Terrence A. McCloskey, Christopher G. Smith, Kam-Biu Liu, Paul R. Nelson
2018, Frontiers in Ecology and Evolution (6)
Shoreline retreat is a tremendously important issue along the coast of the northern Gulf of Mexico, especially in Louisiana. Although this marine transgression results from a variety of causes, the crucial factor is the difference between marsh surface elevation and rising sea levels. In most cases, the primary cause of...
Energy-rich mesopelagic fishes revealed as a critical prey resource for a deep-diving predator using quantitative fatty acid signature analysis
Chandra Goetsch, Melinda G. Conners, Suzanne M. Budge, Yoko Mitani, William A Walker, Jeffrey F. Bromaghin, Samantha E. Simmons, Colleen Reichmuth, Daniel P. Costa
2018, Frontiers in Marine Science (5) 1-19
Understanding the diet of deep-diving predators can provide essential insight to the trophic structure of the mesopelagic ecosystem. Comprehensive population-level diet estimates are exceptionally difficult to obtain for elusive marine predators due to the logistical challenges involved in observing their feeding behavior and collecting samples for traditional stomach content or...

The influence of seep habitats on sediment macrofaunal biodiversity and functional traits
Amanda W. J. Demopoulos, Jill R. Bourque, Alanna Durkin, Erik E. Cordes
2018, Deep-Sea Research Part I: Oceanographic Research Papers (142) 77-93
Chemosynthetic ecosystems in the Gulf of Mexico (GOM) support dense communities of seep megafaunal invertebrates that rely on endosymbiotic bacteria for nutrition. Distinct infaunal communities are associated with the biogenic habitats created by seep biota, where habitat heterogeneity and sediment geochemistry influence local macrofaunal community structure. Here we examine the community structure and function of seep...

Shared habitat use by juveniles of three sea turtle species
Margaret M. Lamont, Autumn R. Iverson
2018, Marine Ecology Progress Series (606) 187-200
The first step in understanding how sympatric species share habitat is defining spatial boundaries. While home range data for juvenile sea turtles exists, few studies have examined spatial overlap of multiple species in foraging habitat. Using satellite tracking technology, we define home ranges for juveniles of 3 sea turtle species...
Two-event lode-ore deposition at Butte, USA: 40Ar/39Ar and U-Pb documentation of Ag-Au-polymetallic lodes overprinted by younger stockwork Cu-Mo ores and penecontemporaneous Cu lodes
Karen Lund, Ryan J. McAleer, John N. Aleinikoff, Michael A. Cosca, Michael J. Kunk
2018, Ore Geology Reviews (102) 666-700
The ore-genesis model for world-class deposits of the Butte mining district, Montana, USA, is deep pre-Main Stage porphyry Cu-Mo and overlying Main Stage Ag-Zn-Cu zoned-lode deposits, both of which formed from hydrothermal fluids driven by minor volumes of rhyolitic magma. The lode-specific model is that hydrothermal processes diminished in...
Multi-scale effects of land cover and urbanization on the habitat suitability of an endangered toad
Michael L. Treglia, Adam C Landon, Robert N. Fisher, Gerard Kyle, Lee A. Fitzgerald
2018, Biological Conservation (228) 310-318
Habitat degradation, entwined with land cover change, is a major driver of biodiversity loss. Effects of land cover change on species can be direct (when habitat is converted to alternative land cover types) or indirect (when land outside of the species habitat is altered). Hydrologic and ecological connections between terrestrial and aquatic...

Integrated population modeling provides the first empirical estimates of vital rates and abundance for polar bears in the Chukchi Sea
Eric V. Regehr, Nathan J. Hostetter, Ryan H. Wilson, Karyn D. Rode, Michelle St. Martin, Sarah J. Converse
2018, Scientific Reports (8)
Large carnivores are imperiled globally, and characteristics making them vulnerable to extinction (e.g., low densities and expansive ranges) also make it difficult to estimate demographic parameters needed for management. Here we develop an integrated population model to analyze capture-recapture, radiotelemetry, and count data for the Chukchi Sea subpopulation of polar...
