Cramer-von Mises test for the difference between the spatial distributions of two populations
This package offers an R interface to speed-up and facilitate employing the Cramer-von Mises test proposed by Stephen Syrjala to test for the difference between the spatial distributions of two populations sampled at the ...
Correlation analysis in the presence of spatial autocorrelation
This package aims to offer an R interface for the functions developed by Pierre Legendre to perform t-tests for correlation coefficients taking into account the spatial autocorrelation of the data. This package is actually ...

Generalized distance based Linear Discriminant Analysis
This package implements the generalized distance-based linear discriminant analysis method and one cross-validation method described in Anderson and Robinson (2003). It allows performing a discriminant analysis based on ...
Assumptions about survival estimates and dispersal processes can have severe impacts on population viability assessments
Population viability analysis (PVA) is a central tool for conservation decision-making. To ensure the reliability of PVA projections, it is important to identify factors that can introduce biases. This study addresses two ...
Metabarcoding the eukaryotic community of a threatened, iconic Mediterranean habitat: Posidonia oceanica seagrass meadows
Against the accelerating pace of worldwide species extinction, reliable biodiversity assessments are critical, both as baselines and to track potential declines. DNA metabarcoding techniques allow for fast and comprehensive ...

Green tea extracts containing Epigallocatechin-3-Gallate modulate facial development in Down syndrome
risomy of human chromosome 21 (Down syndrome, DS) alters development of multiple organ systems, including the face and underlying skeleton. Besides causing stigmata, these facial dysmorphologies can impair vital functions ...
Chironomus alchichica sp. n. (Diptera: Chironomidae) from lake alchichica, Mexico
Morphological analysis of all developmental stages (except female), mitochondrial DNA sequences from cytochrome c oxidase subunit I (cox1) and cytological analysis of the polytene chromosomes were used to describe a new ...
