Storying a responsive agroforestry technical assistance and training landscape in the USNARA Subscribed
In response to limited technical assistance capacity available to meet growing producer interest in agroforestry in the US, several inter-regional organizers of a burgeoning effort to coordinate national-scale agroforestry technical assistance and training (TAT) focused multiple sessions at the 2025 North American Agroforestry Conference on current conditions and surfacing opportunities for the development of agroforestry prof...
Standardized microhaplotype databases and frameworks for assessing and mining crop genetic diversityNARA Subscribed
Keymessage Standardized microhaplotype databases for eight diverse crops enable multiallelic analyses, comparative genetics, and breeding decisions. Abstract Microhaplotypes are short genomic segments that contain multiple tightly linked variants, providing multi-allelic data that can enhance genetic resolution compared to traditional biallelic single nucleotide polymorphism (SNP) markers. Here, we present the creation and uti...
The Kulanaokuaiki Tephra Unit 3 (900 C.E.) was a subplinian basaltic scoria eruption, the largest known to have occurred at Kīlauea’s summit. The initiation mechanism and cause(s) of this highly hazardous eruption remain poorly understood, particularly as this style of activity has not been observed in the modern period. We use olivine diffusion timescales from Fe-Mg and lithium zoning to assess magma storage timescales and ev...
Background and aims Biological nitrogen fixation (BNF) is central to long-term pedogenesis and overall terrestrial ecosystem development. Rates of asymbiotic BNF are potentially constrained by carbon (C), phosphorus (P), and/or nitrogenase cofactor elements (e.g., iron [Fe], vanadium [V], and molybdenum [Mo]), but our understanding of the biogeochemical trajectories of cofactor elements throughout pedogenesis is limited. Metho...
Purpose Carbohydrate availability is reduced during prolonged exercise, and this may contribute to the loss of power output at the intensity domain transitions. The aim of this study was to investigate the effects of lowered carbohydrate availability on power output at intensity domain transitions, muscle activation, and gross cycling efficiency in endurance-trained female cyclists. Methods Nine well-trained female cyclists co...
Butternut ( Juglans cinerea L.) is a rapidly declining tree species threatened by Ophiognomonia clavigignenti-juglandacearum (Oc-j), the causal agent of butternut canker. The introduction of Japanese walnut ( Juglans ailantifolia Carrière), which hybridizes with butternut and exhibits greater resistance to the disease, presents both a conservation challenge and a potential avenue for genetic improvement. Identifying non-admixe...
Extensive phospholipid resorption from senescing leaves is not associated with phospholipid substitution in an oligotrophic heathNARA Subscribed
Background and aims In leaves, ~ 25% of phosphorus (P) is allocated to membrane phospholipids. A significant amount of leaf P is resorbed during leaf senescence to reduce plant P loss upon leaf abscission and fuel the growth of new leaves. High P resorption observed in plants on P depleted soils has been associated with extensive resorption of all P-fractions, including phospholipids, from senescent leaves. This high resorptio...
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...
Mucilage addition increases aggregate stability and tolerance of microbes to soil dryingNARA Subscribed
Background and Aims Polysaccharide-rich mucilage from plant roots alters soil structure and microbial microhabitats, potentially modifying microbial responses to drying and rewetting. Here we tested the hypotheses that mucilage strengthens soil aggregates, increases microbial survival during dry–rewet cycles, and alters respiration responses to drying and rewetting. Methods To distinguish effects arising from the physical and...
Producing functional proteins involves multiple steps during mRNA translation on the ribosomes. However, co-translational regulatory mechanisms remain poorly characterized in intact mammalian systems. As a proof-of-concept, we developed a multi-omics approach to investigate endothelial-specific, co-translational regulation by modifying the translating ribosome affinity purification (TRAP) in vivo. We simultaneously co-immunopr...
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...
Planktonic response to pulse or continuous inorganic nutrient inputs: temporal variations and monitoring implicationsNARA Subscribed
Coastal lagoons are dynamic systems where the mode of nutrient input, continuous or pulsed, or a combination, can significantly affect plankton community structure and function. We conducted a spring field microcosm experiment in a Mediterranean lagoon to evaluate how three nutrient delivery regimes influence planktonic dynamics, using biomass measurements and extracellular enzyme activity (EEA) as functional indicators. Conti...
The crustal element cycle allows continuous redistribution of elements through different crustal reservoirs. Although retrogression after peak metamorphism is commonly known to affect both major and trace elements, particularly in the presence of fluids, much is still unknown about the trace element mass transfer associated with specific retrograde reactions. This study investigates the extent to which the retrograde breakdown...
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...
