Acclimation of Charophytes to Spectral Composition of Light at Limiting Irradiances
ABSTRACT Irradiance is regarded as a key factor determining the maximum colonization depth (Z0) of submerged macrophytes. However, the relevance of acclimation capabilities to spectral composition under such low‐light conditions remains poorly understood.

Investigating the Role of Periphyton in Nitrification in Paddy Fields [PDF]
Soil and water pollution and waste of resources have occurred due to the excessive use of nitrogen fertilizers in paddy fields. Considering that the biofilm of periphyton formed in paddy fields is mainly responsible for the exchange of nutrients, the ...

In a benthic community on a continuous flat granite substrate in a third-order coastal forest stream, the dominant chironomid (Cricotopus) increased in number when shrimps (Macrobrachium olfersi and Potimirim glabra) and baetid ephemeropterans were ...

Periphyton communities are complex phototrophic, multispecies biofilms that develop on surfaces in aquatic environments. These communities harbor a large diversity of organisms comprising viruses, bacteria, algae, fungi, protozoans and metazoans. However,

Conditions leading to exceptionally high temperatures in shallow tropical lakes
Abstract Factors leading to exceptionally high temperatures in shallow tropical waters are examined with high‐resolution measurements and application of a 3‐dimensional hydrodynamic model in an Amazon floodplain lake. Highest near‐surface (0.05 m) temperatures in open water ranged from 31.0 to 37.5°C. Within mats of floating plants maximum temperatures

ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

The objective of the present work was to assess the possible benefits of the installation of underwater structures for periphyton in bioflocs tanks for Nile tilapia, Oreochromis niloticus, submitted to feed restriction (artificial diet). The experimental

Using Fine Sediment Monitoring to Quantify Sand Loading Over Time
ABSTRACT Riverine sand loading can lead to geomorphic change, impacting river processes like lateral migration and vertical aggradation or degradation. Yet many sediment monitoring programs track only fine sediment measurable as total suspended solids (TSS). Here, we assess the ability for TSS data to be used to determine sand loading.
