High Site Fidelity and Elevated δ¹⁵N in Bonefish (Albula vulpes) Suggest Localized Wastewater Stress in a Marine National ParkNARA Subscribed
Coastal zones are subjected to many anthropogenic stresses that operate on multiple spatial scales. Understanding how these stressors interact with the movement and resource ecology of mobile species is critical for effective conservation and management. Biscayne National Park (BNP) is adjacent to Miami (U.S.) and supports an economically important recreational fishery for bonefish ( Albula vulpes ). Within BNP, the western re...
Sustaining scenarios: researcher-practitioner reflections on extending research beyond project boundariesNARA Subscribed
We evaluate the results of a food system scenarios workshop in Flint, Michigan designed to co-create actionable pathways toward desirable futures in the medium-term (20 years), alongside analysis from practitioners one year post workshop. The goal of the scenario planning process is to support the translation and usability of research findings beyond project boundaries through the engagement of diverse voices and perspectives,...
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...
Drained Agricultural Peatlands as Persistent Carbon Sources: Implications for Carbon and Water Use Intensity in Food ProductionNARA Subscribed
Peatlands have the capacity to sequester large quantities of carbon and can therefore play an important role in climate change mitigation. However, anthropogenic activities alter their hydrological regimes, converting them from net CO 2 sinks into net sources. In England and elsewhere, lowland peatlands have been heavily drained and modified for agricultural land use, resulting in some of the most productive farmland in the UK...
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...
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...
Extreme Drought Increases the Temporal Variability of Grassland Productivity by Suppressing Dominant GrassesNARA Subscribed
Extreme droughts are intensifying, yet their impact on temporal variability of grassland functioning and its drivers remains poorly understood. We imposed a 6‐year extreme drought in two semiarid grasslands to explore how drought influences the temporal variability of ANPP and identify potential stabilising mechanisms. Drought decreased ANPP while increasing its temporal variability across grasslands. In the absence of drought...
Given the United Nations’ ambitious goal—endorsed by more than 100 nations, including Canada—of protecting 30% of the world’s marine ecosystems by 2030 (UN, 2023), the need to establish, expand, and track the effectiveness of protected areas is becoming more pressing each year. Effective planning for and monitoring of marine protected areas (MPAs) rely on the availability of quality baseline ecological and oceanographic inform...
Trophic niche of a nonnative invader and environmental drivers of its increasing populations in the coastal EvergladesNARA Subscribed
The Florida Everglades is a critically important, but highly threatened ecosystem that is becoming increasingly susceptible to the invasion of non-native species. This study investigated the ecological role of the invasive peacock eel ( Macrognathus siamensis ) within this ecosystem using 15 years of electrofishing data and stable isotope analysis. We investigated the population trends of peacock eels at the marsh-mangrove eco...
New directions for Indigenous and local knowledge research and application in fisheries science: Lessons from a systematic reviewNARA Subscribed
Social‐ecological systems like fisheries provide food, livelihoods and recreation. However, lack of data and its integration into governance hinders their conservation and management. Stakeholders possess site‐specific knowledge crucial for confronting these challenges. There is increasing recognition that Indigenous and local knowledge (ILK) is valuable, but structural differences between ILK and quantitative archetypes have...
The aluminous calcium-ferrite type phase (CF) and new aluminous phase (NAL) are thought to hold the excess alumina produced by the decomposition of garnet in MORB compositions in the lower mantle. The respective stabilities of CF and NAL in the nepheline-spinel binary (NaAlSiO $$_{4}$$ 4 –MgAl $$_{2}$$ 2 O $$_{4}$$ 4 ) are well established. However with the addition of further components the phase relations at lower mantle con...
