Quantifying intraspecific variation in host resistance ad tolerance to a lethal pathogen Quantifying intraspecific variation in host resistance ad tolerance to a lethal pathogen
Testing for intraspecific variation for host tolerance or resistance in wild populations is important for informing conservation decisions about captive breeding, translocation, and disease treatment. Here, we test the importance of tolerance and resistance in multiple populations of boreal toads (Anaxyrus boreas boreas) against Batrachochytrium dendrobatidis (Bd), the amphibian fungal...

Why do avian responses to change in Arctic green-up vary? Why do avian responses to change in Arctic green-up vary?
Global climate change has altered the timing of seasonal events (i.e., phenology) for a diverse range of biota. Within and among species, however, the degree to which alterations in phenology match climate variability differ substantially. To better understand factors driving these differences, we evaluated variation in timing of nesting of eight Arctic-breeding shorebird species at 18...

Pockmarks offshore Big Sur, California provide evidence for recurrent, regional, and unconfined sediment gravity flows Pockmarks offshore Big Sur, California provide evidence for recurrent, regional, and unconfined sediment gravity flows
Recent surface ship multibeam surveys of the Sur Pockmark Field, offshore Central California, reveal >5,000 pockmarks in an area that is slated to host a wind farm, between 500- and 1,500-m water depth. Extensive fieldwork was conducted to characterize the seafloor environment and its recent geologic history, including visual observations with remotely operated vehicles, sediment core...

Chronic wasting disease alters the movement behavior and habitat use of mule deer during clinical stages of infection Chronic wasting disease alters the movement behavior and habitat use of mule deer during clinical stages of infection
Integrating host movement and pathogen data is a central issue in wildlife disease ecology that will allow for a better understanding of disease transmission. We examined how adult female mule deer (Odocoileus hemionus) responded behaviorally to infection with chronic wasting disease (CWD). We compared movement and habitat use of CWD-infected deer (n = 18) to those that succumbed to...

Development and validation of a GT-seq panel for genetic monitoring in a threatened species using minimally invasive sampling Development and validation of a GT-seq panel for genetic monitoring in a threatened species using minimally invasive sampling
Minimally invasive samples are often the best option for collecting genetic material from species of conservation concern, but they perform poorly in many genomic sequencing methods due to their tendency to yield low DNA quality and quantity. Genotyping-in-thousands by sequencing (GT-seq) is a powerful amplicon sequencing method that can genotype large numbers of variable-quality samples...

Repeated coseismic uplift of coastal lagoons above the Patton Bay Splay Fault System, Montague Island, Alaska, USA Repeated coseismic uplift of coastal lagoons above the Patton Bay Splay Fault System, Montague Island, Alaska, USA
Coseismic slip on the Patton Bay splay fault system during the 1964 Mw 9.2 Great Alaska Earthquake contributed to local tsunami generation and vertically uplifted shorelines as much as 11 m on Montague Island in Prince William Sound (PWS). Sudden uplift of 3.7–4.3 m caused coastal lagoons along the island's northwestern coast to gradually drain. The resulting change in depositional...

Assessing wild turkey productivity before and after a 14-day delay in the start date of the spring hunting season in Tennessee Assessing wild turkey productivity before and after a 14-day delay in the start date of the spring hunting season in Tennessee
Ten state wildlife management agencies in the United States, including six within the Southeast, have delayed their spring wild turkey (Meleagris gallopavo) hunting seasons since 2017 by five or more days to address concerns related to the potential effects of hunting on wild turkey seasonal productivity. One hypothesis posits that if the spring hunting season is too early, there may be

Static and dynamic strain in the 1886 Charleston, South Carolina, earthquake Static and dynamic strain in the 1886 Charleston, South Carolina, earthquake
During the 1886 Mw 7.3 Charleston, South Carolina, earthquake, three railroads emanating from the city were exposed to severe shaking. Expansion joints in segmented railroad tracks are designed to allow railroad infrastructure to withstand a few parts in 10,000 of thermoelastic strain. We show that, in 1886, transient contractions exceeding this limiting value buckled rails, and...

Resilience is not enough: Toward a more meaningful rangeland adaptation science Resilience is not enough: Toward a more meaningful rangeland adaptation science
Rangeland ecosystems, and their managers, face the growing urgency of climate change impacts. Researchers are therefore seeking integrative social-ecological frameworks that can enhance adaptation by managers to these climate change dynamics through tighter linkages among multiple scientific disciplines and manager contexts. Social-ecological framings, including resilience and...

Large-scale assessment of genetic structure to assess risk of populations of a large herbivore to disease Large-scale assessment of genetic structure to assess risk of populations of a large herbivore to disease
Chronic wasting disease (CWD) can spread among cervids by direct and indirect transmission, the former being more likely in emerging areas. Identifying subpopulations allows the delineation of focal areas to target for intervention. We aimed to assess the population structure of white-tailed deer (Odocoileus virginianus) in the northeastern United States at a regional scale to inform...

Updated range map of an endangered salamander and congeneric competitor reveals different niche preferences Updated range map of an endangered salamander and congeneric competitor reveals different niche preferences
Estimating distributions for cryptic and highly range-restricted species induces unique challenges for species distribution modeling. In particular, bioclimatic covariates that are typically used to model species ranges at regional and continental scales may not show strong variation at scales of 100s and 10s of meters. This limits both the likelihood and usefulness of correlated...

Accuracy, accessibility, and institutional capacity shape the utility of habitat models for managing and conserving rare plants on western public lands Accuracy, accessibility, and institutional capacity shape the utility of habitat models for managing and conserving rare plants on western public lands
Public lands are often managed for multiple uses ranging from energy development to rare plant conservation. Habitat models can help land managers assess and mitigate potential effects of projects on rare plants, but it is unclear how models are currently being used. Our goal was to better understand how staff in the Bureau of Land Management currently use habitat models to inform their...
