Evolutionary Developmental Leaf Morphology Of The Plant Family Araceae, Claudia Liliana Henriquez

Arts & Sciences Electronic Theses and Dissertations

Studying the evolutionary developmental morphology of leaves using next-generation phylogenetics, a candidate gene approach and comparative developmental studies in the plant family Araceae is the overarching theme of the dissertation.

The plant family Araceae is an ancient lineage from the Early Cretaceous and belongs to the monocotyledons. Members of Araceae display striking variation in leaf development; such variation contradicts traditional models of monocot leaf development. Additionally, dissected leaves, which are rare in monocots, seem to have evolved independently multiple times in Araceae by various developmental mechanisms.

Despite extensive efforts to elucidate the evolutionary history of Araceae, phylogenetic ambiguity in the …

Biological Flora Of Coastal Dunes And Wetlands: Borrichia Frutescens (L.) Dc., Robert I. Lonard, Frank W. Judd, Richard Stalter

Biology Faculty Publications and Presentations

Borrichia frutescens (L.) DC. is a New World warm-temperate, subtropical, and tropical zone, perennial subshrub that is an important species in hypersaline coastal sites. Also known as sea ox-eye, it tolerates salinities ranging from less than 20 ppt to 130 ppt. It occurs in substrates low in organic matter and deficient in nitrogen, phosphorus, and potassium. Nearly all reproduction is vegetative from an extensive rhizome system. Populations of this species recover quickly after coverage by wrack. Stands of B. frutescens often dominate the landward border of salt marshes.

Philornis Fasciventris (Wulp) (Diptera: Muscidae): Description Of The Male, Larva And Puparium, With Notes On Biology And Host Association, Marcia Couri, Troy Murphy, Richard Hoebeke

Troy G Murphy

The male, larva and puparium of Philornis fasciventris (Wulp) are described for the first time, as well as the larval habit and host association. The material was collected in Yucatan, Mexico in a nest of the turquoise-browed motmot, Eumomota superciliosa (Sandbach) (Coraciformes: Momotidae), first host record for this species. E. superciliosa is also a new host record for Philornis.

Behavioural Display Systems Across Nine Anolis Lizard Species: Sexual Dimorphisms In Structure And Function, Michele A. Johnson, Juli Wade

Michele A Johnson

Relationships between structure and function are a primary focus in biology, yet they are most often considered within individual species. Sexually dimorphic communication behaviours and the morphology of associated structures can vary widely, even among closely related species, and these traits provide an ideal opportunity to investigate the evolution of structure-function patterns. Using nine Anolis lizard species, we addressed a series of questions regarding sex differences in and the evolution of relationships between extension of the throat fan (dewlap) and morphology of the muscles and cartilage controlling it. The main results indicated that within species, males displayed the dewlap more …

The Reproductive Biology Of The Finetooth Shark, Carcharhinus Isodon, In The Northwest Atlantic Ocean, Amanda N. Brown

UNF Graduate Theses and Dissertations

Shark fisheries are a multimillion dollar industry in the United States and have significant contributions both recreationally and commercially. In order to maintain this industry, fisheries must be properly managed. An understanding of life history and reproduction is crucial in order to adequately manage shark fisheries. The finetooth shark, Carcharhinus isodon, is a member of the small coastal shark (SCS) fishery complex. It is found in Atlantic waters from South Carolina to Florida and throughout the Gulf of Mexico. This species has recently come under increased fishing pressure and has previously been overfished. New data is needed in order …

A New Species Of Sphaerowithius (Pseudoscorpiones, Withiidae) From Namibia, Mark S. Harvey, V. Menhert

Research outputs 2014 to 2021

A new species of Sphaerowithius Mahnert, 1988, S. ansieae sp. n., is described from specimens collected in caves in northern Namibia. The specimens show some slight modifications to an obligate cavernicolous existence including small eyes and long, slender pedipalps.
