Phylogeography of the plains killifish, Fundulus zebrinus.

Spatial and temporal distribution of the Asian fish tapeworm Bothriocephalus acheilognathi (Cestoda: Bothriocephalidea) in the Rio Grande (Río Bravo del Norte).

Recent collections of the Asian fish tapeworm Bothriocephalus acheilognathi in the Rio Grande have raised concern about the potential impacts on Rio Grande endemic and imperiled fishes. The objectives of this study were to determine distribution and definitive hosts of the Asian fish tapeworm within the Rio Grande drainage and to quantify occurrences and abundances. In total, 1,992 fish spannin...

Myxosoma funduli Kudo 1918 (Protozoa: Myxosporida) in Fundulus kansae: summer epizootiology.

The occurrence and distribution of the myxosporida Myxosoma funduli on the gills of the plains killifish (Fundulus kansae) were investigated; Fundulus kansae is reported as a new host. Host samples from various sites on the South Platte River, Nebraska, were collected during the summer months of 1975 and 1976. The protozoan parasite population was shown to be overdispersed within the host popul...

Dynamics of the Parasite Assemblage of Pimephales promelas in Nebraska

Present theory states that in species-poor assemblages interactions among species are negligible and assemblage structure is a result of host/parasite interactions. A corollary to this theory is that parasite species assemblages should behave as accumulations of multiple-kind items drawn from a population in which only the relative probability of drawing each kind varies. This study was designe...

Comparing Methods of Euthanasia and Gill Culture for Hypoxia Research on the Gulf Killifish, Fundulus grandis

Ecology of the brain trematode Euhaplorchis californiensis and its host, the California killifish ( Fundulus parvipinnis ).

We describe the distribution and abundance of the brain-encysting trematode Euhaplorchis californiensis and its second intermediate host, the California killifish (Fundulus parvipinnis), in 3 estuaries in southern California and Baja California. We quantified the density of fish and metacercariae at 13-14 sites per estuary and dissected 375 killifish. Density (numbers and biomass) was examined ...
