Abstract

V originále

Co-existence among potentialy cpompeting species can be favoured by niche specialisation and/or by reducing the overall intensity of competition via aggregated utilisation of fragmented resources. Comparative analysis showed that parasite abundance is positively correlated with niche breadth. This result gives some support to niche segregation by specialisation. NIche size was negatively correlated with both intraspecific and interspecific aggregation. No relationship have been found between an increase of interspecific aggregation with an increase of niche overlapping, which suggests that competition may play little role. A parsimony analysis of the evolution of gill distribution indicates a change in one parameter of the niche (arch, segment and/or area) at each branching event.
