“…Salmonids are often culturally symbolic and economically important for tourism and recreation (e.g. Butler et al 2009;Winfield et al 2019). Thus, documenting the potential negative consequences of climate change on these fish can serve as a powerful tool to motivate public concern and action toward mitigating climate change impacts.…”

Warming winters threaten peripheral Arctic charr populations of Europe

As the global climate warms, the fate of lacustrine fish is of huge concern, especially given their sensitivity as ectotherms to changes in water temperature. The Arctic charr (Salvelinus alpinus L.) is a salmonid with a Holarctic distribution, with peripheral populations persisting at temperate latitudes, where it is found only in sufficiently cold, deep lakes. Thus, warmer temperatures in these habitats particularly during early life stages could have catastrophic consequences on population dynamics. Here, we combined lake temperature observations, a 1-D hydrodynamic model, and a multi-decadal climate reanalysis to show coherence in warming winter water temperatures in four European charr lakes near the southernmost limit of the species’ distribution. Current maximum and mean winter temperatures are on average ~ 1 °C warmer compared to early the 1980s, and temperatures of 8.5 °C, adverse for high charr egg survival, have frequently been exceeded in recent winters. Simulations of winter lake temperatures toward century-end showed that these warming trends will continue, with further increases of 3–4 °C projected. An additional 324 total accumulated degree-days during winter is projected on average across lakes, which could impair egg quality and viability. We suggest that the perpetuating winter warming trends shown here will imperil the future status of these lakes as charr refugia and generally do not augur well for the fate of coldwater-adapted lake fish in a warming climate.

“…Over the 34-year period, the dietary importance of the native cold water salmonids, Arctic Char and Brown Trout Salmo trutta, decreased while the introduced warm water cyprinid Roach increased. Over approximately the same period, the individual condition of Northern Pike decreased (Winfield et al 2008b), likely due to a marked Accepted Article population decline in Arctic Char (Winfield et al 2008a(Winfield et al , 2019. Local decline of this high-profile salmonid is also related to reduced oxygen availability at greater depths (Jones et al 2008) and increased sedimentation on its spawning grounds (Winfield et al 2015), both of which are driven in large part by eutrophication and climate change.…”

How Does Climate Change Affect Emergent Properties of Aquatic Ecosystems?

Emergent properties of ecosystems are community attributes, such as structure and function, that arise from connections and interactions (e.g., predator-prey, competition) among populations, species, or assemblages that, when viewed together, provide a holistic representation that is more than the sum of its individual parts. Climate change is altering emergent properties of aquatic ecosystems through component responses, a combination of shifts in species range, phenology, distribution, and productivity, which lead to novel ecosystems that have no historical analog. The reshuffling, restructuring, and rewiring of aquatic ecosystems due to climate impacts are of high concern for natural resource management and conservation as these changes can lead to species extinctions and reductions in ecosystem services. Overall, we found that substantial progress has been made to advance our understanding of how climate change is affecting emergent properties of aquatic ecosystems. However, responses are incredibly complex, and high uncertainty remains for how systems will reorganize and function over the coming decades. This cross-system perspective summarizes the state of knowledge of climate-driven emergent properties in aquatic habitats with case studies that highlight mechanisms of change, observed or anticipated outcomes, as well as insights into confounding non-climate effects, research tools, and management approaches to advance the field.

The 9th International Charr Symposium convened on 18-21 June 2018, in Duluth, Minnesota, USA, to gather scientists with an interest in charr biology and management from the entire geographical range of the genus Salvelinus. The symposium was attended by 169 individuals from six countries, and included 99 oral and 32 poster presentations, 28 of which were published in the ensuing proceedings. Topic areas of presentations and publications included (1) cultural anthropology; (2) genetics, evolution, taxonomy, and systematics; (3) behavior, movement, and habitat; (4) reproductive ecology, developmental ontogeny, and physiology; (5) population ecology, dynamics, and life history; (6) trophic ecology, parasites, predators, toxicology, and pollution; and (7) management. Research reported in these proceedings has built upon the history of earlier symposiums and will be continued with the 10th symposium scheduled to convene in Nikko City, Tochigi Prefecture, Japan, in 2021.
