Some Biogeographers, Evolutionists And Ecologists: Chrono-Biographical Sketches, Charles H. Smith, Joshua Woleben, Carubie Rodgers

DLPS Faculty Publications

Each name in the following list of naturalists is linked to a corresponding capsule "chrono-biographical" sketch of that individual prepared by the authors. Coverage extends from approximately 1950 backward in time as far as the eighteenth century; figures from all over the world are included (though there is admittedly a decided Anglo-American bias). The target subject here is biogeography, but this being a broad field there are many persons on the list who are better known as climatologists, zoologists, botanists, ecologists, oceanographers, paleontologists, etc.--in other words, who made their main reputations in cognate disciplines.

Ecology And Relationships Of Rhabdias Spp. (Nematoda: Rhabdiasidae) From North American Amphibians And Reptiles, Gabriel J. Langford

School of Biological Sciences: Dissertations, Theses, and Student Research

Lungworms of the cosmopolitan genus Rhabdias (Nematoda: Rhabdiasidae) are among the most common parasites of amphibians and squamate reptiles. The life cycles, life histories, host specificities, and evolutionary relationships of Rhabdias spp. were studied through examination of their free-living and parasitic stages in amphibians and reptiles. This study found free-living development of anuran lungworms was primarily limited to heterogonic reproduction, whereas snake lungworms primarily reproduced homogonically. Infective anuran lungworms penetrated the skin of frogs and toads; in contrast, snake lungworms penetrated snake esophageal tissue during per os infections. Our molecular phylogeny strongly supported separate clades for anuran and snake lungworms, …

Areographic Representation Of Faunal Characteristics Through A "Second Order" Relational Approach, Charles H. Smith

DLPS Faculty Publications

Areographic analysis has traditionally depended on primary data consisting of location-specific tallies of presence or absence of given forms. In the present work, an alternate manner of representing distributions is suggested. Regional units are first established, and presence and absence of the forms under consideration in these units is noted. The relation of the biota at any given point location to all others is then established through examination of the former's characteristics of inclusion in the latter. This is accomplished by detailing regional level trends of inclusion and setting up a "second-order" distribution of associations. Two kinds of descriptive information …
