New article: Simple experimental designs are underestimating drought impacts on rivers. Our meta-analysis (1284 effect sizes, 53 experiments) shows BACI designs detect 2× stronger effects than simpler ones. onlinelibrary.wiley.com/doi/10.1111/...

Widespread Underestimation of Drought Impacts on River Ecosystems Due to Weak Experimental Designs

Experimental design strongly influences the detectability and magnitude of estimated drought impacts. Simpler designs underestimate impacts relative to the more complex, but relatively rare (< 35% of...

Selection against dispersers: sex, age and origin-dependent fitness differences in wild Atlantic salmon

Abstract. Local adaptation is often portrayed as uniform fitness disadvantages of immigrants relative to locals. Yet dispersal costs vary with origin, sex

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!

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. doi.org/10.1002/lno....

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...

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/...
