Evolution of complex life cycles in helminth parasites
TLDR
It is suggested that complex cycles in helminths without penetrative infective stages evolve by two essentially different processes, depending on where in the cycle a new host is inserted.
Optimal growth strategies of larval helminths in their intermediate hosts
TLDR
The life history strategy (LHS) model predicts an individual's asymptotic size in its intermediate host, with and without competition from conspecific larvae, and suggests that evolution generates a solution that seems cooperative but is actually selfish.
WHEN SHOULD A TROPHICALLY TRANSMITTED PARASITE MANIPULATE ITS HOST?
TLDR
Investigation of evolution of two categories of adaptive host manipulation by trophically transmitted helminths finds that suppression aids survival to the time when establishment in the next host is possible: it is most favorable if it reduces all aspects of host (and hence parasite) mortality.
Cestodes in South American freshwater teleost fishes: keys to genera and brief description of species
Keys to genera of cestodes in South American freshwater teleost fishes are provided, with diagnoses of genera and short descriptions of species. Two new genera are proposed, Chambriella gen.n. for

Principal Diseases of Marine Fish and ShellfishBy Carl J. Sindermann. Pp. x + 369. (Academic Press: London and New York, April 1970.) 163s.
Seasonal occurrence of helminths in freshwater fishes. Part IV. Adult Cestoda, Nematoda and Acanthocephala.
  • J. C. Chubb
  • Biology, Medicine
    Advances in parasitology
  • 1982
TLDR
The chapter focuses on the schemes of classification adopted and reports the seasonal studies of the cestode, nematode, and acanthocephalan adults of various species, related to the major climatic zones of the world.
Competitive Growth Strategies in Intermediate Hosts: Experimental Tests of a Parasite life-History Model Using the Cestode, Schistocephalus solidus
TLDR
Results support the LHS hypothesis: procercoids of a tapeworm may “count” their conspecific competitors in their first intermediate host to harvest its resources strategically until the next step in their complex life cycle.
Seasonal occurrence of helminths in freshwater fishes. Part I. Monogenea.
  • J. C. Chubb
  • Biology, Medicine
    Advances in parasitology
  • 1977
TLDR
This chapter discusses the seasonal occurrence of monogeneans of freshwater fishes and discusses the subclass polyonchoinea of seasonal studies, including order dactylogyridea, order gyrodactylidesa, and order tetraonchidea.
Seasonal Occurrence of Helminths in Freshwater Fishes Part II. Trematoda
TLDR
The chapter relates the seasonal studies on Metacercariae and adult trematodes to the major climatic zones of the world and summarizes the current knowledge in this field and highlights areas where further information should be collected to assist the understanding of the seasonal dynamics of the trematode.
When to Go: Optimization of Host Switching in Parasites with Complex Life Cycles
TLDR
It is shown for the first time that an optimal transfer time between hosts exists for a “model parasite,” the tapeworm Schistocephalus solidus, from its first (copepod) to its second (fish) intermediate host, and that manipulated behavioral changes are adaptive for S. solidus as they maximize parasite fitness.
