Dispersal and spatial heterogeneity: single species
Journal of Mathematical Biology, 2015A recent result for a reaction-diffusion equation is that a population diffusing at any rate in an environment in which resources vary spatially will reach a higher total equilibrium biomass than the population in an environment in which the same total resources are distributed homogeneously. This has so far been proven by Lou for the case in which the

Heterogeneity and Spatial Hierarchies
1991To apply the traditional scientific method, ecologists ordinarily focus on the mean or central tendency of a data set. For example, a typical hypothesis test would involve demonstrating that the mean is significantly different from a control measurement.

Spatial Preference Heterogeneity: A Choice Experiment
Land Economics, 2010The main objective is to assess preference heterogeneity related to the spatial distribution of water quality improvements throughout a river basin. In a choice experiment, the river basin's hydrogeographical units and the levels of water quality improvement are included as attributes in the experimental design.

Spatially Heterogeneous Dynamics in Supercooled Liquids
Annual Review of Physical Chemistry, 2000Although it has long been recognized that dynamics in supercooled liquids might be spatially heterogeneous, only in the past few years has clear evidence emerged to support this view. As a liquid is cooled far below its melting point, dynamics in some regions of the sample can be orders of magnitude faster than dynamics in other regions only a few ...

Spatial Heterogeneity in Production Functions Models
2015Controlling for unobserved heterogeneity is a fundamental challenge in empirical research, as failing to do so can introduce omitted variables biases and preclude causal inference. In this paper we develop an innovative method – the Iterative Geographically Weighted Regression (IGWR) method – to identify clusters of farms that follow a similar local ...
