Attempts to differentiate elaphostrongyline larvae (Nematoda : Protostrongylidae) using guinea pigs (Cavia porcellus) as alternate hosts
(1989)First-and third-stage larvae of Parelaphostrongylus tenuis, P. andersoni and Elaphostrongylus cervi could not be distinguished morphometrically. Third-stage larvae of P. tenuis did develop into recognizable adults ... -
Biology and histopathology of Proteocephalus ambloplitis Liedy, 1887, infecting walleye (Stizostedion vitreum vitreum) and yellow perch (Perea flavescens) in Lake of the Woods, Ontario
(1985)Walleye (Stizostedion vitreum vitreum ) and yellow perch (Perea flavescens ) from Lake of the Woods were examined for parenteral Proteocephalus ambloplitis from May to November, 1982 and 1983. One hundred percent of ... -
Biology of Cystidicola farionis Fischer, 1798 (Nematoda : Cystidicolidae) in salmonid fishes
(1987)Morphological studies, experimental cross-infections and host specificity data suggest that the species of swimbladder nematode which matures in Coregonus clupeaformis, from inland lakes is not distinct from Cystidicola ... -
Biology of rumen flukes (Trematoda: Paramphistomatidae) in moose, Alces alces L., in northwestern Ontario
(1985)Paramphistoines {Parampbistomum sp.) were found in 86% of 160 moose rumens collected from northwestern Ontario at all seasons of the year. All moose older than 2.4 years were infected. The number of flukes per moose ranged ... -
Biology of the gastro-intestinal helminths of woodland and barren-ground caribou (Rangifer tarandus)
(1987)Twenty-one species of helminths were recovered from wild and captive caribou (Rangifer tarandus). Woodland caribou of the Slate Islands, barren-ground caribou of the Beverly herd and captive woodland caribou were parasitized ... -
Characterization of the second internal transcribed spacer (ITS-2)rDNA region among the Elaphostrongylinae (Nematoda:Protostrongylidae)
(2002)Four species of elaphostrongyline nematodes are known to infect cervids in North America. One species, Parelaphostrongylus tenuis, can cause neurologic disease (parelaphostrongylosis) in cervid hosts other than white ... -
Distribution of Angiostrongylus vasorum and Crenosoma vulpis in red foxes (Vulpes vulpes) in Newfoundland, Canada
(2002)Angiostrongylus vasorum, the French heartworm, and Crenosoma vulpis, a lungworm, infect the pulmonary arteries and the bronchi and bronchioles, respectively, o f red foxes (Vulpes vulpes). Both are widespread in Europe, ... -
Ecology of terrestrial gastropods and their response to conifer release treatments in northwestern Ontario
(1995)The primary objective of this study was to document any changes in terrestrial gastropod species richness and density associated with alternative methods of managing competing vegetation on regenerating conifer plantations. ... -
Effects of alternative conifer release treatments on terrestrial gastropods of regenerating spruce plantation
(1997)This study examined changes in terrestrial gastropod densities and species richness associated with alternative methods of managing competing vegetation on regenerating spruce plantations. Data were collected monthly ... -
Factors affecting the distribution and transmission of Elaphostrongylus rangiferi in caribou (Rangifer tarandus caribou) of Newfoundland
(2000)Elaphostrongylus rangiferi is an introduced parasite in caribou (Rangifer tararuhts caribou) of Newfoundland and has caused at least two epizootics of cerebrospinal elaphostrongylosis (CSE), a debilitating, neurologic ... -
Infrapopulation dynamics of Parelaphostrongylus tenuis in white-tailed deer
(1994)White-tailed deer (Odocoileus virginianus), of known age, collected in northeastern Minnesota (n=379) from November 1991 to May 1993 were examined for Parelaphostrongylus tenuis. Prevalence and intensity estimates ... -
Migration and development of Cystidicola spp. (Habronematoidea) in their definitive hosts and the population biology of C. cristivomeri White, 1941 in Salvelinus spp.
(1980)The development of Cystidicola cristivomeri in lake trout, Salvelinus namaycush, and C, farionis in rainbow trout, Salmo gairdneri, is described. The population biology of C. cristivomeri was investigated in lake trout ... -
Morphology and phylogeny of the Elaphostrongylinae : (Nematoda: Protostrongylidae)
(1992)The morphology of elaphostrongyline nematodes parasitizing North American cervids was studied using light and scanning electron microscopy in order to improve previous descriptions that were based exclusively on light ... -
Movements, survival and habitat use by elk (Cervus elaphus) reintroduced to Northwestern Ontario
(2003)Once native to Ontario, eastern elk (Cervus elaphus canadensis) occupied much of the deciduous forest biome of eastern North America. However, increasing human settlement, as well as demands for meat and agricultural ... -
Studies of the biology of swim bladder nematodes, Cystidicola spp. (Habronematoidea)
(1978)The life cycle and larval development of swim bladder nematodes, Cystidicola spp., have been elucidated. C, farionis developed in three species of amphipod. Naturally infected amphipods have been found previously but one ... -
Taxonomic revision of the subfamily Schistorophinae (Nematoda: Acuaroidea) and its North American distribution in waders belonging to the families Charadriidae, Scoloacidae and Recurvirostridae (Aves)
(1984)The subfamily Schistorophinae Travassos, 1918 is revised. Five species of Schistorophus Railliet, 1916 are recognized: (1) longicornis (Hemprich and Ehrenberg in Schneider, 1866) with S. indica (Sanwal, 1952) and ...
