Robert S. Cornman
2024, PeerJ (12)
BackgroundPrevious work found that numerous genes positively selected within the hoary bat (Lasiurus cinereus) lineage are physically clustered in regions of conserved synteny. Here I further validate and expand on those finding utilizing an updated L. cinereus genome assembly and additional bat species as well as other tetrapod outgroups.MethodsA chromosome-level...
Towards entity-aware conditional variational inference for heterogeneous time-series prediction: An application to hydrology
Rahul Ghosh, Wallace Mcaliley, Arvind Renganathan, Michael Steinbach, Christopher Duffy, Vipin Kumar
2024, Conference Paper, Proceedings of the 2024 SIAM International Conference on Data Mining (SDM)
Many environmental systems (e.g., hydrology basins) can be modeled as entity whose response (e.g., streamflow) depends on drivers (e.g., weather) conditioned on their characteristics (e.g., soil properties). We introduce Entity-aware Conditional Variational Inference (EA-CVI), a novel probabilistic inverse modeling approach, to deduce entity characteristics from observed driver-response...
Deep vs shallow: GPS tags reveal a dichotomy in movement patterns of loggerhead turtles foraging in a coastal bay
Margaret Lamont, Daniel Slone, James P. Reid, Susan M. Butler, Joseph A. Alday
2024, Movement Ecology (12)
BackgroundIndividual variation in movement strategies of foraging loggerhead turtles have been documented on the scale of tens to hundreds of kilometers within single ocean basins. Use of different strategies among individuals may reflect variations in resources, predation pressure or competition. It is less common for individual turtles to...
Characterizing sulfur redox state and geochemical implications in deep-time using mineral chemistry network analysis
Elisha Kelly Moore, Joseph Diedolf IV, Shaunna M. Morrison, Daniel Hummer
2024, Geochimica et Cosmochimica Acta (376) 25-36
Sulfur (S) is a central element in global biogeochemical cycling and Earth’s redox evolution. Minerals that contain S are an important record of local environmental conditions at the time of their formation based on chemical speciation and redox. However, the oxidation state of S for hundreds of different S-containing minerals...

Carl G. Lundblad, Christopher R. Anthony, Tyler Dungannon, Kimberly A. Haab, Elizabeth M. Schuyler, Chelsea E. Sink, Katie M. Dugger, Christian A. Hagen
2024, The Wildlife Society Bulletin (48)
Wildlife tracking studies have become ubiquitous in ecology and now provide previously unobtainable data regarding individual movement, vital rates, and population demographics. However, tracking devices can potentially reduce survival of study subjects, generating biases in the vital rates they seek to measure. Previous studies have found that greater sage-grouse (Centrocercus...

Explosive 2018 eruptions at Kīlauea driven by a collapse-induced stomp-rocket mechanism
Joshua Allen Crozier, Josef Dufek, Leif Karlstrom, Kyle R. Anderson, Ryan Cain Cahalan, Weston Thelen, Mary Catherine Benage, Chao Liang
2024, Nature Geoscience (17) 572-578
Explosive volcanic eruptions produce hazardous atmospheric plumes composed of tephra particles, hot gas and entrained air. Such eruptions are generally driven by magmatic fragmentation or steam expansion. However, an eruption mechanism outside this phreatic–magmatic spectrum was suggested by a sequence of 12 explosive eruptions in May...
Comparing risk of chronic wasting disease occurrence using Bayesian hierarchical spatial models and different surveillance types
Kristin J. Bondo, Christopher S. Rosenberry, David Stainbrook, W. David Walter
2024, Ecological Modeling (493)
Spatial modeling of wildlife diseases can be used to describe patterns of disease risk, understand biological mechanisms of disease occurrence, and for spatial prediction. Risk of wildlife disease occurrence in relation to environmental variables is often modeled and predicted using Markov chain Monte Carlo (MCMC) methods, which are unsuitable for...

Behavioral trade-offs and multitasking by elk in relation to predation risk from Mexican gray wolves
Zachary J. Farley, Cara J. Thompson, Scott T. Boyle, Nicole M. Tatman, James W. Cain III
2024, Ecology and Evolution (14)
Predator non-consumptive effects (NCE) can alter prey foraging time and habitat use, potentially reducing fitness. Prey can mitigate NCEs by increasing vigilance, chewing-vigilance synchronization, and spatiotemporal avoidance of predators. We quantified the relationship between Mexican wolf (Canis lupus baileyi) predation risk and elk (Cervus...

2024, Landscape Ecology (39)
ContextDynamic feedbacks between physical structure and ecological function drive ecosystem productivity, resilience, and biodiversity maintenance. Detailed maps of canopy structure enable comprehensive evaluations of structure–function relationships. However, these relationships are scale-dependent, and identifying relevant spatial scales to link structure to function remains challenging.ObjectivesWe identified optimal scales...

2024, JGR Earth Surface (129)
The 26 January 1700 CE Cascadia subduction zone earthquake ruptured much of the plate boundary and generated a tsunami that deposited sand in coastal marshes from northern California to Vancouver Island. Although the depositional record of tsunami inundation is extensive in some of these marshes, few sites...

Margaret Hunter, Kristian Meissner, Catherine Abbott, Florien Leese, Gernot Segelbacher
2024, Report
The widespread adoption of environmental DNA (eDNA) detection tools for biodiversity monitoring has led to the need for universal data standards to inform principled eDNA data applications. Improvements in understanding the meaning and possible uncertainty of eDNA data can minimize erroneous conclusions, increase confidence in eDNA data, and maximize conservation...
Milkweed and floral resource availability for monarch butterflies (Danaus plexippus) in the United States
Laura Lukens, Jennifer Thieme, Wayne E. Thogmartin
2024, Frontiers in Ecology and Evolution (12)
The global decline of pollinators, particularly insects, underscores the importance of enhanced monitoring of their populations and habitats. However, monitoring some pollinator habitat is challenging due to widespread species distributions and shifts in habitat requirements through seasons and life stages. The monarch butterfly (Danaus plexippus), a migratory insect pollinator...
