Transparent Exopolymer Particles (TEP), phytoplankton and picocyanobacteria a littoral-to-pelagic depth-gradient in a large subalpine lake

Journal of Limnology, 2021
Transparent Exopolymer Particles (TEP) play an important role in the organic carbon cycle of many aquatic systems but the production and distribution of TEP have been studied mainly in the marine environment, neglecting the large oligotrophic lakes.

Assessment of the adaptive reserve in children with sarcopenia based on the activity level of regulatory systems

Zdorovʹe Rebenka
Background. Sarcopenia, commonly linked with ­aging, has recently been observed in children, affecting 5–40 % of the pediatric population. Loss of muscle mass in childhood limits physical performance and increases the risk of injuries and metabolic ...

Spatial-temporal study of cluster 5 picocyanobacteria and exopolymeric microgels in Lake Maggiore

Advances in Oceanography and Limnology, 2022
In the oligotrophic Lake Maggiore, the majority of picocyanobacteria are phycoerythrin-bearing Synechococcus-type belonging to cluster 5 (Pcy-5). Their distribution was followed in a seven-year study along a depth gradient from the surface down to 350 m

Environmental factors as drivers for macroinvertebrate and diatom diversity in Alpine lakes: New insights from the Stelvio National Park (Italy)

Journal of Limnology, 2019
Information on the biodiversity of high altitude lakes in the Stelvio National Park was scarce and fragmentary, in most cases limited to a few studies on a single biological issue. To fill this gap, a multidisciplinary research program was established in

Asymmetric Dual‐Electron Bridge Via Gradient Orbital Coupling for Robust Alkaline Oxygen Evolution in Low‐Iridium Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The engineered IrOx/FeEu‐NiTex composite, with ultralow Eu (0.72 at%) and Ir (0.14 at%) content, harnesses an asymmetric dual‐electron‐bridge structure (Ni 3d–O 2p–Eu 4f, Ni 3d–O 2p–Ir 5d) for gradient orbital coupling. This unique architecture delivers superior and robust alkaline oxygen evolution activity, enabling efficient low‐iridium water ...
