📊 40 ans de suivi du saumon de la Nivelle (1984–2024)

Are you involved in ecological forecasting in Europe?
We’re mapping forecasting applications across the continent — from SDMs to observatories with predictive potential.
Our goal: make EU forecasting more connected and identify both immediate and long-term forecasting potential.

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.

Raincloud plots showing the effect of treatment combinations on benthic algae biomass at the end of the experiment. Dots represent the samples (n = 12 per treatment), boxplots and half violin plots represent the probability density of the data.
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!
Temporal variation in emerging insect abundance (mean and SE) over the experiment in current and early low-flow treatments
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
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.

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!
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.

After years of non-stop brainstorming and hard work with
@alamarins.bsky.social & co, we're thrilled to present IBASAM (v3): a spatially explicit demo-genetic individual-based model for anadromous salmonids (meta)populations. @inrhttps://ibe.pensoft.net/articles.php?id=153305
Over the moon to finally share our new study in @science.org led by the amazing @jack-brand.bsky.social!
Pharmaceutical pollution at environmentally realistic levels alters behaviour and migration in Atlantic salmon, directly affecting survival

Coastal steelhead trout in California.
A study of the 2012–2016 California drought chronicles how low river flows during the breeding season caused Chinook salmon to shift downriver and caused steelhead and coho salmon to fail to breed entirely in some tributaries and watersheds. In PNAS: www.pnas.org/doi/10.1073/...
A new UC Berkeley study reveals how one dry winter decimated salmon and trout populations across Northern California — and how they made a comeback.

New paper out! An analysis of recent advances and challenges in tag miniaturization. I had a good time drawing Figure 3 (see below). Small things can help ensure the tagged animals recover fully!

Delighted to share our new paper in Ecology Letters:
Variation in Salmon Migration Phenology Bolsters Population Dynamics but is Threatened by Drought.

Which exploitation strategy should be adopted for salmonid metapopulations? 🎣 Could knowledge of source-sink dynamics improve their management?
Our latest paper is just out!

Simulations results 📈 suggest being not selective as the best strategy 💡
What a good way to ring in the new year! Our new paper is (finally) out in Ecology Letters!

We looked at climate driven phenological patterns across food webs in the San Francisco, Chesapeake, and Massachusetts Bay estuaries.
Thanks!
