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 ...

Germination and seedling development in Stratiotes aloides L. [PDF]

Aquatic Botany, 1995
Abstract Stratiotes aloides L. seeds need neither light, nor oxygen, nor vernalization to germinate but the germlings need light and oxygen for further development. Germination, however, is delayed strongly by the mechanical resistance of the seed coat. After liberation from the fruit seeds float probably because small gas bubbles are trapped between

Ecotoxicology of Mercerized Cellulose–Treated Tannery Effluents Using Salvinia auriculata (Salviniaceae) as a Bioindicator

Environmental Toxicology, Volume 40, Issue 12, Page 1358-1374, December 2025.
ABSTRACT Given the growing concern over the environmental impacts of industrial effluents, particularly from tanneries, assessing the ecotoxicological risks associated with these effluents, even after remediation treatments, is crucial. Therefore, we aimed to evaluate the potential effects of exposure to raw and treated tannery effluents with ...

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Allelopathic inhibition of phytoplankton by exudates from Stratiotes aloides

, 2005
The allelopathic potential of exudates from the aquatic macrophyte Stratiotes aloides on the growth of phytoplankton was investigated. A selection of phytoplankton species, occurring in habitats similar to that of Stratiotes, was used: two cyanobacterial

Garden Ponds: Hidden Sources for Plant Invasions?

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Private garden ponds are increasingly popular among homeowners and can, to some extent, compensate for the loss of natural habitats, but they may be sources of invasive species as pond owners often introduce alien ornamental species. We assessed the popularity, distribution and sources of six invasive macrophyte taxa (Elodea spp., Eichhornia ...

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

FEBS Letters, Volume 599, Issue 22, Page 3355-3368, November 2025.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...
