Seasonal Variation Of Bacterial Diversity Along The Marine Particulate Matter Continuum, Mireia Mestre, Juan Höfer, M. Montserrat Sala, Josep M. Gasol

Research outputs 2014 to 2021

© Copyright © 2020 Mestre, Höfer, Sala and Gasol. Seasonal dynamics of ocean prokaryotic communities in the free-living fraction have been widely described, but less is known about the seasonality of prokaryotes inhabiting marine particles. We describe the seasonality of bacterial communities in the particulate matter continuum by sampling monthly over two years in a temperate oligotrophic coastal ecosystem and using a serial filtration (including six size-fractions spanning from 0.2 to 200 μm). We observed that bacterial communities in the particulate matter continuum had annual changes following harmonic seasonal oscillations, where alpha, beta, and gamma diversity increased during the warm …

Living With Machines. Ethical Implications And Imaginative Agency As Local Tactics Of Dwelling And Resistance In Everyday Interactions With Artificial Intelligence, Ester Toribio-Roura

Articles

With the widespread of the Internet of things (IoT), algorithms are increasingly managing our everyday life. From navigating our way in cities to keeping track of our health, artificial intelligence has been beneficial to us in many ways. However, its algorithms can also be detrimental as a consequence of biased human programming. The result is that while technological progress delivers more and more human-like artificial intelligence, humans become dehumanised and therefore, disempowered in their everyday interactions with artificial intelligence.The solution(s) is not single-handed and calls for combined interventions at the macro and micro levels. Whilst reviewing recent top-down developments on …

Limited Importance Of Primary Production In The Deep Chlorophyll Layer For Macro-Zooplankton In An Oligotrophic Karst Lake: A Whole-Lake 15N Experiment, Wayne A. Wurtsbaugh, María Rosa Miracle, Antonio Camacho, Javier Armengol, Eduardo Vicente

Watershed Sciences Faculty Publications

Deep-chlorophyll layers (DCL) in oligotrophic lakes contribute significantly to primary productivity, but the importance of this production for the rest of the food web and for other strata is unknown. In Laguna El Tejo, a sheltered 1.7-ha Spanish karst lake, chlorophyll levels were < 2 μg/L in the epilimnion but reached 10 μg/L in the metalimnion and upper hypolimnion where cyanobacterial picoplankton dominated. Particulate nitrogen levels were 2-14 times higher in the metalimnion than in the epilimnion and 42 % of the primary productivity occurred in the deeper strata where the DCL was located. To address the trophic importance of the high biomass and production in the deep chlorophyll layer, we injected ¹⁵NH₄⁺ and rhodamine into a 0.5-m strata (15-16 m) in the metalimnion of the lake. The ¹⁵NH₄⁺ taken up by the nitrogen-limited phytoplankton allowed us to measure the importance of biologically mediated transport whereas the rhodamine traced physical eddy diffusion. After 28 days 55 % of the ¹⁵N could be …

Connotation Of High-Quality Development In Relative Poverty Areas Of China And Implementation Strategy, Zhou Kan, Sheng Kerong, Fan Jie, Liu Hanchu, Wu Jianxiong

Bulletin of Chinese Academy of Sciences (Chinese Version)

Poverty is a major challenge faced by human development, especially the global problem that has plagued developing countries, including China, for a long time. As rural absolute poverty population and poverty-stricken counties will achieve poverty alleviation in 2020, China's anti-poverty focus in the new era will begin to shift from targeted poverty alleviation in absolute poverty areas to high-quality development through comprehensive measures in relative poverty areas. Based on an initially constructed conceptual model of high-quality development in relative poverty areas, this article analyzed the internal and external constraints from the sustainability of individual and regional scales, and further proposed …

High-Quality Development Of National Territory Space Governance And Regional Economic Layout During 14th Five-Year Plan In China, Fan Jie

Bulletin of Chinese Academy of Sciences (Chinese Version)

During the period of 14th Five-Year Plan, modernization of space governance and optimization of regional economic layout are the important parts of planning and development. Since the reform and opening up, China's regional economic layout has adopted the guiding ideology of "some regions get rich first", which has rapidly driven the overall improvement of national strength, but the development gap between regions has continued to widen. The open economy and the non-state-owned economy are developing rapidly, but there are shortcomings in the security and advancement of the economic system, and the reform of the state-owned economy is still insufficient. China's …

Variants Of The Human Rad52 Gene Confer Defects In Ionizing Radiation Resistance And Homologous Recombination Repair In Budding Yeast, Alissa D Clear, Glenn M Manthey, Olivia Lewis, Isabelle Y Lopez, Rossana Rico, Shannon Owens, M Cristina Negritto, Elise W Wolf, Jason Xu, Nikola Kenjić, J Jefferson P Perry, Aaron W Adamson, Susan L Neuhausen, Adam M Bailis

College of Health Professions Faculty Papers

RAD52 is a structurally and functionally conserved component of the DNA double-strand break (DSB) repair apparatus from budding yeast to humans. We recently showed that expressing the human gene, HsRAD52 in rad52 mutant budding yeast cells can suppress both their ionizing radiation (IR) sensitivity and homologous recombination repair (HRR) defects. Intriguingly, we observed that HsRAD52 supports DSB repair by a mechanism of HRR that conserves genome structure and is independent of the canonical HR machinery. In this study we report that naturally occurring variants of HsRAD52, one of which suppresses the pathogenicity of BRCA2 mutations, were unable to suppress …

Seed-Transmitted Wheat Mosaic Virus In Sweet Corn In Utah, Claudia Nischwitz

Biology Faculty Publications

Wheat mosaic virus (WMoV) (syn. High Plains virus) was first observed in corn in 1993 in Colorado, Idaho, Kansas, and Texas (Seifers et al. 1997). The virus causes chlorotic streaks and mosaic on corn foliage, and it stunts ear development. When infected early in the season, plants frequently die. There are anecdotal reports of reduced seed germination rates in infected seed lots. The host range of the virus includes corn, small grains, and yellow and green foxtail. The virus is transmitted by the wheat curl mite (Aceria tosichella Keifer 1969). Seed transmission of WMoV at extremely low rates was …

The Mechanosensitive Ion Channel Msl10 Potentiates Responses To Cell Swelling In Arabidopsis Seedlings, Debarati Basu, Elizabeth S. Haswell

Biology Faculty Research

The ability to respond to unanticipated increases in volume is a fundamental property of cells, essential for cellular integrity in the face of osmotic challenges. Plants must manage cell swelling during flooding, rehydration, and pathogen invasion-but little is known about the mechanisms by which this occurs. It has been proposed that plant cells could sense and respond to cell swelling through the action of mechanosensitive ion channels. Here, we characterize a new assay to study the effects of cell swelling on Arabidopsis thaliana seedlings and to test the contributions of the mechanosensitive ion channel MscS-like10 (MSL10). The assay incorporates both …

The Effect Of Discrete Visual Perturbations On Balance Control During Gait, Lara I. Riem, Brian D. Schmit, Scott A. Beardsley

Biomedical Engineering Faculty Research and Publications

Immersive virtual reality provides a safe and costeffective approach to administrating balance disruption during ambulation. Previous research has explored the effects of applying continuous perturbations in a virtual environment to challenge balance. This pilot study investigates the ability to disrupt balance with discrete visual perturbations during ambulation in healthy young adults. During the study participants walked on a treadmill within a virtual environment. As they walked the entire visual scene was intermittently shifted to the left or right 1 meter over 1 second. The results demonstrate a significant decrease in step length (𝑝 <; 0.05) and change in center of mass excursion (𝑝 <; 0.05) across participants (𝑁=13). Changes in gait lasted up to three steps after application, suggesting a consistent challenge to dynamic balance control as a result of the discrete visual perturbation. Further, participants did not demonstrate a reduction in response to the discrete visual perturbation with repeated exposure. The results indicate that discrete visual perturbations of a virtual scene can be used to challenge gait and modulate center of mass sway. The use of visual perturbations within a virtual environment to challenge dynamic balance could provide a safer and more affordable avenue for balance rehabilitation by reducing the need for systems that physically perturb balance.
