Cuticular Ridge Pattern In Ostertagia Gruehneri And Ostertagia Arctica (Nematoda: Trichostrongyloidea) From Caribou, Rangifer Tarandus, J. Ralph Lichtenfels, P. A. Pilitt, M. Fruetel

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two species of medium stomach worms are common parasites of the caribou, Rangifer tarandus. The two species, Ostertagia gruehneri Skrjabin, 1929, and O. arctica Mitzkewitzsch, 1929, differ so markedly in morphology of the spicules and genital cone that many nematode systematists place them in different genera. Recent studies of similar pairs of species parasitic in other ruminants have provided evidence that such pairs of species may be morphotypes of one species. The two species from caribou are redescribed with emphasis on the pattern of surface cuticular ridges and the structure of the esophagus, characters considered useful for distinguishing species …

Some Helminth Parasites Of Dunlin (Calidris Alpina) And Western Willet (Catoptrophorus Semipalmatus Inornatus) From California, Hilda Lei Ching

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Dunlins and western willets were collected on their winter feeding grounds at Bodega Bay and Bolinas Lagoon, California, during 1986. Six digeneans, eight cestodes, two acanthocephalans, and a new nematode were found in dunlins. Seven digeneans, two cestodes, one acanthocephalan, and the new nematode were found in western willets; four helminths including the new roundworm were common to dunlins. Thominx cecumitis sp. n. differs from other capillarid nematodes with a spinous spicule-sheath in having a short, globular vulvar appendage, peanut-shapcd eggs, a cuticular ball at the posterior tip of the body, narrow lateral alae, and a cuticular genital bursa.

The Morphometrics Of Xiphinema Americanum Sensu Lato In California, John A. Griesbach, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Ten populations of Xiphinema americanum sensu lato (S. l.)from California and two from the eastern United States were studied in a morphometric comparison. Morphometrics were generated by descriptive statistics and a stepwise discriminant analysis (SDA) from nine California field populations, and voucher specimens from a previous California vector study (Hoy, Mircetich & Lownsbery, 1984); identifed as X. californicum. AIso included were greenhouse populations of X. americanum Cobb, 1913 sensu stricto (s. s.) from New York (N.Y.) and X. rivesi Dalmasso, 1969 from Pennsylvania (Pa). SDA canonical plots of individual specimens showed the X. rivesi population …

An Alternative Approach For Evaluating The Efficacy Of Potential Biocontrol Agents Of Weeds. 2. Path Analysis, Dan J. Pantone, William A. Williams, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Path analysis was used to assess the efficacy of the fiddleneck flower gall nematode as a weed biocontrol agent of coast fiddleneck in competition with wheat during two years of field experiments. The path analysis revealed that the number of inflorescences/plant for fiddleneck and the number of heads/plant for wheat were the most important yield components that determine fecundity and seed yield. The density of fiddleneck had a much greater impact on the yield components of fiddleneck than did the density of wheat or the nematode rate of inoculation. The nematode had its greatest negative impact on the number of …

The Phylogeny Of The Cercomeria (Platyhelminthes: Rhabdocoela) And General Evolutionary Principles, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The unified theory of evolution is an expansion of Darwinian theory that asserts that evolution is driven by entropic accumulation of genetic information that is constrained and organized primarily by the genealogical effects of phylogenetic history and developmental integration, and secondarily by ecological effects, or natural selection in its classical mode. Phylogenetic systematic analysis of the 8 major groups of parasitic rhabdocoelous platyhelminths permits empirical macroevolutionary evaluation of these postulates. Of the 131 characters considered, 127 are phylogenetically constrained, and 4 show evidence of 1 case of convergence each. Data from different developmental stages are phylogenetically congruent, despite differences in …

Phylogenetic Relationships Among Genera Of The Tetrabothriidae (Eucestoda), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cladistic analysis of the generic-level relationships within the family Tetrabothriidae was conducted. A single cladogram resulted from evaluation of 28 homologous transformation series representing 41 character states. The genus Tetrabothrius was recognized as plesiomorphic followed by Chaetophallus and Trigonocotyle. The latter was considered as the sister group for the remaining tetrabothriid genera of marine mammals. Anophryocephalus, Strobilocephalus, and Priapocephalus are among the most highly derived genera and are postulated as having close evolutionary affinities. Comparisons to previous explicit hypotheses for relationships among the genera indicated the present analysis was the most efficient phylogenetic statement (consistency index = …

Salsuginus Thalkeni N. Sp. (Monogenea: Ancyrocephalidae) From Fundulus Zebrinus In The South Platte River Of Nebraska, John J. Janovy Jr., Tim R. Ruhnke, Terry A. Wheeler

Molecular Evidence For Inclusion On The Phylum Pentastomida In The Crustacea, Lawrence G. Abele, Won Kim, Bruce E. Felgenhauer

Harold W. Manter Laboratory of Parasitology: Library Materials

The phylogenetic status of the phylum Pentastomida (tongue worms) was considered on the basis of comparison of nucleotide sequences of 18S ribosomal RNA from the pentastome Porocephalus crotali, the branchiuran crustacean fish louse Argulus nobilis, other crustaceans, and representatives of the Annelida, Chelicerata, Myriapoda, and Insecta. Maximum parsimony and invariants (at P < 0.04) analyses support an Argulus/Porocephalus clade, providing strong support for the proposal that tongue worms are highly modified crustaceans closely related to fish lice.

Executive Summary

Biological diversity refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).

There is an ongoing, unprecedented loss of the variety as well as absolute numbers of organisms-from the smallest microorganism to the largest and most spectacular of …

Case Report Of Human Infection With Capillaria Philippinensis, Ching-Yu Chen, Wei-Chuan Hsieh, Tsang-Lie Chen

Harold W. Manter Laboratory of Parasitology: Library Materials

In July 1988, a case of human infection with Capillaria philippinensis, so-called the intestinal capillariasis, was discovered at the National Taiwan University Hospital (NTUH). This is the first case reported in Taiwan.

Capillaria philippinesis is a parasite of fish-eating birds In nature it has a fish-bird life cycle. When human populations disrupt the natural cycle by eating raw fish infected with the larvae of C. philippinensis, they may acquire the disease.

The Phylogenetic Status Of The Ancryocephalidae Bychowsky, 1937 (Monogenea: Dactylogyroidea), Delane C. Kitsky, Walter A. Boeger

Harold W. Manter Laboratory of Parasitology: Library Materials

Phylogenetic analysis of selected subfamily and family taxa within the Dactylogyroidea indicates that the Ancyrocephalidae Bychowsky, 1937, is unnatural. The family contains both poly- and paraphyletic features. The analysis supports the previous elevation of the Pseudomurraytrematinae to family status and suggests that revision of the Ancyrocephalidae is necessary. Two options for revision are provided; that of returning the taxon to subfamily status within the Dactylogyridae is preferred, requiring a change in status of the Heterotesiidae to a subfamily within the Dactylogyridae.

Helminth Parasites Of Northern Spotted Owls (Strix Occidentalis Caurina) From Oregon, Eric P. Hoberg, G. S. Miller, E. Wallner-Pendleton, O. R. Hedstrom

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminth parasites are reported for the first time from northern spotted owls. Seventyone percent of a sample of Strix occidentalis caurina from western Oregon was infected. Nematodes (Porrocaecum depressum, Capillaria falconis, Microtetrameres sp. and Synhimantus hamatus) were the most prevalent parasites although cestodes (Paruterina rauschi) and acanthocephalans (Centrorhynchus conspectus) were also represented. There was an association between components of this helminth fauna and the diet of spotted owls which is dominated by small rodents. The occurrence of P. rauschi rather than P. candelabraria in this geographic region and host-species may provide additional …

A Mimbres Burial With Associated Colon Remains From The Nan Ranch Ruin, New Mexico, Harry J. Shafer, Marrianne Marek, Karl J. Reinhard

Karl Reinhard Publications

The skeletal remains of an adult male associated with desiccated tissue and a coprolite were recovered from an apen-air midden deposit at the NAN Ranch Ruin (LA15049)) a large Mimbres site in Grant County) New Mexico. The find dates to about A.C. 1000-1100. Identifiable macroscopic elements in the caprolite consist offi nely fragmented corn and tiny seed fragments of an unknown plant. High amounts of willow (Salix) and mustard (Brassicaceae) pollen may indicate the ingestion of medicinal plants to combat a deteriorating health condition. The individual was approximately 35 -40 years old at the time of death and suffered from …

Bioarcheological Synthesis For "From The Gulf To The Rio Grande: Human Adaptation In Central, South, And Lower Pecos Texas", Karl Reinhard, Ben W. Olive, D. Gentry Steele

Karl Reinhard Publications

One of the main problems encountered in the review of the bioarcheology of Region 3 has been the limited number of sites where human skeletal material has been adequately recovered and analyzed. In the preceding chapter it was documented that less than 30% of the burials recovered from recorded sites have been reported in published literature. It was further estimated that of the 323 sites with burials, no more than 80 sites have published detailed bioarcheological reports on the burials recovered. Only 50 of these 80 reports provide individual descriptions of each burial which facilitate subsequent analyses and evaluation.

An Alternative Approach For Evaluating The Efficacy Of Potential Biocontrol Agents Of Weeds. 1. Inverse Linear Mode, Dan J. Pantone, William A. Williams, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Methods for evaluating the efflicacy of potential classical biocontrol agents were outlined for a model biocontrol agent-weed-crop system. A proposed biocontrol agent (the fiddleneck flower gall nematode), its weed host (coast fiddleneck), and wheat were used as representative organisms. An additive experimental design (inverse linear model) was used. Regression of the reciprocal of the average plant biomass of each species onto the density of itself and the other plant species yielded competitive indices that measure the competitive ability of the plants. The results of 2 yr of field experiments revealed a dramatic change in the competitive interaction between fiddleneck and …
