Modeling Influence of Soil Properties in Different Gradients of Soil Moisture: The Case of the Valencia Anchor Station Validation Site, Spain [PDF]

Remote Sensing, 2021
The prediction of spatial and temporal variation of soil water content brings numerous benefits in the studies of soil. However, it requires a considerable number of covariates to be included in the study, complicating the analysis.

Prediction and Surveillance Sampling Assessment in Plant Nurseries and Fields [PDF]

Applied Sciences, 2022
In this paper, we propose a structured additive regression (STAR) model for modeling the occurrence of a disease in fields or nurseries. The methodological approach involves a Gaussian field (GF) affected by a spatial process represented by an ...

Bayesian modelling for spatially misaligned health and air pollution data through the INLA-SPDE approach [PDF]

Spatial Statistics, 2019
Abstract In air pollution studies a key issue concerns the change of support: pollutant concentrations are continuous phenomena in space but their measurements are typically available at a finite number of point-referenced monitoring stations or result from numerical models.

Mapping habitat suitability of subtidal mussels Mytilus edulis in the Dutch western Wadden SeaZenodo [PDF]

Ecological Informatics
Understanding environmental predictor variables of species occurrence may contribute to conservation management. In this paper we test the use of a spatial binomial model, estimated with the combined INLA-SPDE method, to relate the probability of ...

Estimating scale‐dependent covariate responses using two‐dimensional diffusion derived from the stochastic partial differential equation method

Methods in Ecology and Evolution
Species distribution models (SDMs) are widely used to standardize spatially unbalanced data, project climate impacts and identify habitat for conservation.

Derivative-based spatial mediation with INLA-SPDE [PDF]

Spatial Statistics
In many applied fields, it may be of interest to evaluate mediational mechanisms occurring in spatial domains. The approaches proposed so far in the literature to address this issue deal with areal data and often consider linear models. In this paper, we

Spatio-temporal data fusion for the analysis of in situ and remote sensing data using the INLA-SPDE approach

Spatial Statistics
We propose a Bayesian hierarchical model to address the challenge of spatial misalignment in spatio-temporal data obtained from in situ and satellite sources. The model is fit using the INLA-SPDE approach, which provides efficient computation. Our methodology combines the different data sources in a "fusion"" model via the construction of projection ...

Identifying Ecological Corridors of the Bush Cricket <i>Saga pedo</i> in Fragmented Landscapes. [PDF]

Insects
The bush cricket Saga pedo, listed as Vulnerable globally by the IUCN and included in Annex IV of the EU Habitats Directive, is a parthenogenetic species highly sensitive to environmental changes, facing threats from forest expansion and agricultural ...

Increasing Prevalence of Plant-Fungal Symbiosis Across Two Centuries of Environmental Change. [PDF]

Glob Chang Biol
This research examines seeds sampled from historic herbarium specimens to look for changes in the presence of beneficial fungal symbionts in response to climate change drivers. These specimens from three grass host species are a window into the past, collected between 1824 and 2019, that, when combined with a flexible, spatially‐explicit statistical ...

On the Brink: Mapping the Last Strongholds of the Critically Endangered Flapper Skate (<i>Dipturus intermedius</i>). [PDF]

Ecol Evol
This study presents a high‐resolution spatial distribution model for the Critically Endangered flapper skate (Dipturus intermedius) across the NE Atlantic shelf, integrating environmental and fishing pressure data. Results highlight three core regions of presence off the coasts of Scotland and western Ireland, likely reflecting natural refugia and the ...
