Remoción de Semillas en Hábitats Transformados: Pogonomyrmex barbatus (Hymenoptera: Formicidae) y Cinco Especies de Cactáceas del Centro de México [PDF]
Sociobiology, 2014 One of the main consequences of human activities in semiarid zones is the transformation of habitats. In this work we studied the effect of this transformation on seed removal of five cacti species by the harvester ant Pogonomyrmex barbatus in the ...

Plant Responses to Anomalous Heat and Drought Events in the Sonoran Desert. [PDF]
Glob Chang BiolWhat are the impacts of region‐wide heat and drought events on desert vegetation? This multi‐scale assessment shows that columnar cacti and succulent trees show acute plant stress across the Sonoran Desert. The expected increased frequency of heat and drought events will likely have landscape‐wide impacts that could fundamentally reshape populations of

In situ ambient vibration modal analysis of saguaro cacti (Carnegiea gigantea). [PDF]
Am J BotAbstract Premise The structural and dynamic properties of columnar cacti are key inputs for stability analyses; however, no previous studies have been able to resolve these properties from full‐scale tests in situ. Methods I present an approach using non‐destructive ambient vibration data to measure the resonance properties (modal frequencies and mode ...

The leaf-footed cactus bug is not a cactus specialist: Narnia femorata feeds, fights, and mates on thistle. [PDF]
Ecol EvolWe recently found a population of the leaf‐footed cactus bug, Narnia femorata (Hemiptera: Coreidae), a historical cactus specialist, living on thistle. When we compared this thistle population with a population feeding on cactus, the population living on thistle had longer mouthparts than the population found on cactus, although this difference only ...

Anticancer and Antioxidant Activities of Rhizospheric Soil Bacteria of <i>Lophocereus marginatus</i>. [PDF]
Int J MicrobiolIdentification of new sources of compounds with anticancer and antioxidant potential is essential for cancer treatment. Rhizospheric bacteria have emerged as a promising source of these agents. This study is aimed at investigating the anticancer and antioxidant properties of bacteria isolated from the rhizosphere of Lophocereus marginatus.

Living Away From Specialized Pollinators: The Pollination System of Cieba Pentandra in the Yucatan Peninsula. [PDF]
Ecol EvolThe pollination system of C. pentandra was addressed. This system was highly generalized. ABSTRACT Plant‐pollinator systems can exist along the gradient from extreme specialization to extreme generalization. Theoretical work predicts that high pollinator reliability may lead to specialized pollination systems, while pollinator unpredictability may ...

Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats. [PDF]
Am J BotAbstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

Biomechanics of the columnar cactus Pachycereus pringlei [PDF]
American Journal of Botany, 1999 We report the longitudinal variations in stiffness and bulk density of tissue samples drawn from along the length of two Pachycereus pringlei plants measuring 3.69 and 5.9 m in height to determine how different tissues contribute to the mechanical stability of these massive vertical organs.
