Zootaxa: Systematics of the Genus Scleroplax Rathbun, 1893
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).

Abstract Ghost shrimps of Callianassidae and Ctenochelidae are soft-bodied, usually heterochelous decapods representing major bioturbators of muddy and sandy (sub)marine substrates. Ghost shrimps have a robust fossil record spanning from the Early Cretaceous (~ 133 Ma) to the Holocene and their remains are present in most assemblages of Cenozoic decapod crustaceans. Their taxonomic interpretation is in flux, mainly because the generic assignment is hindered by their insufficient preservation and disagreement in the biological classification. Fur- thermore, numerous taxa are incorrectly classified within the catch-all taxonCallianassa . To show the historical patterns in describing fos- sil ghost shrimps and to evaluate taphonomic aspects influencing the attribution of ghost shrimp remains to higher level taxa, a database of all fossil species treated at some time as belonging to the group has been compiled: 250 / 274 species are considered valid ghost shrimp taxa herein. -

Shrimp Neotrypaea Californiensis to Intertidal Shell and Mud Habitats
MARINE ECOLOGY PROGRESS SERIES Published April 30 Mar Ecol Prog Ser l Effects of substrate selection and post-settlement survival on recruitment success of the thalassinidean shrimp Neotrypaea californiensis to intertidal shell and mud habitats Kristine L. Feldmanlr*,David A. ~rmstrongl,David B. ~ggleston'~",Brett R. ~umbauld~ 'School of Fisheries, Box 357980, University of Washington, Seattle, Washington 98195, USA 'Washington State Department of Fish and Wildlife, Willapa Bay Field Station, PO Box 190, Ocean Park, Washington 98640, USA ABSTRACT: We quantified recruitment of young-of-the-year (YOY)burrowing thalassinidean shrimp Neotrypaea californiensis to 2 habitats of differing structural complexity-epibenthic bivalve shell and bare mudflat-and examined how differential settlement and post-settlement predation influence patterns of YOY abundance. Local densities of shrimp were quantified prlor to construction of shell habitat in Grays Harbor estuary, Washington (USA). Subsequent recruitment of YOY shrimp to epiben- thic shell and bare mudflat was measured during a peak settlement pulse and 10 mo post-settlement. In addition, patches of sediment overlying shell within the shell plot ('subsurface shell') were sampled 10 mo post-settlement. Differential settlement in shell and mud habitats was quantified in field and laboratory experiments. We also examined predator-prey interactions between YOY Dungeness crabs Cancer magister and newly settled shrimp in shell habitat in a laboratory experiment in which prey consumption crab-' was quantified as a function of shrimp density. Results of our studies indicate that dense coverage of epibenthic shell applied to the intertidal site reduced recruitment of ghost shrimp. Epibenthic shell habitat had significantly fewer YOY shrimp than bare mudflat at peak settlement and 10 mo post-settlement, and significantly fewer shrimp than 'subsurface shell' at 10 mo post-settlement. -

A New Genus for the Central American Crab Pinnixa Costaricana Wicksten, 1982 (Crustacea: Brachyura: Pinnotheridae)
15 April 1997 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON 110(1 ):69-73. 1997. A new genus for the Central American crab Pinnixa costaricana Wicksten, 1982 (Crustacea: Brachyura: Pinnotheridae) Ernesto Campos and Mary K.

This genus shares with Alarconia Glassell, 1938, Indopinnixa Manning & Morton, 1987, Scler- oplax Rathbun, 1893 and Pinnixa White, 1846, a carapace wider than long, and third pair of walking legs the longest. Glassella is distinguished from other genera by: MXP3 with ischium-merus pyriform, carpus larger than the conical propodus, and small digitiform dactylus inserted sub-distally on the inner face of propodus. The type species is redescribed and illustrated. Pinnixa costaricana was originally de tonoma de Baja California. The information scribed by Wicksten (1982) and placed in used on the type species of Indopinnixa, I. the genus Pinnixa White, 1846, because of sipunculana, was obtained from published its carapace shape and relative length and description and figures, although critical shape of the walking legs.

Disturbance Facilitates the Coexistence of Antagonistic Ecosystem Engineers in California Estuaries
Ecology, 95(8), 2014, pp. 2277–2288 Ó 2014 by the Ecological Society of America Disturbance facilitates the coexistence of antagonistic ecosystem engineers in California estuaries 1,2,4 1 3 2 MAX C. N. CASTORANI, KEVIN A. HOVEL, SUSAN L. WILLIAMS, AND MARISSA L. BASKETT 1Coastal and Marine Institute Laboratory and Department of Biology, San Diego State University, San Diego, California 92182 USA 2Department of Environmental Science and Policy, University of California, Davis, California 95616 USA 3Bodega Marine Laboratory and Department of Evolution and Ecology, University of California–Davis, Bodega Bay, California 94923 USA Abstract. Ecological theory predicts that interactions between antagonistic ecosystem engineers can lead to local competitive exclusion, but disturbance can facilitate broader coexistence. However, few empirical studies have tested the potential for disturbance to mediate competition between engineers. We examined the capacity for disturbance and habitat modification to explain the disjunct distributions of two benthic ecosystem engineers, eelgrass Zostera marina and the burrowing ghost shrimp Neotrypaea californiensis, in two California estuaries. Sediment sampling in eelgrass and ghost shrimp patches revealed that ghost shrimp change benthic biogeochemistry over small scales (centimeters) but not patch scales (meters to tens of meters), suggesting a limited capacity for sediment modification to explain species distributions. To determine the relative competitive abilities of engineers, we conducted reciprocal transplantations of ghost shrimp and eelgrass. Local ghost shrimp densities declined rapidly following the addition of eelgrass, and transplanted eelgrass expanded laterally into the surrounding ghost shrimp-dominated areas. When transplanted into eelgrass patches, ghost shrimp failed to persist. Ghost shrimp were also displaced from plots with structural mimics of eelgrass rhizomes and roots, suggesting that autogenic habitat modification by eelgrass is an important mechanism determining ghost shrimp distributions.
