Peck ranch collared lizard files
<p>Eastern collared lizards (<em>Crotophytus collaris collaris</em>) were a Missouri state endangered species when this study began in 1982 due to massive local extinction on glades in the Ozarks in central North America. Translocation coupled with glade restoration was initiated in the 1980's, including reintroductions starting in 1984 on Stegall Mountain in southern Missouri. The translocated populations underwent three distinct demographic phases: 1) an isolate phase with no net growth in population size, no colonization of nearby glades, and almost no dispersal among populations, 2) a colonizing phase of high dispersal, colonization of new glades, and population growth that started with the onset of prescribed woodland burning, and 3) a stable metapopulation phase established by 2000 on Stegall Mountain in which the number of occupied glades, total population size, and measures of genetic variation were roughly constant. The data in this dryad submission are association with an in press paper (2022) in <em>Animal Conservation </em>that used these data to infer the age of 1162 marked individuals on the basis of distinct color phases and to assign age-probabilities to 391 marked individuals first captured with adult coloration based on time-of-capture within the field season and snout-vent length, as calibrated from following 529 individuals first captured as hatchlings. Age structure differed significantly between phases. The isolate phase was characterized by an old age structure. The colonization phase had a younger age structure and much more recruitment. The stable metapopulation phase had an intermediate age structure. These dynamic age structure attributes show that species cannot be regarded as static units, and ignoring this dynamism can result in poor conservation practice. These results also validate age-structure as a monitoring device for a conservation program and a tool to identify significant shifts in the environment or management that have a conservation impact, in this case prescribed woodland burning.</p>

Gamma Ray Data: Peck (FIFE)
Airborne soil moisture measurement is based on the difference between natural terrestrial gamma radiation flux measured for comparatively wet and dry soils. The presence of moisture in the soil causes an effective increase in the soil density resulting in an increased attenuation of the gamma flux for relatively wet soil and a correspondingly lower flux at the ground surface. As part of the FIFE experiment, natural terrestrial gamma radiation data over a network of 24 flight lines were collected. The data acquisition procedure was designed to accumulate and store spectral radiation data along a flight line from which estimates of soil moisture could be computed. Ground-based soil moisture measurements were used to make a one-time calibration of the natural terrestrial radioisotope signal over the flight line network. A time-series of airborne soil moisture measurements (to a depth of 20 cm) was compared to an extensive, independent data set of ground-based soil moisture measurements. Estimates for flight line segments were found to have an average RMS error of approximately 2.5 % soil moisture (Peck et al., 1990).
Soil Moisture Data: Peck (FIFE)
Water content measurements by gravimetric methods involve weighing a wet sample, removing the water via drying in an oven, and reweighing the sample to determine the amount of water removed. Water content then is obtained by dividing the difference between wet and dry masses by the mass of the dry sample to obtain the ratio of the mass of water to the mass of dry soil. When multiplied by 100, this becomes the percentage of water in the sample on a dry-mass (or, as often expressed, on a dry-weight) basis. Soil moisture determined using the gravimetric method was measured at 800 sites along 24 transects. These transects were over flown by the airborne Gamma Radiation System used to measure soil moisture. These data are useful for comparison of airborne and ground soil moisture data. This analysis for the airborne Gamma Radiation System, using completely independent soil moisture data showed that the root mean square error of 97 flights was 3.02 percent soil moisture, with a bias of less than 0.5 percent soil moisture (Carroll et al., 1988).
