I am very grateful for the endless opportunities that she has provided and her willingness to help me through any obstacle. She has enabled me to see my full potential and encouraged me to never give up. Besides her assistance and leadership as a supervisor, I am fortunate to have gained such a wonderful friend in the process. Her charisma and enthusiasm has made my graduate experience unforgettable and am thankful for all her advice, knowledge and wonderful memories that I will cherish forever. I would further like to extend my gratitude to the members of my committee for all their support and comments during this process. I would like to specifically thank Dr. Kathy Foltz for her willingness to read any thing I threw at her and for a great number of coffee talks, Dr. Steve Gaines for his help with statistics and editing, and Dr. Bruce Menge for his expertise in intertidal ecology and eagerness to help anytime. Without these fantastic committee members the completion of this dissertation would not have been possible. I am very appreciative of all the field assistance I have had over the years. The completion of field work would have not been successful without the help from Dr. Gretchen Hofmann, Tim Crombie, Jessie Dutton, Dr. Sarah Henkel, Elizabeth Hoaglund, Paul Matson, Dr. Chris Osovitz, and Dr. Sean Place. I would especially like to thank Drs. Anne Todgham and Nann Fangue for their guidance in the molecular analysis, assistance with the CO2 system, great scientific chats, iv helping me with the late night experiments, and for taking care of me with wonderful cooking. In addition, I would like to thank Benjamin Beede for his generosity in supplying abalone larvae and his assistance with culturing the larvae. I would also like to acknowledge Drs. Herb Waite, Ali Miserez, Amy Moran, Mary Sewell and Richard Strathmann for their contributions. Dr. Waite provided access to critical equipment used in this dissertation and Dr. Ali Miserez kindly devoted his time to helping me with the development and analysis of the nanoindentation measurements. Drs. Amy Moran, Mary Sewell and Richard Strathmann provided important input and suggestions regarding the biology of invertebrate larval development. Finally I wish to acknowledge the love and support from my family on this journey. My parents, Steve and Pam Zippay, have encouraged my passion for marine science ever since I was young and have taught me to pursue my dreams. Finally, to my husband, Sean Place, whose confidence in me has helped to carry me through this experience. Thank you for all your love and support. These studies were funded by University of California Marine Council under the Coastal Environmental Quality Initiative (CEQI) Graduate Student Fellowship program and the Mildred E. Mathias Graduate Student Research Grant from the University of California Natural Reserve System. Partial support has also come from an Alan J. Kohn Graduate Student Fellowship from Friday Harbor Laboratories at the University of Washington. Additional funds were obtained from the Partnership for Interdisciplinary Studies of Coastal Oceans, funded by the Packard and Moore Foundations. I am also thankful for financial support from UC Santa Barbara in the v form of the Broida-Hirschfelder Fellowship, Science and Engineering fellowship and Nancy Brown Environmental Graduate Dissertation Award. vi VITA OF MACKENZIE L.

  • Structure and Function of the Digestive System in Molluscs
    Cell and Tissue Research (2019) 377:475–503 https://doi.org/10.1007/s00441-019-03085-9 REVIEW Structure and function of the digestive system in molluscs Alexandre Lobo-da-Cunha1,2 Received: 21 February 2019 /Accepted: 26 July 2019 /Published online: 2 September 2019 # Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract The phylum Mollusca is one of the largest and more diversified among metazoan phyla, comprising many thousand species living in ocean, freshwater and terrestrial ecosystems. Mollusc-feeding biology is highly diverse, including omnivorous grazers, herbivores, carnivorous scavengers and predators, and even some parasitic species. Consequently, their digestive system presents many adaptive variations. The digestive tract starting in the mouth consists of the buccal cavity, oesophagus, stomach and intestine ending in the anus. Several types of glands are associated, namely, oral and salivary glands, oesophageal glands, digestive gland and, in some cases, anal glands. The digestive gland is the largest and more important for digestion and nutrient absorption. The digestive system of each of the eight extant molluscan classes is reviewed, highlighting the most recent data available on histological, ultrastructural and functional aspects of tissues and cells involved in nutrient absorption, intracellular and extracellular digestion, with emphasis on glandular tissues. Keywords Digestive tract . Digestive gland . Salivary glands . Mollusca . Ultrastructure Introduction and visceral mass. The visceral mass is dorsally covered by the mantle tissues that frequently extend outwards to create a The phylum Mollusca is considered the second largest among flap around the body forming a space in between known as metazoans, surpassed only by the arthropods in a number of pallial or mantle cavity.
