Travertines associated with the Alhama-Jaraba thermal waters (NE, Spain): Genesis and geochemistry

Freshwater carbonates are interesting archives in palaeoenvironmental reconstructions. However, more studies of those systems are needed to fully understand past environments. In this work the actively-forming travertines of the Alhama-Jaraba thermal syste ...

A model of the western Laurentide Ice Sheet, using observations of glacial isostatic adjustment

Jean-Philippe Lucien Montillet

We present the results of a new numerical model of the late glacial western Laurentide Ice Sheet, constrained by observations of glacial isostatic adjustment (GIA), including relative sea level indicators, uplift rates from permanent GPS stations, contempo ...

The climate of Europe during the Holocene: a gridded pollen-based reconstruction and its multi-proxy evaluation

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins, Achille Mauri

We present a new gridded climate reconstruction for Europe for the last 12,000 years based on pollen data. The reconstruction is an update of Davis et al. (2003) using the same methodology, but with a greatly expanded fossil and surface-sample dataset and ...

The European Modern Pollen Database (EMPD) project

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins, Achille Mauri

Modern pollen samples provide an invaluable research tool for helping to interpret the quaternary fossil pollen record, allowing investigation of the relationship between pollen as the proxy and the environmental parameters such as vegetation, land-use, an ...

Drivers of Holocene Land Cover Change in Europe

Pamela Collins

The modern vegetation of Europe is a product of its history. Climate change, plant migration, and human activity have all been important drivers of Holocene (11,500 years ago to the present) vegetation dynamics, but it is difficult to disentangle the relat ...

Modern pollen rain and fungal spore assemblages from pasture woodlands around Lake Saint-Point (France)

François Gillet

Modern analogs are commonly used to investigate the relationships between modern pollen rain and the surrounding present vegetation and to improve our interpretation of fossil data. We collected modern pollen and spore rain in 18 more or less grazed and/or ...

Pollen-based continental climate reconstructions at 6 and 21 ka: a global synthesis

Basil Andrew Stansfield Davis

Subfossil pollen and plant macrofossil data derived from C-14-dated sediment profiles can provide quantitative information on glacial and interglacial climates. The data allow climate variables related to growing-season warmth, winter cold, and plant-avail ...

A rapid response of testate amoebae and vegetation to inundation of a kettle hole mire

Mariusz Lamentowicz

Our palaeoecological study covers 73 years of history (1929-2002) of a kettle hole peatland inundated by water from a nearby, dammed lake. Testate amoebae, pollen and non-pollen palynomorphs (NPPs) were used to track the shift to wetter conditions in the p ...

Multidisciplinary approach to reconstructing local pastoral activities: an example from the Pyrenean Mountains (Pays Basqueq)

Alexandre Buttler

In this study archaeology, history and palaeoecology (modern and fossil data sets of pollen and non-pollen palynomorphs) were used to reconstruct small-scale pastoral activities in the Pyrenees Mountain during the last two millennia. Modern pollen assembla ...

Large eddy simulation of pollen transport in the atmospheric boundary layer

Marc Parlange, Charles Vivant Ignacio Meneveau

This paper presents a framework to simulate pollen dispersal by the wind based on the large eddy simulation(LES) technique. Important phenomena such as the pollen emission by the plants and the ground deposition are parameterized by the lower boundary cond ...

Pollen productivity estimates and relevant source area of pollen for selected plant taxa in a pasture woodland landscape of the Jura Mountains (Switzerland)

Alexandre Buttler, Pascal Vittoz

Relevant source area of pollen (RSAP) and pollen productivity for 11 key taxa characteristic of the pasture woodland landscape of the Jura Mountains, Switzerland, were estimated using pollen assemblages from moss polsters at 20 sites. To obtain robust poll ...

Variations in leaf area index in northern and eastern North America over the past 21,000 years: a data-model comparison

Jed Oliver Kaplan

Over the past 10 years, there has been a growing debate about the relative importance of late-Quaternary variations in climate and CO2 as drivers of changes in vegetation structure. In this study, we compare new datasets of pollen-reconstructed leaf area i ...

Last millennium palaeoenvironmental changes from a Baltic bog (Poland) inferred from stable isotopes, pollen, plant macrofossils and testate amoebae

Edward Mitchell, Mariusz Lamentowicz

The Baltic coast of Northern Poland is a region of considerable potential interest for paleoclimatic studies because this region is under the influence of both oceanic and continental climates and that these two influences have likely changed through time. ...

An optical tweezer actuated, nanoaperture-grid based Optofluidic Microscope implementation method

Demetri Psaltis

We report a novel grid based Optofluidic Microscope (OFM) method where a closely spaced 2D grid of nanoapertures (diameter = 100 nm, separation = 2.5 mu m) provided patterned illumination. We achieved a one-to-one mapping of the light transmissions through ...

Cell refractive index tomography by digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Florian Charrière, Jonas Kühn, Mihaela Marian

For what we believe to be the first time, digital holographic microscopy is applied to perform optical diffraction tomography of a pollen grain. Transmission phase images with nanometric axial accuracy are numerically reconstructed from holograms acquired ...

The ecology of testate amoebae (Protists) in South-Central Alaska peatlands: building transfer function models for paleoenvironmental studies

Edward Mitchell

Testate amoebae are valuable indicators of peatland hydrology and have been used in many palaeoclimatic studies in peatlands. Because the species' ecological optima may vary around the globe, the development of transfer function models is an essential prer ...

Modern pollen-vegetation relationships in the Champsaur valley (French Alps) and their potential in the interpretation of fossil pollen records of past cultural landscapes

Alexandre Buttler

This study is an attempt to evaluate the relationships between the vegetation and the modem pollen rain as a contribution to palaeoecological research. Pollen analysis of surface moss polsters and floristic records has been undertaken for 51 sampling point ...
