Abstract
Changes in the total weight of live clams Pisidium amnicum and the weight of their shells have been studied by comparing uninfected clams with clams infected by trematods Allocreadium crassum, Phyllodistomum folium, and Bunodera spp. The mean total and shell weights of clams infected with A. crassum are significantly lower than those of uninfected clams. The characteristics of clams infected with P. folium and Bunodera spp. are not different from the control, with the exception of the weight of clams infected with Bunodera spp. Clams infected with mature metacercariae of A. crassum possess light and fragile shells that weigh on average three times less than those of uninfected clams (25.6 vs. 74.1 g). The weight of shells of clams with immature metacercariae is not different from that of uninfected clams. The results are analyzed from the viewpoint of the hypothesis of adaptive manipulation of the host phenotype.
期刊介绍：
Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
