Spatial variability of soil properties and soil erodibility in the Alqueva reservoir watershed [PDF]
, 2015 The aim of this work is to investigate how the spatial variability of soil properties and soil erodibility (K factor) were affected by the changes in land use allowed by irrigation with water from a reservoir in a semiarid area.

Spatial scale effects in environmental risk-factor modelling for diseases
Geospatial Health, 2013 Studies attempting to identify environmental risk factors for diseases can be seen to extract candidate variables from remotely sensed datasets, using a single buffer-zone surrounding locations from where disease status are recorded. A retrospective case-

Metacommunity composition of web-spiders in a fragmented neotropical forest: relative importance of environmental and spatial effects. [PDF]
PLoS ONE, 2012 The distribution of beta diversity is shaped by factors linked to environmental and spatial control. The relative importance of both processes in structuring spider metacommunities has not yet been investigated in the Atlantic Forest.

Spatial variability and directional shifts in postural control in Parkinson’s disease
Clinical Parkinsonism & Related DisordersIndividuals with Parkinson's disease exhibit tremors, rigidity, and bradykinesia, disrupting normal movement variability and resulting in postural instability. This comprehensive study aimed to investigate the link between the temporal structure of postural sway variability and Parkinsonism by analyzing multiple datasets from young and older adults ...
