“…Temperature and spatial connectivity were identified in the special issue as two main factors that constrain Arctic freshwater α diversity (see Laske et al., 2022; Lento, Culp et al., 2022; Schartau et al., 2022), and our broad‐scale multi‐organism assessment of average standardised diversity corroborated these findings (Figure 2). Low diversity was observed in cold regions at high latitudes and high elevations and where there are barriers to dispersal (on islands and around mountain ranges).…”

“…In circumpolar assessments, α diversity was lowest at the highest latitudes for benthic diatoms (Kahlert et al., 2022), plankton (Schartau et al., 2022), benthic macroinvertebrates (Lento, Culp et al., 2022), and fish (Laske et al., 2022), and showed general declines with increasing latitudes. This latitudinal decline was strongest and most consistent for benthic macroinvertebrates, both at circumpolar and regional scales (Lento, Culp et al., 2022; Lento, Laske et al., 2022). Hotspots for biodiversity varied among taxonomic groups, but commonly included Fennoscandia, low‐latitude and low‐altitude regions of Canada, and coastal regions of Alaska.…”

“…These results are not necessarily contradictory, but are likely to be a consequence of the combined effects of differences in spatial scales of the studies and region‐specific conditions. Warming has not been uniform across the Arctic regions (Hansen et al., 1999) and responses to warming will therefore differ among regions (Lento, Culp et al., 2022, but see also Taylor et al., 2020). Such heterogeneity in responses underscores the need for both regional and circumpolar assessment of diversity change in response to climate warming.…”

1. Climate warming and subsequent landscape transformations result in rapid ecological change in Arctic freshwaters. Here we provide a synthesis of the diversity of benthic diatoms, plankton, macrophytes, macroinvertebrates, and fish in Arctic freshwaters.2. We developed a multi-organism measure of α diversity to characterise circumpolar spatial patterns and their environmental correlates, and we assessed ecoregion-level β diversity for all organism groups across the Arctic.3. Alpha diversity was lowest at high latitudes and elevations and where dispersal barriers exist. Diversity was positively related to temperature, and both temperature and connectivity limited diversity on high latitude islands. Beta diversity was highly variable among ecoregions for most organism groups, ranging from 0 (complete similarity) to 1 (complete dissimilarity). The high degree of dissimilarity within many ecoregions illustrates the uniqueness of many Arctic freshwater communities. Northward range expansion of freshwater taxa into Arctic regions may lead toincreased competition for cold-stenothermic and cold-adapted species, and ultimately lead to the extinction of unique Arctic species. Societal responses to predicted impacts include: (1) actions to improve detection of changes (e.g., harmonised monitoring, remote sensing) and engagement with Arctic residents and Indigenous Peoples; and (2) actions to reduce the impact of unwanted changes (e.g., reductions of CO 2 emissions, action against the spread of invasive species).5. Current Arctic freshwater monitoring shows large gaps in spatial coverage, while time series data are scarce. Arctic countries should develop an intensified, longterm monitoring programme with routine reporting. Such an approach will allow detection of long-term changes in water quality, biodiversity, and ecosystem services of Arctic freshwaters.

“…Although some samples from Norway were collected much earlier than samples from Finland or Sweden, their inclusion was necessary to maximise the spatial coverage of the data. Broad‐scale river monitoring data from across the circumpolar regions typically include 2–3 decades of surveying due to the high cost and difficulties involved in accessing remote locations, and such samples have been analysed in spatial contexts to maximise the number of regions that can be considered (Izaguirre et al., 2016; Lento et al., 2022). In addition, Huttunen et al (2012) demonstrated the temporal stability of benthic macroinvertebrate assemblages across northern Fennoscandian streams (66–67°N) among years, indicating that data could be merged across years.…”

1. Arctic freshwaters support biota adapted to the harsh conditions at these latitudes, but the climate is changing rapidly and so are the underlying environmental filters. Currently, we have limited understanding of broad-scale patterns of Arctic riverine biodiversity and the correlates of α-and β-diversity.2. Using information from a database set up within the scope of the Arctic Council's Conservation of Arctic Flora and Fauna Circumpolar Biodiversity Monitoring Plan, we analysed patterns and correlates of α-and β-diversity in benthic diatom and macroinvertebrate communities across northern Norway, Sweden, and Finland.We analysed variation in total β-diversity and its replacement and richness difference components in relation to location of the river reach and its drainage basin (Baltic Sea in the south, the Barents Sea in the east and the north, and the Norwegian Sea in the west), in addition to climate and environmental variables.3. In both macroinvertebrates and diatoms, the replacement and richness difference components showed wide variation. For macroinvertebrates, the richness difference component was the more important, whereas for diatoms, the replacement component was the more important in contributing to variation in β-diversity.There was no significant difference in β-diversity between the three main drainage basins, but species composition differed among the drainage basins.4. Based on the richness difference component of β-diversity, climate variables were most strongly associated with community variation in macroinvertebrates. In diatoms, both environmental and climate variables were strongly correlated with community compositional variation. In both groups, there were also significant differences in α-diversity among the three main drainage basins, and several taxa were significant indicators of one of these drainage basins. Alpha diversity was greater in areas with a continental climate, while the oceanic areas in the west harboured greatly reduced flora and fauna.

“…Lento et al. (2022) evaluate α and β diversity of benthic macroinvertebrates in >1,500 lakes and rivers across the circumpolar region. Rarified α diversity of benthic macroinvertebrates declines with increasing latitude in both lakes and rivers, although more strongly across mainland regions than islands.…”

1. Climate change is predicted to have dramatic effects on Arctic freshwater ecosystems through changes to the abiotic template that are expected to influence biodiversity. Changes are already ongoing in Arctic systems, but there is a lack of coordinated monitoring of Arctic freshwaters that hinders our ability to assess changes in biodiversity. 2. To address the need for coordinated monitoring on a circumpolar scale, the Arctic Council working group, Conservation of Arctic Flora and Fauna, established the Circumpolar Biodiversity Monitoring Program, which is an adaptive monitoring program for the Arctic centred around four ecosystem themes (i.e., Freshwater, Terrestrial, Coastal, Marine). The freshwater theme developed a monitoring plan for Arctic freshwater biodiversity and recently completed the first assessment of status and trends in Arctic freshwater biodiversity. 3. Circumpolar Biodiversity Monitoring Program-Freshwater has compiled and analysed a database of Arctic freshwater monitoring data to form the first report of the state of circumpolar Arctic freshwater biodiversity. This special issue presents the scientific analyses that underlie the Circumpolar Biodiversity Monitoring Program-Freshwater report and provides analyses of spatial and temporal diversity patterns and the multiple-stressor scenarios that act on the biological assemblages and biogeochemistry of Arctic lakes and rivers.4. This special issue includes regional patterns for selected groups of organisms in Arctic rivers and lakes of northern Europe, Russia, and North America. Circumpolar assessments for benthic diatoms, macrophytes, plankton, benthic macroinvertebrates, and fish demonstrate how climate change and associated environmental drivers affect freshwater biodiversity. Also included are papers on spatial and temporal trends in water chemistry across the circumpolar region, and a systematic review of documented Indigenous Knowledge that demonstrates its potential to support assessment and conservation of Arctic freshwaters.
