Summary The ongoing changes to climate challenge the conservation of forest biodiversity. Yet, in thermally limited systems, such as temperate forests, not all species groups might be affected negatively. Furthermore, simultaneous disturbance regime have potential mitigate climate‐related impacts on species. Here, we (i) investigated long‐term effect change biodiversity a mountain landscape, (ii) assessed effects different frequencies, severities and sizes (iii) identified hotspots at...
Abstract. Karst systems are important for drinking water supply. Future climate projections indicate increasing temperature and a higher frequency of strong weather events. Both will influence the availability quality provided from karst regions. Forest disturbances such as windthrow can disrupt ecosystem cycles cause pronounced nutrient losses ecosystems. In this study, we consider time period before after wind disturbance (2007/08) to identify impacts on DIN (dissolved inorganic nitrogen)...
Varying altitudes and aspects within small distances are typically found in mountainous areas. Such a complex topography complicates the accurate quantification of forest C dynamics at larger scales. We determined effects altitude aspect on cycling typical, catchment Northern Limestone Alps. Forest pools fluxes were measured along two altitudinal gradients (650–900 m a.s.l.) south-west (SW) north-east (NE) facing slopes. Net ecosystem production (NEP) was estimated using biometric approach...
Anthropogenic emissions of nitrogen (N) and sulphur (S) compounds their long-range transport have caused widespread negative impacts on different ecosystems. Critical loads (CLs) are deposition thresholds used to describe the sensitivity ecosystems atmospheric deposition. The CL methodology has been a key science-based tool for assessing environmental consequences air pollution. We computed CLs eutrophication acidification using European long-term dataset intensively studied forested...
Abstract. Seven long-term observation sites have been established in six regions across Austria, covering major ecosystem types such as forests, grasslands, and wetlands a wide bioclimatic range. The purpose of these observations is to measure key parameters serving baselines for assessing the impacts extreme climate events on carbon cycle. datasets collected include meteorological variables, soil microclimate, CO2 fluxes, tree stem growth, all recorded at high temporal resolution (15–60...
Protected Areas are a key component of nature conservation. They can play an important role in counterbalancing the impacts ecosystem degradation. For optimal protection Area it is essential to account for variables underlying major Ecosystem Services area delivers, and threats upon them. Here we show that perception these differs markedly between scientists managers mountains transitional waters. Scientists emphasise abiotic biotic nature, whereas highlight socio-economic, cultural...
The contribution of forest understory to the temperate carbon sink is not well known, increasing uncertainty in C cycling feedbacks on global climate as estimated by Earth System Models.
Abstract The productivity of tropical forests is driven by climate (precipitation, temperature, and light) soil fertility (geology topography). While large‐scale drivers are well established, knowledge on the sensitivity lowland net primary production to anomalies remains scarce. We here analyze seven consecutive years monthly recorded forest aboveground (ANPP) in response a recent El Niño–Southern Oscillation (ENSO) anomaly. ENSO transition period resulted increased temperatures decreased...
Slow or failed tree regeneration after forest disturbance is increasingly observed in the central European Alps, potentially amplifying carbon (C) loss from disturbance. We aimed at quantifying C dynamics of a poorly regenerating site with special focus on role non-woody ground vegetation.Soil CO2 efflux, fine root biomass, vegetation increment and litter input were assessed (i) an undisturbed section ~ 110 years old Norway spruce stand, (ii) disturbed which was clear-cut six ago (no...
Abstract. Information about forest background reflectance is needed for accurate biophysical parameter retrieval from canopies (overstory) with remote sensing. Separating under- and overstory signals would enable more modeling of carbon energy fluxes. We retrieved values the normalized difference vegetation index (NDVI) understory multi-angular Moderate Resolution Imaging Spectroradiometer (MODIS) bidirectional distribution function (BRDF)/albedo data (gridded 500 m daily Collection 6...

Climate change and excess deposition of airborne nitrogen (N) are among the main stressors to floristic biodiversity. One particular concern is deterioration valuable habitats such as those protected under European Habitat Directive. In future, climate-driven shifts (and losses) in species potential distribution, but also N driven nutrient enrichment may threaten these habitats. We applied a dynamic geochemical soil model (VSD+) together with novel niche-based plant response (PROPS) 5 forest...
Assessments of synergies and trade-offs between climate change mitigation forest biodiversity conservation have focused on set-aside areas. We evaluated a more comprehensive portfolio silvicultural management adaptations to measures exemplary for managed European beech forests. Based the available literature, we assessed range common their effects carbon sequestration in wood products substituting carbon-intensive products. complemented this review with simulations typical mountainous region...
Excess nitrogen (N) deposition and gaseous N emissions from industrial, domestic, agricultural sources have led to increased nitrate leaching, the loss of biological diversity, has affected carbon (C) sequestration in forest ecosystems. Nitrate leaching affects purity karst water resources, which contribute around 50% Austria’s drinking supply. Here we present an evaluation drivers dissolved inorganic (DIN) concentrations fluxes a catchment Austrian Alps (LTER Zöbelboden) 27 years records....
