The Feeding Ecology of Invasive Pink Salmon Juveniles in Northern Norwegian Rivers and Their Role as Prey to Native Salmonids

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Increasing numbers of invasive Pacific pink salmon (Oncorhynchus gorbuscha) are spawning in northern Norwegian rivers, leading to large numbers of juveniles migrating to coastal waters. This raises concerns about food competition with native salmonids in rivers, although details about the timing and intensity of pink salmon feeding and the ...

Legacy effects of 41 years of tillage and fertilization on biological nitrogen fixation and nutritional status of hairy vetch in a continuous cotton system

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Long‐term tillage and nitrogen fertilization in a continuous cotton–cover crop system influenced soil organic matter and nitrogen availability, shaping nitrogen acquisition strategies of a vetch cover crop. Conventional tillage promoted greater reliance on BNF, whereas no‐till systems favored soil‐derived nitrogen uptake and higher legume nitrogen ...

Agronomic performance, nitrogen fixation, and amino acid profile of different common bean genotypes in Germany

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Common beans (Phaseolus vulgaris L.) are a highly nutritious legume crop with global significance. However, their cultivation is limited in temperate regions like Germany due to climatic and agronomic constraints. The cultivation of beans has gained attention due to their potential contribution to climate change mitigation by reducing nitrogen

Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Potential Trophic Competition Between the European Perch Perca fluviatilis and Pikeperch Sander lucioperca

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...

Open‐Source Multinuclear Low‐Field Preclinical MRI Scanner

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
A step‐by‐step guideline for the construction of an open‐source multinuclear low‐field MRI scanner for preclinical studies is presented together with the first images acquired with the device. The scanner can detect 1H, 23Na, hyperpolarized 13C, and 15N signals at 66 mT. ABSTRACT Low‐field MRI (B0 ≤ 0.2 T) is emerging as a technology with the potential
