1. Reciprocal cross infection of sticklebacks with the diphyllobothriidean cestode Schistocephalus solidus reveals consistent population differences in parasite growth and host resistance

Gasterosteidae; Schistocephalus; antagonists; coevolution; cross infection; hosts; hybrids; nitric oxide; phenotype; population size; reciprocal crosses; sympatry; tapeworms; virulence
Abstract:
... BACKGROUND: In host-parasite evolutionary arms races, parasites are generally expected to adapt more rapidly, due to their large population sizes and short generation times. There exist systems, though, where parasites cannot outpace their hosts because of similar generation times in both antagonists. In those cases concomitant adaptation is expected. METHODS: We tested this hypothesis in the thre ...

Abstract:
... Comparative studies of genetic diversity and population structure can shed light on the ecological and evolutionary factors that influence host–parasite interactions. Here we examined whether geography, time and genetic variation in Alaskan three‐spined stickleback (Gasterosteus aculeatus Linneaus) hosts shape the population genetic structure of the diphyllobothridean cestode parasite Schistocepha ...

3. Solo Schistocephalus solidus tapeworms are nasty

Subject:
Gasterosteus aculeatus; Schistocephalus; body condition; energy; intermediate hosts; latitude; tapeworms; virulence
Abstract:
... Trophically transmitted parasites must trade-off own growth on one hand and energy drain from the intermediate host on the other hand, since killing the host before transmission to the next host is a dead end for both parasites and hosts. This challenge becomes especially intriguing when multiple parasites find themselves within the same individual host. The tapeworm Schistocephalus solidus may ga ...

4. Experimental parasite community ecology: intraspecific variation in a large tapeworm affects community assembly

Gasterosteus aculeatus; Schistocephalus; Trematoda; cages; community structure; cross immunity; energy; field experimentation; fish; foraging; immune response; interspecific competition; intraspecific variation; lakes; tapeworms
Abstract:
... Non‐random species associations occur in naturally sampled parasite communities. The processes resulting in predictable community structure (e.g. particular host behaviours, cross‐immunity, interspecific competition) could be affected by traits that vary within a parasite species, like growth or antigenicity. We experimentally infected three‐spined sticklebacks with a large tapeworm (Schistocephal ...

Abstract:
... Aquatic environments are especially susceptible to anthropogenic chemical pollution. Yet although knowledge on the biological effects of pollutants on aquatic organisms is increasing, far less is known about how ecologically-important interspecific interactions are affected by chemicals. In particular, the consequences of anthropogenic pollution for the interaction of hosts and parasites are poorl ...

6. Timing of Infections in the Threespine Stickleback (Gasterosteus aculeatus) by Schistocephalus solidus in Alaska

Abstract:
... This study provides direct evidence for the timing of infections by Schistocephalus solidus in the threespine stickleback (Gasterosteus aculeatus) of south-central Alaska. Young-of-the-year fish in Cheney Lake were infected during their first summer within a few months after hatching in May–June. Infections appear to continue under ice cover on the lake during the subsequent fall and winter. Few, ...

7. The Effect of Salinity on Egg Development and Viability of Schistocephalus solidus (Cestoda: Diphyllobothriidea)

Abstract:
... Schistocephalus solidus plerocercoids commonly infect three-spined stickleback Gasterosteus aculeatus populations in brackish and freshwaters, but infections are typically absent from marine populations. Here we provide an experimental test of the salinity tolerance of S. solidus eggs, to determine the role of salinity in limiting the distribution of infection in coastal zones. We find that S. sol ...
