  1. BIO 354 Marine Invertebrate Evolution Virginia Wesleyan College Dr. Gonsalves-Jackson

  2. BIO 354: Marine Invertebrate Evolution Private, liberal arts undergraduate college 1400 FTE Upper level course for Biology Majors (B.S./B.A.) Integrative and Evolutionary Biology concentration 4 credits (lecture/lab) Prerequisite: 1 semester Introductory Biology Fall 2010 10 students Second offering Fall 2011

  3. Course Description Course Description: This course is an introduction to the study of evolutionary processes. We examine the basic mechanisms for evolution with particular attention paid to marine invertebrates, especially marine bivalves, as they have a rich evolutionary history and a well-documented fossil record. Evolution will be examined at a variety of scales from molecular to ecological. Course Goals: Upon completion of the course students should be able to describe: 1. What evolution is and the evidence from marine invertebrates that support it 2. The major mechanisms of evolution 3. How scientists study evolution 4. How evolution is relevant to our lives

  4. Intellectual Demands on Students Lecture Component 3 exams Primary research article review paper Oral presentation 67% of grade Laboratory Component • Practical exam • Laboratory Notebook • 33% of grade

  5. Lecture and Laboratory Schedule Fall 2010

  6. BIO 354 Marine Invertebrate EvolutionLaboratory Bivalve Evolution: Diversity of Form and Function Student shell collection of 13 species LAB OBJECTIVES: To examine shell anatomy and be able to identify key morphological features To examine bivalve diversity as it relates to form To be able to relate shell morphology/diversity with function and habitat Representative species: Tridacnacrocea Mercenaria mercenaria Tellina sp. Spondylus spp. Chama sp. Arca zebra Crassostrea virginica Pectenspp. *Arctica *Margaritifera sp. *Driesseniapolymorpha *Corbicula sp. *Teredo or Martesia sp. *Gemma/ Parastarte *Nucula

  7. BIO 354 Marine Invertebrate EvolutionLaboratory Bivalve Species Richness, Diversity and Size class distribution First Landing State Park beach habitat LAB OBJECTIVES: To survey bivalve species within the beach habitat of First Landing State Park To identify species collected and calculate species richness and abundance To create a size class distribution for collected species To calculate species diversity (evenness)

  8. BIO 354 Marine Invertebrate EvolutionLaboratory Bivalve Anatomy- Dissection of Representative Species Mercenaria mercenaria Mytilus edulis LAB OBJECTIVES: To examine shell anatomy and be able to identify key morphological features To examine internal anatomy and be able to identify key morphological features

  9. BIO 354 Marine Invertebrate EvolutionLaboratory Life History and Oyster Reef Restoration Chesapeake Bay Foundation and VIMS Crassostreavirginica LAB OBJECTIVES: To understand the life history of Crassostreavirginica To understand the state of oyster reefs in the Chesapeake Bay and Lafayette River To participate in oyster reef restoration efforts

  10. BIO 354 Marine Invertebrate EvolutionLaboratory Physiology and Feeding Mytilus edulis Mercenaria mercenaria Crassostrea virginica LAB OBJECTIVES: To examine the effect of water temperature on the heart rate of Mytilus edulis To observe ciliary feeding in M. edulis and M. mercenaria To isolate and grow coliform bacteria from M. edulis, M. mercenaria and C. virginica

  11. BIO 354 Marine Invertebrate EvolutionLaboratory Cladistics Bivalve shell collection LAB OBJECTIVES: To code multiple characters of bivalve species To create a data matrix of character and character states of bivalve species To create a cladogram of bivalve species
