  • Stimulation of Filter Feeding by Amino Acids in Three Porcelain Crab Species: Petrolisthes Cinctipes, Petrolisthes Eriomerus, and Pachycheles Rudis
    Stimulation of filter feeding by amino acids in three porcelain crab species: Petrolisthes cinctipes, Petrolisthes eriomerus, and Pachycheles rudis Sarah Green Exploratory 2, Adaptations ofMarine Mammals, Prof. Charlie Hunter Oregon Institute ofMarine Biology, University of Oregon, Charleston, Oregon 97420 Introduction Petrolisthes cinctipes, a species ofporcelain crab, is commonly found in the higher to mid-intertidal zones ofthe rocky shores ofOregon (Wicksten, 1973). Petrolisthes eriomerus and Pachycheles rudis, the other two species ofporcelain crab found on the Oregon coast can be found in the low intertidal zone. All three species can be found under rocks and among mussels in mussel beds (Sept, 1999). The three species ofporcelain crab filter feed, fanning plankton and detritus (Petrolisthes cinctipes and Pachycheles rudis) from the water, or pelagic diatoms, benthic diatoms, and green algal filaments from the water (Petrolisthes eriomerus) (MagGinite, 1937; Wicksten, 1973). The mechanics offilter feeding in porcelain crabs has been thoroughly documented by Wicksten (1973). Food particles can be trapped by alternately flexing the endopodites ofthe third maxillapeds. The food particles are then removed from the setae on the third maxillapeds by the setose ends ofthe second maxillapeds. Food particles are then selected and sorted by the inner mouth parts. Little research has been reported on compounds promoting feeding behavior in porcelain crabs. L-tyrosine has been shown to elicit a feeding response in Petrolisthes cinctipes, as have other amino acids. As there are no particles in the water when testing an amino acid, chemoreception ofsmall compounds must stimulate the feeding response (Hartman et aI., 1977). I hypothesize that the stimulation ofthe feeding response in Petrolisthes cinctipes, Petrolisthes eriomerus, and Pachycheles rudis will differ in response to various amino acids because ofthe their location in the intertidal.

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form.

  • A Comparative Analysis of Morphological, Physiological, And
    AN ABSTRACT OF THE THESIS OF Jonathon Harris Stillman for the degree of Doctor of Philosophy in Zoology presented on December 4, 1998. Title: A Comparative Analysis of Morphological, Physiological, and Biochemical Adaptation to Abiotic Stress in Intertidal Porcelain Crabs, Genus Petrolisthes. Redacted for Privacy Abstract approved: George N. Somero Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined using porcelain crabs, genus Petrolisthes. Species of Petrolisthes from intertidal and subtidal microhabitats of four biogeographic regions of the Eastern Pacific were used in phylogenetically-based comparative analyses of morphological, physiological, and biochemical adaptation to environmental stress. A phylogenetic tree based on the sequence of the 16sRNA gene was developed to facilitate these analyses. Organismal thermal tolerance limits are adapted to match maximal microhabitat temperatures. Acclimation of thermal tolerance limits suggests that temperate intertidal zone species are living close to their thermal maximum in nature. Respiratory responses to emersion vary among species from different vertical zones. Experimental examination of oxygen consumption rates and lactate accumulation during emersion suggests that intertidal species are able to respire in air using thin membranous regions on the ventral meral segments of their legs (leg membranes). Leg membrane size is positively correlated with body size across species, but not within a single species. Evolutionary analyses indicate that leg membranes may not have evolved for purposes of aerial respiration, but their presence may have allowed intertidal and subtidal species to achieve larger body sizes and higher metabolic rates.

Porcelain crabs, genus Petrolisthes, have been powerful crustacean models for environmental and evolutionary physiology with respect to thermal adaptation and understanding responses of marine organisms to climate change. Here, we present a large-scale EST sequencing and cDNA microarray database project for the porcelain crab Petrolisthes cinctipes. Methodology/Principal Findings: A set of ,30K unique sequences (UniSeqs) representing ,19K clusters were generated from ,98K high quality ESTs from a set of tissue specific non-normalized and mixed-tissue normalized cDNA libraries from the porcelain crab Petrolisthes cinctipes. Homology for each UniSeq was assessed using BLAST, InterProScan, GO and KEGG database searches. Approximately 66% of the UniSeqs had homology in at least one of the databases.

In total, 105 species of these parasites (~18% of all bopyrids) are documented from Recent squat lobsters and porcelain crabs in the superfamilies Chirostyloidea and Galatheoidea. Aside from one endoparasite, all the bopyrids reported herein belong to the branchially infesting subfamily Pseudioninae. Approximately 29% (67 of 233 species) of pseudionine species parasitize squat lobsters and 16% (38 of 233 species) parasitize porcelain crabs.

The taxonomic history of P. africana is summarized, and the taxonomic implications of the DNA analysis are discussed. The observations that the South African population appeared suddenly and that it is located in and around a major international harbour, strongly suggest that it represents a recent shipping introduction. Porcellana africana was first detected at a single site within Saldanha Bay in 2012, but by 2016 was abundant under intertidal boulders and within beds of the invasive mussel Mytilus galloprovincialis across most of the Bay.

By no means is it a complete list of all possible prey types. It is simply what has been found in past ChesMMAP and NEAMAP diet studies. A copy of this document is stored in both the ChesMMAP and NEAMAP lab network drives in a folder called ID Guides, along with other useful identification keys, articles, documents, and photos. If you want to see a larger version of any of the images in this document you can simply open the file and zoom in on the picture, or you can open the original file for the photo by navigating to the appropriate subfolder within the Fisheries Gut Lab folder.
