Data from: The history of tree and shrub taxa on Bol'shoy Lyakhovsky Island (New Siberian Archipelago) since the last interglacial uncovered by sedimentary ancient DNA and pollen data
<p>Ecosystem boundaries, such as the Arctic-Boreal treeline, are strongly coupled with climate and were spatially highly dynamic during past glacial-interglacial cycles. Only a few studies cover vegetation changes since the last interglacial, as most of the former landscapes are inundated and difficult to access. Using pollen analysis and sedimentary ancient DNA (<span class="html-italic">s</span>edaDNA) metabarcoding, we reveal vegetation changes on Bol'shoy Lyakhovsky Island since the last interglacial from permafrost sediments. Last interglacial samples depict high levels of floral diversity with the presence of trees (<em><span class="html-italic">Larix</span></em>,<span class="html-italic"> <em>Picea</em></span>,<span class="html-italic"> <em>Populus</em></span>) and shrubs (<em><span class="html-italic">Alnus</span></em>, <em><span class="html-italic">Betula</span></em>, <em><span class="html-italic">Ribes</span></em>, <span class="html-italic"><em>Cornus</em>, </span>Saliceae) on the currently treeless island. After the Last Glacial Maximum, <em><span class="html-italic">Larix</span> </em>re-colonised the island but disappeared along with most shrub taxa. This was probably caused by Holocene sea-level rise, which led to increased oceanic conditions on the island. Additionally, we applied two newly developed larch-specific chloroplast markers to evaluate their potential for tracking past population dynamics from environmental samples. The novel markers were successfully re-sequenced and exhibited two variants of each marker in last interglacial samples. SedaDNA can track vegetation changes as well as genetic changes across geographic space through time and can improve our understanding of past processes that shape modern patterns.</p>

Data related to the Last Interglacial Laurentide Outburst event in the western North Atlantic
<p>Related paper: </p> <div> <div> <div> <div>Zhou, Y., McManus, J., 2022. Extensive evidence for a last interglacial Laurentide outburst (LILO) event. Geology 50, 934. <a href="https://doi.org/10.1130/G49956.1">https://doi.org/10.1130/G49956.1</a></div> </div> </div> </div> <p>Abstract: A glacial lake outburst flood or accelerated ice sheet melting some 8,200 years ago (8.2 ka) caused the largest abrupt climate change event during the Holocene. It has been proposed that this 8.2-ka event has an analog during the Last Interglacial. Here, we characterize in detail the provenance, timing, and delivery mechanism of a layer of red sediments deposited across much of the Northwest Atlantic at 125-ka. Our observations provide strong support for the occurrence of a Last Interglacial Laurentide Outburst (LILO) event that was analogous to the 8.2-ka event in all three aspects, and likely surpassed it in magnitude. The freshwater discharge associated with the 125-ka LILO event may explain a series of abrupt global changes, including a reduction of the North Atlantic Deep Water and reinvigoration of the Antarctic Bottom Water. Our findings suggest that the mechanism that triggered the LILO event may be an integral part of the deglacial sequence of events, during which the final collapse of the contiguous Laurentide Ice Sheet (LIS) takes place 3.5 – 4 kyr after full interglacial temperature is reached in the middle and high northern latitudes.</p>
