TY - JOUR ID - 344687 AU - Šimková, Andrea - Gelnar, Milan - Desdevises, Yves - Morand, Serge PY - 2000 TI - Co-existence of nine ectoparasites (Dactylogyrus: Monogenea) parasitising the roach (Rutilus rutilus): history and present ecology JF - International Journal for Parasitology VL - 30 IS - - SP - 1077 EP - 1077 PB - Elsevier Science SN - 00207519 KW - Dactylogyrus KW - Monogenean KW - species co-existence aggregation model KW - comparative analysis N2 - 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. ER -
