title: Meta-analysis of marine nutrient-enrichment experiments: systematic variation in the magnitude of nutrient limitation

description: Nutrient bioassay experiments have been performed in many marine and estuarine environments around the world. Although protocols have been relatively uniform, these experiments have yielded mixed results, implicating nitrogen, phosphorus, silica, iron, and several other elements as factors limiting phytoplankton growth. Meta-analysis has the potential to explain much of this variation by exploring the relationship between the magnitude of limitation and various environmental characteristics. We quantified limitation with a simple metric,Δr, that estimates the change in the per unit growth rate of phytoplankton directly attributable to addition of a specific nutrient, such as nitrogen, iron, or phosphorus. Preliminary analyses indicated that experiments lasting 1 d exhibited time lags in the numerical response of phytoplankton to nutrient addition, while experiments lasting&gt;7 d confounded nutrient limitation with processes such as increased grazing or depletion of other nutrients. Thus, we restricted the meta-analysis to results from 2-7 d experiments. These analyses showed that phosphorus enrichment usually had little impact on phytoplankton growth, while enrichments of nitrogen and iron increased phytoplankton growth by 0.1-0.3 d-1. Nutrient limitation due to N, P, and Fe varied significantly among sites. Nitrogen limitation was greatest in nearshore, nutrient-polluted, and temperate environments (where most experiments have been performed), while phosphorus and iron limitation were strongest in open ocean, unpolluted, and tropical ecosystems, or those receiving pollutants with high N:P ratios. Because phosphorus-enrichment studies have been most often performed in relatively polluted coastal waters, the possible role of phosphorus in limiting primary production in unpolluted oceanic systems may have been underestimated.Examining heterogeneity of responses of different systems to experiments is a valuable application of meta-analysis and can facilitate the development of new ecological insights.

title: Monthly precipitation data at Santa Rita Experimental Range, Arizona

description: The file contains monthly precipitation measurements collected from 75 gauges at the Santa Rita Experimental Range. Of these 75 gauges, 28 are currently being monitored and 47 have been discontinued. Some gauges had measurements recorded under more than one name, but all data are entered under the most recent name. Precipitation amounts are recorded in 100ths of inches; two decimal places are assumed (e.g., 125 = 1.25 inches). A zero indicates that no precipitation occurred that month. A value of -9999 indicates missing or unavailable data. The sources of file data were original handwritten records and previously digitized data. In cases of discrepancy the original records were considered to be the ultimate authority.

title: A Comparison of Vegetation Responses to Grazing Yearlong, in the Growing Season, and in the Dormant Season on Low-Value Semidesert Grass-Shrub Ranges in Southern Arizona - Production data for 1957-1966 and 1970

description: The file prod09.xls contains net aboveground production data for perennial and annual grasses for USFS Study FSRM 1706-09. A copy of the Study Plan may be obtained at http://ag.arizona.edu/SRER/study09/study09.txt. Measurements were taken annually from 1957-1966 and in 1970 on 12 pairs of sample plots in each of 6 pastures. Each pair of plots was located at one of three distances from water and on one of two kinds of soil. Each pasture was subjected to one of three livestock grazing treatments. Pastures 3 and 5N were grazed during the winter dormant season (approximately November through April). Pastures 5S and 12B were grazed during the summer growing season (approximately May through October). Pastures 2N and 6B were grazed yearlong. Two permanent 100-ft. line transects were established at each plot location. One transect in each plot was a control, but all mesquite (Prosopis velutina) within 50 ft. of the other was killed. Herbage production was estimated in autumn as soon as possible after the end of the summer growing season. Estimates were on two 8x24 ft. subplots centered over each transect (with long axis along the transect). Production estimates were adjusted for utilization where necessary. Field weights were estimated in grams, then converted to dry weights using factors developed from double sampling. Dry weights were then converted into air-dry pounds per acre (to the nearest pound). Perennial grass data is recorded by genus or species. All species of annual grasses were combined into one measurement. Sources of data were original field data sheets and a printout of previously digitized data. Taxa were recorded separately to the species level in most cases and sometimes to the genus level only. The OTHERPG code refers to unidentified perennial grass species; ANNGRASS to all annual grass species. When measurements are entered for OTHERPG, the species and genera to which they refer are not consistent. In this study ARIS refers to the Aristida genus (specifically tall threeawns). A value of -9999 in a field means that no data were available because a reading was not made for that date. A value of -99 in a field means that the datum is unknown. Due to the method used to calculate air-dry pounds per acre, a zero entry may have one of two meanings: 1) The species did not occur at all in the plots, or 2) The species occurred in a quantity too small to round up to one pound per acre. The significance of a particular zero entry cannot be inferred from the table; field sheet review would be necessary.

title: A Demonstration to Determine the Feasibility of Achieving Rotation-Deferred Grazing within a Single Pasture by Controlling Access to Water - Production data for 1959-1966

description: The file contains net aboveground production data for perennial and annual grasses for USFS Study 1706-15. A copy of the Study Plan may be downloaded at http://ag.arizona.edu/SRER/study15/study15.txt. Measurements were taken annually from 1959-1966 in plots located along permanent line transects in two pastures. Transects were established at distances of 100, 200, 300, 400, and 500 yards from each of five water sources. Fifty transects (two sets of five at each water source) were measured in pasture 6A. Ten transects (two sets of five at one water source shared with pasture 6A) were measured in pasture 6B. A water-rotation schedule in pasture 6A specified only one water source to be open at a time. The water source for pasture 6B was open continuously. The study area was grazed yearlong by cattle. Herbage production was estimated to the nearest gram each autumn using double sampling. Field weights were estimated on five permanent 9.6x1 ft. plots and on one temporary plot per transect. Herbage on temporary plots was clipped and weighed to calculate a factor for adjusting ocular estimates. Dry weights of clipped herbage provided a moisture correction factor. Field weights from the permanent plots were converted to grams per 96 sq. ft. plot. Grams per 96 sq. ft. plot were converted to the nearest 0.1 air-dry pound per acre by applying the factors. In this file air-dry pounds per acre amounts are truncated at the decimal point except for amounts of 0.1-0.9, which are recorded as one pound per acre. Totals calculated from file values will generally be lower than ones calculated from field data due to truncation. Taxa were recorded separately to the species level in most cases and sometimes to the genus level only. The OTHERPG code refers to unidentified perennial grass species; ANNGRASS to all annual grass species. Sources of data were the original field data sheets with the following exceptions: 1) Air-dry pounds per acre had not been calculated for 1959 so these amounts were calculated by applying the factors to total grams on the field data sheets. 2) Air-dry pounds per acre had not been calculated for 1960-1961 so these amounts were calculated by applying the factors to grams per 96 sq. ft. plot on the field data sheets.

The water source for pasture 6B was open continuously. The study area was grazed yearlong by cattle. Cover was measured in late summer or autumn in units of 0.01 ft. Perennial grass was recorded as basal intercept; i.e., length of live root crown portion of tuft at ground level. Shrub cover was recorded as the entire live crown intercept excluding conspicuous openings or areas of dead crown. Taxa were recorded separately to the species level in most cases and sometimes to the genus level only. The code OTHSHRUB refers to unidentified shrub species. Sources of data were the original field data sheets.
