Bee species interact differently with flowers, playing different roles in pollination. For gynodioecious plant populations, which consist of two sexes (female-non-pollen-producing flowers and hermaphroditic flowers), bee–flower interactions also have ecological implications, including the maintenance of females. We evaluated bee performance on a gy...
The carnivorous habit has been interpreted as an outstanding adaptation that let some plants the acquisition of mineral nutrients in habitats characterized by a chronic scarcity of nutrients. Substantial evidence indicates how carnivorous plants benefit from its interaction with prey. However, fitness of carnivorous plants depends not only on the i...
El objetivo de este capítulo es exponer la necesidad de abordar las problemáticas ambientales (a través de un ejemplo en la Sierra de Huautla), bajo un enfoque transdisciplinar, con énfasis en dos aspectos: 1) El reconocimiento de las problemáticas ambientales como problemáticas complejas, 2) La importancia de adentrarse en el conocimiento de los m...
Dalbergia granadillo Pittier and D. stevensonii Standl. are two important native timber-yielding forest tree legume species,
the frst distributed along the Pacifc coast of Mexico and southwestern Mexico, and the other in southwestern Mexico.
Both are threatened by illegal trade, deforestation, and habitat fragmentation. To generate information to h...
Abstract. Threatened species frequently have a J-shaped population structure, which indicates a reduction in seed set and poor or nonexistent recruitment. Altered population structures may be due to disrupted demographic processes that result in low reproductive success or small population size. Peyote—Lophophora diffusa Croizat (Bravo)—is a rare,...
Floral traits and sexual systems in angiosperms are strategies that enhance out-crossing within hermaphrodite flowers and among individuals in a population. Sexual systems with unisexual flowers have also evolved among angiosperms, resulting in sex specialization. Furthermore, the interaction of floral traits and floral visitors determines successf...
The globose cactus Ariocarpus fissuratus, known as “living rock,” is renowned for the singular morphology of its extremely cryptic single stem/taproot, which results in a resemblance of their tubercles to rocky soil. Their beauty has placed Ariocarpus among the top rated illegally traded cactus. In the Cuatro Ciénegas Basin, important populations o...
Ariocarpus fissuratus is a subglobose cactus, endemic of the Chihuahuan Desert, from San Luis Potosí, Mexico to south of Texas, restricted to limestone soils. Its stem resembles the soil surface where it grows; therefore, it is commonly known as “living rock” or falso peyote. Under harsh conditions, its taproot shrinks, enhancing its survival by ma...
In this study, we carried out an inventory of butterfly diversity and an analysis of alpha and beta diversity considering the effects of phenology and degree of disturbance in tropical dry forest. The study included three localities: Cañadas de Ajuchitlán and El Limón, situated within the Sierra de Huautla Biosphere Reserve (REBIOSH) natural protec...
Objetivo: Dentro de la crisis global de biodiversidad, un tema de gran preocupación ha sido la pérdida de las abejas polinizadoras. No obstante, la información está notablemente sesgada hacia la abeja mielera (Apis mellifera) y los abejorros (género Bombus). El objetivo de este trabajo es resaltar la importancia de las abejas silvestres como polini...
p>We analyzed the traditional knowledge and management of local wild fauna and flora among the inhabitants of the peasant community of Chimalacatlán, together with their perception of local environments, to identify potential species for the future development of a sustainable resource management program. Initial contact with the community was esta...
Plant fitness is reduced by pollen limitation when the amount and quality of pollen deposited on stigmas is restricted. Pollen limitation has direct implications in mating system and floral evolution, and negatively affects population dynamics. We assessed pollen limitation in the cactus Ariocarpus kotschoubeyanus from the western Chihuahuan Desert...
Premise of research. Plant sexuality evolves in response to genetic and ecological pressures that shape mating systems and floral traits. Comparing such systems and traits within phylogenies can show evolutionary trends in reproduction and floral morphology without the problems posed by the nonindependence of species. We compared sexual systems in...
Self-incompatibility (SI), the most effective mechanism to prevent selfing, may limit the number of compatible mates in populations. The seven species of Ariocarpus are endangered and predominantly outcrossers but fruit set may reach 1-20% after selfing. We aimed to determine whether SI is the underlying mechanism influencing mating in Ariocarpus s...
Background/Question/Methods
Sexual systems evolve by preventing inbreeding depression and responding to ecological factors that limit fitness, such as rarity. We compared sexual systems in the monophyletic genus Ariocarpus to determine whether biogeographic rarity and reproductive traits were related. Additionally, we compared floral morphology am...
Background/Question/Methods
Biological invasions constitute a major threat to global diversity because invasive species can compete with or displace native species. Clonality is a common feature among invasive plant species because promotes long-distance dispersal and local persistence. Kalanchoe delagoensis, a succulent plant native to Madagasca...
Describimos la distribución conocida y potencial de las especies del género Ariocarpus. Todas las
especies están en alguna categoría de riesgo de extinción, listadas en la Norma Oficial Mexicana,
en la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza (iucn) y en la
Convención sobre el Comercio Internacional de Especies Ame...
The genus Ariocarpus comprises seven endangered species endemic to the Chihuahuan Desert. We studied the reproductive ecology of Ariocarpus fissuratus at Cuatrociénegas region, Mexico, in order to explore if reproductive traits influence population viability. The size of perianth, pistils and stamens, floral behavior and controlled pollination trea...
Floral biology in the Cactaceae represents a new field of research, with only 2% of approximately 2,000 species having been
studied. Studies on breeding systems cover functional and morphological floral traits of sexual expression, while research
on mating (hybridization) systems includes experiments on pollination, morphological and functional flo...
Background/Question/Methods . It is acknowledge that inbreeding depression is a consequence of selfing, so mechanisms that avoid self-fertilization have evolved in angiosperms. However, selfing is a viable strategy to ensure progeny under harsh environmental conditions. Self-incompatibility (SI) is the most effective mechanism that precludes self-f...
El género Ariocarpus Scheidweiler es un taxón de plantas geófitas, endémicas del desierto Chihuahuense. Las poblaciones naturales de este grupo han sido blanco de colecta y de tráfico ilegales ya que son sumamente apreciadas por cactófilos y coleccionistas nacionales y extranjeros, de ahí que sean especies
consideradas por varias listas rojas. A pr...
