BUCHHOLZ, D.R.*; ESPIRA, A.; BARBER, P; HAYES, T.B.: Juvenile patterns and sexual dichromatism in the endemic African reedfrog family, Hyperoliidae African reedfrogs, containing 19 genera with hundreds of species, are abundantly found in sub-saharan Africa and nearby islands. We have been studying the sexual dichromatism in the ubiquitous genus Hyperolius at multiple hierarchical levels. A […]

Genomic Tools for Molecular Systematics A Molecular Phylogeny of the Mustelidae (Mammalia Carnivora) Inferred from Multiple Sequence-Tagged Sites
KOEPFLI, K-P.*; WAYNE, R.K.: Genomic Tools for Molecular Systematics: A Molecular Phylogeny of the Mustelidae (Mammalia: Carnivora) Inferred from Multiple Sequence-Tagged Sites Sequence-tagged sites (STSs) are PCR-based markers that amplify specific and homologous nuclear genes in virtually all mammalian species and were developed for the purposes of comparative genome mapping. Several characteristics make these markers […]
Early Tetrapod Relationships Revisited
RUTA, M. *; COATES, M.I.; QUICKE, D.L.J.: Early Tetrapod Relationships Revisited A cladistic analysis of early tetrapods (90 taxa; 307 characters) yields 60 most parsimonious cladograms. These differ only in the internal relationships of aistopods and embolomeres, in the relative position of Balanerpeton, trimerorhachoids and more derived temnospondyls, and in the relative position of derived […]
A comparative test of adaptive hypotheses for sexual size dimorphism in lizards
COX, R.M.*; SKELLY, S.L.; JOHN-ALDER, H.B.: A comparative test of adaptive hypotheses for sexual size dimorphism in lizards. Adaptive hypotheses for the evolution of sexual size dimorphism (SSD) in lizards have generally focused on two processes: (1) sexual selection for large male size, which confers an advantage in intrasexual mate competition, and (2) natural selection […]
Web-HUMAN A Comprehensive Systems Physiology Teaching Simulation Is Available On the Web
MEYERS, R.; GEOFFRION, L.: Web-HUMAN: A Comprehensive Systems Physiology Teaching Simulation Is Available On the Web. Prior to web-HUMAN (http://www.skidmore.edu/academics/human) all comprehensive systems physiology computer teaching simulations were hardware and platform dependant. Web-HUMAN makes available to educators the classic HUMAN FORTRAN physiology simulation (author: Tom Coleman) in an updated format via a custom wrapper that […]
Getting beyond the large-class problem Part II Can we better tailor science education to the individual student
HARRIS COTNER, Sehoya; WOODWARD, Denise M; HAYES, C Nelson; CYR, R J: Getting beyond the large-class problem Part II: Can we better tailor science education to the individual student? Introductory biology at Penn State is typically taught in a large (~800+ student), traditional-lecture format. This method is pragmatic but tends to result in a high […]
Getting beyond the large-class problem Part I Can we measure and improve student engagement in introductory biology

Exposing Undergraduates to Statistics in an Introductory Biology Course
MYERS, M.J.*: Exposing Undergraduates to Statistics in an Introductory Biology Course These days, many introductory biology courses include a lab component in which students conduct experiments of their own design. It is not as common for these courses to give students the tools they need (i.e., basic statistical principles) to meaningfully analyze the data they […]
Digital Portfolios Are Required of Biology Majors
STAUB, N.L.*; PAUW, P.G.: Digital Portfolios Are Required of Biology Majors. We are initiating a curriculum that requires students to maintain a digital portfolio of laboratory work. This portfolio links learning throughout the biology curriculum and allows students to develop a sense of ownership of their work. Students are required to save images from inquiry-based […]
The Relationship Between Student Engagement and Student Performance in an Introductory Biology Course that Emphasizes Active Learning
HOESE , W. J.; WEISS, S. L.: The Relationship Between Student Engagement and Student Performance in an Introductory Biology Course that Emphasizes Active Learning We investigated the relationship between student engagement and performance in college introductory biology. We hypothesized that students who are more actively engaged would perform better than those students who were not […]
