Electron microscopy at the Marine Biological Association: 1961-2006. Occasional Publication of the Marine Biological Association 23

This memoir recalls the instruments in the Electron Microscope Unit and the staff, students and visitors who used them. Accessory equipment is also described because much of it was innovative and built in the laboratory, also, much of the science would not have been possible without it. This publication includes 33 figures, 4 plates and 7 appendices. The appendices record that 54 MBA staff and 196 students and visitors have used the microscopes and that 413 titles have been published (to the end of 2006).

The Russell Cycle. An update and review of trends in zooplankton and fish larvae off Plymouth 1924-2009. Occasional Publication of the Marine Biological Association 24

Regular plankton sampling off Plymouth by the Marine Biological Association (MBA) has been carried out from the early 1900s. Much of the sample analysis and description of the results was carried out by Sir Frederick Russell and Professor Alan Southward (AJS), the latter having completed the organisation and transfer of the paper records to digital files. The current authors have transferred the main data files of AJS on zooplankton and fish larvae to the MBA long-term database (including various editing and checking against original analysis records and published data) together with adding the data for 2002-2009. In this report the updated time-series are reviewed in the context of earlier work, particularly with respect to the Russell Cycle. It is not intended as an exhaustive analysis. Brief details of the sampling and comments on data processing are given in an appendix.

Marine Zooplankton of Southern Britain - Part 1: Radiolaria, Heliozoa, Foraminifera, Ciliophora, Cnidaria, Ctenophora, Platyhelminthes, Nemertea, Rotifera and Mollusca. Occasional Publication of the Marine Biological Association 25

This series of three guides (of which this is Part 1) collates taxonomic identification information for the zooplankton groups recorded off south-west Britain , primarily for local identification and training purposes. However, because prevailing currents also bring oceanic zooplankton into the English Channel , the range of species sampled off Plymouth covers the majority found over the shallower parts of northern European continental shelf (excluding the Mediterranean Sea ), so the guides should be more widely useful and hopefully make tackling zooplankton identification easier for a wider audience. The commonest truly planktonic species and the most widely studied groups are covered in most detail, but some information is also included on benthic, epibenthic and parasitic species that are sampled occasionally. For all groups there is at least information on their morphology, guidance on their identification and bibliographies giving identification resources.

Identification of the copepodite developmental stages of twenty-six North Atlantic copepods. Occasional Publication of the Marine Biological Association No. 21 (revised edition)

This identification guide to the copepodite developmental stages of twenty-six North Atlantic copepods has been revised and extended, to include new information, to update the taxonomy and to give additional details on how to determine sex in the later copepodite stages of gymnoplean copepods.
