Towards A Systems Approach To Understanding Plant Cell Walls, Chris R. Somerville, Stefan Bauer, Ginger Brininstool, Michelle Facette, Thorsten Hamann, Jennifer Milne, Erin Osborne, Alex Paradez, Staffan Persson, Ted K. Raab, Sonja Vorwerk, Heather Youngs

Ted K. Raab

One of the defining features of plants is a body plan based on the physical properties of cell walls. Structural analyses of the polysaccharide components, combined with highresolution imaging, have provided the basis for much of the current understanding of cell walls. The application of genetic methods has begun to provide new insights into how walls are made, how they are controlled, and how they function. However, progress in integrating biophysical, developmental, and genetic information into a useful model will require a system-based approach.

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Philip J. Nyhus

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife conflict …
