“…This may have helped to ensure the detection of species with diverse habitat preferences. Some studies have found that eDNA is often well mixed throughout a system (Zhang et al 2020), but others found that DNA can clump together (Furlan et al 2016; Williams, Huyvaert, Vercauteren, Davis, Piaggio, 2018); therefore, the optimal sampling strategy should consider both spatial distribution which could be important for stagnant systems where there is low mixing or large waterbodies and total volume which could be important to mitigate effects of DNA clumping. Conventional sampling approaches often have biased sampling efficiency for different species (Murphy & Willis, 1996); therefore, multiple types of sampling are necessary to fully describe local fish communities (Clark et al., 2007).…”

“…diaphanus in Lake Wingra, it is possible that F . diaphanus recently recolonized the lake and is a true detection (Willink et al, 2018). Unfortunately, it is very difficult conclusively say whether detections are false‐positives due to contamination, misassignment, or from DNA that originated from adjacent unsampled streams or wetlands or transferred to the lake by some other means.…”

“…Given the extensive conventional sampling of both lakes, it is unlikely that the detections are from DNA shed from individuals residing in each waterbody. In certain cases, such as the detection of F. diaphanus in Lake Wingra, it is possible that F. diaphanus recently recolonized the lake and is a true detection (Willink et al, 2018). Unfortunately, it is from any of these species were in our samples, it is likely they assigned to a closely related species or assigned to a higher taxonomic level (e.g.…”

Aim To evaluate the ability of precipitation‐based environmental DNA (eDNA) sample collection and mitochondrial 12S metabarcoding sequencing to reconstruct well‐studied fish communities in lakes and rivers. Specific objectives were to 1) determine correlations between eDNA species detections and known community composition based on conventional field sampling, 2) compare efficiency of eDNA to detect fish biodiversity among systems with variable morphologies and trophic states, and 3) determine if species habitat preferences predict eDNA detection. Location Upper Great Lakes Region, North America. Methods Fish community composition was estimated for seven lakes and two Mississippi River navigation pools using sequence data from the mitochondrial 12S gene amplified from 10 to 50 water samples per waterbody collected in 50‐mL centrifuge tubes at a single time point. Environmental DNA (eDNA) was concentrated without filtration by centrifuging samples to reduce per‐sample handling time. Taxonomic detections from eDNA were compared to established community monitoring databases containing up to 40 years of sampling and a detailed habitat/substrate preference matrix to identify patterns of bias. Results Mitochondrial 12S gene metabarcoding detected 15%–47% of the known species at each waterbody and 30%–76% of known genera. Non‐metric multidimensional scaling (NMDS) assessment of the community structure indicated that eDNA‐detected communities grouped in a similar pattern as known communities. Discriminant analysis of principal components indicated that there was a high degree of overlap in habitat/substrate preference of eDNA‐detected and eDNA‐undetected species suggesting limited habitat bias for eDNA sampling. Main conclusions Large numbers of small volume samples sequenced at the mitochondrial 12S gene can describe the coarse community structure of freshwater systems. However, additional conventional sampling and environmental DNA sampling may be necessary for a complete diversity census.

“…Initially native to the Atlantic Coast and inland towards Lake Erie (Figure 1), invasive Eastern Banded Killifish have rapidly spread throughout the historical range of Western Banded Killifish over the last several decades, particularly in Lake Michigan and connected waters (Hartman et al., 2023; Willink et al., 2018). The invasion of Eastern Banded Killifish poses a threat to already imperilled Western Banded Killifish, which declined due to habitat transformation or loss throughout the 20th century in Illinois, United States (US; Smith, 1979) and Wisconsin, United States (Lyons, 1989).…”

“…For this study, we used the confluence of the Chicago River and Lake Michigan in Illinois (41.88, −87.61) as the proposed source of the invasion for analyses focused on the spread of Eastern Banded Killifish as related to patterns of admixture and introgression. Admixed individuals between Eastern and Western Banded Killifish have previously been documented based on both mitochondrial and nuclear sequences as well as morphological analyses (April & Turgeon, 2006;Willink et al, 2018), but our study is the first to apply next-generation RADseq approaches to investigate the population genomics of these fish.…”

Hybridisation can be an important driver of evolutionary change, but hybridisation with invasive species can have adverse effects on native biodiversity. While hybridisation has been documented across taxa, there is limited understanding of ecological factors promoting patterns of hybridisation and the spatial distribution of hybrid individuals. We combined the results of ecological niche modelling (ENM) and restriction site‐associated DNA sequencing to test theories of niche conservatism and biotic resistance on the success of invasion, admixture, and extent of introgression between native and non‐native fishes. We related Maxent predictions of habitat suitability based on the native ranges of invasive Eastern Banded Killifish (Fundulus diaphanus diaphanus Lesueur 1817) and native Western Banded Killifish (Fundulus diaphanus menona Jordan and Copeland 1877) to admixture indices of individual Banded Killifish. We found that Eastern Banded Killifish predominated at sites predicted as suitable from their ENM, consistent with niche conservatism. Admixed individuals were more common as Eastern Banded Killifish habitat suitability declined. We also found that Eastern Banded Killifish were most common at sites closest to the presumed source of this invasion, whereas the proportion of admixed individuals increased with distance from the source of invasion. Lastly, we found little evidence that habitat suitability for Western Banded Killifish provides biotic resistance from either displacement by, or admixture with, invasive Eastern Banded Killifish. Our study demonstrates that ENMs can inform conservation‐relevant outcomes between native and invasive taxa while emphasising the importance of protecting isolated Western Banded Killifish populations from invasive conspecifics.

Nonnative fishes can cause ecological impacts as invasive species, but identifying which nonnative species have harmful impacts is critical to prioritizing management and policy responses. Here, we characterized the state of knowledge on the impacts of a possibly overlooked group of invasive species in the United States: non-game native transplant (NGNT) fishes. We propose that NGNT fishes may be understudied relative to nonnative game fish and exotic species introduced from outside of the country.Only 14% of 220 freshwater NGNT fishes in the United States have been studied for possible negative impacts. We found that researchers have neglected to study impacts of many widespread NGNT species, and some regions with high NGNT species richness have had no studies of the impacts of any NGNT species. Genetic and ecosystem impacts of NGNT fishes have been particularly neglected relative to population and community impacts. We recommend that researchers and funding entities direct their attention to prospective impacts of the most widespread NGNT species in the least studied U.S. river basins to identify which of these fishes require prevention and management as invasive species.
