Using spatial distance sampling models to optimize survey effort and address violations of the design assumption

open access: yesEcological Solutions and Evidence, 2021
Conventional distance sampling approaches rely on the design assumption (i.e. uniform distribution of individuals in relation to transects) to ensure unbiased inference to the population of interest.

Uncovering hidden spatial structure in species communities with spatially explicit joint species distribution models [PDF]

open access: yes, 2016
1. Modern species distribution models account for spatial autocorrelation in order to obtain unbiased statistical inference on the effects of covariates, to improve the model's predictive ability through spatial interpolation and to gain insight in the ...

Factors controlling the regeneration process in unevenly aged silver fir forests: inferences from the spatial pattern of trees [PDF]

open access: yesJournal of Forest Science, 2006
The main objective of this study was to prove the relationship between the spatial pattern of trees and distribution of advanced regeneration in structured Abies alba Mill. forests in the Western Carpathians (of southern Poland). In 13 sample plots (0.45-1.00 ha in size), the locations of all live trees above 15 cm in d1.3 and all stumps of canopy ...

Feature detection using spikes: the greedy approach [PDF]

open access: yes, 2005
A goal of low-level neural processes is to build an efficient code extracting the relevant information from the sensory input. It is believed that this is implemented in cortical areas by elementary inferential computations dynamically extracting the ...

Forward and backward inference in spatial cognition.

open access: yesPLoS Computational Biology, 2013
This paper shows that the various computations underlying spatial cognition can be implemented using statistical inference in a single probabilistic model.

Inferring Processes from Spatial Patterns: The Role of Directional and Non–Directional Forces in Shaping Fish Larvae Distribution in a Freshwater Lake System

open access: yesPLoS ONE, 2012
Larval dispersal is a crucial factor for fish recruitment. For fishes with relatively small-bodied larvae, drift has the potential to play a more important role than active habitat selection in determining larval dispersal; therefore, we expect small-bodied fish larvae to be poorly associated with habitat characteristics.

INLA or MCMC? A Tutorial and Comparative Evaluation for Spatial Prediction in log-Gaussian Cox Processes [PDF]

open access: yes, 2012
We investigate two options for performing Bayesian inference on spatial log-Gaussian Cox processes assuming a spatially continuous latent field: Markov chain Monte Carlo (MCMC) and the integrated nested Laplace approximation (INLA). We first describe the

Data integration for inference about spatial processes: A model-based approach to test and account for data inconsistency.

open access: yesPLoS ONE, 2017
Recently-developed methods that integrate multiple data sources arising from the same ecological processes have typically utilized structured data from well-defined sampling protocols (e.g., capture-recapture and telemetry).
