Analyses multivariées et mesures d'autocorrélation spatiale pour l'analyse des assemblages d'espèces

Spatial modeling: a comprehensive framework for principal coordinate analysis of neighbor matrices (PCNM)

Spatial structures of ecological communities may originate either from the dependence of community structure on environmental variables or/and from community-based processes. In order to assess the importance of these two sources, spatial …

Spatial modeling: a comprehensive framework for distance-based eigenvector maps (DBEM)

Broad-scale biodiversity pattern of the endemic tree flora of the Western Ghats (India) using canonical correlation analysis of herbarium records

A crucial step in understanding the origin and maintenance of biological diversity is the assessment of its distribution over space and time and across environmental gradients. At the regional scale, two important attributes of species can be …

Couplage de données issues de deux plans d'échantillonnage distincts d'un même espace

Multivariate analysis of incomplete mapped data

Classical multivariate analyses are based on matrix algebra and enable the analysis of a table containing measurements of a set of variables for a set of sites. Incomplete mapped data consist of measurements of a set of variables recorded for the …

Spatial variation in springtime food resources influences the winter body mass of roe deer fawn

It is well established that the dynamics of mammalian populations vary in time, in relation to density and weather, and often in interaction with phenotypic differences (sex, age and social status). Habitat quality has recently been identified as …

Matching data sets from two different spatial samples

Methods for coupling two data sets (species composition and environmental variables for example) are well known and often used in ecology. All these methods require that variables of the two data sets have been recorded at the same sample stations. …

Modelling bovine trypanosomosis spatial distribution by GIS in an agro-pastoral zone of Burkina Faso

Modelling of the spatial distribution of bovine trypanosomosis prevalence in Sideradougou district Burkina Faso was performed by using a combination of spatial and statistical analysis. Based on a comprehensive and geographically representative …
