Research articles that will be published in the October 2008 issue of BioScience are as follows:

Fungal Community Ecology: A Hybrid Beast with a Molecular Master.
Kabir G. Peay, Peter G. Kennedy, and Thomas D. Bruns.

DNA-based techniques have in recent years allowed the systematic exploration of fungal diversity for the first time. Results show extremely high diversity and variability of fungi in natural environments, the explanation for which is unknown. High-throughput DNA sequencing has the potential to characterize this diversity in a class of organisms that is ecologically hugely significant worldwide.

Consequences of More Extreme Precipitation Regimes for Terrestrial Ecosystems.
Alan K. Knapp and colleagues.

The authors present a scheme for analyzing the effects on ecosystems of expected changes in patterns of precipitation. Moist ecosystems can be expected to suffer more water stress, while arid ecosystems are thought likely to have increased water availability. Wetlands are predicted to experience low-oxygen conditions less frequently.

Modeling the Developing Drosophila Brain: Rationale, Technique, and Application.
Volker Hartenstein, Albert Cardona, Wayne Pereanu, and Amelia Younossi-Hartenstein.

Modern digital modeling programs provide the opportunity to develop detailed three-dimensional maps of even such a complex structure as a brain. Modeling the developing brain of the fruit fly, the favorite experimental animal of geneticists, is providing new insights into how the process unfolds, and can reveal the effects of particular genes at various scales. Eventually, complete brain maps showing the interconnections of individual neurons should be achievable.

Comparing Ecosystem Goods and Services Provided by Restored and Native Lands.
Walter K. Dodds, Kymberly C. Wilson, Ryan L. Rehmeier, G. Layne Knight, Shelly Wiggam, Jeffrey A. F
