Species richness-environment relationships of European arthropods at two spatial grains: habitats and countries [PDF]

open access: yes, 2012
We study how species richness of arthropods relates to theories concerning net primary productivity, ambient energy, water-energy dynamics and spatial environmental heterogeneity.

Understanding patterns of HIV multi-drug resistance through models of temporal and spatial drug heterogeneity

open access: yeseLife, 2021
Triple-drug therapies have transformed HIV from a fatal condition to a chronic one. These therapies should prevent HIV drug resistance evolution, because one or more drugs suppress any partially resistant viruses.

Effects of Plateau Pika Disturbance on the Spatial Heterogeneity of Vegetation in Alpine Meadows

open access: yesFrontiers in Plant Science, 2021
Herbivory is one of the important factors that influence spatial heterogeneity of vegetation in grasslands. In this study, we focused on plateau pika (Ochotona curzoniae) to investigate the effects of the presence of small semi-fossorial herbivores and ...

Modeling Spatial Interaction in Stochastic Frontier Analysis

open access: yesFrontiers in Sustainable Food Systems, 2021
We compare farm level efficiency rankings derived from non-spatial and a variety of spatial model specifications that account for unobserved heterogeneity in both the production and the efficiency sides of the stochastic frontier model in an empirical ...

A simulation study on specifying a regression model for spatial data: choosing between heterogeneity and autocorrelation effects [PDF]

open access: yes, 2018
In this simulation study, regressions specified with autocorrelation effects are compared against those with relationship heterogeneity effects, and in doing so, provides guidance on their use. Regressions investigated are: (1) multiple linear regression,

FunSpace: A functional and spatial analytic approach to cell imaging data using entropy measures.

open access: yesPLoS Computational Biology, 2023
Spatial heterogeneity in the tumor microenvironment (TME) plays a critical role in gaining insights into tumor development and progression. Conventional metrics typically capture the spatial differential between TME cellular patterns by either exploring ...

Genome-scale investigation of olfactory system spatial heterogeneity. [PDF]

open access: yesPLoS ONE, 2017
The early olfactory system is organized in parallel, with numerous, specialized subsystems established by the modular and topographic projections of sensory inputs.

Landscape composition and configuration relatively affect invasive pest and its associator across multiple spatial scales

open access: yesFrontiers in Sustainable Food Systems, 2023
Landscape structures affect pests, depending on compositional heterogeneity (the number and proportions of different habitats), configurational heterogeneity (spatial arrangement of habitats), and spatial scales.

Scale effects on spatial heterogeneity of herbaceous vegetation in desert steppe depend on plant community type

open access: yesEcological Indicators, 2021
Spatial heterogeneity plays a crucial role in affecting the ecologial processes in natural ecosystems, yet how spatial heterogeneity of herbaceous vegetation in desert-grassland transitional zone varies with increased spatial scale are still poorly known.
