“…This is more clearly evident in the meiofauna than in the macrofauna. Hence, the distribution pattern of the meiofauna provides a better reflection of recent dynamic sedimentary processes (Newell et al 1990), while the distribution of the macrofauna appears to be related to their preference for more stable habitats.…”

Features of spatial distribution of benthic infauna in a Mediterranean shallow-water bay

Abstract. The unique hydrography of the Western Mediterranean Sea does not favour the formation of typical estuaries, although it does favour that of other land-sea systems. However, in Els Alfacs, a shallow-water bay situated in the Ebre Delta (northeast Spain), where there are considerable continental inputs, the distribution patterns of the macrofauna and the meiofauna reflect a hydrographical regime very similar to that of an estuary. During July 1987, 23 stations were sampled in the Alfacs Bay using plastic cores. The distribution pattern of the meiofauna follows a gradient and presents a less marked zonation than the macrofauna. Nevertheless, in both cases the peak densities of both faunal components are spatially separated from the principal site of freshwater inflow. The average density of the macrofauna (10 430 individuals/m 2) and the meiofauna (704 100 individuals/ m 2) occurs in the bay during the period of maximum flow (spring-summer), and as such this bay is one of the most productive areas of the Western Mediterranean.

“…The need for further studies enabling long-term impacts of sewage effluents on marine benthic ecosystems cannot be over-emphasized. Recent studies have indicated the value of meiofauna as sensitive indicators of the impacts of pipe-borne effluents (14). Such studies should also provide important verification data for dispersion models.…”

The environmental implications of implementing the requirement for treatment of coastal sewage prior to discharge, which were put forward in an EC draft Directive on municipal waste‐water treatment, are examined. In order to establish the current situation, the results of a national survey of coastal and estuarine sewage discharges are presented. A review of the impact of sewage discharges on the marine environment is presented in conjunction with an assessment of the impact of sewage‐treatment processes on the land and in the air. These aspects are integrated into overall conclusions about net environmental impact. Finally, a decision‐tree approach to the assignment of priority to additional action required at individual locations is developed.

“…Later in the mid 80s, Tioxide planned a new plant in Malaysia and during this time Richard mentored both Tioxide staff and the regulator's own environmental scientists in theory and practice of Environmental Impact Assessment (EIA) and environmental monitoring, whilst Barbara Brown and QMC colleagues contributed tropical reef and wetland ecological expertise. The relationship with Tioxide yielded >75 confidential consultancy reports, made possible by collaboration with Richard's twin brother Peter and Physalia Ltd (Marcus Trett and colleagues) who provided essential macrobenthic and meiofaunal analytical expertise (Newell et al, 1990). During this time Richard maintained his links with academia via his PhD student John Bythell based in the Caribbean (1984)(1985)(1986)(1987)(1988)) (now a Professor at Newcastle upon Tyne) and continued to publish with Professor Sandy Shumway and colleagues at University of Connecticut (e.g.…”

and grew up in Whitstable, Kent, the eldest son of six, and from the age of eight he was enlisted together with twin brother Peter by their father Gordon, to help with fieldwork on mud flats at Whitstable, where Gordon was working on the life cycle of Arenicola marina. This laid the foundation for a career in marine science, with Richard achieving a 1st in Zoology at Queen Mary College (QMC). He then took up a lectureship at Westfield College whilst doing his PhD on the biology of Hydrobia ulvae. Subsequently research with a series of talented PhD studentsall investigating aspects of the physiology of intertidal animals (e.g. Newell & Pye, 1971)enabled him to build towards writing The Biology of Intertidal Animals (1970) which became an essential companion for students of marine biology. Most of Richard's PhD students from QMC days have now retired; however, Professor Islay Marsden and Professor Barbara Brown have continued to publish and build on his influence and interest in adaptive physiology. Richard and his father revised Marine Plankton -A Practical Guide (1977), another marine biology student essential and generally regarded as a first-class reference work for identification of plankton.
