Understorey species distinguish late successional and ancient forests after decades of minimum human intervention
Mirjana Šipek, Tim Ravnjak, Nina Šajna
Izvirni znanstveni članek
Oznake: forest community;successional forest;indicator plants;plant diversity;understorey;geophyte;Slovenia;ne zaključna dela;
The main species composition drivers in temperate deciduous forests are environmental conditions, a stand's age and the site history, e.g., the succession stage and past land use, as well as disturbance regime and current management. We compared plant species diversity and composition in late succes ...

Combined toxic effects of BPA and its two analogues BPAP and BPC in a 3D HepG2 cell model
Martina Štampar, Tim Ravnjak, Ana-Marija Domijan, Bojana Žegura
Izvirni znanstveni članek
Oznake: BP analogues;hepatic in vitro 3D cell model;combined exposure;viability;oxidative stress;toxicology;
Bisphenol A (BPA) is one of the most commonly used substances in the manufacture ofvarious everyday products. Growing concerns about its hazardous properties, including endocrinedisruption and genotoxicity, have led to its gradual replacement by presumably safer analogues inmanufacturing plastics. T ...
