How has bird biodiversity changed over time? A review across spatio-temporal scales
Basic and Applied Ecology, 2023 Empirical quantification of biodiversity changes remains a challenge even in well surveyed groups such as birds. This may be because the change depends on spatio-temporal scales, specifically on spatial grain (i.e. average unit of area of the sampling or

Exposure to Selected Geogenic Trace Elements (I, Li, and Sr) from Drinking Water in Denmark
Geosciences, 2015 The naturally occurring geogenic elements iodine (I), lithium (Li), and strontium (Sr) have a beneficial effect on human health. Iodine has an essential role in human metabolism while Li and Sr are used, respectively, as a treatment for various mental ...

Long‐term temporal and spatial trends in eutrophication status of the Baltic Sea
Biological Reviews of The Cambridge Philosophical Society, 2017 Much of the Baltic Sea is currently classified as ‘affected by eutrophication’. The causes for this are twofold. First, current levels of nutrient inputs (nitrogen and phosphorus) from human activities exceed the natural processing capacity with an ...

Spatial and Temporal Trends of Perfluoroalkyl Substances in Global Ocean and Coastal Waters.
Environmental Science and Technology, 2021 Per- and polyfluoroalkyl substances (PFAS) have been widely detected in global surface waters since the early 2000s. Here, we have compiled and analyzed the published data for perfluorocarboxylates (PFCAs) and perfluorosulfonates (PFSAs) in surface ...

Graph WaveNet for Deep Spatial-Temporal Graph Modeling [PDF]
International Joint Conference on Artificial Intelligence, 2019 Spatial-temporal graph modeling is an important task to analyze the spatial relations and temporal trends of components in a system. Existing approaches mostly capture the spatial dependency on a fixed graph structure, assuming that the underlying ...
