Seasonal differences in predation risk among seagrass epifauna species stabilize community‐level predation over time

open access: yesEcology, Volume 107, Issue 5, May 2026.

Despite this, ecological research is often focused on measuring average predation risk at the community level. While this can give important information about overall trophic transfer and ecological efficiency, it ignores ...

Are Toxic Butterflies More Easily Detected by Human ‘Predators’?

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Aposematic signals are often thought to be conspicuous and stable across environments. Yet, butterflies can have distinct colours on their dorsal and ventral sides which contradict this prediction. We found that despite toxic butterflies having similar detectability on both sides, only dorsal detectability positively correlated with toxicity.
