Pairwise FST values for Aedes aegypti populations in Florida and southern California
<p>In the affiliated paper we compare likely the oldest populations of <i>Aedes aegypti</i> in continental North America with some of the newest to illuminate the range of genetic diversity and structure that can be found within the invasive range of this important disease vector. <i>Aedes aegypti</i> populations in Florida have likely persisted since the 1600-1700s, while populations in southern California derive from new invasions that occurred in the last ten years. For this comparison, we genotyped 1,193 individuals from 29 sites at 12 highly variable microsatellites and a subset of these individuals at 23,961 single nucleotide polymorphisms (SNPs). This dataset contains the pairwise FST values generated with both genetic datasets.</p>

Data from: Tall, heterogenous forests improve prey capture, delivery to nestlings, and reproductive success for Spotted Owls in southern California
<p>Predator-prey interactions can be profoundly influenced by vegetation conditions, particularly when predator and prey prefer different habitats. Although such interactions have proven challenging to study for small and cryptic predators, recent methodological advances substantially improve opportunities for understanding how vegetation influences prey acquisition and strengthen conservation planning for this group. The California Spotted Owl (<em>Strix</em> <em>occidentalis</em> <em>occidentalis</em>) is well-known as an old-forest species of conservation concern, but whose primary prey in many regions – woodrats (<em>Neotoma</em> spp.) – occurs in a broad range of vegetation conditions. Here, we used high-resolution GPS tracking coupled with nest video monitoring to test the hypothesis that prey capture rates vary as a function of vegetation structure and heterogeneity, with emergent, reproductive consequences for Spotted Owls in Southern California. Foraging owls were more successful capturing prey, including woodrats, in taller multilayered forests, in areas with higher heterogeneity in vegetation types, and near forest-chaparral edges. Consistent with these findings, Spotted Owls delivered prey items more frequently to nests in territories with greater heterogeneity in vegetation types and delivered prey biomass at a higher rate in territories with more forest-chaparral edge. Spotted Owls had higher reproductive success in territories with higher mean canopy cover, taller trees, and more shrubby vegetation. Collectively, our results provide additional and compelling evidence that a mosaic of large tree forests with complex canopy and shrubby vegetation increases access to prey with potential reproductive benefits to Spotted Owls in landscapes where woodrats are a primary prey item. We suggest that forest management activities that enhance forest structure and vegetation heterogeneity could help curb declining Spotted Owl populations while promoting resilient ecosystems in some regions.</p>
ADCP data collected in the Southern California Bight by SWIFT drifters as part of the ONR "Langmuir Circulation Departmental Research Initiative (LC-DRI)"
<p>This is the public archive for ADCP data collected with SWIFT drifters during the 'Langmuir Circulation' Office of Naval Research Departmental Research Initiative (LC-DRI) field experiment, conducted between March 19th and April 6th, 2017 in the Southern California Bight 40 km west of Catalina Island. SWIFTs were deployed and recovered from the R/V R.G. Sproul during cruise SP1709 (Cruise DOI: 10.7284/907464). SWIFTs were deployed during storms with wind speeds up to 20 m/s and sampled strong diurnal warm layers during weaker wind periods.</p>
Southern California mule deer survey dataset
<p>In March 2019, October 2019, and February 2020 the California Department of Fish and Wildlife conducted total count aerial surveys (Schlossberg et al., 2016) in the three study areas using a contracted four seat Bell 407 helicopter (Air Shasta Rotor & Wing, Redding, CA). These surveys were designed to cover the entire study area at three study sites in San Diego County: San Felipe Valley Wildlife Area and San Felipe Hills (SFVH), Kitchen Creek (KC), and Rancho Jamul Ecological Reserve and Hollenbeck Canyon Wildlife Area (RJHB). Surveyors flew parallel transects spaced approximately 300 m apart, with transects over mountainous terrain oriented along contour lines. All surveys occurred between 0700 and 1700 hours each day. To reduce the possibility of double counts of deer groups, where observers record the same marked deer more than once, each survey site was split into polygons that were each completed with one load of fuel if possible, with adjacent polygons completed consecutively, and each survey site covered in two days or less. During survey flights, observers simultaneously recorded data for the double observer (DO) and sightability methods. </p>
