“…This debate is still ongoing, despite a growing body of evidence from historical and palaeoecological studies that point to the native origin of these regional stone pine forests (Martínez and Montero, 2004). In Southwest Iberia, macrofossil and palynological records show the presence of stone pine for at least the last 50 kyr (Stevenson, 1984(Stevenson, , 1985López-Sáez et al, 2001, 2002aCarrión et al, 2008), suggesting the permanence of widespread coastal pine woodlands since the Upper Pleistocene. Pinus pinea type is present in the S1 pollen record from the mid-Holocene ~ 5000 cal BP ( Fig.…”

A multi-proxy palaeoenvironmental study (pollen, non-pollen palynomorphs, charcoal particles, mollusk macrofauna) of coastal marshland in Doñana National Park (southwestern Iberian Peninsula) was undertaken to trace environmental change, human activities related to woodland clearance, and past land-use during the mid-late Holocene (~ 5000-2800 cal BP). The results of this study are combined with archaeological data from the Copper and Bronze Ages and are subsequently compared with those of similar research carried out at the south-westernmost part of Europe with the aim of discerning regional differences or similarities. Our research has allowed us to recognize climate changes and four extreme wave events in the Guadalquivir paleoestuary, which might have contributed to both the cultural change that is observed in the archaeological record at the end of the Chalcolithic and the subsequent population decline during much of the Bronze Age.

“…This region is considered a hotspot of biodiversity (Médail and Quézel, 1999) as well as a climate change "hotspot" (Giorgi and Lionello, 2008). Recent research has highlighted possible anthropogenic influences along with the, often hard to separate, climatic signal through palaeoenvironmental reconstruction, such as to the west (Carrión et al, 2007;Estiarte et al, 2008;López Sáez et al, 2002;Pantaléon-Cano et al, 2003), centrally (Bellini et al, 2009;Calò et al, 2012;Combourieu Nebout et al, 2013;Di Rita and Magri, 2012;Noti et al, 2009;Sadori et al, 2013b;Tinner et al, 2009), as well as in eastern areas (Bottema and Sarpaki, 2003;Finkelstein and Langgut, 2014;Hajar et al, 2010;Jahns, 2005;Kaniewski et al, 2014;van Zeist et al, 2009).…”

7300 years of vegetation history and climate for NW Malta: a Holocene perspective

et al. 2016

Abstract. This paper investigates the Holocene vegetation dynamics for Burmarrad in Northwest Malta and provides a pollen-based quantitative palaeoclimatic reconstruction for this centrally located Mediterranean archipelago. The pollen record from this site provides new insight into the vegetation changes from 7280 to 1730 cal BP which correspond well with other regional records. The climate reconstruction for the area also provides strong correlation with southern (below 40 • N) Mediterranean sites. Our interpretation suggests an initially open landscape during the early Neolithic, surrounding a large palaeobay, developing into a dense Pistacia scrubland ca. 6700 cal BP. From about 4450 cal BP the landscape once again becomes open, coinciding with the start of the Bronze Age on the archipelago. This period is concurrent with increased climatic instability (between 4500 and 3700 cal BP) which is followed by a gradual decrease in summer moisture availability in the late Holocene. During the early Roman occupation period (1972-1730 cal BP) the landscape remains generally open with a moderate increase in Olea. This increase corresponds to archaeological evidence for olive oil production in the area, along with increases in cultivated crop taxa and associated ruderal species, as well as a rise in fire events. The Maltese archipelago provides important insight into vegetation, human impacts, and climatic changes in an island context during the Holocene.

Climate conditions most likely became more humid, as percentages of mesic tree taxa (deciduous Quercus, Abies pinsapo, Ulmus and Populus ) increase (Anderson et al, 2011; Carrión, 2002; Cortés-Sánchez et al, 2008; Florschütz et al, 1971; Guilloy-Froget et al, 2002; López-Sáez et al, 2002) (Figure 3).

“…At Lake Medina, the time around 3 cal. ka BP is characterized by lowered occurrences of riparian taxa like Ulmus and Populus , but also by increases in thermophilous Mediterranean Phillyrea pollen, rather pointing towards lowered precipitation (Figure 3) (Abel-Schaad et al, 2018; Carrión, 2002; Guilloy-Froget et al, 2002; López-Sáez et al, 2002, 2009) instead of human influence.

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.
