance of this Prosobranch snail was recorded along the western shore of the Tihany peninsula situated on the middle section of the lake, at 21 st of October 2013 during a routine macrozoobentho...

Az országos léptékű halállomány-felméréseink során számos esetben fogtunk atipikus megjelenésű csukákat. Az egyedek mintázata és oldalvonalbeli pikkelyszáma eltért az E. lucius fajnál megadottaktól, viszont nagyban hasonlóak az olasz és francia vizekből újonnan leírt csukafajokéhoz. Emiatt egy különálló csuka klád jelenlétét valószínűsítjük a magya...
