Baleen Whale Occurrence in the Waters Off Virginia and North Carolina, U.S.A. From 2001 to 2019NARA Subscribed
Eighteen years of visual survey and strandings data were used to describe baleen whale occurrence along the continental shelf of Virginia and North Carolina, U.S.A. This region experiences heavy anthropogenic use, which poses risks for mortality and injury to baleen whales. Between 2001 and 2019, six species of baleen whales were recorded, and whales occurred year‐round. The total number of (on‐ and off‐effort) sightings and s...
Groundwater is the Earth’s largest reservoir of available freshwater. As climate change and increasing anthropogenic pressures continue to affect its availability and quality, the discipline of hydrogeology is evolving rapidly. Training enough professionals capable of understanding and managing groundwater resources effectively is therefore more critical than ever. However, there is a perceived global shortage of adequately tr...
Potato dormancy is a major obstacle in post-harvest evaluations for the certification of seed. Objectives of this study were to evaluate the efficacy of several treatments to break dormancy and induce sprouting soon after harvest for Russet Burbank, Clearwater Russet, and Umatilla Russet. Treatments included: (a) control held at 18.3 C, (b) cold-stratification held at 4.4 C for two weeks, (c) temperature fluctuation held at 4....
Development of Potato Bruises as Influenced by Cultivar, Impact Height, and Holding TemperatureNARA Subscribed
Handling potatoes at harvest and throughout transloading operations can result in two main impact injuries: blackspot and shatter bruises. The objective of this study was to examine the development of blackspot and shatter bruises over a 24 to 48-h period as influenced by cultivar, impact height and holding temperature with the intent to identify whether more rapid, on-farm bruise evaluations could be used to facilitate change...
In many settings, head and neck cancer (HNC) services are centralized in large hospitals, meaning that community input from HNC specialists can be lacking. Community healthcare professionals often require laryngectomy-specific education and training to provide optimal care to people at home. However, laryngectomy-specific education/training is often sporadic and varies between centres, making it difficult to achieve standardis...
Response of Soil Chemistry to Long-Term Occupancy by Introduced Pinus Species in Hardwood ForestsNARA Subscribed
Conifers have been widely planted to stabilize soils and promote site recovery on former hardwood sites that were cleared for agriculture. Decades of confer occupancy may have lasting effects on nutrient availability, organic matter cycling, soil acidity, and soil buffering capacity. In many areas of eastern North America, conifer plantings consisted of non-native Pinus species planted on abandoned agricultural land that was o...
Effective sprout inhibitors are increasingly needed in potato production due to regulatory changes restricting widely used chemistries such as chlorpropham (CIPC), with direct implications for storage management and international trade. Ethylene has emerged as a potential alternative, since it is naturally occurring in plants and exhibits sprout suppressant activity, though commercial outcomes may vary. To evaluate its effecti...
Utilizing Exhaled Breath and Skin Microbiomes in Assessments of At‐Risk Killer Whales ( Orcinus orca )NARA Subscribed
For at‐risk populations of killer whales ( Orcinus orca ), biological samples can offer information about individual animal status. We hypothesized that low‐yield samples could provide sufficient material for microbiome analysis. We collected and analyzed, with amplicon metabarcoding, breath samples from managed care and free‐ranging killer whales (8 and 14 animals, respectively) and epidermal tissue from free‐ranging killer w...

Summer Diet of Humpback Whales in the Northern Strait of Georgia, British Columbia (Canada), Revealed by Stable Isotope AnalysisNARA Subscribed
North Pacific humpback whales ( Megaptera novaeangliae ) have recovered rapidly following their depletion by commercial whaling. Diet studies are necessary to assess food web implications of their recovery. This study investigates the diet composition of humpback whales foraging in the northern Strait of Georgia, British Columbia, Canada, an area experiencing a recent return of humpback whales. Humpback whale skin samples ( n...
Vascular smooth muscle cells (SMC) comprise the medial layer of blood vessels and are responsible for maintaining vascular tone. Ordinarily quiescent and contractile, SMC can dedifferentiate into different phenotypes following injury or in disease states such as atherosclerosis and are thus valuable research tools for examining these conditions. The isolation of commonly used SMC types, such as those from the aorta or saphenou...
Influence of Mother Seed Tuber Size on Yield and Incidence of Seedborne Potato Virus YNARA Subscribed
Potato virus Y (PVY) is an important pathogen in seed potato production that may cause seed lots to be downgraded or rejected for certification. A study was conducted to determine if mother seed tuber size influences the prevalence of PVY within a seed sample during evaluations of seed-borne infection in a grow-out. The trial was conducted using Russet Norkotah (two growing seasons) and Umatilla Russet (one growing season). Se...
Aeolian sand transport on beaches is strongly affected by surface moisture, but its influence on transport evolution remains poorly understood. We present a novel discrete particle modeling framework to systematically investigate how moisture from liquid bridges affects the development of transport toward steady state after initiation. Moist sediment particles are modeled using a particle-based approach with evolving liquid br...
