The paleoclimate during the Early Eocene in Maritime Antarctica is characterized by cool conditions without a pronounced dry season. Soils formed on volcanic material under such climate conditions in modern analogue environments are usually Andosols rich in nanocrystalline minerals without pedogenic smectite. The paleosols formed on volcanic materi...

We measure the age of soil organic matter (SOM) in soil depth profiles using fallout radionuclide (FRN) chronometry. The FRN age model quantifies the well-known lag in ∆14C which is the time between biological carbon fixation and its incorpration into SOM 1–3. The FRN model also reveals sharp excursions in ∆14C at depth to extremely old ages, which...

A dense concentration of old‐growth forest and a wet, cold climate promote mineral weathering and leaching in coastal temperate rainforest soils. Our objective was to assess soil development and soil organic carbon (SOC) distribution across 18 soil profiles in remote, upland terrain of southeast Alaska where pedon data are sparse. We made soil morp...

Quantifying soil redistribution rates, including both erosion and deposition, is critical for understanding erosion processes, landscape evolution, land management strategies, and the carbon cycle. In the Northeast Pacific coastal temperate rainforest, the interaction of perhumid climate and dense coniferous forest tends to form Spodosols which are...

Nonmarine rocks in sea cliffs of southern California store a detailed record of weathering under tropical conditions millions of years ago, where today the climate is much drier and cooler. This work examines early Eocene (~ 50-55 million-year-old) deeply weathered paleosols (ancient, buried soils) exposed in marine terraces of northern San Diego C...

The present-day semiarid region of NE Brazil experienced multiple periods of increased precipitation during the Quaternary. They were likely linked to global-scale events (e.g., Heinrich Events) and drove changes in vegetation dynamics, leading to the expansion of rainforest vegetation. Here, we hypothesize that soil features preserved in cave sedi...

Quantifying soil redistribution rates, including both erosion and deposition, is critical for insights into erosion processes, landscape evolution, land management strategies, and the carbon cycle. While previous soil redistribution studies have largely focused on the effects of climate, topography, vegetation, and time, only a few studies have inv...

The interaction of similar soil forming factors with different parent materials determines soil chemical weathering, influencing soil processes and properties. In the coastal temperate rainforests of southeast Alaska, Spodosols is the dominant soil order in well-drained parent materials regardless of the lithology. Yet, the role of lithology on che...

Compared to the 1970s, the edge of the Ecology Glacier on King George Island, maritime Antarctica, is positioned more than 500 m inwards, exposing a large area of new terrain to soil-forming processes and periglacial climate for more than 40 years. To gain information on the state of soil formation and its interplay with microbial activity, three h...

To gain a better understanding of the global application of soil erosion prediction models, we comprehensively reviewed relevant peer-reviewed research literature on soil-erosion modelling published between 1994 and 2017. We aimed to identify (i) the processes and models most frequently addressed in the literature, (ii) the regions within which mod...

Soil erosion can present a major threat to agriculture due to loss of soil, nutrients, and organic carbon. Therefore, soil erosion modelling is one of the steps used to plan suitable soil protection measures and detect erosion hotspots. A bibliometric analysis of this topic can reveal research patterns and soil erosion modelling characteristics tha...

The quantification of soil redistribution rates (erosion and deposition) has been crucial for understanding erosion processes and landscape evolution in natural areas worldwide. Soil redistribution assessments have mostly focused on the effect of topography, climate, and vegetation, but few explored how soil development influences soil redistributi...

The perhumid climate of the coastal temperate rainforest in SE Alaska favors high rates of mineral weathering and soil formation. The rapid melting of mountain glaciers of the region exposes vast areas of bedrock to chemical weathering and soil formation. However, little is known about the soil mineral transformation in the region. In this study, w...

Systematic bibliometric investigations are useful to evaluate and compare the scientific impact of journal papers, book chapters and conference proceedings. Such studies allow the detection of emerging research topics, the analyses of cooperation networks, and the collection of in-depth insights into a specific research topic. In the presented work...

The objective of this study was to determine if the Early Eocene paleosols on King George Island, Maritime Antarctica, have acquired their reddish color during the paleopedogenesis, by burial diagenesis and/or by heating of a covering lava flow. We used micromorphology, diffuse reflectance spectroscopy, X-ray diffraction, and mineral magnetic prope...

We investigated the origin of reddish layers between basalt flows in an Early Eocene volcanic succession in King George Island, Maritime Antarctica. Previous studies in the area classified these layers as regolith surfaces, baked zones and paleosols, but the properties of these layers and the reasons for their classification are not clarified. Sinc...

One of the challenges of digital cartography is the complete automation of generalization. However, there is no convergence in the literature about this possibility. The aim of this work was to generalize using semi-automatic techniques a land cover map in the original scale 1:20.000 to 1:50.000 in raster format. We tested two scenarios, using six...

We used the Ripley's K function to describe the spatial dynamics of chestnut blight (Cryphonectria parasitica (Murrill) Barr) in sweet chestnut orchards to look at pattern in the pathogen distribution over time and the effect of the location of infected trees on the pattern of disease spread. We used data on infected and dead trees in 2003, 2004, 2...
