A Hands-On Activity To Introduce The Effects Of Transmission By An Invasive Species, Barbara May
A Hands-On Activity To Introduce The Effects Of Transmission By An Invasive Species, Barbara May
Biology Faculty Publications
This activity engages students to better understand the impact of transmission by invasive species. Using dice, poker chips, and paper plates, an entire class mimics the spread of an invasive species within a geographic region. The activity can be modified and conducted at the K-16 levels.
Quantitative Acoustic Analysis Of The Vocal Repertoire Of The Golden Rocket Frog (Anomaloglossus Beebei), Beth A. Pettitt, Godfrey R. Bourne, Mark A. Bee
Quantitative Acoustic Analysis Of The Vocal Repertoire Of The Golden Rocket Frog (Anomaloglossus Beebei), Beth A. Pettitt, Godfrey R. Bourne, Mark A. Bee
Biology Faculty Publications
This study describes the vocal repertoire of the Guyanan golden rocket frog, Anomaloglossus beebei, a bromeliad specialist with biparental care. Using multivariate analyses of nine call properties, as well as the occurrence of nonlinear phenomena, three signal types were distinguished—advertisement, courtship, and aggressive calls. Although all three call types were composed of a short series of rapidly repeated pulses, advertisement calls were produced at higher amplitudes and had longer pulse durations than both courtship calls and aggressive calls. Courtship calls exhibited lower dominant frequencies than both advertisement and aggressive calls, which had similar dominant frequencies. Aggressive calls had more …
Phylogenetic Reanalysis Of Strauch's Osteological Data Set For The Charadriiformes, Philip C. Chu
Phylogenetic Reanalysis Of Strauch's Osteological Data Set For The Charadriiformes, Philip C. Chu
Biology Faculty Publications
Strauch's (1978) compatibility analysis of relationships among the shorebirds (Charadriiformes) was the first study to examine the full range of charadriiform taxa in a reproducible way. Subsequently Mickevich and Parenti (1980) leveled serious charges against Strauch's characters, method of phylogenetic inference, and results. To account for these charges, Strauch's characters were re-examined and recoded, and parsimony analyses were performed on the revised matrix. A parsimony analysis on 74 taxa from the revised matrix yielded 855 shortest trees, each length = 286 and consistency index = 0.385. In each shortest tree there were two major lineages, a lineage of sandpiper-like birds …
