Floodplain environmental change during the younger dryas and holocene: Evidence from the lower kennet valley, south central England [PDF]

, 2006
Many lowland rivers across northwest Europe exhibit broadly similar behavioural responses to glacial-interglacial transitions and landscape development. Difficulties exist in assessing these, largely because the evidence from many rivers remains limited

Airborne pollen calendar of Portugal: a 15-year survey (2002–2017)

Allergologia et Immunopathologia, 2020
Data about the occurrence of airborne pollen enables the creation of pollen calendars with an approximation of flowering periods for the most common allergenic plant species in a specific area. The aim of this work is to provide pollen calendar for each of the seven monitoring regions of Portugal based on 15 years of airborne sampling, in order to ...

Shifts in Fossil Benthic Foraminiferal Community Trajectories During the Last Deglaciation Along the European Margin

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract Constraining how faunal communities vary over time and space in response to environmental change has long been a major goal of paleoecologists. Among fossilized organisms, few yield a better and greater detailed record than foraminifera to understand past marine conditions.

Towards rainy high Arctic winters: How experimental icing and summer warming affect tundra plant phenology, productivity and reproduction

Journal of Ecology, Volume 114, Issue 1, January 2026.
Extreme rain‐on‐snow events forming basal‐ice can shape high Arctic plant communities as strongly as summer warming. Icing delays soil warming and early growth but compensatory responses follow, at the cost of reproduction. Summer warming offsets most icing impacts, enhancing growth and reversing phenological delays, though inflorescence remains ...

Multidisciplinary approach to reconstructing local pastoral activities: an example from the Pyrenean Mountains (Pays Basque) [PDF]

, 2009
International audienceIn this study archaeology, history and palaeoecology (modern and fossil data sets of pollen and nonpollen palynomorphs) were used to reconstruct small-scale pastoral activities in the Pyrenees Mountains during the last two millennia.

Fire‐induced disturbances in Malpighiaceae sequential flowering: Implications for pollination services and plant reproductive success

Plant Species Biology, Volume 41, Issue 1, January 2026.
Our study demonstrates that fire has a strong influence on flowering phenology and reproductive dynamics in Malpighiaceae species from the Brazilian Cerrado. Specifically, fire triggered an earlier onset of flowering and promoted a more synchronous and widespread blooming, resulting in a temporary surge in floral resource availability. This increase in

Reconstructing the accumulation history of a saltmarsh sediment core: which age-depth model is best? [PDF]

, 2017
Saltmarsh-based reconstructions of relative sea-level (RSL) change play a central role in current efforts seeking to quantify the relationship between climate and sea-level rise.

Airborne pollen calendar of Lublin, Poland.

Annals of agricultural and environmental medicine : AAEM, 2004
Pollen concentration in the atmosphere of Lublin (eastern Poland) was studied by means of volumetric method using Hirst sampler (VPPS 2000, Lanzoni) in 2001-2002. The pollen trap was mounted at the height of 15 m in the centre of Lublin. On the basis of analysis of mean daily values of pollen concentration, the pollen calendar was constructed for 16 ...

Contribution to Early Holocene vegetation and climate history of Eastern Orinoco Llanos, Venezuela, from a paleoecological record of a Mauritia L.f. swamp Contribuição para a história da vegetação e clima durante o Holoceno Temprano do Llanos Orientais do Orinoco, Venezuela, a partir de um registro paleoecológico de um pântano Mauritia L.f.

Acta Amazonica, 2011
A palynological analysis of an organic paleosol found at 150-125 cm depth in a Mauritia swamp from the Eastern Orinoco Llanos is presented. The 25 cm pollen record summarizes the vegetation history during the Early Holocene, from 10,225 to 7,800 calendar
