Giant Green Anemones Consume Seabird Nestlings on the Oregon Coast
Sheffield Guy et al.: AnemonesContributed consume Papers seabird nestlings in Oregon 1 GIANT GREEN ANEMONES CONSUME SEABIRD NESTLINGS ON THE OREGON COAST LISA SHEFFIELD GUY1, LISA BULLIS HABECKER2 & GRETEL OXWANG3 1University of Washington/Joint Institute for the Study of the Atmosphere and Ocean, NOAA/PMEL Building 3, Sand Point Way NE, Seattle, WA 98115, USA ([email protected]) 2City of Cannon Beach, Haystack Rock Awareness Program, PO Box 368, Cannon Beach, OR 97110, USA 3US Fish and Wildlife Service, Oregon Coast NWR Complex, 2127 SE Marine Science Drive, Newport, OR 97365, USA Submitted 13 September 2013; accepted 26 September 2013 It is uncommon for marine invertebrates to prey on seabirds, with penicillatus cormorants nest in small numbers on this rock and other octopi being the exception (e.g. Sazima & Bastos de Almeida sea stacks in the immediate vicinity. The Giant Green Anemone is 2008, CBC News 2013). We report here a Giant Green Anemone a widely distributed and common intertidal invertebrate in this Anthopleura xanthogrammica consuming a nestling cormorant area. Its typical prey includes small fish, crustaceans and detached Phalacrocorax sp., observed in the rocky intertidal zone at the mussels, which are stung and immobilized using nematocysts in the base of Haystack Rock in Cannon Beach, Oregon, on 24 July 2013 tentacles and then consumed (Dayton 1973). (Fig. 1), as well as less detailed observations involving gull Larus spp. nestlings (see below). Pelagic P. pelagicus and Brandt’s P. It is unknown whether the chick was alive or dead when engulfed by the anemone. It is possible that a predator such as a Bald Eagle Haliaeetus leucocephalus dropped this chick or that it was knocked from the nest during a disturbance event. -
Starfish Adaptations: Peer-Taught
Starfish Adaptations: Peer-Taught Subject (Focus/Topic): Life Science: Animal adaptations, structure and function, habitat, natural selection. Grade Level: Second Grade; taught by high school biology students. Average Learning Time: This lesson will take approximately two 45-minute periods. Lesson Summary (Overview/Purpose): Students will observe, explore, dissect and compare members of the animal phylum Image credit: Divegallery.com Echinodermata to understand what particular traits make them successful in their environment. Second grade students work with peer (high school student) teachers. Overall Concept (Big Idea/Essential Question): Students explore an unknown organism to understand that every living creature has traits that impact their use of habitat. The structure and function of traits are important in an individual’s survival and the survival of populations. Specific Concepts (Key Concepts): Students will understand three key features of starfish systems: water vascular, digestive and integument (skin). They will compare these systems to human and describe ways that the starfish systems are beneficial to them in their environment. Students will relate the success of starfish to their adaptations. Focus Questions (Specific Questions): Where do starfish live? What is their habitat? If you lived in the ocean, what would you need to survive? What do you notice about the starfish’s skin? How might the starfish skin help it in its habitat? What do starfish use to move? How do they do this? Do starfish need oxygen like humans do? How do they get their oxygen? How do starfish get food? What do they use to get food? How do starfish see? Where do you think their eyes are located? Objectives/Learning Goals: Students will be able to describe three structures of starfish anatomy and relate the structure to function with 80% accuracy. -

The recent sea star die-off throughout the eastern Pacific, known as Sea Star Wasting Disease, has prompted a need to understand spatial and temporal patterns of seastarassemblages and the environmental variables that structure these assemblages. We examined spatial and temporal patterns in sea star assemblages (composition and density) across regions in the northern Gulf of Alaska and assessed the role of seven static environmental variables (distance to freshwater inputs, tidewater glacial presence, exposure to wave action, fetch, beach slope, substrate composition, and tidal range) in influencing sea star assemblage structure before and after sea star declines. -

Stephensen U.S. Fish and Wildlife Service Oregon Coast National Wildlife Refuge Complex 2127 SE Marine Science Drive Newport, Oregon 97365 January 2014 Cite as: Stephensen, S.W. 2014. Tufted Puffin monitoring study at Haystack Rock, Cannon Beach, Oregon 2010-2013. U.S. Fish and Wildlife Service Unpublished Report, Oregon Coast National Wildlife Refuge Complex, Newport, Oregon 97365. 16 pp. EXECUTIVE SUMMARY The Tufted Puffin (Fratercula cirrhata) is a medium-large pelagic seabird and member of the Auk family. The distribution of the Tufted Puffin is widespread in the North Pacific Ocean and nests on the coastline and offshore islands in California, Oregon, Washington, British Columbia, Alaska, Japan, and Russia. Tufted Puffin populations have generally declined throughout the southern portion of their range from British Columbia to northern California. Possible causes of puffin decline include factors related to conditions at breeding sites, at-sea mortality due to direct human impacts, and long-term changes in marine food webs. The U. S. Fish and Wildlife Service conducted a burrow-nesting seabird survey that encompassed the entire coastline of Oregon in 2008 and documented an order of magnitude decline in the puffin population since the previous official statewide survey in 1988. The purpose of this project was to conduct an intensive population status assessment of the Tufted Puffin at Haystack Rock (colony number 219-021), which is part of the Oregon Islands National Wildlife Refuge. Haystack Rock is a 72 meter tall sea stack, located on the north coast of Oregon at Cannon Beach. -
Recreational Divers of Oregon Proposal for Kelp Forest Preservation in Rocky Subtidal Zones of the Oregon Coast
Initial Proposal Period Oregon Rocky Habitat Management Strategy FORMAL LETTER to O.P.A.C. Recreational Divers of Oregon Proposal for Kelp Forest Preservation in Rocky Subtidal Zones of the Oregon Coast @NBCNEWS: “With a loss of kelp forests, you're going to have a very, very profound impact on an ecosystem,” said Tristin McHugh, Reef Check California’s North coast regional manager. “It's like losing your redwoods. What would happen if you saw 90 percent of your redwoods drop dead right now?” For McHugh and many others, the biggest problem is awareness. Most people don’t even realize what sort of a catastrophe is happening below the sea surface. “This is the fight of our generation,” she said. “If we can't set ourselves up right now, there's going to be nothing for our kids further down the line." Initial Proposal Period Purple sea urchins predating the last kelp on this reef- completing an ‘urchin barren’ Special Note: In case the matching Proposal submitted 12/31/20 on the SeaSketch website may not meet some Rocky Shores’ Proposal screening criteria, (the ideas herein are really meant for most of the subtidal sites of the Oregon Coast) - we are also submitting this via email as a FORMAL LETTER to OPAC and the Rocky Shores Working Group. Pg. 37 Oregon Territorial Sea Plan: Part Three “Where the desired outcome cannot be met with a site designation proposal, members of the public and interested entities should outline their concern or desired regulatory change in a formal letter to the Ocean Policy Advisory Council.” Contact Information Please fill out the following section with primary contact information for this proposal. -

Populations of the sunflower sea star were also devastated. Why is this important? The sunflower sea star is the only real predator for the Purple sea urchin other than humans. It is almost like one of those ‘z’ science fiction movies. There’s a monster with no head, wiping out precious resources, that seemingly lives forever, and eats its own kind. It could have been a story about the Purple sea urchin. Where found 1/4 The Purple sea urchin lives on the Pacific coastline and is found from Alaska to Cedros Island, Mexico. -

Lab Program Curriculum Grades 1-3
Lab Program Curriculum Grades 1-3 2 Program Description This 45-60 minute lab program introduces students to four intertidal animals and their adaptations for feeding, motion, protection and sight. During this program your students will hear a brief introduction to tidepools and adaptations and then travel to four stations to study some invertebrates that live in tidepools. Students will then have an opportunity to touch the animal at their station. After this program your students will understand the difference between a vertebrate and an invertebrate and be familiar with four invertebrates found along the Oregon coast. They will also learn how to handle ocean animals carefully and understand some similarities and differences between themselves and animals of the sea. Participating in this program will help your student to meet the grade three common curriculum goals and benchmarks listed on the back of this sheet. Chaperones will be asked to take an active role in the lab program, which is designed so that they read informational cards in English to the students in their group. It will also be the chaperone’s responsibility to monitor the students’ behavior during the lab program. Before your visit: • Using pictures from magazines or drawings make ocean plant and animal cards. Use these and the enclosed animal flash cards to familiarize students with organisms they may see at the Aquarium. Incorporate appropriate vocabulary, Rockfish play concentration or use them as flash cards for plant and animal identification. • Have your students make a Flashcard Notebook using the flashcards provided. They can take this on their field trip to help identify animals at the Aquarium. -
