A binary nature of the marginal CP star Sigma Sculptoris [PDF]

open access: yes, 2018
The A2 V star σ Scl was suspected of being a low-amplitude rotating variable of the Ap-type star by several authors. Aiming to decide whether the star is a variable chemically peculiar (CP) star, we searched for the photometric and spectroscopic ...

Whole genome sequencing of historical specimens from the world's largest fungal collection yields high‐quality assemblies

open access: yesNew Phytologist, EarlyView.
Summary High‐throughput molecular studies of museum specimens (museomics) have great potential in biodiversity research, but fungal historical collections have scarcely been examined, leading to no comprehensive methodological assessments. Here we present a whole genome sequencing (WGS) project conducted at the Fungarium of the Royal Botanic Gardens ...

Beyond species means – the intraspecific contribution to global wood density variation

open access: yesNew Phytologist, EarlyView.
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Microbial influence on the formation and subsequent changes of vertebrate tracks: field experiments on present‐day coastal sediments

open access: yesSedimentology, EarlyView.
ABSTRACT The presence of microbial mats is often invoked to explain the good preservation of vertebrate tracks, because they can cover and biostabilize such structures. However, microbial influence on the sediment properties when the track is made and on the track characteristics has not been so thoroughly analysed.

Near‐Synchronous Cambrian Evolution of the Transbrasiliano‐Kandi‐4°50′ Shear Zone in South America and Africa

open access: yesTerra Nova, EarlyView.
ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

Distinct expressions of the BSR using various frequencies offshore Uruguay and its correspondence with the gas hydrate stability zone [PDF]

open access: yes, 2011
At the Uruguayan continental margin, seismic evidence for the occurrence of gas hydrate has been identified based on the presence of BSRs in densely spaced 2D reflection seismic sections from different surveys.

First palynologic record of the Cretaceous La Yesera Formation (Salta Group), northwestern Argentina [PDF]

open access: yes, 2014
Thirty-four taxa were documented from six palynologically productive samples of the La Yesera Formation (Brealito and Don Bartolo Members) in the Pucará locality (Salta Province, northwestern Argentina).

Nutrients, Metals, and Carbon in Soils Irrigated With Treated Versus Untreated Wastewater

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 131-142, February 2026.
Transitioning from untreated to treated wastewater irrigation reduced soluble N and P but enhanced Cr, Fe and Ni mobilization in long‐term wastewater‐irrigated Mezquital Valley soils, highlighting soil‐type‐dependent effects. ABSTRACT Background Reuse of wastewater for irrigation can mitigate pressure on water resources and support closing nutrient ...

Modelo de anegamiento y estrategia de predicción-prevención del riesgo de inundación en áreas de llanura: el sudeste de la provincia de Buenos Aires como caso de estudio [PDF]

open access: yes, 2013
En el sector sudeste de la provincia de Buenos Aires se encuentra la llanura interserrana bonaerense, limitada por los sistemas serranos de Tandilla y Ventania, dedicada casi exclusivamente a la producción agrícola.

Reconstructing Late Pleistocene to Prehistorical Holocene Geomagnetic Field Variations From La Palma Lava Flows (Canary Islands, Spain): Unraveling Viscous Components

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.
