Bullseye snakehead, Channa marulius, was first detected in 2000 in the southern Florida town of Tamarac and has been expanding its geographic range. Environmental DNA (eDNA) analysis is a newly-developed technique used to non-invasively detect cryptic or low-density species, or those that are logistically difficult to study. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of target species eDNA. To help delineate bullseye snakehead’s geographic range, we developed and validated a species-specific eDNA assay for both quantitative and droplet digital PCR (ddPCR). We then used ddPCR to assess 16 locations in southeast Florida...
We analyzed the single nucleotide polymorphisms (SNPs) present in the genomes of moose representing 3 subspecies in the contiguous United States. Blood samples were collected opportunistically from collaborators during field efforts or were supplied to our lab from collaborators' archives, and represented moose sampling occurring between 2009-2017. DNA was extracted, sequenced using next generation sequencing, and SNPs analyzed using the genetics programs Structure and Tess3, and by performing basic population statistics. These analyses were used to determine the population structure of moose at the subspecies level.
These data represent the standard curve values as well as measurements of cytokine and reference gene transcripts from blood samples collected from Florida manatees and quantified using quantitative PCR.

Invasive alien species (IAS) are a rising threat to biodiversity, national security, and regional economies, with impacts in the hundreds of billions of U.S. dollars annually. Proactive or predictive approaches guided by scientific knowledge are essential to keeping pace with growing impacts of invasions under climate change. Although the rapid development of diverse technologies and approaches has produced tools with the potential to greatly accelerate invasion research and management, innovation has far outpaced implementation and coordination. Technological and methodological syntheses are urgently needed to close the growing implementation gap and facilitate interdisciplinary collaboration and synergy among...

Abstract (from Conservation Genetics): Genome-wide evaluations of genetic diversity and population structure are important for informing management and conservation of trailing-edge populations. North American moose (Alces alces) are declining along portions of the southern edge of their range due to disease, species interactions, and marginal habitat, all of which may be exacerbated by climate change. We employed a genotyping by sequencing (GBS) approach in an effort to collect baseline information on the genetic variation of moose inhabiting the species’ southern range periphery in the contiguous United States. We identified 1920 single nucleotide polymorphisms (SNPs) from 155 moose representing three subspecies...

Objective We use Tempus blood RNA tubes (Applied Biosystems) during health assessments of American moose (Alces alces spp.) as a minimally invasive means to obtain RNA. Here we describe a novel protocol to additionally isolate high-quality DNA from the supernatant remaining after the RNA isolation methodology. Metrics used to qualify DNA quality included measuring the concentration, obtaining a DNA integrity number from a genomic DNA ScreenTape assay (Agilent), and running the isolated DNA on an agarose gel. Results Of the 23 samples analyzed, the average DNA concentration was 121 ng/µl (range 4–337 ng/µl) and a genomic DNA ScreenTape assay of seven samples indicated high DNA integrity values for 6 of the 7 samples...

Data represent the metrics measured to validate the novel technique for isolating DNA from the supernatant of an RNA isolation protocol using blood collected into Tempus blood RNA tubes.
Reported here are the fluorescence data points recorded from CRISPR/Cas12a biosensor assays to detect the presence or absence of DNA from Pseudogymnoascus destructans (Pd), the causative fungal agent of white-nose syndrome in bats, from artificial controls, dermal swab, and guano samples. Ct values from qPCR experiments are also provided in a table. Furthermore, we also provide the GenBank accession numbers used to develop the aforementioned CRISPR/Cas12a biosensor assay for Pd DNA detection.
Environmental DNA (eDNA) detection is a rapidly expanding technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of targeted eDNA. To help delineate manatee habitat ranges, high use areas, and seasonal population changes, a cytochrome-b quantitative PCR and state-of-the-art droplet digital PCR (ddPCR) eDNA assay was developed for the three extant and vulnerable manatee species: both subspecies of the West Indian manatee (Florida and Antillean), the African manatee and Amazonian manatee. Occurrence...
Data files for manuscript "Improving eDNA yield and inhibitor reduction through increased water volumes and modified multi-filter isolation techniques". These include the results of different treatments for inhibitor removal from a water sample and DNA yield quantities from such tests. Environmental DNA (eDNA) methods detect genetic material that is shed into the environment through skin cells and excrement by plants and animals. These methods are increasingly being applied to detect imperiled and invasive species for range assessment and occurrence estimates. To improve the recovery and detection of eDNA, we tested and optimized three basic protocols to 1) assess whether eDNA concentration increase in a linear...

Environmental DNA (eDNA) detection of invasive species can be used to delimit occupied ranges and estimate probabilities to inform management decisions. Environmental DNA is shed into the environment through skin cells and bodily fluids and can be detected in water samples collected from lakes, rivers, and swamps. In south Florida, invasive Burmese pythons occupy much of the Greater Everglades in mostly inaccessible habitat and are credited with causing severe declines of native species’ populations. Detection of Burmese pythons by traditional methods, such as trapping and visual searching, have been largely ineffective, making eDNA a superior method for differentiating invaded habitat. We adapted a quantitative...
