Biological diversity in the Tehuacán-Cuicatlán Valley, Mexico
A general overview of the biological knowledge of the floristic province of the Tehuacán-Cuicatlán Valley in central-southern Mexico is presented. Floristic and faunistic richness and endemism, as
Knowledge and Use Value of Plant Species in a Rarámuri Community: A Gender Perspective for Conservation
We used a quantitative ethnobotanical approach to analyze factors influencing the use value of plant species among men and women of the Rarámuri people in Cuiteco, Chihuahua, Mexico. We constructed a
In situ Management and Domestication of Plants in Mesoamerica
Artificial selection operating on in situ managed populations of the species analysed is causing incipient domestication, which could be acting on any of the 600-700 plant species documented to be under in situ management in Mesoamerica.
Ecological and socio-cultural factors influencing plant management in Náhuatl communities of the Tehuacán Valley, Mexico
It is expected that both natural and human pressures generate risk on plant resources availability, influencing human responses of management directed to decrease risk, and magnitude of risk would be a direct function of human pressures favored by cultural and economic value and ecological factors such as scarcity.
Morphological variation and the process of domestication of Stenocereus stellatus (Cactaceae) in Central Mexico.
Whether morphological divergence between manipulated and wild populations has resulted from domestication processes has been evaluated to find sweet fruits with pulp colors other than red were more frequent in cultivated populations than fruits from wild individuals.
Pollination biology of two winter-blooming giant columnar cacti in the Tehuacán Valley, central Mexico
It is found that nectar-feeding bats have a small resident population in the Tehuacan Valley and these cacti species grow along possible routes of bat altitudinal migration, and a long, and possibly variable flowering season may be also related to low pollen vector density.
Plant resources of the Tehuacán-Cuicatlán valley, Mexico
Local knowledge on use and management of plants is a valuable source of information for designing conservation and social development strategies for the biosphere reserve Tehuacán-Cuicatlan, Mexico.
Genetic Structure of Wild and Domesticated Populations of Capsicum annuum (Solanaceae) from Northwestern Mexico Analyzed by RAPDs
The considerable genetic distances among cultivars as well as the high number of diagnostic bands per cultivar suggest that genetic changes associated with domestication could have resulted from artificial selection intervening in different directions, but the inclusion of more domesticated samples might clarify the nature of distinctions detected here.
Seed germination of wild and cultivated Stenocereus stellatus (Cactaceae) from the Tehuacán-Cuicatlán Valley, Central México
It is suggested that human selection has favoured seedling vigour and a greater germination capacity in cultivated variants of the columnar cactus Stenocereus stellatus.
