Assessing fish growth changes under an ecosystem regime shift: The approach of linear mixed-effects modeling with application to Lake Huron lake trout Assessing fish growth changes under an ecosystem regime shift: The approach of linear mixed-effects modeling with application to Lake Huron lake trout
Linear mixed-effects modeling has been used to characterize fish growth changes over time, but early studies did not fully consider the implicit relationship among the three major factors of fish age, year-class, and sampling year in model development. Our objective is to resolve this issue and develop a linear mixed-effects model to clearly assess how lake trout (Salvelinus namaycush)...

The rise of U.S. photovoltaics: An exploration of land use density trends in large-scale solar facility attributes, 2012-2021 The rise of U.S. photovoltaics: An exploration of land use density trends in large-scale solar facility attributes, 2012-2021
An energy transition is underway in the United States; renewable energy generation is now on par with coal and nuclear generation. The number of large-scale solar photovoltaic facilities increased approximately tenfold between 2012 and 2021, with an associated 25-fold increase in cumulative installed capacity. With ambitious decarbonization and renewable energy deployment goals at both...

Drowned river mouth lakes are winter foraging habitats for the expanding Lake Michigan cisco Coregonus artedi population Drowned river mouth lakes are winter foraging habitats for the expanding Lake Michigan cisco Coregonus artedi population
Characterizing fish movements is required for understanding habitat use, energy flow, and trophic structure and can inform fisheries management. Drowned river mouth (DRM) lakes are productive inland habitats in the Laurentian Great Lakes basin used by migratory fishes. Despite recognition of their ecological connections to the Great Lakes, the value of DRM lakes as seasonal habitats is...

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species Success of restoration strategies in preventing extirpation of 2 critically endangered coral species
An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected. These species have been the primary focus of reef restoration in Florida for decades. Substantial losses of these species...

Assessment of undiscovered oil and gas resources in the Santa Maria Basin Province, California, 2024 Assessment of undiscovered oil and gas resources in the Santa Maria Basin Province, California, 2024
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean conventional resources of 67 million barrels of oil and 56 billion cubic feet of gas in the Santa Maria Basin Province of California.

Divergent responses of seed banks and aboveground vegetation to drought and deluge in grasslands across an elevational gradient Divergent responses of seed banks and aboveground vegetation to drought and deluge in grasslands across an elevational gradient
Increased variability in precipitation associated with climate change creates extreme conditions of drought and deluge that can have profound effects on the abundance and composition of plant communities. Responses to these extremes likely vary across climatic gradients and depend on local plant community composition, which includes the emergent, aboveground vegetation as well as...

Land cover, elevation, and precipitation predict distribution and hotspots of three bird species of concern in boreal Alaska Land cover, elevation, and precipitation predict distribution and hotspots of three bird species of concern in boreal Alaska
The boreal forest biome is an important breeding area for migratory birds and is undergoing rapid changes, including drying of wetlands, changes to vegetation composition, and human development. Many boreal bird populations are declining, but information is often lacking on how these species associate with habitat characteristics and thus how they may respond to changing conditions. We...

Long‐period ground motions from dynamic rupture simulations of large earthquakes on the creeping Hayward–Calaveras–Rodgers Creek fault system Long‐period ground motions from dynamic rupture simulations of large earthquakes on the creeping Hayward–Calaveras–Rodgers Creek fault system
he Hayward, Calaveras, and Rodgers Creek faults in the San Francisco Bay region of California have a high probability of producing a large earthquake in the next decades. Although these faults creep, the creep is insufficient to keep up with their relatively rapid slip rates on their deepest sections, so they have been storing tectonic strain since their last large earthquakes, with the...

Observations of tear-drinking by lepidopterans on moose (Alces alces americana) in northeastern North America Observations of tear-drinking by lepidopterans on moose (Alces alces americana) in northeastern North America
Lepidoptera have long been known to feed on the tears of vertebrates as a presumed source of minerals or nutrients. While this unusual behavior has been observed in a variety of species, only a single previous record has been documented outside of the tropics. Here, we present the first documentation of moths visiting the eyes of a bull moose (Alces americanus americanus), captured via...

Modeling the influence of upper and lower shoreface dynamics on barrier island evolution Modeling the influence of upper and lower shoreface dynamics on barrier island evolution
Barrier island resilience to climate impacts depends on sediment redistribution between the subaqueous shoreface and subaerial barrier during sea-level rise and storms. However, autogenic interactions between the upper and lower shoreface and their influence on the subaerial barrier are poorly characterized. Here, we explore the influences of various shoreface components on barrier...

Rare earth elements on the Moon Rare earth elements on the Moon
Rare earth elements (REEs) are a scarce but vital resource for our modern economies and lifestyles. Since the late 1990s, China has supplied the vast majority of the world’s refined REEs. Increasing global demand has broadened the search for REE deposits to unconventional places, including the Moon. Although most lunar rocks have very low REE concentrations, Apollo samples showed that...
