Marine fauna of county Wexford, Ireland: the fauna of rocky shores and sandy beaches

Abstract

Information accumulated during 20 years of investigations on the coast of County Wexford is summarised. Topics include shore descriptions, faunal records, transectal surveys on rocky shores and sandy beaches, cryptofaunal studies on rocky shores, and ecology, reproduction and population dynamics of many of the dominant species. Studies were mainly carried out on exposed and sheltered rocky shores in the region of Camsore Point, Forlorn Point and Hook Head, and sandy beaches at Kilmore Quay, Camsore, Came, Rosslare Harbour and Rosslare Point, but some collections were made in a wide range of habitats throughout the county. A total of 484 taxa were recorded. Carnsore is the type locality for four species of oligochaete and two more are yet to be described. The fauna lacks some of the elements of west Irish coasts but is richer than on the mid-eastern coast owing to the presence of southern species. Differences in species abundance and population structure on south and east coasts are described, and possible reasons for the differences are discussed
