Sevilleta Field Station Meteorological Network (SevMET): High frequency measurements from the Five Points Meteorological Station (FVPT), Sevilleta National Wildlife Refuge, NM, USA, 2024-ongoing.
The Sevilleta Field Station Meteorological Network (SevMET) is a spatially distributed, long-term climate monitoring network established to enhance and expand climate monitoring across a variety of dryland ecosystems (e.g., grasslands, shrublands, woodlands) within the Sevilleta National Wildlife Refuge in central New Mexico. Ecosystem processes in drylands are strongly regulated by climatic drivers that are highly variable in space and time, both within and among years. Therefore, accurate measurement of environmental variables at high spatial and temporal resolution is fundamental to understanding biophysical processes in these ecosystems. SevMET consists of fifteen standardized research-grade weather stations located across multiple dryland ecosystem types (e.g., grasslands, shrublands, woodlands) representative of the southwestern US. Stations continuously measure a standard suite of meteorological variables at five-minute intervals, including air temperature, relative humidity, precipitation, photosynthetically active radiation, incoming shortwave radiation, wind speed and direction, dew point, vapor pressure, and, at a subset of stations, barometric pressure. Stations also measure a suite of soil parameters (bulk electrical conductivity, dielectric permittivity, temperature, and volumetric water content) at six depths (5, 10, 20, 30, 40, and 50 cm) below the ground surface using 1-2 integrated soil profilers. Additionally, phenocams at each station capture images at thirty-minute intervals during daylight hours. This data package contains high-frequency meteorological measurements from the Five Points Meteorological Station (FVPT). Phenocam images can be accessed through the PhenoCam Network at: https://phenocam.nau.edu/webcam/sites/sevmetfvpt/. These data complement and extend meteorological data recorded by an adjacent station (Met49), accessible at: https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-sev&identifier=1.
Text-fig. 2. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate,, NM S 4764, x 3. Specimen with ventral arm coiling. The specimen is on its dorsum in slate with all five rays curled ventrally inward toward mouth area on underside of disk. Barely visible are tips of two jaws; slightly exposed are proximal parts of rays in oral view extending outward from disk. The location of abrupt ventral bending of rays is indicated by emergence from slate of five rays in aboral view that point inward toward buried disk. Based on ventral bending of rays and intimate association with crinoids Eospondylus has been interpreted as stratigraphic first occurrence of Order Euryalida, which contains epizoic gorgonocephalid and euryalid basket-stars of modern oceans. This status is rejected using new evidence from isolated vertebrae.

Point Frame Measurements of Moss and Vascular Frequencies Under Increasing N Deposition Over Five Years, 2011-2015
Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1. Bogs, being ombrotrophic, may be especially susceptible to increasing N deposition. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a bog near Mariana Lakes, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). Anchored point frames were established at each plot and measure at 30 points along the frame each year in July. We used absolute frequencies of Sphagna and vascular plants to examine species and community responses to N treatment. Increasing N input led to decreased frequency of S. fuscum in the third through fifth year of N addition (Fig. 10A) and an increased frequency of S. magellanicum in the second through fifth year of N addition Dominant shrubs, all shrubs, and all vascular plant species frequencies generally increased with increasing N input, with those increases all significant in 2013-2015 (Fig. 10 G-I). Water addition alone had no significant effect on the frequency of vascular plant species or groups in any of the five years (p >= 0.12). At Mariana Lakes Bog, we observed changes in vegetation even at low experimental N loadings, with vegetation progressively changing over the 5 years of the study (Figs. 10,11). These results suggest that bogs that have persisted under very low ambient N deposition may be especially sensitive to increasing N deposition, in terms of plant species relative abundances and plant community composition.
Point Frame Measurements of Poor Fen Moss and Vascular Frequencies Under Increasing N Deposition Over Five Years, 2011-2015
Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1.

Anchored point frames were established at each plot and measure at 30 points along the frame each year in July. We used absolute frequencies of Sphagna and vascular plants to examine species and community responses to N treatment. Increasing N input led to led to decreased abundance of S. fuscum and increased abundance of S. angustifolium, S. magellanicum, Andromeda polifolia, Vaccinium oxycoccos, and of vascular plants in general. For dominant shrubs and all vascular species combined, N addition had no effect in the first two years, but frequencies increased with increasing N addition in 2013-2015. Pairwise year comparisons indicated a gradual change in plant species composition as the experiment progressed. Of the 21 pairwise comparisons between nominal N treatments, 18 were significant, indicating a clear influence of N addition on plant community composition. These results suggest that bogs that have persisted under very low ambient N deposition may be especially sensitive to increasing N deposition, in terms of plant species’ relative abundances and plant community composition.
