“…ka BP, Lake Medina sediments show indices of the maximum lake level (Schröder et al, 2018). At our study site, this implies the highest lake water salinity values related to erosion of the catchment area, consisting of Triassic evaporites (Reed et al, 2001; Schröder et al, 2018; van’t Hoff et al, 2016), influencing the occurrence of HH plants within the lake.…”

“…A description of identified non-pollen palynomorphs has been added to the palynological analysis as they give valuable additional information of the palaeolake system (Carrión and Navarro, 2002). Detailed information about the sedimentological, geochemical and mineralogical characteristics of the studied archive can be found in van’t Hoff et al (2016) (recent sedimentational processes) and Schröder et al (2018).…”

Lake Medina is a small, shallow and endorheic salt lake sensitive to climate variation in south-western Spain, close to Cádiz in western Andalusia. It is located in an evaporitic and karstic environment, and a saline lake affected by highly seasonal precipitation and evaporation. Geochemical and mineralogical data of core CO1313 combined with a robust age model show variation that contributes to the understanding of palaeoenvironmental and palaeoclimatic change. This study shows a pollen record that has been conducted on core CO1313, together with charcoal and non-pollen palynomorph analyses. The environmental and climatological history reconstruction of Lake Medina starts in early Holocene times (at 9.5 cal. ka BP) and shows intensified pasture and land use during middle-Holocene times as well as the 8.2 and 4.2 cal. ka BP abrupt climate events. Oxidation of plant remnants and resulting non-preservation at certain times reinforces the hypothesis of intense climate effects on vegetation during the 4.2 cal. ka BP climate event. Yet, oxidation of plant residues during other episodes shows other periods that were also affected by reduced precipitation. From around 2 cal. ka BP onwards, a recent trend towards aridification and enforced seasonality was detected.
