Sub-landscape (locality level) characteristics of forest cover formation in Vodlozersky National Park

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017
The results of studies on the sub-landscape structure of forests in the Karelian part of the Vodlozersky national park are presented. Seven types of geographical localities (local landscape) were identified, their digital map was produced ...

A talus rock glacier in Nantlle Valley, North Wales

Journal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Asymmetric Responses of Ecosystem Health to Urbanization in a Typical Karst City: Spatiotemporal Patterns and Driving Mechanisms in Guilin, China

Land Degradation &Development, EarlyView.
ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important for regional sustainability.

Estimation Accuracy Obviously Increased of Soil Organic Carbon Content Based on Habitat Patches Scale Using Interpretable Machine Learning in Southwest China

Land Degradation &Development, EarlyView.
ABSTRACT Although machine learning models have been successfully applied to estimate soil organic carbon (SOC), the lack of interpretability research has resulted in the absence of mechanistic explanations for these models. Therefore, in this study, we adopted the following workflow: first, we divided the whole study area into several subregions using ...

« Relief » et « montagne » : les enseignants de l’école élémentaire confrontés à la mise en mots et en images de la saillance

Revue de Géographie Alpine, 2016
In this paper my goal is to indicate how children’s geographies of the alpine mountain resonate with academic knowledge about the mountain. The aim is to show how teachers of primary school students (aged 6 to 11) use the words “relief” and “mountain ...

Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

Effects of Composite Reclamation Models of Sea Buckthorn, A Pioneer Species in Semi‐Arid Regions, on Soil Quality and Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Open‐pit coal mining severely degrades soil and ecosystem functions, constraining regional sustainability. Vegetation‐based reclamation has therefore been widely adopted as an effective approach to promote soil recovery and ecosystem restoration.

Designing for biodiversity data in place: Species, encounters, and interfaces

People and Nature, EarlyView.
Abstract Species occurrence data, which records the presence of an organism at a point in space and time, is central to environmental science and its opening up to new forms of participation such as citizen science. Such data are increasingly aggregated and mobilised, reaching diverse audiences.
