  Paul Buchheim - Deciphering Lacustrine Stromatolites: Paleo-lake Hydrodynamics and Chemistry

  Southern Adventist University

  Stromatolites are microbial build-ups that were known only as fossils until modern living analogs were reported in 1961 from Shark Bay, Australia. Since then, modern stromatolites have been described from numerous locations including Wyoming, Utah, and Colorado. Current studies provide a unique picture of ancient lake hydrodynamics and chemistry not previously understood and have motivated significant revisions in depositional models of this ancient lake system.

  Carol Buckley - Sanctuary: A Captive Elephant's Only Acceptable Alternative

  Southern Adventist University

  There is a crisis facing elephants in captivity and in their home ranges. The goal of the directors and staff of The Elephant Sanctuary is to provide a haven for old, sick or needy elephants. The elephants live in a setting of green pastures, old-growth forests, spring-fed ponds and a heated barn for cold winter nights. In addition to the care of the animals, Carol and her staff work to provide education about the crisis facing these social, intelligent and endangered creatures.

  David Lindsey - Stress in the Life of a Social Amoeba: A Model for Understanding Developmental and Neurological Disorders

  Southern Adventist University

  Dictyostelium, a social amoeba, normally exists as solitary cells that proliferate by cell division while feeding on bacteria in soil and decaying leaves. When stressed by starvation, these amoebae stop dividing and enter a developmental program that results in the formation of a multicellular fruiting body.

  Jennie Janssen - From Taiwan to Atlanta: The Story of Georgia Aquarium's Whale Shark Acquisitions

  Southern Adventist University

  The whale shark is the world’s largest fish, reaching lengths of up to 66 feet. The species of shark at the Georgia Aquarium, Rhincodon typus, is a gentle filter-feeding species. Found world-wide in tropical and subtropical waters, the whale shark is gray to brown in color with light yellow or white markings and a white belly. Ms. Janssen tells how the whale shark was acquired and transported from Taiwan to Atlanta.

  Marcus Ross - Sea Dragons, Fire, and Brimstone: The Life and Times of Mosasaurs

  Southern Adventist University

  Dr. Ross has continued researching about a group of extinct marine reptiles called mosasaurs. He is greatly interested in issues surrounding the creation-evolution controversy and the intersection of geology with the Biblical events of creation and Noah’s Flood.

  Richard Seidel - Uniting Ecology and Genetics to Resolve Challenging Problems Involving Endangered Species

  Southern Adventist University

  Amphipod crustaceans comprising the Gammarus pecos species complex are endemic along the Pecos River of New Mexico and Texas. At least one entity in this complex is a federally listed endangered species, but identification and monitoring of these amphipods present some challenges due to their cryptic morphology. Data from Richard’s ongoing PhD research dealing with sequencing of the cytochrome oxidase I and 16S rRNA genes will likely merit separate species description and consideration for state and/or federal protection.

  Arthur Chadwick - Breakthrough Science and the Creation Worldview: Grand Canyon as a Test Case

  Southern Adventist University

  In the Grand Canyon, the first layer deposited above the eroded Precambrian surface and the first layer containing undoubted metazoan fossils is the Cambrian Tapeats Sandstone. It is proposed that the Tapeats Sandstone was deposited in deep water in connection with tectonic (earth movement) processes and the associated collapse of a submarine shelf farther to the east.

  Brian Dickinson - Zoonosis: Cutaneous Larval Migrans, Creeping Eruptions, Diarrhea...Gotta Love It

  Southern Adventist University

  Human-animal diseases are a major health concern even today. This lecture goes over some of the more common diseases that we can contract from our four-legged companions.

• 

  Carl Person - The "Guarico" Rattlesnake (Crotalus durissus "pifanorum"): Subspecies or Not?

  Southern Adventist University

  The genetic basis within the geographic variations for C. durissus clade was determined, and the taxonomic implications for subspecies determinations will be discussed.

• 

  Dottie Shuman - What is Your Role in Creation Care?

  Southern Adventist University

  You will be encouraged to explore the role that God has for Christians in caring for His creation. In this presentation you will be introduced to the different perspectives that Christians have in caring for God’s creation and learn about one person’s journey toward that goal. Come and be challenged to find the role that God has for you.

  John Wood - Bamboo: The Miracle Grass

  Southern Adventist University

  Bamboo is a renewable source of plant fiber that can be used for paper pulp, engineered wood products, biomass fuel, and food. West Wind Technology’s vision is to introduce the use of bamboo to Western countries as a viable substitute for wood.

  Margeret Kovac - Molecular Pathology of Deafness and Cancer: Models for Understanding Regulation of Gene Expression

  Southern Adventist University

  Differential patterns of gene expression, genomic instability and DNA methylation are used to examine typical and athypical mechanisms of controlled gene expression in development of the ear and colon cancer.

  Paul Buchheim - Paleoecology and Paleoenvironments of the Eocene Green River Lake System

  Southern Adventist University

  The Eocene Green River Lake System (Green River Formation) portrays a variety of ecological and paleoenvironmental settings. We have reconstructed physical, chemical, and biological aspects of these lakes, and have mapped the extent and location of cyanobacterial reefs. Using "forensic" studies we have been able to reconstruct a fairly accurate picture of the details of these amazing lake systems.

  Sabrina Novak - Current and Historic Freshwater Mollusk Distributions of the upper Coosa River Basin

  Southern Adventist University

  The Tennessee Aquarium Research Institute (TNARI) surveyed freshwater mollusks within the Upper Coosa River Basin (UCRB) from 1998 to 2003. Survey activities for these studies occurred primarily in Georgia, but also in Tennessee and Alabama. Qualitative sampling of freshwater mollusks was completed by wading and/or snorkeling for generally 30-60 minutes per site. In addition to original survey data collected, a large historical database was constructed from natural history museum records to evaluate changes in species richness and distribution over time across the UCRB.
