The systematics and zoogeography of Gyrodactylus from gasterosteid fishes (Apeltes quadracus, Culaea inconstans, Pungitius pungitius, Gasterosteus aculeatus, and G. wheatlandi) in North America were examined through a study of museum-held specimens and fresh material collected from localities across Canada. Six species are considered specific to these fishes, namely: G. alexanderi Mizelle and Kritsky, 1967, G. avalonia Hanek and Threlfall, 1969 (syn. G. lairdi Hanek and Threlfall, 1969, G. memorialis Hanek and Threlfall, 1969, G. terranovae Hanek and Threlfall, 1969), G. canadensis Hanek and Threlfall, 1969, G. cameroni Hanek and Threlfall, 1970, G. eucaliae lkezaki and Hoffman, 1957, and an unidentified species resembling G. pungitii Malmberg, 1964. The fauna has striking morphological similarities to that parasitizing the same host fishes in Eurasia. In fact, G. avalonia, G. canadensis, and the unconfirmed species are considered sister species to G. arcuatus Bychowsky, 1933, G. branchicus Malmberg, 1964, and G. pungitii, respectively. The match-ups are considered to have evolved from three lineages that parasitized G. aculeatus and P. pungitius prior to Pleistocene dispersal that resulted in these fishes and their parasites extending over much of the northern hemisphere. Gyrodactylus cameroni from A. quadracus is probably of North American origin and a sister species of G. avalonia. Gyrodactylus alexanderi from Pacific coast G. aculeatus and G. eucaliae from C. inconstans in the continent's central region have ties with a Pacific lineage. The parasites' geographical distributions and possible evolutionary histories since Pleistocene glaciation are discussed.

The taxonomy of Gyrodactylus species parasitizing captive goldfish (Carassius auratus (L.)) in North America is examined through study of museum-held specimens and fresh material collected in Nova Scotia. Evidence suggests at least two species are present. One is G. gurleyi Price, 1937, which the study redescribes from Texan syntypes and identifies on goldfish in Nova Scotia. A second species occurring in the Nova Scotian samples had a striking resemblance to G. kobayashii but this identification was not confirmed. Both G. gurleyi and the unidentified species are compared with species parasitizing goldfish in the Far East. The study concludes that the species studied probably arrived in North America with host shipments and that all previous reports of G. elegans Nordmann, 1832 and its supposed subspecies from goldfish in North America are incorrect identifications.

The diet of the black-crowned night heron (Nycticorax nycticorax) feeding in June and July along the southern shore of the St. Lawrence Estuary was composed primarily of the threespine stickleback Gasterosteus aculeatus. Three other sticklebacks, G. wheatlandi, Pungitius pungitius, and Apeltes quadracus occur in areas where the birds feed but were not eaten. It is suggested that differential predation on G. aculeatus may diminish interspecific competition for nest sites where the four stickleback species co-occur on the breeding grounds.

Morphological and morphometric comparisons among adult and glochidial unionids from two Nova Scotian locations showed that Anodonta implicata, A. cataracta cataracta, A. c. fragilis, Elliptio complanatus, and Lampsilis radiata radiata were present. Gravidity studies suggested that fully developed glochidia occur from September to May in Anodonta marsupia, for only 5–6 weeks in June and July in E. complanatus, and perhaps at least from spring to early fall in L. r. radiata. Seven of 12 fish species sampled bore glochidia, which were identified in five host species by comparisons of their shapes and dimensions with those of glochidia from adult clams. Results were as follows: A. c. cataracta in Catostomus commersoni in June only, A. implicata or A. c. cataracta in Gasterosteus aculeatus in May and June, Anodonta sp. in Apeltes quadracus and Pungitius pungitius in June, and E. complanatus in Fundulus diaphanus in June and July. Thus, no relationships between gravidity periods of adult clams and infestation periods of their fish hosts by their glochidia were evident for species of Anodonta.

Relative Quality

Whether learning primarily reflects general processes or species-specific challenges is a long-standing matter of dispute. Here, we present a comprehensive analysis of public information use (PI-use) in sticklebacks (Gasterosteidae). PI-use is a form of social learning by which animals are able to assess the relative quality of resources, here prey patches, by observing the behaviour of others. PI-use was highly specific with only Pungitius and their closest relative Culaea inconstans showing evidence of PI-use. We saw no effects of ontogenetic experience upon PI-use in Pungitius pungitius . Experiments with live demonstrators and animated fish revealed that heightened activity and feeding strikes by foraging conspecifics are important cues in the transmission of PI. Finally, PI-use was the only form of learning in which P. pungitius and another stickleback, Gasterosteus aculeatus differed. PI-use in sticklebacks is species-specific and may represent an ‘ecological specialization’ for social foraging. Whether this reflects selection on perception, attentional or cognitive processes remains to be determined.

The salinity tolerance of brook sticklebacks, Culaea inconstans, freshwater ninespine sticklebacks, Pungitius pungitius, and freshwater fourspine sticklebacks, Apeltes quadracus, was studied and compared with the tolerance of Pimephales promelas, Notemigonus crysoleucas, and Umbra limi by increasing the salinity in steps of 10% seawater (3.5‰) at regular intervals. Culaea had a significantly lower salinity tolerance than Pungitius and Apeltes but had a significantly higher salinity tolerance than Pimephales, Notemigonus, and Umbra. Culaea recovered when returned to fresh water after an abrupt transfer to 100% seawater for 1.75 h or less. In Culaea, temperature had an effect on salinity tolerance but neither light duration nor acclimation in 20% seawater could be shown to have any effect. Apeltes had a significantly higher salinity tolerance than Pungitius at 8 °C but not at 16 °C. At 16 °C most feeding and fanning activity ceased at 60%, 80%, and 110% seawater, in Culaea, Pungitius, and Apeltes, respectively. In the Gasterosteidae the order of decreasing salinity tolerance and increasing utilization of the freshwater habitat is as Follows: Spinachia, Apeltes, Gasterosteus, Pungitius, and Culaea.

Neolebouria tinkerbellae n.sp. (Trematoda: Opecoelidae) is described from specimens obtained from experimental infections in Platichthys stellatus (Pallas), Gasterosteus aculeatus Linnaeus, and Leptocottus armatus Girard. The metacercarial stage occurs in the heart muscle of Pandalus jordani Rathbun (smooth pink shrimp) from the Pacific coast of Canada and forms a translucent white cyst. A second, unidentified species of metacercaria found in P. jordani forms a cyst surrounded by a brown pigmented layer in the somatic musculature. Both metacercariae are described.

The genetic relationships between four species of sticklebacks, Gasterosteus aculeatus Linneaus form trachurus, Gasterosteus wheatlandi Putnam, Pungitius pungitius (Linneaus), and Apeltes quadracus (Mitchill) were estimated by a locus-by-locus analysis of interspecific allozyme variation as well as by a band-counting analysis of soluble proteins in muscle. The locus-by-locus data was analysed both by a qualitative cladistic analysis and by a quantitative phenetic analysis. Both the locus-by-locus analysis and the band-counting analysis generated phylogenies which concord with the previously established relationships among these species. Our analyses indicate that these species have diverged considerably with a genetic identity of only 0.37 between the two congeneric species.
