An important component of the biological assessment stream condition is an evaluation direct or indirect effects human activities disturbances. The concept a "reference condition" increasingly used to describe standard benchmark against which current compared. Many individual nations, and European Union as whole, have codified reference in legislation aimed at protecting improving ecological streams. However, phrase has many meanings variety contexts. One primary purposes this paper bring...
Summary 1. Periphytic diatoms, macrophytes, benthic macroinvertebrates and fish were sampled with standard methods in 185 streams nine European countries to compare their response degradation. Streams classified into two main stream type groups (i.e. lowland, mountain streams); addition, the lowland grouped four more specific types. 2. Principal components analysis altogether 43 environmental parameters was used construct complex stressor gradients for physical–chemical, hydromorphological...
Many international policies encourage a switch from fossil fuels to bioenergy based on the premise that its use would not result in carbon accumulation atmosphere. Frequently cited goals at least double present global human of plant material, production which already requires dedication roughly 75% vegetated lands and more than 70% water withdrawals. However, burning biomass for energy provision increases amount air just like coal, oil or gas if harvesting decreases stored plants soils,...
Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable biodiversity loss
Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals mobilisation substantial resources. While reasons are varied, investments in both research conservation lag far behind those terrestrial marine realms. Inspired by a global consultation, we identify 15 pressing priority needs, grouped into five areas, an effort to support informed stewardship biodiversity. The proposed agenda aims advance globally as critical step improving...
The budding yeast Saccharomyces cerevisiae and the fission Schizosaccharomyces pombe are both sensitive to camptothecin, an inhibitor of DNA topoisomerase I. An S. repair mutant, rad52, is hypersensitive drug. In species, I mutants totally lacking enzyme completely resistant A strain with a mutation leading temperature-sensitive exhibits temperature dependence in its vivo response camptothecin. carrying plasmid that overproduces rad52 mutant killed by overproduction enzyme, even absence...
This paper summarizes and synthesizes the collective results that emerged from series of papers published in this issue J-NABS, places these context previously literature describing variation aquatic biota at landscape spatial scales. Classifications based on scales are used or being evaluated for use several countries bioassessment programs. Evaluation strength classification different approaches should provide insight refinement existing programs expedite development new The specifically...
Abstract The EU Water Framework Directive (WFD) requires river assessment systems based on benthic invertebrates. AQEM project is developing, at a European scale, such methodology, comparison of communities reference streams and degraded streams. focussing three main impact types: morphological degradation, organic pollution acidification. This paper presents the outline with special emphasis on: – an overview invertebrates presently applied in Europe stream typology approaches selection...
Topoisomerase inhibitors comprise an important group of agents that is used in cancer treatment. Because the development resistance to chemotherapeutic represents a major limitation chemotherapy, we investigated mechanism by murine P388 leukemia camptothecin (topoisomerase I inhibitor) or amsacrine II inhibitor). The resistant cells contained reduced levels topoisomerase activity and messenger RNA. gene these was rearranged (only one allele) hypermethylated. These alterations probably...
Summary 1. Stream communities are structured by factors acting over multiple spatial and temporal scales. Identifying what driving patterns in stream is a central aim of ecology. 2. Here we used two large European data sets fish, invertebrates, macrophytes, benthic diatoms environmental groups (lowland mountain) to determine the importance variables at different scales (geographical, regional, local) on community structure. 3. Both geographical position ecoregion were selected first...
For more than 50 years, scientific insights from surface water monitoring have supported Swedish evidence-based environmental management. Efforts to understand and control eutrophication in the 1960s led construction of wastewater treatment plants with phosphorus retention, while acid rain research 1970s contributed international legislation curbing emissions. By 1990s, long-time series were being used infer climate effects on chemistry biology. Monitoring data play a key role implementing...
The backscattering frequency responses for euphausiids and copepods are predicted using a fluid-sphere model measured physical properties the zooplankters. is also compared with resonant gas bubble equation.
Freshwater ecosystems are important for global biodiversity and provide essential ecosystem services. There is consensus in the scientific literature that freshwater vulnerable to impacts of environmental change, which may trigger irreversible regime shifts upon services be lost. profound uncertainties regarding management assessment vulnerability change. Quantitative approaches needed reduce this uncertainty. We describe available statistical modeling along with case studies demonstrate how...
Background: The development of acellular dermal matrices (ADMs) has facilitated single-stage implant breast reconstruction (IBR) following skin-sparing mastectomy. conventional approach postpectoral placement with lower pole ADM confers a good cosmetic result by improving projection and control, while minimizing issues visibility, palpability, rippling. This is balanced potential disadvantages including pain, disruption pectoral muscle function, animation. We report the results prospective...
Globalization has led to the introduction of thousands alien species worldwide. With growing impacts by invasive species, understanding invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, dynamics have been assumed follow an "invasion curve" (S-shaped curve available area invaded over time), but this dynamic lacked empirical testing using large-scale data neglects consider invader abundances. We propose "impact describing...
