Evaluation Of The Functional Capabilities Of Fins And Limbs For Moving On Land: Insights Into The Invasion Of Land By Tetrapods, Sandy Kawano
All Dissertations
Transitions to novel habitats present different adaptive challenges, producing captivating examples of how functional innovations of the musculoskeletal system influence phenotypic divergence and adaptive radiations. One intriguing example is the transition from aquatic fishes to tetrapods. Recent technological advances and discoveries of critical fossils have catapulted our understanding on how fishes gave rise to terrestrial vertebrates. Considerable attention has been paid to legged locomotion on land, but given that the first tetrapods were aquatic, limbs did not evolve primarily for terrestriality. How, then, is the locomotor function of limbs different from fins? Extant amphibious fishes demonstrate that fins can be …

Socioeconomic Indicators Of Family Forest Owner Use Of Federal Income Tax Provisions, John Hatcher
All Dissertations
Family forest owners control a majority of the South's forest land and nearly half of its growing stock. These owners are a diverse group with widely varied objectives for ownership and management. Many family forest owners manage their holdings for timber production objectives and thus, are concerned with issues such as reforestation incentives and tax treatment of timber revenues. Their actual knowledge of the tax aspects of timber management varies, with some owners unaware of the federal income tax provisions that apply to timber. This study uses econometric techniques to establish socioeconomic predictors of family forest owner use of seven …
