Nitrogen dynamics in low-arctic streams are linked to terrestrial vegetation cover
Arctic ScienceThe Arctic is experiencing rapid climatic changes, leading to landscape shifts, including increased vegetation cover (greening) and altered nutrient dynamics.

, 2021 Arroyos y paisaje no parecen ser temas compatibles en el Área Metropolitana de Buenos Aires (AMBA). Lo metropolitano nos remite a lo urbano, a lo construido, a una naturaleza artificial creada para cubrir las necesidades de la ciudad, así como pensar en ...

Limnology and Oceanography: Methods, EarlyView.Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Limnology and Oceanography: Methods, EarlyView.Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing
Limnology and Oceanography: Methods, EarlyView.Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

GEOMORPHOLOGIC ANALYSIS OF DRAINAGE NETWORKS ON MARS [PDF]
Acta Geographica Debrecina. Landscape & Environment Series, 2012 Altogether 327 valleys and their 314 cross-sectional profiles were analyzed on Mars, including width, depth, length, eroded volume, drainage and spatial density, as well as the network structure.According to this systematic analysis, five possible ...

Limnology and Oceanography: Methods, EarlyView.Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.

Long‐Term Morphodynamic Responses to Flood Diversion in the Lower Kano River, Japan
River Research and Applications, EarlyView.ABSTRACT Fluvial morphodynamics—the interaction between water flow, sediment transport, and channel morphology—is a central concern in sustainable river management. However, the long‐term effects of flood diversion remain underexplored. This study investigated the decadal‐scale morphodynamic responses of the lower Kano River in Japan following the ...
