Disjunct populations of European vascular plant species keep the same climatic niches
Aim Previous research on how climatic niches vary across species ranges has focused on a limited number of species, mostly invasive, and has not, to date, been very conclusive. Here we assess the d ...
Assessing sampling coverage of species distribution in biodiversity databases
Abstract Aim Biodiversity databases are valuable resources for understanding plant species distributions and dynamics, but they may insufficiently represent the actual geographic distribution and climatic niches of species. Here we propose and test a method to assess sampling coverage of species distribution in biodiversity databases in geographic and climatic space. Location Europe. Methods Using a test selection of 808,794 vegetation plots from the European Vegetation Archive (EVA), we assessed the sampling coverage of 564 European vascular plant species across both their geographic ranges and realized climatic niches. Range maps from the Chorological Database Halle (CDH) were used as bac…
Testing macroecological abundance patterns:the relationship between local abundance and range size, range position and climatic suitability among European vascular plants
Aim A fundamental question in macroecology centres around understanding the relationship between species' local abundance and their distribution in geographical and climatic space (i.e. the multi-dimensional climatic space or climatic niche). Here, we tested three macroecological hypotheses that link local abundance to the following range properties: (a) the abundance-range size relationship, (b) the abundance-range centre relationship and (c) the abundance-suitability relationship. Location Europe. Taxon Vascular plants. Methods Distribution range maps were extracted from the Chorological Database Halle to derive information on the range and niche sizes of 517 European vascular plant speci…
Local temperatures inferred from plant communities suggest strong spatial buffering of climate warming across Northern Europe
Recent studies from mountainous areas of small spatial extent (2500 km(2) ) suggest that fine-grained thermal variability over tens or hundreds of metres exceeds much of the climate warming expected for the coming decades. Such variability in temperature provides buffering to mitigate climate-change impacts. Is this local spatial buffering restricted to topographically complex terrains? To answer this, we here study fine-grained thermal variability across a 2500-km wide latitudinal gradient in Northern Europe encompassing a large array of topographic complexities. We first combined plant community data, Ellenberg temperature indicator values, locally measured temperatures (LmT) and globally…
Fremmede arter i Norge: resultater fra kvantitative økologiske risikovurderinger
1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in local biodiversity and ecosystem functioning, and, ultimately, to biotic homogenisation. 2. We risk-assessed all alien plants, animals, fungi and algae, within certain delimitations, that are known to reproduce in Norway. Mainland Norway and the Arctic archipelago of Svalbard plus Jan Mayen were treated as separate assessment areas. Assessments followed the Generic Ecological Impact Assessment of Alien Species (GEIAA) protocol, which uses a fully quantitative set of criteria.…
Matproduksjon, mattrygghet og miljø - innspill om kunnskapsbehov til gjennomføringen av det grønne skiftet - Uttalelse fra hovedkomiteen i Vitenskapskomiteen for mat og miljø (VKM)
Denne rapporten er utarbeidet av Vitenskapskomiteen for mat og miljø (VKM), en uavhengig, tverrfaglig komité som utarbeider kunnskapsgrunnlag for den norske mat- og miljøforvaltningen på områdene matproduksjon, mattrygghet og biologisk mangfold. De siste tiårene har FNs klimapanel, Det internasjonale naturpanelet, Det internasjonale ressurspanelet og flere andre paneler og organisasjoner levert rapporter som dokumenterer at befolkningsvekst og menneskelig aktivitet fører med seg store og økende utfordringer på miljø-, klima- og ressursområdet. Endringer innen disse områdene påvirker matproduksjon, matsikkerhet, mattrygghet, folkehelse og naturverdier i alle deler av verden (UNEP, 2021). Sam…
Food and chemical substances relevant for monitoring
At request from the Norwegian Food Safety Authority (NFSA), VKM has identified food groups and food items consumed by the Norwegian population that are relevant for monitoring regarding content of one or more undesirable chemical substances (Figure 1). Undesirable chemical substances were defined as chemical substances in food that may constitute a potential health risk. Paid open access

The many ways topography buffers responses to climate change
During climate change, populations have two survival options - they can remain in situ and tolerate the new climatic conditions ('stay'), or they can migrate to track their climatic niches elsewhere ('go'). Staying requires broad climatic tolerances, niche shifts due to changing biotic interactions, acclimation through plasticity, or rapid genetic adaptation. Going, in contrast, requires good dispersal and colonization capacities. However, both the magnitude of climate change experienced locally and the capacities required for staying or going in response to climate change are not constant across landscapes, but affected by local microclimatic variation associated with topographic complexit…
