A Fresh Look At The Taxonomy Of Midcontinental Sandhill Cranes, Douglas H. Johnson, Jane E. Autin, Jill A. Shaffer

Proceedings of the North American Crane Workshop

The midcontinental population of sandhill crane (Grus canadensis) includes about 500,000 birds and provides valuable recreational crane-watching and hunting opportunities in Canada and the United States. It comprises three subspecies, one of which (G. c. rowani) was of uncertain taxonomic status and another of which (G. c. tabida) merited protection from excessive harvest due to its small population size. We obtained measurements of cranes used by Johnson and Stewart (1973) and additional crane specimens to 1) evaluate the subspecies designation of midcontinental sandhill cranes and 2) to seek improved methods for classifying cranes from …

Morphological And Molecular Characterization Of Meloidogyne Mayaguensis Isolates From Florida, J. Brito, Thomas O. Powers, P. G. Mullin, Florida Department Of Agriculture And Consumer Services N., D. W. Dickson

Department of Plant Pathology: Faculty Publications

The discovery of Meloidogyne mayaguensis is confirmed in Florida; this is the first report for the continental United States. Meloidogyne mayaguensis is a virulent species that can reproduce on host cultivars bred for nematode resistance. The perineal patterns of M. mayaguensis isolates from Florida show morphological variability and often are similar to M. incognita. Useful morphological characters for the separation of M. mayaguensis from M. incognita from Florida are the male stylet length values (smaller for M. mayaguensis than M. incognita) and J2 tail length values (greater for M. mayaguensis than M. incognita). Meloidogyne mayaguensis values for …

Review Of The Genus Acrobolbia With Remarks On Its Classification, And A Key To The World Genera Of Cyclocephalini (Coleoptera: Scarabaeidae: Dynastinae), Mary Liz Jameson, Brett C. Ratcliffe, Vladislav Maly

University of Nebraska State Museum: Entomology Papers

The monotypic South American scarab genus Acrobolbia Ohaus, 1912 is reviewed and transferred to the tribe Cyclocephalini (Coleoptera: Scarabaeidae: Dynastinae). It was formerly placed in the subtribe Acrobolbiina (Rutelinae: Rutelini) or subtribe Oryctomorphina (Dynastinae: Pentodontini), depending on the author. We discuss characters that warrant transfer, redescribe the genus (including the first description of a female), and briefly discuss natural history of A. macrophylla Ohaus, 1912. We include a key to males and females of all 14 genera of Cyclocephalini.

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

A new microsporidian species, Tuzetia weidneri sp. n. , is described from the skeletal muscle of the decapod crustaceans Litopenaeus setiferus and Farfantepenaeus aztecus. Fresh spores are pyriform, measuring 3.1 x 2.3 µm. All stages have unpaired nuclei. Meronts lie in direct contact with degenerate host cell cytoplasm but produce numerous small blisters at the surface. Multinucleate meronts divide by constriction into groups or chains of uninucleate products. Sporogony is initiated by deposition of a dense surface coat on the plasma membrane of uninucleate or multinucleate stages and fusion of blisters to enclose the sporont in a sporophorous vesicle …

Worms, Nematoda, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Nematodes are the most speciose phylum of metazoa on earth. Not only do they occur in huge numbers as parasites of all known animal groups, but also they are found in the soils, as parasites of plants, and in large numbers in the most extreme environments, from the Antarctic dry valleys to the benthos of the ocean. They are extremely variable in their morphological characteristics, with each group showing morphological adapta­tions to the environment that they inhabit. Soil-dwelling forms are extremely small; many marine species have long and complex setae; and parasitic species man­ifest amazingly great reproductive potential and large …

Molecular Phylogeny Of Clade Iii Nematodes Reveals Multiple Origins Of Tissue Parasitism, Steven A. Nadler, R. A. Carreno, H. Mejía-Madrid, J. Ullberg, C. Pagan, R. Houston, Jean-Pierre Hugot

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Molecular phylogenetic analyses of 113 taxa representing Ascaridida, Rhigonematida, Spirurida and Oxyurida were used to infer a more comprehensive phylogenetic hypothesis for representatives of ‘clade III’. The posterior probability of multiple alignment sites was used to exclude or weight characters, yielding datasets that were analysed using maximum parsimony, likelihood, and Bayesian inference methods. Phylogenetic results were robust to differences among inference methods for most high-level taxonomic groups, but some clades were sensitive to treatments of characters reflecting differences in alignment ambiguity. Taxa representing Camallanoidea, Oxyurida, Physalopteroidea, Raphidascarididae, and Skrjabillanidae were monophyletic in all 9 analyses whereas Ascaridida, Ascarididae, Anisakidae, Cosmocercoidea, …

The Rdna Internal Transcribed Spacer Region As A Taxonomic Marker For Nematodes, Thomas O. Powers, T. C. Todd, A. M. Burnell, P. C. B. Murray, C. C. Flemming, Allen L. Szalanski, B. A. Adams, T. S. Harris

Department of Plant Pathology: Faculty Publications

The ITS region from a wide taxonomic range of nematodes, including secernentean and adenophorean taxa, and free-living, entomopathogenic, and plant-parasitic species, was evaluated as a taxonomic marker. Size of the amplified product aided in the initial determination of group membership, and also suggested groups that may require taxonomic reevaluation. Congeneric species often displayed identically sized ITS regions, but genera such as Pratylenchus and Tylenchorhynchus had species with large differences in size. ITS heterogeneity in individuals and populations was identified in several nematode taxa. PCR-RFLP of ITS1 is advocated as a method of taxonomic analysis in genera such as Helicotylenchus that …

The Internal Transcribed Spacer Region Of Belonolaimus (Nemata: Belonolaimidae), T. Cherry, A. L. Szalanski, T. C. Todd, Thomas O. Powers

Department of Plant Pathology: Faculty Publications

Belonolaimus isolates from six U.S. states were compared by restriction endonuclease digestion of amplified first internal transcribed spacer region (ITS1) of the nuclear ribosomal genes. Seven restriction enzymes were selected for evaluation based on restriction sites inferred from the nucleotide sequence of a South Carolina Belonolaimus isolate. Amplified product size from individuals of each isolate was approximately 700 bp. All Midwestern isolates gave distinct restriction digestion patterns. Isolates identified morphologically as Belonolaimus longicaudatus from Florida, South Carolina, and Palm Springs, California, were identical for ITS1 restriction patterns. The correlation between ITS1 restriction patterns and the distribution of B. longicaudatus isolates …

Critical Comment: Designation And Curatorial Management Of Type Host Specimens (Symbiotypes) For New Parasite Species, Jennifer K. Frey, Terry L. Yates, Donald Duszynski, William L. Gannon, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The accurate identification of a host organism is an important component in the taxonomic recognition of a new species of parasite. Correct identification, curatorial management, and safekeeping of the host specimen from which a parasite type specimen is collected is also desirable. We recommend that the host from which the type of a new parasite species is described should be designated as a symbiotype.

Génétique Systematique Et Des Trichinella [Table Ronde] = Genetics And Systematics Of Trichinella [Round Table], K. D. Murrell, J. Ralph Lichtenfels, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Up to the present time, the existence of two species in the genus Trichinella has been accepted by most workers. The proliferation of isolates and the definition of numerous genetic populations have caused considerable confusion in recent years for taxonomists and others concerned with these nematodes. The application of the biological species-concept to nematodes of the genus Trichinella has been difficult, but the recent investigations of Dr. E. Pozio and coworkers at the Trichinella Reference Center (Laboratory of Parasitology, Istituto Superiore di Sanita, viale Regina Elena, 299-00161 Rome, Italy) have provided new information on numerous isolates from localities worldwide.
