Aspectos quantitativos e morfométricos das infrapopulações de platynosomum illiciens (trematoda: dicrocoeliidae) em paroaria dominicana (passeriformes: emberizidae) do estado da Bahia, Brasil

Abstract

RESUMODurante o estudo dos metazoários parasitos de Paroaria dominicana Linnaeus, 1758 (Passeriformes), quatro infrapopulações de Platynosomum illiciens (Brown, 1901) (Brown, 1901) (Trematoda), parasitic in the liver ducts were collected, with intensity of infection 10, 11, 18 and 36 specimens respectively. Differences between the means of morphometrical values and the total number of eggs were statistically tested. The liver weigh were not significantly correlated with avian total weigh and length, and with the total parasitic abundance. Positive correlations were observed between the size of infrapopulations and the total number of eggs, and between parasite body size and the eggs. size. Negative correlations were observed between parasitic intensity and liver weigh; between the size of infrapopulations and the parasite body size; between total number and the size of eggs and between parasite body size and total number of eggs. These results suggests that host with smaller liver had greater infrapopulations. These greater infrapopulations showed smaller parasite body size and higher size and number of eggs.

The evolution of parasitoid fecundity: a paradigm under scrutiny

“…The influence of Price’s studies also extends beyond parasitoid biology; his writings have been cited in the life‐history literature for a diverse array of other animals – both parasitic and free‐living – including rhombozoans (Furuya et al. 2003), flatworms (Carvalho et al. 2007), molluscs (Boletzky 2003), annelids (Poulin 2001), crustaceans (Timi et al.…”
