A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.

Footprint areas of pollen from alder (Alnus) and birch (Betula) in the UK (Worcester) and Poland (Wrocław) during 2005–2014

open access: yesActa Agrobotanica, 2015
In this study we analyzed daily pollen concentrations of Alnus spp. and Betula spp. from Worcester, UK and Wrocław, Poland. We analyzed seasonality, annual pollen index and footprint areas for the observed pollen concentrations by using the trajectory ...

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

open access: yesOikos, EarlyView.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...
