Abstract Intermittent rivers and ephemeral streams (IRES) may represent over half the global stream network, but their contribution to respiration carbon dioxide (CO 2 ) emissions is largely undetermined. In particular, little known about variability drivers of in IRES sediments upon rewetting, which could result large pulses CO . We present a study examining from 200 dry reaches spanning multiple biomes. Results standardized assays show that mean increased 32‐fold 66‐fold sediment...
Climatic extreme events such as droughts (unpredictable), dry periods (predictable) or even flush floods, threaten freshwater ecosystems worldwide. The filtering mechanisms of these and their strength on communities, however, can be different among regions. While time-for-adaptation theory defines whether not water scarcity considered disturbance, the stress-dominance predicts an increase in importance environmental a decrease role biotic interactions communities with increasing stress....
The Alqueva reservoir is essential for water supply in the Alentejo region (south of Portugal). Satellite data are to overcome temporal and spatial limitations situ measurements, ensuring continuous global quality monitoring. Data between 2017 2020, obtained from OLCI (Ocean Land Color Instrument) aboard Sentinel-3, were explored. Two different methods used assess reservoir: K-means group reflectance spectra into optical types (OWT), empirical algorithms estimate parameters. Spatial (in five...
Abstract We analysed the spatial patterns in macroinvertebrate taxon richness and abundance at two scales: sampling unit basin. sampled 12 stream sites three zones of Portugal, differing climate geomorphology water chemistry. At a scale, substratum organic matter content, depth dominant size particles were correlated with numbers taxa individuals. propose that number small scale depends on individuals, which turn is result accumulation, hydrologic characteristics. The environmental...
More than half of the global river network is composed intermittent rivers and ephemeral streams (IRES), which are expanding in response to climate change increasing water demands. After years obscurity, science IRES has bloomed recently it being recognised that support a unique high biodiversity, provide essential ecosystem services functionally part networks groundwater systems. However, they still lack protective adequate management, thereby jeopardizing resources at scale. This Action...
ABSTRACT The potential importance of benthic diatoms in Mediterranean watercourses has received limited academic attention historically. This study sought to provide baseline information for this poorly studied group. Temporary and permanent Portugal differ catchment characteristics, climatic variables water chemistry. diatom communities were characterized terms ecological preferences conservation status taxa with relative abundance above 1% at least one site covering 39 temporary sites (109...
The study of lake–atmosphere interactions was the main purpose a 2014 summer experiment at Alqueva reservoir in Portugal. Near-surface fluxes momentum, heat and mass [water vapour (H<sub>2</sub>O) carbon dioxide (CO<sub>2</sub>)] were obtained with new Campbell Scientific's IRGASON Integrated Open-Path CO<sub>2</sub>/H<sub>2</sub>O Gas Analyser 3D Sonic Anemometer between 2 June October. On average, releasing energy form sensible latent flux during period. At end 75 d, total evaporation...
Two new taxa similar to Achnanthidium minutissimum were common and abundant in samples collected during a survey of benthic diatoms watercourses from mainland Portugal. They are described here as A. duriense, sp. nov. lusitanicum, In addition, the recently pseudolineare is reported various localities its ecology detail. The species Portugal compared with type material morphologically taxa: microcephalum, Achnanthes minutissima, minutissima var. cryptocephala, inconspicua nana. analysis this...
Introdução: O câncer de colo útero é uma das principais causas mortalidade entre mulheres, com o HPV oncogênico (tipos 16 e 18) como fator decisivo na sua etiologia. Além do HPV, microambiente cervical, a resposta imunológica microbiota vaginal também influenciam progressão para câncer. A vacinação contra representa um marco preventivo importante, mas enfrenta desafios cobertura aceitação. Desenvolvimento: este estudo revisou artigos selecionados no PubMed, explorando relação flora vaginal....
Abstract. Alqueva reservoir located in southeast of Portugal has a surface area 250 km2 and total capacity 4150 hm3. Since 2006 the water quality this is explored by authors using remote sensing techniques. First MERIS multi-spectral radiometer on-board ENVISAT-1 presently with MSI SENTINEL-2. The existence two satellites (A B) equipped enable to be revisited, under same viewing conditions, every 2–3 days. 2017 multidisciplinary project ALOP (ALentejo Observation Prediction systems) expands...
More than half of the world's rivers dry up periodically, but our understanding biological communities in riverbeds remains limited. Specifically, roles dispersal, environmental filtering and biotic interactions driving biodiversity are poorly understood. Here, we conduct a large-scale coordinated survey patterns drivers riverbeds. We focus on eight major taxa, including microorganisms, invertebrates plants: Algae, Archaea, Bacteria, Fungi, Protozoa, Arthropods, Nematodes Streptophyta. use...
Abstract In‐stream nitrate removal capacity may be used as a proxy for the ecosystem service of water quality regulation. It is well known that this natural function driven by abiotic and biotic factors in running environments. With regard to drivers, most literature focuses on microbial community influences, but there has been very little emphasis relationship with benthic macroinvertebrate community. Since feeds assemblages (autotrophic and/or heterotrophic biofilms) live streambed...
