As dozens of frog species have declined across Central America, scientists have witnessed a remarkable chain of events: With fewer tadpoles to eat mosquito larvae, rates of mosquito-borne malaria in the region have climbed, resulting in a fivefold increase in cases. https://wapo.st/4paBuuT

We also found that fishes are accumulating risk faster than their zooplankton prey during key times of year. A pattern that hints at the potential for trophic mismatches that could affect the whole food web. We also found strong spatial patterns, with the strongest divergence in more saline regions.

By modeling how long-term population trends and variability impact decline probability, we examined how risk fluctuates throughout the year for age-0 fishes. We found that risk can vary from month to month, highlighting that risk might not be consistent even within the same life stage.

Our paper on drought & riparian phenology is out in @globalchangebio.bsky.social, skillfully led by PhD candidate Rose Mohammadi! Upshot: #Drought pushes down water tables & shortens tree growing seasons by intermittent streams - and that response is visible from space #timeseries
How vulnerable are riparian trees to drought? Using groundwater and satellite data from a California waterhsed, our new paper found that trees by drying rivers lost up to 5 weeks of growing season, suggesting they’re nearing critical groundwater limits.
