Abstract In recent years, soil inoculation with cyanobacteria has become one of the most promising biotechnological strategies for restoring functionality in degraded drylands because their critical role increasing fertility and preventing erosion. Nevertheless, order to fully exploit this biotechnology on a large scale, it must still be shown whether inoculated are capable developing soils different physicochemical properties, new candidates adapted desert conditions explored. To evaluate...
Cyanobacteria are key microbes in topsoil communities that have important roles preventing soil erosion, carbon and nitrogen fixation, influencing hydrology. However, little is known regarding the identity distribution of microbial components photosynthetic assemblages form a cohesive biological crust (biocrust) drylands Europe. In this study, we investigated cyanobacterial species colonizing biocrusts three representative dryland ecosystems from most arid region Europe (SE Spain)...
Arid and semi-arid ecosystems are characterized by patchy vegetation variable resource availability. The interplant spaces of these very often covered cyanobacteria-dominated biocrusts, which the primary colonizers terrestrial key in facilitating succession other biocrust organisms plants. Cyanobacterial biocrusts regulate horizontal vertical fluxes water, carbon nutrients into from soil play crucial hydrological, geomorphological ecological roles ecosystems. In this paper, we analyze...
ABSTRACT Introduction Integrating process improvement tools into healthcare has shown promising results, yet the application of “training within industry” (TWI) still needs to be explored in this context. This study focuses on implementing job instruction (JI), one three components TWI, a large breakthrough series collaborative (BTS) middle-income country. Methods We evaluated deployment JI during nationwide initiative aimed at reducing critical healthcare-associated infections...
Abstract Dryland vegetation is limited by water scarcity, and usually appears in the form of sparsely distributed patches within a heterogeneous unvegetated matrix often covered biological soil crust. Biocrusts act as runoff sources, whereas acts sinks, reinfiltrating most run‐on from upstream biocrusted areas. Alteration biocrusts human disturbances or climate change may exert strong impact on erosion, promoting rill formation, increasing flow connectivity between source areas reducing...
Abstract Biological soil crust, or biocrust communities, are the dominating life form in many extreme habitats, such as arid and semiarid badlands, where water scarcity highly erodible substrates limit vegetation cover. While climate, biotic factors have been described environmental filters influencing distribution biomes, little is known about effect of terrain attributes on creating specific microhabitats that promote restrict colonization. This study aimed to identify main controlling...
Benthic microbial mats dominated by Cyanobacteria are important features of polar lakes. Although culture-independent studies have provided insights into the diversity Cyanobacteria, only a handful genomes been sequenced to date. Here, we applied genome-resolved metagenomics approach data obtained from Arctic, sub-Antarctic and Antarctic mats. We recovered 37 metagenome-assembled (MAGs) representing 17 distinct species, most which distantly related that so far. These include (i) lineages...
Chlorophyll a concentration (Chla) is well-proven proxy of biocrust development, photosynthetic organisms’ status, and recovery monitoring after environmental disturbances. However, laboratory methods for the analysis chlorophyll require destructive sampling are expensive time consuming. Indirect estimation by means soil surface reflectance has been demonstrated to be an accurate, cheap, quick alternative retrieval information, especially in plants. its application biocrusts yet harnessed....
Although there are simple and low-cost measures to prevent healthcare-associated infections (HAIs), they remain a major public health problem. Quality issues lack of knowledge about HAI control among healthcare professionals may contribute this scenario. In study, our aim is present the implementation project HAIs in intensive care units (ICUs) using quality improvement (QI) collaborative model Breakthrough Series (BTS).A QI report was conducted assess results national Brazil between January...
Abstract Benthic microbial mats dominated by Cyanobacteria are important features of polar lakes. Although culture-independent studies have provided insights into their diversity, only a handful genomes been sequenced to date. Here, we applied genome-resolved metagenomics approach data obtained from Arctic, sub-Antarctic, and Antarctic mats. We recovered 22 unique metagenome-assembled (MAGs) Cyanobacteria, most which distantly related that so far. These include i) lineages common in such as...
A 66-year-old man who had undergone aortic dissection repair a year earlier sought to assess the feasibility of returning high-intensity outdoor activities he long enjoyed. In response his inquiry, cardiac rehabilitation staff at Baylor Hamilton Heart and Vascular Hospital designed comprehensive testing plan that simulated specific movements anticipated requirements associated with goal activities. The included 1) lifting manipulating 50-pound suitcase, 2) hiking top Half Dome in...
Las biocostras son comunidades de organismos autótrofos y heterótrofos que viven en la superficie del 12% los suelos Tierra, donde actúan como ingenieras ecosistema. Son muy sensibles al cambio climático a las alteraciones ocasionadas por diferentes actividades antrópicas. En este trabajo, revisamos impactos ambos tipos perturbaciones, afectan negativamente ciclos biogeoquímicos, balance agua energía, aceleran procesos erosivos emisión polvo reducen biodiversidad disminuyendo capacidad...
Cyanobacteria inhabit extreme environments, including drylands, providing multiple benefits to the ecosystem. Soil degradation in warm drylands is increasing due land use intensification. Restoration methods adapted stress are being developed, such as cyanobacteria inoculation recover biocrusts. For this type of restoration method be a success, it crucial optimize survival inoculated field. One strategy harden them acclimated stressful conditions after laboratory culturing. Here, we analyzed...
Fire is a natural element of the landscape; however, it can also have serious effects on environment. Although effect fire plant communities has been broadly studied, we lack information soils. Several types post-fire treatments applied in Mediterranean areas for soil protection and potential regeneration fertility, i.e. logging or mulching. Yet, these biodiversity are not fully understood. Here, using different physical biological approaches methods, analysed impacts composition diversity...
Restoration of drylands is crucial to reverse global land degradation because these areas cover around 40% the Earth surface and host one third world population. efforts are often unsuccessful in alternative approaches need be developed, i.e., biocrust-based restoration, promote plant growth increase soil fertility stability. In this research, we cultured several biocrust-forming organisms inoculate them on degraded soils. We designed a more effective inoculum based heterotrophic bacteria...
Our objective was to evaluate 2 methods of external marker dosing, at levels forage allowance, estimate intake in beef cattle. Sixteen Aberdeen Angus steers (mean age 18 mo; 350 ± 9 kg BW), kept in- dividual pens, were used a quadruplicated 4 × Latin square design experiment, factorial arrange- ment.
