In this observational pilot study, we worked at the largest existing solar tower facility in the world (Ivanpah Solar Electric Generating System - ISEGS) to assess the efficacy of using radar, surveillance video, and insect trapping to monitor animals flying near the towers. During week-long site visits in May and September, we monitored the airspace surrounding towers and observed insects, occasional birds, and bats under a variety of environmental and operational conditions. This dataset enumerates invertebrates captured using both malaise and funnel traps placed on the ground in the immediate vicinity of solar towers in the locations shown in Figure 2 of the associated paper. The locational information below...

In this observational pilot study, we worked at the largest existing solar tower facility in the world (Ivanpah Solar Electric Generating System - ISEGS) to assess the efficacy of using radar, surveillance video, and insect trapping to monitor animals flying near the towers. During week-long site visits in May and September, we monitored the airspace surrounding towers and observed insects, occasional birds, and bats under a variety of environmental and operational conditions. This dataset consists of raster portable network graphics (png) images of the planned position indicator (ppi) display from a Furuno FR2127 portable radar unit to a maximum range of 1.5 km. A new image is written with each rotation of the...
The data are .csv files of tagged sea otter re-sighting locations (henceforth, resights) collected in the field using a combination of VHF radio telemetry and direct observation using high powered (80x) telescopes. Sea otters were tracked by shore based observers from the date of tagging until the time of radio battery failure or the animal’s death, whichever comes first. The frequency of re-sighting was opportunistic, depending on logistical factors such as coastal access, but generally ranged from daily to weekly. Location coordinates are reported as X and Y coordinates in the projection/datum California Teale-Albers NAD 1927. Each file contains resight data for one individual sea otter collected over a period...

In this observational pilot study, we worked at the largest existing solar tower facility in the world (Ivanpah Solar Electric Generating System - ISEGS) to assess the efficacy of using radar, surveillance video, and insect trapping to monitor animals flying near the towers. During week-long site visits in May and September, we monitored the airspace surrounding towers and observed insects, occasional birds, and bats under a variety of environmental and operational conditions. This dataset is comprised of the unedited digital video imagery we gathered during those site visits. There are four types of video imagery included in the data set: (1) "EMCCD camera" is the output of an electron multiplying charge-coupled-device...
Step selection functions use animal movement patterns to estimate habitats available at each step along a movement track. These data were generated from four species of waterfowl (Anser albifrons [greater white-fronted goose], Anser caerulescens caerulescens [lesser snow goose], Anas platyrhynchos [mallard], Anas acuta [northern pintail]) using the Central Valley of California 2016 to 2022 that were fit with tracking devices collecting GPS data every hour (or subset to hourly locations). Observed movements were used to estimate a 2-mixture log-normal step length distribution for each species. The shorter mean step length mixture generally reflected step lengths consistent with individual immobility and GPS errors....

A huge road network with vehicles ramifies across the land, representing a surprising frontier of ecology. Species-rich roadsides are conduits for few species. Roadkills are a premier mortality source, yet except for local spots, rates rarely limit population size. Road avoidance, especially due to traffic noise, has a greater ecological impact. The still-more-important barrier effect subdivides populations, with demographic and probably genetic consequences. Road networks crossing landscapes cause local hydrologic and erosion effects, whereas stream networks and distant valleys receive major peak-flow and sediment impacts. Chemical effects mainly occur near roads. Road networks interrupt horizontal ecological flows,...

During week-long site visits in May and September, we monitored the airspace surrounding towers and observed insects, occasional birds, and bats under a variety of environmental and operational conditions. This dataset is comprised of the unedited digital thermal samples we gathered during those site visits and consist of 1280x720 pixel arrayed infrared measures from a FLIR SC8340HD science-grade thermal (SGT) camera with a 200mm lens. The data...
Capture, GPS-collar tagging, and release of cougars was conducted in northern Arizona and southern Utah and Nevada, USA, from 2003 to 2013 by the U.S. Geological Survey and the National Park Service (Northern Arizona University IACUC Protocol # 02-082-R4), resulting in GPS-tracking and monitoring of study animal activities. This data set includes six individuals that met three criteria: 1) few missing data (≥ 85% fix success rate), 2) long periods of continuous monitoring, with a minimum of 1000 observations, and 3) established home range with no evidence of dispersal. It includes four females (C04, AS02, P26, and C07) and two males (Z04 and AS07), ranging in age from 1.5 – 4 years in age. Two females (C04 and AS02)...
These data consist of several discrete data resources captured at the Ivanpah Solar Electric Generating System (ISEGS) during 2014. The data include 1) Thermal (infrared) data recordings 2) Tabular data representing insect (invertebrate) measurements 3) Radar data 4) Video files These data support the following publication: Diehl, R. H, E. W. Valdez, T. M. Preston, M. J. Wellik, and P. M. Cryan. 2016. Evaluating the effectiveness of wildlife detection and observation technologies at a solar power tower facility. PLOS ONE.
The green wave hypothesis (GWH) states that migrating animals should track or ‘surf’ high-quality forage at the leading edge of spring green-up. To index such high-quality forage, recent work proposed the instantaneous rate of green-up (IRG), i.e. rate of change in the normalized difference vegetation index over time. Despite this important advancement, no study has tested the assumption that herbivores select habitat patches at peak IRG. We evaluated this assumption using step selection functions parametrized with movement data during the green-up period from two populations each of bighorn sheep, mule deer, elk, moose and bison, totalling 463 individuals monitored 1–3 years from 2004 to 2014. Accounting for variables...

521 unique elk were monitored across several years with GPS collars in the Greater Yellowstone Ecosystem to determine winter-to-winter annual dispersal distances. There were a total of 704 annual movements. The dataset spans from 2001 to 2015. Annual movements were based on a single location in January or February and another location in the subsequent winter. An individual elk was included at most three times (once for each year) in the data. All elk were female, except one of the individuals in the dataset was a male. We included his movement in the analysis for completeness, but as there was only one male we chose not to directly model any differences in movement behavior between male and female elk.
