Abstract Aim We examine the role biogeographical features played in the evolution of Morafka's desert tortoise (Gopherus morafkai) and test the hypothesis that G. morafkai maintains genetically distinct lineages associated with different Sonoran Desert biomes. Increased knowledge of the past and present distribution of the Sonoran Desert region's biota

Pollen morphology of Pachycereus weberi (Cactaceae): an evaluation of variation in pollen size
Pollen morphology within a single plant species has been regarded as a relatively constant trait; it has, thus, been used as a taxonomic character. Numerous palynological studies have described the morphology of pollen from Cactaceae and from other families of plants.

Morpho-anatomy of seedlings in Pachycereeae species: until when are they seedlings?
Morpho-anatomy of species in Tribe Pachycereeae seedlings is described and compared with the aim to find differences between the initial growth and establishment stages and to determine the point in time of the change from seedling to young plant.

The positive relationship between productivity and species diversity is well-known. Insect communities associated with the flowers of Cactaceae species represent an interesting system to explore the productivity-diversity relationship because branches facing the equator receive more photosynthetically active radiation and have higher productivity. Thus,
