The functional morphology of Axiothella rubrocinta (Johnson)
<p>The family Maldanidae is a group of sedentary polychaetes having a cylindrical body with elongate, but relatively few segments. The prostomium has a dorsal pair of nuchal organs and may have eye-spots ventrally; true appendages are absent. The mouth opens ventrally on the peristomium and has an …

Functional morphology of the anthropoid talocrural joint
… suggest that these aspects of talocrural joint functional morphology are not associated with climbing in extant anthropoids, and cannot be used in isolation to predict behavior of fossil taxa. Although this research has evaluated only broad, pairwise contrasts between diverse groups of extant …

The functional morphology and ecology of Chone mollis
<p>Chone mollis occurs in large numbers in Tomales Bay and is an ecologically important infaunal member of the bay community. As with most marine communities, very little work has been done with individual species of the community. The present study of C. mollis is a contribution towards an …

The evolution and functional morphology of trap-jaw ants
… four chapters and investigates the evolution and functional morphology the highly specialized mouthparts of trap-jaw ants. In Chapter 1, I review the current literature on trap-jaw ant taxonomy, phylogenetics, and biomechanics. The trap-jaw morphology has independently evolved at least four times …

Systematics, biogeography and functional morphology of the Box Crabs (Family Calappidae)
… the family and to examine the phylogenetic and functional implications of the oxystomatous condition in an evolutionary and biogeographic framework. The systematic status of the family Calappidae and the phylogenetic relationships of its four component subfamilies were re-evaluated based on a …

Ultrastructure and functional morphology of adhesive organs and anti-adhesive plant surfaces
… hamper the attachment of animals. Knowledge of morphology, ultra-structure, surface structure and physical properties such as stiffness and elasticity are essential for understanding both of these two systems. The aim of this study was to characterize the surface structures and properties of …

The functional morphology of insect adhesive devices and its implications for ecology
The aim of this thesis is to gain a better understanding of the constraints that affect insect adhesion with an emphasis on biological constraints such as plant defences against insects and the influence of abiotic factors on insect foraging. In chapter one of this theses, a literature review on …

A qualitative and quantitative investigation of the functional morphology of the juvenile scapula
… a radiographic description of developmental morphology of the human scapula and a comprehensive morphological description of trabecular bone in the perinatal scapula. While the aim was originally to describe the changing trabecular morphology in the developing scapula, considerable thought …

Comparative biomechanics and functional morphology of latch-mediated spring actuated mandibles in ants
… However, there is a lack of information on functional morphology and mandible kinematics for many of these trap-jaw ant groups and species, particularly in the subfamily Myrmicinae which contains the majority of trap-jaw ant species. My dissertation consists of four chapters and investigates …

Structure, function, and functional morphology of Mitra idae Melvill 1893 and M. catalinae Dall 1920
<p>The morphology of the proboscis--particularly the epiproboscis, the feeding behavior, the function(s) of the epiproboscis, and the functional morphology of the epiproboscis, were studied in Mitra idea Melville and fi. catalinae Dall (Gastropoda: Neogastropoda; Mitridae.</p> <p>In M. idae, the …

Functional morphology of mammalian sacra and caudal vertebrae : implications for tail loss and positional behaviors in extinct primates
… strength of the comparative method for testing functional hypotheses. The goal of this dissertation is to identify anatomical correlates of tail length and positional behaviors from sacral and caudal vertebral morphology among primates and other mammals in three studies. The first study examines …

Functional Morphology of the Sphyrnid Shark Cephalofoil: an Assessment of the Hydrodynamic Lift Hypothesis Using Computational Fluid Dynamics
… Many theories have been proposed regarding the functional aspects of this structure. One of these is that it may produce beneficial dynamic lift as the shark swims (in similar fashion to the cambered wings found on many modern-day aircraft). As sharks do not possess a swim bladder, part of their …

Comparisons of Secondary Production, Life History, and Mouthpart Functional Morphology Between Two Populations of the Amphipod Gammarus minus
In this study, features of ecology, behavior, and functional morphology related to feeding activity of two populations of the amphipod Gammarus minus were compared. The two populations occupied different habitats, and I attempted to determine whether differences observed between the two populations …

The importance of cotyledon functional morphology and patterns of seed reserve utilization for the physiological ecology of neotropical tree seedlings
Seed mass, resource makeup of seed, and functional morphology of cotyledons are three traits that together determine patterns of seed reserve utilization by seedlings during their critical establishment stage. The main objective of this thesis is to examine how these traits differentiate the …

Taxonomy, Functional Morphology and Paleoecology of the Fenestellidae and Polyporiidae (Fenestelloidea, Bryozoa) of the Warsaw Formation (Valmeyeran, Mississippian) of the Mississippi Valley
Fenestellid and polyporid Bryozoa of the Lower Mississippian Warsaw Formation of the Mississippi River outcrop belt are represented by nine genera of Fenestellidae (three of which are new--Banastella, Cubifenestella, and Apertostella) and two genera of Polyporidae. Twenty-two previously described …
