Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR): leaf SLA, C, N, P, Ca, delta-13C, delta-15N at peak biomass, 2017
The Carbon in Permafrost Experimental Heating Research (CiPEHR) project addresses the following questions: 1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C, that comprises the bulk of the soil C pool, influence ecosystem C loss?, and 3) How do winter and summer warming alone, and in combination, affect ecosystem C exchange? We are answering these questions using a combination of field and laboratory experiments to measure ecosystem carbon balance and radiocarbon isotope ratios at a warming experiment located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. This data set includes carbon (C) and nitrogen (N) elemental and isotope content in leaves collected from winter warming, summer warming, and control treatment plots at CiPEHR.
Eight Mile Lake Research Watershed, Thaw Gradient: leaf SLA, C, N, P, Ca, Mg, delta-13C, delta-15N at peak biomass, 2017
In this larger study, we are asking the question: Is old carbon that comprises the bulk of the soil organic matter pool released in response to thawing of permafrost? We are answering this question by using a combination of field and laboratory experiments to measure radiocarbon isotope ratios in soil organic matter, soil respiration, and dissolved organic carbon, in tundra ecosystems. The objective of these proposed measurements is to develop a mechanistic understanding of the SOM sources contributing to C losses following permafrost thawing. We are making these measurements at an established tundra field site near Healy, Alaska in the foothills of the Alaska Range. Field measurements center on a natural experiment where permafrost has been observed to warm and thaw over the past several decades. This area represents a gradient of sites each with a different degree of change due to permafrost thawing. As such, this area is unique for addressing questions at the time and spatial scales relevant for change in arctic ecosystems.
Soil Cation Exchange Capacity by the summation method CEC, Ca, Mg, K: Biodiversity II: Effects of Plant Biodiversity on Population and Ecosystem Processes
Biodiversity II (E120) is designed to determine how the number of plant species affects the dynamics of ecological processes at the population, community, and ecosystem levels. By experimentally manipulating the number of species and the kinds of species, the amount of plant growth and the change from year to year, that result can be examined. Plots are large (9m x 9m actively maintained) and well-replicated, allowing responses of plant pathogens, insect herbivores, seed predators, soil parameters, invasive plant species and other variables to also be studied. Plots were seeded in May 1994 to have 1, 2, 4, 8, or 16 species, with roughly 30 replicates of each diversity level. The species composition of each plot was chosen by random draw from a pool of 18 grassland perennials that included four warm-season (C4) grasses, four cool-season (C3) grasses, four legumes, four non-legume forbs, and two woody species. All species occur in monoculture allowing comparison of responses of each species in monoculture to combinations of these same species. The experiment was established in 1994 by the lead investigators David Tilman, Peter Reich, Johannes Knops, and David Wedin. Experiment 120 is similar to Experiment 123, but it uses larger plots to provide a large capacity for long-term subexperiments.
Foliar and sapwood nutritional and metabolic responses to Ca-treatment at the Hubbard Brook Experimental Forest, 2000 – 2015
Background Acidic deposition has caused a depletion of calcium (Ca) in the northeastern forest soils. One time application of wollastonite (CaSiO3 - 1.2 Mg ha-1 of Ca) was done at watershed 1 (WS1) of the Hubbard Brook Experimental Forest (HBEF) in 1999 to evaluate its effects on various functions of the HBEF ecosystem. This rate of application was intended to increase the existing base saturation of the soil from 10% to approximately 19%, and to increase the soil pH to the level that was estimated to exist ~50 years prior to treatment. More details on the treatment can be found at http://www.hubbardbrook.org/research/longterm/calcium/w1_overview/index.html. The overall objective of this study was to evaluate changes in foliar and sapwood metabolic parameters and microbial diversity as indicators of stress and overall health in trees exposed to Ca-supplementation. Raw data from Ca-treated WS1 are compared with WS3 (reference watershed) for cellular metabolites, exchangeable foliar chemistry (not totals) 2000-2015. These watersheds are in close proximity (less than 1.5 Km apart) with similar geology, temperature, soils, and overall climate. For more details see a list of references given below Ca-Supplementation-Metabolic Study (WS1 & along eastern edge of WS3) SUMMARY: The effects of Ca addition on foliar soluble (extractable in 5% HClO4) ions, chlorophyll, polyamines, and amino acids were studied in three hardwood species, namely sugar maple, yellow birch, and American beech. We further analyzed these effects in relation to elevation at Ca-supplemented WS1 and reference WS3 watersheds. During the earlier years foliar soluble Ca increased significantly in all species at mid and high elevations at Ca-supplemented WS1. This was accompanied by increases in soluble P, chlorophyll, and two amino acids, glutamate and glycine. A decrease in known metabolic indicators of physiological stress (i.e. the amino acids, arginine and γ-aminobutyric acid (GABA), and the diamine, pu
Red spruce foliar nutritional and metabolic responses to N, Ca, and N+Ca additions in a plot level study from Hubbard Brook Experimental Forest NH, Adirondack State Park, NY and Groton State Forest, VT from 1997-2000.
Plot Level Ca, N, Ca+N Study Background: Three mature red spruce (Picea rubens Sarg.) – balsam fir (Abies balsamea (L.) Mill.) stands with closed canopies from across the northeastern United States were selected to assess the effects of N and Ca additions on forest growth. These sites included Groton, VT (Groton State Forest), Big Moose Lake, NY (Adirondack State Park) and Watershed 9 in the Hubbard Brook Experimental Forest, NH. Site descriptions can be found in the pdf file included in this dataset. Full site descriptions have been published in Kulmatiski et al, 2007, Nitrogen and calcium additions increase forest growth in northeastern USA spruce–fir forests, Canadian Journal of Forest Research 37: 1574-1585. This publication also provides more in-depth site and soil descriptions. In 1992, three replicate 30 m by 30 m plots were randomly assigned to each of four treatment levels: control (control), Ca addition (Ca), N addition (N), or Ca + N addition (Ca + N) in NY and NH (for a total of 12 plots at each site). In VT, only control and Ca treatments were established due to limited space and research goals (for a total of 6 plots). Beginning in July 1992 through July 2000, N amendments (100 kilograms of NH4NO3-N per hectare per year), Ca amendments (80 kilograms of CaSO4-Ca plus 80 kilograms of CaCl2-Ca per hectare per year), and Ca + N (same dosage as separate applications) amendments were hand broadcast as commercial grade salts. Applications were made in June, July, and August to each plot in each year. SUMMARY: The main objectives of this study were to evaluate changes over time (1997-2000) in foliar metabolism of mature red spruce (Picea rubens Sarg.) trees in response to additions of nitrogen, Ca, or N +Ca supplementation. N was applied as NH4NO3 and Ca was applied as gypsum [CaSO4 .2H2O (2X) + CaCl2 .2H2O (1X)] and Ca + N treatment was a combination of both at the same concentrations Three sites received these treatments; Groton, VT (Groton State Forest), Bi

Infantry Shield (Pavise) ca. 1450
Bohemian, possibly Chomutov (now Czech Republic) Shields of this type were carried by crossbowmen and other foot soldiers in central Europe during the fifteenth century. They were often fitted with a prop to enable them to be freestanding. This example is painted in the center with a crown surmounted by three ostrich feathers, a badge of the kings of Bohemia. Below this is the letter Y on a radiant cloud, possibly the monogram for Yhesus (Jesus). At the top is the coat of arms of the Saxon city of Zwickau (a red shield with three white swans), which was added to the shield at a later date. Now in Metropolitian Museum in New York Source: Objaverse 1.0 / Sketchfab

«Recepción de Cristóbal de Morales en Valladolid (ca. 1530-1550): una opinión, una tablatura, un inventario y el manuscrito 5 (E-V5)». Anuario musical 78 (2023), pp. 31-57.
<p>Abstract;<br>This paper deals with the reception of Cristóbal de Morales`s<br>music in the vibrant city of Valladolid during the 1530s and 1540s,<br>a period that covers the years before his establishment in Rome<br>(1535) and those immediately after his definitive return to Spain<br>(1545). It is supported by four primary evidences: the assessment of<br>the author by Professor Cristóbal de Villalón, an intabulation, an<br>inventory made in 1547 in the Collegiate Church of Valladolid, and<br>the unique Manuscript 5 (E-V5). A detailed study of this «white<br>book» has made it possible to offer its complete and complex structure,<br>a piece of information which, combined with that provided by<br>the inventory and other documentary sources, allows us to better<br>understand its chronology and functionality. They also allow us to<br>present the person responsible for copying it, an essential mediator<br>in the dissemination of the music of Cristóbal de Morales, at least in<br>the Valladolid Collegiate Church.</p>
