Reproduction and fecundity of the musselmytilus edulis at helgoland (North sea)
Springer Science and Business Media LLC - Tập 36 - Trang 243-255 - 1983
M. Sprung
The reproductive cycle of aMytilus edulis population in the lower tidal zone at the island of Helgoland from Spring 1980 to Summer 1981 is described. In both years the spawning period extended from the end of April until the end of June at water temperatures between 6° and 14°C. The gametes were built up again in autumn and most individuals were mature in February. Sex ratio did not differ signifi...... hiện toàn bộ
Age and growth of Glycymeris longior (Sowerby, 1832) clam at the southern edge of its distribution (Argentine Sea)
Springer Science and Business Media LLC - - 2020
Lucas H. Gimenez, María del Socorro Doldan, Paula C. Zaidman, Enrique M. Morsan
Even though Glycymeris longior is a clam widely distributed in the SW Atlantic Ocean, little is known about its biology and life history. The present study assessed the periodicity of the internal growth increments of G. longior using thin shell sections. Each internal growth increment was composed of two alternating bands: a translucent band (light-coloured when viewed with transmitted light) and...... hiện toàn bộ
Investigation of the effects of current velocity on mussel feeding and mussel bed stability using an annular flume
Springer Science and Business Media LLC - Tập 56 - Trang 3-12 - 2002
John Widdows, John S. Lucas, Mary D. Brinsley, Peter N. Salkeld, Fred J. Staff
An annular flume was used to measure the effect of increasing current velocity on mussel (Mytilus edulis) feeding rate and the stability of mussel beds sampled from the mouth of the Exe estuary (SW England). It was found that, in contrast to earlier flume studies, the feeding rates of mussels from open coast sites were unaffected by current velocities up to 0.8 m s–1. Algal cell depletion in the ...... hiện toàn bộ

Interrelationships of bacteria, meiofauna and macrofauna in a Mediterranean sedimentary beach (Maremma Park, NW Italy)
Springer Science and Business Media LLC - Tập 61 - Trang 31-42 - 2006
Nafsika Papageorgiou, Mariapaola Moreno, Valentina Marin, Susanna Baiardo, Christos Arvanitidis, Mauro Fabiano, Anastasios Eleftheriou
Collelungo beach (Maremma Park, NW Italy), was sampled quantitatively for macrofauna, meiofauna and bacteria in May 2003; several physicochemical variables and variables associated with food availability and sediment structure were also measured. Replicated samples were collected from three sites representing natural conditions, an erosion regime, and the influence of the Ombrone River, respective...... hiện toàn bộ
Zur Morphologie und Ökologie vonPolydora ciliata undP. ligni (Polychaeta, Spionidae)
Springer Science and Business Media LLC - Tập 31 - Trang 102-116 - 1978
H. Michaelis
The polychaete wormsPolydora ciliata andP. ligni were investigated with regard to the morphology of their fifth chaetigerous segment, bearing bundles of modified bristles in a special arrangement. The development of these chaetae from late larval to adult stages is described, considering the loss of provisional bristles, the variation of shape caused by the wear and the shedding of old chaetae aft...... hiện toàn bộ
Using HPLC pigment analysis to investigate phytoplankton taxonomy: the importance of knowing your species
Springer Science and Business Media LLC - Tập 58 - Trang 77-82 - 2004
Xabier Irigoien, Bettina Meyer, Roger Harris, Derek Harbour
Phytoplankton microscopic enumerations and HPLC analyses of their pigments were performed weekly for a complete year at a coastal station in the English Channel. The taxonomic composition of the phytoplankton community was assessed using the HPLC results combined with the mathematical tool CHEMTAX in two different ways. Firstly, without using the species level taxonomic information obtained at the...... hiện toàn bộ
Bay-scale assessment of eelgrass beds using sidescan and video
Springer Science and Business Media LLC - Tập 68 - Trang 559-569 - 2014
Herb Vandermeulen
The assessment of the status of eelgrass (Zostera marina) beds at the bay-scale in turbid, shallow estuaries is problematic. The bay-scale assessment (i.e., tens of km) of eelgrass beds usually involves remote sensing methods such as aerial photography or satellite imagery. These methods can fail if the water column is turbid, as is the case for many shallow estuaries on Canada’s e...... hiện toàn bộ
Habitat-specific size structure variations in periwinkle populations (Littorina littorea) caused by biotic factors
Springer Science and Business Media LLC - Tập 63 - Trang 119-127 - 2008
Nina Eschweiler, Markus Molis, Christian Buschbaum
Shell size distribution patterns of marine gastropod populations may vary considerably across different environments. We investigated the size and density structure of genetically continuous periwinkle populations (Littorina littorea) on an exposed rocky and a sheltered sedimentary environment on two nearby islands in the south-eastern North Sea (German Bight). On the sedimentary shore, periwinkle...... hiện toàn bộ
Die Entwicklung vonMonostroma grevillei
Springer Science and Business Media LLC - Tập 8 - Trang 195-202 - 1962
Peter Kornmann
Die Entwicklung vonMonostroma grevillei zeichnet sich durch eine ungewöhnliche Variabilität aus (Schema Abb. 5). Der Lebenszyklus ist heteromorph mit einem einzelligen, kalkbohrenden Sporophyten (a). Parthenogenetische Gameten entwickeln sich zur Gestalt von Sporophyten; ihre Nachkommenschaft behält das Geschlecht der Ursprungspflanze bei (b). Ein kleiner Teil der zweigeißeligen Schwärmer kann unm...... hiện toàn bộ
