  • Escherichia coli

    Escherichia coli cells with fluorescently labeled chromosomal loci. 

  • Drosophila

    Drosophila are small flies, typically pale yellow to reddish brown to black, with red eyes. Many species, including the noted Hawaiian picture-wings, have distinct black patterns on the wings. The plumose (feathery) arista, bristling of the head and thorax, and wing venation are characters used to diagnose the family.

  • Malaria parasites

    Malaria parasites (and their kin) can be viewed as minimal eukaryotes, harboring a nucleus (yellow), a secretory pathway the Golgi (purple) and specialized ‘rhotpry’ organelle (black), and two endosymbiotic organelles, the mitochondrion (red) and apicoplast (green).

  • Larix siberica

    Siberian Larch, taken at our field site near Lake Khovsgol in north-central Mongolia.  We are analyzing tree-ring width and stable isotopes of the tree rings to reconstruct climate, and Larch responses to climate change, over the past century as the temperature in Mongolia has risen.  

  • Courtship in Drosophila

    Various courtship songs produced by Drosophila species

Biology is fundamental to our changing world. The 21st century challenge for our students, our scholars, and the greater society is to understand our place in this changing world and to create fundamental knowledge for informed policies, economies, and social structure.

Math Modeling as a Tool to Understand Mayfly Emergence in White Clay Creek and How it Might be Impacted by Climate Change

Allison Kolpas, West Chester University
- | David Rittenhouse Laboratory A2

We develop a three-stage stochastic individual-based model for the phenology of the parthenogenetic mayfly Neocloeon triangulifer (Ephemeroptera: Baetidae). Mayflies are poikilothermic and develop at a rate dependent…
