Assessment of Bottom Trawl Impacts on the Status of Seabed Communities in European Seas

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 285-299, March 2026.
ABSTRACT Bottom trawling affects seabed habitats, but its large‐scale impacts remain poorly quantified. Assessment of trawling impacts is essential to support monitoring and achieving sustainability objectives under international conventions, sustainable development goals, and seafood certification programs.

Hochdrucksynthese von Antimonnitrid Sb3N5 und Polynitrid Sb2N8 mit einfach gebundenen N810− Ketten

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Hochdrucksynthesen zwischen Antimon und molekularem Stickstoff in einer laserbeheizten Diamantstempelzelle führten zur Bildung von oC32‐Sb3N5 (51(1) GPa) und mP20‐Sb2(N8) (> 100 GPa). Beide Phasen wurden mittels Einkristall‐Röntgenmikrodiffraktion identifiziert und durch Berechnungen mittels Dichtefunktionaltheorie vollständig bestätigt.

Partitioning between primary and secondary metabolism of carbon allocated to roots in four maize genotypes under water deficit and its effects on productivity

open access: yesCrop Journal, 2015
Plants may respond to drought by altering biomass allocation to shoots and roots or by changing the metabolic activities in these organs. To determine how drought changes the partitioning of carbon allocated to growth and secondary metabolism in maize ...

WABAD: A world annotated bird acoustic dataset for passive acoustic monitoring

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers.

Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

open access: yesIrrigation and Drainage, Volume 75, Issue 1, Page 411-424, February 2026.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...
