Across the process of domestication, human selection produces changes in target attributes as well as changes that are not necessarily desired by humans due to pleiotropic or linked genes. In this paper we addressed, correlated changes between genetic diversity, damage level, defense mechanisms (resistance and tolerance), and fitness due to the dom...

Stenocereus pruinosus and S. stellatus are columnar cacti from central Mexico, distributed in the Valle de Tehuacán and the Mixteca Baja regions. Both species have populations subject to three different forms of human management: wild, in situ and cultivated, growing in sympatry. The objectives of the present study were to compare variation in dama...

Antecedentes: La selección humana favorece rasgos de interés, pero también implica cambios en otros correlacionados. En especies con domesticación incipiente, la variación en la intensidad de selección genera una diferenciación entre sus poblaciones que permite analizar estos cambios. Pregunta: ¿Cómo son los cambios entre rasgos seleccionados y co...

Background Oaxaca is one of the most diverse states in Mexico from biological and cultural points of view. Different ethnic groups living there maintain deep and ancestral traditional knowledge of medicinal plants as well as traditional practices and beliefs about diseases/illnesses and cures. Previous ethnobotanical research in this state has help...

Resumen La intensidad de manejo en plantas está influida por factores socioecológicos, destacando el valor económico y la disponibilidad espacial de los recursos. Agave karwinskii es un recurso cultural, económica y ecológicamente relevante, con alta diversidad morfológica, la cual se refleja en la compleja nomenclatura tradicional. Algunos etnotax...

Background: Understanding changes in local community composition along environmental gradients is essential for studying the long-term metacommunity dynamics. The metacommunity structure depends on the distribution of species along environmental gradients in terms of their coherence (continuity in their distribution range), species turnover and gro...

Background: Field observations of damage in columnar cacti of central Mexico, and previous evidence in scientific literature, indicated the absence of systematic information about kinds of damage, vectors, and pathogens, in this botanical family. Questions: How is the knowledge of damage and defense mechanisms in cacti? Is there a pattern in causa...

Columnar cacti are distributed naturally in arid and semi-arid zones of America. Almost 50% are found in Mexico, were 45 species have been used for 8,500 years and currently are commercialized in regional or international markets. Rot damage in monopodic stems or branches was observed recently in columnar cacti of Central Mexico. Previous reports s...

The first report of transgenic maize in Mexico was published in 2001 for Oaxaca, Mexico. Subsequent studies were controversial, because most of the maize samples analyzed from different years and localities, were negative. The purpose of this paper is to publish records of the presence of transgenic maize in Priority Terrestrial Regions in Oaxaca,...

The ethnobotanical importance of the family Piperaceae is recognized mainly for its medicinal properties. A total of 106 species of two genera of this family (Piper and Peperomia) have been collected in Oaxaca, but only 18 are recorded in scientific publications as medicinal, edible, veterinary, or ritual plants. The objectives of this study are to...

Diversity and trophic structure of grain insect communities were examined in Olotillo, Nal‐Tel and Comiteco maize landraces cultivated within a milpa agroecosystem by Zapotec ethnic groups in Mexico. Higher insect diversity was expected in Olotillo, whose cultivation comprises a wide variety of agroecosystems, and low insect abundance in Nal‐Tel wi...

Historic demography changes of plant species adapted to New World arid environments could be consistent with either the Glacial Refugium Hypothesis (GRH), which posits that populations contracted to refuges during the cold-dry glacial and expanded in warm-humid interglacial periods, or with the Interglacial Refugium Hypothesis (IRH), which suggests...

Opuntia megarrhiza is an endemic species of Mexico, distributed in San Luis Potosi state. Medicinal use has been reported to prepare splints, mainly using the root. However, there are no studies on ecological aspects, to assess whether the current level of extraction by the people means some risk to the local populations. The objectives were: 1) to...

The endemic Mexican cactus, Mammillaria pectinifera, shows low dispersal capabilities and isolated populations within the highly dissected landscape of Tehuacán Valley. These characteristics can restrict gene flow and act upon the genetic divergence and speciation in arid plants. We conducted a phylogeographic study to determine if the origin, curr...

There is a growing interest in identifying plant speciation processes of Mexican arid biomes that originated its high flora richness, including cacti. Population genetics and phylogeography analysis allow to infer ecological and historical processes related to origin and distribution of diversity and speciation at infra specific level. We provide a...

Anoda cristata is a common weed used for food and medicine in central Mexico where it grows among field crops during the rainy seasons. People prefer robust, tender plants from the agricultural fields because these “develop better.” Hence, the plants are tolerated within the conventional agricultural activities and benefit indirectly from the impro...
