The Ecology And Evolution Of Species Rarity In Oaks (Quercus Spp.), Yingtong Wu
The Ecology And Evolution Of Species Rarity In Oaks (Quercus Spp.), Yingtong Wu
Dissertations
Rare species are susceptible to extinction due to ecological and genetic factors. Understanding the distribution, ecology, and evolution of rare species can provide useful information for effective conservation. To investigate species rarity, this dissertation focuses on a species-rich and ecologically diverse genus, Quercus (oaks). In Chapter 1, I aimed to understand how interactions between hosts and soil microbes contribute to habitat restriction in oak species. I performed a soil inoculum experiment on two pairs of sister oak species that show habitat divergence. I found that host-specific soil microbes contribute to habitat divergence and exclusion among sister species of oaks, but …

The Taxonomic Report of the International Lepidoptera Survey
The comparative genomics of butterflies yields additional insights into their phylogeny and classification that are compiled here. As a result, 3 genera, 5 subgenera, 5 species, and 3 subspecies are proposed as new, that is, in Hesperiidae: Antina Grishin, gen. n. (type species Antigonus minor O. Mielke, 1980), Pompe Grishin and Lamas, gen. n. (type species Lerema postpuncta Draudt, 1923), and Curva Grishin, gen. n. (type species Moeris hyagnis Godman, 1900); in Lycaenidae: Fussia Grishin, subgen. n. (type species Polyommatus standfussi Grum-Grshimailo, 1891) and Pava Grishin, subgen. n. (type species Thecla panava Westwood, 1852); in Hesperiidae: Monoca Grishin, subgen. n. …

All HCAS Student Capstones, Theses, and Dissertations
Knowledge of community assemblages and biodiversity is important for monitoring health and resilience in an ecosystem. Taxonomic and functional biodiversity of mesopelagic (200- 1000 m) fishes is extremely rich in the Gulf of Mexico. The aim of this study was to compare calculations of biodiversity and community structures at varying taxonomic resolutions for deep pelagic fishes to inform future decisions about deep-sea ecosystem monitoring. This study analyzed biodiversity and assemblage structure patterns from a biological inventory of deep-sea fishes collected with a large mesh, commercial-sized, high-speed rope trawl in the Gulf of Mexico between June 21st and July 14 …

The Taxonomic Report of the International Lepidoptera Survey
We present an analysis of the names proposed by Carl Plötz in 1884 for the New World species in the genus Pyrgus Hübner, [1819] facilitated by the genomic sequencing of extant primary type specimens comparatively with a larger sample of more recently collected specimens of these species and their relatives. The changes to nomenclature suggested here are only caused by the identity of primary type specimens as revealed by their phenotypes or though genomic sequencing. All neotypes are designated to stabilize nomenclature in agreement with the current usage of these names, which in unison agrees best with the information available …
