Field assessment of nitrogen sources in Brassica carinata using physiological indicators of nitrogen status under temperate no‐till conditions

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Improving nitrogen (N) use efficiency in Brassica carinata is essential to sustain yield and lower biofuel carbon intensity under variable field conditions. We hypothesized that integrating physiological indicators, such as the nitrogen nutrition index (NNI) and the critical nitrogen uptake curve (CriNUC), into N management frameworks would ...

Branchial localization of acid (A‐type) and base (B‐type) excreting ionocytes in Amazonian stenohaline freshwater Potamotrygon ray

Journal of Fish Biology, Volume 108, Issue 3, Page 922-931, March 2026.
Abstract The branchial epithelium of Potamotrygon—a member of the only strictly freshwater elasmobranch family Potamotrygonidae—was observed via immunohistochemistry, and two distinct forms of ionocytes were identified. The acid (A‐type) and base (B‐type) secreting cells with respective basolateral–apical localizations of Na+/K+‐ATPase–Na+/H+ exchanger

Decarboxylation mechanisms of C4 photosynthesis in Saccharum spp.: increased PEPCK activity under water-limiting conditions

BMC Plant Biology, 2019
Background C4 plants have been classified into three subtypes based on the enzymes used to decarboxylate C4 acids in the bundle sheath cells (NADP-ME, NAD-ME and PEPCK pathways).

Dynamic Models Assessing Different Laboratory Conditions for the Cultivation of Giant Barnacle (Austromegabalanus psittacus) Larvae

Aquaculture Research, Volume 2026, Issue 1, 2026.
Barnacle aquaculture is a developing area of production that is currently limited by the reliance on capturing naturally produced larvae. The solution to this limitation would be the development of hatcheries for culturing barnacle larvae and juveniles (Juvs).

Combined effect of green-colored covers and shading on the growth of sisal (Furcraea hexapetala) plants

Agronomía Colombiana, 2017
Plants have the ability to respond in different ways to the quality of light, its intensity, and the combination of both. In addition, chlorophyll absorbs light in the blue and red bands of the spectrum, but green and infrared light are poorly absorbed ...
