Data supporting Landsat time series assessment of invasive annual grasses following energy development
To determine if invasive annual grasses increased around energy developments after the construction phase, we calculated an invasives index using Landsat TM and ETM+ imagery for a 34-year time period (1985-2018) and assessed trends for 1,755 wind turbines (from the U.S. Wind Turbine Database) installed between 1988 and 2013 in the southern California desert. The index uses the maximum normalized difference vegetation index (NDVI) for early season greenness (January-June), and mean NDVI (July-October) for the later dry season. We estimated the relative cover of invasive annuals each year at turbine locations and control sites and tested for changes before and after each turbine was installed. These data were used...
Invasion frustration? Can biotic resistance explain the small geographic range of non-native croaking gourami Trichopsis vittata (Cuvier, 1831) in Florida, USA?
In this report, we evaluate this hypothesis for croaking gourami Trichopsis vittata, a non-native species that has established a reproducing population, but has not successfully spread beyond its very small (5 km2) range. We suspected the inability of T. vittata to colonize new habitats may be due to biotic resistance by the native eastern mosquitofish Gambusia holbrooki.

Water temperature models, data and code for the Colorado, Green, San Juan, Yampa, and White rivers in the Colorado River basin
These data were compiled for a manuscript in which 1) we develop a water temperature model for the major river segments and tributaries of the Colorado River basin, including the Colorado, Green, Yampa, White, and San Juan rivers; 2) we link modeled water temperature to fish population data to predict the probability native and nonnative species will be common in the future in a warming climate; and 3) assess the degree to which dams create thermal discontinuity in summer in river segments across the western US. Per goal #1, we developed a water temperature model using data spanning 1985-2015 that predicts water temperature every 1 mile (1.6-km) in rivers both now and in the future due to the potential influence...
Data associated with Sofaer and Jarnevich 'Accounting for sampling patterns reverses the relative importance of trade and climate for the global sharing of exotic plants'
These data were analyzed for the publication 'Accounting for sampling patterns reverses the relative importance of trade and climate for the global sharing of exotic plants': Aim: Exotic species’ distributions reflect patterns of human-mediated dispersal, species’ climatic tolerances, and a suite of other biotic and abiotic factors. The relative importance of each of these factors will shape how the spread of exotic species is affected by ongoing economic globalization and climate change. However, patterns of trade may be correlated with variation in scientific sampling effort globally, potentially confounding studies that do not account for sampling patterns. Location: Global. Methods: We used data from the Global...
A comprehensive list of non-native species established in three major regions of the United States: Version 3.0
Invasive species are a subset of non-native (or nonindigenous) species, and knowing what species are non-native to a region is a first step to managing invasive species. This is the second update to the dataset "First comprehensive list of non-native species established in three major regions of the United States" supporting a USGS Open File Report by the same name published on 2018-10-17. Version 3.0 of the non-native species list, as of 2020-09-15, contains 13,391 records and 11,478 unique names: 537 taxa for Alaska, 5,996 taxa for Hawaii, and 6,818 taxa for the conterminous United States. It is taxonomically refined, has tighter control of establishment status and non-native status, and includes approximate dates...
This dataset describes features of 2941 duck nests that were found in the Prairie Pothole Region of North and South Dakota during 2002-2003. Nest features include estimated initiation date, incubation stage and status as active. The dataset accompanies a scientific journal article describing an evaluation of the density and success of duck nests in conservation fields in 36 study areas that were seeded with native or tame grasses. Field features in this dataset include seeding treatment, planted area, and area of grassland patch.
The Black Acara, Cichlasoma bimaculatum (Linnaeus 1758), first reported as introduced to Florida in 1965, is distributed throughout Florida’s southern peninsula. Examination of live and preserved museum specimens of acara reveal a second species, the Chanchita, Cichlasoma dimerus (Heckel 1840) present in Florida since at least July 2000. A review of the relevant literature coupled with an examination of acara collected in Florida show the Black Acara and the Chanchita are most easily distinguished by number of anal fin spines, body and fin color, caudal fin pattern, and degree of pigment on the rim of the scales of the head and nape. The presence of Cichlasoma dimerus in central Florida springs habitat and the substantial...
This dataset provides location and standard measurements of captured Cuban Treefrogs from the Audubon Park and Zoo area of New Orleans, Louisiana.
Background: The Nonindigenous Aquatic Species (NAS) Database functions as a repository and clearinghouse for the occurrence of nonindigenous aquatic species information from across the United States. The Database contains locality information on more than 1,300 species introduced as early as 1800, including freshwater vertebrates and invertebrates, aquatic plants, and marine fishes. Taxa include both foreign species and North American native species that have been translocated outside of their natural range. Locality data are derived from many sources, including scientific literature; Federal, State, and local natural resource monitoring programs; museum collections; news agencies; and direct submission through...
The proliferation of non-native fishes in Florida is a serious problem, and new species continue to be introduced to the State. Herein we report the eradication of two species of non-native fishes in Miami, Florida (Giant Cichlid Petenia splendida and Blue Mbuna Labeotropheus fuelleborni; both Family: Cichlidae). We removed these fishes before they were observed in the extensive, interconnected canal system through which they may have been able to expand throughout south Florida and access protected areas such as Everglades National Park and Water Conservation Areas.
Non-native marine fishes in Florida: updated checklist, population status and early detection/rapid response data
It has been ten years since the last comprehensive assessment of non-native marine fishes in Florida. Herein, we report sightings of 41 species from Florida coastal waters since the earliest sighting in 1984.

Non-native Asian swamp eel, Monopterus albus/javanensis (Zuiew, 1973/Lacepede, 1800), responses to low temperatures
Asian swamp eel, Monopterus albus/javanensis [Zuiew, 1973/Lacepede, 1800], has been established in the southeastern USA since at least 1994, yet little is known about its ability to survive low winter temperatures. We use standard thermal methodologies to quantify low-temperature responses and provide a detailed description of swamp eel reactions to cold temperatures. When exposed to chronic temperature decreases of 1.0 C per day, swamp eels ceased foraging at 15.0 C, markedly diminished movements below 11.0 C, and became incapacitated near 9.6 C. During critical thermal minima (CTmin) trials, swamp eels exposed to acute temperature drops (0.25 C per minute) tolerated temperatures as low as 6.2 C. Swamp eels exhibited...
Maintaining up-to-date information on non-native organisms’ distributions and species composition can be difficult, especially when species cross jurisdictional boundaries that require interagency coordination. Herein I report on the use of tools that have been used in Florida over the past seven years to assist with tracking of non-native fishes. Ten Fish Slams, where professional biologists and graduate students come together to sample an area for non-native fish, have been held since 2012, which have included nearly 100 individuals from 20 organizations. Participants have sampled nearly 200 unique sites, capturing 36 non-native fish taxa. These activities have generated over 600 records for the U.S. Geological...
