Systematic Relationships Of Natalid And Furipterid Bats, Based On Hyoid Morphology (Chiroptera: Natalidae And Furipteridae), Kosha N. Baxi '01
Systematic Relationships Of Natalid And Furipterid Bats, Based On Hyoid Morphology (Chiroptera: Natalidae And Furipteridae), Kosha N. Baxi '01
Honors Projects
Themusculature of the hyoid regions of two species of bats (Order Chiroptera) from two separate families, Natalidae and Furipteridae, were examined using standard microscopic dissection techniques. Morphological variation was described and characters were scored and entered into the computer program PAUP, Phylogenetic Analysis Using Parsimony, along with characters of families previously examined by Griffiths. Cladistic analysis revealed support for the placement of Natalidae and Furipteridae together within the Superfamily Nataloidea, along with the families Thyropteridae and Myzopodidae, as recently proposed by Simmons (1998). The inclusion of Myzopodidae is surprising from a geographical standpoint. Myzopodids are endemic to Madagascar, while thyropterids, …

Neotropical Nectar-Feeding Bats (Family Phyllostomidae) Revisited: Lingual Data Support A Recently-Proposed Molecular Phylogeny, Shawn De La Mar '01

From the early 1900s to the 1970s, all New World nectar-feeding bats were classified under the subfamily Glossophaginae. During the last few decades of the 20th century, however, several analyses supported the hypothesis that this taxon was an unnatural grouping. T. A. Griffiths (1982) proposed creating a new subfamily, the Lonchophyllinae, which would include Lonchophylla, Lionycteris, and Platalina, three genera formerly included in the Glossophaginae. This proposal raised significant controversy. A recent molecular study by R. J. Baker and colleagues (2000) examined the RAG2 gene DNA sequence in a large number of bats in the family Phyllostomidae, including Lonchophylla, Lionycteris, …
Lipid Biochemistry Of House Wren Egg Yolk And Possible Effects On Incubation Period, Brian J. Payne '01
Lipid Biochemistry Of House Wren Egg Yolk And Possible Effects On Incubation Period, Brian J. Payne '01
Honors Projects
House Wrens (Troglodytes aedon) are distributed throughout North and South America. As has been observed in many avian species, populations of House Wrens in the tropics have longer egg incubation periods than populations in temperate regions. The purpose of this study was to characterize incubation periods of a temperate population of House Wrens and to conduct a preliminary chemical analysis of the yellow and white yolk layers of House Wren eggs. The eggs were collected from a breeding population in Central Illinois from June-August 2000. Avian yolk is composed of yellow and white components, which are laid down in alternating …
