Flow Resistance due to Aquatic Vegetation in Streams and Flumes
Ecohydrology, Volume 18, Issue 7, October‐November 2025.ABSTRACT Although several studies regarding flow resistance due to aquatic vegetation for small‐ and full‐scale are available, the scaling of small‐scale results to full‐scale conditions still needs to be investigated. In this paper, a theoretical flow resistance equation for open channels was tested using literature measurements performed for full ...

, 2018 The genus Nitella is the most species-rich within the Charales. Brazilian studies on the genus are relatively scarce and consist of floristic surveys, lacking modern and more precise information. This investigation applied scanning electron microscopy to

Disentangling the effects of climate change in a mountain lake through community structure analysis
Limnology and Oceanography, Volume 70, Issue 8, Page 2142-2157, August 2025.Abstract Pressures of climate change may trigger regime shifts in ecosystems. Identifying signs of these pressures before the critical transition remains challenging, and it could be useful to anticipate the regime shift. In this research, while exploiting the case of a lacustrine ecosystem, which passed from an unvegetated, phytoplankton‐dominated ...

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Evidence for a CO2‐concentrating mechanism in the model streptophyte green alga Chara braunii
New Phytologist, Volume 247, Issue 3, Page 1218-1233, August 2025.Summary Oxygenic photosynthesis in streptophytic algae, such as Charophyceae, is often impeded by low CO2 levels in aquatic habitats. Consequently, many algal groups evolved a CO2‐concentrating mechanism (CCM). However, its presence in Charophyceae remains controversial.

Nitella fluctuation and instability in the membrane potential near threshold [PDF]
, 1980 Excitation of Nitella internodal cell was investigated as an example of the phase transition in an open system far more thermal equilibrium. The power density spectrum of the membrane potential fluctuation had a bulge in a frequency range lower than 1 Hz

Two new species of Nitella (Characeae, Charophyceae) from arid-zone claypan wetlands in Australia [PDF]
, 2013 Two new species of Nitella Ag. are described. The species are dioecious and grow in temporary arid-zone wetlands called 'claypans'. Both have somewhat inflated, bicelluate fertile dactyls and neither species has mucus associated with the reproductive ...

A study of the new characteristic charophyte and the classification status
四川大学学报. 自然科学版, 2017 This study was focused on a special charophyte collected from Ya'an, Sichuan. Morphological observation showed that it had two-layer coronal, divided branchlets and no cortex. These were the features of Nitelleae. But there was another feature which hadn’
