Conservation of tropical and subtropical marine-freshwater migrants for ecosystem services
Diadromous marine-freshwater migrants contribute to vital ecosystem services. Yet,
species in tropical and subtropical latitudes remain understudied and are threatened
by dams and their ineffective ma...

Diadromous animals bridge marine and freshwater ecosystems — yet remain critically understudied in the tropics. Our new mini-review in @cp-trendsecolevo.bsky.social maps ecosystem services, threats, and a path forward for research and conservation.

How do we know the magnitude of a biological invasion? How do we compare invasions of tiny organisms like ants with that of larger ones like deer? Simple. Compare their total biomasses. In our new paper in Bioscience, we do just this.

Cross-ecosystem linkages between freshwater insects and riparian birds across the USA - Nature Ecology & Evolution
Aquatic insects such as mayflies, stoneflies and caddisflies are widely used for freshwater biomonitoring and could provide resource pulses to terrestrial insectivores. Here the authors show a positiv...

Rivers aren’t just warming: they’re being reshaped by extreme events
Our new paper in @natrevbiodiv.nature.com shows how floods, droughts & heatwaves are pushing ecosystems past their limits, with recovery no longer guaranteed
We can build resilience, but it requires a shift in how we manage rivers

Starting my US journey by concluding the remaining undescribed shrimps from Hong Kong!
We describe three new cryptic species of dwarf shrimps in the Caridina serrata complex. There are now ~17 species from the 4 previously known!
