Cold seeps fluids provide an additional source of energy for various sulfide- and 27 hydrocarbon-harvesting bacteria, often in symbiosis with invertebrates, attracting a variety of other 28 organisms including crustaceans (e.g., Levin 2005; Vanreusel et al. 2009; Vrijenhoek 2013). The 29 percentage of crustaceans of all macrofaunal specimens is highly variable locally in modern seeps, from 30 0–>50% (Dando et al. 1991; Levin et al. -

Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans
Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans by Robert George Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Robert George Young, March, 2016 ABSTRACT MOLECULAR SPECIES DELIMITATION AND BIOGEOGRAPHY OF CANADIAN MARINE PLANKTONIC CRUSTACEANS Robert George Young Advisors: University of Guelph, 2016 Dr. Sarah Adamowicz Dr. Cathryn Abbott Zooplankton are a major component of the marine environment in both diversity and biomass and are a crucial source of nutrients for organisms at higher trophic levels. Unfortunately, marine zooplankton biodiversity is not well known because of difficult morphological identifications and lack of taxonomic experts for many groups. In addition, the large taxonomic diversity present in plankton and low sampling coverage pose challenges in obtaining a better understanding of true zooplankton diversity. Molecular identification tools, like DNA barcoding, have been successfully used to identify marine planktonic specimens to a species. However, the behaviour of methods for specimen identification and species delimitation remain untested for taxonomically diverse and widely-distributed marine zooplanktonic groups. Using Canadian marine planktonic crustacean collections, I generated a multi-gene data set including COI-5P and 18S-V4 molecular markers of morphologically-identified Copepoda and Thecostraca (Multicrustacea: Hexanauplia) species. I used this data set to assess generalities in the genetic divergence patterns and to determine if a barcode gap exists separating interspecific and intraspecific molecular divergences, which can reliably delimit specimens into species. I then used this information to evaluate the North Pacific, Arctic, and North Atlantic biogeography of marine Calanoida (Hexanauplia: Copepoda) plankton. -
(Southern Ocean) Hydrothermal Vents: What More Can We Learn from an Ellipse?

In many cases isotopic variability can be influenced by the scale of sampling and biological characteristics including body size or sex. Sample size-corrected (SEAc) and Bayesian (SEAb) standard ellipse areas and generalised least squares (GLS) models were used to explore the spatial variability of δ13C and δ15N in Kiwa tyleri (decapod), Gigantopelta chessoia (peltospirid gastropod) and Vulcanolepas scotiaensis (stalked barnacle) collected from 3 hydrothermal vent field sites (E2, E9N and E9S) on the East Scotia Ridge (ESR), Southern Ocean. SEAb only revealed spatial differences in isotopic niche area in male K. tyleri. However, the parameters used to draw the SEAc, eccentricity (E) and angle of the major SEAc axis to the x-axis (θ), indicated spatial differences in the relationships between δ13C and δ15N in all 3 species. -

Benvenuto, C and SC Weeks. 2020
--- Not for reuse or distribution --- 8 HERMAPHRODITISM AND GONOCHORISM Chiara Benvenuto and Stephen C. Weeks Abstract This chapter compares two sexual systems: hermaphroditism (each individual can produce gametes of either sex) and gonochorism (each individual produces gametes of only one of the two distinct sexes) in crustaceans. These two main sexual systems contain a variety of alternative modes of reproduction, which are of great interest from applied and theoretical perspectives. The chapter focuses on the description, prevalence, analysis, and interpretation of these sexual systems, centering on their evolutionary transitions. The ecological correlates of each reproduc- tive system are also explored. In particular, the prevalence of “unusual” (non- gonochoristic) re- productive strategies has been identified under low population densities and in unpredictable/ unstable environments, often linked to specific habitats or lifestyles (such as parasitism) and in colonizing species. Finally, population- level consequences of some sexual systems are consid- ered, especially in terms of sex ratios. The chapter aims to provide a broad and extensive overview of the evolution, adaptation, ecological constraints, and implications of the various reproductive modes in this extraordinarily successful group of organisms. INTRODUCTION 1 Historical Overview of the Study of Crustacean Reproduction Crustaceans are a very large and extraordinarily diverse group of mainly aquatic organisms, which play important roles in many ecosystems and are economically important. Thus, it is not surprising that numerous studies focus on their reproductive biology. However, these reviews mainly target specific groups such as decapods (Sagi et al. 1997, Chiba 2007, Mente 2008, Asakura 2009), caridean Reproductive Biology. Edited by Rickey D.

Stalked Barnacles
*Manuscript Click here to view linked References Stalked barnacles (Cirripedia, Thoracica) from the Upper Jurassic (Tithonian) Kimmeridge Clay of Dorset, UK; palaeoecology and bearing on the evolution of living forms Andy Gale School of Earth and Environmental Sciences, University of Portsmouth, Burnaby Building, Burnaby Road, Portsmouth PO1 3QL; E-mail address: [email protected] A B S T R A C T New thoracican cirripede material from the Kimmeridge Clay (Upper Jurassic, Tithonian) is described. This includes a log, encrusted on the lower surface with hundreds of perfectly preserved, articulated specimens of Etcheslepas durotrigensis Gale, 2014, and fewer specimens of Concinnalepas costata (Withers, 1928). Some individuals are preserved in life position, hanging from the underside of the wood, and the material provides new morphological information on both species. It appears that Martillepas ovalis (Withers, 1928), which occurs at the same level (Freshwater Steps Stone Band, pectinatus Zone) attached preferentially to ammonites, whereas E. durotrigensis and C. costata used wood as a substrate for their epiplanktonic lifestyle. Two regurgitates containing abundant barnacle valves, mostly broken, and some bivalve fragments, have been found in the Kimmeridge Clay. These were produced by a fish grazing on epiplanktonic species, and are only the second example of regurgitates containing barnacle valves known from the fossil record. The evolution of modern barnacle groups is discussed in the light of the new Jurassic material as well as recently published molecular phylogenies. New clades defined herein are called the Phosphatothoracica, the Calamida and the Unilatera. Keywords Epiplanktonic barnacles Kimmeridge Clay predation 1. INTRODUCTION Amongst the most remarkable fossils collected by Steve Etches from the Kimmeridge Clay of Dorset are articulated stalked barnacles. -

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. -
The Cirripedia of New Caledonia
The Cirripedia of New Caledonia Diana S. lONES Western Australian MlISeum [email protected] The Indo-Pacific deep-sea benthos was investigated by major expeditions such as those of «Challenger» (1873-1876), «Investigator» (1884-] 887), «Valdiva» (1898-] 899), «Siboga» (1899 1900), «Albatross» (1907-1910) and «Galathea» (1950-52). However, none of these expeditions col lected in the waters of New Caledonia and its surrounding areas. The cirripede fauna of the region was first documented through the brief report of Fischer (1884), who described the shallow water bar nacles of New Caledonia. Fischer briefly listed 15 species from specimens deposited in the Musee de Bordeaux by the missionaries Montrouzier and Lambert. From that time, there was no documenta tion of the fauna until the latter half of the 20th century, when a rigorous collection and taxonomic program was conducted in the region supported through IRD (ORSTOM) and the Museum national d'Histoire naturelle, Paris. Since 1978, numerous barnacle specimens have been collected in the deep waters off Vanuatu (MUSORSTOM 8 1994), New Caledonia, the Chesterfield and Loyalty Islands (BIOCAL 1985, MUSORSTOM 41985, LAGON 1985, MUSORSTOM 5 1986.CHALCAL2 1986, SMIB21986.SMIB31987.CORAIL2 1988,MUSORSTOM61989.VAUBAN 1989,ALIS 1989, SMIB61990,BERYX21992,BATHUS21993,SMIB81993,HALIPR0219(6),the Wall ace and Futuna Islands, Combe.

Examination of these collections has yielded an exceptional diversity of thoracican cirripedes. Buckeridge (1994, 1997) provided a comprehensive account of the deep-sea Verrucomorpha (Cirripedia) from collections made by several French cruises in the New Caledonian area and the Wallis and Futuna Islands.
