Data and Shapefiles for the Potentiometric Surface of the South Coast Aquifer and Hydrologic Conditions in the Santa Isabel area, Puerto Rico, March-April 2014

A groundwater level survey and reconnaissance of the hydrologic conditions in the South Coast aquifer in the Santa Isabel area of southern Puerto Rico was conducted during March 31 to April 17, 2014. The field survey included groundwater level measurements at 55 wells and instantaneous streamflow measurements at 15 locations in streams and irrigation canals. A potentiometric surface map of the alluvial aquifer provides an indication of the directions of groundwater flow. The objective of the field survey was to delineate the potentiometric surface of the study area defined as the South Coast aquifer between the Río Descalabrado to the west and the Río Jueyes to the east of the town of Santa Isabel. Instantaneous streamflow measurements were made at selected sites along the Río Coamo, Río Descalabrado, Río Cañas, and the Canal de Juana Díaz to evaluate groundwater and surface-water interactions during the synoptic survey. Potentiometric contours are based on water-level measurements collected at wells during the dry season from March 31 to April 17, 2014. Measured values of the potentiometric surface ranged from -22.80 feet to 185.4 feet above mean sea level. The results of the study indicate a cone of depression in the aquifer near the center of the study area, where the potentiometric surface is below mean sea level.

Data release for Quantifying ecosystem service flows at multiple scales across the range of a long-distance migratory species

Migratory species provide ecosystem goods and services throughout their annual cycles, often over long distances. Designing effective conservation solutions for migratory species requires knowledge of both species ecology and the socioeconomic context of their migrations. We present a framework built around the concept that migratory species act as carriers, delivering benefit flows to people throughout their annual cycle that are supported by the network of ecosystems upon which the species depend. We apply this framework to the monarch butterfly (Danaus plexippus) migration of eastern North America by calculating their spatial subsidies. Spatial subsidies are the net ecosystem service flows throughout a species’ range and a quantitative measure of the spatial mismatch between the locations where people receive most benefits and the locations of habitats that most support the species. Results indicate cultural benefits provided by monarchs in the U.S. and Canada are subsidized by migration and overwintering habitat in Mexico. At a finer scale, throughout the monarch range, habitat in rural landscapes subsidizes urban residents. Understanding the spatial distribution of benefits derived from and ecological support provided to monarchs and other migratory species offers a promising means of understanding the costs and benefits associated with conservation across jurisdictional borders.

Created snag characteristics and cavity-nesting bird associations in the CFIRP stands, McDonald-Dunn Research Forest, Corvallis, OR, USA, 2016

Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function and structure of created snags across long time periods (&gt;20 years) is absent from the literature. Using snags that were created by topping mature Douglas-fir trees (Pseudotsuga menziesii) as part of the OSU College of Forestry Integrated Research Project, we measured characteristics of 731 snags and quantified foraging and breeding use of snags by birds 25-27 years after their creation. We also examined whether different harvest treatments (i.e., group selection, two-story, clearcut) and snag configurations (i.e., scattered and clustered) influenced snag characteristics or avian use for foraging and nesting. In addition, we conducted point count and call play-back surveys to calculate naive occupancy estimates for cavity-nesting bird species.

Topographic Survey Data from Photogrammetry of Fountain Creek between Colorado Springs and the Confluence of Fountain Creek at the Arkansas River, Colorado, 2017

In 2012, the U.S. Geological Survey (USGS) Colorado Water Science Center in cooperation with Colorado Springs Utilities selected 10 reaches or study area along Fountain Creek between Colorado Springs and the confluence of Fountain Creek at the Arkansas River for annual bed and bank characterization and topographic surveys.  The 10 selected study areas are approximately 5 to 20 bank-full channel widths in length.  The topographic surveys collected point data of location and elevation in the active channel and along both left and right banks and flood plains.  Historically, the topographic data have been collected exclusively using real-time kinematic Global Navigation Satellite Systems.  However, on January 12, 2017, at Study Area 3, the topographic survey data were collected with a 3DR Solo Unmanned Aircraft System using structure from motion photogrammetry.  These point data will be compared to real-time kinematic Global Navigation Satellite Systems which also was collected at Study Area 3 in 2017.  The new topographic survey data will allow UGSG to evaluate the utility and functionality of using drone collected data in support of the an annual assessment of the geomorphic change at each study area.  These data have been georeferenced but have not had any additional processing to remove vegetation or other obstructions.  Work is underway to generate a bare-earth model that has all vegetation and other erroneous points removed.

Meristic and morphometric data for "Revision of the jawfish genus Lonchopisthus with description of a new Atlantic species (Teleostei: Opistognathidae)"

Synonymies, diagnoses, descriptions, illustrations, an identification key and meristic frequency tables are provided for all species of Lonchopisthus. Most of the skeletal anatomy of L. higmani is also illustrated. A new jawfish, Lonchopisthus ancistrus n. sp., is described from the Gulf of Mexico and off Honduras based on 21 specimens 41‒89 mm standard length (SL). It differs from other congeners by the following combination of characters: posterior end of maxilla strongly hooked; membrane connecting maxilla and premaxilla and inner membrane covering posterior part of dentary pale; segmented dorsal-fin rays 11–13, with unbranched rays 2–5; longitudinal body scale rows 33‒39; and very long pelvic fins, 39.4‒75.3 % SL. Lonchopisthus lemur (and its synonym L. meadi) share most characters with L. ancistrus but differ in having shorter pelvic fins, 19.2‒29.9 % SL; fewer longitudinal body scale rows, 26‒33; and five infraorbitals. Both are relatively deep-water species occurring from 100 to at least 375 m, while the other species are found in 3‒139 m. Lonchopisthus micrognathus is unique in having no branched caudal-fin rays at any size and the middle caudal-fin rays with free tips that may be used to maintain tactile contact with the substrate while hovering over its burrow. The western Atlantic Lonchopisthus higmani and eastern Pacific L. sinuscalifornicus are sister species that differ from the other Atlantic species in having the posterior end of the maxilla with a notch instead of a strong hook, opercle with a large dark blotch, and one supraneural (vs. no supraneural).

Bankfull polygon coverage of Lower Missouri River

Shapefile created by USGS. This is a channel polygon coverage digitized from aerial photography at the top of the high bank. The low-altitude aerial orthophotos were provided by the US Army Corps of Engineers and were acquired 11/1/2012  to 11/21/2012 under leaves off and relatively low-water conditions. Notably, these conditions post-date 2011 flooding and channel changes. The features digitized correspond to the interpreted high bank, or bankfull conditions. Types of channel polygons were also discriminated: main channel, side channel chutes, islands, backwaters, and irregular off-channel aquatic features.

New record of California red-legged frog (Rana draytonii) in Whitewater Canyon, Riverside County, CA, USA

In February 2017, a population of California red-legged frog Rana draytonii was discovered in the southern foothills of the San Bernardino Mountains of Riverside County, California, near the edge of the species’ historic distribution. A few days after the first sightings of R. draytonii at the Whitewater Preserve, we conducted a visual daytime search for frogs, tadpoles and egg masses followed by a nighttime eye shine search for adult frogs. The captured frog weighed, measured (snout-to-urostyle [SU]), sampled for tissue and georeferenced using a GPS unit. Survey work was authorized by a U.S. Fish and Wildlife Service Recovery Permit and a California Department of Fish and Wildlife Scientific Collecting Permit.
To better understand the origin of these frogs, we extracted DNA from a small toe clip using a Qiagen® DNeasy Kit (Qiagen Inc., Valencia CA) and Sanger-sequenced a region of the cytochrome b mitochondrial gene (986 base-pairs) that has been used to good effect for identifying regionally specific 67 mtDNA clades (Richmond et al. 2014). Sequencing was performed on a 3730xl DNA Analyzer at Genewiz (La Jolla, CA). We used DnaSP 5.10 (Librado &amp; Rozas 2009) to match the haplotype sequence against a large cytochrome B database representing the full range of R. draytonii.

Evaluating upstream passage and timing of approach by adult bigheaded carps at a gated dam on the Illinois River:Data

To evaluate how bigheaded carps move upstream through and around Starved Rock Lock and Dam (SRLD) on the Illinois River, their movements were monitored using acoustic telemetry. This dataset describes the results of this study and was used to compare the residency duration of upstream migrants downstream of SRLD between years, tailwater elevation, and water temperature, and how tailwater elevation and water temperature influenced their timing of arrival downstream of SRLD. Calculation of passage and residency are available in the thesis of Matthew Lubejko (Southern, Illinois University, 2016).

Lake Erie, Western Basin Aquatic Vegetation

Observations and subtle shifts of vegetation communities in western Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities.  Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities and establish baseline conditions for assessing future effects.  Existing aerial imagery was used with object-based image analysis to detect and map aquatic vegetation in the western basin of Lake Erie.

Diets of Silver Chub (Macrhybopsis storeriana) in western Lake Erie, 2014

Diet and estimated ages of Silver Chub (Macrhybopsis storeriana) collected by the US Geological Survey in western Lake Erie in 2014 are presented. Fish were frozen in the field at -20 C and dissected in the lab. Ages were estimated by one experienced biologist who estimated ages twice, then reconciled age estimates when the two age estimates differed. Diet taxa were enumerated, dried individually at 60 F until stable weight was achieved (~24-48 hrs), then weighed. Zero weights for non-zero counts indicates dry weight was below detection limit of the scale used.

Evidence of Asian carp spawning above a key choke point in the Mississippi River: Data

Bighead Carp, Silver Carp and Grass Carp (collectively Asian carp) were introduced to North America in the 1960s and 70s and have established in the lower Mississippi River basin.  Previously published evidence for spawning of these species has been limited in the upper Mississippi River to just below Dam 22 (near Saverton, MO).  In 2013 and 2014, we sampled ichthyoplankton at 18 locations in the main stem of the upper Mississippi River from Dam 9 through Dam 19 and in four tributary rivers that empty into the Mississippi River (Des Moines, Skunk, Iowa and Wisconsin Rivers).  We identified eggs and larvae using morphological techniques and then used genetic tools to confirm species identity.  The spawning events we observed often included more than one species of Asian carp and in a few cases included eggs that must have been derived from more than one upstream spawning event.  The upstream extent of genetically confirmed Grass Carp was Pool 12, while Bighead Carp and Silver Carp were observed in Pool 16.  In all these cases, ichthyoplankton likely drifted downstream for several kilometers prior to collection.  As has been observed elsewhere, no eggs or larvae were collected prior to water temperature reaching 17°C and discharge was usually high when eggs or larvae were observed.  Several major spawning events were observed in 2013, but not in 2014.  Although reproduction appears to be occurring for all three of these species above Dam 19, the recruitment success of these populations is unknown.

Food-web structure of canyon and slope associated fauna revealed by stable isotopes

The primary objective of this study was to assess deepsea food web structure and trophic niches in Baltimore and Norfolk canyons, the adjacent slopes, and chemosynthetic seeps along the mid-Atlantic margin using stable isotope analyses (SIA) and isotope niche width analysis.  We hypothesized that the isotopic compositions of canyon versus slope fauna would be distinct, given differences in the physics and chemistry of the canyons and slopes and resulting quality and quantity of the organic matter available to the benthos.  These differences should be evident across taxa and among and within feeding groups.  We also used SIA to estimate trophic positions of invertebrates and fishes and to examine changes in trophic level with size for specific demersal fish species.  Furthermore, comparisons were made between results from SIA for select fishes and stomach content analyses to characterize trophic relationships of fishes over time.
