PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2025 (ver. 5.0, March 2025) PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2025 (ver. 5.0, March 2025)

Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated...

MODIS Fire Radiative Power data compiled from active fires in Alaska, 2003-2022 MODIS Fire Radiative Power data compiled from active fires in Alaska, 2003-2022

This data release supports the publication: "Linking Fire Radiative Power to land cover, fire history, and environmental setting in Alaska, 2003 - 2022". The *.csv file contains data associated with fire radiative power (FRP) observations derived from 1-km MODIS data over Alaska from 2003 to 2022. The file allows users to replicate the statistical analysis of FRP values with vegetation...

Evaluating changes in Piping Plover home ranges following coastal restoration at Whiskey Island and Caminada Headland, Louisiana from 2013 to 2019 Evaluating changes in Piping Plover home ranges following coastal restoration at Whiskey Island and Caminada Headland, Louisiana from 2013 to 2019

Over time, barrier islands may become eroded and experience land loss, which require management actions to restore island integrity. The process of restoring barrier islands can create new habitats but also alter existing habitats, which can impact the organisms depending on coastal habitats, such as the Endangered Species Act-listed Piping Plover (Charadrius melodus). Therefore, we...

Insights into the formation of thucholites Insights into the formation of thucholites

Thucholites are unique organic features from igneous and sedimentary rocks composed of a U-C-rich interior enclosed by an organic outer shell. Here, we evaluated thucholites from the Ediacaran Salt Range Formation of the Upper Indus Basin in Pakistan using field emission scanning electron microscopy (FESEM) and nanoscale secondary ion mass spectroscopy (NanoSIMS). The thucholites can be...
