They cover a review of marine megafauna with tidal-stream environments; climate-driven trophic cascades affecting seabirds around the British Isles; circum-global invasion by the brown seaweed Sargassum muticum; simple, scale-dependent patterns emerge from very complex effects: an example from the inter-tidal mussels Mytilus galloprovincialis and Perna perna; the contributions of the genus Littorina to the field of evolutionary ecology; and spatial, temporal, and taxonomic variation in coral growth and implications for the structure and function of coral reef ecosystems.
Larval feeding has been lost at least once in the genus Littorina, but nonfeeding larvae of some species in the genus retain the velum, using its marginal cells for endocytotic uptake of capsular albumen (3).
A cladistic phylogeny of the genus Littorina (Gastropoda): Implications for evolution of reproductive strategies and for classification.
Fossil records together with a recent phylogenetic analysis based on morphological variation of the approximately 20 existing species of the genus Littorina (Reid 1990a) suggest that in the Upper Pliocene at least two independent lineages immigrated from the Pacific Ocean to the northern Atlantic, and led to the six recent species of Littorina in this area (Reid 1990b).
