This study increases not only the knowledge of biotic assemblages in European alpine lakes, but also helps to interpret future paleolimnological studies in regions where shallow alpine lakes of arid and semiarid places exist.ġ 2 Figure captions 3 4 Fig. Positive relationships were also observed between the relative abundance of Daphnia pulex gr. sphaericus since 1970 associated with more favorable conditions for growth as a result of climate change. Our results agree with those from previous paleolimnological studies in Sierra Nevada which show an abrupt increase in the relative abundance of A. quadrangularis than in those with higher abundance of C. More favorable conditions for species growth (warmer waters and increased input of material from the catchment in small, open-basin lakes surrounded by alpine meadows) were observed in lakes with higher abundance of A. The relative abundances of Alona quadrangularis and Chydorus sphaericus showed a significant negative relationship in the lake set, suggesting the adaptation of these species to diverging lakes conditions in Sierra Nevada.

The explanatory power of chemical parameters was lower, with total nitrogen (TN) being the most influential variable. Redundancy analyses (RDA) revealed that the distribution of cladoceran assemblages was mainly associated with morphometric variables (extent of catchment vegetation in basin, lake depth and size, and the presence of inlets and outlets in basin).

Factors associated with the presence of Daphnia were also investigated.Ĭhydorids predominated in the cladoceran assemblages. Subfossil cladoceran assemblages were studied in surface sediments from 17 shallow alpine lakes in the Sierra Nevada (Spain) to evaluate relationships between species assemblages and environmental variables.
