The distribution of silicon deposits in the rhizomes of two Andropogon species

, : The distribution of silicon deposits in the rhizomes of two Andropogon species. Canadian Journal of Botany 52(6): 148-156

2 perivascular deposition sites for Si were detected in rhizomes of field samples of Andropogon gerardii and A. scoparius by electron-probe microassay. Si was confined to several layers of cells immediately outside the stele and occurred as Si aggregates restricted to the inner tangential walls. These Si-accumulating cells were similar in position, shape and wall thickness and Si deposition to the root endodermal cells of the same spp.

The fitness consequences of dispersal decisions are difficult to quantify, especially for long-lived species with complex social systems. To calculate those consequences for male mountain gorillas, from the perspective of both subordinate and domi...
