... Desert climatic conditions allow the conservation of gypsum horizons because the low precipitation slows their erosion and intermixing with different soils and greatly reduces the accumulation of organic matter [7]. The physical characteristics of gypsum soils (gypsisols) vary depending on their origin and the Most gypsum communities studied in Mexico are located within the CHIH [5,8,13,34,38] and the SMOr [37,[39][40][41]. Unfortunately, most gypsum outcrops in Mexico are either poorly explored botanically or even unexplored, especially those in the western and southern portions of the country. ...
... This is particularly evident in the region of west central Coahuila, which has some of the most extensive and least accessible gypsum exposures in North America, as part of the Acatita Formation [44]. The flora associated with the gypsum outcrops from the SMOr seems to be better known, mostly due to the fieldwork conducted in Nuevo León by the Hinton family [41] and in San Luis Potosí by Rzedowski [74]. However, our results showed that many areas of the SMOr need more intensive exploration, even in the relatively well-explored states of Nuevo León and San Luis Potosí. ...
Gypsum soils occur around the world, mainly in arid regions. These harsh environments promote unusual flora with high degrees of endemism. Mexico has extensive gypsum outcrops, but their flora has been poorly studied. However, the highest species richness and endemism are expected to be concentrated in Mexico's northern dry regions. To promote the study of this flora and its conservation, we estimate how well sampled it is, quantify species richness, identify centers of endemism, and detect which gypsum outcrops lie within federal protected natural areas (PNA). We conducted exhaustive literature and herbaria reviews to generate a database of botanical records on gypsum soils. The total species and gypsophyte richness were calculated using cell grids. Centers of endemism were identified using the corrected weighted endemism index (CWE). We mapped the gypsum outcrops within PNA polygons. The most collected sites are Cuatro Ciénegas (Coahuila) and Santo Domingo Tonalá (Oaxaca), which also had the highest total species richness. Nevertheless, gypsophyte richness was higher in Cuatro Ciénegas and Nuevo León. The CWE identified seven gypsophyte centers of endemism. Mexico hosts the most diverse gypsophile flora in the world, despite having been only partially studied and collected. The regions with the highest species richness and endemism are unprotected.

Databases of biological collections contain fundamental information for the study of biodiversity, hence the importance of their quality, which includes the data on collectors. For this purpose, a list of the main vascular plant collectors in Mexico was constructed to improve the quality of this information. A total of 3.7 million records of vascular plant specimens collected in Mexico were analyzed from the National System of Biodiversity Information (Sistema Nacional de Información sobre Biodiversidad; SNIB) of the Mexican National Commission for the Knowledge and Use of Biodiversity (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad de México; Conabio) and the database of the National Herbarium of Mexico (Herbario Nacional de México; MEXU) of the Institute of Biology at the National Autonomous University of Mexico (UNAM). A “main collector” was considered anyone with 500 or more unique collection numbers in the database. A total of 610 main collectors were identified, who together contributed 83% of the records of vascular plants collected in Mexico, and a standardized list of their names is presented. The list of names of main collectors of vascular plants in Mexico is a useful tool for the cleaning and extraction of information from biodiversity databases.
... His son James Hinton (1915Hinton ( -2006 often accompanied him on expeditions, and during the 1930s and early 1940s, they made more than 16,300 collections, primarily in the states of Guerrero, México, and Michoacán [1]. Their specimens are widely distributed in numerous herbaria, and at least 621 new species have been proposed on the basis of this material, including five species of Euphorbia L.: E. coalcomanensis (Croizat) V.W. Steinm., E. dressleri V.W. Steinm., E. hintonii L.C. Wheeler, E. linguiformis McVaugh, and E. succedeana L.C. Wheeler [2]. In the case of E. dressleri, it is known only from Hinton's material, and subsequent relocation attempts have been futile [3]. ...
Euphorbia marciae, a new species from the lowlands of the Balsas Depression in southwestern Mexico, is described and illustrated. The species was first collected by the renowned botanist George B. Hinton during his explorations of the area in the 1930s. It is known from only five collections made in northwestern Guerrero and the extreme southwestern portion of the state of México, at elevations from 250 to 610 m. Vegetation of the area is tropical deciduous forest. Euphorbia marciae belongs to Euphorbia subg. Chamaesyce sect. Anisophyllum and resembles E. apatzingana, E. hyssopifolia, and E. nutans. However, it differs from these species in having smooth seeds. The seeds are nearly identical to those of E. pionosperma, an endemic species occurring in the Sierra Madre Occidental of eastern Sonora and western Chihuahua. However, the leaves of E. pionosperma are more conspicuously serrate and have larger stipules. In addition, Euphorbia pionosperma has smaller involucres and involucral appendages. Following IUCN Redlist criteria, E. marciae should be treated as Data Deficient (DD) until the species can be relocated and its populations field evaluated.

As an important research direction of the energy system, the integrated energy system of a park plays an important role in the field of energy optimization and sustainable economic operation. In this study, a low-carbon optimal operation model of the integrated energy system of an industrial park is proposed, considering a controllable flexible load response. First, the typical structure of the integrated energy system of the park and the model of each subsystem are introduced; then, under the premise that flexible electrical and thermal loads can be used for adjustment of energy utilization, a complete dispatch scheme is constructed according to the energy consumption and system operation characteristics of the integrated energy system. Finally, an optimal scheduling model for the combined supply and demand of the integrated energy system is established with the aim of minimizing the total operating cost. For experimental results, the YALMIP toolbox and the CPLEX solver are used to verify the results of the study; simulation results show that the optimal scheduling of controllable loads can effectively reduce the comprehensive operating cost of a community integrated energy system.
Antecedentes: El noreste de México, estados de Coahuila, Nuevo León y Tamaulipas, constituye una región heterogénea que incluye sierras, planicies continentales y llanuras costeras con una infinidad de ambientes, substratos geológicos y gradientes altitudinales que favorecen la presencia de una rica biodiversidad. No existe una síntesis que documente la diversidad florística de esta región.
Preguntas: ¿Cuál es la magnitud de la diversidad de plantas vasculares en el noreste de México?, ¿Cuáles son las familias y géneros con mayor número de especies?, ¿Cómo se distribuye geográficamente esta riqueza florística en toda la región y cuáles son sus elementos más característicos?
Especies de estudio: 7,088 especies de plantas vasculares.
Sitio de muestreo: estados de Coahuila, Nuevo León y Tamaulipas.
Métodos: Se consultó literatura florística-taxonómica sobre la flora de la región y bases de datos de ejemplares para hacer un análisis espacial de la biodiversidad usando celdas de 1° de longitud y latitud. Se calculó la riqueza y el endemismo en la región, los estados y las celdas.
Resultados: Para el noreste de México se reportan 7,088 especies de plantas vasculares, de las cuales 1,767 son endémicas de México.
Conclusiones: El noreste de México registra una diversidad florística particularmente interesante y compleja, debido a que su territorio se ubica primordialmente fuera del neotrópico y porque constituye el límite boreal para muchos elementos de la flora de México.
