Genome Sequences of \u3cem\u3eFrankineae\u3c/em\u3e sp. Strain MT45 and \u3cem\u3eJatrophihabitans\u3c/em\u3e sp. Strain GAS493, Two Actinobacteria Isolated from Forest Soil

Frankiaceae are bacterial endosymbionts that are also found free-living in soil. Here, we present the genome sequences of two novel bacterial members of the order Frankiales, class Actinobacteria, isolated from temperate terrestrial forest soils. The genomes for MT45 and GAS493 indicate a genetic capacity for carbohydrate degradation but not nitrogen fixation

Up Against The Wall: The Effects of Climate Warming on Soil Microbial Diversity and The Potential for Feedbacks to The Carbon Cycle

Earth’s climate is warming, and there is evidence that increased temperature alters soil C cycling, which may result in a self-reinforcing (positive), microbial mediated feedback to the climate system. Though soil microbes are major drivers of soil C cycling, we lack an understanding of how temperature affects SOM decomposition. Numerous studies have explored, to differing degrees, the extent to which climate change may affect biodiversity. While there is ample evidence that community diversity begets ecosystem stability and resilience, we know of keystone species that perform functions whose effects far outweigh their relative abundance. In this paper, we first review the meaning of microbial diversity and how it relates to ecosystem function, then conduct a literature review of field-based climate warming studies that have made some measure of microbial diversity. Finally, we explore how measures of diversity may yield a larger, more complete picture of climate warming effects on microbial communities, and how this may translate to altered carbon cycling and greenhouse gas emissions. While warming effects seem to be ecosystem-specific, the lack of observable consistency between measures is due in some part to the diversity in measures of microbial diversity

Pandemic Genres: Processing the COVID-19 Pandemic through Electronic Literature

This essay surveys works of electronic literature and digital art initiated in the earliest months of the pandemic that are reflective of the specific conditions and anxieties of the period. Here, we offer critical readings of these works to provide a better understanding of how electronic literature and digital art were used to process the experience and communicate the experience of the COVID-19 pandemic. Through an analysis of 18 works, certain traits and commonalities are identified as characteristic of a period-specific genre of COVID E-Lit. These include: * an impulse towards the post-digital with crossovers both to analog artistic practice and forms such as net art more common to the early web; * a focus during the periods of lockdown on domestic, local, and interior environments; * digital takes on a chronicle mode of storytelling familiar from prior pandemic periods; * meditation on the loss and substitution of shared public space; * use of text generation to represent repetitive and interminable experiences of the pandemic; * consideration of the virus itself as a language and on language as a manifestation of power and control; * the influence of ubiquitous visualizations and statistical representations of the pandemic; and * a desire to wrestle with the implications of the massive cultural shift to digital platforms that took place during the pandemic.publishedVersio

DRIVERS and CONSEQUENCES of CARBON USE EFFICIENCY - and ITS MEASUREMENT in SOIL

Soils serve as massive carbon sinks, but their ability to continue this ecological service is contingent on how the resident soil microbial community will respond to the ongoing climate crisis. One key dimension of the microbial response to warming is its carbon use efficiency (CUE), or the fraction of carbon taken up by an organism which is allocated to growth rather than respiration. However, the scientific community is still in the early stages of understanding the drivers, consequences - and even accurate measurements of - CUE. In this dissertation, I first quantified the variability of CUE and its responsiveness to temperature and substrate for soil bacteria grown in the lab. I subsequently implemented this knowledge into a plant litter decomposition model to determine how including organism-level variation in CUE alters projected soil carbon stocks in a warmer world. Finally, I completed a series of numerical simulations to evaluate how robust a commonly-used method of measuring CUE in the field is to changes in the microbial community present. I found that CUE was highly variable and depended on both substrate and temperature in a bacteria-specific manner. No robust genetic or genomic markers of CUE or its temperature dependence emerged, indicative of the wide diversity of bacteria characterized in this study. Nonetheless, efficiency tended to decrease with warming more-so in taxa which were already characterized by high efficiency, causing a degree of homogenization in CUE at higher temperatures. Introducing variation in CUE temperature sensitivity to the litter decomposition model DEMENT caused additional litter carbon loss under warming, which indicates the possible importance of accounting for CUE as a niche dimension for species sorting to act upon in decomposition models. Finally, I found the 18O-H2O method of measuring CUE in mixed soil communities is particularly susceptible to misleading results when the assumption of extracellular water being the sole source of oxygen to DNA is violated. Overall, my results indicate that understanding microbial physiology is essential to both the accurate measurement and projection of CUE under the global climate crisis, but that explaining the genomic underpinning of this physiological variation remains a challenge

Lowland tundra plant stoichiometry is somewhat resilient decades following fire despite substantial and sustained shifts in community structure

The Arctic is experiencing the greatest increase in average surface temperature globally, which is projected to amplify wildfire frequency and severity. Wildfire alters the biogeochemical characteristics of arctic ecosystems. However, the extent of these changes over time-particularly with regard to plant stoichiometries relative to community structure-is not well documented. Four years after the Yukon-Kuskokwim Delta, Alaska, experienced its largest fire season, aboveground plant and lichen biomass was harvested across a gradient of burn history: unburned ("reference"), 2015 burn ("recent burn"), and 1972 burn ("historic burn") to assess the resilience of tundra plant communities to fire disturbance. Fire reduced aboveground biomass in the recent burn; early recovery was characterized by evergreen shrub and graminoid dominance. In the historic burn, aboveground biomass approached reference conditions despite a sustained reduction of lichen biomass. Although total plant and lichen carbon (C) and nitrogen (N) were reduced immediately following fire, N stocks recovered to a greater degree-reducing community-level C:N. Notably, at the species level, N enrichment was observed only in the recent burn. Yet, community restructuring persisted for decades following fire, reflecting a sustained reduction in N-poor lichens relative to more N-rich vascular plant species

OVERVÅGNINGENS KUNST - OVERVÅGNINGSDYSTOPIER OG INTERFACEBEGÆR I DET URBANE RUM I 1984, FACELESS OG ANDRE URBANE INTERFACES

THE ART OF SURVEILLANCEFor many years surveillance was perceived in a negative way, but this has changed and we increasingly are surveilled by cameras and sensors and our behaviour on-line is logged and tracked by both companies and (inter-)national intelligence. Far from generating overwhelming protests, this development is often furthered by people willingly posting personal and private data to commercial services and companies on the web. Consequently today, surveillance seems unavoidable and an integrated part of the different social and urban interfaces spreading around us. This article will discuss this cultural shift in the perception of surveillance and follow how the cultural perception of surveillance has changed from George Orwell’s dystopian 1984 to Apple’s liberating 1984 in the advert for the first Macintosh and to contemporary urban interfaces. It will do so by discussing contemporary urban surveillance art with a focus on Manu Luksch’ film Faceless (2007), which is a film made exclusively from ready-made surveillance camera footage. Besides a critical surveillance narrative, this film also shows dehumanised images of an invisible sociality that have a paradoxical beauty
