Design-based estimation of mark variograms in forest ecosystem surveys
Spatial Statistics, 2019Abstract Mark variograms are widely adopted in forest ecosystem studies for analyzing spatial interaction among trees. Inference on mark variograms can be performed under a model-dependent perspective (ergodic variograms) or under a deterministic perspective (non-ergodic variograms).

What mark variograms tell about spatial plant interactions
Ecological Modelling, 2013Many if not all data collected in ecology have both a spatial as well as a temporal dimension. This suggests the use of summary characteristics from spatial statistics to gain more refined insight into plant interactions. Spatial tree data can for example be considered as point patterns (formed by tree locations) with attached marks (e.g.

Mark variograms for spatio-temporal point processes
Spatial Statistics, 2017Abstract A spatio-temporal point process can be transformed into two marked point processes by taking the times or locations as marks. For these marked point processes mark variograms can be defined, opening a new way for the statistical analysis of spatio-temporal point processes.

On Variograms in Point Process Statistics, II: Models of Markings and Ecological Interpretation
Biometrical Journal, 2000[For part I see ibid. 38, No. 8, 895-905 (1996; Zbl 0878.62067).] This paper presents new models for marked point processes for describing forestry data. In these models two factors play a role: Long-range variability is modeled by a random field, which may describe environmental variability, while short-range variability is caused by the interaction ...

The quantification of big pools of diverse molecules provides important insights on brain function, but is often restricted to a limited number of observations, which impairs integration with other modalities. To resolve this issue, a method allowing for

Mark-mark scatterplots improve pattern analysis in spatial plant ecology
Ecological Informatics, 2019Point process statistics provides valuable tools for many ecological studies, where ‘points’ are commonly determined to represent the locations of plants or animals and ‘marks’ are additional items such as species or size.

This landmark paper by Burgess & Webster (1980a) signalled a new era in the spatial mapping 2 of the soil. The emergence of pedometrics as a distinct subdiscipline of soil science was a gradual 3 process, and had its roots in earlier studies than this ...
