Surveys for immature life stages of the Samoan swallowtail butterfly (Papilio godeffroyi) were conducted on 117 individually marked host trees (Micromelum minutum) in eight forest stands on Tutuila Island, American Samoa, at approximately monthly intervals during 2013-2014. The eight stands were mostly in or adjacent to the National Park of American Samoa (NPSA), but one stand was...

This dataset contains sample collection information and microsatellite genotype data for Northern Black Swifts in 6 colonies across Colorado, New Mexico and Idaho. This data was collected to examine levels of genetic diversity and connectivity among Black Swift colonies and also to assess parentage at a subset of those sites. This study helps clarify the breeding system of the Black...

At 11:21 p.m. (Hawaii Standard Time [HST]) on November 27, 2022, Mauna Loa volcano on the Island of Hawaiʻi started erupting from fissures at its summit caldera, Mokuʻāweoweo. This was followed shortly afterwards by the opening of a segment of fissures in the direction of the Southwest Rift Zone. These were mostly within the structural boundary of the caldera, so their location is...

The potential introduction of SARS-CoV-2, the virus responsible for the COVID-19 pandemic, into North American bat populations is of interest to wildlife managers due to recent declines of several species. Populations of little brown bats (Myotis lucifugus) have collapsed due to white-nose syndrome (WNS), a disease caused by the introduction and spread of the fungal pathogen...

Data sets containing: (1) sampling information and equipment, (2) precipitation and air temperature data from Iowa counties containing wetlands sampled, (3) water quality measurements from Iowa wetlands sampled, (4) quality assurance quality control sample result information, and (4) similarities between the highly pathogenic H5N1 virus water sequence and other highly pathogenic avian...

Data presented are results of vegetation sampling conducted in 2019-20 and 2023 in 24 survey plots to document the status of infestation by shot hole borers (Euwallacea sp.) on the riparian vegetation at the San Diego River. This dataset presents location, percent cover of different vegetation types, and number of seedlings for each survey plot. In addition, for each tree and sapling in...

From late December 2022 to January 2023, a series of atmospheric river storms produced widespread landsliding in the San Francisco Bay area of California. USGS scientists performed reconnaissance field work to document the extent of landsliding in the region and compiled reports of landslides from media and California Highway Patrol (CHP) reports. This data release documents locations of...

Adult female San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) were captured and examined using an ultrasound device to determine if they were gravid and count the number of embryos in those that were. Morphological data including length and mass were collected for each snake, along with the date of capture and a study site identifier. These data support the following...

This dataset includes 2022 reach fish data and reach habitat data collected to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcutti) in the Santa Ana River, California.

This study evaluated sap flow of neotropical mangrove species subjected to background nutrient loading, and well as fertilization with either nitrogen or phosphorus, at Ding Darling National Wildlife Refuge (NWR). Data collections were made seasonally to model stand water use by mangrove forests as a metric of ecosystem stress through alteration of water use potential at the stand level...

These data support a sap flow study, as represented by dual temperature differentials between heated and unheated probes inserted into trees. Data are from two separate field sites, with five tree species recorded every 30 minutes during the time periods of June 29 to August 24, 2008, and March 5 to June 1, 2009. Data were collected from a longleaf pine plantation (Pinus palustris) and a

The Software Application for SMASH (Spectral Mixture Analysis for Surveillance of Harmful Algal Blooms), or SAS for short, is an application to facilitate mapping of potentially harmful algal blooms in reservoirs, rivers, and lakes from remotely sensed data. More specifically, SAS is designed to exploit the detailed observations of reflectance available within a hyperspectral image to...
