description: Globular clusters are dense collections of hundreds of thousands of stars found around all bright galaxies. Being much brighter than individual stars, globular clusters can be studied at much greater distances. In my thesis I studied the chemical compositions of over a thousand globular clusters around thirteen galaxies. By measuring the ratio of hydrogen to heavy elements such calcium in the globular clusters and using these ratios to infer relative ages, I was able to study the formation history of these globular clusters. By understanding more about how globular clusters form, I was able to learn about how galaxies form.

description: Cloning multiple DNA fragments for delivery of several genes of interest into the plant genome is one of the main technological challenges in plant synthetic biology. Despite several modular assembly methods developed in recent years, the plant biotechnology community has not widely adopted them yet, probably due to the lack of appropriate vectors and software tools. Here we present Plant X-tender, an extension of the highly efficient, scarfree and sequence-independent multigene assembly strategy AssemblX,based on overlapdepended cloning methods and rare-cutting restriction enzymes. Plant X-tender consists of a set of plant expression vectors and the protocols for most efficient cloning into the novel vector set needed for plant expression and thus introduces advantages of AssemblX into plant synthetic biology. The novel vector set covers different backbones and selection markers to allow full design flexibility. We have included ccdB counterselection, thereby allowing the transfer of multigene constructs into the novel vector set in a straightforward and highly efficient way. Vectors are available as empty backbones and are fully flexible regarding the orientation of expression cassettes and addition of linkers between them, if required. We optimised the assembly and subcloning protocol by testing different scar-less assembly approaches: the noncommercial SLiCE and TAR methods and the commercial Gibson assembly and NEBuilder HiFi DNA assembly kits. Plant X-tender was applicable even in combination with low efficient homemade chemically competent or electrocompetent Escherichia coli. We have further validated the developed procedure for plant protein expression by cloning two cassettes into the newly developed vectors and subsequently transferred them to Nicotiana benthamiana in a transient expression setup. Thereby we show that multigene constructs can be delivered into plant cells in a streamlined and highly efficient way. Our results will support faster introduction of synthetic biology into plant science.

description: Antibiotic resistance is one of the greatest public health threats of our time, and the bacterium Staphylococcus aureus, of which there are numerous drug-resistant and drug-sensitive strains, is a pathogen of worldwide concern. Scientists are turning their focus to underexplored marine ecosystems to identify novel antibacterial agents effective against S. aureus. Here, we report inhibition of S. aureus strains Newman and USA300 by extracts from Saccharina latissima (sugar kelp), grown and harvested in the Western Gulf of Maine, USA. We examined how time of harvest throughout the growing season as well as the drying method pre-extraction affected the antimicrobial activity of the kelp extracts. Optimal antimicrobial activity was observed at the beginning of April (203 days since sporing), when increased water pH and higher salinity levels were also observed. Oven-dried crude extracts showed greater inhibition against S. aureus Newman, whereas freeze-dried crude extracts demonstrated greater inhibition against S. aureus USA300. Overall, our data indicate that cultivated S. latissima from the Western Gulf of Maine possesses significant value-added antimicrobial activity and identify early spring as an optimal harvest time to harness antimicrobial activity.

description: Seaweed aquaculture is one of the fastest growing marine sectors with 31.2 million tonnes year–1 of harvest worth over 11.7 billion USD. Commercial operations still rely on traditional techniques but innovative strategies are essential for future expansion. The present paper reports on a simple device that could effectively segregate non-fused haploid gametes from diploid zygotes in the green alga Ulva lactuca. The differential phototactic behaviour of gametes and zygotes was used for their separation. Approximately 56.2% non-fused haploid gametes and 5.3% diploid zygotes were separated after 5 min and after 1 hr and 2 hr, the composition of gametes was 26.6 and 8.8%, respectively while that of zygotes 32.7 and 57.4%, respectively. The effects of extrinsic abiotic factors, including light, temperature, salinity, photoperiod, dehydration and thallus fragmentation, on the induction of gametogenesis was found to be limited at 35°C (13.33 ± 5.77%) and a short day 9:15 h light:dark photoperiod (20 ± 4.08%), while dehydration treatments enhanced spore induction. This study demonstrated the efficient and cost-effective utilisation of locally available materials in producing a simple, small, precise, durable and easy to use system, which also saved on energy. The effective segregation of non-fused gametes from zygotes aids in cytological preparation, bio-chemical characterisation investigations as well as breeding and hybridisation all of which have direct implications on the future farming of Ulva and other species of seaweeds with similar life phases.

description: Employees have become an inevitable part of company image. But when employers make judgements and hire on the basis of attracting the 'right' kind of people, they leave themselves open to charges of discrimination. US clothing retailer Abercrombie & Fitch found this out the hard way. It was recently ruled against in a long running court case brought by a young Muslim woman who was denied a job at the retailer because she wore a headscarf. Abercrombie & Fitch has since replaced its infamous 'look policy' which banned caps and black clothing and sought people with a 'preppy style', with a new dress code it says allows customer service staff to be 'more individualistic'. It has also changed its hiring practices to not consider attractiveness. Store staff, previously referred to as 'models' by the company are now 'brand representatives'. Closer to home, fitness retailer Lorna Jane recently raised the ire of some Australians by advertising for a 'Receptionist/Fit Model', outlining specific body size requirements. It later clarified that it had decided to combine a traditional back-office role with a front office one so that the successful applicant could 'liaise directly with customers on a day-to-day basis, receive their feedback and allow Lorna Jane to deliver an even better product to benefit our customers and their active lifestyles'.

description: Structural colour occurs when nanoscale structures interfere with incident light transmission and reflect particular wavelengths. The brown alga Ericaria selaginoides (Fucales, Phaeophyceae) has an opalescent photonic crystal anatomy that creates the blue colour of this seaweed but which responds to light, leading to speculation that the crystals have a photosynthetic role by modifying light transmission. Here, we characterize the colour response of E. selaginoides using time-lapse photography to capture responses to light treatments of different timing, duration, intensity and spectrum. The amount of light drove the colour response, with the most intense blue found in the dark which reduced rapidly in strong light and was not spectrum dependent. Chlorophyll a fluorometry showed that the maximum quantum efficiency of photosynthesis coincided with strong blue colouration but was reduced over two to three hours of illumination. This supports opalescent photonic crystals having a photosynthetic role by regulating light transmission to chloroplasts. Studies such as this could be used to improve solar cell efficiency and increase crop yield through the use of bio-inspired self-tuning mechanisms to optimize light transmission.

description: We describe the use of a novel, computerized, multiple outdoor microalgal growth system to achieve conditions maximizing high photosynthesis and biomass production rates. We applied this system to determine the effects of multiple environmental and culture parameters such as light, temperature, pH, and mode of mixing and CO2 supply, and their combinations on the rates of algal photosynthesis, respiration, and growth. We continuously monitored the following parameters: pH, temperature, dissolved oxygen, and light, concomitantly with algal growth and biomass production rates. In particular, we likewise monitored and determined the dramatic effects of CO2 supply, mixing by paddle wheel or bubbling air modes, on algal biomass production. The isolated and synergistic effects of each factor and operation regime were measured and are discussed. We found that the diel range of maxima to minimal pH and oxygen levels strongly correlated with container performance, and were controllable by CO2 supply and mixing regime. We conclude that mixing by bubble aeration was the most important growth-rate controlling factor. It limited the build-up of high oxygen and pH levels that reduce photosynthesis that were measured by O2 evolution. In this study, OD measurements calibrated with biomass concentrations were used to calculate growth rates and estimate the photosynthetic rates of the microalgae. The potential of algae as a source of food, feed, biofuel, and fine chemicals has been widely recognized, but their competitiveness depends on areal yields. Our results allow us to recommend culture parameters that increase areal biomass yields, regardless of the algal species, thereby bringing microalgal mass culture closer to economic viability.

description: Groups of proximate continental islands may conceal more tangled phylogeographic patterns than oceanic archipelagos as a consequence of repeated sea level changes, which allow populations to experience gene flow during periods of low sea level stands and isolation by vicariant mechanisms during periods of high sea level stands. Here, we describe for the first time an ancient and diverging lineage of the Italian wall lizard Podarcis siculus from the western Pontine Islands. We used nuclear and mitochondrial DNA sequences of 156 individuals with the aim of unraveling their phylogenetic position, while microsatellite loci were used to test several a priori insular biogeographic models of migration with empirical data. Our results suggest that the western Pontine populations colonized the islands early during their Pliocene volcanic formation, while populations from the eastern Pontine Islands seem to have been introduced recently. The inter-island genetic makeup indicates an important role of historical migration, probably due to glacial land bridges connecting islands followed by a recent vicariant mechanism of isolation. Moreover, the most supported migration model predicted higher gene flow among islands which are geographically arranged in parallel. Considering the threatened status of small insular endemic populations, we suggest this new evolutionarily independent unit be given priority in conservation efforts.

description: Background: A strong health workforce is a key building block of a well-functioning health system. To achieve health systems goals, policymakers need information on what works to improve and sustain health workforce performance. Most frameworks on health workforce planning and policymaking are high-level and conceptual, and do not provide a structure for synthesizing the growing body of empirical literature on the effectiveness of strategies to strengthen human resources for health (HRH). Our aim is to create a detailed, interactive logic model to map HRH evidence and inform policy development and decision-making. Methods: We reviewed existing conceptual frameworks and models on health workforce planning and policymaking. We included frameworks that were: (1) visual, (2) comprehensive (not concentrated on specific outcomes or strategies), and (3) designed to support decision-making. We compared and synthesized the frameworks to develop a detailed logic model and interactive evidence visualization tool. Results: Ten frameworks met our inclusion criteria. The resulting logic model, available at hrhvisualizer.org , allows for visualization of high-level linkages as well as a detailed understanding of the factors that affect health workforce outcomes. HRH data and governance systems interact with the context to affect how human resource policies are formulated and implemented. These policies affect HRH processes and strategies that influence health workforce outcomes and contribute to the overarching health systems goals of clinical quality, responsiveness, efficiency, and coverage. Unlike existing conceptual frameworks, this logic model has been operationalized in a highly visual, interactive platform that can be used to map the research informing policies and illuminating their underlying mechanisms. Conclusions: The interactive logic model presented in this paper will allow for comprehensive mapping of literature around effective strategies to strengthen HRH. It can aid researchers in communicating with policymakers about the evidence behind policy questions, thus supporting the translation of evidence to policy.

description: Energy Transition Pathways for Zambia: A Modelling Approach Using OseMOSYS

Abstract

Zambia's energy sector is heavily reliant on hydropower, which accounts for over 83% of its 3,800 MW installed capacity as of December 2023. This dependency, coupled with the impacts of climate change, has led to increasing energy insecurity, particularly during frequent droughts, which disrupt electricity supply. Additionally, the country faces significant challenges in extending electricity access, especially in rural areas where the average access rate is about 8%. In response, the Zambian government has set ambitious targets to diversify the energy mix to achieve 30% electricity production from variable renewable sources. To support Energy Transition Pathways for Zambia and sustainable development, study employed the Advanced Energy System Modelling Using OseMOSYS an Open-Source Energy Modelling System to explore three energy transition scenarios: Business-As-Usual (BAU), Government Renewable Energy Policy (REW), and Drought Impact Scenario (DIS). The scenarios assess the integration of renewable energy, technological advancements, and policy interventions up to 2070. The results highlight the critical need for diversification in Zambia's energy mix. The REW scenario, which emphasizes renewable energy integration, shows significant potential for reducing greenhouse gases from about 2000 ktCO2 to about 1600 ktCO2 and stabilizing investment costs. The DIS scenario underscores the importance of resilient strategies in mitigating the impacts of droughts on the hydropower-dependent power system. Overall, this study provides essential insights and policy recommendations for guiding Zambia's transition towards a more sustainable and resilient energy future.

description: Background: Patients with metastatic, castration-resistant prostate cancer (mCRPC) present with an increased tumor burden in the skeleton. For these patients, Lutetium-177 (Lu-177) radioligand therapy targeting the prostate-specific membrane antigen (PSMA) has gained increasing interest with promising outcome data. Patient-individualized dosimetry enables improvement of therapy success with the aim of minimizing absorbed dose to organs at risk while maximizing absorbed dose to tumors. Different dosimetric approaches with varying complexity and accuracy exist for this purpose. The Medical Internal Radiation Dose (MIRD) formalism applied to tumors assumes a homogeneous activity distribution in a sphere with unit density for derivation of tumor S values (TSV). Voxel S value (VSV) approaches can account for heterogeneous activities but are simulated for a specific tissue. Full patient-individual Monte Carlo (MC) absorbed dose simulation addresses both, heterogeneous activity and density distributions. Subsequent CT-based density weighting has the potential to overcome the assumption of homogeneous density in the MIRD formalism with TSV and VSV methods, which could be a major limitation for the application in bone metastases with heterogeneous density. The aim of this investigation is a comparison of these methods for bone lesion dosimetry in mCRPC patients receiving Lu-177-PSMA therapy. Results: In total, 289 bone lesions in 15 mCRPC patients were analyzed. Percentage difference (PD) of average absorbed dose per lesion compared to MC, averaged over all lesions, was + 14 ± 10% (min: − 21%; max: + 56%) for TSVs. With lesion-individual density weighting using Hounsfield Unit (HU)-to-density conversion on the patient’s CT image, PD was reduced to − 8 ± 1% (min: − 10%; max: − 3%). PD on a voxel level for three-dimensional (3D) voxel-wise dosimetry methods, averaged per lesion, revealed large PDs of + 18 ± 11% (min: − 27%; max: + 58%) for a soft tissue VSV approach compared to MC; after voxel-wise density correction, this was reduced to − 5 ± 1% (min: − 12%; max: − 2%). Conclusion: Patient-individual MC absorbed dose simulation is capable to account for heterogeneous densities in bone lesions. Since the computational effort prevents its routine clinical application, TSV or VSV dosimetry approaches are used. This study showed the necessity of lesion-individual density weighting for TSV or VSV in Lu-177-PSMA therapy bone lesion dosimetry.
Expected properties of the first gravitational wave signal detected with pulsar timing arrays

description: In this paper we attempt to investigate the nature of the first gravitational wave (GW) signal to be detected by pulsar timing arrays (PTAs): will it be an individual, resolved supermassive black hole binary (SBHB), or a stochastic background made by the superposition of GWs produced by an ensemble of SBHBs? To address this issue, we analyse a broad set of simulations of the cosmological population of SBHBs, that cover the entire parameter space allowed by current electromagnetic observations in an unbiased way. For each simulation, we construct the expected GW signal and identify the loudest individual sources. We then employ appropriate detection statistics to evaluate the relative probability of detecting each type of source as a function of time for a variety of PTAs; we consider the current International PTA (IPTA), and speculate into the era of the Square Kilometre Array (SKA). The main properties of the first detectable individual SBHBs are also investigated. Contrary to previous work, we cast our results in terms of the detection probability (DP), since the commonly adopted criterion based on a signal-to-noise ratio threshold is statistic-dependent and may result in misleading conclusions for the statistics adopted here. Our results confirm quantitatively that a stochastic signal is more likely to be detected first (with between 75% to 93% probability, depending on the array), but the DP of single-sources is not negligible. Our framework is very flexible and can be easily extended to more realistic arrays and to signal models including environmental coupling and SBHB eccentricity.

description: The scientific goal of my PhD is to understand how the evolution of galaxies is affected by the environment in which they reside. I have analysed a sample of distant galaxy clusters, studying the properties of galaxies in dense environments, where interactions with other galaxies are more probable, at early cosmic epochs. The main result of my thesis is that the environment regulates the star-formation timescales and induces morphological transformations in galaxies. My thesis opens new questions, however, which pose scientific cases for the next generation of telescopes and instruments as well as theoretical models.

description: The COVID-19 outbreak and related public health guidelines have changed the daily lives of Canadians and restricted opportunities for healthy movement behaviours for children. The purpose of this study was to explore how parents experienced the pandemic-related restrictions and how they impacted their children’s movement behaviours. Methods: Twenty-nine semi-structured one-on-one interviews were conducted (June–July 2020) with parents of children (5–11 years old) in Ontario and British Columbia. Interviews lasted between 24–104 min, were audio-recorded, transcribed verbatim, and thematically analyzed. Results: Findings emphasized various individual (e.g., motivation), interpersonal (e.g., parent work schedule), built (e.g., closure of parks) and natural environment (e.g., weather) factors related to children’s movement behaviours. The findings highlighted the loss of structured activities and destinations for children’s physical activity, and restricted opportunities for outdoor play exacerbated by shrinking childhood independent mobility. Conclusion: Families are adapting to many pandemic-related challenges including adhering to public health restrictions, parents juggling multiple roles, conducting work and school from home, as well as exacerbating factors like weather. It will be important to continue to encourage outdoor time, support policies and practice that facilitate independent mobility, and develop centralized resources that help families in the maintenance of healthy movement behaviours.

description: Solar wind forecasting plays a crucial role in space weather prediction, yet significant uncertainties persist due to incomplete magnetic field observations of the Sun. Isolating the solar wind forecasting errors due to these effects is difficult. This study investigates the uncertainties in solar wind models arising from these limitations. We simulate magnetic field maps with known uncertainties, including far-side and polar field variations, as well as resolution and sensitivity limitations. These maps serve as input for three solar wind models: the Wang-Sheeley-Arge (WSA), the Heliospheric Upwind eXtrapolation (HUXt), and the European Heliospheric FORecasting Information Asset (EUHFORIA). We analyze the discrepancies in solar wind forecasts, particularly the solar wind speed at Earth's location, by comparing the results of these models to a created "ground truth" magnetic field map, which is derived from a synthetic solar rotation evolution using the Advective Flux Transport (AFT) model. The results reveal significant variations within each model with a RMSE ranging from 59-121 km/s. Further comparison with the thermodynamic Magnetohydrodynamic Algorithm outside a Sphere (MAS) model indicates that uncertainties in the magnetic field data can lead to even larger variations in solar wind forecasts compared to those within a single model. However, predicting a range of solar wind velocities based on a cloud of points around Earth can help mitigate uncertainties by up to 20-77%.

description: Estuaries are sources of nitrous oxide (N2O) and methane (CH4) to the atmosphere. However, our present knowledge of N2O and CH4 emissions from estuaries in the tropics is very limited because data are scarce. In this study, we present first measurements of dissolved N2O and CH4 from two estuaries in a peat-dominated region of northwestern Borneo. Two campaigns (during the dry season in June 2013 and during the wet season in March 2014) were conducted in the estuaries of the Lupar and Saribas rivers. Median N2O concentrations ranged between 7.2 and 12.3 nmol L-1 and were higher in the marine end-member (13.0 ± 7.0 nmol L-1). CH4 concentrations were low in the coastal ocean (3.6 ± 0.2 nmolg L-1) and higher in the estuaries (medians between 10.6 and 64.0 nmol L-1). The respiration of abundant organic matter and presumably anthropogenic input caused slight eutrophication, which did not lead to hypoxia or enhanced N2O concentrations, however. Generally, N2O concentrations were not related to dissolved inorganic nitrogen concentrations. Thus, the use of an emission factor for the calculation of N2O emissions from the inorganic nitrogen load leads to an overestimation of the flux from the Lupar and Saribas estuaries. N2O was negatively correlated with salinity during the dry season, which suggests a riverine source. In contrast, N2O concentrations during the wet season were not correlated with salinity but locally enhanced within the estuaries, implying that there were additional estuarine sources during the wet (i.e., monsoon) season. Estuarine CH4 distributions were not driven by freshwater input but rather by tidal variations. Both N2O and CH4 concentrations were more variable during the wet season. We infer that the wet season dominates the variability of the N2O and CH4 concentrations and subsequent emissions from tropical estuaries. Thus, we speculate that any changes in the Southeast Asian monsoon system will lead to changes in the N2O and CH4 emissions from these systems. We also suggest that the ongoing cultivation of peat soil in Borneo is likely to increase N2O emissions from these estuaries, while the effect on CH4 remains uncertain.
Chaperone Networks in Fungal Pathogens of Humans

description: The heat shock proteins (HSPs) function as chaperones to facilitate proper folding and modification of proteins and are of particular importance when organisms are subjected to unfavourable conditions. The human fungal pathogens are subjected to such conditions within the context of infection as they are exposed to human body temperature as well as the host immune response. Herein, the roles of the major classes of HSPs are briefly reviewed and their known contributions in human fungal pathogens are described with a focus on Candida albicans, Cryptococcus neoformans, and Aspergillus fumigatus. The Hsp90s and Hsp70s in human fungal pathogens broadly contribute to thermotolerance, morphological changes required for virulence, and tolerance to antifungal drugs. There are also examples of J domain co-chaperones and small HSPs influencing the elaboration of virulence factors in human fungal pathogens. However, there are diverse members in these groups of chaperones and there is still much to be uncovered about their contributions to pathogenesis. These HSPs do not act in isolation, but rather they form a network with one another. Interactions between chaperones define their specific roles and enhance their protein folding capabilities. Recent efforts to characterize these HSP networks in human fungal pathogens have revealed that there are unique interactions relevant to these pathogens, particularly under stress conditions. The chaperone networks in the fungal pathogens are also emerging as key coordinators of pathogenesis and antifungal drug tolerance, suggesting that their disruption is a promising strategy for the development of antifungal therapy.

description: The conserved VPS13 proteins constitute a new family of lipid transporters at membrane contact sites. These large proteins are suspected to bridge membranes and form a direct channel for lipid transport between organelles. Mutations in the 4 human homologs (VPS13A–D) are associated with a number of neurological disorders, but little is known about their precise functions or the relevant contact sites affected in disease. In contrast, yeast has a single Vps13 protein which is recruited to multiple organelles and contact sites. The yeast model system has proved useful for studying the function of Vps13 at different organelles and identifying the localization determinants responsible for its membrane targeting. In this review we describe recent advances in our understanding of VPS13 proteins with a focus on yeast research.

description: This research introduces a method for determining the best player in the Australian Football League (AFL). All of a player’s involvements in games are assessed using a concept of equity – the expected value of the next score to occur in the game. Players who consistently improve a team’s likelihood of scoring, or decrease the opponent’s likelihood of scoring, are rewarded with high performance measures. A summary of player performance over the past two seasons of games has been adopted by the league as the Official AFL Player Ratings.

description: Arctia matronula helena (Dubatolov & Kishida, 2004) (Figs 1 G-H, 2C)
 Pericallia matronula helena Dubatolov & Kishida, 2004; Tinea 18 (3): 226-227, fig. 8-10, 17-19. Type locality: “Southern Kuriles, South- Western Kunashir, Cape Ivanovsky”.
 Diagnosis. In addition to significant genetic differences (1.2%), A. m. helena has two subterminal spots (large and small) on the forewings (large spot is smaller or absent for the nominotypical subspecies, and small one is absent), and also the merging antemedial spots on the hindwings (they are not merging for the nominotypical subspecies, but there are exceptions) (Fig. 1). This subspecies is characterized by the apical valva processes noticeably narrowed to the apex, with well visible broadening in the central part; the dorsal basal processes of the costa of the valva are narrow, finger-like, two times longer than the ventral one (Dubatolov & Kishida 2004).
 Distribution: South Kuriles: Kunashir; Japan: Hokkaido, Honshu (Dubatolov 2010).

Stickstoffeinträge in der FFH-Verträglichkeitsprüfung: Critical Loads, Bagatellschwelle und Abschneidekriterium

description: For the last ten years impacts from nitrogen deposition within appropriate assessments has been a controversial issue discussed by many experts in Germany. More recently results from a R&D project funded by the Federal Highway Research Institute (BASt) have been published to establish a method on the assessment for road projects. Adverse effects are assessed in a staged approach based on the concept of critical loads: if total environmental deposition is lower than critical loads of the most sensitive feature of the site, no likely significant effects have to be expected. Project contributions up to a de-minimis value of 0.3 kg N ha-1y-1are considered as being too small to be measurable. Neither could nitrogen deposition of up to this value be detected in the field nor could damages be attributed to projects contributing such small amounts. Project contributions lower than the proposed threshold thus exert only hypothetical risks that do not justify or even demand refusals of project under Article 6.3. Only project contributions above the cut off criterion have to be considered within an appropriate assessment in combination with other projects. With view on the protected site another threshold of 3 % of the critical load is applied that can be exceeded not only by single projects but also in combination. Its application does not depend on background deposition. It depends on the specific sensitivity of the habitat precautionarily described by critical loads. Examination of scientific results on the effects,particularly along roads has shown that a value of 3 % of a particular critical load clearly lies below detectable adverse effects on the conservation status of natura 2000 habitats. Both thresholds are very low and thus in line with the precautionary approach prescribed by the Habitats Directive. The assessment approach encompasses legal as well as scientific confidence. It also adheres to the principle of proportionality and has proven to be functional in practice. As nitrogen inputs up to 0.3 kg N ha-1y-1 cannot be realistically attributed to a particular project, they should rather be described as diffuse part of the background deposition. High background deposition in turn should be lowered by the most efficient measures to stay in accordance with the requirement under the Habitats Directive to avoid deterioration. Very small project contributions as accepted by the proposed process will not constitute an obstacle for this.Quelle: http://www.afsv.de
