Influence of the Hot-pressing Process on the Durability of Totora (Schoenoplectus Californicus C.A. Mey. Soják) Binderless Boards against Wood-decaying Organisms

open access: yesJournal of Natural Fibers, 2021
Totora (Schoenoplectus californicus C.A. Mey. Soják) is a macrophyte from the Cyperaceae family that grows in the Americas. Recent studies have shown the feasibility of producing binderless boards using different tissues of totora stems. However, no data

A DNA mini‐barcode for marine macrophytes [PDF]

open access: yesMolecular Ecology Resources, 2020
AbstractStudies focusing on marine macrophyte metabarcoding from environmental samples are scarce, due to the lack of a universal barcode for these taxa, and to their poor representation in DNA databases. Here, we searched for a short barcode able to identify marine macrophytes from tissue samples; then, we created a DNA reference library which was ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Hydrology drives facilitative and competitive strategies in freshwater macrophyte and microbial communities

open access: yesEcosphere
Pulses of resource availability along environmental gradients can filter the local and regional distribution of macrophyte and microbial mat communities in wetlands. Wetlands that experience short hydroperiods (i.e.,

THE PERMISSIBLE INPUT OF BIOGENIC ELEMENTS TO WATER BODIES WITH SLOWED AND MODERATE WATER EXCHANGE

open access: yesВодное хозяйство России: проблемы, технологии, управление, 2020
The article presents the outputs of researches on determination of permissible input of biogenic matter to water bodies with different types of moderate and slowed water exchange: that is phytoplankton, phytoplankton/macrophyte, and macrophyte types. We

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

open access: yesEcography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Les macrophytes sont-ils de bons candidats pour l'évaluation du succès d'une restauration ? L'exemple des anciens bras du Rhin reconnectés

open access: yesSciences, Eaux & Territoires, 2014
Des opérations de restauration dans la plaine d'Alsace ont conduit à reconnecter d'anciens bras latéraux du Rhin au cours principal. Les communautés végétales aquatiques sont utilisées comme indicateurs du succès de l'opération. Afin de tester cet outil,

Genetic diversity and population structure of a rare and endangered freshwater macrophyte Potamogeton rutilus Wolfg.

open access: yesActa Societatis Botanicorum Poloniae, 2023
Comprehending genetic variation and population structure is paramount for devising optimal management strategies and conservation efforts. In this study, we employed amplified fragment length polymorphism (AFLP) analysis to assess the distribution of ...

A practical guide to species trend detection with unstructured data using local frequency scaling (Frescalo)

open access: yesEcography, EarlyView.
Accurately measuring biodiversity change remains a central challenge in ecology. Beyond the general idea of quantifying temporal species frequency changes, several sampling‐related biases in data collection remain key methodological challenges to consider. Long‐term standardized ecological data are rare, and most available datasets exhibit considerable

Des méthodes basées sur les peuplements de macrophytes pour évaluer l'état écologique des milieux aquatiques

open access: yesSciences, Eaux & Territoires, 2014
Etudier les organismes vivants dans les milieux aquatiques pour en tirer des informations sur les conditions régnant dans leur milieu est l'idée fondatrice du concept de bioindication.
