The United States Geological Survey Virginia and West Virginia Water Science Center (USGS VA-WV-WSC) and Fairfax County assembled this data release in support of ongoing USGS VA-WV-WSC monitoring and evaluations of stream conditions overtime of two previously restored, urban-suburban streams in Reston, Virginia – Snakeden Branch and The Glade. The aquatic benthic macroinvertebrate, fish, and habitat sampling and surveying were conducted on the same eight, 100-meter stream reaches (four reaches in Snakeden Branch and four reaches in The Glade) by the USGS VA-WV-WSC. Aquatic benthic macroinvertebrate sampling and physical habitat surveys were conducted in both Spring and Fall of 2021 and a fish survey was conducted in the Summer 2021. Data provided are of five general types: 1. Site locations and characteristics for each of the eight sampling and surveying sites within the two monitored streams; 2. Benthic macroinvertebrate identifications and analytical laboratory results; 3. Fairfax County benthic macroinvertebrate Index of Biotic Integrity (IBI) scores and individual metric results; 4. Fish assemblages, and; 5. Physical habitat measurements. The metadata file “Metadata_for_Reston_Ecological_Data.xml” contains important information pertaining to the attributes of each entity of data, field and laboratory methods, and caveats associated with the Fall benthic macroinvertebrate IBI and metric scores. The "README.txt" file contains a description of each file contained in this data release. This database contains the aquatic benthic macroinvertebrate taxonomic identification and abundance data derived from samples collected at each of the eight total reaches within Snakeden Branch and The Glade in Fall and Spring of calendar year 2021. Samples were collected by the USGS VA-WV-WSC using the Fairfax County standard operating procedures (FCSOP) and specimen identification and abundance calculations were performed by a third-party laboratory. Fairfax County benthic macroinvertebrate IBI scores and individual metrics were calculated by Fairfax County following FCSOP. It is important to note for this data release that the IBI scores presented for Fall samples have caveats associated with them and the ratings (e.g. Excellent, Good, Fair, etc.) for the Fall samples have been intentionally excluded. Please read the methods section of the “Metadata_for_Reston_Ecological_Data.xml” file carefully for further explanation. This data release also contains the fish assemblages data, collected during the Summer of 2021, from the eight total reaches in Snakeden Branch and The Glade. Electrofishing surveys were conducted following FCSOP by the USGS VA-WV-WSC to obtain these results. Finally, this data release contains the physical habitat data surveyed in both Fall and Spring of 2021. Multiple habitat metrics were measured throughout each of the eight total reaches on Snakeden Branch and The Glade.

Guam community members gathered macroinvertebrate within a 25-meter x 2-meter belt transect. Members identified macroinvertebrates to species (when possible), including echinoderms, mollusks, and crustaceans. Data is supported by photos from the sites. Surveys record total number of macroinvertebrates per 50 square meters for each transect.

This dataset details the findings of a series of freshwater surveys for macroinvertebrates, periphyton and plankton in selected sub-catchments of the Ba River (Viti Levu, Fiji) that were conducted in 2019. The survey was funded under the Fiji Global Environment Facility 5 System for Transparent Allocation of Resources Ridge to Reef project.

The sub-catchments surveyed were Waimanu, Waisali, Nadrou, Navisa, Nakara and Nabiarua. A list of targeted taxon was first compiled and investigated across all sites. The results of the surveys are presented here as presence and absence records.

The State of Hawaii DLNR (Department of Land and Natural Resources) DAR (Division of Aquatic Resources) marine monitoring team conducted surveys for fish and large mobile invertebrates along the West Hawaii coastline. Data were recorded along 5x25 meter transects at random sites going as far south as Manuka and as far North as Upolu Point. Data collection for one transect was completed at each site. Data are provided as individual observations noting species, quantity, and size of fish and species and quantity of invertebrates.

The sites have been selected to match the 2 following criteria: shortest time-serie is 10 years and the smallest number of sample occasions is 8 (sampling_date). Coordinates of sampling points are WGS84 decimal degrees (X_coordinate, Y_coordinate).

Macroinvertebrate and water chemistry data collected as part of the NCRN Biological Stream Monitoring Proocol. All data were collected during the Spring sampling season. In 2005, the National Capital Region Inventory and Monitoring Network (NCRN) initiated a long-term water quality and quantity monitoring program, funded in part by the National Park Service Water Resources Division. The Biological monitoring portion of the program is carried out every 6 years at 37 sites within 10 of the NCRN parks. The data collected using this protocol will provide much needed baseline information on the stream biological resources in the NCRN, particularly in terms of community structure and composition. The information will also be used to determine long term trends in community composition, as well as trends in the abundance and distribution of individual species. Macroinvertebrate and water chemistry data collected as part of the NCRN Biological Stream Monitoring Proocol. This data set incldues macroinvertebrate taxa lists from all streams sampled as well as water quatlity data collected at those streams. In addition, macroinvertebrate data were used to calculate an benthic index of biotic integrity (B-IBI) that can be used to assess the health of the stream based on the macroinvertebrate populations. All data were collected during the Spring sampling season.

The Macroinvertebrate survey is conducted by the Murray?Darling Fresh Water Research Centre (MDFRC) on behalf of the Murray?Darling Basin Authority to provide long term baseline biological datasets for eight specified locations in the Murray River and four specified locations in the Mitta Mitta River.

Friends of Reef Guam is a community monitoring project that trains members as citizen scientists to build local capacity in identification of species. From February 2013 through October 2019, members gathered benthic and macroinvertebrate cover in specific areas identified on Guam. During benthic surveys, members identified corals, algae, seagrass, sponges and macroinvertebrates. Identification of macroinvertebrates was collected by members as well through species, including; echinoderms, mollusks, and crustaceans. Data is supported by photos from the sites.

Food availability varies considerably over space and time in wetland systems, and consumers must be able to track those changes during nutrient demanding points in the life cycle like breeding. Resource tracking has been studied frequently among herbivores, but receives less attention among consumers of macroinvertebrates. We evaluated the change in resource availability across habitat types and time, and the simultaneous density of waterfowl consumers throughout their breeding season in a high-elevation, flood-irrigated system. We also assessed whether the macroinvertebrate resource density better predicted waterfowl density across habitats, compared to consistency (i.e., temporal evenness) of the invertebrate resource or taxonomic richness. Resource density varied marginally across wetland types but was highest in basin wetlands (i.e., ponds) and peaked early in the breeding season, whereas it remained relatively low and stable in other wetland habitats. Breeding duck density was positively related to resource density, more so than temporal resource stability, for all species. Resource density was negatively related to duckling density, however. These results have the potential to not only elucidate mechanisms of habitat selection among breeding ducks in flood-irrigated landscapes, but also suggest there is not a consequential trade-off to selecting wetland sites based on energy density versus temporal resource stability and that good-quality wetland sites provide both. Methods Macroinvertebrate Data Collection We collected nektonic invertebrate samples using 2-L activity traps in 2020 and 2021 (Murkin et al. 1983). We placed traps at randomly-selected points within 40 wetland sites that encompassed the five different wetland habitats. The sites we sampled in four of the wetland habitats (basin wetlands, riparian wetlands, irrigation ditches, and flooded hay meadows) spanned three individual properties, including two private ranches and Arapaho NWR (Figure 1). We also sampled three public reservoirs across the study area. We selected three random wetlands of each type on each of the three properties, and three random sampling points within each selected wetland with the exception of reservoirs. We randomly selected two 200-m length plots of shoreline in each reservoir and three random points within each plot to sample (Cooper and Anderson 1996, de Szalay et al. 2003, Behney 2020). In total, we deployed 126 traps during each sampling occasion (3 properties x 4 wetland habitats x 3 sampled wetland sites of each variety x 3 sampled points in each wetland) = 108 samples, + (3 reservoirs x 2 plots in each reservoir x 3 points in each plot = 18 samples). Traps remained in the wetlands for 48 hours every fourteen days, resulting in six sampling occasions each year over the course of the breeding season (13 May through 22 July). No traps were placed if the wetland was dry on a given sampling occasion, and that status was noted and aquatic invertebrate resource density was treated as a zero for that occasion. In the event that a wetland was not flooded or less flooded during the second year of sampling (2021), we randomly selected new points within the new boundary of the same wetland and treated those sampling points as unique from the original locations, but nested within the same site. Occasionally traps became dislodged and either went missing or floated to the surface, in which case we replaced traps and allowed them to remain in the wetland for the subsequent 48 hours. Activity traps had a 15 cm opening at the widest part of the funnel and a 2 cm opening at the narrowest part of the funnel. We placed them so that the top of the widest part of the funnel was approximately 1 cm above the surface of the water to capture invertebrates in the part of the water column in which dabbling ducks most often forage (Guillemain et al. 2000, Behney 2020). Upon collection, traps were emptied into a mesh sieve-bottom bucket. All individual invertebrates from the sample were placed into plastic storage cups and stored in 70% ethanol until processing. We emptied each sample into a 0.355 mm (number 45) gauge mesh sieve in a wet lab and moved all individuals to a Petri dish for identification and counting (Behney 2020). We placed samples under a dissecting microscope (AmScope SM-1BSY-64S Stereo Zoom Microscope) and identified individuals to taxonomic Family when possible. Any sample containing more than 1000 individuals of a given Family was subsampled by 16.6% using a 6 x 6 square gridded Petri dish (Williams et al. 2014, Behney 2020). We counted individuals in a random subset of six of the 36 cells and multiplied by six to estimate the total number of individuals of that Family in the sample. Waterfowl Data Collection We conducted breeding pair counts of ducks on the same wetland sites being sampled for macroinvertebrates (n=40) using a dependent double-observer methodology during the breeding seasons of 2020 and 2021 (Nichols et al. 2000). Pair count survey timing coincided with the first three macroinvertebrate sampling occasions. A primary observer counted every individual dabbling and diving duck observed and reported the number to a secondary observer, who recorded data while also recording any observations missed by the primary observer (Roy et al. 2021). We restricted the dataset to the four most common species of breeding ducks in our study system, which included cinnamon teal (Spatula cyanoptera), gadwall (Mareca strepera), mallard (Anas platyrhynchos), and lesser scaup (Aythya affinis). Although we used the standard pair count practice of separating lone drakes from paired ducks in each count to identify breeding phenology and thus the timing of our first invertebrate sampling occasion, we used the total count of breeding ducks for the purposes of evaluating the relationship between duck density and invertebrate availability. In addition, few individuals were missed by the primary observer (i.e., detection probability was high), so we pooled observed drakes and hens of a given species to give us a site- and occasion-specific count. Brood surveys also occurred on the sites sampled for macroinvertebrates, but followed an independent double-observer methodology during 2020-2021 (Nichols et al. 2000, Vrtiska and Powell 2011). Both observers counted the number of ducklings they observed and subsequently compared observations to determine whether they had been observing the same brood and compare the number counted. The smaller number of ducklings commonly observed at one time allowed for accurate count comparisons between observers (Pagano and Arnold 2009). The timing of counts coincided with the latter three macroinvertebrate sampling occasions. Observers counted all ducklings within a given brood and identified their age class according to Gollop and Marshall (1954). Observers spent a minimum of ten minutes at each wetland site and conducted surveys using window- or tripod-mounted spotting scopes and binoculars to allow time for hidden broods to become visible (Pagano and Arnold 2009, Walker et al. 2013). We restricted the dataset to ducklings of the same four duck species listed above, and pooled the total number of ducklings for a given species, site, and occasion.

Freshwater and Marine Biological Surveys England. The Environment Agency undertakes freshwater and marine biological monitoring in England. Freshwater and Marine Biological Surveys England is a large dataset containing taxonomic level species data for biological surveys carried out in freshwater and marine environments. Species surveys include: • Invertebrate, algal and macrophyte surveys in rivers and still waters; • Marine macro-invertebrate, algal, macrophyte and seagrass data.

Note: - This archive is more commonly known as BIOSYS - This dataset contains Freshwater, River and Lake Macroinvertebrate surveys only. - Pollution Samples are excluded from the dataset. - The species LIFE calculations in this dataset are known to include some small errors. Each calculation was correct at the time the record was saved. However, as corrections are made to taxon values and taxa hierarchy within Biosys, the calculations are not automatically updated. This is a system constraint that we are unable to fix quickly, however we will be working this year (2018) to try and resolve it.
