The impact of land use- and climate change on the managed eco-geomorphic balance in the Alps [PDF]

, 2015
During the last decades, agricultural development in European mountain regions has caused considerable changes in land use intensity and management and as a consequence, in land cover (Brugger et al. 1984; MacDonald et al., 2000; Bätzing, 2005).

Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

Journal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Treeless vegetation of the Australian Alps [PDF]

, 2013
Based on 1222 floristic quadrat samples, 56 plant communities were identified in treeless vegetation in the Australian Alps of south-eastern Australia. (c. 35º 30´–38ºS, 146°–149°E). The study encompassed vegetation from above the upper limit of trees on

Traditional versus sprinkler irrigation of mountain hay meadows in the Valais : consequences for biodiversity [PDF]

, 2015
Semi-natural grasslands including hay meadows belong to the most species-rich habitats in central Europe and are therefore of high conservation value. The high biodiversity of these grasslands has been maintained for many centuries through the regular ...

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Forest Conversion Reduces Soil Water Retention in Tropical Rainforest

Land Degradation &Development, EarlyView.
ABSTRACT Extensive primary forests are being converted to secondary forests and plantations owing to human activities in recent decades, which have substantial effects on soil hydrological processes. However, the potential impact of forest conversion on soil water retention remains poorly understood.

Species‐Specific Shrub Encroachment Drives Divergent Soil Fungal Assembly Processes and Network Structures in Alpine Meadows

Land Degradation &Development, EarlyView.
ABSTRACT Shrub encroachment is rapidly transforming alpine meadow ecosystems worldwide, yet its consequences for belowground microbial organization remain insufficiently understood, particularly when different shrub species exert contrasting ecological effects.

Short-term grazing exclusion has no impact on soil properties and nutrients of degraded alpine grassland in Tibet, China [PDF]

Solid Earth, 2015
Since the 1980s, alpine grasslands have been seriously degraded on the Tibetan Plateau. Grazing exclusion by fencing has been widely adopted to restore degraded grasslands.

Asymmetric Response of Soil Heterotrophic Respiration and Its Temperature Sensitivity in a Desert Steppe Under Climate Change

Land Degradation &Development, EarlyView.
ABSTRACT Soil heterotrophic respiration (Rh) and its temperature sensitivity (Q10) are important variables reflecting the intensity of feedback between the grassland carbon cycle and climate change. However, the factors regulating Rh and Q10 in desert grasslands under climate change remain unclear, and the asymmetric response of Rh during warming and ...
