Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

Managing the margins: Practitioner perspectives on barriers and solutions for biodiversity‐friendly roadside management in Germany

People and Nature, EarlyView.
Abstract Roadsides can provide habitats, refuges and corridors for various plant and insect species. Preserving and enhancing these ecosystems can mitigate biodiversity loss and improve connectivity in fragmented landscapes. Despite growing evidence supporting biodiversity‐friendly management strategies, large‐scale implementation has not been realized.

Information is primary and central to meaning-making

Sign Systems Studies
There is the misconception that the concept of information is not applicable to meaning-making in living beings. What is more generally believed is that Peircean semiosis provides a more robust framework to explain meaning-making.

Defect Passivation via Plasma Modification of Lead Halide Perovskite Thin Films

Progress in Photovoltaics: Research and Applications, EarlyView.
We demonstrate that exposure of perovskite thin films to diffuse coplanar surface barrier discharge nitrogen plasma leads to an increase in photoluminescence, attributed to reduced defect densities. This results in implied open‐circuit voltage improvement of up to 80 mV and finalized solar cell open‐circuit gains up to 60 mV.

Of bubbles and foams: Umwelt counterpoints in symbiosis

Sign Systems Studies
In recent years, our aim has been to expand the concept of ‘umwelt’ towards its evolutionary aspects. In this contribution, we argue that since the different lineages of life share their origins, they also share, at least to some extent, the ...

Zukunftstechnologien bei der Stromerzeugung: Elektrizität im internationalen Vergleich

Physik in unserer Zeit, EarlyView.
Welche Technologien setzen sich bei der Stromerzeugung gerade durch? Die Antwort sieht man eindeutig in den Trends von weltweiten Stromerzeugungsdaten. Analysiert man diese Daten mithilfe der Theorie der Diffusion von Innovationen, dann zeigt sich, wie Photovoltaik und Wind sich weltweit durchsetzen.

Herbarium digitisation sheds light on historical distribution and drivers of population extinction of a peat bog specialist

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity loss threatens ecosystem services and human well‐being. Understanding the extent and causes of changes in biodiversity over time can help protect species and their habitats. Herbaria house carefully documented and curated specimens collected by generations of botanists.

Injury Risks to a Migratory Freshwater Fish During Downstream Passage Through a Regulated Floodplain Outlet: A Case Study on Golden Perch (Macquaria ambigua)

River Research and Applications, EarlyView.
ABSTRACT River infrastructures such as weirs, dams, inlet and outlet regulators often impair connectivity, leading to degradation and loss of key habitats for riverine fishes. This also holds true for golden perch (Macquaria ambigua Richardson), a migratory species in Australia's Murray–Darling Basin.
