Small‐Scale Topographic Variability Shapes Molecular Diversity of Organic Matter in Coastal Dune Soils

Journal of Plant Nutrition and Soil Science, EarlyView.
Topography shapes ecosystem controls, driving microclimate, hydrology, and vegetation, which, in turn, influence topsoil traits and DOM composition in coastal dune soils. Distinct molecular patterns emerge across north‐facing and south‐facing slopes and dune valleys.

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Synergistic integration of vision transformers and advanced segmentation algorithms for panoptic mapping of marine litter

Frontiers in Marine Science
Marine litter is composed of various types of debris and poses a significant risk to marine ecosystems, biodiversity, and human life. Effective management and mitigation measures of marine litter, otherwise known as marine waste, can only be achieved ...

Synergistic and Trade‐Off Effects of Plant Communities on Slope Runoff and Sediment Yield

Land Degradation &Development, EarlyView.
ABSTRACT Plant community functional structure plays an important role in regulating slope runoff and sediment yield on the Loess Plateau. Based on runoff plot monitoring and vegetation surveys in the Yangjuangou catchment, we used partial least squares regression (PLSR) and variable importance in projection (VIP) analysis to assess the effects of ...

Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

Limnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

Nautical Tourism Vessels as a Source of Seafloor Litter: An ROV Survey in the North Adriatic Sea

Journal of Marine Science and Engineering
Marine litter threatens ocean ecosystems, and nautical tourism, as a source of litter, contributes significantly. This paper presents a qualitative and quantitative study of seafloor litter in the Bay of Selehovica in the northern Adriatic Sea.
