The Marine Bryozoa Near the Panama Canal
Abstract:The diversity of Bryozoa at the Pacific entrance to the Panama Canal is threefold that at the Atlantic. Three ecological components are recognized on the Pacific side, two on the Atlantic. Since its inception 56 years ago, successful transmigrations of Bryozoa through the Canal have been unidirectional, as demonstrated by the occurrence of three Atlantic fouling species at the Pacific entrance, i.e., Membranipora annae Osburn, Electra monostachys (Busk) and Bugula stolonifera Ryland. Gemelliporidra multilamellosa (Canu & Bassler) and Trematooecia aviculifera (Canu & Bassler), both previously known as fossils from the Upper Tertiary of Panama, have persisted into the Recent Panamic-Atlantic intertidal environment.
