The use of ecological terms in parasitology (report of an ad hoc committee of the American Society of Parasitologists)
TLDR
In this paper, an ad hoc committee was established to establish working definitions of a few terms used and misused by parasitological ecologists as a guide for authors submitting papers to The Journal of Parasitology.Abstract:
In February 1981, ASP President Elmer Noble on recommendation from the Editor, Austin Maclnnis, appointed an ad hoc committee \"to establish working definitions of a few terms used and misused by parasitological ecologists\" as a guide for authors submitting papers to The Journal of Parasitology. Appointed to the committee were Drs. Gerald Esch, John Holmes, Armand Kuris, Gerhard Schad, and Leo Margolis (Chairman). As a starting point the committee examined the recommendations (Margolis et al., 1982) prepared by a similar committee established by the Parasitology Section of the Canadian Society of Zoologists. The Canadian Committee concerned itself only with terms required to express concepts related to the number of hosts in a sample infected with a particular species of parasite, and to the number of individuals of a particular parasite in each host in a sample. As noted below the present committee also dealt with several other ecological terms that are not now being used in a consistent manner in parasitological literature. The following are the committee's recommendations, annotated as required:read more

Seasonal occurrence of Lernaea cyprinacea on fishes in Belews Lake, North Carolina.
TL;DR: Monitoring of fishes in Belews Lake, North Carolina found differences in parasite prevalence may be due to the host habitats, and infection levels do not appear to be related to the size of the host.

Helminth parasites of the digestive tract of the harbour porpoise Phocoena phocoena in Danish waters: a comparative geographical analysis
TL;DR: The geographical analysis suggested the presence of a strong local influence determining the helminth fauna, the cestode Diphyllobothrium stemmacephaluni being the only species which could be considered as a specialist of the harbour porpoise.

Co-existence of congeneric species of acanthocephala: Acanthocephalus lucii and A. anguillae in eels Anguilla anguilla in Ireland.
C. R. Kennedy,C. Moriarty +1 more
TL;DR: Congeneric species of acanthocephalans can co-exist in apparently stable equilibrium in fish as predicted and without any evidence of interactions, but it is still considered that exploitation competition between the species may be occurring in eels.

Covariation of parasite intensities in willow ptarmigan, Lagopus lagopus L.
Per R. Holmstad,Arne Skorping +1 more
TL;DR: Intensities of different parasites in individual hosts were found to be more similar than expected by chance, and Parasite intensities tended to covary inindividual hosts, and this covariation became more pronounced when only microparasites and the most abundant macroparAsites were analysed.

Anisakid parasites of two forkbeards (Phycis blennoides and Phycis phycis) from the eastern Mediterranean coasts in Tunisia
TL;DR: Clear patterns were observed for P. blennoides and P. phycis species, with prevalence and mean intensity of all the anisakid species peaking in spring and summer, when the data were grouped seasonally.

Niche, Habitat, and Ecotope
TL;DR: The confusion comes from use of the same word, "niche," for different concepts, which makes "'niche'" synonymous with "'habitat,'" for the present, the "'hab itat + niche" concept.

An Analysis of the Relationship Between Stress and Parasitism
TL;DR: The impact of stress upon the dynamics of host and parasite populations is varied and the varied response to stressor input at the individual, population and ecosystem levels is dictated by the capacity for adaptability present at each level.

Natural food and feeding in the commercial sand crab Portunus pelagicus Linnaeus, 1766 (Crustacea : Decapoda : Portunidae) in moreton bay, queensland
TL;DR: Diet composition changes little with size of crab although within broad taxonomic groups e.g. the Gastropoda, prey species change with sizeOf crab, diet did not vary seasonally for juvenile P. pelagicus in intertidal areas.
