Rationale Following the discontinuation of long access (LgA) to cocaine self-administration rats show a time-dependent increase in motivation for drug (“incubation of craving”) thought to be mediated by enhancements in transmission via nucleus accumbens (NAc) calcium-permeable AMPA receptors (CP-AMPARs). Intermittent access (IntA) to cocaine produces even more robust addiction-like behavior than LgA, but it is not known if thi...
Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs WorldwideNARA Subscribed
Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
Coastal Dune Assessment Tool: developing an index to support ecological evaluation and management decisions along the Irish coastlineNARA Subscribed
Coastal dune environments are vulnerable systems threatened by a complex network of physical, biotic and anthropic pressures. Even though they host high biodiversity, dune habitats are deteriorating and disappearing, causing the loss of their protective role against climate hazards. Finding a repeatable methodology to assess the ecological condition of these ecosystems is important to support decision-making and preserve dune...
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...
Multiple Community Properties Drive Ecosystem Resistance and Resilience to Extreme Climate Events Across Mesic GrasslandsNARA Subscribed
Ecosystem resistance and resilience to extreme climate events is impacted by community properties, including biodiversity. However, the relative importance of species richness, evenness and dominance is debated and is further modulated by global change factors such as nutrient addition. Using nearly 40 years of data from naturally‐assembled plant communities at three Long‐Term Ecological Research sites, we found that while spe...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
New Approach Needed To Address Declining Forestry Research Capacity And Relevancy in the US: A Call-To-ActionNARA Subscribed
Recent dramatic reductions in research funding and personnel for university and government organizations by the new federal administration will reduce forestry research capacity in the coming years. However, these cuts only highlight the long-standing decline in forestry research capacity that has been occurring over the past several decades. These reductions will continue to impair the country’s ability to meet the scale and...
Genetic diversity and historical demography of the imperiled rattlesnake-master borer moth (Papaipema eryngii)NARA Subscribed
Large-scale habitat loss and degradation have triggered a global biodiversity crisis with ecological-specialist species at increased risk of extinction. The Rattlesnake-Master Borer ( Papaipema eryngii ) is a small noctuid moth whose larvae feed exclusively on rattlesnake master ( Eryngium yuccifolium ), a native grassland plant ranging throughout the eastern United States. Widespread loss of grassland habitats has resulted in...

Predicting the progression of MCI and Alzheimer’s disease on structural brain integrity and other features with machine learningNARA Subscribed
Machine learning (ML) on structural MRI data shows high potential for classifying Alzheimer’s disease (AD) progression, but the specific contribution of brain regions, demographics, and proteinopathy remains unclear. Using Alzheimer’s Disease Neuroimaging Initiative (ADNI) data, we applied an extreme gradient-boosting algorithm and SHAP (SHapley Additive exPlanations) values to classify cognitively normal (CN) older adults, th...
A global assessment of the status of tertiary, vocational, and technical forest education and training found deficits in inclusion of knowledge and student diversity. Coverage of forest services and cultural and social issues was characterized as weak in the curricula of many programs. The inclusion of traditional and Indigenous knowledge was frequently poor or absent. Gaps were found in enrollment at tertiary education levels...
