title: Co-exposure of uranyl acetate and sodium arsenite differentially alters gene expression in CD3/CD28 activated CD4+ T-cells.

description: Communities in the western region of the United States experience environmental exposure to metal mixtures from living in proximity to numerous unremediated abandoned uranium mines. Metals including arsenic and uranium co-occur in and around these sites at levels higher than the United States Environmental Protection Agency maximum contaminant levels. To address the potential effect of these metals on the activation of CD4+ T-cells, we used RNA sequencing methods to determine the effect of exposure to uranyl acetate, sodium arsenite or a mixture of uranyl acetate and sodium arsenite. Oxidative stress is a mechanism proposed for metal toxicity, but findings for uranium differ across cell models. No significant changes in oxidative stress genes were detected for uranyl acetate, in contrast to sodium arsenite. Sodium arsenite induced a dose dependent effect on activation associated gene expression, targeting immune response genes at the lower dose. While uranyl acetate alone did not significantly alter activation associated gene expression, the mixture demonstrated a combined effect relative to sodium arsenite alone. The results demonstrate the need to investigate uranium alone and in metalloid mixtures at environmentally relevant concentrations to better understand the toxicological impact of these mixtures on T-cell activation, function and immune dysregulation.

title: Effects of chronic nutrient enrichment on plant diversity and ecosystem productivity, 2008-2019

description: Human activities are enriching many of Earth's ecosystems with biologically limiting mineral nutrients such as nitrogen (N) and phosphorus (P). In grasslands, this enrichment generally reduces plant diversity and increases productivity. The widely demonstrated positive effect of diversity on productivity suggests a potential negative feedback, whereby nutrient induced declines in diversity reduce the initial gains in productivity arising from nutrient enrichment. In addition, plant productivity and diversity can be inhibited by accumulations of dead biomass, which may be altered by nutrient enrichment. Over longer timeframes, nutrient addition may increase soil fertility by increasing soil organic matter and nutrient pools. We examined the effects of 5-11 years of nutrient addition at 47 grasslands in twelve countries. Nutrient enrichment increased aboveground live biomass and reduced plant diversity at nearly all sites, and these effects became stronger over time. We did not find evidence that nutrient induced losses of diversity reduced the positive effects of nutrients on biomass, however nutrient effects on live biomass increased more slowly at sites where litter was also increasing, regardless of plant diversity. This work suggests that short-term experiments may underestimate the long term nutrient enrichment effects on global, grassland ecosystems.

title: Data for "Perceptions of green space usage, abundance, and quality of green space were associated with better mental health during the COVID-19 pandemic among residents of Denver"

description: Background: The COVID-19 pandemic has impacted both physical and mental health. This study aimed to understand whether exposure to green space buffered against stress and distress during the COVID-19 pandemic while taking into account significant stressors of the pandemic.
 
Methods: We leveraged a cross-sectional survey on green space exposure and mental health among residents of Denver, CO that ran from November 2019 through January 2021. We measured objective green space as the average NDVI (normalized difference vegetation index) from aerial imagery within 300m and 500m of the participant’s residence. Perceived green space was measured through Likert scores on five questions about vegetation near the home that captured perceived abundance, visibility, access, usage, and quality of green space. We used generalized linear models to assess the relationship between each green space exposure variable and perceived stress (PSS-4), depression (CES-D-10), or anxiety (MMPI-2) adjusted for sociodemographic and COVID-19 impact variables. 
 
Results: We found significantly higher depression scores for all covid periods compared to the “before covid” period, and significantly higher anxiety scores during the “fall wave” compared to earlier periods. Adjusted for sociodemographic and pandemic stressors, we found that spending a lot of time in green space (usage) was significantly associated with lower anxiety and depression. We also observed significantly lower depression scores associated with NDVI in both buffers (objective abundance) and significantly lower anxiety scores with perceived abundance of green space. There was some evidence of lower anxiety scores for people reporting having high quality green spaces near the home (quality). We did not observe significant associations for any green space metric and perceived stress after adjustment for confounding variables. 
 
Conclusion: Our work provides further evidence of mental health benefits associated with green space exposure during the COVID-19 pandemic even after adjustment for sociodemographic variables and significant pandemic-related stressors.

title: Species loss in global grasslands: 2017-2019

description: These data support an examination of the effect of nutrient supply and herbivore density on species diversity. We analyzed the effects of experimental manipulations of nutrient supply (nitrogen, phosphorus, potassium and micronutrients) and herbivore presence on species richness across a range of spatial scales (0.01 – 75 m2). Data are included from 30 sites in 10 countries which are part of the Nutrient Network (NutNet, http://www.nutnet.org) distributed experiment. Data tables are arranged by treatment: from control plots at 30 sites and from two experiments at subsets of the sites: the Multiple-nutrient experiment (21 sites) and the Consumer-nutrient experiment (16 sites). Sampling over 3 years (2017-2019). From the paper abstract (Seabloom et al, "Species Loss Due to Nutrient Addition Increases with Spatial Scale in Global Grasslands"): Effects of human-induced changes to nutrient supplies and herbivore density on species diversity vary with spatial scale, because coexistence mechanisms are scale dependent. This scale dependence may alter the shape of the species-area relationship (SAR), which can be described by changes in species richness (S) as a power function of the sample area (A): S=cAz, where c and z are constants. We analyzed the effects of experimental manipulations of nutrient supply and herbivore density on species richness across a range of scales (0.01 – 75 m2) at 30 grasslands in 10 countries. We found that nutrient addition reduced the number of species that could coexist locally, indicated by the SAR intercepts (log c), but did not affect the SAR slopes (z). As a result, proportional species loss due to nutrient enrichment was largely unchanged across sampling scales, while total species loss increased over threefold across our range of sampling scales.

title: Fungal necromass chemistry from 28 tissues

description: 1. Fungi represent a rapidly cycling pool of carbon (C) and nitrogen (N) in soils. Understanding of how this pool impacts soil nutrient availability and organic matter fluxes is hindered by uncertainty regarding the dynamics and drivers of fungal necromass decomposition. 2. Here we assessed the generality of common models for predicting mass loss during fungal necromass decomposition and linked the resulting parameters to necromass substrate chemistry. We decomposed 28 different types of fungal necromass in laboratory microcosms over a 90-day period, measuring mass loss on all types, and N release on a subset of types. We characterised the initial chemistry of each necromass type using: 1) fiber analysis methods commonly used for plant tissues, 2) initial melanin and nitrogen (N) concentrations, and 3) Fourier transform infrared (FTIR) spectroscopy to assess the presence of bonds associated with common biomolecules. 3. We found universal support for the asymptotic model of decomposition, which assumes that fungal necromass consists of an exponentially decomposing “fast” pool, and a “slow” pool that decomposes at a rate approaching zero. The strongest predictor of the fast pool decay rate (k) was the proportion of cell soluble components, though initial N concentration also predicted k, albeit more weakly. The size of the slow pool was best predicted by the acid non-hydrolysable fraction, which was positively correlated with melanin-associated aromatics. Nitrogen dynamics varied by necromass type, ranging from net N release to net immobilisation. The maximum quantity of N immobilised was inversely related to cell soluble contents and k, as positively related to FTIR spectra associated with cell wall polysaccharides. 4. Collectively, our results indicate that the decomposition of fungal necromass in soils can be described as having two distinct stages that are driven by different components of substrate C chemistry, with implications for rates of N availability and organic matter accumulation in soils.

title: Synthesizing community changes to global change treatments using the CoRRE (Community Responses to Resource Experiments) database - Data to accompany Avolio et al. 2021

description: These are the required data to do all subsequent analyses in Avolio et al. 2021 in Ecology Letters using the Community Responses to Resource Experiments database (corredata.weebly.com). Paper abstract: Global change is impacting plant community composition, but the mechanisms underlying these changes are unclear. Using a dataset of 58 global change experiments, we tested the five fundamental mechanisms of community change: changes in evenness and richness, re-ordering, species gains and losses. We found 71% communities were impacted by global change treatments, and 88% of communities that were exposed to two or more global change drivers were impacted. Further, all mechanisms of change were equally likely to be affected by global change treatments – species losses and changes in richness were just as common as species gains and re-ordering. We also found no evidence of a progression of community changes, e.g., re-ordering and changes in evenness did not precede species gains and losses. We demonstrate that all processes underlying plant community composition changes are equally affected by treatments and often occur simultaneously, necessitating a wholistic approach to quantifying community changes.

title: Experimental N addition across a N deposition gradient

description: Fungal decomposition of soil organic matter is partly driven by soil nitrogen (N) availability. This ecosystem process is being jeopardized by changes in N inputs that have resulted from a tripling of atmospheric N deposition in the last century. Soil fungi are impacted by atmospheric N deposition as community composition shifts due to higher N availability, as soils are acidified, or as micronutrients become increasingly limiting. Fungal communities that persist with chronic N deposition may be enriched with traits that enable them to tolerate environmental stress, which may trade-off with traits enabling organic matter decomposition. We hypothesized that fungal communities would respond to N deposition by shifting community composition and functional gene abundances toward those that tolerate stress but are weak decomposers. We sampled soils at seven eastern US hardwood forests where ambient N deposition varied from 3.2 – 12.6 kg N ha-1 y-1, five of which also have experimental plots where atmospheric N deposition was simulated through fertilizer application treatments (25 – 50 kg N ha-1 y-1). We found that fungal community and functional responses to chronic fertilizer treatments varied across the ambient N deposition gradient.

title: Soil fungal community and activity under dominant plant species at the Sevilleta National Wildlife Refuge, New Mexico: October 2013

description: We measured fungal composition and activity in the soil under dominant plant species across a grassland to shrubland transition to determine if shrubs cultivate soil microbial communities as they encroach grasslands. The project was conducted in the northern Chihuahuan desert at the Sevilleta National Wildlife Refuge (site of the Sevilleta LTER) in New Mexico on October 20, 2013. Soils were collected under one shrub (Larrea tridentata) and three grass (Bouteloua eriopoda, Bouteloua gracilis, Pleuraphis jamesii) species in grassland, shrubland, and the ecotone region between grasslands and shrublands. Soil fungal communities were evaluated using DNA amplicon sequencing and fungal activity was quantified using several extracellular enzyme activity assays. Soil texture and soil chemistry were also measured.

title: Can we manage a future with more fire? Effectiveness of defensible space treatment depends on housing amount and configuration

description: Context: Fire in forested wildland urban interface (WUI) landscapes is increasing throughout the western United States. Spatial patterns of fuels treatments affect fire behavior, but it is unclear how fire risk and fuel treatment effectiveness will change under future conditions. Objectives: (1) How do area burned, forest and fuel characteristics, and fire risk change over time under 21st-century climate? (2) When defensible space fuels treatments are applied around all houses, which scenarios of WUI housing amount and configuration minimize fire risk? Methods: In generic 10,000-ha US Northern Rocky Mountain subalpine forest landscapes, we simulated 21 scenarios differing in fuels treatment, housing amount and configuration (neutral landscape models), and projected future climate using the process-based model iLand. We compared fire risk at three scales: 1-ha home ignition zone (HIZ), 9-ha safe suppression zone (SSZ), and landscape. Results: Under warm-dry climate, annual area burned increased, but area burned at high fire intensity peaked in the 2060s and then declined sharply; fire risk followed similar trends. Defensible space treatments maintained low flame lengths in HIZs. Clustered housing was more effective at reducing SSZ risk compared to dispersed housing. At landscape scales, treating more of the landscape reduced fire risk but configuration was unimportant. Conclusions: The most effective strategy for reducing fire risk depends on the scale at which risk is assessed. Clustering WUI developments and treating between 10 to 30% of the landscape every 10 years can reduce fire risk across multiple scales.

title: SMB01 Variation in soil respiration and bacterial community due to species-specific plant-soil history at konza prairie

description: We conducted a “home vs. away” plant-soil feedback greenhouse experiment using two C3 grass species (Bromus inermis and Pascopyrum smithii) grown in soil collected from Konza Prairie. We used a closed-circuit CO2 trapping method and isotopic analysis to differentiate between root-derived and SOM-derived CO2 production. We investigated how soil chemistry and soil bacterial communities differed in soils with a history of B. inermis vs soils with a history of P. smithii.
