Backstory: Interactions and Mechanisms Backstory: Upogebia is a high biomass ecosystem engineer that reworks and remineralizes estuary sediments (DeWitt et al. 2004, D’Andrea and DeWitt 2009) Bopryid Isopod parasites infest decapod crustaceans and effectively castrate their female hosts Markham (2004) described Orthione griffenis, collected from the intertidal estuary mud shrimp, Upogebia pugettensis of Yaquina Bay OR in 2002 Orthione was introduced to North America from Asia in the 1980s (Chapman et al. 2012) Orthione is associated with severe declines of Upogebia over its entire range (Chapman 2012, Dumbauld et al. 2011). Interactions and mechanisms: Variable host condition and possible vulnerability - Orthione restricted to reproductive sized Upogebia Highest prevalence among Upogebia females No relation between parasite load and host weight loss (Smith et al. 2008, Dumbauld et al. 2011, Griffen 2009, Repetto and Griffen 2012) Could Orthione prevalence among Upogebia females result from sex change or greater male mortality? (Griffen 2009, Repetto and Griffen 2011) Asson A relation between energetics and parasite load? (Repetto and Griffen 2011) Burton Could trophic conditions for hosts control host vulnerability? ~Young Can an ecosystem engineer of Oregon estuaries, the blue mud shrimp, be spared from extinction?

    Zootaxa 1344: 33–41 (2006) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA 1344 Copyright © 2006 Magnolia Press ISSN 1175-5334 (online edition) Systematics of the genus Scleroplax Rathbun, 1893 (Crustacea: Brachyura: Pinnotheridae) ERNESTO CAMPOS Facultad de Ciencias, Universidad Autónoma de Baja California, Apartado Postal 2300, Ensenada, Baja California, 22800 México. E-mail: [email protected]; [email protected] Abstract The taxonomic status of the monotypic genus Scleroplax Rathbun, 1893, is evaluated and separated from other genera of the Pinnixa White, 1846, complex. Distinguishing characters of Scleroplax are a hard, subheptagonal and dorsally, highly convex carapace, and a third maxilliped with a propodus that extends to the end of the dactylus. The genera Scleroplax, Pinnixa, Austinixa Heard & Manning, 1997, Glassella Campos & Wicksten, 1997, Indopinnixa Manning & Morton, 1987, and Tetrias Rathbun, 1898, share a carapace than is wider than long and a distinct lateral exopod lobe on the third maxilliped, all of which may represent monophyletic characters. Updated information on the distribution and hosts of S. granulata Rathbun, 1893, indicate that the species now ranges from Vancouver Island, British Columbia, Canada to El Coyote estuary, Punta Abreojos, Baja California Sur, México. It inhabits burrows of the echiuroid Urechis caupo Fisher & MacGinitie, 1928, and the mud shrimps Neotrypaea californiensis (Dana, 1854), N. gigas (Dana, 1852) (new host record), Upogebia pugettensis (Dana, 1852), and occasionally U. macginiteorum Williams, 1986 (new host record). Key words: Crustacea, Brachyura, Pinnotheridae, Scleroplax, systematics, geographic distribution, new hosts Resumen El estatus taxonómico del género monotípico Scleroplax Rathbun, 1893, es evaluado y separado de otros géneros del complejo Pinnixa White, 1846.

However, expected host weight losses with increasing parasite weights do not occur, even among apparently castrated females. The prevailing assumption that energetic losses cause host castration have thus remained open to question, and the mechanism(s) resulting in castration and consequent population declines of U. pugettensis have remained unclear. Proposed alternative explanations for these declines, which have been based on a dramatically greater prevalence of O.

  • 3 Mini-Ecosystem Or Seafood Smorgasbord? for Website
    Mini-ecosystem or Seafood Smorgasbord? by Linda Schroeder, photos by Greg Jensen This is how Greg Jensen phrased it in his email when he sent me the photo of this Blue mud shrimp, Upogebia pugettensis, found during a May survey on the east side of Indian Island. The survey is part of preparations to remove the man-made connection between Indian and Marrowstone Islands, restoring the water channel. There were several notable features of this mud shrimp. First, it was sitting out of its burrow at low tide, “waiting to be eaten by a seagull” said Greg. Secondly, he noted the pea crab, Scleroplax granulata, remained clinging to the shrimp. While it is a known associate of the shrimp, living in its burrows, it seemed more unusual that it hadn’t remained in the burrow and instead stayed with the shrimp as it left the safety of the burrow. It was actually clinging to the Mud shrimp clam as much as the shrimp. This clam, Neaeromya rugifera, is well- known to live commensally on the abdomen of the mud shrimp. The final notable feature was the presence of the parasitic isopod, Orthione griffenis. This is an invasive Asian species first discovered in Washington in 1988. The isopod appears to be causing the collapse of mud shrimp populations along the Pacific coast. It prevents the female shrimp from being able to reproduce and in some places more than 90% of the mud shrimps are infected. This shrimp harbored quite the little ecosystem going on with both commensal and parasitic relationships. It was also a seafood smorgasbord featuring three crustacean species and a mollusk for some happy gull if Greg hadn’t found it first.

Reimers1, John W. Chapman2 1College of Earth, Ocean, and Atmospheric Sciences, Oregon State University, Corvallis, Oregon 97331, USA 2Department of Fisheries and Wildlife, Oregon State University, Hatfield Marine Science Center, 2030 SE Marine Science Dr. Newport, Oregon 97365, USA ABSTRACT: We utilized methods of sediment cultivation, catalyzed reporter deposition− fluorescence in situ hybridization, scanning electron microscopy, and 16s rRNA gene sequencing to investigate the presence of novel filamentous cable bacteria (CB) in estuarine sediments bioturbated by the mud shrimp Upogebia pugettensis Dana and also to test for trophic connections between the shrimp, its commensal bivalve (Neaeromya rugifera), and the sediment. Agglutinated sediments from the linings of shrimp burrows exhibited higher abundances of CB compared to surrounding suboxic and anoxic sediments. Furthermore, CB abundance and activity increased in these sedi- ments when they were incubated under oxygenated seawater. Through core microbiome analy- sis, we found that the microbiomes of the shrimp and bivalve shared 181 taxa with the sediment bacterial community, and that these shared taxa represented 17.9% of all reads. Therefore, bac- terial biomass in the burrow sediment lining is likely a major food source for both the shrimp and the bivalve. The biogeochemical conditions created by shrimp burrows and other irrigators may help promote the growth of CB and select for other dominant members of the bacterial commu- nity, particularly a variety of members of the Proteobacteria.

Six criteria reveal isopod, Orthione griffenis, was first discovered on the that Orthione is introduced to North America: its Pacific coast of North America in Washington in 1988 conspecificity with disjunct Asian populations, its and next in California in 1992. The range of Orthione earliest (1950s) collections in Asia, its late discovery presently extends from British Columbia to Baja among symbiotic species associated with Upogebia, California, where it infests at least two species of the its historical absence, and its appearance in North native estuary mud shrimp, Upogebia. Intense Orthi- America coincident with extensive new ballast water one infestations are associated with the apparent traffic from Asia. Orthione is the first recognized demise of many local populations of Upogebia bopyrid isopod invasion globally. Coexistence of U. pugettensis yet nonindigenous origins of Orthione in pugettensis, which are ecosystem engineers, with its North America and thus the ecological significance of newly acquired parasite cannot be assumed. Orthione threatens eastern Pacific estuary ecosystems where Upogebia were previously abundant.

This list includes all candidateswho submitted theses or dissertations as a partial fulfillment of their requirements and who received their degrees from June 1966 through June1970. Allof these studies were,prepared under the direction ofDr.Henry P.Hansen,Dean of the Graduate School. The increasing number of titles in the 1960's reflects the continuing expansion of Oregon State University as a center of research and graduate study. The pre- viously published list covered a period of six years and included 1,388 titles, an average of 231 a year. This list covers only five years but includes a totalof 1,715 titles, an average of 343 titles a year. All theses and dissertations accepted since 1932 may be consulted in the Univer- sity's William Jasper Kerr Library. Masters' theses are available for interlibrary loan. Copies of all doctoral dissertations since 1957 may be obtained either in microfilm or microfilm printout from University Microfilms, Ann Arbor, Michi- gan 48106. The first compilation was published by the Oregon State System of Higher Education and covers the years 1932-1942 for all institutions in the System. Subse- quent lists for Oregon State University have been published for 1943-1959 and for 1960-1965 and are available from the University Press.

  • Particle Removal Rates by the Mud Shrimp Upogebia Pugettensis, Its Burrow, and a Commensal Clam: Effects on Estuarine Phytoplankton Abundance

Suspension-feeding activities by the shrimp and by its commensal clam, as well as parti- cle settlement within the burrow, represent 3 different components that could remove phytoplankton from water drawn into shrimp burrows. These 3 components together comprise what we call the ‘U. pugettensis shrimp-burrow complex’. In laboratory experiments, we measured particle removal by each of these components. Our results indicated that U. pugettensis itself is responsible for filter- ing the majority of phytoplankton removed by the U. pugettensis shrimp-burrow complex at phyto- plankton concentrations of 0.12 mg C l–1, with filtration by C. californica becoming increasingly important at phytoplankton concentrations of 0.48 mg C l–1. Particle settlement in the burrow and adhesion to the burrow wall may also be responsible for removal of substantial proportions of phyto- plankton.
