TLDR
A general overview of the biological knowledge of the floristic province of the Tehuacan-Cuicatlan Valley in central-southern Mexico is presented in this paper.Abstract:
A general overview of the biological knowledge of the floristic province of the Tehuacan-Cuicatlan Valley in central-southern Mexico is presented. Floristic and faunistic richness and endemism, as well as uses of the flora are analyzed and discussed for this area, recently declared a biosphere reserve. The analysis shows that, in approximately 10 000 km2 the Tehuacan-Cuicatlan Valley contains between 10 and 11.4% of the Mexican flora. In addition, the valley possesses 365 endemic species that represent 13.9% of its flora. With respect to the fauna diversity, the available information is less comprehensive than for plants. Nevertheless, the study shows that the 11 species of amphibians, 48 species of reptiles, and 91 species of birds recorded for the valley surpasses the diversity found in other dry-lands of the world. In relationship to the mammals of the region, the available data are poor for most of the groups except for bats, for which 24 species have been reported. Regarding the use of the flora, the analysis revealed that 815 species are utilized by the people in the valley. A discussion related to future research activities is also included.read more

In situ Management and Domestication of Plants in Mesoamerica
TL;DR: 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.

TL;DR: The information allows visualizing co-occurrence of incipient and advanced forms of management at different intensity levels within and among species, which helps to postulate testable hypotheses on factors influencing plant management and domestication in an important area for studying the origins of agriculture.

TL;DR: This study systematizes ethnobotanical information about the interactions between people and plants, ethnofloristic richness, the relative importance of useful species richness in relation to general species richness, and plant management in the Tehuacán–Cuicatlán Valley of central Mexico to develop regional strategies of sustainable management of plant resources.

Centres of plant diversity : a guide and strategy for their conservation
TL;DR: This three-volume work covering nearly 250 major sites for conservation of plant diversity worldwide is concern about rapid global loss and degradation of natural ecosystems and it is hoped that areas of prime botanical importance will be ensured by an adequate commitment of resources.

Shade as a cause of the association between the cactus Neobuxbaumia tetetzo and the nurse plant Mimosa luisana in the Tehuacan Valley, Mexico.
TL;DR: The results suggest that the nurse-plant effect between Neobuxbaumia tetetzo and Mimosa luisana is chiefly the result of differential survival in shaded microsites with less direct solar radiation, and consequently with lower daytime temperatures and lower evaporative demand.

TL;DR: Contrary to findings for multiple pollinators of columnar cacti in extratropical deserts in North America, the relationships between N. tetetzo and nectar-feeding bats was strong and tightly coupled in Mexico.
