Desert Fertilization Experiment: composition of annual plants in study plots within desert preserves in and around the greater Phoenix metropolitan area, spring 2008
Launched in 2006 with support from the National Science Foundation (NSF) and leveraged by the CAP LTER, the Carbon and Nitrogen deposition (CNdep) project sought to answer the fundamental question of whether elemental cycles in urban ecosystems are qualitatively different from those in non-urban ecosystems. Ecosystem scientists, atmospheric chemists, and biogeochemists tested the hypothesis that distinct biogeochemical pathways result from elevated inorganic nitrogen and organic carbon deposition from the atmosphere to the land. To test the hypothesis, scientists examined the responsiveness of Sonoran desert ecosystems to nutrient enrichment by capitalizing on a gradient of atmospheric deposition in and around the greater Phoenix metropolitan area. Fifteen desert study sites were established, with five locations each west and east of the urban core, and in the urban core in desert preserves. In addition to the gradient of atmospheric deposition in and around the urban core, select study plots at each of the fifteen desert locations receive amendments of nitrogen, phosphorus, or nitrogen + phosphorus fertilizer. Measured variables include soil properties, perennial and annual plant growth, and atmospheric deposition of nitrogen. At the close of the initial grant period, the CAP LTER assumed responsibility for the project, renamed the Desert Fertilization Experiment, which provides a remarkable platform to study the long-term effects of nutrient enrichment on ecosystem properties. This data set features the composition of annual plants in subplots at project study sites assessed in spring 2008. These data are published independently of surveys of annual plants in subsequent years owing to slightly differnet methods employed in 2008 relative to other years. Investigators interested in annual plants composition data from other years, or for other Desert Fertilization Experiment data, should search the data repository for 'desert fertilization experiment'.

Plant aboveground biomass data: The Seasonal Effects of Nitrogen Addition in the Spring on Vegetation at Differing Times of the Growing Season
The purpose of this experiment is to measure the effect of addition of NH4NO3 in the spring on vegetation at different times during the growing season. This experiment is located within the fenced area of field C. See E001 about the construction of the fence. There are three NH4NO3 levels labeled E, G, and I as defined in fertilization details in the "microplot" category. There are 4 replicates and the treatments were randomly assigned to the 12 plots. The plots are laid out in a 3 by 4 grid and are 1.5 by 3.9 meters in area. To measure effect at different times during the growing season each plot will be sampled by clipping 0.2 m by 0.5 m quadrats every two weeks during the 1985 growing season.
Climate Change Across Seasons Experiment (CCASE) Sapling Study at the Hubbard Brook Experimental Forest: Spring Phenology
Timing of spring leaf-out of red maple and sugar maple saplings experiencing combinations of soil warming and winter freeze-thaw cycles was assessed weekly in 2014 and 2015 from late April (when growing season warming began) through early June when leaves were fully expanded. There were seven treatments for each species of maple. For each species, ten saplings experienced ambient temperatures (reference), ten experienced growing season warming with no induced freeze-thaw cycles in winter (warmed), ten in each of four groups experienced warming in the growing season coupled with two, four, six, or eight soil freeze-thaw cycles in winter (warmed + 2 FTC, warmed + 4 FTC, warmed + 6 FTC, warmed + 8 FTC), and ten experienced snow removal in winter with ambient temperatures in the growing-season (snow removal). These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
Data from: Carbon fixation by photosynthetic mats along a temperature gradient in a Tengchong hot spring
<p>Geothermal hot springs, widely distributed on Earth, are important geological green-house gas sources which contribute large amounts of CO<sub>2</sub> emission to the atmosphere. Exploring microbial carbon fixation in these springs is vital to fully understand the carbon budget in these terrestrial aquatic systems. In this study, carbon fixation rate by photosynthetic mats was determined with a <sup>13</sup>C labeling approach along a gradient of temperature (~69 - ~75 <sup>o</sup>C) in a geothermal pool at Rehai Park in Tengchong, Yunnan Province, China. Light experiments were performed to determine carbon fixation rate by both photosynthesis and chemosynthesis, while dark experiments were performed by chemosynthesis. The results showed that the highest carbon fixation rate (about 4,637 μg C/g TOC/h) was obtained in light at the lowest temperature (~69 <sup>o</sup>C) in the afternoon (1:00 to 6:00 pm), most of which (96.7%) was contributed by photosynthesis. The lowest carbon fixation rate (138 μg C/g TOC/h) was measured at the highest temperature (~75 <sup>o</sup>C), where chemosynthesis dominated over photosynthesis in carbon fixation. At these rates, the photosynthetic mats would fix 80% CO<sub>2</sub> emission during the daytime. At the end of daytime, the photosynthetic mats respired 34% -70% newly fixed organic carbon in one hour. Interestingly, both the carbon fixation rate and respiration rate decreased exponentially with increasing temperature, which may be ascribed to a temperature dependence of both microbial community composition and enzymatic activity. In summary, our study revealed that biological carbon fixation by photosynthetic mats is highly temperature dependent and significantly affects carbon cycling in hot springs.</p>

Springs ecosystem classification supplementary information
<p>Springs ecosystems are globally abundant, geomorphologically diverse, and bio-culturally productive, but are highly imperiled by anthropogenic activities. More than a century of scientific discussion about the wide array of ecohydrological factors influencing springs has been informative, but has yielded little agreement on their classification. This lack of agreement has contributed to the global neglect and degradation of springs ecosystems by the public, scientific, and management communities. Here we review the historical literature on springs classification variables, concluding that site-specific source geomorphology remains the most diagnostic approach. We present a conceptual springs ecosystem model that clarifies the central role of geomorphology in springs ecosystem development, function, and typology. We present an illustrated dichotomous key to terrestrial (non-marine) springs ecosystem types and subtypes, and describe those types. We identify representative reference sites, although data limitations presently preclude selection of continentally or globally representative reference springs of each type. We tested the classification key using data from 244 randomly selected springs of 13 major types that were inventoried in North America. The dichotomous key correctly identified springs type in 87.5% of the cases, with discrepancies primarily due to differentiation of primary versus secondary typology, and insufficient inventory team training. Using that information, we identified sources of confusion and clarified the key. Among the types that required more detailed explanation were hypocrenes, springs, in which groundwater is expressed through phreatophytic vegetation. Overall, springs biodiversity and ecosystem complexity are due, in part, to the co-occurrence of multiple intra-springs microhabitats. We describe microhabitats that are commonly associated with different springs types, reporting at least 13 microhabitats, each which can support discrete biotic assemblages. Interdisciplinary agreement on basic classification is needed to enhance scientific understanding and stewardship of springs ecosystems, the loss and degradation of which constitute a global conservation crisis.</p> <p>We provide data on springs ecosystem classification using non-sensitive springs data selected in an unbiased fashion from Springs Online (springsdata.org) to test the springs classificaiton dichotomous key and description (attached as separate pages to this dataset). </p>
Data from: Genome-wide association mapping of resistance to Septoria nodorum leaf blotch in a Nordic spring wheat collection
Parastagonospora nodorum is the causal agent of septoria nodorum blotch (SNB) in wheat. It is the most important leaf blotch pathogen in Norwegian spring wheat. Several quantitative trait loci (QTL) for SNB susceptibility have been identified. Some of these QTL are the result of underlying gene-for-gene interactions involving necrotrophic effectors (NEs) and corresponding sensitivity (Snn) genes. A collection of diverse spring wheat lines was evaluated for SNB resistance/susceptibility over seven growing seasons in the field. In addition, wheat seedlings were inoculated and infiltrated with culture filtrates (CFs) from four single spore isolates and infiltrated with semi-purified NEs (SnToxA, SnTox1 and SnTox3) under greenhouse conditions. In adult plants, the most stable SNB resistance QTL were located on 2B, 2D, 4A, 4B, 5A, 6B, 7A and 7B. The QTL on 2D was effective most years in the field. At the seedling stage, the most significant QTL after inoculation were located on 1A, 1B, 3A, 4B, 5B, 6B, 7A and 7B. The QTL on 3A and 6B were significant both after inoculation and CF infiltration, indicating the presence of novel NE-Snn interactions. The QTL on 4B and 7A were significant in both seedlings and adult plants. Correlations between SnToxA sensitivity and disease severity in the field were significant. To our knowledge, this is the first genome wide association mapping study (GWAS) to investigate SNB resistance at the adult plant stage under field conditions.
Uncovering transport, deposition and impact of radionuclides released after the early spring 2020 wildfires in the Chernobyl Exclusion Zone
<p>In the beginning of April 2020, large fires that started in the Chernobyl Exclusion Zone (CEZ) established after the Chernobyl accident in 1986 caused media and public concerns about the health impact from the resuspended radioactivity. In this paper, the emissions of previously deposited radionuclides from these fires are assessed and their dispersion and impact on the population is examined relying on the most recent data on radioactive contamination and emission factors combined with satellite observations. About 341 GBq of <sup>137</sup>Cs, 51 GBq of <sup>90</sup>Sr, 2 GBq of <sup>238</sup>Pu, 33 MBq of <sup>239</sup>Pu, 66 MBq of <sup>240</sup>Pu and 504 MBq of <sup>241</sup>Am were released in 1<sup>st</sup>–22<sup>nd</sup> April 2020 or about 1,000,000,000 times lower than the original accident in 1986 and mostly distributed in Central and East Europe. The large size of biomass burning particles carrying radionuclides prevents long-range transport as confirmed by low concentrations reported in Europe. The highest cumulative effective doses (>15 μSv) were calculated for firefighters and the population living in the CEZ, while doses were much lower in Kiev (2–5 μSv) and negligible in Europe. All doses are radiologically insignificant and no health impact on the European population is expected from the April 2020 fires.</p>

Data from: Hot spring frogs (Buergeria japonica) prefer cooler water to hot water
<p>"Hot spring frog" is an informal name used for the Japanese stream tree frog (<i>Buergeria japonica</i>), which is widely distributed in Taiwan and the Ryukyu Archipelago in Japan. Some populations of the species are known to inhabit hot springs. However, water temperature can be extremely high around the sources of hot springs. Thus, it is questionable whether <i>B. japonica</i> selectively inhabits such dangerous environments. To address this question, we conducted a series of observations of water temperature preferences of a hot spring population of <i>B. japonica</i> in Kuchinoshima Island in Japan: (1) a field observation of tadpole density in water pools of different temperatures, (2) a field observation of water temperatures where adult males appear for breeding, and (3) an indoor observation of water temperatures selected by adult females for oviposition. As a result, tadpoles showed a higher density in cooler water. Adult males avoided water pools hotter than 37 °C, and adult females selected cooler pools for oviposition. Camera records also showed that adult individuals tend to appear around cooler pools. Thus, we did not find any support for the hypothesis that hot spring frogs prefer hot water. Conversely, they apparently tended to prefer cooler water if it was available. Water temperatures around the sources of the hot spring exceed thermal tolerances of the species and could be a strong selective pressure on the population. Thus, the ability to sense and avoid lethal temperatures may be a key ecological and physiological characteristic for the species that inhabit hot springs.</p>
Data from: Phosphorus release from unamended and gypsum-or biochar-amended soils under simulated spring snowmelt and summer flooding conditions
<p>Prolonged flooding changes the oxidation–reduction status of soils, often enhancing phosphorus (P) release to overlying floodwater. We studied P release from unamended, gypsum-amended and biochar- amended soils under simulated snowmelt flooding (previously frozen, cold flooding at +4°C) and summer flooding (unfrozen, warm flooding at +22°C), using two soils, Fyala clay (FYL-Cl) and Neuenberg sandy loam (NBG-SL) from Manitoba, Canada. Amended and unamended soils were packed into vessels and flooded under cold and warm temperatures in the laboratory. Pore water and floodwater samples were taken weekly for 6 weeks after flooding (WAF) and thereafter biweekly for 10 WAF, and analyzed for dissolved reactive P (DRP), pH and cation concentrations. NBG-SL showed a significantly higher DRP concentration in pore water and floodwater despite its low Olsen P content. Redox potential (Eh) decreased slowly under cold compared to warm flooding; hence redox-induced P release was substantially lower under cold flooding. Gypsum amendment significantly decreased the floodwater DRP concentrations in NBG-SL by 38% and 35% under cold and warm flooding, respectively, but had no significant effect in FYL-Cl, which had low DRP concentrations (<1.2 mg L-1) throughout flooding period. Biochar amendment significantly increased floodwater DRP concentrations by 27 to 68% in FYL-Cl under cold and warm flooding, respectively, but had no significant effect in NBG-SL. The results indicate substantially less P release under cold, than under warm flooding. Gypsum was effective in reducing floodwater DRP concentrations only at high DRP concentrations; thus the effectiveness was greater under warm, than under cold flooding conditions.</p>
