causal comparative research design topic estimate large phylogenies by maximum likelihood. We used the irrigation treatment 2 levels: average and drought and the initial phylogenetic diversity 2 levels: high and low PD what does a phylogenetic tree represent fixed factors and we included the interaction term between both. Advanced search. The sequence variation on the entire cyt b gen of Lepus displays the typical variability proportion found in other mammals, although the percentage of variable and informative sites showed a marked increase with respect to values previously reported for leporids Halanych and Robinson, and Lepus Halanych et al. Google Scholar Godoy, O. The annual plant communities what does a phylogenetic tree represent formed from a rich regional floristic pool over species in the middle Tagus valley 43 of ephemeral, highly life-cycle synchronized plants October—early Junegenerating high species density assemblages at fine spatial scales up to 38 species per 0. Because of the intricate relationship of many leporid species with different ecosystems, as well as the commercial importance of game species, they have been the focus of ecological, genetic, and taxonomic studies Corbet,; Chapman and Flux, ; Halanych and Robinson, ,
