Elinor S. Meredith, Susanna F. Jenkins, Josh L. Hayes, Denny J. Chee, David Lallemant, Natalia I. Deligne, Stravos Meletlidis, Alicia Felpeto
2025, International Journal of Disaster Risk Reduction
Fragility functions are vital tools in volcanic risk assessments to evaluate the probability of damage to structures at given hazard intensities. Traditionally, lava flow damage is assumed to be binary, whereby in contact with lava results in complete destruction and not in contact with lava remains undamaged. However, past studies present...

James William Atterholt, Jeffrey J. McGuire, Andrew J. Barbour, Connie Stewart, Morgan P. Moschetti
2025, Science (389) 1361-1365
Fault structure and rupture physics are deeply intertwined, and observations of this coupling are critical for understanding earthquake behavior. Rupture propagation is observable at fine scales using dense seismic networks. Fiber-optic sensing allows for long-term deployments of ultradense arrays that enable high-resolution measurements of infrequent, large earthquakes. We recorded the...

A simple predictive model for salt marsh internal deterioration under sea-level rise and sediment deficits: Application to Chesapeake Bay
Neil K. Ganju, Kate Ackerman, Zafer Defne, Giulio Mariotti, David Curson, Zachary Posnik, Joel Carr, Joanna Grand
2025, Estuaries and Coasts (48)
Salt marshes are dynamic biogeomorphic systems reliant on autochthonous and allochthonous input to maintain their three-dimensional configuration. Sea-level rise, subsidence, and sediment deficits can lead to submergence, open-water expansion, and ultimately loss of the vegetated marsh plain and associated ecosystem services. Widely used management-focused models focus on vegetation zonation in...

2025, Frontiers in Marine Science (12)
Coral reefs play vital roles in global marine systems and are currently facing increased threats of bleaching. Coral bleaching is heavily influenced by the host-associated microeukaryote community – most notably the dinoflagellate family Symbiodiniaceae. The apicomplexan family Corallicolidae, is the second most abundant member of the microeukaryote community, yet their...

Efforts to establish clear priorities can be hindered by information gaps, especially those related to the uncertainty associated with changing conditions that influence brown pelican populations. We addressed...
Evidence for offset of Cretaceous plutons by the Tintina fault in eastern Alaska: Implications for regional metallogeny
Douglas C. Kreiner, Erin Todd, James V. Jones III, Christopher S. Holm-Denoma, Laura Pianowski, Paul O’Sullivan
2025, Conference Paper
Cretaceous magmatism in eastern interior Alaska is voluminous, but temporally and spatially diverse – suggestive of varying sources and drivers. More than 150 new U-Pb zircon and more than 500 geochemical analyses of Cretaceous plutonic units allow for the grouping of distinct plutonic suites. Magmatism was continuous from 120-66 Ma...

Eve Bohnett, Jessica Schulz, Robert C. Dobbs, Thomas Hoctor, Bilal Ahmad, Wajid Rashid, J. Hardin Waddle
2025, Land (14)
Determining appropriate spatio-temporal scales for monitoring migratory shorebirds is challenging. Effective surveys must detect population trends without excessive or insufficient sampling, yet many programs lack formal evaluations of survey effectiveness. Using data from 2012 to 2019 on Louisiana’s barrier islands (Whiskey, west Raccoon, east Raccoon, and Trinity), we assessed how...
Catchment prioritization for freshwater mussel conservation in the Northeastern United States based on distribution modelling
Rebecca S.M. O’Brien, Graziella Vittoria DiRenzo, Allison H. Roy, Jason Carmignani, Rebecca M. Quinones, Jennifer B. Rogers, Beth I. Swartz
2025, PLoS ONE (20)
Freshwater mussels are critical to the health of freshwater systems, but their populations are declining dramatically throughout the world. The limited resources available for freshwater mussel conservation necessitates the geographic prioritization of conservation-related actions. However, lack of knowledge about freshwater mussel spatial distributions hinders decision making in this context. In...
