TY - JOUR ID - 721473 AU - Loot, Géraldine - Reyjol, Y. - Poulet, N. - Šimková, Andrea - Blanchet, S. - Sovan, Lek PY - 2007 TI - Effects on small weirs on fish parasite communities JF - Parasitology Research VL - 101 IS - 3 SP - 775-489 EP - 775-489 SN - 09320113 KW - fish communities - parasite communities - small weirs N2 - In this study, we examined the impacts of small weirs on the parasite community of gudgeon and toxostome in a medium-sized river. We tested changes on parasite species diversity using indices that capture both richness and abundance characteristics, and we examined parasite community structure with null models (co-occurrence index C score) and a multiple discriminant function analysis (MDFA). Our results showed that parasite community diversity of gudgeon is strongly influenced by weirs with a maximum diversity upstream of the weirs. Weirs also induce change in abundance of gudgeon parasite species particularly during summer. Nevertheless, we obtained that weirs had no effect on the parasite co-occurrence patterns. In addition, similarity indices indicate that the parasite faunas of newly established limnophilic species (roach and bleak) are hostspecific and are rarely transmitted to other fish species. We conclude that fish parasite communities responded in different ways to the presence of impassable weirs, but, in a general tendency, changing environmental conditions induced by weirs may represent an ecological risk.
