The host’s ability to clear parasites (resistance) and their capacity to reduce the impact of a given parasite burden (tolerance) is often described under conditions of a single pathogen challenge. We developed a mouse infection model to investigate the impact of co-infection on host resistance and tolerance to Heligmosomoides bakeri . C57BL/6 mice were infected with the helminth parasite H. bakeri and Theiler’s murine encepha...
Enhancing farmers’ access to neglected crop seeds for healthy diets in a changing climate: six recommendations for policy actionNARA Subscribed
Food insecurity and poor diets undermine human health, livelihoods, and aspirations. Climate change further exacerbates the problem of achieving zero hunger. Promoting the production of a diverse portfolio of nutrient-dense, climate-resilient crops enables food supply for healthy diets in the coming years and decades. Many are underutilized even though they are considered opportunity crops, with an unrealized potential to impr...
Impacts of sea level rise on the world’s shorebirdsNARA Subscribed
Sea level rise (SLR) poses a significant threat to coastal ecosystems worldwide. Migratory shorebirds rely heavily on nearshore and intertidal ecosystems throughout the annual cycle and are currently undergoing global declines due to the loss of coastal habitat, suggesting that these species may be highly susceptible to future SLR. However, the effects of SLR on shorebird habitat—and, by extension, populations—remain poorly un...
Dune Russet (COTX08063-2Ru) is the first French fry russet potato cultivar released by the Texas A&M Potato Breeding Program. It derives from a cross made by the Colorado State University Potato Program between Premier Russet and A99073-1 and was subsequently selected and advanced by the Texas Program. Dune Russet has oblong potato tubers with light russet skin texture and white flesh. It is characterized by having excellent F...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Assessing Climate Adaptation Among Canada Lynx ( Lynx canadensis ) Populations at the Trailing EdgeNARA Subscribed
Species must acclimate, shift their distribution, or adapt in place in response to anthropogenic climate change. Populations at the low‐latitude trailing edge of the species distribution typically experience thermal conditions closest to the upper limit of their thermoregulatory capacity. Landscape and functional genomic approaches provide quantitative measures of risk and adaptive capacity which can inform and prioritise cons...
Sporecasting Biogeography Across Scales: Continental Patterns and Local Constraints on Macrofungal DispersalNARA Subscribed
Understanding how aerial fungal diversity varies across space, habitat, and disturbance is key to linking local‐scale sporocarp (fruiting body) reproduction with continental‐scale biogeography. In this study, we combined passive spore trap metabarcoding with macrofungal sporocarp records from 31 plots in eight sites across North America to quantify how site, habitat, and fire history shape aerial macrofungal communities. From...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Basin-wide disruption of ecological strategies of woody species induced by a dam breach in BrazilNARA Subscribed
The Samarco dam breach in Brazil drastically altered soil and water conditions along the Rio Doce, severely impacting riparian vegetation. This study assessed how these environmental changes influenced the functional traits and ecological strategies (CSR scheme) of adult and juvenile woody plants in reference (unaffected) and impacted sites affected by mine tailings deposition. We hypothesized that mining tailings would reduce...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Environmental Variability Shapes Life‐History Trade‐Offs Within and Between Populations of a Long‐Lived SeabirdNARA Subscribed
Individuals face a trade‐off between allocating resources to reproduction or self‐maintenance, yet the drivers of the existence and strength of such trade‐off have been hard to determine. Environmental conditions are thought to play a crucial role, as long‐lived species are predicted to favour more precautionary life‐history strategies in variable environments. However, empirical evidence remains limited. Using long‐term monit...
