Hydrodynamic Regulation Of Reproduction In Fucoid Algae: A Regional Model And Consequences For Population Structure, Susan H. Brawley
Hydrodynamic Regulation Of Reproduction In Fucoid Algae: A Regional Model And Consequences For Population Structure, Susan H. Brawley
University of Maine Office of Research Administration: Grant Reports
Fucoid algae dominate most rocky shores across the north Atlantic and contribute substantially to structuring of the coastal ecosystem. Reproduction in fucoid algae is sensitive to hydrodynamic conditions, resulting in high fertilization success because gamete release occurs only under calm conditions. These findings have important implications for asynchrony in gamete release between populations and the scale of population isolation. This study will 1) test a nascent model describing when successful fucoid reproduction can occur, 2) determine whether hybridization between Fucus vesiculosus and other fucoid algae occurs when gamete release is delayed by turbulent conditions, and 3) analyze whether genetic differentiation …

Collaborative Research: Functional And Genomic Analysis Of Polysymbiosis In The Wood-Boring Bivalve Lyrodus Pedicellatus, Daniel L. Distel

Each day massive quantities of wood and woody plant materials enter the oceans, providing resources upon which a large variety of marine organisms depend. However, the biological communities supported by marine wood are only poorly understood. Globally, the most important consumers of marine wood are wood-boring bivalves of the family Teredinidae (shipworms, primarily found above 150 m) and Pholadidae (subfamily Xylophagainae, primarily found in the deep sea, 150-8000 m). These clams depend on intracellular endosymbiotic bacteria (endocytobionts) to help them consume a substrate (lignocellulose) that cannot be utilized by most other animals. Two functions have been proposed for symbionts of …
