Vascular contribution to cognitive impairment and dementia (VCID): proceedings of 2025 workshop of the Jackson LaboratoryNARA Subscribed
The first Vascular Contributions to Cognitive Impairment and Dementia (VCID) Workshop, held on May12-16, 2025 at The Jackson Laboratory, provided scientific content and career development training in the latest developments in VCID and Alzheimer’s Disease (AD) and related dementia (ADRD). The Workshop aimed to foster interdisciplinary collaborations and empower the next generation of diverse scientists to advance ADRD research...
Deviations from additivity in APOE4-mediated late-onset Alzheimer’s disease risk across races and ethnicitiesNARA Subscribed
APOE ’s ε4 haplotype ( APOE4 ) is late onset Alzheimer’s disease’s (LOAD) strongest genetic risk factor. Therefore, accurately modeling APOE4 ’s effect is critical to understanding LOAD. This is especially important as APOE4 odds ratios (OR) vary across racial and ethnic (R/E) groups. We analyzed the APOE4 -LOAD association in 3,196 East Asian, 31,105 non-Hispanic White (White), 1,646 Hispanic and Latino (Hispanic), and 6,068...
Less cooperative belowground plant mutualists negatively affect aboveground herbivore growth and survivalNARA Subscribed
Resource mutualists like nitrogen (N)-fixing rhizobia can improve the quality of plants available to higher trophic levels, particularly primary consumers like insect herbivores. However, there is substantial variation in mutualist quality. How this variation in mutualist quality affects higher trophic levels, such as herbivores, is unclear, as high-quality resource mutualists could increase both leaf nutrient content, which s...
Periodical cicada ( Magicicada spp.) ranges have continued to decline even as their habitat has rebounded from historic lows. This counterintuitive trajectory may be a consequence of Magicicada 's limited dispersal capabilities combined with their requirement that individual host trees survive across decades. Indeed, we find that the presence of Magicicada breeding populations is best predicted by tree cover in 1930, not by pr...
Assessing shortnose sturgeon response to estuarine dredging in the Savannah River using a before-after control-impact (BACI) approachNARA Subscribed
Estuaries are productive ecosystems that support diverse aquatic species and human economies through fisheries, recreation, and navigation. However, coastal development and dredging have altered the ecological processes of estuarine habitats. In the Savannah River estuary, the Savannah Harbor Expansion Project (SHEP) deepened the river’s navigational channel by dredging to amplify vessel commerce. The endangered shortnose stur...
Divergence in migratory behaviour represents a striking and common axis of life‐history variation in animals. Plastic changes in adult animals in preparation for migration are well known, but the differences in early development between migratory and non‐migratory forms are not well documented. These differences might contribute to reproductive isolation because of the potentially substantial divergence in metabolism and physi...
