title: California spotted owl fledgling counts, climate, and landscape habitat at territories on the Lassen National Forest, CA 1991-2010

description: This is a comma separated values (csv) file used to conduct the logistic quantile regression analyses in R provided by Cade et al. (2017. Logistic quantile regression provides improved estimates for bounded avian counts: A case study of California spotted owl fledgling production. The Auk: Ornithological Advances. In press). The data set consists of records of California spotted owl fledgling counts on 88 territories on the Lassen National Forest, CA from 1991-2010. Climatic conditions for various time periods by year for each territory were obtained from PRISM and landscape habitat conditions surrounding owl territories were obtained from LANDFIRE. The owl data were provided by J. J. Keane of the U.S. Forest Service, the climate and habitat data were compiled and meshed with the owl data by B. R. Noon and R. D. Scherer of Colorado State University, and the final data set used for analyses were compiled by B. S. Cade of the U. S. Geological Survey.

title: Modeled Streamflow Metrics on Small, Ungaged Stream Reaches in the Upper Colorado River Basin

description: Modeling streamflow is an important approach for understanding landscape-scale drivers of flow and estimating flows where there are no streamgage records. In this study conducted by the U.S. Geological Survey in cooperation with Colorado State University, the objectives were to model streamflow metrics on small, ungaged streams in the Upper Colorado River Basin and identify streams that are potentially threatened with becoming intermittent under drier climate conditions. The Upper Colorado River Basin is a region that is critical for water resources and also projected to experience large future climate shifts toward a drying climate. A random forest modeling approach was used to model the relationship between streamflow metrics and environmental variables. Flow metrics were then projected to ungaged reaches in the Upper Colorado River Basin using environmental variables for each stream, represented as raster cells, in the basin. Last, the projected random forest models of minimum flow coefficient of variation and specific mean daily flow were used to highlight streams that had greater than 61.84 percent minimum flow coefficient of variation and less than 0.096 specific mean daily flow and suggested that these streams will be most threatened to shift to intermittent flow regimes under drier climate conditions. Map projection products can help scientists, land managers, and policymakers understand current hydrology in the Upper Colorado River Basin and make informed decisions regarding water resources. With knowledge of which streams are likely to undergo significant drying in the future, managers and scientists can plan for stream-dependent ecosystems and human water users. The random forest models we used to project flow metrics to small, ungaged streams varied in model performance between 45.3- and 82.55-percent variance explained. We successfully projected low flow metrics to small, ungaged reaches across the Upper Colorado River Basin using random forest models developed in Reynolds and others (2015) and described in the Methods section of the accompanying Digital Data Series publication. We produced this collection of seven flow metric datasets, one for each modeled flow metric, for small stream reaches across the Upper Colorado River Basin. We produced an eighth dataset for the collection showing modeled intermittency status for each stream reach, including streams that are potentially threatened with intermittency because of drier conditions.'

title: Migrating Bird Survey Data Along the San Pedro River and its Tributaries, Southeastern Arizona, 1989-1994

description: Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minutes after sunrise, lasted for 7 minutes at each point and were completed within 4 hours. Bird detection and species identification were based on visual sighting, song, and call. Recorded observations were the number of individuals of each detected species detected using each detection method at each point and site within specified distance bands during each observation day (each point visited only once per day). Sites were visited from 11 to 22 times across the 3 field seasons. The Arizona bird count data release includes a CSV file with survey and site location data, including latitudes and longitudes for each site location. All codes and acronyms from the data are defined in the metadata, with the exception of a list of 4 letter species acronyms for which there is a key included as an attachment on the ScienceBase page.

title: Geomorphic, climate, streamflow and vegetation data sets to reconstruct channel and vegetation changes associated with the invasion of Russian olive along the Escalante River, Utah 1950-2015.

description: We analyzed historical aerial photography and used dendrochronology to quantify long-term spatial and temporal patterns of narrowing and vegetation expansion, including native cottonwood (Populus fremontii) and non-native Russian olive (Elaeagnus angustifolia), along the largely unregulated Escalante River in Utah, USA. Our general study area was between the town of Escalante and Choprock Canyon, and we focused on two detailed study reaches within this broader area. The study reaches were in long, entrenched meander sections of river: an upper reach, Reach 1, was approximately 15 river kilometers (rkms) long and located between Sand and Boulder creeks within Grand Staircase Escalante National Monument; and a lower reach, Reach 2, was ~16 rkms in length, extending from the Glen Canyon National Recreation Area boundary to just upstream of Choprock Canyon. Russian olive establishment was determined using dendrochronological analysis of cut-stumps in 2015 and analyzed with respect to hydrologic and climatic variables. Geospatial data associated with this work is here made public and includes a total of four shape files and a csv file. One shape file contains point data representing the spatial location and field-determined ages of 729 Russian olive stems. Three shapefiles contain polygons representing active channel, and bottomland geomorphic surfaces along with an estimate of the vegetation cover associated with that surface. These three shape files represent the same study locations in three different eras: 1951/1960, 1981, and 2010. The csv file contains climate and streamflow data that were used in evaluating the relationship between Russian olive establishment and hydroclimate variables. The data released here are associated with a publication that describes the project and results in more detail: Scott, M.L., Reynolds, L.V., Shafroth, P.B., and Spence, J.R. 2018.

title: Demography and habitat use of boreal toads (Anaxyrus boreas) and other amphibians in northern Wyoming (Blackrock).

description: Amphibian decline is a problem of global importance, with over 40% of species considered at risk. This phenomenon is not limited to the tropics or to other countries. Amphibian species in the U.S. are also declining, contributing to the larger, global phenomenon. For example, in the State of Wyoming, the Wyoming toad has been extirpated in the wild and the boreal toad is a species of special concern. Understanding biotic and abiotic factors that influence amphibian persistence is critical for amphibian conservation. This work in northern Wyoming has focused on demography, habitat alteration and creation, and disease in the context of multiple amphibian populations. One of the foci has been to identify the capacity for mitigation wetlands (those created to offset losses due to, for example, road construction) to serve as habitat for amphibians. Four species of amphibians native to Wyoming, including the boreal toad, reside in this region. Our previous research indicates that the toad population at Blackrock is declining at 5-6% per year and that disease due to the amphibian chytrid fungus is contributing to this decline. Our demographic work at this site began in 2003, focusing solely on the boreal toad. Additional funding in 2012 allowed us to increase the scope of the project and assess chorus frog, salamander and Columbia spotted frog populations, invertebrate assemblages, work to quantify the use of mitigation sites by amphibians, and to expand efforts to include sites on Togwotee Pass a short distance away from Blackrock. Because most previous studies of amphibian use of created wetlands have taken place in the eastern United States, this project, incorporating demographic and disease dynamics as well as community composition and mitigation effects of created wetlands, is unique and provides a case study in the Intermountain West. By 2015, all four native amphibian species were observed at one of the created wetlands, and all of them, including the boreal toad, were breeding (evidenced by breeding behavior, eggs or tadpoles).

title: Data on deltamethrin resistance in Oropsylla hirsuta fleas from black-tailed prairie dogs in South Dakota, USA, 2014-2015

description: Data on deltamethrin resistance in Oropsylla hirsuta fleas from black-tailed prairie dogs in Conata Basin, Buffalo Gap National Grassland and Badlands National Park, South Dakota, 2014-2015. Two data files are available, one from &quot;Mortality trials&quot; and another from &quot;recovery trials&quot;. The data from &quot;Mortality trials&quot; includes information on bioassays in which fleas were subjected to deltamethrin in Petri dishes. In 2014, fleas were collected from colonies of black-tailed prairie dogs that had been treated with a deltamethrin-containing dust since 2005 (Dusted) and colonies that had never been treated with deltamethrin (Not Dusted). The fleas were placed in Petri dishes with deltamethrin. All fleas were alive at the start of these trials. The fleas were assessed for mortality every 5 minutes until all fleas appeared dead (i.e., for 55 minutes). The data includes the treatment category for each line of data (fleas from Dusted or Not Dusted colonies); the minute marks for assays (0 through 55 minutes); and the numbers of fleas alive during each minute mark. The data from &quot;Recovery trials&quot; includes information on bioassays in which fleas were assessed for recovery after deltamethrin treatment. After the mortality trials (described above), all fleas appeared dead. Fleas were then placed in clean vials or Petri dishes and assessed for recovery 40 hours later (i.e., assessed for an ability to actually survive and recover from deltamethrin treatment). The data (2014 and 2015 separately) includes the years of sampling; the treatment category for each line of data (fleas from Dusted or Not Dusted colonies); the numbers of fleas that recovered (i.e., were resistant to deltamethrin); and the numbers of fleas that were actually dead. Individual study sites are occupied by species of conservation concern, including endangered black-footed ferrets. Thus, the data are linked to the general study area, Conata Basin, South Dakota. Funding and logistical support were provided by US Geological Survey, US Forest Service, National Park Service, US Fish and Wildlife Service, Colorado State University, the Centers for Disease Control and Prevention, Prairie Wildlife Research, National Fish and Wildlife Foundation, and World Wildlife Fund. This research was supported by Grant-Cooperative Agreement Number G14AC00403 from the US Geological Survey.

title: Grooming behaviors of black-tailed prairie dogs in Phillips County, Montana, 2006

description: Data on factors that affect the grooming behaviors of black-tailed prairie dogs in Phillips County, Montana, 2006. Each line of data presents information for a focal observation of a single black-tailed prairie dog. The data includes information on the date of each observation, the approximate coordinates of sites, the time of each observation, indexed wind speed, indexed temperature, the presence or absence of deltamethrin dust (pulicide) treatment, the amount of time a human spent observing the prairie dog, the proportion of time spent scratching by the prairie dog, the proportion of time spent oral autogrooming by the prairie dog, the proportion of time spent allogrooming by the prairie dog, and the overall proportion of time spent grooming by the prairie dog (scratching, oral autogrooming, and allogrooming combined). The coordinates of sites are linked to colonies of prairie dogs, not locations for individual prairie dogs. The spatial location for each prairie dog within a colony is the centroid point for that colony. Financial support was provided by the Denver Zoological Foundation, the U. S. Geological Survey, the U. S. Fish and Wildlife Service, the Bureau of Land Management and Indiana University-Purdue University Indianapolis.

title: Sex, length, total mass, fat mass, and specimen condition data for 248 Burmese pythons (Python bivittatus) collected in the Florida Everglades

description: These data were collected from Burmese pythons removed from the Florida everglades as part of invasive-species management. After euthanasia, we sexed (male or female) and measured the snout-vent length (SVL; cm) and total body mass (g) for each python. We also measured total fat mass (g) by removing all visible fat bodies from the coelomic cavity and weighing this mass. For a subset of specimens, we recorded whether the pythons were put on ice after euthanasia and measured within 24 hours ('fresh') or whether the pythons were frozen after euthanasia, thawed, and then measured ('frozen'). These data were used to validate several body condition indices in Burmese pythons.

title: Woody riparian invasive plant presence, stem density, and rank dominance and environmental conditions in 2012 at 238 bridge crossings in the Colorado Headwaters, upper/middle Rio Grande, upper Arkansas, and South Platte River Basins, USA

description: This dataset presents observations and measurements of riparian plant invasion, community composition, and environmental conditions at 238 bridge crossings in four western USA river basins: the Colorado Headwaters, upper/middle Rio Grande, upper Arkansas River, and South Platte River (281,946 square kilometers). The 238 sites are a stratified random sample of all bridge crossings in the river basins, with roughly equal numbers of sites in landscapes dominated by (1) urban and residential (developed) land-use, (2) agricultural (cultivated) land-use, and (3) undeveloped land cover. The dataset includes field observations of stem counts for three non-native riparian woody plant taxa (Tamarix ramosissima x T. chinensis hybrids - tamarisk or saltcedar, Elaeagnus angustifolia - Russian olive, Ulmus pumila - Siberian elm) in each of four size classes for each taxon, to evaluate presence, stem density, and size class distributions of these taxa. Second, it includes field observations ranking the five woody taxa with the highest cover in the riparian floodplain, to evaluate overall riparian plant community composition as well as rank dominance of the three non-native taxa. Third, the dataset includes various measures of environmental conditions at the sites, including adjacent human land-use, nearby human planting of the three non-native taxa, mean annual temperature and precipitation, watershed drainage area, streamflow intermittency, upstream reservoir storage, streambank stabilization, floodplain domestic grazing, and riparian forest cover. Some environmental conditions were measured in the field, some were measured in aerial photographs, and some measurements were obtained from previously existing data layers. Fourth, the dataset includes presence/absence data for the three non-native taxa across a wider area of the floodplain at a subset of the sites that had been sampled previously in 1997-2001 for a separate dataset (n=33 including two that were not included in the 238 sites described above).
