“…The NGRIP data for this period is marked by the brief lowering of δ 18 O values marking the Younger Dryas, followed by the large increase in δ 18 O values that indicate the onset of the Holocene (Fig. 3) 31 . The slow, but steady decline in the N. pachyderma sin ‰ and the steady increase in the δ 18 O lob record is also indicative of warmer sea temperatures.…”

“…These larger scale climatic records are physically far removed from conditions experienced on regional and local levels in northern Spain. Speleothem records 28 , lake sediments 29,30 , ostracod evidence from the continental shelf 31 reflect data closer to study areas, enabling regional-scale environmental reconstructions, but these are still distant from the sites occupied by human groups. More localised environmental indicators such as pollen, found within cave sites, can inform on past vegetation 32 and have been analysed in Asturian cave sites 33,34 but must be used with caution as they can be subject to taphonomic and diagenetic alterations 35,36 .…”

“…Ibex are known to have a high plasticity in the feeding strategies depending on ecological constraints 105 , and it is possible that the ibex populations were being pushed away from the ericaceous vegetation communities of the 15 N depleted heathlands and were consuming a different diet.

The Upper Palaeolithic in Europe was a time of extensive climatic changes that impacted on the survival and distribution of human populations. During the Late Glacial Maximum (LGM), southern European peninsulas were refugia for flora, fauna, and human groups. One of these refugia, the Cantabrian region (northern Atlantic Spain), was intensively occupied throughout the Upper Palaeolithic. Characterising how climatic events were expressed in local environments is crucial to understand human and animal survival. La Riera Cave (Asturias) has a rich geo-cultural sequence dating between 20.5kyr BP to 6.5kyr BP and represents an ideal location in which to explore this. Stable isotope analysis of red deer and ibex is used alongside other environmental and climatic proxies to reconstruct Late Upper Palaeolithic conditions. Results show that during the LGM, ibex adapted their niche to survive, and became a major prey species for humans. The diverse environmental opportunities offered in the high-relief and coastal environs of La Riera may help to explain the high human population levels in the Cantabrian Region throughout the Late Upper Palaeolithic. Despite fluctuating conditions, herbivores and humans had the flexibility and resilience to adapt, demonstrating the importance of southern European refugia for the survival of different species.The settlement of Europe during the Last Glacial (MIS2) period (c.30-10kyr BP) was directly affected by the climate which resulted in cycles of expansion and contraction of populations, linked to the ebb and flow of ice sheets 1-3 . Central and northern Europe during the Last Glacial Maximum (LGM) (c. 21-18kyr BP) were mostly covered by ice sheets or polar desert that pushed populations into the south, with Iberia and southwestern France, Italy and the Balkan peninsulas acting as refugial regions. Within these locations less drastic temperatures, associated with milder conditions, facilitated survival of a variety of plant and animal species 4-13 . Of these areas, the Cantabrian region, which occupies the northern Atlantic coast of the Iberian Peninsula (Fig. 1) has been demonstrated to have been a genetic refuge for salmon 14 , red deer 15 and humans 16,17 . At least 55 archaeological sites dating to the Solutrean (24kyr BP) have been recorded in the Vasco-Cantabrian region, concurrent with a large increase in the number archaeological occupation levels recorded within many sites 13,18 , indicative of a shift of surviving populations in Europe to the region 10,11,[19][20][21] . During the Magdalenian (c. 17-11.5kyr BP), a further population expansion is observed with a dramatic increase in the number of archaeological sites recorded, linked to ameliorated climatic conditions 21,22 as identified in proxies such as ice and marine cores. This region has been described as a "dynamic cultural center in the Upper Palaeolithic world of western Europe" 23 , as reflected by and, in part, due to its extensive and rich cave art and portable art. These phenomena clearly demonstrate the importance...

Understanding the transformations of the climate system may help to predict and reduce the effects of global climate change. The geological record provides a unique archive that documents the long-term fluctuations of environmental variables, such as seasonal change. Here, we investigate how seasonal variation in seawater temperatures varied in the Mediterranean Sea during the early Pleistocene, approaching the Early-Middle Pleistocene Transition (EMPT) and the beginning of precession-driven Quaternary-style glacial-interglacial cycles. We performed whole-shell and sclerochemical stable isotope analyses (δ 18 O, δ 13 C) on bivalves, collected from
