Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Ecosystem retrogression enhances cross‐domain microbial stability and increases the genetic potential for nutrient cycling

open access: yesmLife, EarlyView.
Abstract Ecosystem retrogression drives nutrient depletion, reduced productivity, and profound reorganization of soil microbial communities. Using amplicon sequencing and genome‐resolved metagenomics, we examined how cross‐domain microbial networks and functional gene potential respond to long‐term phosphorus and nitrogen limitation along the well ...

Mirabegron and Intradetrusor Onabotulinumtoxina for Overactive Bladder in Parkinson's Disease: A Systematic Review and Meta‐Analysis

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Objective To synthesize the evidence on the efficacy and safety of mirabegron and intradetrusor onabotulinumtoxinA (BoNT‐A) as separate interventions for overactive bladder (OAB) in Parkinson's disease (PD). Methods A systematic review and meta‐analysis with parallel synthesis of two distinct interventions was conducted of randomized and ...

Seagrass species diversity in Tanzania based on morphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase
