On The Trail Of The Native Budworm, Kevin Walden

Journal of the Department of Agriculture, Western Australia, Series 4

Native budworm, the worst pest of lupins, is a bit of a uiill-o-the-unsp. Some years the native budworm moths go virtually unnoticed. In others, they appear in plague proportions without warning - in these years, the cost to growers in lost yield runs into millions of dollars.

If an early warning system can be developed to predict the extent of moth flights into lupin crops, and this seems possible, major crop losses could be averted.

The Department of Agriculture has started research to develop a system of predicting the size of spring flights of native budworm moth. We need to …

Historical Ecology As A Research Program, Daniel R. Brooks, Deborah A. Mclennan

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Modern evolutionary biology is the descendant of two theories proposed by Darwin. First, all organisms are connected by common genealogy, and second, the form and function of organisms is closely tied to the environments in which they live. Of these two theories, the role of the first (phylogeny) in evolutionary explanations has been diminishing in some fields, most notably in ecology and ethology. However, the last ten years have witnessed the beginning of a reversal in this trend. With increasing frequency, ecologists (Wanntorp et aI., 1990; Maurer and Brooks, submitted), ethologists (Dobson, 1985; Huey and Bennett, 1987; Mclennan et aI., …

Vertebral Pathology In Prehistoric And Historic Skeletons From Northeastern Nebraska, Karin L. Sandness, Karl J. Reinhard

Karl Reinhard Publications

Vertebral pathology has long been a useful criterion for anthropologists in the assessment of activity patterns, stress, and general health of extinct peoples. This method of analysis, however, has never been applied to the peoples of the Nebraska Great Plains. This study is the first to concentrate on the indigenous Native Americans of this region, examining the spinal pathology present in the prehistoric and historic skeletal remains. Pathology present in the form of spondylolysis, Schmorl's nodes, osteophytosis (degenerative disc disease), and osteoarthritis (degenerative joint disease), provides evidence to suggest differing activity patterns and levels of stress in Plains groups before …

New Species Of Rhabdochona Railliet, 1916 (Nemata: Rhabdochonidae) From Rainbow Trout In California Streams, Armand R. Maggenti, Fawzia Abdel-Rahman, I. Cid Del Prado Vera

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Three new species of Rhabdochona Railliet, 1916 are described and illustrated from Salmo gairdneri Richardson (rainbow trout) in freshwater streams in California: Rhabdochona californiensis n. sp., R. paxmani n. sp., and R. satmonis n. sp. Rhabdochona californiensis n. sp. is characterized by 14 anteriorly directed teeth in the prostome, egg devoid of filaments or floats, male and female tail terminus with a single mucro, left (long) spicule slender with a moderate distended podoid terminal end, spicular ratio 1:3.8. Rhabdochona paxmani n. sp. is characterized by 10 teeth in the prostome, eggs with polar floats, left (long) spicule slender with podoid …

Phylogeny, Historical Biogeography, And Ecology Of Anophryocephalus Spp. (Eucestoda: Tetrabothriidae) Among Pinnipeds Of The Holarctic During The Late Tertiary And Pleistocene, Eric P. Hoberg, Ann M. Adams

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Phylogenetic systematic analyses of Anophryocephalus spp. resulted in a single most-parsimonious cladogram (consistency index: 80%). Cladograms for pinniped hosts (phocids and otariids) and Anophryocephalus spp. were highly incongruent, corroborating a hypothesis for colonization as a dominant determinant of parasite diversification. Phoca (Pusa) spp. in the Atlantic basin are postulated as the initial hosts; range expansion for hosts and parasites into the Pacific basin through the Arctic (ca. 3.0-2.5 million years ago) was followed by radiation of Anophryocephalus spp. among Phoca spp. and subsequent colonization of otariids (Eumetopias jubatus as typical hosts; ca. 2.0 million years ago). Host …

Morphology Of The Synlophe And Genital Cone Of Parostertagia Heterospiculum (Trichostrongylidae) With Comments On The Subfamilial Placement Of The Genus, Eric P. Hoberg, J. Ralph Lichtenfels

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The genus Parostertagia is referred to the Cooperiinae with reference to a suite of shared characters of the synlophe and genital cone postulated as derived homologies for the subfamily. The genus has traditionally been relegated to the Graphidiinae or Ostertagiinae, but unique structural attributes of the synlophe and genital cone indicate close affinities with the Cooperiinae. The synlophe of Parostertagia heterospiculum is characterized by a relatively low number of ridges in the cervical zone (16-20 at the excretory pore), a frontal axis of orientation, sequential increase in ridges posteriorly, lateral addition of ridges, minuscule lateral-most ridges and hypertrophy of specific …

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Baughn M. Bryant Jr

Karl Reinhard Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …

Dan Canyon Burial: A Piii Burial In Glen Canyon National Recreation Area, Steve Dominguez, Karl Reinhard, Kari L. Sandness, Cherie A. Edwards, Dennis Danielson, F. A. Calabrese, Chris Kincaid

Karl Reinhard Publications

The Dan Canyon burial was discovered at a time when the philosophy, ethics, and legislation concerning the study of human remains are in a state of flux. A number of important sensitive issues germane to managers, archeologists, and American Indians are discussed in the introduction. The subsequent analysis provides a detailed scientific account of these remains and a glimpse of a segment of a people's past lifeway while remaining sensitive to the wishes of the American Indians.

The burial and associated grave goods of site 42SA21339 were exposed by wave action in a location frequented by boaters at the Glen …

Microphallus Fonti Sp. N. (Digenea: Microphallidae) From The Red Swamp Crawfish In Southern United States, Robin M. Overstreet, Richard W. Heard, Jeffrey M. Lotz

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of digenean, Microphallus fonti, is described from the red swamp crawfish in Louisiana, USA. It has a small pharynx and a rudimentary gut like M. opacus and possibly related species from crayfishes, but it differs from them by its relatively large male copulatory papilla and a conspicuous metraterm.
