Environmental DNA (eDNA) refers to the genetic material that can be extracted from bulk environmental samples such as soil, water, and even air. The rapidly expanding study of eDNA has generated unprecedented ability detect species conduct analyses for conservation, management, research, particularly in scenarios where collection whole organisms is impractical or impossible. While number studies demonstrating successful detection increased recent years, less research explored "ecology"...
Summary Species detection using environmental DNA ( eDNA ) has tremendous potential for contributing to the understanding of ecology and conservation aquatic species. Detecting species methods, rather than directly sampling organisms, can reduce impacts on sensitive increase power field surveys rare elusive The sensitivity however, requires a heightened awareness attention quality assurance control protocols. Additionally, interpretation data demands careful consideration multiple factors....
Genetic identification of aqueous environmental DNA (eDNA) provides site occupancy inferences for rare aquatic macrofauna that are often easier to obtain than direct observations organisms. This relative ease makes eDNA sampling a valuable tool conservation biology. Research on the origin, state, transport, and fate shed by is needed describe spatiotemporal context eDNA-based guide design. We tested hypothesis more concentrated in surficial sediments surface water measuring concentration...
Summary Using environmental DNA ( eDNA ) to detect aquatic macroorganisms is a new survey method with broad applicability. However, the origin, state and fate of aqueous macrobial – which collectively determine how well can serve as proxy for directly observing organisms should be captured, purified assayed are poorly understood. The size particles provides clues about their fate. We used sequential filtration fractionation measure particle distribution (PSD) , specifically Common Carp...
Freshwater fauna are particularly sensitive to environmental change and disturbance. Management agencies frequently use fish amphibian biodiversity as indicators of ecosystem health a way prioritize assess management strategies. Traditional aquatic bioassessment that relies on capture organisms via nets, traps electrofishing gear typically has low detection probabilities for rare species can injure individuals protected species. Our objective was determine whether DNA (eDNA) sampling...
Impacts of nonindigenous crayfishes on ecosystem services exemplify the mixture positive and negative effects intentionally introduced species. Global introductions for aquaculture ornamental purposes have begun to homogenize naturally disjunct global distributions crayfish families. Negative impacts include loss provisioning (e.g., reductions in edible native species, reproductive interference or hybridization with crayfishes), regulatory lethal disease spread, increased costs agriculture...
Species richness is a metric of biodiversity that represents the number species present in community. Traditional fisheries assessments rely on capture organisms often underestimate true richness. Environmental DNA (eDNA) metabarcoding an alternative tool infers by collecting and sequencing ecosystem. Our objective was to determine how spatial distribution samples “bioinformatic stringency” affected eDNA-metabarcoding estimates compared with capture-based 2.2 ha reservoir. When bioinformatic...
Abstract The foundation for any ecological study and the effective management of biodiversity in natural systems requires knowing what species are present an ecosystem. We assessed fish communities a stream using two methods, depletion‐based electrofishing environmental DNA metabarcoding ( eDNA ) from water samples, to test hypothesis that provides alternative means determining richness identities In northern Indiana stream, yielded direct estimate 12 mean estimated (Chao II estimator) 16.6...
Indirect, non-invasive detection of rare aquatic macrofauna using aqueous environmental DNA (eDNA) is a relatively new approach to population and biodiversity monitoring. As such, the sensitivity monitoring results different methods eDNA capture, extraction, being investigated in many ecosystems species. One first largest conservation programs with eDNA-based as central instrument focuses on Asian bigheaded carp (Hypophthalmichthys spp.), an invasive fish spreading toward Laurentian Great...
Abstract Knowledge about the size of environmental DNA (eDNA) and eDNA‐bearing particles in aquatic environments is integral to efficient sensitive analyses. To explore influence factors on eDNA particle distribution (PSD), we manipulated fish communities across nine experimental ponds, which led differences a suite covariates (biochemical oxygen demand, chlorophyll concentration, conductivity, dissolved oxygen, pH, temperature, turbidity) over 5 months. At end experiment, serially filtered...
SUMMARY Electrocommunication signals in electric fish are diverse, easily recorded and have well-characterized neural control. Two signal features, the frequency waveform of organ discharge (EOD), vary widely across species. Modulations EOD (i.e. chirps gradual rises) also function as active communication during social interactions, but they been studied relatively few We compared electrocommunication 13 species largest gymnotiform family,Apteronotidae. Playback stimuli were used to elicit...

The size particles provides clues about their fate. We used sequential filtration fractionation to measure, first time, particle distribution (PSD) eDNA, specifically...
Noninvasive genetic sampling enables biomonitoring without the need to directly observe or disturb target organisms. This paper describes a novel and promising source of noninvasive spider insect DNA from webs. Using black widow spiders (Latrodectus spp.) fed with house crickets (Acheta domesticus), we successfully extracted, amplified, sequenced mitochondrial web samples that identified both prey species. Detectability did not differ between assays amplicon sizes 135 497 base pairs. Spider...
The lizard genus Liolaemus is endemic to temperate South America and includes approximately 200 species. koslowskyi occurs in north‐western Argentina, where it confined a system of interior basins valleys. This topographically complex region now viewed as different enough that has been suggested for recognition separate zoogeographical region: Monte Desert Mountains Isolated Valleys. Here we use the mtDNA cytochrome b sequence data investigate phylogeographical pattern L. its relationships...
The genetic differentiation of populations within the E. risdonii Hook.f.-E.tenuiramis Miq.complex and affinities isolated peppermint from Tasmania's south-west World Heritage Area (WHA) were assessed in a morphometric study glasshouse-grown seedlings.Four well-differentiated phenetic groups risdonii-E.tenuiramis complex identified : (1) risdonii, (2) Southern tenuiramis, (3) Northern tenuiramis (4) Peninsula tenuiramis.The between as is much smaller than separation extreme forms (Northern...
Noninvasive genetic approaches enable biomonitoring without the need to directly observe or disturb target organisms. Environmental DNA (eDNA) methods have recently extended this approach by assaying material within bulk environmental samples a priori knowledge about presence of biological material. This paper describes novel and promising source noninvasive spider insect eDNA from webs. Using black widow spiders (Latrodectus spp.) fed with house crickets (Acheta domesticus), we successfully...
A transition between polymorphic phenotypes was observed within a single male Sternarchogiton nattereri. This individual initially toothless, but developed into toothed phenotype characterized by swollen distal upper jaw and distinctive external dentition. Changes in morphological features were accompanied shifts electrocommunication (chirping) behaviour.

Abstract Over 60% of the Alabama population is medically underserved, including entire many counties. These counties are generally rural and have transportation barriers, thus a lack access to healthcare results in poor cancer outcomes. gaps, addition lower education levels mistrust towards researcher/healthcare providers, highlight challenges but also need make difference this underserved understudied population. In general, recruitment for human genetic research studies presents major...
