Diseases can have conspicuous consequences, such as mass mortality events, but may also exert covert but similarly severe effects, such as sex ratio distortion via sex‐biased mortality. Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd) is among the most important threats to amphibian biodiversity. Yet, whether Bd infection can skew sex ratios in amphibians is currently unknown, although such a hidden effect may cause the already dwindling amphibian populations to collapse. To investigate this possibility, we collected common toad ( Bufo bufo ) tadpoles from a natural habitat in Hungary and continuously treated them until metamorphosis with sterile Bd culture medium (control), or a liquid culture of a Hungarian or a Spanish Bd isolate. Bd prevalence was high in animals that died during the experiment but was almost zero in individuals that survived until the end of the experiment. Both Bd treatments significantly reduced survival after metamorphosis, but we did not observe sex‐dependent mortality in either treatment. However, a small number of genotypically female individuals developed male phenotype (testes) in the Spanish Bd isolate treatment. Therefore, future research is needed to ascertain if larval Bd infection can affect sex ratio in common toads through female‐to‐male sex reversal.}, year = {2024}, eissn = {2045-7758}, orcid-numbers = {Ujhegyi, Nikolett/0000-0001-9610-0353; Mikó, Zsanett/0000-0003-4853-9331; Kásler, Andrea/0000-0003-2075-0776; Bókony, Veronika/0000-0002-2136-5346} } @CONFERENCE{MTMT:34685680, title = {Növényvédelemben és szúnyoggyérítésben gyakran alkalmazott piretriod rovarirtók szubletális hatásai barna varangyokra}, url = {https://m2.mtmt.hu/api/publication/34685680}, author = {Mikó, Zsanett and Ujhegyi, Nikolett and Kásler, Andrea and Bókony, Veronika}, booktitle = {70.

The mechanisms translating environmental stimuli to sex are controversial: although several fish experiments supported the mediator role of glucocorticoid hormones, results on some reptiles challenged it. We tested this hypothesis in amphibians by investigating the effect of corticosterone on sex determination in agile frogs ( Rana dalmatina ). This species is liable to environmental sex reversal whereby genetic females develop into phenotypic males. After exposing tadpoles during sex determination to waterborne corticosterone, the proportion of genetic females with testes or ovotestes increased from 11% to up to 32% at 3 out of 4 concentrations. These differences were not statistically significant except for the group treated with 10 nM corticosterone, and there was no monotonous dose‐effect relationship. These findings suggest that corticosterone is unlikely to mediate sex reversal in frogs. Unexpectedly, animals originating from urban habitats had higher sex‐reversal and corticosterone‐release rates, reduced body mass and development speed, and lower survival compared to individuals collected from woodland habitats. Thus, anthropogenic environments may affect both sex and fitness, and the underlying mechanisms may vary across ectothermic vertebrates.}, year = {2024}, eissn = {2471-5646}, pages = {172-181}, orcid-numbers = {Bókony, Veronika/0000-0002-2136-5346; Gabor, Caitlin R./0000-0001-7584-1451} } @{MTMT:34547682, title = {A kémiai növényvédelem egy meglepő kockázata: fiúkból lányok, lányokból fiúk?}, url = {https://m2.mtmt.hu/api/publication/34547682}, author = {Bókony, Veronika and Ujhegyi, Nikolett and Mikó, Zsanett}, booktitle = {Tudományos kutatások a környezetbarát növényvédelemért a HUN-REN ATK Növényvédelmi Intézetében}, unique-id = {34547682}, year = {2023}, pages = {12-16}, orcid-numbers = {Bókony, Veronika/0000-0002-2136-5346} } @{MTMT:34547623, title = {Egy glifozátalapú gyomirtó ökotoxikológiai hatásai a vízi szervezetekre}, url = {https://m2.mtmt.hu/api/publication/34547623}, author = {Mikó, Zsanett and Bókony, Veronika and Ujszegi, János and Hettyey, Attila}, booktitle = {Tudományos kutatások a környezetbarát növényvédelemért a HUN-REN ATK Növényvédelmi Intézetében}, unique-id = {34547623}, year = {2023}, pages = {8-11}, orcid-numbers = {Bókony, Veronika/0000-0002-2136-5346} } @article{MTMT:33750371, title = {Do glucocorticoid hormones mediate sex reversal in frogs?}, url = {https://m2.mtmt.hu/api/publication/33750371}, author = {Ujhegyi, Nikolett and Kalina, C. and Mikó, Zsanett and Bókony, Veronika}, journal-iso = {INTEGR COMP BIOL}, journal = {INTEGRATIVE AND COMPARATIVE BIOLOGY}, volume = {62}, unique-id = {33750371}, issn = {1540-7063}, year = {2023}, eissn = {1557-7023}, pages = {S312-S313}, orcid-numbers = {Bókony, Veronika/0000-0002-2136-5346} } @CONFERENCE{MTMT:33661348, title = {A klímaváltozás és két piretroid rovarölőszer együttes hatásai juvenilis barna varangyok (Bufo bufo) fejlődésére és túlélésére}, url = {https://m2.mtmt.hu/api/publication/33661348}, author = {Kásler, Andrea and Bókony, Veronika and Mikó, Zsanett and Herczeg, Dávid and Ujszegi, János and Holly, Dóra and Hettyey, Attila}, booktitle = {69.
