number of fields now have less than 40 cm of soil (Shih et al., 1998). Second, for every cm of rainfall, the free Sugarcane (Saccharum spp.) is the primary crop on the Histosols water in the soil profile of EAA Histosols can be exof the Everglades Agricultural Area (EAA), where periodic floods pected to rise about 10 cm (Glaz et al., 2002). Finally, and undesirably high water tables are increas...

Heinz Ellenberg's historically important work on changes in the abundances of a community of grass species growing along experimental gradients of water table depth has played an important role in helping to identify the hydrological niches of plant species in wet meadows. We present a previously unpublished complete version of Ellenberg's dataset from the 1950s together with the results of a s...

Groundwater levels across parts of western Kansas have been declining at unsustainable rates due to pumping for agricultural irrigation despite water-saving efforts. Accelerating this decline is the complex landscape, consisting both categorical (e.g., management boundaries) and numerical crop prices) factors that drive decisions, making integrated water budget a challenge. Furthermore, these f...

Offshore platforms are known to act as artificial reefs, though there is on-going debate on whether this effect is beneficial or harmful for the life in the surrounding marine environment. Knowing what species exist on and around the offshore platforms and what environmental variables influence this species assemblage is crucial for a better understanding of the impact of offshore platforms on ...

This paper presents the multi-criteria calibration of a regional distributed subsurface water flow model for a 1400 km irrigated agricultural area in the western San Joaquin Valley of California. Two global optimization algorithms were used to identify model parameters using data on spatially distributed local water table depth measurements, district-average groundwater pumping and district-ave...

Longleaf pine savannas are one of the most threatened ecosystems in the world, yet are understudied. Ants are a functionally important and diverse group of insects in these ecosystems. It is largely unknown how local patterns of species diversity and composition are determined through the interaction of this dominant animal group with abiotic features of longleaf pine ecosystems. Here we descri...
