The genus Habronema has four valid species, of which only two are properly known. The present study aimed to describe in detail the morphology of Habronema clarki through optical and scanning electron microscopy analyses. Our results showed that the labial morphology of this parasite is closer to H. muscae than to H. microstoma. Even so, the characteristic pseudolabia and the slightly convex border of the dorsal and ventral lips are sufficient to distinguish these nematodes. Additional morphological data are presented, thus contributing to the knowledge on this little known nematode. In addition, this study provides new locality records for this species.

This thesis attempts to comprehend, through the work of Georg Simmel and Ulrich Beck, two distinct phases of modernity through the concept of individualism and individualization processes arising therefrom. A substantial formulation of the concept that remits to the conceptual transposition unscathed from one reality to another is not the main focus of this study. This is about, in advance, two distinct realities, conceptual and comparative examination that aims to weave the points pertaining to echoes - internalized and modified according to the complexity of the historical premises - the thought of Simmel in theoretical perspective of Beck. The forms can be characterized as individualism according to the socio-philosophical mores of Simmel in the intention to understand the forms assumed by individualism in modern history, as well as the derived individualization processes sustained by individual law. Therewith, is intended to transpose the optical analysis of contemporary Ulrich Beck and reap, through conceptual analysis, the points that refer to the influence and continuity of thought of Georg Simmel

The Arnold Shankman Papers consist mainly of photocopies of manuscript collections which Dr. Shankman used for his research and writing. Included are pamphlets, biographical sketches, correspondence and newspaper accounts. Most of the collection relates to the American Civil War, particularly in Illinois, Georgia, and Pennsylvania, but there is material relating to Jewish history, African-Americans and United States foreign relations.

Wetland ecology is a relatively new field that developed from an initial interest in a few direct benefits that wetlands provide to society. Consequently, much early scientific work was stimulated by economic returns from specific wetland services, such as production of peat and provision of habitat for economically valuable wildlife (e.g., waterfowl and furbearers). Over time, societal interest in wetlands broadened, and these unique habitats are now valued for many additional services, including some that bear non market value. Common examples include carbon sequestration, flood reduction, water purification, and aesthetics. The increased recognition of the importance of wetlands has generated a diversity of job opportunities in wetland ecology and management. Despite the increased knowledge base and enhanced job market, I am not aware of any institutions that offer specialty degrees in this new discipline. Indeed, relatively few institutions offer specific wetland ecology classes, with Arnold G. van der Valk and a few of his peers at other universities being notable exceptions.

The spotted paca is the second largest rodent in Brazil, where it is of great economic interestin impoverished regions in view of its prominence as a low-cost source of protein. Littleis known about the morphology of the accessory genital glands of this species. Thus, westudied the position and morphology of the genitals in ten adult male spotted pacas. Theanimals were divided into two groups, five animals were used for fixing of samples in 10%aqueous formaldehyde for macroscopic studies and the other five animals were designatedfor microscopic analysis. These were arranged in pairs and had the vesicular, prostate,coagulating and bulbourethral glands identified, being structured as mucous glands, whichlead into the pelvic urethra. It was concluded that the accessory genital glands found in thepaca are the same as those found in most rodents, showing similar histological aspects
