Modeling Red Blood Cell Deformation at Supraphysiological Strain Rates Using a Droplet FrameworkNARA Subscribed
Purpose Hemolysis remains a concern in mechanical circulatory support devices (MCSDs). Capturing flow-induced red blood cell (RBC) deformation is important to improve these technologies. Deformation models that are feasible for macroscale MCSD flows have not been calibrated with human RBC deformation data across multiple conditions. The purpose of this study is to modify and test a droplet deformation model that is applicable...
Genome-wide markers test the status of two putative species of North American bumble beesNARA Subscribed
Accurate species delimitation is critical to identifying the conservation status of species. Molecular species delimitation methods have revealed previously unrecognized cryptic species across the taxonomic spectrum. However, studies vary in the molecular markers selected, analytical approaches used, and taxon sampling, which sometimes results in conflicting conclusions. One example of such a conflict is seen in the species de...
Spatial variation in the effects of size and age on reproductive dynamics of common coral trout Plectropomus leopardusNARA Subscribed
The effects of size and age on reproductive dynamics of common coral trout Plectropomus leopardus populations were compared between coral reefs open or closed (no‐take marine reserves) to fishing and among four geographic regions of the Great Barrier Reef ( GBR ), Australia. The specific reproductive metrics investigated were the sex ratio, the proportion of vitellogenic females and the spawning fraction of local populations....
Rust disease of eucalypts, caused by P uccinia psidii , did not originate via host jump from guava in B razilNARA Subscribed
The rust fungus, P uccinia psidii , is a devastating pathogen of introduced eucalypts ( E ucalyptus spp.) in Brazil where it was first observed in 1912. This pathogen is hypothesized to be endemic to S outh and C entral A merica and to have first infected eucalypts via a host jump from native guava ( P sidium guajava ). Ten microsatellite markers were used to genotype 148 P . psidii samples from eucalypts and guava plus five a...
A simple plant mutation abets a predator‐diversity cascadeNARA Subscribed
Resource consumption often increases with greater consumer biodiversity. This could result either from complementarity among consumers or the inclusion of particular key species, and it is often difficult to differentiate between these two mechanisms. We exploited a simple plant mutation (reduced production of surface waxes) to alter foraging within a community of aphid predators, and thus perhaps shift the nature of resulting...
Ecology Letters (2010) 13: 338–348 Abstract More diverse communities of consumers typically use more resources, which often is attributed to resource partitioning. However, experimentally demonstrating this role of resource partitioning in diverse communities has been difficult. We used an experimental response‐surface design, varying intra‐ and interspecific consumer densities, to compare patterns of resource exploitation bet...
