Monitoring of vegetation and fire in Florida scrub, flatwoods, and wet prairie in south-central Florida from 1977-2015
This data package is comprised of three datasets all pertaining to the impacts of prescribed fires and wildfires on vegetation at 11 permanent transect sites over nearly four decades at Archbold Biological Station (ABS) in south-central Florida. Data were collected between 1977 to 2015 in wet prairies, flatwoods, oak scrub, rosemary scrub, and hickory scrub. The first dataset, cover_data, contains year and month of sampling at a given transect site, the vegetation association type, burn unit, and the percentage cover data for sampled species and bare ground. The second dataset, fire_occurrence, includes the dates of each fire that impacted each transect site, the burn unit of the transect, and the percentage of transect burned. The third dataset, species_information, includes the scientific name, common name, plant family, and nativity of each sampled species. A fourth unpublished dataset provides the GPS locations for all the aluminum posts that mark each of the 11 transects. These data are available from the Archbold data manager. Below we summarize the setup and data collected for each dataset. Cover_data: We determined the percentage cover (i.e., dominance) of each encountered species at 11 vegetation stands including two wet prairies (WS20, WS21), three flatwoods (WS30, WS42, WSP1), and six Florida scrub associations including four oak scrubs (WS26, WSP2, WS24, WS25, the latter two include areas of rosemary scrub), a rosemary scrub (WS27), and a hickory scrub (WS29). Each stand was sampled at selected times, ranging from five to as many as 12 repeated samplings, during the 38-yr period beginning in 1977 and continuing to 2015. Stands were sampled during January (mid-way during the winter dry season) except for sampling four stands in May 1977 and eight stands in July 1977 to document short-term 4-month and 6-month vegetation recovery following the initial January 1977 prescription burn. At each permanently marked transect site, we sampled 200 m using two parall
FIG. 5 in Variation in Flatwoods Salamander Survival Is Unrelated to Temperature and Rainfall
FIG. 5. Size-dependent survival estimates for Reticulated Flatwoods Salamanders by year. Body size reflects snout–vent length (SVL) in mm. The shaded regions indicate the 95% credible intervals.
FIG. 3 in Variation in Flatwoods Salamander Survival Is Unrelated to Temperature and Rainfall
FIG. 3. Detection probability within each breading season as it relates to rainfall in the previous summer. Kendall's tau was used to determine the strength of the correlation between the variables (Kendall's t ¼ 0.57, P ¼ 0.03). No other correlations were found between environmental conditions and parameters of interest.
FIG. 4 in Variation in Flatwoods Salamander Survival Is Unrelated to Temperature and Rainfall
FIG. 4. Size-dependent survival estimates for Reticulated Flatwoods Salamanders averaged across years. Body size reflects snout–vent length (SVL) in mm. The shaded region indicates the 95% credible interval.
FIG. 2 in Variation in Flatwoods Salamander Survival Is Unrelated to Temperature and Rainfall
FIG. 2. Body size distributions for males (M), females (F), and individuals of unknown sex (U). Sizes are snout–vent length (SVL) in millimeters. Points represent the raw data points; the center lines show mean, 75%, and 95% confidence intervals; and the shaded region is an approximate density. The average size of females was larger than males (t ¼ 13.4, df ¼ 247, P, 0.001) and individuals of unknown sex (t ¼ 13.4, df ¼ 320, P, 0.001), and the average size of males was larger than individuals of unknown sex (t ¼ 4.1, df ¼ 272, P, 0.001).
FIG. 1 in Variation in Flatwoods Salamander Survival Is Unrelated to Temperature and Rainfall
FIG. 1. Body size distributions for Reticulated Flatwoods Salamanders by year. Sizes are snout–vent length (SVL) in millimeters. Points represent the raw data points; the center lines show mean, 75%, and 95% confidence intervals; and the shaded region is an approximate density.
Larval A. bishopi microsatellite data from: Metapopulation genetics of endangered reticulated flatwoods salamanders (Ambystoma bishopi) in a dynamic and fragmented landscape
<p>The dataset consists of 9 microsatellite markers used to analyze reticulated flatwoods salamanders' (<em>Ambystoma bishopi</em>) population structure on Eglin AFB. Samples came from various breeding ponds and allele sizes were scored using GeneMapper (GeneMapper v4.0; Applied Biosystems). Data was collected via allele scoring in GeneMapper by two independent researchers. Allele sizes for each individual have been re-formatted for various programs using the microsatellite Add-in in Excel as well as by using the GenAlEx extension in Excel. </p>

Table 5 in Guide to the Vascular Flora of the Savannas and Flatwoods of Shaken Creek Preserve and Vicinity (Pender & Onslow Counties, North Carolina, U. S. A.)
<p>Table 5. Summary of vascular plant taxa collected or reported from savannas, flatwoods, or sandhills in Shaken Creek Preserve or the vicinity (i.e., in Sandy Run and/or within a 2-mile radius of Shaken Creek Preserve). The first number in each three-number series indicates the number of taxa collected or reported from Shaken Creek Preserve. The second number in each series indicates the number of additional taxa collected or reported from the vicinity of, but not in, Shaken Creek Preserve. The third number in each series, which appears in parentheses, is the sum of the preceding two numbers and indicates the total number of taxa collected or reported from either Shaken Creek Preserve or the vicinity. (The lone exotic taxon is Pinus elliottii Engelm. var. elliottii, which was planted by a timber company in a flatwoods in Shaken Creek Preserve prior to the site’s purchase by The Nature Conservancy.)</p><table><tbody><tr><th>Group</th><th>Families</th><th>Genera</th><th>Species and Subspecies/Varieties</th></tr><tr><th>Native</th><th>Exotic</th><th>Total</th></tr></tbody><tbody><tr><td>Total</td><td>83, 7 (90)</td><td>204, 27 (231)</td><td>449, 102 (551)</td><td>1, 0 (1)</td><td>450, 102 (552)</td></tr></tbody></table>
