Greater Sage-Grouse Habitat Selection, Survival, Abundance, and Space-Use in the Bi-State Distinct Population Segment of California and Nevada Greater Sage-Grouse Habitat Selection, Survival, Abundance, and Space-Use in the Bi-State Distinct Population Segment of California and Nevada
Greater sage-grouse (Centrocercus urophasianus; hereinafter sage-grouse) is a sagebrush obligate species and widely considered an indicator species for sagebrush ecosystems and other sagebrush-dependent species (Hanser and Knick, 2011; Prochazka and others, 2023). Sagebrush ecosystems are threatened by a wide range of disturbances and anthropogenic factors, including climate change...
Whole rock and micro-analytical geochemistry of minerals, melt inclusions, and matrix glasses from Kapoho Crater and Puʻulena Crater, Kīlauea Volcano, Hawaiʻi Whole rock and micro-analytical geochemistry of minerals, melt inclusions, and matrix glasses from Kapoho Crater and Puʻulena Crater, Kīlauea Volcano, Hawaiʻi
Kilauea volcano (Hawaii, USA) is a shield volcano that exhibits both effusive and explosive eruptive activity. Although Kilauea has been predominantly built through effusive eruptions, explosive eruptions have occurred repeatedly at both Kilauea's summit and in the volcano's lower East Rift Zone (Moore, 1992; Swanson et al., 2014). This dataset presents geochemical analyses of samples...
Floodplain Inundation Model and Inundation Depths: Upper Mississippi and Illinois Rivers Floodplain Inundation Model and Inundation Depths: Upper Mississippi and Illinois Rivers
Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS), which comprises the Upper Mississippi and Illinois Rivers. Here, we present a series of related data products supporting floodplain inundation modeling of the UMRS. First, raster files comprise a unique identifier, river mile...
Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023 Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023
Bighorn sheep (Ovis canadensis) were frequently photographed by wildlife cameras when they visited desert tortoise (Gopherus agassizii) burrows in the eastern San Bernardino Mountains near Palm Springs, California, USA (Mesa Windfarm). A previous study suggested that sheep may have been utilizing the excavated spoil material from burrows as a mineral lick. We aimed to test this...
Loggerhead Iridium Locations in Northwest Florida 2019-2021 Loggerhead Iridium Locations in Northwest Florida 2019-2021
This dataset is comprised of times, locations, and water temperatures collected from iridium satellite tags attached to 11 loggerhead sea turtles between 2019 and 2021.
Aquatic Stable Isotopes in the Owens River Gorge, CA 2017-2021 Aquatic Stable Isotopes in the Owens River Gorge, CA 2017-2021
This dataset includes stable nitrogen-15 and carbon-13 isotope analysis data derived from freshwater aquatic and semi-aquatic primary producers, invertebrates, and fishes collected from five sampling sites (and one pilot site) within the Owens River Gorge, Mono and Inyo counties, CA, USA between 2017 and 2021. These sampling efforts were conducted in conjunction with the California...
