Mining Spatial co-location Patterns with Star High Influence [PDF]

open access: yesJisuanji kexue, 2022
The spatial co-location pattern is a group of spatial features whose instances are frequently collocated in the spatial neighborhood.Traditional spatial co-location pattern mining methods usually assume that the spatial instances are independent each ...

Spatial patterns and associations of tree species at different developmental stages in a montane secondary temperate forest of northeastern China [PDF]

open access: yesPeerJ, 2021
Background Secondary forests have become the major forest type worldwide. Research on spatial patterns and associations of tree species at different developmental stages may be informative in understanding the structure and dynamic processes of secondary

Stomatal distribution pattern for 90 species in Loess Plateau – Based on replicated spatial analysis

open access: yesEcological Indicators, 2023
Stomata are the valves controlling carbon and water exchange between plant leaves and the atmosphere. Stomatal position changes throughout the whole growth of leaves, and the position is gradually fixed until the leaves mature, whether stomatal spatial ...

Integrated Analyses of PALSAR and Landsat Imagery Reveal More Agroforests in a Typical Agricultural Production Region, North China Plain

open access: yesRemote Sensing, 2018
As the largest among terrestrial ecosystems, forests are vital to maintaining ecosystem services and regulating regional climate. The area and spatial distribution of trees in densely forested areas have been focused on in the past few decades, while ...

Pairwise interaction point processes for modelling bivariate spatial point patterns in the presence of interaction uncertainty [PDF]

open access: yes, 2015
Current ecological research seeks to understand the mechanisms that sustain biodiversity and allow a large number of species to coexist. Coexistence concerns inter-individual interactions. Consequently, there is an interest in identifying and quantifying

Algorithm for analyzing randomness in point patterns

open access: yesMethodsX
Various tests can be used to assess whether the spatial distribution pattern of a set of points is random, dispersed, or clustered. These tests typically compare the expected and observed distances among points, assuming no barriers.
