The benthic diatom communities were characterized in terms of ecological preferences and conservation status for taxa with relative abundance above 1% in at least one site covering 39 temporary sites (109 taxa) and 53 permanent sites (130 taxa).
Morphological variability within the Achnanthidium minutissimum species complex (Bacillariophyta): comparison between the type material of Achnanthes minutissima and related taxa, and new freshwater
Two new taxa similar to Achnanthidium minutissimum were common and abundant in samples collected during a survey of benthic diatoms in watercourses from mainland Portugal. They are described here as
Morphological reconsideration of the araphid genus Pseudostaurosira (Bacillariophyceae), a revision of Gedaniella, Popovskayella and Serratifera, and a description of a new Nanofrustulum species
This paper presents a meta-modelling study of the response of the Danube Research Institute to the build-up of carbon dioxide in the stratosphere during the period of June 21 to 29, 1997.
Monitoring the water quality in Alqueva Reservoir, Guadiana River, southern Portugal
This study presents some physical, chemical and biological monitoring results from the Alqueva Reservoir, located in the Guadiana River Basin, Portugal since the filling phase, providing an
Use of Sentinel 2 – MSI for water quality monitoring at Alqueva reservoir, Portugal
Abstract. Alqueva reservoir located in southeast of Portugal has a surface area of 250 km2 and total capacity of 4150 hm3. Since 2006 the water quality of this reservoir is explored by the authors
The Três Marias Reservoir: A sink for sediments outcoming from over-erosion of soils in Minas Gerais, Brazil
The goal of this study is defining the structure and functioning of the Tres Marias tropical reservoir, located in the Cerrado region in Brazil, through geological and chemical study of the bottom
New Species and Combinations in the Genus Geissleria (Bacillariophyceae)
Two new Geissleria species from Portugal are described from Portugal based on their morphological and ultrastructural characteristics, supporting the delimitation of the new Portuguese species.
Temporal and Spatial Variations of Secchi Depth and Diffuse Attenuation Coefficient from Sentinel-2 MSI over a Large Reservoir
A methodology developed to characterize spatial and temporal variations of Secchi depth and diffuse attenuation coefficient (both related to dissolved/suspended particles and to water transparency), using high spatial resolution satellite images from Sentinel-2 Multi-Spectral Instrument (MSI).
A predictive modelling tool for assessing climate, land use and hydrological change on reservoir quality.
Reservoirs are fundamental for water and energy supply but vulnerable to impacts including climate change. This paper outlines the steps in the development of a model to predict how climate, land use
