Re-examining the growing degree day minimum for grass carp spawning initiation in Lake Erie: Have we missed the mark? Re-examining the growing degree day minimum for grass carp spawning initiation in Lake Erie: Have we missed the mark?
Understanding the timing of life history processes of invasive fish species, such as adult aggregations during spawning, allows natural resource managers to optimize targeted population control efforts. Temperature-based estimates of the timing of spawning initiation for grass carp (Ctenopharyngodon idella) exist from its native range, but have not previously been developed for grass...

Repeated coral bleaching events have eroded reef accretion potential in the Florida Keys Repeated coral bleaching events have eroded reef accretion potential in the Florida Keys
Coral bleaching is now the primary driver of coral-reef degradation globally, threatening the persistence of coral-reef functions and the invaluable ecosystem services they support. The Florida Keys have been impacted by four severe, regional-scale coral-bleaching events, which occurred in 1997–1998, 2005, 2014–2015, and 2023. Our aim in this study was to quantify the effects of those...

Identifying overlap between native fish movements and a possible seasonal Grass Carp deterrent in the Sandusky River, Ohio, USA Identifying overlap between native fish movements and a possible seasonal Grass Carp deterrent in the Sandusky River, Ohio, USA
Riverine fishes are vulnerable to habitat fragmentation caused by interrupted access to vital habitats. Fragmentation using artificial structures can be used to limit the spread of invasive fishes by inhibiting movement between critical habitats. Thus, tradeoffs exist between maintaining connectivity for native species and restricting movement of invasive fishes. A nonphysical deterrent...

CRESCENT earthquake dynamic rupture, earthquake cycle, and tsunami code verification platform CRESCENT earthquake dynamic rupture, earthquake cycle, and tsunami code verification platform
Physics-based simulations are critical for understanding natural hazards. The increasing complexity of numerical codes requires benchmark exercises to verify that different computational methods yield consistent results when solving the same governing equations. Here, we present an open-access web platform designed for the verification of earthquake dynamic rupture, seismic cycle, and...

Spatially realistic dynamic N-mixture models Spatially realistic dynamic N-mixture models
Dispersal is a complex ecological process that can be driven by the abiotic environment, density-dependent processes and species mobility. Traditionally, dispersal has been studied with capture-based data that are often limited in space and time. More recently, spatial dynamic N-mixture models (i.e. N-mixture models accounting for dispersal among local populations and changes in...

Age reassignment using luminescence dating for the Mammoth Site, Black Hills, South Dakota, USA Age reassignment using luminescence dating for the Mammoth Site, Black Hills, South Dakota, USA
The Mammoth Site (MS) at Hot Springs, South Dakota, provides a unique opportunity to reconstruct paleoenvironmental conditions on the Northern Great Plains of the United States. Previous radiocarbon analyses of mammoth bone apatite suggested the MS sinkhole was deposited ∼42–23 cal ka BP. However, two U-series ages and one thermoluminescence (TL) age ranged between 150 and 101 ka...

Multivariate spatio-temporal clustering of wind–wave variability across European seas Multivariate spatio-temporal clustering of wind–wave variability across European seas
This study presents a multivariate spatio-temporal clustering framework to characterise joint wind–wave regimes across European seas using the fifth-generation atmospheric reanalysis produced by the European Centre for Medium-Range Weather Forecasts (ERA5; 1979–2014). Seasonal and annual statistics of significant wave height, mean wave period, wind speed, and wave/wind direction were...

Exploring the use of amino acid stable hydrogen isotope (δ2H) analysis to improve geographic assignment of wildlife Exploring the use of amino acid stable hydrogen isotope (δ2H) analysis to improve geographic assignment of wildlife
Stable isotopes of hydrogen (δ2H) have long been used to trace the movement and geographic origins of wildlife. δ2H analysis of individual amino acids (AA) offer a multivariate alternative to bulk tissue analysis, but the geographic resolving power of this approach remains underexplored. Here, we analyzed AA δ2H, along with bulk tissue δ2H, δ13C, and δ15N values of 32 feathers collected...

Estimating the importance of floating surface material to the total phosphorus transport in Silver Creek, Wisconsin using Particle Image Velocimetry Estimating the importance of floating surface material to the total phosphorus transport in Silver Creek, Wisconsin using Particle Image Velocimetry
Various techniques are used to estimate nutrient delivery in streams that combine flow and water-quality data. However, the transport of surface floating material is difficult to measure, and is therefore typically neglected when stream sampling and in the estimated nutrient delivery. Here, we describe an approach to estimate the amount of material (duckweed (Lemna genus), filamentous...

Successes and opportunities for solutions-oriented conservation research: Lessons learned from avian science Successes and opportunities for solutions-oriented conservation research: Lessons learned from avian science
Conservation science struggles with an ongoing divide between research and action. Given its history of broad public engagement and multi-scale management coordination, avian conservation typifies many of the challenges, successes, and opportunities across the broader field of conservation and is rich with examples that may guide solutions-oriented conservation science. In semi...

Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars
Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase-rich light-toned float rocks. SuperCam identified the distinctive signature of corundum (α-Al2O3) in these...
