[R-sig-eco] adehabitat and Lat Long data

Hi I have ARGOS satellite tag data from some some very long distance traveling sharks. These critters cover large chunks of the Atlantic; coordinates are in decimal degrees. It would love to apply the residenceTime function in the adehabitat package to try and segment the paths into broad

Re: [R-sig-eco] adehabitat and Lat Long data

Hello Mike, One approach may be to convert your coordinates to a custom continuous equidistant conic projection with a central meridian near the center of your coordinates. This should help minimize errors in distances calculated across a large area. Hope that is useful. Cheers, Jeff

[R-sig-eco] Multivariate ANOVA based on dissimilarities

Dear all, I’m using the function “adonis” (multivariate ANOVA based on dissimilarities) to study beta diversity of moths between altitudinal levels and seasons. My analysis is based on the example included in the vegan tutorial “Multivariate Analysis of Ecological Communities in R: vegan

Re: [R-sig-eco] Multivariate ANOVA based on dissimilarities

Mauricio, Nothing reproducible here (we don't have your data sets), not even the output. In your email you only write about adonis() and the p-values you got from adonis. On the other hand, your TukeyHSD() is based on betadisper(), and you never seem to check the betadisper() p-values. These
