Bonamia ostreae in New Zealand: Lessons From a Decade‐Long Marine Biosecurity ResponseNARA Subscribed
When Bonamia ostreae (Haplosporidia) was first detected in New Zealand flat oysters ( Ostrea chilensis ) in 2015, it threatened one of the world's largest remaining wild flat oyster fisheries in Foveaux Strait and a developing aquaculture sector. Following the subsequent spread of the parasite within New Zealand from the index site (Marlborough Sounds) to Big Glory Bay, Stewart Island, directly adjacent to Foveaux Strait, New...
Delta Wing‐Shaped Upper Jaw as a Control Surface to Stabilize Rorqual Whales During Lunge‐FeedingNARA Subscribed
During lunge feeding, rorquals depress their lower jaw to fill the buccal pouch, which can produce a downward pitch on the body from a drag force below the center of mass. It is hypothesized that without flippers the raised upper jaw could produce a counteracting lift to trim the body. Upper jaws of the blue whale and humpback whale have triangular shapes that resemble delta wings. Such wings generate lift without stalling at...
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...
Decomposition of plant litter, facilitated primarily by microbial decomposers, plays a critical role in biogeochemical cycling and ecosystem function. The rate of litter decomposition can determine its environmental impact, where accelerated decomposition alters the timing and rate of nutrient release and may promote nutrient leaching, whereas slowed decomposition can result in litter accumulation, which impacts seedling recru...
A Proposed Novel Neurovascular Mechanism for Brain Network Dysfunction After Traumatic InjuryNARA Subscribed
Current research in predicting traumatic brain injury risk focuses on the relationship between head impacts and the likelihood of white matter damage, often overlooking the role of neurovascular coupling in the injury response. To fill this gap, we combined biomechanical and neurodynamic principles to simulate alterations to large-scale resting-state brain activity following head impacts. We simulated cortical neural activity...
Deeper Caribbean reef fish communities show greater taxonomic and functional change in dominance structure over a nine-year periodNARA Subscribed
Fish communities at greater depths on a reef are thought to be less affected by disturbances that more strongly impact shallower areas. As a result, these deeper communities might be expected to show less change in their diversity and composition over time compared to those in shallow water. To test this hypothesis, we analysed changes in reef fish composition at 5-15 m and 25-40 m on reefs around Utila, Honduras, across two t...
Upstate Abundance is a fresh market white-fleshed potato cultivar with resistance to both pathotypes Ro1 and Ro2 of the golden cyst nematode ( Globodera rostochiensis ) as well as to late blight ( Phytophthora infestans ) lineage US-23. It was selected from a cross made at Cornell University in 2000 between the Cornell breeding clone NY121 and the fresh-market cultivar Jacqueline Lee and released by the New York Agricultural E...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Polymyxins remain indispensable last-line antibiotics for multidrug-resistant Gram-negative infections, yet their clinical use in central nervous system (CNS) infections is constrained by poorly understood neurotoxicity. Here, we define the early molecular signalling events underlying polymyxin B-induced CNS toxicity using an integrated phosphoproteomic and Reverse Phase Protein Array (RPPA) approach in rat brain following int...
