Xerox University Microfilms INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round bfack mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understandingof the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

Crites Tony J . Peterle Loren S. Putnam ACKNOWLEDGMENTS A large number of individuals have contributed to my development as a biologist and scholar. Most importantly, Professor John L. Crites has given generously of his spiritual and material wealth to provide an atmosphere in which one joyfully acquires a working knowledge of the discipline of parasitology. Human beings spend their lives adopting various models of behavior. A part of the man that Dr, Crites is can be fqund as a part of this writer. This study would not have been possible without the aid of Dr, L, S. Putnam, Director, Franz Theodore Stone Labora­ tory. The assistance of Dr, M. Miskimen was, likewise, invaluable. The ready assistance offered to a parasitology student working on birds by these two ornithologists is, perhaps, the most telling statement that can be made about these kind people. Over the years, a number of graduate students in parasitology and ornithology have aided me in this study in various ways. Since they are too numerous to acknowledge individually, I wish to recognize their contributions collectively.

  • Urbanization Effects on Carabid Diversity in Boreal Forests
    Eur. J. Entomol. 100: 73-80, 2003 ISSN 1210-5759 Urbanization effects on carabid diversity in boreal forests Stephen J. VENN*, D. Johan KOTZE and Ja ri NIEMELA Department ofEcology and Systematics, Division ofPopulation Biology, PO Box 65 (Viikinkaari 1), FIN-00014, University of Helsinki, Helsinki, Finland Key words. Boreal forest, carabid beetles, urbanization, urban forests, urban green space and urban-rural gradient Abstract. Carabid abundance, species richness and diversity were compared along an urban-rural gradient in Helsinki, Finland. Increased urbanization was found to result in significant reductions in species richness, though the reductions in abundance and diversity were not statistically significant. Forest habitat-specialist species were scarce in rural sites and virtually absent from urban and suburban sites. There was no evidence of higher diversity at intermediate disturbance levels (suburban sites), as predicted by the intermediate disturbance hypothesis. Species with flight ability and the ability to utilize open habitat were more predominant in urban and suburban sites. Flightless species were more predominant in rural and suburban sites. Carabid abundance data were suffi­ cient to reveal the negative impact of urbanization, so similar studies could be conducted in regions where carabid taxonomy is poorly known. Species composition patterns do, however, provide invaluable information. To conclude, if biodiversity is to be main­ tained in urban areas, priority must be given to the provision of those habitat features which are essential for sensitive species, such as decaying wood and wet microhabitats. These must be incorporated into urban green networks in particular, if biodiversity and species other than common generalists are to benefit from them.

  • Somatic Musculature in Trematode Hermaphroditic Generation Darya Y
    Krupenko and Dobrovolskij BMC Evolutionary Biology (2015) 15:189 DOI 10.1186/s12862-015-0468-0 RESEARCH ARTICLE Open Access Somatic musculature in trematode hermaphroditic generation Darya Y. Krupenko1* and Andrej A. Dobrovolskij1,2 Abstract Background: The somatic musculature in trematode hermaphroditic generation (cercariae, metacercariae and adult) is presumed to comprise uniform layers of circular, longitudinal and diagonal muscle fibers of the body wall, and internal dorsoventral muscle fibers. Meanwhile, specific data are few, and there has been no analysis taking the trunk axial differentiation and regionalization into account. Yet presence of the ventral sucker (= acetabulum) morphologically divides the digenean trunk into two regions: preacetabular and postacetabular. The functional differentiation of these two regions is already evident in the nervous system organization, and the goal of our research was to investigate the somatic musculature from the same point of view. Results: Somatic musculature of ten trematode species was studied with use of fluorescent-labelled phalloidin and confocal microscopy. The body wall of examined species included three main muscle layers (of circular, longitudinal and diagonal fibers), and most of the species had them distinctly better developed in the preacetabuler region. In majority of the species several (up to seven) additional groups of muscle fibers were found within the body wall. Among them the anterioradial, posterioradial, anteriolateral muscle fibers, and U-shaped muscle sets were most abundant. These groups were located on the ventral surface, and associated with the ventral sucker. The additional internal musculature was quite diverse as well, and included up to twelve separate groups of muscle fibers or bundles in one species.

Helminths with heteroxenous cycles provide clues for the trophic relationships of definitive hosts, representing important sources of information for assessing niche overlap between males and females of non-dimorphic species. We necropsied 151 rufous-bellied thrushes (Turdus rufiventris) captured in a metropolitan region in southern Brazil to analyze whether the structure of parasite communities is influenced by host sex or age.
