A maximum-entropy description of animal movement
Chris H. Fleming, Yigit Subasi, Justin M. Calabrese
We introduce a class of maximum-entropy states that naturally includes within it all of the major continuous-time stochastic processes that have been applied to animal movement, in…
Minimal mechanisms for vegetation patterns in semiarid regions
Ricardo Martinez-Garcia, Justin M. Calabrese, E. Hernandez-Garcia +1
The minimal ecological requirements for formation of regular vegetation patterns in semiarid systems have been recently questioned. Against the general belief that a combination of…
Optimal search in interacting populations:Gaussian jumps vs Levy flights
Ricardo Martinez-Garcia, Justin M. Calabrese, Cristobal Lopez
We investigated the relationships between search efficiency, movement strategy, and non-local communication in the biological context of animal foraging. We considered situations w…
Exploring the tug of war between positive and negative interactions among savanna trees: Competition, dispersal, and protection from fire
Flora S. Bacelar, Justin M. Calabrese, Emílio Hernández-García
Savannas are characterized by a discontinuous tree layer superimposed on a continuous layer of grass. Identifying the mechanisms that facilitate this tree-grass coexistence has rem…
Optimizing the search for resources by sharing information: Mongolian gazelles as a case study
Ricardo Martínez-García, Justin M. Calabrese, Thomas Mueller +2
We investigate the relationship between communication and search efficiency in a biological context by proposing a model of Brownian searchers with long-range pairwise interaction.…
Spatial patterns in mesic savannas: the local facilitation limit and the role of demographic stochasticity
Ricardo Martinez-Garcia, Justin M. Calabrese, Cristobal Lopez
We propose a model equation for the dynamics of tree density in mesic savannas. It considers long-range competition among trees and the effect of fire acting as a local facilitatio…
