Land Degradation &Development, EarlyView.ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Land Degradation &Development, EarlyView.ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

Limnology and Oceanography: Methods, EarlyView.Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Limnology and Oceanography: Methods, EarlyView.Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.
