The Effects Of Big Dune And Lava Dune Sand Composition On The Eggs And Larvae Of Pseudocotalpa Giulianii, Cosset Hernandez Pena, Mandy Mountain, Daniel B. Thompson
The Effects Of Big Dune And Lava Dune Sand Composition On The Eggs And Larvae Of Pseudocotalpa Giulianii, Cosset Hernandez Pena, Mandy Mountain, Daniel B. Thompson
Spectra Undergraduate Research Journal
Differences in the composition of aeolian sand at Big Dune and sand at Lava Dune that is mixed with basalt and various minerals may affect water retention and the development of insects that are specialized for living in sand environments. These two dunes, located in Nye County, Nevada, are home to the endemic dune scarab beetle, Pseudocotalpa giulianii (PSGU). The differences in sand type may influence the growth patterns of the eggs and larvae of this beetle species that hatches and develops to an adult within the sand. The purpose of this experiment is to test whether sand composition affects …
The Effects Of Habitat Isolation On Fine-Scale Genetic And Geographic Structure Of Populations Of Two Threatened Endemic Insects In Southern Nevada, Pseudocotalpa Giulianii And Icaricia Shasta Charlestonensis, Kristen Tovar
UNLV Theses, Dissertations, Professional Papers, and Capstones
Assessing the role geographic isolation and ecological specialization have on phylogeographic patterns contributes to our understanding of the evolutionary history of a species and the processes that erode genetic diversity. I used mitochondrial and nuclear genomic sequences to assess whether habitat isolation has shaped the fine-scale patterns of present-day genetic structure and diversity in two threatened insect species endemic to southern Nevada. Pseudocotalpa giulianii (Coleoptera; Scarabaeidae) is a dune obligate scarab beetle endemic to only two small, isolated sand dunes in Nye County, Nevada, with a usable habitat of less than 4.2 km sq that is impacted by on-going degradation. …
