Stable isotope dynamics of herbivorous reef fishes and their ectoparasites: 2012, 2013, 2018 Stable isotope dynamics of herbivorous reef fishes and their ectoparasites: 2012, 2013, 2018
Acanthurid surgeonfishes are an abundant and diverse group of herbivorous fishes on coral reefs. While their contribution to trophic linkages and dynamics in coral reef systems has received considerable attention, the role of linkages involving their parasites has not. As both consumers of fish tissue and prey to microcarnivores, external parasites can play a significant role in trophic...

These datasets provide: 1) field-collected biomass and structural attributes for coastal salt marsh in the Port Fourchon area, Louisiana; 2) simulated biomass and structural attributes along flooding gradients using mixed model regression outputs; and 3) resilience metrics calculated using multivariate hypervolumes along with potential environmental covariates of resilience metrics.
Mark-recapture data for a boreal toad metapopulation at the Lost Trail National Wildlife Refuge, Montana (2003-2018) Mark-recapture data for a boreal toad metapopulation at the Lost Trail National Wildlife Refuge, Montana (2003-2018)
From 2003-2018, USGS researchers and collaborators conducted mark-recapture studies of the boreal toad at the Lost Trail National Wildlife Refuge in northwestern Montana, USA. The datasets included here contain information on individual toad capture history, body size, and disease status. These data were collected annually over the 16-year period at up to 11 breeding sites per year on...
Environmental DNA (eDNA) and Fish Capture Data from Round Goby Screening Surveys on the Eastern Erie Canal, New York (ver. 3.0, February 2026) Environmental DNA (eDNA) and Fish Capture Data from Round Goby Screening Surveys on the Eastern Erie Canal, New York (ver. 3.0, February 2026)
The dataset is composed of four tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) at 12 sites on the Eastern Erie Canal in New York between Oneida Lake and the Hudson River from 2016 to 2025. The sampling techniques and frequency of sampling were adapted over time to optimize the efficiency of the study effort. From 2016-2019 eDNA...
Near-surface geophysical data collected in the Sunflower Drain study area near Delta, Colorado, March 2018 Near-surface geophysical data collected in the Sunflower Drain study area near Delta, Colorado, March 2018
Near-surface geophysical surveys were conducted during March 2018 in an irrigated agricultural drainage near Delta, Colorado, locally know as Sunflower Drain. This data release presents results of two surveys, one using fiber-optic distributed temperature sensing (FO-DTS) and the second using a horizontal-to-vertical spectral ratio (HVSR) passive seismic method. For the FO-DTS, a...
