When studying the well-being and fitness of ichthyofauna in a specific area, vital information comes from length–weight relationships (LWRs) and condition factor analyses and calculations. Data were collected from 2015 to 2019 in an area important for fish shelter, feeding, and spawning. Twenty four species belonging to 10 different families were identified from the total 16,895 of caught individuals, with the most abundant species being Blicca bjoerkna. The calculation of LWRs was possible for 19 species, (R² = 0.7049–0.9998 (p < 0.05)), with the values of the mean coefficient b ranging from 2.6831 to 3.5747, indicating an overall positive allometric growth in the fish population. The results of Fulton’s and the relative condition factors showed that a total of eight species were in a relatively good condition, although the species in question varied between the two condition factors. Fulton’s condition factor showed the highest average value for Lepomis gibbosus (1.4956), while Cobitis elongatoides had the lowest (0.4739). Contrarily, the relative condition factor showed the highest average value for Silurus glanis (1.0524), and the lowest for Gymnocephalus cernua (1.0023). The lower values of calculated condition factors in some species could be attributed to sampling being conducted during the colder months of autumn and winter. Future studies should include seasonal sampling in order to achieve a better understanding how various abiotic factors impact the condition factors of these fish species. Nevertheless, this research provided valuable data on the status of the fish population in the floodplain and could be used as a guideline for designing future ichthyofauna studies in this area.

Tijekom 2014. godine provedeno je istraživanje saproksilnih kornjaša unutar različitih šumskih zajednica na području Parka prirode Kopački rit. Utvrđena je prisutnost 64 vrste. Vrste Cucujus cinnaberinus (Scopoli, 1763) i Rhysodes...

Plodovi čivitnjače (Amorpha fruticosa L.), invazivne biljne vrste, prikupljani su tijekom 2017. godine na području Pokupskog bazena i u Županji. Na plodovima žljezdastim mahunama uočeni su izletni otvori te je utvrđena prisutnost invazivne vrste kukca Acanthoscelides pallidipennis (Motschulsky, 1873). Ova je vrsta autohtona na području Sjeverne Amerike, a njezina rasprostranjenost usko je vezana uz staništa čivitnjače i puteve širenja ove invazivne biljne vrste. Na području Pokupskog bazena u prikupljenim su uzorcima zabilježene ukupno 554 infestirane mahune, dok su u Županji bile infestirane 434 mahune te nije utvrđena statistički značajna razlika između dvaju istraživanih područja. Rezultati ukazuju na to da je kukac A. pallidipennis raširen u sastojinama čivitnjače na obama područjima te da je potrebno pratiti potencijal njegova širenja kako bi se spriječila infestacija i drugih biljnih vrsta, posebice onih iz porodice Fabaceae koje učestalo napada.
