9 p, 3.7 MB Successful sulphide-driven partial denitrification : Efficiency, stability and resilience in SRT-controlled conditions / Polizzi, Cecilia (University of Florence. Department of Civil and Environmental Engineering) ; Gabriel, David (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Munz, Giulio (University of Florence. Department of Civil and Environmental Engineering)
Partial denitrification is emerging as a valuable solution for NO supply in Anammox systems. When reduced sulphur compounds are used as electron donors, S-driven Partial Autotrophic Denitrification (PAD) can also be achieved, allowing for an integrated autotrophic nitrogen (N) and sulphur (S) removal from liquid and gaseous streams.

(Oil Crops Research Institute of Chinese Academy of Agricultural Sciences) ; Palet i Ballús, Cristina (Universitat Autònoma de Barcelona. Departament de Química)
Rice and rapeseed agricultural wastes, as nonliving biomass, are proposed for heavy metal remediation in polluted effluents (chromium, cadmium, copper and lead). The physicochemical characterization of these biomasses shows that the surface of both sorbents is negatively charged (zeta potential), the surface area of sorbents is 4. [...]

29 p, 4.7 MB Microbiota profiling with long amplicons using Nanopore sequencing : full-length 16S rRNA gene and the 16S-ITS-23S of the rrn operon / Cuscó, Anna (Universitat Autònoma de Barcelona. Vetgenomics) ; Catozzi, Carlotta (Universitat Autònoma de Barcelona. Servei Veterinari de Genètica Molecular (SVGM)) ; Viñes, Joaquim (Universitat Autònoma de Barcelona. Servei Veterinari de Genètica Molecular (SVGM)) ; Sánchez Bonastre, Armando (Universitat Autònoma de Barcelona. Servei Veterinari de Genètica Molecular (SVGM)) ; Francino, Olga (Universitat Autònoma de Barcelona. Servei Veterinari de Genètica Molecular (SVGM))
Background: Profiling the microbiome of low-biomass samples is challenging for metagenomics since these samples are prone to contain DNA from other sources (e. g. host or environment). The usual approach is sequencing short regions of the 16S rRNA gene, which fails to assign taxonomy to genus and species level. [...]

Climate change effects on marine ecosystems include impacts on primary production, ocean temperature, species distributions, and abundance at local to global scales. These changes will significantly alter marine ecosystem structure and function with associated socio-economic impacts on ecosystem services, marine fisheries, and fishery-dependent societies. [...]

32 p, 1.3 MB Identifying potential applications for residual biomass from urban agriculture through eco-ideation : tomato stems from rooftop greenhouses / Manríquez-Altamirano, Ana (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Sierra-Pérez, Jorge (Universitat Autònoma de Barcelona.

Departament d'Enginyeria Química, Biològica i Ambiental) ; Gabarrell Durany, Xavier (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Considering that urban agriculture (UA) is currently on the rise due to its multiple benefits in addition to environmental ones, it would also be necessary to foresee the flow of solid waste it generates, which if not properly managed or used, could become a new waste problem within the cities. [...]
Afterwards, a creative session was held where specialists in order to identify possible applications of the stems through group techniques for the generation of ideas and the evaluation of concepts. Finally, tests were carried out with the material and a semi-quantitative evaluation of the resulting concepts was carried out using an eco-design metric. [...]

The soil quality index (SQI) is based on several key indicators and is used to assess soil quality. More than 250,000 ha of walnut saplings (Juglans regia L. ) were planted in previous cropland areas in the Sichuan Basin, China, using a range of soil cover types that may affect soil quality with effects that are unclear.

12 p, 505.6 KB Root traits and their potential links to plant ideotypes to improve drought resistance in common bean / Polania, Jose (Universitat Autònoma de Barcelona. Laboratori de Fisiologia Vegetal) ; Poschenrieder, Charlotte (Universitat Autònoma de Barcelona. Laboratori de Fisiologia Vegetal) ; Rao, Idupulapati (United States Department of Agriculture, USA) ; Beebe, Stephen E (Centro Internacional de Agricultura Tropical (CIAT), Colombia)
Drought stress limits growth and yield of crops, particularly under smallholder production systems with minimal use of inputs and edaphic limitations such as nitrogen (N) deficiency. The development of genotypes adapted to these conditions through genetic improvement is an important strategy to address this limitation. [...]

28 p, 1.5 MB Effects of decadal experimental drought and climate extremes on vegetation growth in Mediterranean forests and shrublands / Liu, Daijun (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Zhang, Chao (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Estiarte, Marc (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Increased drought combined with extreme episodes of heatwaves is triggering severe impacts on vegetation growth, particularly for plant communities in arid and semiarid ecosystems. Although there is an abundance of short-term field drought experiments in natural ecosystems, remaining knowledge gaps limit the understanding and prediction of vegetation growth to ongoing and future climate scenarios.

Increased inputs of ecosystem nitrogen (N) and phosphorus (P) may affect the activity of soil enzymes that play essential roles in the metabolization of carbon (C), N and P for microbial growth. However, the associations between soil enzymatic activities and N and P availability remain poorly understood. [...]
