Protected Areas Have Not Halted Macrophyte Biodiversity Loss and Eutrophication in Northwest German Standing Waters

Journal of Vegetation Science, Volume 37, Issue 1, January/February 2026.
Since the mid‐20th century, mean site‐level macrophyte richness declined by more than a quarter across 119 standing waters of various types in northwest Germany. Within protected areas, richness was consistently higher but declined at similar rates. Communities shifted towards eutrophic‐hypertrophic indicators, underscoring the need for catchment‐wide ...

Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

The Genome of Phoebe zhennan (Lauraceae) and Comparative Genomics of Phoebe 楠木(樟科)基因组与楠属植物比较基因组学研究

Integrative Conservation, Volume 4, Issue 4, Page 584-599, December 2025.
Phoebe zhennan is a Chinese endemic and valuable timber species of Phoebe (Lauraceae). We present a chromosome‐level genome assembly of P. zhennan. Our research provides novel insights into the genome evolution of Phoebe, including whole‐genome duplication, phylogenetic relationships of magnoliids, and key MYB regulatory genes involved in lignin ...

Intraspecific trait variability is a key feature underlying the association between community‐weighted mean and abiotic gradients

Oikos, Volume 2025, Issue 12, December 2025.
Functional plant traits that influence fitness or performance provide a powerful tool for understanding and predicting how plants interact with their environment, respond to ecological changes, and contribute to ecosystem processes. To this day, most trait‐based ecological studies in both terrestrial and aquatic ecosystems have assumed that species ...
