Coyote Scat Surveys in Chihuahuan Desert Grassland and Shrubland Sites, Spring, Summer and Fall at the Sevilleta National Wildlife Refuge, New Mexico (2008-2009)

This data set contains information regarding carnivore scat surveys that were performed at sites in grama grassland and both creosote and mesquite shrubland habitats at the Sevilleta NWR. A total of nine surveys were carried out along road-based transects, each of which is a mile long, during one season in 2008 (June-July) and three seasons in 2009: spring (April-May), summer (July-August), and fall (October-November). There were 10 transects in grassland areas and 10 in shrubland areas in 2008. All 20 transects, as well as two additional transects in grassland areas, were surveyed in 2009. For more information on the structure of the vegetation surrounding these road based transects, see the "Vegetation surveys in grassland and shrubland sites that are associated with coyote scat surveys at the Sevilleta NWR, 2008-2009" data set. Scat samples were identified in the field and collected for genetic and stable carbon isotope analysis. Field recorded variables include: scat freshness, maximum diameter, length, and GPS coordinates, as well as the field-based species identification for the sample. Information on the lab based species and individual identification results are also presented.This data was collected in order to obtain information on the size and feeding ecology of the coyote populations in grassland vs. shrubland habitats in three seasons (spring, summer and fall) and two years (2008 and 2009) at the Sevilleta NWR. A mark recapture analysis can be performed on the data from 2009 since two surveys were carried out for each scat transect in each of the three seasons and coyote scats were run through a genetic analysis to determine individual identity of the coyotes. A rough assessment of coyote habitat use can also be performed using the individual identity and coyote scat location information. Future isotope analysis will indicate whether the base of the food chain is C4 (grass) vs. C3 (shrubs) plants in grassland vs. shrubland habitats in each of the three

Snakeweed Patch Vegetation Quad Data at the Sevilleta National Wildlife Refuge, NM (1984, 1996)

In 1984, a research project was initiated on a relatively small disturbance patch just south of Deep Well. This disturbance was thought to be the result of an old praire dog town, probably dating back to when a nearby ranch was active, and a lot of old mammal mounds remained in the disturbed area. One of the things that made the disturbance patch particularily noticeable was the lush growth of snakeweed (Gutierrezia sarothrae) within the patch. This prompted the designation of the disturbance patch as the "snakeweed patch" or "Gutierrezia patch." In addition, there was an obvious increase in bare ground and a shift in vegetation composition across the patch boundary. The dominant vegetation was not consistent around the boundary, with a marked dominance of black grama on the west side of the plot and a blue/black grama mix on the other three sides. To obtain information on the cause and/or effect of this disturbance, a survey of the soil and vegetation was performed. This database contains information collected during the vegetation monitoring that was done on the plot in 1984, as well as a follow-up measurement done in 1996. By 1996, virtually all of the snakeweed had died due to a dry period.

Gunnison's Prairie Dog Restoration Experiment (GPDREx): Population Dynamics within Grasslands at the Sevilleta National Widlife Refuge, New Mexico

Prairie dogs (Cynomys spp.) are burrowing rodents considered to be ecosystem engineers and keystone species of the central grasslands of North America. Yet, prairie dog populations have declined by an estimated 98% throughout their historic range. This dramatic decline has resulted in the widespread loss of their important ecological role throughout this grassland system. The 92,060 ha Sevilleta NWR in central New Mexico includes more than 54,000 ha of native grassland. Gunnison’s prairie dogs (C. gunnisoni) were reported to occupy ~15,000 ha of what is now the SNWR during the 1960’s, prior to their systematic eradication. In 2010, we collaborated with local agencies and conservation organizations to restore the functional role of prairie dogs to the grassland system. Gunnison’s prairie dogs were reintroduced to a site that was occupied by prairie dogs 40 years ago. This work is part of a larger, long-term study where we are studying the ecological effects of prairie dogs as they re-colonize the grassland ecosystem.

Mega-Monsoon Experiment (MegaME) Vegetation Sampling Data from the Sevilleta National Wildlife Refuge, New Mexico

Shrub encroachment is a global phenomenon. Both the causes and consequences of shrub encroachment vary regionally and globally. In the southwestern US a common native C3 shrub species, creosotebush, has invaded millions of hectares of arid and semi-arid C4-dominated grassland. At the Sevilleta LTER site, it appears that the grassland-shrubland ecotone is relatively stable, but infill by creosotebush continues to occur. The consequences of shrub encroachment have been and continue to be carefully documented, but the ecological drivers of shrub encroachment in the southwestern US are not well known. One key factor that may promote shrub encroachment is grazing by domestic livestock. However, multiple environmental drivers have changed over the 150 years during which shrub expansion has occurred through the southwestern US. Temperatures are warmer, atmospheric CO2 has increased, drought and rainy cycles have occurred, and grazing pressure has decreased. From our prior research we know that prolonged drought greatly reduces the abundance of native grasses while having limited impact on the abundance of creosotebush in the grass-shrub ecotone. So once established, creosotebush populations are persistent and resistant to climate cycles. We also know that creosotebush seedlings tend to appear primarily when rainfall during the summer monsoon is well above average. However, high rainfall years also stimulate the growth of the dominant grasses creating a competitive environment that may not favor seedling establishment and survival. The purpose of the Mega-Monsoon Experiment (MegaME) is twofold. First, this experiment will determine if high rainfall years coupled with (simulated) grazing promote the establishment and growth of creosotebush seedlings in the grassland-shrubland ecotone at Sevilleta, thus promoting infill and expansion of creosotebush into native grassland. Second, MegaME will determine if a sequence of wet summer monsoons will promote the establishment and gro

Ecosystem-Scale Rainfall Manipulation in a Piñon-Juniper Forest at the Sevilleta National Wildlife Refuge, New Mexico: Meteorological Data (2006-2013 )

Climate models predict that water limited regions around the world will become drier and warmer in the near future, including southwestern North America. We developed a large-scale experimental system that allows testing of the ecosystem impacts of precipitation changes. Four treatments were applied to 1600 m2 plots (40 m × 40 m), each with three replicates in a piñon pine (Pinus edulis) and juniper (Juniper monosperma) ecosystem. These species have extensive root systems, requiring large-scale manipulation to effectively alter soil water availability. Treatments consisted of: 1) irrigation plots that receive supplemental water additions, 2) drought plots that receive 55% of ambient rainfall, 3) cover-control plots that receive ambient precipitation, but allow determination of treatment infrastructure artifacts, and 4) ambient control plots. Our drought structures effectively reduced soil water potential and volumetric water content compared to the ambient, cover-control, and water addition plots. Drought and cover control plots experienced an average increase in maximum soil and air temperature at ground level of 1-4° C during the growing season compared to ambient plots, and concurrent short-term diurnal increases in maximum air temperature were also observed directly above and below plastic structures. Our drought and irrigation treatments significantly influenced tree predawn water potential, sap-flow, and net photosynthesis, with drought treatment trees exhibiting significant decreases in physiological function compared to ambient and irrigated trees. Supplemental irrigation resulted in a significant increase in both plant water potential and xylem sap-flow compared to trees in the other treatments. This experimental design effectively allows manipulation of plant water stress at the ecosystem scale, permits a wide range of drought conditions, and provides prolonged drought conditions comparable to historical droughts in the past – drought events for which wide

Biannual Juniper Branch Demography Study at the Sevilleta National Wildlife Refuge, New Mexico (1989-1993)

This project was designed to investigate the response of plant growth and reproduction to short- and long-term variation in biotic and abiotic environmental variables. Several perennial taxa, including tree (Juniperus monsperma and Pinus edulis), shrub (Larrea tridentata) and bunch grasses (Oryzopsis hymenoides (now Achnaterum hymenoides) and Sporobolus contractus) species, were monitored at 1-3 sites differing in elevation and topography as well as edaphic variables and annual precipitation. The sites represented optimal or marginal/transitional zones for particular species. Demographic measurements were made biannually, after the 'wet' (fall) and 'dry' (spring) seasons. For tree and shrub species, estimates of growth and reproduction were based on branch demography, with ten branch tips from 10-20 individuals per species per site repeatedly measured from 1989-1993. For J. monsperma, P. edulis and L. tridentata, vegetative growth (i.e., branch growth) as well as reproduction were monitored. Additional measurements included needle length for P. edulis and leaf production, leaf size and branchlet production for L. tridentata. For grasses, basal diameter, leaf length and reproduction were monitored for 100 individuals per species per site. This project, SEV028, contains only data on juniper branch demography. Data on other variables and species is contained in SEV006, SEV024, SEV025, SEV026, and SEV027.

Ground Arthropod Community Survey in Grassland, Shrubland, and Woodland at the Sevilleta National Wildlife Refuge, New Mexico (1992-2004)

This data set contains records for the numbers of selected groups of ground-dwelling arthropod species and individuals collected from pitfall traps at 4 sites on the Sevilleta NWR, including creotostebush shrubland, both black and blue grama grasslands, and a pinyon/juniper woodland. Data collections begin in May of 1989, and are represented by subsequent sample collections every 2 months. One site (Goat Draw/Cerro Montosa) was discontinued in 2001, and a new site (Blue Grama) was initiated . Only three sites, creosotebush, black grama, and blue grama were continued between 2001-2004.

Monsoon Rainfall Manipulation Experiment (MRME) Meteorology Data from a Chihuahuan Desert Grassland at the Sevilleta National Wildlife Refuge, New Mexico

The Monsoon Rainfall Manipulation Experiment (MRME) is to understand changes in ecosystem structure and function of a semiarid grassland caused by increased precipitation variability, which alters the pulses of soil moisture that drive primary productivity, community composition, and ecosystem functioning. The overarching hypothesis being tested is that changes in event size and variability will alter grassland productivity, ecosystem processes, and plant community dynamics. In particular, we predict that many small events will increase soil CO2 effluxes by stimulating microbial processes but not plant growth, whereas a small number of large events will increase aboveground NPP and soil respiration by providing sufficient deep soil moisture to sustain plant growth for longer periods of time during the summer monsoon. Â These data were collected at a meteorological station at the Monsoon Site.

Warming-El Nino-Nitrogen Deposition Experiment (WENNDEx): Soil Temperature, Moisture, and Carbon Dioxide Data from the Sevilleta National Wildlife Refuge, New Mexico

Humans are creating significant global environmental change, including shifts in climate, increased nitrogen (N) deposition, and the facilitation of species invasions. A multi-factorial field experiment is being performed in an arid grassland within the Sevilleta National Wildlife Refuge (NWR) to simulate increased nighttime temperature, higher N deposition, and heightened El Nino frequency (which increases winter precipitation by an average of 50%). The purpose of the experiment is to better understand the potential effects of environmental drivers on grassland community composition, aboveground net primary production and soil respiration. The focus is on the response of two dominant grasses (Bouteloua gracilis and B eriopoda), in an ecotone near their range margins and thus these species may be particularly susceptible to global environmental change. It is hypothesized that warmer summer temperatures and increased evaporation will favor growth of black grama (Bouteloua eriopoda), a desert grass, but that increased winter precipitation and/or available nitrogen will favor the growth of blue grama (Bouteloua gracilis), a shortgrass prairie species. Treatment effects on limiting resources (soil moisture, nitrogen availability, species abundance, and net primary production (NPP) are all being measured to determine the interactive effects of key global change drivers on arid grassland plant community dynamics and ecosystem processes. This dataset shows values of soil moisture, soil temperature, and the CO2 flux of the amount of CO2 that has moved from soil to air. On 4 August 2009 lightning ignited a ~3300 ha wildfire that burned through the experiment and its surroundings. Because desert grassland fires are patchy, not all of the replicate plots burned in the wildfire. Therefore, seven days after the wildfire was extinguished, the Sevilleta NWR Fire Crew thoroughly burned the remaining plots allowing us to assess experimentally the effects of interactions among multip

Monsoon Rainfall Manipulation Experiment (MRME): Soil Nitrogen Data from the Sevilleta National Wildlife Refuge, New Mexico (2007 - 2020)

The Monsoon Rainfall Manipulation Experiment (MRME) is designed to understand changes in ecosystem structure and function of a semiarid grassland caused by increased precipitation variability, by altering rainfall pulses, and thus soil moisture, that drive primary productivity, community composition, and ecosystem functioning. The overarching hypothesis being tested is that changes in event size and frequency will alter grassland productivity, ecosystem processes, and plant community dynamics. Treatments include (1) a monthly addition of 20 mm of rain in addition to ambient, and a weekly addition of 5 mm of rain in addition to ambient during the months of July, August and September. We predict that soil N availability with interact with rainfall event size to alter net primary productivity during the summer monsoon. Specifically, productivity will be higher on fertilized relative to control plots, and productivity will be highest on N addition plots in treatments with a small number of large events because these events infiltrate deeper and soil moisture is available longer following large compared to small events.

Effects of Altered Precipitation on Biological Soil Crusts, Fungi, and Soil Nitrogen Availability at the Monsoon Rainfall Manipulation Experiment (MRME) in the Sevilleta National Wildlife Refuge, New Mexico (2016)

Microbial activity in drylands is mediated by the magnitude and frequency of growing season rain events that will shift as climate change progresses. Nitrogen is often co-limiting with water availability to dryland plants, and thus we investigated how microbes important to the nitrogen (N) cycle and soil N availability varied temporally and spatially in the context of a long-term rainfall variability experiment in the northern Chihuahuan Desert. Specifically, we assessed biological soil crust (biocrust) chlorophyll content, fungal abundance, and inorganic N in soils adjacent to individuals of the grassland foundation species, Bouteloua eriopoda, and in the unvegetated interspace at multiple time points associated with an experimental monsoon rain treatment. Treatments included small weekly (5 mm) or large monthly (20 mm) rain events, which had been applied during the summer monsoon for nine years prior to our sampling. Additionally, we evaluated target plant C:N ratios and added 15 N-glutamate to biocrusts to determine potential for nutrient transport to B. eriopoda. Biocrust chlorophyll was up to 67% higher in the small weekly or large monthly rainfall regimes compared to ambient controls. Fungal biomass was 57% lower in soil interspaces than adjacent to plants but did not respond to rainfall regime treatments. Ammonium and nitrate concentrations near plants declined through the sampling period but varied little in soil interspaces. There was limited movement of 15 N from interspace biocrusts to leaves but high 15 N retention in the soils even after additional ambient and experimental rain events. Plant C:N ratio was unaffected by rainfall treatments. The long-term alteration in rainfall regime in this experiment did not change how short-term microbial abundance or N availability responded to the magnitude or frequency of events, suggesting a limited response of N availability to future climate change.

The water balance vegetation plots were part of a larger water balance monitoring project at the Sevilleta LTER. The plots were designed to measure the percent cover of photosynthetic/transpiring (green) plant species at specific sites where time domain reflectometry (TDR) probes and weather stations were already installed. In 1995, there were three sites (Field Station, Deep Well and Rio Salado). A 30m x 30m plot was installed at each site, and collection of vegetation data commenced in July 1995. Percent cover (green) and species identities were recorded monthly at a representative sample of 1m square quadrats within each plot.

Mesocosm (Marsh Organ) experiment at Blackwater National Wildlife Refuge, MD, 2012

This experiment examines the effects of tidal inundation on the growth of salt marsh vegetation. We measured the response of plants to disturbance across a gradient in inundation times by transplanting tussocks of Schoenoplectus americanus into mesocosms of different elevation. The mesocosms were arranged into structures commonly described as ï¿½marsh organsï¿½. Here we utilize two marsh organs each containing 54 mesocosms constructed of 6-inch diameter (0.0182, m2) polyvinyl chloride pipe, arranged into nine rows containing six pipes of identical elevation. We conducted the experiment in a large brackish marsh on the Atlantic Coast of North America. The study site is adjacent to the Blackwater River, a tributary of the Chesapeake Bay (Maryland, USA) (Blackwater, 38.40ï¿½N, 76.07ï¿½W). Changes in water level are primarily driven by meteorological events, with mean astronomical tides of <0.25â€‰m. Long-term porewater salinities average 10â€‰p.p.t. within the marsh soil, and intertidal vegetation is dominated by Schoenoplectus americanus and Spartina patens.

Treatment of American National Archives Records of World War II Prisoners of War (0326).

NARA PoW Data W.D. A.G.O. FORM NO. 0326. This deposit contains a dataset relating to persons interned between December 7, 1941 and November 19, 1946, which has been enhanced to make it more accessible to scientists. It is based on information from the U.S. National Archives and Records Administration (NARA), which is unrestricted and available at <a href="https://aad.archives.gov/aad/series-description.jsp?s=644&popup=Y">https://aad.archives.gov/aad/series-description.jsp?s=644&popup=Y</a>, and informs this summary. The NARA 'series' is part of Record Group 389: Records of the Office of the Provost Marshal General. It identifies 79 'places of capture' globally "Using copies of reports from the International Committee of the Red Cross ...". The Scope & Content Note states: "This series has information about U.S. military officers and soldiers and U.S. and some Allied civilians who were prisoners of war and internees. The record for each prisoner provides serial number, personal name, branch of service or civilian status, grade, date reported, race, state of residence, type of organization, parent unit number and type, place of capture (theater of war), source of report, status, detaining power, and prisoner of war or civilian internee camp site. Records of prisoners of the Japanese who died also document whether the prisoner was on a Japanese ship that sank or if he or she died during transport from the Philippine Islands to Japan. There are no records for some prisoners of war whose names appear in the lists or cables transmitted to the Office of the Provost Marshal General by the International Committee of the Red Cross." The U.S. War Department used punched cards to manage this information, although "The punch card records were transferred to NARA with virtually no agency documentation." According to the Custodial History Note: "The U.S. Army transferred punch card records of World War II prisoners of war (POWs) to NARA as a unique series in its 1959 transfer of all of the U.S. Army's Departmental Archives. In 1978 the Veterans Administration borrowed most of the punch card records of repatriated U.S. military personnel for a study of Repatriated U.S. Military Prisoners of War, migrated the data on almost all of the borrowed cards to an electronic format and returned the punch cards and two electronic records data files to NARA. In 1995 NARA migrated the data from almost all of the remaining punch card records to an electronic format and has subsequently preserved all of the records in a single data file." It is evident that the organization of this data file assumes access to other information, also accessible in CSV files in the series, in order to interpret detailed information, such as branch of service, grade, parent unit number and detaining power. For example, records appear in the following format: <pre><code class="language-bash">O&745255ABDALLAH EDWARD A 2 LT G1AC 200803413223003620O7222094171035 32214872ABDALLAH JOSEPH T CPL 61INF10230241231100157069802075181087 36336867ABDAY JOSEPH C PVT 81INF10170231611100168069516075181004 </code></pre> constituting a serial number, then a name, then a textual code for rank; followed by a string, (starting G1AC on the first line) which encodes the remaining information. For example, the first digit (G) can be looked up in cl_1279.csv to decode ‘2nd lieutenant’, corroborating in this case the appearance of '2 LT. 'AC' indicates 'armofservicecode: AIR CORPS', but less obviously, 'detainingpower: Germany'; 'race: White' and 'theater: European Theater: Germany'. This single line is the entirety of the information provided per person instance by the NARA series. Users of this potentially valuable resource must develop automation in order to be able to search and employ it effectively; no such tools or specification from which software might be developed immediately is provided. Significantly, this task is hampered by evidence of corruption of the some of the information, which may be due solely to the digitization process mentioned above being applied to the paper records, but possibly with subsequent contribution of fixity effects. NARA documentation does not refer to data integrity issues and, especially since the dataset which NARA provides is large, it may only be during development of automation to employ the series that such issues are discovered. Examples of problems include substitution of characters, such as 'O' replacing '0' and vice-versa; '}' replacing '3' and '&' replacing '8', or less obviously 'L' mis-recognized as '-' and 'II' replacing 'H'. <pre><code class="language-bash">12138003 AREY GERALD J S SG 41AC 2002064123S55}340069802055181033</code></pre> Ideally, access to high resolution scans of the paper documents could be used to address these issues, or external documents. However, checking for completeness of each of the components of a person record enables detection of compromised entries and, where character substitution affects decoding of key information, other contextual information is often available to validate decoding such strings with these characters re-substituted. The larger percentage of strings which already decode plausibly without intervention do not contain incidences of such characters (so there is strong evidence that they are invalid in particular positions. Unfortunately, there is a proportion of digital records with more severe corruption which cannot be addressed without access to scanned imagery of the paper records, for example: <pre><code class="language-bash">O&557875ANDREW THOMAS A 2 LT G1AC 2011094115 70140 6881276AFTEWICZ EDWARD L PVT 81INF10150231321100135069508065181004 6 APLIN -OR-& - 3 1INF102 1 1 0 1 1</code></pre> As of the initial date of this deposit is anticipated that such access will be possible to support further work on this series. The dataset in this deposit does not contain records for which decoding is compromised to the extent that information to populate a basic person schema is incomplete. However, although 36,791 of the 143,374 person records in the NARA series were found to be compromised in some way, 19,624 of those have been substantially decoded and/or repaired and further work is being undertaken to both improve decoding of the 126,207 available here and to retrieve others among the 17,167 which are currently inaccessible. This dataset has been enhanced to present the original NARA 'single data file' as a JSON resource which is more accessible for search and analysis, since each record is document-oriented (containing labels and values for each field, together with provenance information) for example: <pre><code class="language-json">{ "$schema": "https://schemata.hasdai.org/historic-persons/historic-person-entry-v0.0.2.json", "location": [ { "association": "military service", "transcription": "European Theater: Germany" }, { "association": "interred", "transcription": "Stalag 2D Stargard Pomerania, Prussia 53-15" } ], "name": { "familyname": "AARON", "givenname": "JACK", "rank": "SGT", "transcription": "AARON JACK" }, "set": { "id": "https://persons.freizo.org/export/pow/1.0.0", "partof": "10.5281/zenodo.3565392", "title": "WDAGO-0326" }, "source": { "type": "data file" } },</code></pre> The schema employed here serves a specific purpose, in addition to on-going work identifying and correcting errors in the NARA data: it supports work to discover other instances of persons appearing in this NARA series 0326, which also appear in external documentation. For example, in a separate collaborative project with Europa Institute at the University of Basel, a benchmark dataset has been produced based on listings of foreign residents in the Asian Directories and Chronicles, which forms a deposit at <a href="https://doi.org/10.5281/zenodo.2580997">10.5281/zenodo.2580997</a> and employs a compatible schema for the purpose of efficient comparison with this and other datasets. Other schemata could be employed for different purposes—leading to alternate datasets, all derived from series 0326. The full extent of information currently decoded from NARA series 0326 is presented at <a href="https://pow.freizo.org/">https://pow.freizo.org/</a> which provides search facilities by person name, plus interactive filters for person rank, service and theater of conflict.

The use of ancient DNA from sediment as a viable measure of Quaternary biodiversity within the Brecon Beacons National Park: a preliminary study

Contains 3 files. <ul> <li>One spreadsheet containing processed sequences -SM1_results_spreadsheets</li> <li>The other two containing Read 1 and Read 2 of the raw sequences (fastq).</li> </ul> Abstract A major challenge in the study of Quaternary environments is the variable preservation of paleoenvironmental evidence at many locations. Using ancient DNA from sediment cores (sedaDNA) allows the reconstruction of past biodiversity patterns at locations where traditional techniques often only reveal a partial picture. To test the feasibility of this approach, we analysed a sediment core from a peat bog, Traeth Mawr, in the Brecon Beacons National Park. Plant DNA was extracted and subjected to DNA metabarcoding, combining the use of universal PCR primers with Next-Generation Sequencing, to analyse a 7-143bp segment of the chloroplast trnL gene in five temporally separated sections of the core. Pollen analyses, from sections of the core, provide a comparison between the sedaDNA results and more traditional methods for studying the paleoenvironment. Partial reconstruction of past environmental variation was possible with the recovery of 113,682  DNA sequences representing six plant families, adding complementary results to traditional pollen analysis. This study is the first in the UK to successfully report the sequencing of ancient plant DNA from terrestrial sediments (currently a peat bog) using a DNA metabarcoding approach and exemplifies a promising area of research for addressing a range of questions about Quaternary environmental change.
