The Impact of Biochar Addition on the Water Quality of a Lowland Peat Ecosystem

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Biochar is a refractory material in the environment, as such has been proposed in this study as a method to enhance carbon storage in peatlands. This study is the first to assess the effect of biochar on water quality and found no evidence of detrimental impact of biochar addition on water quality in and from these peat soils. Therefore, changing water

Variation in seed abundance predicts yolk fatty acid composition in a wild population of birds

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Bird embryos develop inside eggs, which contain maternal substances that can shape offspring phenotype and fitness. Yolk fatty acids are a key energy source for the developing embryo, with omega‐6 (ω‐6) and omega‐3 (ω‐3) polyunsaturated fatty acids (PUFAs) obtained exclusively from the diet.
