Freshwater fish species richness on 132 West statistically significant, but add only a little to the variance already explained by ecological factors. Our analyses further European and North American rivers is analysed using indicate that rivers (which flow directly into the ocean) eleven variables related to contemporary ecology (nine) and support fewer species of fish than do similarly sized ...

In this paper, we study the performance of static solutions in two-stage adjustable robust packing linear optimization problem with uncertain constraint coefficients. Such problems arise in many important applications such as revenue management and resource allocation problems where demand requests have uncertain resource requirements. The goal is to find a two-stage solution that maximizes the...
