Whole genome resequencing data provide high-resolution conservation insights into population structure and life historyNARA Subscribed
Whole genome resequencing can be a powerful tool for uncovering biological insights and quantifying population genomic metrics relevant to conservation. These insights have the potential to be most profound in secretive or elusive species that are understudied but whose populations may be waning. The western chicken turtle ( Deirochelys reticularia miaria ) is one such example where conservationists are concerned about reporte...
Metabolic Strategies Under Heat Stress in Non‐Adapted and High‐Temperature‐Adapted Lines of a Marine DiatomNARA Subscribed
In the last decade, numerous laboratory experiments have demonstrated that when marine phytoplankton are exposed to thermal stress, they can evolve high temperature tolerance in a short time (months). This evolutionary potential may ensure the persistence of marine phytoplankton species under current and future global warming. However, the effect of such adaptation on the phytoplankton's interaction with the environment and ot...
Revealing Coix lacryma-jobi var. lacryma-jobi (Job’s tears) in Han Dynasty burials with evidence from phytolith identificationNARA Subscribed
Coix lacryma-jobi L. (Job’s tears, adlay, yiyi 薏苡in Chinese) is a tropical member of the Poaceae family which is widely grown in southeast Asia for its grain, as medicine and for beads. However, archaeobotanical evidence of Coix from macrofossils or phytoliths remains limited, and the varieties used in ancient China have yet to be identified through research. In this study, the remains of involucral bracts of Coix from two Han...
Shear Stress Initiates Endothelial-to-Mesenchymal Transition in Endocardial Endothelial CellsNARA Subscribed
Discrete subaortic stenosis (DSS) is a congenital heart disease in which a fibrotic membrane forms below the aortic valve; the underlying cellular mechanisms are currently unknown. Since an elevated pressure gradient in the left ventricular outflow tract (LVOT) is a distinguishing feature of DSS, it is hypothesized that the membrane formation is caused by elevated wall shear stress applied to the endocardial endothelial cells...
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...
The midwater ocean (200 m depth to the seafloor) is the largest biome on the planet, supporting a large percentage of global ocean biomass. Difficulties in midwater exploration constrain knowledge about the organisms and ecology of the critical ecosystems it contains. Pacific Ocean expeditions by NOAA Ocean Exploration explored the faunal distributions of many water column taxa, including continued characterization of a zone o...
Chitinase-like proteins (CLPs) are of wide interest due to their significant roles during both homeostatic and pathological processes. Human CLPs such as YKL-40 have been proposed as biomarkers of disease severity in many conditions. Murine CLPs Brp39, Ym1, and Ym2 are similarly upregulated in multiple mouse models of pathology. Investigation of Ym1 and Ym2 is hampered by recent gene duplication events on the C57BL/6, but not...
