Un nouvel article #OpenAccess du LIA MacLife ! Fruit d’une collaboration entre @inrae-france.bsky.social, @universiteuppa.bsky.social et @natureatcal.bsky.social, cette étude en Sierra Nevada explore les effets croisés du changement climatique et des invasions biologiques en rivières de montagne.

Interested in climate change, invasive predators, and cross-ecosystem linkages? Check out our newest paper in @aslo.org's L&O, from a fun experiment we ran three summers ago in California's Sierra Nevada, beautifully led by postdoc @chaevangelista.bsky.social!

Stream Channels - One of the most unique features of SNARL is the experimental stream channel system. The original channels were established by US Fish and Wildlife researchers in the 1940’s and divided Convict creek into four sections up to 400 meters in length, with individual water-control structures and moveable fish barriers. An array of new experimental stream channels was built in the 1990’s, and consisted of nine identical stream sections, with identical patterns of riffles, pools, and meanders. Each channel is one meter wide and 50 meters long, with natural sediments and cobbles laid over a rigid concrete base. The new channels provide researchers with statistically meaningful replicates for controlled comparative studies. In addition to the experimental channels and divided stream sections, researchers have access to stretches of Convict Creek above and below the reserve, and to small channels flowing through the aquatic laboratory.

We found that early low ﬂows and non-native ﬁsh had additive, but not synergistic effects on stream insect emergence. Low flows shifted community structure, and brown trout increased the emergence of small-sized groups - and benthic algal biomass!

We subjected stream channels to future low-snowpack & early snowmelt scenarios, and to presence of brown trout, a global invader. We tracked dynamics of emerging insects—a key linkage connecting streams to the adjacent terrestrial environment

New paper by @chaevangelista.bsky.social ‬ and colleagues shows how California mountain river communities can be altered by climate change, through longer low flow periods, and the interaction of a predator, here the infamous brown trout.

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

Climate-induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low-flow periods. Yet, anticipating how stream ecosystems respond to prolonged low...

Which exploitation strategy should be adopted for salmonid metapopulations? 🎣 Could knowledge of source-sink dynamics improve their management?
