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 ...

Stereochemical Studies of Complex Molecules by Collisionally Induced Decomposition of Doubly Charged Ions. Nuphar Alkaloids

, 1991
Electron ionization of sulphur-containing Nuphar alkaloids leads to the formation of easily detectable, doubly-charged species. The study of charge-separation reactions by collision experiments allows us to determine the intercharge distances.

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

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 ...

Characterization the complete chloroplast genome of Euryale ferox (Nymphaeaceae), an medicinal plant species in China

Mitochondrial DNA. Part B. Resources, 2020
Euryale ferox belongs to the family Nymphaeaceae that has been used as foods and medicines in China. In this study, we had been completed the complete chloroplast genome of Euryale ferox, which is 159,930 bp in length and has four sub-regions.
