Atmospheric nitrogen (N) deposition is a recognized threat to plant diversity in temperate and northern parts of Europe North America. This paper assesses evidence from field experiments for N effects thresholds terrestrial protection across latitudinal range main categories ecosystems, arctic boreal systems tropical forests. Current thinking on the mechanisms diversity, global distribution G200 ecoregions, current future (2030) estimates atmospheric N-deposition rates are then used identify...
Climatic changes, including altered precipitation regimes, will affect key ecosystem processes, such as plant productivity and biodiversity for many terrestrial ecosystems. Past ongoing experiments have been conducted to quantify these potential changes. An analysis of indicates that they provided important information on how water regulates processes. However, do not adequately represent global biomes nor forecasted scenarios their contribution advance our understanding responses changes is...
Human activity in the last century has led to a significant increase nitrogen (N) emissions and atmospheric deposition. This N deposition reached level that caused or is likely cause alterations structure function of many ecosystems across United States. One approach for quantifying pollution would be harmful determination critical loads. A load defined as input pollutant below which no detrimental ecological effects occur over long-term according present knowledge. The objectives this...
Significance One of the greatest challenges in projecting future shifts global climate is understanding how soil respiration rates will change with warming. Multiple experimental warming studies have explored this response, but no consensus has been reached. Based on a synthesis 27 spanning nine biomes, we find that although increases rates, there limited evidence for shifting response We also note universal decline temperature sensitivity at temperatures >25 °C. Together, our data...
Abstract Atmospheric nitrogen ( N ) deposition is a global and increasing threat to biodiversity ecosystem function. Much of our current understanding impacts comes from field manipulation studies, although interpretation may need caution where simulations (in terms dose, application rate form) have limited realism. Here, we review responses simulated the UKREATE network, group nine experimental sites across UK in diversity heathland, grassland, bog dune ecosystems which include studies with...
Abstract Interactive effects of multiple global change factors on ecosystem processes are complex. It is relatively expensive to explore those interactions in manipulative experiments. We conducted a modeling analysis identify potentially important and stimulate hypothesis formulation for experimental research. Four models were used quantify interactive climate warming ( T ), altered precipitation amounts [doubled (DP) halved (HP)] seasonality (SP, moving July August January February create...
Accurate quantification of biodiversity is fundamental to understanding ecosystem function and for environmental assessment. Molecular methods using DNA (eDNA) offer a non-invasive, rapid, cost-effective alternative traditional assessments, which require high levels expertise. While eDNA analyses are increasingly being utilized, there remains considerable uncertainty regarding the dynamics multispecies eDNA, especially in variable systems such as rivers. Here, we utilize four sets upland...
There is growing interest in the role that natural capital plays underpinning ecosystem services. Yet, there remain differences and inconsistencies conceptualisation of services humans play their delivery. Using worked examples a stocks flows systems approach, we show both (NC) human-derived (produced, human, social, cultural, financial) (HDC) are necessary to create at many levels. HDC three stages service Firstly, as essential elements combined social-ecological system potential service....
Ecosystem services modelling tools can help land managers and policy makers evaluate the impacts of alternative management options or changes in use on delivery ecosystem services. As variety complexity these increases, there is a need for comparative studies across range settings, allowing users to make an informed choice. Using examples provisioning regulating (water supply, carbon storage nutrient retention), we compare three spatially explicit – LUCI (Land Utilisation Capability...
Abstract We used a nonintrusive field experiment carried out at six sites – Wales (UK), Denmark (DK), the Netherlands (NL), Hungary (HU), Sardinia (Italy IT), and Catalonia (Spain SP) along climatic latitudinal gradient to examine response of plant species richness primary productivity warming drought in shrubland ecosystems. The treatment raised plot daily temperature by ca. 1 °C, while led reduction soil moisture peak growing season that ranged from 26% SP site 82% NL site. During 7 years...
Abstract Polycyclic aromatic hydrocarbons ( PAH s) in the environment originate mainly from incomplete combustion of fossil fuels, and pose a significant human health risk. Soils act as environmental sinks for s, they become strongly absorbed onto soil particles; degradation is driven by microbial catabolism, although it dependent on bioavailability. There current interest burying biochar long‐term carbon store; however, inherently contains varying levels s its application could contaminate...
