Geolocators, stable isotopes, and citizen science identify migratory timing, route, and spring molt of Smith’s Longspurs Geolocators, stable isotopes, and citizen science identify migratory timing, route, and spring molt of Smith’s Longspurs

Climate change is having a disproportionate impact on the Arctic. For Arctic breeding birds, basic knowledge of their annual cycle, specifically the timing, route, and movement behavior of migration, is needed to understand when and where populations may experience threats. We used a combination of geolocators and stable isotope analysis to identify route and timing of migration in Smith...

Boom and bust: The effects of masting on seed predator range dynamics and trophic cascades Boom and bust: The effects of masting on seed predator range dynamics and trophic cascades

AimSpatiotemporal variation in resource availability is a strong driver of animal distributions. In the northern hardwood and boreal forests of the northeastern United States, tree mast events provide resource pulses that drive the population dynamics of small mammals, including the American red squirrel (Tamiasciurus hudsonicus), a primary songbird nest predator. This study sought to...

Identifying transportation data and system needs for a Federal lands transportation data platform Identifying transportation data and system needs for a Federal lands transportation data platform

Executive Summary Modern transportation and land-use planning efforts include information from many sources to address topics such as safety, efficiency, commercial, and social needs. This wide breadth of topics provides opportunities for collaboration and development of common tools for diverse users. In many cases, different information systems provide the spatial data and geographic...

Assessment of conventional and continuous oil and gas resources in the Lewis Shale in the Southwestern Wyoming Province, Wyoming and Colorado, 2023 Assessment of conventional and continuous oil and gas resources in the Lewis Shale in the Southwestern Wyoming Province, Wyoming and Colorado, 2023

Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean conventional and continuous resources of 294 million barrels of oil and 11 trillion cubic feet of gas in the Lewis Shale in the Southwestern Wyoming Province, Wyoming and Colorado.

Incorporating measurements of vertical land motion in wetland surface elevation change analyses Incorporating measurements of vertical land motion in wetland surface elevation change analyses

We compared elevation trajectories from 14 rod surface elevation table (RSET) stations and 60 real-time kinematic (RTK) global positioning system (GPS) transects within the Blackwater National Wildlife Refuge (BNWR) from 2010–2013. The results were similar, 7.3 ± 0.9 (mean ± standard error; RSET) versus 6.2 ± 0.6 mm year−1 (RTK) (P = 0.216), and were greater than relative sea level rise...

The new self-anchored suspension (SAS) San Francisco Bay Bridge- Its response to a small earthquake The new self-anchored suspension (SAS) San Francisco Bay Bridge- Its response to a small earthquake

This paper presents a summary of previously published work (Celebi 2023) related to the new Self-Anchored Suspension (SAS) bridge that went into service within the last decade as a replacement for the older truss bridge spanning between Yerba Buena Island and Oakland, California, within the San Francisco Bay Area. During the October 19, 1989 M6.9 Loma Prieta earthquake, which occurred...
