Stream restoration produces transitory, not permanent, changes to fish assemblages at compensatory mitigation sites

open access: yesRestoration Ecology, Volume 31, Issue 5, July 2023., 2023
There is inconsistent evidence that stream restoration projects lead to recovery of ecosystem attributes, especially stream biota. While some assessments have documented desired changes in fish community metrics in the first years following restoration, longer‐term studies have not always corroborated these findings.

Diverse migratory portfolios drive inter‐annual switching behavior of elk across the Greater Yellowstone Ecosystem

open access: yesEcosphere, Volume 14, Issue 5, May 2023., 2023
Abstract A growing body of evidence shows that some ungulates alternate between migratory and nonmigratory behaviors over time. Yet it remains unclear whether such short‐term behavioral changes can help explain reported declines in ungulate migration worldwide, as opposed to long‐term demographic changes.

Changes in wildfire occurrence and risk to homes from 1990 through 2019 in the Southern Rocky Mountains, USA

open access: yesEcosphere, Volume 14, Issue 2, February 2023., 2023
Abstract Wildfires and housing development have increased since the 1990s, presenting unique challenges for wildfire management. However, it is unclear how the relative influences of housing growth and changing wildfire occurrence have altered risk to homes, or the potential for wildfire to threaten homes. We used a random forests model to predict burn

Trends in tree cover change over three decades related to interannual climate variability and wildfire in California

open access: yesEnvironmental Research Letters, 2023
The U.S. State of California has experienced frequent drought events, hotter temperatures and other disruptions to the climate system whose effects on ecosystems have been widely reported in recent decades.

Design-based mapping of land use/land cover classes with bootstrap estimation of precision by nearest-neighbour interpolation [PDF]

open access: yes, 2023
Land use/land cover mapping is usually performed by classifying satellite imagery (e.g., Landsat, Sentinel) for the whole survey region using classification algorithms implemented with training data.

An SOA‐Based Model for the Integrated Provisioning of Cloud and Grid Resources

open access: yesAdvances in Software Engineering, Volume 2012, Issue 1, 2012., 2012
In the last years, the availability and models of use of networked computing resources within reach of e‐Science are rapidly changing and see the coexistence of many disparate paradigms: high‐performance computing, grid, and recently cloud. Unfortunately, none of these paradigms is recognized as the ultimate solution, and a convergence of them all ...

Building a Federated Data Catalog with Client Implementations - Meeting Data Where It is

open access: yes, 2023
Much of the dialog and technical advancement surrounding the use of earth observation data is centered on data creators and providers, whose official responsibilities end at data delivery.

Machine Learning Analysis of Streamflow Recession Patterns Across Climates in the Contiguous United States

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract Streamflow recession analysis aims to understand the controls on low‐flow dynamics in catchments. Traditionally, this involves analyzing baseflow Q and its time derivative dQ⁄dt on log‐log plots, often revealing power‐law relationships. The slope of these power laws has been interpreted through hydraulic groundwater theory.

Impacts of Land Cover Change on Urban Heat Island (UHI) in Denver from 1985 to 2020 [PDF]

open access: yes, 2023
Rapid urbanization due to land use and land cover change has become one of the major problems in the fastest-growing cities during the past few decades. Land surface temperature has changed dramatically due to urban expansion, and it is a major driver of

Estimating changes in streamflow attributable to wildfire in multiple watersheds using a semi‐distributed watershed model

open access: yesEcohydrology, Volume 17, Issue 7, October 2024.
Abstract More than half of water supply in the western United States is sourced from forested lands that are increasingly under wildfire risk. Studies have begun to isolate the effects of wildfire on streamflow, but they have typically used coarse temporal resolutions that cannot account for the numerous, interconnected watershed processes that control
