FEMINIST the work of Peggy McIntosh, is used THEORY, PARTICULARLY to examine the development of multicultural literature for children and youth in the middle years of the twentieth century. The work of four white women writers-Florence Crannell Means, Ann Nolan Clark, Marguerite de Angeli, and Lois Lenski-is used as an example of the fiction created by outsiders to introduce often invisible cul...

Richard Lenski is the John Hannah Distinguished Professor of Microbial Ecology at Michigan State University. He studies the ecology, genetics and evolution of bacteria in an experimental setting that enables him to observe the dynamical processes and outcomes across many generations. One of his experiments with Escherichia coli has passed 30,000 generations and is still on-going. A few years ag...

All rights reserved. 0169-5347/98/$19.00 PII: S0169-5347(98)01372-X adaptation occurs even within strongly interacting, complex communities. These results demonstrate that multiple species interactions do not necessitate the diffusion of coevolutionary relationships. Emphasizing the value of this community perspective, Allen ...

The Lenski experiment investigates the long-term evolution of bacterial populations. In this paper we present an individual-based probabilistic model that captures essential features of the experimental design, and whose mechanism does not include epistasis in the continuous-time (intraday) part of the model, but leads to an epistatic effect in the discrete-time (interday) part. We prove that u...

Van Hofwegen et al. demonstrated that Escherichia coli rapidly evolves the ability to use citrate when long selective periods are provided (D. J. Van Hofwegen, C. J. Hovde, and S. A. Minnich, J Bacteriol 198:1022-1034, 2016, http://dx.doi.org/10.1128/JB.00831-15). This contrasts with the extreme delay (15 years of daily transfers) seen in the long-term evolution experiments of Lenski and cowork...

Bacteria live in complex multispecies communities. Intimately interacting bacterial cells are ubiquitous on biological and mineral surfaces in all habitats. Molecular and cellular biologists have unraveled some key mechanisms that modulate bacterial interactions, but the ecology and evolution of these associations remain poorly understood. One debate has focused on the relative importance of co...
