With anatomical and functional studies we have shown that jumping behavior and pelvic anatomy have evolved in a stepwise fashion in frogs. Frogs first evolved jumping with a belly-flopping landing and later evolved feet first landing. Frog pelvic design has evolved too going from a hopping system to many versions of jumping and climbing pelvic systems.

Evolutionary and Functional Morphology
My research integrates morphological, biomechanical, functional, and developmental analyses to study how ontogeny, ecology, and phylogeny affect vertebrate design and function. This involves experimental and morphometric approaches to the analysis of form and function in organisms, testing organismal performance in the lab and field, and ecomorphological approaches to the study of vertebrate evolution.
Please see our websites for information for Graduate and Undergraduate programs of study. Ohio University and the Department of Biological Sciences offers several avenues for undergraduate research opportunities, funding, and honors research programs.

Lizard Ecology: The evolutionary consequences of foraging mode (published August 2007)
Edited by Steve Reilly, Lance McBrayer, and Don Miles
The foraging mode of lizards has been a central theme in guiding research in lizard biology for three decades. Foraging mode has been shown to be a pervasive evolutionary force molding the diet, ecology, behavior,
anatomy, biomechanics, life history and physiology of lizards. This volume reviews the state of our knowledge on the effects of foraging mode on these and other organismal systems to show how they have evolved, over
a wide taxonomic survey of lizard groups. The reviews presented here reveal the continuous nature of foraging strategies in lizards and snakes, providing the reader with an up-to-date review of the field, and will equip
researchers with new insights and future directions for the sit-and-wait vs. wide foraging paradigm.

Anatomy and Morphometrics Research
Morphology is analyzed using a computer-interfaced video and radiographic analysis systems and quantitative morphometrics to describe and compare individual structures and their shapes. Development is quantified by tracking anatomical structures visualized in specimens using conventional staining and clearing techniques and micro CT imagery.
Much of my past research has focused on the metamorphosis of cranial
morphology and feeding function in lower vertebrates, the evolution of neoteny and paedomorphosis in salamanders, and the use of ontogenetic
morphological data in systematics. My
new student Mike Jorgenson
is finishing a widespread comparison of skeletal anatomy and muscle fiber
types in frogs as it relates to locomotion..
My new student Mike Jorgenson is finishing a widespread comparison of skeletal anatomy and muscle fiber types in frogs as it relates to locomotion..
Previous students have studied lizard limb anatomy in relation to gait, biomechaincs and actual locomotor relevance in the field (Eric McElroy), correlates of head design and foraging mode in lizards (Lance McBrayer), a comparative analysis of the functional morphology and biomechanics flying squirrels (Rick Essner), and an analysis of the tadpole head anatomy and function (Pete Larson).
Functional Morphology and Performance
Simultaneous high-speed video and radiography (100 - 1000 fields per second) and electromyography (up to 14 channels) are used to quantify behavioral movements and muscle activity patterns. Custom software are used to digitize and quantify kinematic and EMG data. Organismal performance is tested in the laboratory and the field to link morphology to ecology and resource use. The integration of these approaches allows empirical tests of a broad spectrum of biological phenomena and hypotheses.

Force Plate Technologies for studying whole body mechanics
Many of our studies have used force plate systems from which ground reaction forces can be recorded in small
vertebrates. We are recording data from a variety of vertebrates including possums, lizards, salamanders, and
tuataras, and recently toads! These devices and virtual instruments are used to record, scale and filter force
records and to crunch mechanical energy fluctuations were developed with National Science Foundation support
with the assistance of John Bertram, David Lee, and Kay Earls . In addition, a new force instrumented treadmill
system is now up a running.
Functional morphological data quantifying kinematic, motor pattern and force dynamics form a necessary basis
for convincing functional inferences that can be used to test hypotheses about biomechanics, the evolution of
terrestrial feeding and locomotion and how the ecological relevance influences the evolution vertebrate form
This shot is for you, Kay!
Integrative studies of locomotor behavior, gait, mechanics, and motor patterns
Much of the recent work in the lab has focused on analyses of vertebrate locomotion in collaboration with Dr.
Audrone Biknevicius. The general goal is to examine the effects of the "sprawling to erect" paradigm in tetrapods
birds and studies of these taxa are currently underway. Eventually, we will be able to describe in more detail
how each of these taxa move and to compare and contrast anatomical and functional patterns on the vertebrate
Recent studies have shown that tail dragging in alligators has wide ranging effects on hindlimb function. And
possums were found to utilize only running mechanics and trotting gaits. In addition, possums were also found
to use a “cross-couplet” linkage system to stiffen the body across diagonal limb couplets during each step.
Recent studies of new world and Australian marsupials has revealed size constraints on mammalian locomotion
and has shown how mammals may have transitioned from the cross-couplet system to the placental mammal
See Science 299:400-403. or the following popular press reports:

This work has led into our current studies oflocomotor constraints and innovations in primitive mammals
In collaboration with Tom White (Buffalo State College) and Mike Bennett (University of Queensland) we are
studying locomotor system in marsupial and placental mammals in which different constraints and innovations
appear to have molded the evolution of locomotor design, gaits and the use of mechanical energy-saving systems.
Integrated studies of anatomy, gait, limb and axial movements, muscle activity patterns, ground reaction forces and
whole-body mechanics will compare locomotor dynamics in two important examples of evolutionary transitions of
vertebrate locomotion: from the primitive tetrapod condition to early mammalian forms and between marsupials and
The work follows up on discoveries from previous NSF support showing that the “epipubic” bones lying the belly
wall in front of the pelvis and associated abdominal muscles function in a “cross-couplet system” controlling trunk
bending and footfall patterns during locomotion. The advent of the cross-couplet system (based on the appearance
of epipubic bones) and its subsequent retention in all basal mammalian taxa reveals a significant and as yet
unrecognized critical innovation in the transition from generalized amniote to mammalian patterns of locomotion.
Appearing concomitantly with the key mammalian traits of endothermy, mastication and lactation, the cross-couplet
system is hypothesized to have been a key locomotor innovation leading to the early radiation of mammals. It
remains a viable locomotor system in many primitive mammals, however, the subsequent reduction or loss of the
epipubic bones (and we propose the loss of the cross-couplet system and its constraints) appears to have freed
some marsupials and the extant eutherians from the locomotor constraints on gait and mechanics predicted for
cross-couplet system. Understanding the locomotor consequences of the appearance and subsequent loss of the
epipubic bones is therefore of great significance in mammalian evolution. Quantifying the functional consequences
of changes in early mammalian belly design is critical to understanding the radiation of locomotor abilities in higher
Evolutionary biomechanics in tetrapods
Recent studies of locomotor biomechanics have added to our knowledge about the distribution of walking
(vaulting - pendulum-based locomotion) and bouncing (spring-like locomotion) across tetrapods and show that
these basic energy-saving mechanisma appeared with the first tetrapods to move onto land over 200 million years ago.

how these patterns have evolved each time wide foraging modes appear
