Spatial Variance in Ecology

Oikos, 1995
Spatial variance of observed measures such as density is no longer viewed as a statistical annoyance. It is now treated as a biologically important quantity that changes value depending on the scale of measurement. Processes that generate spatial variance are often inferred by matching scales of maximum biological spatial variance to dominant physical ...

Spatial autocorrelation of ecological phenomena

Trends in Ecology & Evolution, 1999
Ecological variables often fluctuate synchronously over wide geographical areas, a phenomenon known as spatial autocorrelation or spatial synchrony. Development of statistical approaches designed to test for spatial autocorrelation combined with the increasing accessibility of long-term, large-scale ecological datasets are now making it possible to ...

Spatial Ecologies

2012
Spatial Ecologies takes a new look at the “spatial turn” in French cultural and critical theory since 1968. Verena Andermatt Conley examines how Henri Lefebvre, Michel de Certeau, Jean Baudrillard, Marc Augé, Paul Virilio, Bruno Latour and Etienne Balibar reconsider the experience of space in the midst of considerable political and economic turmoil ...

Socio-spatial organization and spatial ecology

2017
Home ranges of males (1204 km2) and females (1510 km2) were similar. Female home range size was positively related to the dispersion of prey and generally, but not exclusively, they displayed home range fidelity. Overlap between female home ranges was extensive, although they rarely met up.

The spatial ecology of microbes

2023
Tesis (Doctoral of Philosophy degree in Biological Sciences : Ecology)--Pontificia Universidad Católica de Chile, 2021 ; Guided by cell biophysics experimentation and equipped with toolsets from theoretical ecology, the aim of my thesis is to explore the ways in which spatial structure influences the dynamics and distributions of microbial cells ...

SPATIAL MODELING IN ECOLOGY: THE FLEXIBILITY OF EIGENFUNCTION SPATIAL ANALYSES

Ecology, 2006
Recently, analytical approaches based on the eigenfunctions of spatial configuration matrices have been proposed in order to consider explicitly spatial predictors. The present study demonstrates the usefulness of eigenfunctions in spatial modeling applied to ecological problems and shows equivalencies of and differences between the two current ...

Spatial Scaling in Ecology

Functional Ecology, 1989
Acts in what Hutchinson (1965) has called the 'ecological theatre' are played out on various scales of space and time. To understand the drama, we must view it on the appropriate scale. Plant ecologists long ago recognized the importance of sampling scale in their descriptions of the dispersion or distribution of species (e.g.

Self-organization in spatial ecology

Current Biology
Biologists have long known that populations of organisms - microbes, plants, animals - can self-organize into emergent patterns. Yet, the fact that such patterns can arise with remarkable symmetry at the scale of entire ecosystems remains astonishing, even as aerial imagery has documented their existence across all continents.

SPATIAL POINT PROCESSES, WITH APPLICATIONS TO ECOLOGY

Biometrika, 1955
The term 'point processes ', referring to stochastic processes in which events occur at more or less irregular intervals and which are represented by points on the time-axis, is of comparatively recent origin, although the existence of such processes has in fact been well known for a long time.
