Susan Wherry, Liam N. Schenk
2024, Water (4) 1073-1082
Two independent machine learning techniques, boosted regression trees and artificial neural networks, were used to examine the physicochemical and meteorological variables that affect the seasonal growth and decline of harmful algal blooms (HABs) in a shallow, hypereutrophic lake in southern Oregon. High temporal resolution data collected...
Identifying indicators of polar bear population status
Karyn D. Rode, Ryan R. Wilson, Justin A. Crawford, Lori T. Quakenbush
2024, Ecological Indicators (159)
Monitoring trends in large mammal populations is a fundamental component of wildlife management and conservation. However, direct estimates of population size and vital rates of large mammals can be logistically challenging and expensive. Indicators that reflect trends in abundance, therefore, can be valuable tools for...

Cameron L. Aldridge, D. Joanne Saher, Julie A. Heinrichs, Adrian P. Monroe, Matthias Leu, Steve E. Hanser
2024, Land (13)
Biodiversity is threatened due to land-use change, overexploitation, pollution, and anthropogenic climate change, altering ecosystem functioning around the globe. Protecting areas rich in biodiversity is often difficult without fully understanding and mapping species’ ecological niche requirements. As a result, the umbrella species concept is often applied, whereby conservation of...

Recent increases in annual, seasonal, and extreme methane fluxes driven by changes in climate and vegetation in boreal and temperate wetland ecosystems
Sarah Feron, Avni Malhotra, Sheel Bansal, Etienne Fluet-Chouinard, Gavin McNicol, Sarah Knox, Kyle Delwiche, Raul Cordero, Zutao Ouyang, Zhen Zhang, Benjamin Poulter, Robert B. Jackson
2024, Global Change Biology (30)
Climate warming is expected to increase global methane (CH4) emissions from wetland ecosystems. Although in situ eddy covariance (EC) measurements at ecosystem scales can potentially detect CH4 flux changes, most EC systems have only a few years of data collected, so temporal trends in CH4 remain uncertain. Here, we use established drivers to...

2024, Toxics (12)
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous and persistent environmental contaminants originating from many everyday products. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are two PFAS that are commonly found at high concentrations in aquatic environments. Both chemicals have previously been shown to be toxic to fish, as...

Hao Dong, Kai Sun, Gary D. Egbert, Anna Kelbert, Naser Meqbel
2024, Computers and Geosciences (184)
The Curl-Curl equation is the foundation of time-harmonic electromagnetic (EM) problems in geophysics. The efficiency of its solution is key to EM simulations, accounting for over 95% of the computation cost in geophysical inversions for magnetotelluric or controlled-source EM problems. However, most published EM...
