Energy Values of Marine Benthic Invertebrates from the Canadian Arctic
MARINE ECOLOGY - PROGRESS SERIES Published September 10 Mar. Ecol. Prog. Ser. 1 Energy values of marine benthic invertebrates from the Canadian Arctic J. W. Wacasey, E. G.Atkinson Arctic Biological Station, Department of Fisheries and Oceans, 555 St. Pierre Boulevard, Ste-Anne-de-Bellevue, Quebec H9X 3R4,Canada ABSTRACT: Calonc values were determined for 121 species of cold-water benthic invertebrates, 109 of which are representative of a soft bottom community in Frobisher Bay, Northwest Territories (Canada). The mean calonc value for the community was 5.424 kcal g-' ash-free dry weight (SD f 0.403). This is not significantly different from values from lower latitudes, as has been suggested for planktonic communities. With one exception, the Ascidiacea, there were no significant differences in mean caloric value among major taxa. The lnterspecific distnbution of AFDW caloric value is discussed; present data support the growlng evidence that the natural pattern is symmetrical with values concentrated about a mean of 5.4 to 5.7 kcal g-' AFDW for benthic invertebrates. Caloric equivalents for biomass estimates and large-scale community comparisons may be derived from the regression of dry weight caloric value on percent organic content (dry weight): Y (kcal g-' AFDW) = -0.3897 + 0.0605 X (% organic content). when the organic fraction is determined directly. Two problematical taxa, Porifera and Echinodermata, are discussed and separate regressions are presented. INTRODUCTION community mean value, taxonomic variations, and interspecific distribution pattern of caloric values is Although energy values of many cold-water marine discussed. The relationships between caloric value and zoobenthic invertebrates are available (Ellis 1960, organic content gives equations from which fast, reli- Brawn et al. -
Spermatogenesis of the Gastropod, Pila Globosa, with S Pecial
1959 423 Spermatogenesis of the Gastropod , Pila globosa, with S pecial Reference to the Cytoplasmic Organelles G. P. Sharma, Brij L. Gupta , and O. P. Mittal Department of Zoology, Panjab University , Hoshiarpur, Punjab, India Received December 22, 1958 Introduction The gastropods constitute the classical material for the study of sperma togenesis. The two most important aspects which have been the subject of controversy for the cytologists are the acrosome formation and the dimorphic sperms. Whereas the disagreement regarding the acrosome formation has been in the pulmonates, the problem of dimorphic sperms is restricted to the order prosobranchia of the class Gastropoda. According to Wilson (1925), von Siebold (1837) was the first worker to report dispermy in the prosobranch, Paludina (now called Viviparus). He described two types of sperms, viz., worm-shaped or oligopyrene, and the hair-shaped or eupyrene. This preliminary report of von Siebold was later on confirmed and ex tended by a number of subsequent workers like Meves (1902), Gatenby (1919), Ankel (1924), Alexenko (1926), Tuzet (1930), Woodard (1940), Pol lister and Pollister (1943) etc., in Viviparus (Paludina) vivipara, and a number of other prosobranchs. All of these workers have based their obser vations on the fixed and sectioned material. Pollister and Pollister (1943) have, however, studied only the chromosomes and centrosomes in both the eupyrene and the oligopyrene sperms of Viviparus vivipara. Recently Hanson et al. (1952) have worked out the detailed structure of the eupyrene and the oligopyrene sperms in the prosobranch, Viviparus. These authors examined the living cells under the phase-contrast microscope and the fixed material with the electron microscope and the various cyto chemical techniques. -
The Influence of Ocean Warming on the Provision of Biogenic Habitat by Kelp Species
University of Southampton Faculty of Natural and Environmental Sciences School of Ocean and Earth Sciences The influence of ocean warming on the provision of biogenic habitat by kelp species by Harry Andrew Teagle (BSc Hons, MRes) A thesis submitted in accordance with the requirements of the University of Southampton for the degree of Doctor of Philosophy April 2018 Primary Supervisor: Dr Dan A. Smale (Marine Biological Association of the UK) Secondary Supervisors: Professor Stephen J. Hawkins (Marine Biological Association of the UK, University of Southampton), Dr Pippa Moore (Aberystwyth University) i UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences Doctor of Philosophy THE INFLUENCE OF OCEAN WARMING ON THE PROVISION OF BIOGENIC HABITAT BY KELP SPECIES by Harry Andrew Teagle Kelp forests represent some of the most productive and diverse habitats on Earth, and play a critical role in structuring nearshore temperate and subpolar environments. They have an important role in nutrient cycling, energy capture and transfer, and offer biogenic coastal defence. Kelps also provide extensive substrata for colonising organisms, ameliorate conditions for understorey assemblages, and generate three-dimensional habitat structure for a vast array of marine plants and animals, including a number of ecologically and commercially important species. This thesis aimed to describe the role of temperature on the functioning of kelp forests as biogenic habitat formers, predominantly via the substitution of cold water kelp species by warm water kelp species, or through the reduction in density of dominant habitat forming kelp due to predicted increases in seawater temperature. The work comprised three main components; (1) a broad scale study into the environmental drivers (including sea water temperature) of variability in holdfast assemblages of the dominant habitat forming kelp in the UK, Laminaria hyperborea, (2) a comparison of the warm water kelp Laminaria ochroleuca and the cold water kelp L. -

V- > • Fairbanks, Alaska December, 197 9 Abstract This studv presents information on the tnxonomv and distribution of the marine prosobranch gastropod and bivalve mollusks from the waters surrounding Alaska. Three hundred fifty-two species of prosobranch gastropods and 202 species of bivalves are reported from these waters. Over 3,000 lots of specimens, representing 330 species and literature sources form the basis of this study. References, synonymy, geographic and bathymetric ranges are provided for each species. Characteristics used to identify the species of 66 genera are presented in tabular form. The greatest number of species is reported from the southern Bering Sea, <-ite fewest from the Beaufort Sea. Most of the species have wide ranges in the eastern or western Pacific. New collecting records reported here extend the known ranges of 27 species. Eight species were previously unknown from Alaskan waters. -
Velutina Velutina ((OF Müller, 1776), )
Arctic Megabenthos Velutina velutina ((O. F. Müller, 1776), ) Phylum: Mollusca Class: Gastropoda Order: Littorinimorpha Family: Velutinidae Genus: Velutina Synonyms: Velutina laevigata (O. F. Müller, 1777), Velutina laevigata (Linnaeus, 1758) Description. - Shell with 3 convex rounded whorls, deeply impressed suture and well developed calcareous layer and periostracum. Upper part of spire projects slightly above inflated last whorl which occupies almost entire shell. Protoconch small, white, uncovered by periostracum. Periostracum fibrous, yellowish or brown, tightly adherent to shell forming closely spaced discontinuous spiral crests. Intervals between crests are equal to or 2 times the crest thickness. Adult individuals with 22-30 crests on last whorl. Sculpture on calcareous layer of ir¬regular growth lines crossing spiral riblets. The ribs correspond to crests on per¬iostracum. Aperture broad, almost rounded, opaque-white on inside. Inner lip slightly turned back on outside. Measurements. - Largest seen specimen: height 15 mm, length 26 mm, width 20 mm. Remarks. - The species is separated from the closely related V. (V.) schneideri by a more strongly developed periostracum structure with 22-30 spiral crests on last whorl. Distribution. - In the Arctic Region the species is circumpolar. In the Pacific it occurs in the Bering and northern parts of Okhotsk and Japan Seas as well as Gulf of Alaska. In accordance with MacGinitie (1959), the species is found in Monterey Bay (California) and in the Atlantic Ocean it is distributed to Cape Hatteras and Portugal. Ecology. - The species occurs at depths from 0.5 to 408 m, most common at 20 to 150 m on mud, gravel and pebble mixture and muddy sand substrata, often in Laminaria and other algae as well as on ascidians.
