| 英文简介 | Desert darkling beetles (Coleoptera: Tenebrionidae: Pimeliinae) are an incredibly diverse (8,000+ described species) but poorly studied group of organisms that are found across the world, particularly in desert environments. Indeed, many species have evolved to survive in some of the driest and hottest places on Earth, and form a key component of desert ecosystems. The subfamily includes well known species such as Namibian fog basking beetles (Onymacris unguicularis, used in biomimicry research) and the North American blue death-feigning beetle (Asbolus verrucosus), along with thousands of poorly known or still undescribed species. This research will describe hundreds of species new to science, explore where these beetles live and how they are related to each other across the planet, and investigate the various adaptations that have allowed these beetles to thrive and diversify across the world's deserts. This project will also train a postdoctoral researcher, two Ph.D. students, and approximately 15 undergraduate students, as well as facilitating collaborations and providing training to a diverse group of scientists from across the globe. Project participants will also be designing and leading hybrid courses between Northern Arizona University and Namibia's renowned Gobabeb Research Center, and working to enhance research collections in all participating institutions. This project will resolve centuries-old issues in our understanding of desert darkling beetles by 1) generating DNA data from recently collected and museum specimens using high-throughput sequencing and target enrichment methods to recover ~631 genetic loci for approximately 500 species across the Pimeliinae. Additionally, approximately 300 larval and adult morphological characters will be scored for each species. Morphological data will be combined with the molecular data to reconstruct the evolutionary history of the subfamily. The resulting phylogeny will inform taxonomic decisions and help place current distributions and life histories within an evolutionary context. 2) Producing an Open Access electronic monograph of the subfamily using the mx/TaxonWorks bioinformatics platform and a matrix-based approach to coding and organizing morphological characters for descriptions, linked to the Coleoptera Anatomy Ontology (ColAO) to provide explicit definitions and images for anatomical terms. The monograph will include the first worldwide key to the Pimeliinae tribes and subtribes, images of specimens and characters, distribution maps, an extensive catalog of darkling beetle names and literature, and matrix-based descriptions. 3) Examining historical biogeography, diversification patterns, and adaptations to xeric conditions across the subfamily using the resulting phylogeny, over 20,000 georeferenced museum and modern specimens, and recently developed analytical tools for biogeographic analyses. This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria. |
