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 ...

Modelling transverse dunes

open access: yes, 2003
Transverse dunes appear in regions of mainly unidirectional wind and high sand availability. A dune model is extended to two dimensional calculation of the shear stress.

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas

open access: yesThe Journal of Wildlife Management, EarlyView.
Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.

Seasonality and Small Spatial-Scale Variation of Chlorophyll a Fluorescence in Bryophyte Syntrichia ruralis [Hedw.] in Semi-Arid Sandy Grassland, Hungary

open access: yesPlants, 2020
Bryophytes face challenges due to global climate change which is leading to in-depth research in monitoring and studying their photosynthetic activity. The aim of this preliminary experiment was to study the seasonal variation trend in the chlorophyll a ...

First Demonstration of a Pixelated Charge Readout for Single-Phase Liquid Argon Time Projection Chambers

open access: yes, 2018
Liquid Argon Time Projection Chambers (LArTPCs) have been selected for the future long-baseline Deep Underground Neutrino Experiment (DUNE). To allow LArTPCs to operate in the high-multiplicity near detector environment of DUNE, a new charge readout ...

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

A Study of Invisible Neutrino Decay at DUNE and its Effects on $\theta_{23}$ Measurement

open access: yes, 2018
We study the consequences of invisible decay of neutrinos in the context of the DUNE experiment. We assume that the third mass eigenstate is unstable and decays to a light sterile neutrino and a scalar or a pseudo-scalar.
