Opuntia in Habitat Biology is Important
Reproduction, DNA biology, and ecology are powerful drivers of
Opuntia biology. The genetics, biology, and speciation of Opuntia are poorly understood.
But, there are relevant publications, and our goal with this page is to provide access to some of the literature that does exist. This collection illuminates some areas of
Opuntia biology, but also raises other questions. For instance, why is polyploidy common in the genus? What factors control rampant hybridization.
We also provide a number of articles on general principles in plant biology as they relate to these topics.
Opuntiads are an amazing group of plants and we hope these articles help you appreciate them even more. The Publications A cyclical relationship between Larrea tridentata and Cylindropuntia leptocaulis A diffusion model for dispersal of Opuntia imbricata A flora of southern Arizona–Cactaceae A genomic view of introgression and hybrid speciation Arbuscular mycorrhizal fungal status of Opuntia humifusa A micromethod for recovery of DNA from Opuntia ficus-indica Breaking seed dormancy in Opuntia rastrera Cacti–biology and uses
