Quantitative literacy is essential to biological literacy (and is one of the core concepts
in Vision and Change in Undergraduate Biology Education: A Call to Action;
AAAS 2009). Building quantitative literacy is a challenging endeavor for biology
instructors. Integrating mathematical skills into biological investigations can
help build quantitative literacy. In...
1. Chronic infections may have negative impacts on wildlife populations, yet their effects are difficult to detect in the absence of long-term population monitoring. Brucella abortus, the bacteria responsible for bovine brucellosis, causes chronic infections and abortions in wild and domestic ungulates, but its impact on population dynamics is not...

Smart growth strategies of infill and compact growth in existing suburban cities will most likely not be
sufficient to absorb a new US household growth in the future. To meet housing demands and preferences,
master-planned communities will continue to be built in outlying exurban areas. However, little is known
about...
This paper investigates the application of cellular automata (CA) models in bioeconomic studies involving varying biological growth and area distribution. A simple 2D continuous cellular automata (CCA) model is presented and incorporated in a fish harvest model based on standard assumptions of economic rational behaviour by individual decision makers. The...
The importance of large breeding individuals for maintaining the health of marine fish and invertebrate populations has long been recognized. Unfortunately, decades of human harvesting that preferentially remove larger individuals have led to drastic reductions in body sizes of many of these species. Such size-selective harvesting is particularly worrisome for...
Successful crop production depends initially on the availability of high-quality seed. By 2050 global climate change will have influenced crop yields, but will these changes affect seed quality? The present review examines the effects of elevated carbon dioxide (CO₂) and temperature during seed production on three seed quality components: seed...
One dimensional nonlinear difference equations have been used to model population growth. The standard biological models have the interesting characteristic that
they display global stability if they display local stability. Various researchers have sought
a simple explanation for this agreement of local and global stability. Here, we show that
enveloping...
