dc.description.abstractLala Mare is a high-altitude glacial lake (1800 m a.s.l.) located in the Rodna Mountains of the Eastern Carpathians, Romania. In the present study, subfossil chironomids were analysed from a 20 cm sediment sequence to reconstruct past ecological and environmental conditions. A total of 1863 head capsules, representing 26 taxa, were identified, with overall low taxonomic richness. The assemblages were mainly dominated by Tanytarsus lugens-type and Procladius sp. Hierarchical classification analysis revealed two distinct zones: The lower zone was characterized by high abundances of Tanytarsus lugens-type, whereas in the upper zone Procladius sp. became dominant, by a decline in overall diversity, suggesting enhanced productivity. Cold-adapted taxa associated with flowing water, including Diamesa, Eukiefferiella, Tvetenia, and Pseudodiamesa branickii-type, were frequent in the 1stZone, reflecting a cold inflow. In contrast, rheophilic taxa disappeared in the second zone, reflecting a shift water inflow and hydrological changes.
