Mandujano M. C., Verhulst J. A. M., Carrillo-Angeles I. G., Golubov J., Population Dynamics of Ariocarpus scaphirostris Bödeker (Cactaceae): Evaluating the Status of a Threatened Species, International Journal of Plant Sciences, 2007, 168(7):1035-1044, doi: 10.1086/519008
Mapping 736 Ariocarpus scaphirostrus in one Rayones population and one annual observation interval provided a demographic analysis. The authors compared a matrix based on observations with one incorporating mortality borrowed from other cactus studies. The analysis emphasises plant survival in population dynamics. It also covers spatial clustering, size-class distribution and germination in light and darkness.
