Varying degradation of subfossil Daphnia longispina during the past 250 years and the discovery of fossil helmet-type head shields: preliminary results

Advances in Oceanography and Limnology, 2016
Zooplankton are regarded as a good indicator of environmental change, but comprehensive monitoring programs including  zooplankton are uncommon and only rarely extend over longer periods of time.

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations

Journal of Fish Biology, EarlyView.
Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.

Két tiszai holtmeder Cladocera közösségeinek összehasonlító vizsgálata [PDF]

, 2019
Dolgozatomban szó van a holtmedrek kialakulásáról, a Cladocera közösségek jelentőségéről és azopk vizsgálatának menetésről. Célom az volt hogy összehasonlítsak két azonos hazsnosítású holtmedred ezen csoportokat vizsgálva.

Cladocera fajösszetétel összehasonlítása két Felső–Tisza vidéki holtmederben [PDF]

, 2017
Vizsgálatunk célja volt a Felső–Tisza vidéken található holtmedrek Cladocera fajösszetételének megismerése. Célunk volt továbbá megvizsgálni, hogy a Cladocera fajösszetétel alapján felfedezhető–e különbség a két eltérő, természetvédelmi oltalom alatt ...

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, Volume 33, Issue 4, Page 784-798, August 2026.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

A Hidrológiai Közlöny ágascsápú rákokkal (Cladocera) kapcsolatos közleményei (1940-2013) [PDF]

, 2016
A dolgozat megírásához a Hidrológiai Közlöny publikációt használtuk fel, melyek elektronikusan elérhetőek a Magyar Hidrológiai Társaság honlapján. A honlapon lehetőség van kulcsszavas keresésre, ezáltal kiszűrtük a Cladocera-król szóló publikációkat.
