Scott Jennings, Katie M. Dugger, Grant Ballard, David Ainley
2023, Ornithology (140)
We conducted the first assessment of Adélie Penguin (Pygoscelis adeliae) chick survival that accounts for imperfect resighting. We found that when chicks are larger in size when they enter the crèche stage (the period when both parents forage at the same time and chicks are left relatively unprotected), they...
Fire modifies plant–soil feedbacks
Christopher Warneke, Stephanie G. Yelenik, Lars Brudvig
2023, Ecology (104)
Although plant–soil feedbacks (interactions between plants and soils, often mediated by soil microbes, abbreviated as PSFs) are widely known to influence patterns of plant diversity at local and landscape scales, these interactions are rarely examined in the context of important environmental factors. Resolving the...

Tanner L. Carlson, Lindsey A. P. LaBrie, Jeff S. Wesner, Steven R. Chipps, Alison A. Coulter, Benjamin J. Schall
2023, Animal Biotelemetry (11)
One of the most important considerations for acoustic telemetry study designs is detection probability between the transmitter and the receiver. Variation in environmental (i.e., wind and flow) and abiotic (i.e., bathymetry) conditions among aquatic systems can lead to differences in detection probability temporally or between systems. In this study we...

2023, Geochimica et Cosmochimica Acta (343) 180-195
The oxidative weathering of sulfidic rock can profoundly impact watersheds through the resulting export of acidity and metals. Weathering leaves a record of mineral transformation, particularly involving minor redox-sensitive phases, that can inform the development of conceptual and quantitative models. In sulfidic sedimentary rocks, however, variations in depositional history, diagenesis and mineralization can...
