fish and their metazoan parasites (multiple sources)
Data on host use by
parasites were obtained from 7 Canadian freshwater systems, either
large lakes or rivers, in which most fish species have been surveyed
for parasites. Only fish species for which at least 5 individuals have
been examined per locality are included, because estimates of parasite
infection level were inaccurate for smaller samples. All species of
internal and external metazoan parasites were considered, which include
the following groups: nematodes, acanthocephalans, cestodes,
trematodes, monogeneans, leeches, copepods and branchiurans. When a
species of internal worm occurred among sampled fish as both larval and
adult forms, the two forms were treated as functionally distinct
species; this convention is justified because larval and adult worms
often have different modes of transmission, infect different fish
species, and different organs within fish.
Two types of data given for
most datasets: prevalence, which describes the proportion of host
individuals harboring a particular parasite species; and intensity of
infection, which describes the average parasite load (number of
individual parasites) per host individual. Prevalence and intensity
data are presented as two separate interaction matrices. In addition,
all datasets include information on the host sample size (number of
host individuals examined for parasites) and one (Cold Lake) also
included an independent estimate of host abundance.
