Peatland Development, Vegetation History, Climate Change and Human Activity in the Valdai Uplands (Central European Russia) during the Holocene: A Multi-Proxy Palaeoecological Study

Diversity, 2020
Peatlands are remarkable for their specific biodiversity, crucial role in carbon cycling and climate change. Their deposits preserve organism remains that can be used to reconstruct long-term ecosystem and environmental changes as well as human impact in

Sedimentary ancient DNA from Lake Skartjorna, Svalbard: assessing the resilience of arctic flora to Holocene climate change [PDF]

, 2015
Reconstructing past vegetation and species diversity from arctic lake sediments can be challenging because of low pollen and plant macrofossil concentrations. Information may be enhanced by metabarcoding of sedimentary ancient DNA (sedaDNA). We developed

Shoreline and deglaciation chronology in southeast Norway

Boreas, EarlyView.
The postglacial relative sea level history is reconstructed in four areas of mid‐ and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon‐dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit.

Arlenea delicata gen. et sp. nov., a new ephedroid plant from the Early Cretaceous Crato Formation, Araripe Basin, Northeast Brazil

Plant Diversity
Ephedroid macrofossils have been widely documented in Cretaceous deposits, including numerous from the Lower Cretaceous Yixian Formation of NE China. However, few ephedroid macrofossils have been reported from South America.

Long-distance dispersal of plant macrofossils [PDF]

New Zealand Journal of Botany, 1980
Abstract Evidence is presented for the long-distance transport of leaves or other plant fragments by streams and/or by flotation on lakes and/or by wind. Under some circumstances macroscopic floras could be transported over considerable distances before being deposited and fossilised.

Untangling nutrient co‐regulation of ombrotrophic peatland development

Boreas, EarlyView.
Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...

Early to Mid Wisconsin fluvial deposits and palaeoenvironment of the Kidluit Formation, Tuktoyaktuk Coastlands, western Arctic Canada [PDF]

, 2017
The Kidluit Formation (Fm) is a fluvial sand deposit that extends regionally across the Tuktoyaktuk Coastlands, western Arctic Canada. It was deposited by a large river flowing north into the Arctic Ocean prior to development of a cold-climate sandy ...

Restoring the lost Ericaceae of Botany Bay's scrublands through a paleoecological approach in southeastern Sydney, Australia

Restoration Ecology, EarlyView.
Abstract Introduction With anthropogenic environmental change accelerating, incorporating long‐term perspectives into ecological restoration is essential. Paleoecological evidence increasingly indicates that many perceived “natural” landscapes under current conservation regimes are, in fact, cultural or modern systems.

Late Holocene palynology and palaeovegetation of tephra-bearing mires at Papamoa and Waihi Beach, western Bay of Plenty, North Island, New Zealand. [PDF]

, 1995
The vegetation history of two mires associated with Holocene dunes near the western Bay of Plenty coast, North Island, New Zealand, is deduced from pollen analysis of two cores.
