“…The SMOR as delimited by Cervantes-Zamora et al (1990, Figure 1) has higher floristic richness than any other mountainous region of Mexico. Its 8,472 species identified in this work exceed the 6,981 species of the SMOR flora reported by Salinas-Rodríguez et al (2022), and exceeds preliminary estimates for other important mountain ranges (Villaseñor, unpublished data), including the Trans-Mexican Volcanic Belt (6,751 species), the Sierra Madre Occidental (6,628) and the Sierra Madre del Sur (5,874). A progressive decrease of the geographical ranges of the characteristic species is observed, with sites further away from the SMOR recording low species numbers, showing the typical decline in floristic similarity discussed in ecology (Nekola & White 1999).…”

“…Considering our results, it is evident that there continues to be a lack of academic consensus on the delimitation of the SMOR province in biogeographic, floristic (see Salinas-Rodríguez et al 2022), and physiographic terms. The evidence analyzed highlights the need to carry out similar analyses in neighboring provinces, including the Altiplano province to the west and the Gulf of Mexico Coast to the east.…”

“…Salinas-Rodríguez (2015) synthesized a first approximation of the flora of the SMOR, reporting 7,748 species, distributed in 1,852 genera and 203 families. Recently Salinas-Rodríguez et al (2022) updated the former data publishing a floristic checklist of the SMOR including 6,981 species. Additionally, botanical exploration has led to the publication of some 42 local floristic inventories carried out in the SMOR and neighboring regions that are sometimes considered part of the mountain range (Table 1).…”

Background: Different regionalizations have been proposed for the Sierra Madre Oriental (SMOR), but none of them have analyzed its full floristic diversity. Hypothesis: The geographical distribution of the vascular plant species of the SMOR allows the identification of floristic regions with unique species that identify them as biogeographic units. Studied species: Vascular plants. Study site: Sierra Madre Oriental physiographic province, Mexico. Methods: Plant species distribution was analyzed in 1 × 1° latitude and longitude grid cells. Characteristic species (those with half or more of their known geographical distribution in Mexico in the SMOR) were identified, and a classification method was applied to distinguish biogeographic regions. Results: 8,472 species were recorded in the Sierra Madre Oriental, 3,433 of them considered characteristics, of which 2,158 are endemic to Mexico and 585 are considered strictly endemic to the province. The portions of the SMOR in the states of Coahuila, Nuevo León, Tamaulipas, and San Luis Potosí have a higher species richness and this richness decreases towards the south of the province. Five floristic districts were identified within the SMOR. Conclusions: The phytogeographic analysis carried out and its comparison with other regionalizations shows there is still disagreement in the biogeographic delimitation of the Sierra Madre Oriental and to achieve this goal it is necessary to include neighboring provinces in the analyzes, which will allow to identify their unique species and define their biogeographic limits in a more precise way.

“…The first three families are very diverse and widely distributed in Mexico 29 , their diversity within the limestone karst forest is not the highest, but the species that inhabit this biome tend to be endemic. A study in the Sierra Madre Oriental of Mexico supports the aforementioned and many genera of Asteraceae with a high number of endemic species are restricted to calcareous soils 34 . Similary, in Orchidaceae, a study in Asia 44 suggests that the presence of many limestone karst forest-endemic species of this family, is a generalized pattern.…”

Tropical forests on karstic relief (karst forest) are among the most species-rich biomes. These forests play pivotal roles as global climate regulators and for human wellbeing. Their long-term conservation could be central to global climate mitigation and biodiversity conservation. In Mexico, karst landscapes occupy 20% of the total surface and are distributed mainly in the southeast of the country, along the eastern slope, and in the Yucatan Peninsula. Within each of these areas, the following types of karst occur: coastal karst, plain karst, hill karst, and low-, medium and high-mountain karst. Mountain karst forests cover 2.07% of Mexico’s surface and are covered by tropical rainforests, montane cloud forests, and tropical deciduous forests. It is probably one of the most diverse biomes in Mexico. However, the Mountain karst forest of Mexico has received little attention, and very little is known about it. Here, we evaluate the vascular plant species richness within the mountain karst forests of Mexico. We assembled the first, largest and most comprehensive datasets of Mexican, mountain karst forest species, from different public databases (CONABIO, GBIF, IBdata-UNAM), which included a critical review of all data. The families, genera and species present within the mountain karst forest of Mexico were compiled. Taxa that best characterize the forest of Mexico were identified based on their spatial correlation to this biome. Also, the conservation status of each of them was determined. We explored biodiversity patterns, identifying areas with the highest species richness, endemism centers, and areas of relatively low sampling intensity. We found that within the mountain karst forest of Mexico there are representatives of 11,771 vascular plant species (253 families and 2,254 genera), ca. 50 % of the Mexican flora. We identified 372 species endemic to these forests. According to preliminary IUCN red list criteria, 2,477 species are under some category of conservation risk, of which 456 (3.8 %) are endangered. Most of the Mexican karst forests have been extensively explored and six allopatric, species-rich areas were identified. Compared to other regions in the world, the mountain karst forest of Mexico is one of the most diverse biomes. It contains more species than some entire montane systems in Mexico such as Sierra Madre Oriental, and Sierra Madre del Sur. Also, the mountain karst forest of Mexico is most diverse than similar forests of South America and Asia, even if considering the effect of different sampling areas. The fact that mountain karst forest is covered by some of the most species-rich Mexican forests, in addition to being embedded in areas of high biotic diversity in Mexico, probably contributes to its great floristic diversity. Thus, the mountain karst forest of Mexico is an important source of diversity and shelters a large percentage of the Mexican flora.

Antecedentes: La Zona de Transición Mexicana representa un centro de diversificación y área de endemismo para Sedum subgénero Sedum. Las provincias biogeográficas Sierra Madre del Sur, Faja Volcánica Mexicana, Sierra Madre Oriental y Sierra Madre Occidental (SMO) reúnen la mayor diversidad del subgénero. La SMO destaca por el endemismo de Sedum, por lo que continuar con la exploración y estudio del grupo en el área podría aportar al descubrimiento de especies nuevas. Pregunta: ¿Podría el análisis crítico de la morfología de individuos de Sedum encontrados en exploraciones recientes en la SMO mostrar la existencia de especies no descritas? Especies de estudio: Especies del género Sedum. Sitio y años de estudio: Sierra Madre Occidental, México, durante los años 2019-2021. Métodos: Se realizaron múltiples exploraciones y recolecciones botánicas de Sedum en los estados de Durango y Sinaloa. Los especímenes colectados se sometieron al análisis crítico de su morfología para preparar descripciones y cuadros comparativos entre especies afines morfológicamente. Se obtuvieron, verificaron determinaciones y analizaron registros de Sedum para preparar mapas de distribución en la SMO. Resultados: Se propone a Sedum acaxee como una especie nueva de la sección Pachysedum. La descripción se acompaña de fotografías, un cuadro de morfología comparada y una lista y mapas de Sedum en la SMO. Conclusiones: La alta proporción de localidades tipo (26 spp.) y endemismo (23 spp.) de Sedum para la SMO resaltan la alta diversidad del género en esta provincia y muestran la necesidad de continuar con exploraciones botánicas en este complejo montañoso.
