Densely populated coastal zones are significantly impacted by anthropogenic pressures, particularly urbanized semi‐enclosed bays with long residence times of waters and nutrients. Eutrophication is a primary issue resulting from human settlement in coastal zone, as it drastically modifies the structure of biological communities, particularly the phytoplankton. The aim of this study is to assess whether eutrophication functions...
Despite deep learning being state of the art for data‐driven model predictions, its application in ecology is currently subject to two important constraints: (i) deep‐learning methods are powerful in data‐rich regimes, but in ecology data are typically sparse; and (ii) deep‐learning models are black‐box methods and inferring the processes they represent are non‐trivial to elicit. Process‐based (= mechanistic) models are not co...
Distance decay 2.0 – A global synthesis of taxonomic and functional turnover in ecological communitiesNARA Subscribed
Aim Understanding the variation in community composition and species abundances (i.e., β‐diversity) is at the heart of community ecology. A common approach to examine β‐diversity is to evaluate directional variation in community composition by measuring the decay in the similarity among pairs of communities along spatial or environmental distance. We provide the first global synthesis of taxonomic and functional distance decay...
High‐throughput Plasmodium genomic data is increasingly useful in assessing prevalence of clinically important mutations and malaria transmission patterns. Understanding parasite diversity is important for identification of specific human or parasite populations that can be targeted by control programmes, and to monitor the spread of mutations associated with drug resistance. An up‐to‐date understanding of regional parasite po...
Soil nitrogen (N) availability is critical for grassland functioning. However, human activities have increased the supply of biologically limiting nutrients, and changed the density and identity of mammalian herbivores. These anthropogenic changes may alter net soil N mineralization (soil net N min ), that is, the net balance between N mineralization and immobilization, which could severely impact grassland structure and funct...
The Global Naturalized Alien Flora (Glo NAF ) databaseNARA Subscribed
This dataset provides the Global Naturalized Alien Flora (Glo NAF ) database, version 1.2. Glo NAF represents a data compendium on the occurrence and identity of naturalized alien vascular plant taxa across geographic regions (e.g. countries, states, provinces, districts, islands) around the globe. The dataset includes 13,939 taxa and covers 1,029 regions (including 381 islands). The dataset is based on 210 data sources. For e...
Asexual taxa often have larger ranges than their sexual progenitors, particularly in areas affected by Pleistocene glaciations. The reasons given for this ‘geographical parthenogenesis’ are contentious, with expansion of the ecological niche or colonisation advantages of uniparental reproduction assumed most important in case of plants. Here, we parameterized a spread model for the alpine buttercup Ranunculus kuepferi and reco...
A matter of scale: apparent niche differentiation of diploid and tetraploid plants may depend on extent and grain of analysisNARA Subscribed
Aim Emerging polyploids may depend on environmental niche shifts for successful establishment. Using the alpine plant Ranunculus kuepferi as a model system, we explore the niche shift hypothesis at different spatial resolutions and in contrasting parts of the species range. Location European Alps. Methods We sampled 12 individuals from each of 102 populations of R. kuepferi across the Alps, determined their ploidy levels, deri...
Recent changes in production in oligotrophic Uinta Mountain lakes, Utah, identified using paleolimnologyNARA Subscribed
We use multiple proxies from lake sediment records of six remote alpine lakes in the Uinta Mountains, Utah, to investigate primary production and potential drivers of changes in trophic status over the last two centuries. Chlorophyll a, chlorophyll a flux, and percentage of organic matter (determined by loss on ignition) increase beginning in the mid‐20th century in five of the six alpine study lakes, indicating increasing pro...
Aim To evaluate the effect of post‐glacial migration lags on the current distribution of Alpine plants and the factors responsible for possible range‐filling differences among species. Location Austrian Alps. Methods We used species distribution models to predict environmentally suitable sites for 183 Alpine plants at a fine spatial resolution (100 × 100 m 2 ). We overlaid these predictions with independent mapping data (3′× 5...
