Mixture models and comparative analysis of life history traits of teleost fishes Modele de melange et analyse comparative des traits demographiques des poissons
The comparative app roach in biology is used to investigate the attributes of actual species. Differences between them arc used to formulate adaptive hypotheses of life history, morphology, demography, etc. Difficulties arise from the phylogenetic heritage: species arc not independent and neglecting this fact can lead to inaccurate results. Fishing can have important effects but usually they arc mixed with ocher variations such as environmental ones. Single species studies cannot succeed completely in analysing the effect of fishing. To disentangle them from other fluctuations, we arc led to the use of a comparative approach. Thus, we need to account for phylogenetic links between populations. In this paper we propose a new family of models, which allows us to split life history traits into parts.
