Oil Things Bright and Beautiful? How Hydrocarbon Pollution Impacts Guppy Ornamentation

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Spatial variation in crude oil pollution in Trinidad leads to differing levels of pollutant exposure in connected guppy populations. Male guppy ornamentation is an important sexually selected trait affected by environmental changes. Measuring area and intensity of this ornamentation, we found guppies from anthropogenically polluted habitats had greater

Effects of salmon lice on numbers and size distributions of Atlantic salmon returning to spawn in Norwegian rivers

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
This study presents a quantitative relationship between infestations of post‐smolt recruits and size‐structured returns of mature salmon to Norwegian rivers, suggesting that louse infestation from farms may reduce returns of spawners and re‐structure the size distribution of mature river populations of Atlantic salmon.
