Data from: Climate, invasive species and land use drive population dynamics of a cold-water specialist
Climate change is an additional stressor in a complex suite of threats facing freshwater biodiversity, particularly for cold-water fishes. Research addressing the consequences of climate change on cold-water fish has generally focused on temperature limits defining spatial distributions, largely ignoring how climatic variation influences population dynamics in the context of other existing stressors. We used long-term data from 92 populations of bull trout Salvelinus confluentus – one of North America's most cold-adapted fishes – to quantify additive and interactive effects of climate, invasive species and land use on population dynamics (abundance, variability and growth rate). Populations were generally depressed, more variable and declining where spawning and rearing stream habitat was limited, invasive species and land use were prevalent and stream temperatures were highest. Increasing stream temperature acted additively and independently, whereas land use and invasive species had additive and interactive effects (i.e. the impact of one stressor depended on exposure to the other stressor). Most (58%–78%) of the explained variation in population dynamics was attributed to the presence of invasive species, differences in life history and management actions in foraging habitats in rivers, lakes and reservoirs. Although invasive fishes had strong negative effects on populations in foraging habitats, proactive control programmes appeared to effectively temper their negative impact. Synthesis and applications. Long-term demographic data emphasize that climate warming will exacerbate imperilment of cold-water specialists like bull trout, yet other stressors – especially invasive fishes – are immediate threats that can be addressed by proactive management actions. Therefore, climate-adaptation strategies for freshwater biodiversity should consider existing abiotic and biotic stressors, some of which provide potential and realized opportunity for conservation of freshwater biodiversity in a warming world.

FIGURE 1. Photo of a live specimen of Obama nungara, taken in Petite France in the commune of Saint Paul, La Réunion. Photo by Régis Bretzner, taken 10 June 2021. The specimen is brown on the back, with darker brown striae, a reddish tip, and with a cream stripe running a short distance from the head towards the tail, but which soon disappears into the general colour of the back.

FIGURE 2. Photo of a live specimen of Obama nungara, taken in la Plaine des Grègues in the commune of Saint Joseph, La Réunion. Specimen collected 22 April 2021 by Renaud Hoarau, photograph taken by Nicolas Huet. The photo clearly shows the dark brown striae on the brownish coloured back, and the whitish under surface.
Data for Land-sea linkages depend on macroalgal species, predator invasion history in a New Zealand archipelago
<p>Seabirds on islands create a circular seabird economy - whereby they feed in the ocean, transport marine-derived nutrients onshore to their breeding colonies, and then seabird-derived nutrients run off into the ocean, enriching nearshore ecosystems. Invasive predators reduce seabird colonies and nutrient subsidies; thus, predator eradication is critical for restoring seabird islands. Few studies have linked nearshore marine recovery to terrestrial ecosystem attributes and none have in temperate zones. Here, we tested the influence of seabird driven soil nutrients, terrestrial abiotic variables, and marine variables on nearshore algal communities using in-depth repeated sampling of four islands in a New Zealand island archipelago. We show seabird land-sea linkages are disrupted when predators invade, and are not restored three decades after invasive predator removal in the studied archipelago. Our study is the first account of how seabird influences on land impact nearshore marine environments on islands cleared of invasive predators in temperate ecosystems. Such information can help provide baseline information for which abiotic and ecological variables are most important when studying the linkages from land to sea in island ecosystems.</p>
