Digital technology is changing nature conservation in increasingly profound ways. We describe this impact and its significance through the concept of 'digital conservation', which we found to comprise five pivotal dimensions: data on nature, people, integration analysis, communication experience, participatory governance. Examining digital innovation addressing how development, implementation diffusion may be steered, warn against hypes, techno-fix thinking, good news narratives unverified...
Range expansion and increasing densities of large herbivores are held responsible for large‐scale habitat degradation in a wide range natural semi‐natural ecosystems. Herbivore‐driven ecosystem changes frequently represent predictable transitions from one vegetation state to another. Whether such justify the value judgement ‘habitat degradation’ may be debatable as this strongly depends on individual perspective. To further debate herbivore‐driven degradation, I apply concept alternative...
Abstract Aim We used a landscape‐scale study of birch invasion onto heather moorland to determine the consistency changes in vegetation type and soil properties community composition five organism groups. Our aim was whether degree which organisms respond natural and/or induced (e.g. land‐use climate) habitat is consistent across trophic taxonomic groups context conservation policies for woodland moorland. Location Mainland Scotland. Methods sampled mesostigmatid mites, oribatid fungi,...
We tested the hypothesis that large herbivores manipulate their own food supply by modifying soil nutrient availability. This was investigated experimentally impact of faeces on grasses, mosses and biological properties in tundra ecosystems. For this, we increased density reindeer Rangifer tarandus platyrhynchus studied response a system Spitsbergen to this single faecal addition treatment for four subsequent years. From third year onwards had unambiguously enhanced standing crop as...
Summary Large herbivores have significant impacts on the structure and function of temperate tropical ecosystems. Yet herbivore arctic systems, particularly mechanisms by which they influence plant communities, are largely unknown. High vegetation, commonly overlying permafrost soils, is often moss‐dominated with sparse vascular cover. We investigated potential large communities via their impact depth moss layer, leading to warmer soils potentially benefiting plants. found that grazer depth,...
The cumulative effects of climate warming on herbivore vital rates and population dynamics are hard to predict, given that the expected differ between seasons. In Arctic, warmer summers enhance plant growth which should lead heavier more fertile individuals in autumn. Conversely, warm spells winter with rainfall (rain-on-snow) can cause 'icing', restricting access forage, resulting starvation, lower survival fecundity. As body condition is a 'barometer' energy demands relative intake, we...
Background “The enigma of soil animal species diversity” was the title a popular article by J. M. Anderson published in 1975. In that paper, provided insights on great richness found soils, but emphasized mechanisms contributing to high belowground were largely unknown. Yet, exploration driving has focused, almost exclusively, above-ground plant and communities, nearly 35 years later we have several new hypotheses are not much closer revealing why soils so rich species. One persistent...
The Arctic is viewed as most sensitive to climate warming and subject a general greening. Yet, summer weather conditions, which differ greatly among years, are believed have little direct effect on arctic plant productivity. dominant view that between‐year variation in aboveground biomass small poorly related conditions the same year Arctic. Here, we test this based 12‐year investigation of peak habitats, functional types, species high‐arctic Svalbard. Our study revealed twofold (range 23–46...
The availability of affordable 'recreational' camera traps has dramatically increased over the last decade. We present survey results which show that many conservation practitioners use cheaper units for research rather than more expensive 'professional' equipment. our perspective using two popular models trap ecological field-based studies. used (for >2 years) presented us with a range practical problems at all stages their including deployment, operation, and data management, collectively...
Abstract The rapid rise of citizen science, with lay people forming often extensive biodiversity sensor networks, is seen as a solution to the mismatch between data demand and supply while simultaneously engaging citizens environmental topics. However, science recording schemes require careful consideration how motivate, train, retain volunteers. We evaluated novel computing framework that allowed for automated generation feedback scientists using natural language (NLG) technology. worked...
According to classical exploitation theory, an increase of primary productivity should result in increased herbivore grazing pressure, thus maintaining a low plant standing crop. However, field data obtained from salt marsh revealed maximal pressure by hares, rabbits, and geese at intermediate levels Grazing was relatively the more productive parts. We argue that this pattern is due foraging efficiency these herbivores dense vegetation. In order investigate hypothesis, we examine...
Summary 1 The effects of resource competition and herbivory on a target species, Triglochin maritima , were studied along productivity gradient vegetation biomass in temperate salt marsh. 2 Transplants used to measure the impact grazing, soil fertility over two growing seasons. Three parts marsh selected represent different successional stages; reached local dominance at intermediate salt‐marsh vegetation. At each stage, three treatments (full plant competition, root only, no competition)...
• The effects of nitrogen (N) deposition on the moss Racomitrium lanuginosum within montane heath in Scotland were investigated over 5 yr. Permanent field plots sprayed with KNO3 or NH4Cl solutions, at doses equivalent to 10 and 40 kg N ha−1 yr−1, 3–6 applications each summer. growth cover severely reduced by addition, whilst proportion dead shoots greatly increased. dose decreased inducibility shoot nitrate reductase activity (NRA), suggesting that saturation occurred, caused an increase...
Abstract Increased atmospheric nitrogen (N) deposition has been held responsible for the large‐scale invasion of graminoids (grasses, sedges and rushes) in a wide range habitats from forests to upland heaths, causing dramatic changes plant species composition. Concurrently with an increase N over last century, livestock grazing intensified many parts world following policy reform, leading degradation natural seminatural ecosystems. On basis series experiments conducted Scottish montane...
Mosses are one of the most diverse and widespread groups plants often form dominant vegetation in montane, boreal arctic ecosystems. However, unlike higher plants, mosses lack developed root vascular systems, which is thought to limit their access soil nutrients. Here, we test ability two physiologically taxonomically distinct moss species take up soil- wet deposition-derived nitrogen (N) natural intact turfs using stable isotopic techniques ( 15 N). Both exhibited increased concentrations...
