Effects of Spatial Heterogeneity in Rainfall and Vegetation Type on Soil Moisture and Evapotranspiration
Michael J. Puma, Michael A. Celia, Ignacio Rodriguez-Iturbe +3
Nonlinear plant-scale interactions controlling the soil-water balance are generally not valid at larger spatial scales due to spatial heterogeneity in rainfall and vegetation type.…
On the Connections Between Surficial Processes and Stratigraphy in River Deltas
Michael J. Puma, Rachata Muneepeerakul, Chris Paola +2
We explore connections between surficial deltaic processes (e.g. avulsion, deposition) and the stratigraphic record using a simple numerical model of delta-plain evolution, with th…
Structure and Controls of the Global Virtual Water Trade Network
S. Suweis, M. Konar, C. Dalin +3
Recurrent or ephemeral water shortages are a crucial global challenge, in particular because of their impacts on food production. The global character of this challenge is reflecte…
On Species Persistence-Time Distributions
S. Suweis, E. Bertuzzo, L. Mari +3
We present new theoretical and empirical results on the probability distributions of species persistence times in natural ecosystems. Persistence times, defined as the timespans oc…
Spatial effects on species persistence and implications for biodiversity
Enrico Bertuzzo, Samir Suweis, Lorenzo Mari +3
Natural ecosystems are characterized by striking diversity of form and functions and yet exhibit deep symmetries emerging across scales of space, time and organizational complexity…
Models of Fractal River Basins
Marek Cieplak, Achille Giacometti, Amos Maritan +3
Two distinct models for self-similar and self-affine river basins are numerically investigated. They yield fractal aggregation patterns following non-trivial power laws in experime…
