Manifestations of infectious disease may represent host adaptations to avoid or reduce the effects of infection on host fitness, parasite manipulations that benefit the pathogen's fitness, or nonadaptive side effects of parasitism. Threespine stickleback fish (Gasterosteus aculeatus) from Alaska and the cestode macroparasite Schistocephalus solidus provide an excellent system for study of the effects of parasitism on host egg size because females in populations there are capable of producing… 
Evolutionary significance of fecundity reduction in threespine stickleback infected by the diphyllobothriidean cestode Schistocephalus solidus.
TLDR
The findings obtained for this population are consistent with the hypothesis of simple nutrient theft; however, populations of S. solidus in other regions may manipulate host energy allocation.
The stickleback–Schistocephalus host–parasite system as a model for understanding the effect of a macroparasite on host reproduction
TLDR
Using the trophic transmitted Schistocephalus as a model, the suite of traits expressed in hosts of trophically transmitted parasites should be systematically investigated to develop a complete understanding of the system.
Effect of the cestode macroparasite Schistocephalus pungitii on the reproductive success of ninespine stickleback, Pungitius pungitius
TLDR
The results of this study support the theoretical prediction that S. pungitii is a parasitic castrator, as the fitness of the majority of infected female ninespine stickleback was apparently reduced to zero, and there may be a similar effect among themajority of male nines Pine Stickleback.
Are solo infections of the diphyllobothriidean cestode Schistocephalus solidus more virulent than multiple infections?
TLDR
Investigating the impact of the diphyllobotriidean cestode Schistocephalus solidus on the body condition and clutch size of threespine stickleback Gasterosteus aculeatus and the growth of larval parasites in host fish found infections have an increasingly negative impact on measures of host fitness with greater intensity.
Fecundity compensation in the three-spined stickleback Gasterosteus aculeatus infected by the diphyllobothriidean cestode Schistocephalus solidus
TLDR
Fertility compensation, an adaptive non-immunological host defence, is demonstrated in the three-spined stickleback fish infected by the diphyllobothriidean cestode Schistocephalus solidus, revealing a trade-off between egg mass and egg number consistent with the fecundity compensation hypothesis.
Fecundity compensation and fecundity reduction among populations of the three-spined stickleback infected by Schistocephalus solidus in Alaska
TLDR
Vum mass of host females who are functionally being starved through nutrient theft seems to be more readily influenced by parasitism and, therefore, decreased before clutch size is reduced, consistent with expectations based on the biology of and effect of feeding ration on reproduction in stickleback females.
Castration of Female Ninespine Stickleback by the Pseudophyllidean Cestode Schistocephalus pungitii: Evolutionary Significance and Underlying Mechanism
TLDR
It is found that inhibition of reproduction in ninespine stickleback occurs in small fish before the size of sexual maturity and is not instantaneous, and castration was observed in lightly and heavily infected adult-size hosts.
Reproductive potential of Schistocephalus solidus-infected male three-spined stickleback Gasterosteus aculeatus from two U.K. populations.
TLDR
The results support the findings of recent studies showing that the effects of S. solidus on host reproduction are unlikely to be uniform across G. aculeatus populations, as well as paralleled by a more limited effect of infection on physiological indicators of development, condition and general health.

Virulence of the cestode Schistocephalus solidus and reproduction in infected threespine stickleback, Gasterosteus aculeatus.
TLDR
It is found that substantial levels of parasitic infection co-occurred with the stickleback reproductive period, and Chi-squared analyses of individual samples suggested that in May, infected females were as capable of producing clutches of eggs as uninfected females but in June, S. solidus inhibited the production of eggs.
Some effects of the cestode (Schistocephalus solidus) on reproduction in the threespine stickleback (Gasterosteus aculeatus): Evolutionary aspects of a host-parasite interaction
TLDR
The effects of Schistocephalus on reproduction in Gasterosteus reached a peak in June and declined sharply through July and August, whereas over 40% of the sexually mature but nongravid females were infected over the entire breeding season.
Body condition and reproductive status in sticklebacks exposed to a single wave of Schistocephalus solidus infection
TLDR
Nuptial coloration, kidney hypertrophy and testes size wereunimpaired in these mature infected males, but whether they were capable of successful reproduction remains debatable.
The Effect of Schistocephalus Solidus (Cestoda: Pseudophyllidea) On the Foraging and Shoaling Behaviour of Three-Spined Sticklebacks, Gasterosteus Aculeatus
TLDR
Experimental work on the shoaling decisions of S. solidus-infected sticklebacks supports the manipulation hypothesis of parasite transmission, and behavioural modification is discussed in the context of this hypothesis.
Infectivity of plerocercoids of Schistocephalus solidus (Cestoda: Ligulidae) and fecundity of the adults in an experimental definitive host, Gallus gallus.
TLDR
The average egg output was predicted by the final adult dry weight and to a lesser extent by the proportion of weight lost in the transition from plerocercoid to adult, but not by the absolute weight loss.
Infections of the three-spined stickleback, Gasterosteus aculeatus L., with the plerocercoid larvae of Schistocephalus solidus (Müller, 1776), with special reference to pathological effects.
TLDR
Infections are described of Gasterosteus aculeatus in a pond at Leeds with the plerocercoid larvae of Schistocephalus solidus with some effects of parasitization on the host include gross distension of the body, reduction of liver weight, reduction in packed cell volume of erythrocytes and delay in oocyte maturation.
Phenotypic Manipulation by the Cestode Parasite Schistocephalus solidus of Its Intermediate Host, Gasterosteus aculeatus, the Threespine Stickleback
TLDR
Schistocephalus solidus has been shown to induce dietary stress and alter the respiration, foraging activity, and risk-taking behavior of G. aculeatus, the threespine stickleback, and is unusual among cestodes because it becomes highly developed in its plerocercoid stage.
Effects of Predation Risk and Parasitism on the Feeding Ecology, Habitat Use, and Abondance of Lacustrine Threespine Stickleback (Gasterosteus aculeatus)
TLDR
From 1980 to 1985, a lacustrine population of threespine stickleback was investigated with respect to densities, individual length, distribution, diet, frequency of parasitism by Schistocepbalus solidus, and selective predation by Atlantic salmon.
Variation in female life-history traits among Alaskan populations of the threespine stickleback, Gasterosteus aculeatus L. (Pisces: Gasterosteidae)

TLDR
The freshwater populations showed considerable variation in all life-history traits assessed, and this variation generally corresponded to the ecomorphological classifications, suggesting that morphological and life- history traits may not always respond in the same manner in response to the same selective regime.
