“…Acanthocereus occidentalis Britton & Rose (1920: 125) has been mentioned for Durango at least since almost four decades (Martínez 1979) and is cited for the state in the Catalog of Mexican Cacti (Guzmán et al 2003 Britton & Rose (1909: 429). García Rubio et al (2015), in a study on the distribution range of Hylocereus in Mexico, record H. purpusii on the Pacific coast but discard its presence in Durango due to the lack of reference specimens in the herbaria consulted. Both taxa were collected in tropical deciduous forest in the municipalities of Pueblo Nuevo, San Dimas and Tamazula, thereby expanding the known distribution of both species.…”

Updated checklist and conservation status of Cactaceae in the state of Durango, Mexico

An updated and annotated checklist of Cactaceae in the Mexican state of Durango is provided, supported by a thorough examination of specialized literature and herbarium specimens, as well as field work. Additionally, geographical distribution, endemism and conservation status of the species were analyzed based on a compiled data matrix with 2326 georeferenced records. Cactaceae comprises 137 species and 29 genera in Durango, which represent a high proportion of the Mexican cactus flora: 46−58% at the generic level and 20−23% at the specific level. The estimated richness according to Chao-2 and Jackknife-1 is 143 and 151 species respectively, which means that the inventory we present here for the Cactaceae of Durango is complete in 91 to 96%. Since no herbarium specimens nor registers in reliable data bases were found to support their presence in the area, 46 taxa were excluded; even so, this inventory increases by 30% the cacti richness previously reported for Durango and provides new information on the distribution range of many species. The richest genera are Mammillaria, Opuntia, Coryphantha and Echinocereus. The highest concentration of species occurs in the arid and semiarid zone of eastern Durango, although there are also some spots with significant richness in the tropical region on the western slopes of the Sierra Madre Occidental. 75% of the species are endemic to Mexico, 41% are regional endemics and 5% are restricted to Durango. New records and relevant novelties are also discussed.Key words: cacti, Chihuahuan Desert, distribution, richness, Sierra Madre Occidental ResumenSe presenta una lista actualizada y comentada de las cactáceas de Durango respaldada en una revisión exhaustiva de literatura especializada, especímenes de herbario y trabajo de campo. Además, se analiza la distribución geográfica, endemismo y estatus de conservación de las especies con base en una matriz de datos con 2326 registros georreferidos. Cactaceae incluye 137 especies de 29 géneros en Durango, lo que representa una alta proporción de la flora cactológica mexicana: 46−58% de los géneros y 20−23% de las especies. La riqueza estimada según Chao-2 y Jackknife-1 es 143 y 151 especies, respectivamente, lo que significa que el inventario de Cactaceae de Durango que presentamos aquí está completo en 91 a 96%. Se excluyó un gran número de taxones (46), ya que no se encontraron especímenes de herbario, ni registros en bases de datos confiables que apoyen su presencia en el área de estudio; aun así, este inventario incrementa en 30% la riqueza de cactus registrada antes para Durango y provee información novedosa sobre los rangos de distribución de muchas especies. Los géneros más ricos son Mammillaria, Opuntia, Coryphantha y Echinocereus. La mayor concentración de especies ocurre en la región árida y semiárida del oriente de Durango, aunque también hay algunos puntos con riqueza considerable en la región tropical en la vertiente occidental de la Sierra Madre Occidental. 75% de las especies registradas son endémicas a México, 4...

“…Recognition of species in this group remains controversial. Here S. ocamponis is recognized including S. purpusii , although they often are separated by some authors (Bauer, 2003; García-Rubio et al ., 2015). S. costaricensis is poorly understood, similar to S. escuintlensis and S. guatemalensis (Bauer, 2003); here it is identified as the species with purplish peel and pulp distributed in Costa Rica.…”

Optimal areas and climate change effects on dragon fruit cultivation in Mesoamerica

et al. 2020

View full text Add to dashboard Cite

Climbing cacti with edible fruits have been proposed as new dryland fruit crops because their high water-use efficiency reduces water requirement. One lineage of climbers in the cactus family, the Hylocereus group of Selenicereus, includes several species that produce edible fruits and is currently cultivated around the world. Fruits are known as pitahayas, pitayas or dragon fruit. Here, by means of ecological niche-based modelling and analytical hierarchical modelling, the optimal areas for cultivating the three main species of this group in Mesoamerica – Selenicereus costaricensis, Selenicereus ocamponis and Selenicereus undatus – are identified. Data on distribution, physiological requirement and host preferences are taken into account to carry out ecological modelling for current and future scenarios of climate and determine its impact on cultivation. Two MIROC climatic future models, one optimistic (ssp216) and a pessimistic (ssp585) were selected and 554 records from Mexico and Central America were gathered. For all three species, temperature and precipitation seasonality, and solar radiation were the most significant variables in the niche modelling. In addition, for S. undatus the most important hosts, three species of mesquite legume trees were significant to forecast suitable areas for planting. Large areas on the Pacific side from Sinaloa to Costa Rica were predicted as favourable for cultivating the studied three species. Future scenarios of climate change predicted increase of suitable areas for two species and in particular for S. undatus the increment was the largest. Therefore, dragon fruits are corroborated as promising fruits in view of climate change.

“…laevigatus is separated from S . pruinosus by the biotic barrier of the Isthmus of Tehuantepec [ 22 ] ( Fig 3 ) which we identified as a genetic barrier, although not common for the Cactaceae; [ 24 , 25 , 68 , 69 ]. The core distribution of S .…”

Species delimitation in the Stenocereus griseus (Cactaceae) species complex reveals a new species, S. huastecorum

et al. 2018

View full text Add to dashboard Cite

The Stenocereus griseus species complex (SGSC) has long been considered taxonomically challenging because the number of taxa belonging to the complex and their geographical boundaries remain poorly understood. Bayesian clustering and genetic distance-based methods were used based on nine microsatellite loci in 377 individuals of three main putative species of the complex. The resulting genetic clusters were assessed for ecological niche divergence and areolar morphology, particularly spination patterns. We based our species boundaries on concordance between genetic, ecological, and morphological data, and were able to resolve four species, three of them corresponding to S. pruinosus from central Mexico, S. laevigatus from southern Mexico, and S. griseus from northern South America. A fourth species, previously considered to be S. griseus and commonly misidentified as S. pruinosus in northern Mexico showed significant genetic, ecological, and morphological differentiation suggesting that it should be considered a new species, S. huastecorum, which we describe here. We show that population genetic analyses, ecological niche modeling, and morphological studies are complementary approaches for delimiting species in taxonomically challenging plant groups such as the SGSC.
