Plant Ecology, 2006
Understanding the mechanisms that determine the distribution and abundance of plants is a major problem in ecology. However, very few studies have explored the factors controlling the abundance of columnar cacti throughout their range of distribution.

Flora, 2017
Abstract Studies on breeding systems and flower morphology are valuable to infer how environmental factors impose evolutionary change in plants. This study focused on the characterization of floral morphs and reproductive systems in Pachycereus pringlei and how this iconic columnar cactus might be a useful genus to understand the evolution of these

Journal of Arid Environments, 2008
Abstract The abundance of microorganisms in desert soil environments is closely related to the accumulation of resources around individual plants, called “islands of fertility”. This research was undertaken (1) to study the formation of islands of fertility in soils under Prosopis laevigata and Pachycereus hollianus in a preserved terrace and a ...

Abstract Few studies have determined the importance of orientation on flower reproductive success. Flower orientation may affect reproduction of Cactaceae; the interception of photosynthetic active radiation (PAR) differs along the different sides of cacti stems, and translocation of resources between cacti ribs does not appear to occur.

Columnar cacti are an essential resource in arid and semi-arid forests. Although they do not provide direct economic benefits, they are vital for maintaining the ecological balance of flora and fauna in desert ecosystems. Over the past 20 years, necrotic disease has been observed in the southern part of the peninsula, leading to a decline in wild ...
