Aspects of the ecology of Patella spp. on the Portuguese coast
- 205 Downloads
Three species of the genus Patella were studied on the Portuguese coast as a specific contribution to the COST 647 programme. With little prior information existing, this paper presents new basic data on the geographical distribution, relative abundance, habitats, size-structure of populations, and reproductive cycles of P. depressa Pennant, 1777, P. aspera Roding, 1798, and P. vulgata L. 1758. Comparisons with N.W. Europe provide evidence of distinct latitudinal trends in the population dynamics and reproductive biology of these species.
