Shaping species with ephemeral boundaries: the distribution and genetic structure of desert tortoise (Gopherus morafkai) in the Sonoran Desert region

Journal of Biogeography, Volume 43, Issue 3, Page 484-497, March 2016., 2016
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

A Phytogeographical Classification of the North American Pacific Coast Based on Climate, Vegetation and a Floristic Analysis of Vascular Plants

Journal of Botany, Volume 2009, Issue 1, 2009., 2009
This study was designed to explore floristic variation along the Pacific coast from Cook Inlet, Alaska, to the southern tip of Baja California, Mexico. Data corresponding to 965 phytosociological relevés (including 686 vascular plants) obtained by sampling 279 coastal sites were examined.

Spatial Variation in the Community of Insects Associated With the Flowers ofPachycereus weberi(Caryophyllales: Cactaceae)

Environmental Entomology, 2014
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,

Survival of Lymphoma-Bearing Mice by Pachycereus marginatus Cactus Extracts and Elucidation of Bioactive Compounds [PDF]

Natural Product Communications, 2019
Cancer is one of the leading causes of death worldwide and commonly becomes resistant to chemotherapy, therefore, it is important to search for and evaluate novel sources of nontoxic antitumor agents. The cactus Pachycereus marginatus is native to Mexico and is traditionally recommended to treat gastrointestinal infections. Tumor-bearing mice survival,
