Synthesis and degradation of polyhydroxybutyrate (PHB) under different nutrient combinations in the alphaproteobacterial methanotroph, Methylocystis sp. Rockwell
DownloadFall 2023
Methane emissions and plastic pollution are two distinct environmental issues that arise from human activities. The ongoing increases in methane emissions and its atmospheric concentration pose a major environmental threat as methane is a potent greenhouse gas, with a warming effect 28 times...

Systematics and diversity of Ichneumonidae, with an emphasis on the taxonomically neglected genus Ophion Fabricius
DownloadFall 2013
Ichneumonidae are the most species-rich family of parasitic Hymenoptera and are important for regulating populations of other arthropods. However, with an estimated 75% of species undescribed, we lack fundamental information about their taxonomy, ecology, and distributions. Using two different...

Systematics and palaeobiology of the crested hadrosaurine Saurolophus from Canada and Mongolia
DownloadFall 2011
Reappraisal of Saurolophus confirms Saurolophus osborni and Saurolophus angustirostris as distinct species. Synapomorphies of Saurolophus include a spike-like pseudonarial crest formed by the nasals, frontals, and prefrontals; tripartite frontals with anteroventral and posterodorsal extensions...

Systematics of an Oligocene-Aged Fossil Snake Assemblage from the White River Formation, Wyoming
DownloadSpring 2014
Extinct snake taxa are primarily recognized from isolated vertebrae. A new specimen from the Oligocene of Wyoming provides a rare opportunity to examine four nearly complete and articulated fossil snakes. Informally assigned previously to the ‘erycine’ vertebral form taxa Ogmophis and...

Systematics of Clupeomorpha (Osteichthyes:Teleostei) with methodological considerations for morphological phylogenetics
DownloadFall 2020
Here I conduct a systematic revision of Clupeomorpha, a group of bony fishes that includes over 500 living and extinct species of herrings, sardines, anchovies, and their relatives. Despite a long history of research on clupeomorph fishes, evolutionary relationships within the group remain poorly...

Living platynotan lizards are represented by two families: Helodermatidae, consisting of two species limited to south-western North America and north-western Central America; and Varanidae, with 54 species distributed throughout Africa, south-east Asia and Australia. Modern members of Platynota,...

The name, mosasaurs, generally refers to a group of extinct, highly aquatically adapted and large-bodied squamates that lived exclusively during the Late Cretaceous, approximately from 93 to 65 million years ago, in the oceans worldwide. Plioplatecarpines (Plioplatecarpinae) were medium-sized...
