Matthew Neilson, Ph.D.
My interests lie in the ecology, biology, systematics, population genetics, and zoogeography of fishes. I currently work with the USGS Nonindigenous Aquatic Species Database program helping to refine our understanding of nonnative fish distributions and impacts in the United States.

Implementing FAIR practices: Storing and displaying eDNA data in the USGS Nonindigenous Aquatic Species database
We are working to incorporate environmental DNA (eDNA) data into the Nonindigenous Aquatic Species (NAS) database, which houses over 570,000 records of nonindigenous species nationally, and already is used by a broad user-base of managers and researchers regularly for invasive species monitoring. eDNA studies have allowed for the identification and biosurveillance of numerous invasive and...
Establishing standards and integrating environmental DNA (eDNA) data into the USGS Nonindigenous Aquatic Species database
Environmental DNA (eDNA) testing allows for high sensitivity monitoring efforts of cryptic species in large, remote systems and is performed by investigating water and soil samples for sloughed DNA. Having access to eDNA datasets across multiple taxa and ecosystems is necessary for improved coordination among researchers and management. Additionally, quality control protocols are needed to vet...
National Public Screening Tool for Invasive and Non-native Aquatic Species Data
Identifying the leading edge of a biological invasion can be difficult. Many management and research entities have biological samples or surveys that may unknowingly contain data on nonindigenous species. The new Nonindigenous Aquatic Species (NAS) Database automated online tool “SEINeD” (Screen and Evaluate Invasive and Non-native Data) will allow a user to search for these nonindigenous...
The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)
The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.
Defining Native Ranges of U.S. Inland Fishes
Understanding the native versus non-native range of a species can provide useful information about dispersal, population distribution patterns, and human mediated movement across hydrologic barriers. The USGS Nonindigenous Aquatic Species (NAS) Program is working with partners to define native ranges of inland fishes in the United States to help identify which species should be included in the...
The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
Knowledge Extraction Algorithms (KEA): Turning Literature Into Data
Identifying, extracting, and mobilizing information from current and historical literature is a time-consuming part of organizing and collating synthetic data productions. This project explored the use of algorithm-based methods to identify and extract occurrence information from the GeoDeepDive (GDD) literature database to support upkeep of the Nonindigenous Aquatic Species (NAS) data. The...
National Alert Risk Mapper for Nonindigenous Aquatic Species
The Nonindigenous Aquatic Species (NAS) Database and Alert System (https://nas.er.usgs.gov/default.aspx) provides a framework for the rapid dissemination of new invasions as they are incorporated into the NAS Database. The system notifies registered users of new sightings of >1,330 non-native aquatic species as part of national-scale early...
Great Lakes Aquatic Nuisance Species Information System
The Great Lakes Aquatic Nuisance Species Information System (GLANSIS) was developed by the NOAA Great Lakes Science Center to monitor nonindigenous aquatic species introductions into the Great Lakes region.
Nonindigenous Aquatic Species (NAS) Program
Welcome to the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general...
Nonindigenous Aquatic Species Database and Website (NAS)
Nonindigenous - non-native - species threaten biodiversity, but the distribution of these species is not well-known. The Nonindigenous Aquatic Species (NAS) database tracks occurrence data on non-native aquatic plant and animal species throughout the United States, and provides the public with species profiles, distribution maps, and online/real-time queries for state/hydrologic basin-...
NASWeb API Web Services Access to the Nonindigenous Aquatic Species Database
The national Nonindigenous Aquatic Species (NAS) Database Program serves as a repository for geo-referenced occurrence data on introduced aquatic organisms across the nation. The NAS Program, including the database and website (http://nas.er.usgs.gov), is a well-known resource and has been widely referenced in peer reviewed literature, agency reports, state...
Community for data integration 2018 funded project report
The U.S. Geological Survey Community for Data Integration annually funds small projects focusing on data integration for interdisciplinary research, innovative data management, and demonstration of new technologies. This report provides a summary of the 10 projects funded in fiscal year 2018, outlining their goals, activities, and accomplishments.

The Australian redclaw crayfish, Cherax quadricarinatus, is a popular aquaculture crayfish that has been introduced around the world. Here we report the first occurrence of the species in the United States in Lake Balboa, Los Angeles, California. The impacts of this species are largely unknown, and further research is needed to determine the...
Morningstar, Cayla; Daniel, Wesley; Neilson, Matthew; Yazaryan, Ara K.Interactive mapping of nonindigenous species in the Laurentian Great Lakes
Nonindigenous species pose significant risks to the health and integrity of ecosystems around the world. Tracking and communicating the spread of these species has been of interest to ecologists and environmental managers for many years, particularly in the bi-national Laurentian Great Lakes of North America. In this paper, we introduce the Great...

Understanding the spatial and temporal dynamics underlying the introduction and spread of nonindigenous aquatic species (NAS) can provide important insights into the historical drivers of biological invasions and aid in forecasting future patterns of nonindigenous species arrival and spread. Increasingly, public databases of species observation...

Non-native fish introductions are a major threat to biodiversity and fisheries, and occur through numerous pathways that vary regionally in importance. A key strategy for managing invasions is to focus prevention efforts on pathways posing the greatest risk of future introductions. We identified high-risk pathways for fish establishment in the Mid...
