Abstract Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized embryo-masses. These observations raise the possibility that individuals may have been fertilized by waterborne sperm, a possibility that has never been seriously considered in barnacles. Using molecular tools (Single Nucleotide Polymorphisms; SNP), I examined spermcast mating in P. polymerus and B. glandula as well as Chthamalus dalli (which is reported to self-fertilize) in Barkley Sound, British Columbia, Canada. -

ZOOBANK http://zoobank.org/urn:lsid:zoobank.org:pub:74B93F4F-0E5E-4D69- A7F5-5F423DA3762E ABSTRACT A large number of specimens (2765) of the acorn barnacle Balanus trigonus Darwin, 1854, were observed on the spiny lobster Panulirus gracilis Streets, 1871, in western Mexico, including recently settled cypris (1019 individuals or 37%) and encrusted specimens (1746) of different sizes: <1.99 mm, 88%; 1.99 to 2.82 mm, 8%; >2.82 mm, 4%). Cypris settled predominantly on the carapace (67%), mostly on the gastric area (40%), on the left or right orbital areas (35%), on the head appendages, and on the pereiopods 1–3. Encrusting individuals were mostly small (84%); medium-sized specimens accounted for 11% and large for 5%. On the cephalothorax, most were observed in branchial (661) and orbital areas (240). Only 40–41 individuals were found on gastric and cardiac areas. Some individuals (246), mostly small (95%), were observed on the dorsal portion of somites. -
The Role of Avian Predators in an Oregon Rocky Intertidal Community
AN ABSTRACT OF THE THESIS OF Christopher Marsh for the degree of Doctor of Philosophy in Zoology presented on May 24, 1983 Title: The Role of Avian Predators in an Oregon Rocky Intertidal Community Abstract approved: Redacted for Privacy Dr. Bruce-Nenge Birds affected the community structure of an Oregon rocky shore by preying upon mussels (Mytilus spp.) and limpets (Collisella spp.).The impact of such predation is potentially great, as mussels are the competitively dominant mid-intertidal space-occupiers, and limpets are important herbivores in this community. Prey selection by birds reflects differences in bill morphology and foraging tactics. For example, Surfbird (Aphriza virgata) uses its stout bill to tug upright, firmly attached prey (e.g. mussels and gooseneck barnacles [Pollicipes polymerus]) from the substrate. The Black Turnstone (Arenaria melanocephala), with its chisel-shaped bill, uses a hammering tactic to eat firmly attached prey that are 1) compressed in shape and can be dislodged, or 2) have protective shells that can be broken by a turnstone bill. In addition, the Black Turnstone employs a push behavior to feed in clumps of algae containing mobile arthropods. Bird exclusion cages tested the effects of bird predation on 1) rates of mussel recolonization in patches (50 x 50 cm clearings), and 2) densities of small-sized limpets (< 10 mm in length) on upper intertidal mudstone benches. Four of six exclusion experiments showed that birds had a significant effect on mussel recruitment. These experiments suggested that the impact of avian predators had a significant effect on mussel densities when 1) the substrate was relatively smooth,2) other mortality agents were insignificant, and 3) mussels were of intermediate size (11-30 mm long). -

Frank The opisthobranch molluscs of Oregon have been little studied, and little is known about the biology of many species. The present study consisted of field and laboratory observations of Cape Arago opistho- branchs. Forty-six species were found, extending the range of six north- ward and two southward. New food records are presented for nine species; an additional 20 species were observed feeding on previously recorded prey. Development data are given for 21 species. Twenty produce plank- totrophic larvae, and Doto amyra produces lecithotrophic larvae, the first such example known from Eastern Pacific opisthobranchs. Hallaxa chani appears to be the first eudoridacean nudibranch known to have a subannual life cycle. Development, life cycles, food and competition, iv ranges, and the ecological role of nudibranchs are discussed. Nudi- branchs appear to significantly affect the diversity of the Cape Arago encrusting community. -

They are ubiquitous on the Oregon coastline and grow in dense aggregation in the intertidal zone. Reproductive biology of the species makes them particularly susceptible to overfishing, and in the interest of sustainability, aquaculture was explored as one option to supply a commercial product without impacting local ecological communities. A novel aquaculture system was developed and tested that caters to the unique feeding behavior of Pollicipes polymerus. -

Impacts of the Pisaster Ochraceus Collapse on Intertidal Communities an Honors Thesis Submit
Changing Communities: Impacts of the Pisaster ochraceus Collapse on Intertidal Communities An Honors Thesis Submitted to the Department of Biology in partial fulfillment of the Honors Program STANFORD UNIVERSITY by Roberto Guzman November 2015 Acknowledgments I’d like to thank Terry Root and the Woods Institute for their MUIR Grant that made this all possible. And also for teaching me on the importance of an interdisciplinary education. I’d also like to thank my advisor, Fiorenza Micheli, for her assistance, expertise, patience, and ideas that helped throughout this project, every step of the way. Whether it was helping with setting up the projects, analyzing the results with me, or just coming out to the intertidal zone with me to help with field work, without you, this project and my thesis would not exist. Thank you Mark Denny for your contribution to my thesis. I appreciate not only your help as a second reader, but as someone who was able to contribute fresh eyes to my thesis, providing me with valuable insight of things I may have missed after working on the thesis. I am also grateful for the assistance of James Watanabe. Whether it was his expertise in the biology of the intertidal zone, or his quadrat camera setup, the success of the project lends itself to his efforts and generosity. A lot of appreciation goes to Steve Palumbi for providing me with financial assistance this year. You have not only helped me with it, but also my family. Your generosity will not be forgotten. For assisting me in fieldwork and making it more enjoyable, I’d like to thank Gracie Singer. -
Intertidal Zonation Does Species Diversity Decrease with Tidal Height?
Intertidal Zonation Does Species Diversity Decrease with Tidal Height? Biology 4741574 Summer 2004 Student Report by Wendy Cecil, Kate Olsen, Susan Shrimpton, Laura Wimpee Jonathan ~eischner, Matthew Osborne-Koch, Sylvia Yamada and Alicia Helms, Instructors - Perhaps no other community has captured the attention of field ecologists like the rocky intertidal zone. This fascinating transition zone between land and sea allows ecologists to study patterns of species distributions, abundance and diversity. The most striking observation one makes when visiting a rocky seashore is that organisms are distributed in horizontal bands. From the low to the high tide mark one can readily identifl zones dominated by the brown kelp Laminara, pink encrusting coralline algae, dark blue mussel beds, white barnacles, littorine snails, and finally black lichens (Figure 1). Linoflna/Pelvetia/Chrhamalusbelt Figure 1. Typical Pattern of intertidal zonation of organisms. Intertidal zonation, just like altitudinal and latitudinal zonation, is a reflection of organisms' responses to physical gradients and biological interactions (Merriam 1894, Whitta.ker 1975). Intertidal zonation is unique in that the physical gradients are very steep (e.g. a 12 ft. tidal range versus hundreds of miles in latitudinal zonation). Organisms living in the low tidal zone spend over 80% of their time in the benign and constant marine environment, while the reverse is true for organisms living in the high zone (Figure 2). At Mean Sea Level organisms spend equal amounts of time being immersed in seawater and exposed to air. Since intertidal organisms (with some exception such as mites and insects) originated in the sea, species diversity decreases up the shore.
