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 ...

Novos registros de Nitella (Chlorophyta, Characeae) para regiões dos Estados de Mato Grosso e Mato Grosso do Sul, Brasil

Hoehnea
As Charophyceae (Chlorophyta) representam uma classe única de algas devido à sua estrutura vegetativa e porte macroscópico dos gametângios. O inventário florístico do gênero Nitella (Characeae, Chlorophyta) nos Estados de Mato Grosso (18º55'05"S e 54º50 ...

Salt tolerance at single cell level in giant-celled Characeae

Frontiers in Plant Science, 2015
Characean plants provide an excellent experimental system for electrophysiology and physiology due to: (i) very large cell size, (ii) position on phylogenetic tree near the origin of land plants and (iii) continuous spectrum from very salt sensitive to ...

Go hard or go home: Major removal of woody vegetation and sediment greatly enhances wetland plant and water beetle diversity recovery in a farmland pond landscape

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
We investigated short‐term (1–3 years) pond biodiversity responses to restoration at a variety of management intensities. Ponds undergoing the most intense intervention (major woody vegetation and sediment removal) showed the strongest biodiversity uplift. This is likely in part due to a seedbank response and highlights the value of intense restoration

A model for the concomitant early formation of dolomite and fibrous clays in coastal bay systems: Evidence from the Eocene (Paris Basin, France)

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.
ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...

The sedimentary sequence from the Lake Ķūži outcrop, central Latvia: implications for late glacial stratigraphy [PDF]

Estonian Journal of Earth Sciences, 2011
Sediment samples from an outcrop in the near-shore area of Lake Ķūži (Vidzeme Heights, Central Latvia) were investigated using palaeobotanical (pollen and macrofossil analysis) and lithological (grain-size analysis) methods and accelerator mass ...
