Improving predictions of rainfall-triggered debris flows using area-based probability intensity curvesNARA Subscribed
Rainfall-triggered debris flows represent one of the greatest growing threats to co-located populations, infrastructure, and communities on or adjacent to steep slopes worldwide. Landslide-triggering rainfall thresholds are formulated to provide practical warnings of debris flow hazards. Statistical models, intensity-duration (I-D) curves or some adaptation thereof, account for about 70% of the methods used to define these thr...
Transformation system optimization and introduction of a new model Eucalyptus grandis x urophylla genotype for transgenic studiesNARA Subscribed
A number of factors that have been reported to affect transformation/regeneration rate in plants were studied in multiple eucalypt genotypes. These include surfactant, acetosyringone, fipexide, basal media, activated charcoal, ascorbic acid, lipoic acid, proline, cytokinins, sugars, spectinomycin selection, Agrobacterium strains and concentrations, forchlorfenuron, PVP, silver nitrate, and explant heating prior to cocultivatio...
Radiopaque microsphere-hydrogel composite for extended-release intratumoral immunotherapy in a large animal modelNARA Subscribed
Intratumoral injection of immune stimulants could potentially reverse the immunosuppressive tumor microenvironment, but the injected drug rapidly washes out into the systemic circulation. This results in systemic toxicity, and reduced efficacy, potentially requiring daily injections to generate an antitumor immune response. To address this problem, we developed an extended-release hydrogel that retains the immunotherapy agent...
Understanding how marine species tolerate ocean acidification (OA) is critical for predicting biological responses to ocean change, as well as impacts on the ecosystems and industries that rely upon them. Snow crab ( Chionoecetes opilio ) are both a major fishery resource in the Bering Sea and an important component of high-latitude marine food webs. Experimental work suggests that snow crab are relatively tolerant of OA, but...
A captive‐reared cohort of Laurel Dace, Chrosomus saylori (Skelton 2001) (Cypriniformes: Leuciscidae), a federally‐endangered species endemic to several streams in eastern Tennessee's Cumberland Plateau, exhibited signs of morbidity and trickling mortalities in a recirculating aquaculture system. Ziehl‐Neelsen (ZN) staining revealed acid‐fast rod‐shaped bacteria within necrotic and intracellular lesions affecting the eye, swim...
Introduction Understanding migration timing and movement behavior is critical for predicting population responses to environmental changes. The beluga whale ( Delphinapterus leucas ) population in Cumberland Sound, Nunavut, is currently endangered due to historical and ongoing overharvesting. Methods By comparing satellite telemetry data from two distinct time periods (1998–1999 and 2006–2008), we evaluated beluga whale dive b...
In a rapidly warming Arctic, genetic variation might serve to buffer organisms against the effects of environmental change, such as sea ice loss and ocean warming. Yet, this concept remains largely unexplored because comprehensive genome‐wide studies across the full ranges of Arctic marine taxa are rare. Bowhead whales ( Balaena mysticetus ) have a strong association with sea ice and polar water masses, a long history of human...
