Isa Woo Elizabeth Brusati 2015 <p>This case study includes representative macroinvertebrates that live in the marsh plain, its associated channels and pannes (ponds), and the marsh-upland transition zone. While less visible than animals such as birds, invertebrates play important roles in physical and biological processes (e.g., burrowing activity and channel bank erosion, and detritivores breaking down organic matter) and are important food resources for higher trophic animals. Common invertebrates in these habitats include plant-hopper (<i>Prokelisia marginata</i>), beach hopper (<i>Traskorchestia traskiana</i>), pygmy blue butterfly (<i>Brephidium exilis</i>), inchworm moth (<i>Perizoma custodiata</i>), western tanarthus beetle (<i>Tanarthus occidentalis</i>), salt marsh mosquitoes (<i>Aedes</i> spp.; Maffei 2000a, Maffei 2000b, Maffei 2000c), crabs (native <i>Hemigrapsus oregonensis</i> and introduced <i>Carcinus maenas</i>), copepods, snails (e.g. native California horn snail <i>Cerithidea californica</i> and introduced <i>Ilyanassa obsoleta</i>, <i>Myosotella myosotis</i>), polychaetes (e.g. <i>Capitella</i> spp., <i>Eteone californica</i>, <i>Neanthes brandti</i>), small clams (<i>Macoma petalum</i>/<i>M. balthica</i>), and corophiid amphipods (Cohen 2011, Race 1982, Robinson et al. 2011). Some common species were described in detail in the San Francisco Bay Goals Project Species and Community Profiles (Goals Project 2000). </p> application/pdf en California State Coastal Conservancy Science foundation Chapter 5 Appendix 5.1: Case study marsh macroinvertebrates reports
