Divergent Selection on Dispersal Targets Chemosensory and Neuronal Genes in Tribolium castaneumNARA Subscribed
Dispersal is key to the life history, ecology and evolution of many organisms and important in pest invasiveness. However, the genetic architecture underlying variation in dispersal behaviour remains poorly understood outside of a few model species. We investigated the genomic basis of dispersal using artificial selection on replicated lines of Tribolium castaneum , a flour beetle, an emergent model system and an economically...
Understanding changes to local communities brought about by biological invasions is important for conserving biodiversity and maintaining environmental stability. Scale insects (Hemiptera: Coccoidea) are a diverse group of insects well known for their invasion potential and ability to modify local abundance of multiple insect groups. Here, we tested how the presence of crape myrtle bark scale ( Acanthococcus lagerstroemiae, CM...
Drone‐Based Photogrammetry Provides Estimates of the Energetic Cost of Migration for Humpback Whales Between Antarctica and ColombiaNARA Subscribed
Monitoring the body condition of animals offers insights into their energetic needs, prey consumption, and vulnerability to environmental pressures. Southern hemisphere humpback whales ( Megaptera novaeangliae ) depend on Antarctic krill for their annual energy requirements. Drone‐based photogrammetry was used to assess the energetic cost of migration and reproduction for breeding stock G humpback whales. Body measurements of...
Nutrients on the move: Investigating large scale fatty acid exports from European ponds via emerging insectsNARA Subscribed
Permanent ponds are key landscape units that supply various ecosystem services. Notably, the export of aquatic subsidies to land via emerging insects may significantly influence terrestrial food webs. Polyunsaturated fatty acids (PUFA), which enhance consumer fitness, are among the essential exported components. The patterns and drivers of dietary exports from ponds via insects remain poorly known, particularly at continental...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Time to rethink trophic levels in aquaculture policyNARA Subscribed
Aquaculture policy often promotes production of low‐trophic level species for sustainable industry growth. Yet, the application of the trophic level concept to aquaculture is complex, and its value for assessing sustainability is further complicated by continual reformulation of feeds. The majority of fed farmed fish and invertebrate species are produced using human‐made compound feeds that can differ markedly from the diet of...
Efficiently Simulating an Endograft Deployment: A Methodology for Detailed CFD AnalysesNARA Subscribed
Numerical models of endografts for the simulation of endovascular aneurysm repair are increasingly important in the improvement of device designs and patient outcomes. Nevertheless, current finite element analysis (FEA) models of complete endograft devices come at a high computational cost, requiring days of runtime, therefore restricting their applicability. In the current study, an efficient FEA model of the Anaconda™ endogr...
