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...
Gulf sturgeon are federally listed as “threatened” and are native to seven rivers along the northern Gulf of Mexico. Populations natal to the Pascagoula River have one verified spawning reach in the lower Bouie River, near Hattiesburg, MS. This reach is modified by four aggregate mining areas, referred to as pits. Researchers observed post-spawn Gulf sturgeon over-summering in pits rather than migrating to downstream holding a...
Behavioral variation across multiple phases of intravenous cocaine self-administration among genetically diverse mouse populationsNARA Subscribed
Genetic and other predisposing factors can influence the progression from initiation of drug intake to compulsive substance use through distinct biobehavioral processes. Operant cocaine self-administration studies in laboratory mice offer a powerful method to dissect the biology of this progression from initiation, dose-response, extinction, and cued reinstatement in a controlled, tractable system. However, many such studies e...
Microbiome Structure of Endemic Hawaiian Drosophila Is Shaped More by Habitat Than Host IdentityNARA Subscribed
The Hawaiian Drosophila radiation exemplifies rapid adaptation and species diversification. Many factors have been attributed to these phenomena, including allopatry, sexual selection, and ecological specialization. In recent years, the microbiome has come to the forefront as an important driver of adaptation that is capable of facilitating host survivorship, enhancing resilience to local environmental challenges, and enabling...
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 estimates of the sensible and latent heat fluxes are explored for two semi-arid locations using standard measurements of temperature and humidity at two levels in the surface layer. The sensible heat flux estimated with the stability functions proposed by Businger has values within the tolerable error in complex terrain, except when the surface is wet and irradiation is high. These cases correspond to a regime dominated by...
Entanglement is one of the primary anthropogenic threats to the North Atlantic right whale ( Eubalaena glacialis ; right whale) whose habitat overlaps fixed-gear fishing grounds in the Northwest Atlantic with entanglements representing around half of the mortality and serious injury incidents. Right whale mortality has reached levels that require intervention under the Marine Mammal Protection Act, creating the need for a tool...
