Introduction
I am a researcher with the interest of reproduction behaviour of arthropod (Crayfish, Spider and Mantis etc.). I am with the background of Fisheries and conservation biology in freshwaters, biological invasions, interactions of native and non-native biota.The topic of my PhD is the burrowing behaviour in crayfish.

The spread of non-native species results in novel and often unexpected assemblages. Using stable isotopes, we disentangled the trophic relationships between three invasive crayfish species at two sites of a small thermal tributary of the Barát stream, Hungary. We studied Procambarus virginalis and Faxonius limosus living in sympatry in the upper se...
Article
Despite their low concentrations in many aquatic environments, evidence exists to suggest that herbicides do affect non-target organisms. Given that burrowing is a primary life-history trait in crayfish, herbicides could potentially have serious negative effects on these ecologically important freshwater macroinvertebrates. In this study, we expose...
Article
Pharmaceutically active compounds (PhAC) have been increasingly detected in freshwater and marine waterbodies worldwide and are recognized as major emerging micropollutant threat to the aquatic environment. Despite their low concentrations in the environment, there is evidence of effects on non-target aquatic organisms in natural habitats. To asses...
Article
Full-text available
Pharmaceutically active compounds (PhACs) are ubiquitous in the aquatic environment worldwide and considered emerging contaminants. Their effects on growth, behavior, and physiological processes of aquatic organisms have been identified even at very low concentrations. Ecotoxicological investigations have primarily focused on single compound exposu...
Article
Full-text available
Biological invasions are a growing threat to global biodiversity due to negative impacts on native biota and ecosystem functioning. Research has expanded from investigating native and alien species interactions to examining relationships among alien species. Invasive crayfish may have similar life histories, niche preferences, and adaptation strate...
Article
Full-text available
Interactions occurring between species in multiple invaded freshwater ecosystems are often difficult to observe and study. Studies on invasive alien species typically focus on single species, and, when the species community is exclusively composed of alien species, their interactions, eventual facilitation and hindering processes are very scarcely...

1. Severe weather events, such as long-term droughts, are challenging for many freshwater species. To survive drought, freshwater crayfish tend to inhabit shelters or burrows where they can remain in contact with water or high humidity environments. However, it is not known whether embryogenesis or post-embryonic development can occur without free...
Article
Pharmaceutically active compounds are major contaminants of aquatic environments that show direct and indirect effects on aquatic organisms even at low concentrations. The aim of this study was to assess the effects of the illicit drug methamphetamine and the antidepressant sertraline on clonal marbled crayfish Procambarus virginalis. Crayfish expo...

The objective of this study was to describe the morphology and ultrastructure of Acipenser dabryanus spermatozoa using both scanning electron microscope and transmission electron microscopy. The spermatozoon was consisted of an elongated head with a distinct acrosome, nucleus, mid‐piece, and a flagellum. The total length of the acrosome, nucleus, a...

Red swamp crayfish Procambarus clarkii: economic importance but also environmental threat
Article
Full-text available
Conventional sperm analysis (i.e., motility and fertility) has been used to evaluate sperm quality. Understanding the quality of sperm on the molecular level in the sturgeons, Acipenser baerii and A. schrenckii, is essential for the improvement of the conservation of genetic resources and farming performance. In this study, we used the iTRAQ proteo...

The present study was designed to evaluate the use of microsatellite markers to identify parentage in Brachymystax lenok tsinlingensis, an endangered species of salmonid fish. Computer simulations showed that when no parent information was available, or when information was only available from one parent, then exclusion probabilities ranged from 23...
Article
This study was conducted to investigate the morphology and ultrastructure of Hucho bleekeri Kimura spermatozoa through scanning and transmission electron microscopy. The results revealed that the spermatozoa can be differentiated into three major parts: a head, a mid-piece, and a flagellum. The mean length of the spermatozoa was 41.07 μm ± 2.18 μm,...
Article
This study was conducted to investigate Brachymystax lenok tsinlingensis spermatozoa cell morphology and ultrastructure through scanning and transmission electron microscopy. Findings revealed that the spermatozoa can be differentiated into three major parts: a spherical head without an acrosome, a short mid-piece, and a long, cylindrical flagellum...

This study investigated the diet compositions of Coreius heterodon and C. guichenoti in Yibin reach of Yangtze River from April to May, 2012 by carbon and nitrogen stable isotopes technique, and analyzed their diet relationship by the multivariate statistical technique, which covered the diet similarity index, overlap coefficient, and the influence...

Dear astacologists, On behalf of the official organizing committee, the International Association of Astacology, and the hosting institution, the Faculty of Fisheries and Protection of Waters, University of South Bohemia, as well as the Organizing and Scientific committee, I would hereby like to cordially invite you to the IAA 23 Symposium, which will be held in the beautiful South Bohemia Region of the Czech Republic from 20 - 26 June 2022. The Symposium will be held in the grand Hotel Štekl, located in close proximity to the beautiful Hluboká nad Vltavou Château, from where you will be able to appreciate the local atmosphere. This event will be focused on any crayfish-related topic including species diversity and distribution, conservation, physiology, genetics, ecology, ethology, diseases, fishery and aquaculture. We promise not only a quality scientific program with several keynote speakers, but also a carefully prepared social program including trips to the experimental facilities of the FFPW USB, natural crayfish locality in the Šumava National Park, the Hluboká nad Vltavou Château, beer tasting with the Budweiser Budvar Brewery, the Český Krumlov UNESCO Heritage castle and wooden rafting. We believe the program will be interesting for both delegates and accompanying personnel. Important dates: Early registration: till March 31, 2022 Abstract submission: till April 22, 2022 Regular registration: till April 30, 2022 Late registration: till May 31, 2022 For more information see: www.iaa23.com Yours sincerely, Pavel Kozák Dean of FFPW USB Board Member of IAA iaa23@frov.jcu.cz
