Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

Journal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods

Food potential of aquatic macrophytes [PDF]

Presents a review of the pathways in which aquatic macrophytes may be involved in the food production process, directly as human food, as livestock fodder, as fertilizer (mulch and manure, ash, green manure, compost, biogas slurry), and as food for ...

Point de vue – Des macrophytes et des humains : quel avenir possible ? [PDF]

, 2014
Considérés tantôt comme des nuisances, tantôt comme des atouts, les macrophytes restent au cœur de nombreux débats. Quelle en est l’histoire récente ? Comment envisager l’avenir avec ces acteurs importants des milieux aquatiques

Maximal Swimming Speed Explains Differences in Habitat Use Among Invasive Ponto‐Caspian Dikerogammarus Species (Crustacea, Amphipoda)

Journal of Zoology, EarlyView.
The three invasive Ponto‐Caspian Dikerogammarus species (D. bispinosus, D. haemobaphes, and D. villosus) show niche differentiation along the current velocity gradient. In the present study, we experimentally measured their maximal swimming speeds to test whether they coincide with their tolerances for currents.

Aquatic macrophytes as nature‐based solutions: Challenges and opportunities across inland and coastal waters

Limnology and Oceanography Letters
Macrophytes are foundation species whose use as nature‐based solution (NbS) in aquatic ecosystems can help reduce climate change impacts while mitigating biodiversity loss.

Relationships between relative growth rate and its components across 11 submersed macrophytes

, 2012
The relationships between relative growth rate and its components across 11 submersed macrophytes were examined in a short-term experimental study. Plants were grown in identical conditions in pots that were submersed in tanks.

For colonization success, should hosts and microbes travel alone, together, or swap partners along the way?

New Phytologist, EarlyView.
Experimental co‐introduction of duckweeds (Lemna japonica) and their microbiome in a common pond. Summary Microbiomes that enhance the performance of host plants are likely to be co‐introduced with their host during colonization because of their intimate association.

Oxygen demand during mineralization of aquatic macrophytes from an oxbow lake

Brazilian Journal of Biology
This study presents a kinetic model of oxygen consumption during aerobic decomposition of detritus from seven species of aquatic macrophytes: Cabomba furcata, Cyperus giganteus, Egeria najas, Eichhornia azurea, Salvinia auriculata, Oxycaryum cubense and ...

Submerged Macrophytes Exhibit Different Phosphorus Stoichiometric Homeostasis

Frontiers in Plant Science, 2018
Phosphorus (P) is a limiting element in many aquatic ecosystems. Excessive P input often leads to cyanobacterial bloom, thus triggering ecological imbalances and a series of environmental problems.

Duckweeds under salt stress: a meta‐analysis of growth inhibition in relation to morphological and physiological traits and a systematic review of molecular responses

New Phytologist, EarlyView.
Salinity reduces duckweed growth responses. Summary Salinity is one of the main environmental factors limiting the performance of duckweeds and despite growing ecological and biotechnological interest in these macrophytes, there is a lack of quantitative analyses of their responses to sodium chloride.
