<p> Marine Biology Slide Show, Demonstration and Seashore Trip given by Dr. Bill Crowe, School of Science IT Sligo.</p><p>Typical Marine Biology Talk Outline</p><p>1. Introduction to waves, swell and fetch (using ropes) and their influence on shore wave exposure and biodiversity; the “Goldilocks Principle, where conditions are just right”. Introduction to tides (using balls a hoop and fancy dress to demonstrate the effect of sun and moon on water movements), and to show their effect on rocky seashore zonation. Physical and Biological reasons for zonation of lichens, algae and fauna. http://staffweb.itsligo.ie/staff/bcrowe/bill/styles/frames/marbiol/sshorero/sshorerl.htm Introduction to the major algal and animal groups: Beautiful Slides and demonstration, under microscopes, of live barnacles feeding; living, dead and fossil corals, anemones, and jellyfish; mollusc shells and crustaceans; Singing Fish.</p><p>2. Sampling Methods: from shore to deep sea for many types of species; methods for collection of larval stages: Powerpoint slide show http://staffweb.itsligo.ie/staff/bcrowe/bill/marhome.htm and demonstrations of gear; and scuba diving equipment. </p><p>3. Alcohol preserved real specimens of odd looking Deep Sea Fish and Invertebrates (from 3 miles down) “ Rat tailed sharks: small monsters of the deep! ”. Short video clips of Whales and Dolphins. Humans and dolphins blowing bubbles under water. Video of Salps http://staffweb.itsligo.ie/staff//bcrowe/bill/chalt.htm http://staffweb.itsligo.ie/staff/bcrowe/bill/photos/jpgscssc/cnatmus.htm http://staffweb.itsligo.ie/staff//bcrowe/bill/CTYIMarBiolStu2013.htm</p><p>4. Systematic approach to naming and describing the biology of shore and sub-littoral marine lichens, algae and animal phyla: Powerpoint demonstrations and living specimens in tanks and trays. Mainly algae, and lower invertebrates (protostomes) http://www.seaweed.ie/ (by Dr. Michael Guiry) </p><p> http://www.seaweed.ie/sargassum (by Dr. Michael Guiry) with information on Sargassum seaweed ; recent sightings in Ireland and a Sighting questionnaire for Ireland. </p><p> http://www.habitas.org.uk/marinelife/ look at sections on brown, green and red algae</p><p>Continuation of Systematic approach to naming and describing the biology of shore and under water marine lichens, algae and animal phyla: Powerpoint demonstrations, slide shows, and web demonstrations, together with observations on living specimens in tanks and trays, and under microscopes. Mainly higher invertebrates (deuterostomes) and vertebrates (e.g. fish). http://staffweb.itsligo.ie/staff/bcrowe/bill/styles/frames/taxon/kingd/5kingdho.htm</p><p>Systematic approach to Whale and Dolphin sightings and identification. </p><p> http://staffweb.itsligo.ie/staff/bcrowe/bill/styles/frames/taxon/kingd/ankingd/chord/vert/dolph&wh.htm</p><p>5. For Sligo Schools</p><p>Introduction to Raughly Beach: algal and Faunal zonation and photos and videos of Fin Whales stranded at Raughley http://www.sligotoday.ie/details.php?id=17751&PHPSESSID=e66ee667edfdc2f6ebc295f153c92e61</p><p>Field trip to Raughly rocky beach to study ecology and zonation of marine algae and animal species; collection of some species for observation back at school, in trays and using some microscopes brought by Bill. </p><p>Geomorphology of the region, and of the blow hole nearby, may be found in the Geomorphology section, on Dr. Don Cotton's Natural History of Sligo and Leitrim web Site: http://staffweb.itsligo.ie/staff/dcotton/Geomorphology.html More photos of the area Facebook Bill Crowe Photos of recent course at this site: http://staffweb.itsligo.ie/staff/bcrowe/bill/styles/frames/marbiol/sshorero/DCUGifChildRaughley/DCURaughley.htm</p><p>Post Trip to School Quiz.</p>
