Conserving migratory wildlife requires understanding how groups of individuals interact across seasons and landscapes. Telemetry reveals individual movements at large spatiotemporal scales; however, using movement data to define conservation units requires scaling up from individual movements to species- and community-level patterns. We developed a framework...

Comparing maximum likelihood and Bayesian methods for fitting hidden Markov models to multi-state capture-recapture data of invasive carp in the Illinois River
Charles J. Labuzzetta, Alison A. Coulter, Richard A. Erickson
2024, Ecology Movement (12)
BackgroundHidden Markov Models (HMMs) are often used to model multi-state capture-recapture data in ecology. However, a variety of HMM modeling approaches and software exist, including both maximum likelihood and Bayesian methods. The diversity of these methods obscures the underlying HMM and can exaggerate minor differences in parameterization.<h3 class="c-article__sub-heading"...
Widespread chemical dilution of streams continues as long-term effects of acidic deposition slowly reverse
Gregory B. Lawrence, Kevin Alexander Ryan
2024, Environmental Pollution (343)
Studies of recovery from acidic deposition have focused on reversal of acidification and its associated effects, but as recovery proceeds slowly, chemical dilution of surface waters is emerging as a key factor in the recovery process that has significant chemical and biological implications. This...

This paper synthesises current knowledge on selecting appropriate modelling approaches for hydrological restoration projects. The selection of a modelling approach is based...
Environmental and geographical factors influence the occurrence and abundance of the southern house mosquito, Culex quinquefasciatus, in Hawai‘i
Oswaldo Villena, Katherine Maria McClure, Richard J. Camp, Dennis A. LaPointe, Carter T. Atkinson, Helen Sofaer, Lucas Berio Fortini
2024, Scientific Reports (14)
Hawaiian honeycreepers, a group of endemic Hawaiian forest birds, are being threatened by avian malaria, a non-native disease that is driving honeycreepers populations to extinction. Avian malaria is caused by the parasite Plasmodium relictum, which is transmitted by the invasive mosquito Culex quinquefasciatus. Environmental and geographical factors play...

2024, Conservation Biology (38)
Bird populations are declining globally. Wind and solar energy can reduce emissions of fossil fuels that drive anthropogenic climate change, yet renewable-energy production represents a potential threat to bird species. Surveys to assess potential effects at renewable-energy facilities are exclusively local, and the geographic...

The importance of nodal plane orientation diversity for earthquake focal mechanism stress inversions
Jens-Erik Lundstern, Eric Beauce, Orlando J. Teran
2024, Geological Society of London Special Publications (546) 93-118
Inversions of earthquake focal mechanisms are among the most accessible and reliable methods for determining crustal stress. However, the use of this method varies widely, and assumptions that underpin it are often violated, potentially compromising stress estimates. We investigate the consequences of violating the little-studied assumption that the focal mechanisms...

2024, Environmental Science and Technology (58) 1255-1264
Lithium (Li) concentrations in drinking-water supplies are not regulated in the United States; however, Li is included in the 2022 U.S. Environmental Protection Agency list of unregulated contaminants for monitoring by public water systems. Li is used pharmaceutically to treat bipolar disorder, and studies have linked its occurrence in drinking...
Rapid estimation of single-station earthquake magnitudes with machine learning on a global scale
Sydney Dybing, William L. Yeck, Hank M. Cole, Diego Melgar
2024, Bulletin of the Seismological Society of America (114) 1523-1538
The foundation of earthquake monitoring is the ability to rapidly detect, locate, and estimate the size of seismic sources. Earthquake magnitudes are particularly difficult to rapidly characterize because magnitude types are only applicable to specific magnitude ranges, and location errors propagate to substantial magnitude errors. We developed a method for...
Slowly but surely: Exposure of communities and infrastructure to subsidence on the US east coast
Leonard O. Ohenhen, Manoochehr Shirzaei, Patrick L. Barnard
2024, PNAS Nexus (3)
Coastal communities are vulnerable to multihazards, which are exacerbated by land subsidence. On the US east coast, the high density of population and assets amplifies the region's exposure to coastal hazards. We utilized measurements of vertical land motion rates obtained from analysis of radar datasets to evaluate the subsidence-hazard...
