“…Additionally, a habitat suitability layer was created specifically for C. guatemalensis. To build this layer, information about the reproductive phenology and physiology of the species reported by Pozo-Gómez et al (2019, 2020 was used. This included ideal conditions for reproductive effort (number and size of fruits), reproductive potential (number and size of seeds per fruit, health and viability of seeds), and reproductive success (germination rate).…”

“…This included ideal conditions for reproductive effort (number and size of fruits), reproductive potential (number and size of seeds per fruit, health and viability of seeds), and reproductive success (germination rate). For the construction of the habitat suitability layer, we compile all the occurrences reported by Pozo-Gómez et al (2019, 2020, which were filtered, keeping only those where they reported the maximum values of reproductive effort, reproductive potential, and reproductive success. Only 20 occurrences that included these attributes were used.…”

“…Currently, it is under "Special protection" by Mexican law (SEMARNAT 2010) because there are no legal provisions for its use. Because it is a species used for multiple purposes, its availability is of great significance to diverse rural communities that count on it for construction, as firewood, as a live fence, or because of its medicinal properties (Pozo-Gómez et al 2019).…”

Background: The inclusion of information on the phenology of any given species can significantly improve the resulting of potential distribution models. Scientific literature does not provide up-to-date information on the abiotic and biotic factors that determine the distribution of Croton guatemalensis, a species native to communities in south Mexico. For the first time, the potential distribution of C. guatemalensis was determined using a model which includes reproductive biology data. Questions: Which bioclimatic and climatic variables most contribute to the distribution of C. guatemalensis? Does reproductive biology data contribute significantly to the prediction of the species distribution? Studied species/Mathematical model: Croton guatemalensis/ Maximum Entropy Modeling Study area and dates: Chiapas, Mexico, January - December 2020. Methods: The MaxEnt 4.4.4 algorithm was used, incorporating 16 variables, including bioclimatic, climatic and elevation. In addition, a habitat suitability layer was built. Results: The model presented a precision of AUC = 0.964 ± 0.004. Eight variables contributed to explain 86.5 % of the potential distribution of the species. According to their contribution to the model, the most important were the seasonality of precipitation, habitat suitability, elevation and April solar radiation. The species was found in the physiographic regions Central America South Mountain Range Subprovince, Central Depression of Chiapas Discontinuity, and Altos de Chiapas Subprovince. Conclusions: The inclusion reproductive biology data of C. guatemalensis contributed to improve the model. This information allows the development of more effective management and conservation plans by identifying the precise regions in which the species is found.

“…Such is the case of Copalchí (Croton guatemalensis), a species whose distribution goes from southern Mexico to Panama, acclimated in South America and the Caribbean at altitudes of up to 1700 meters above sea level (Cardenas, 2006). In, Mexico this native species is considered to have special protection under the Mexican legislation (Secretaría de Medio Ambiente y Recursos Naturales [Semarnat], 2010); it is a species used by local communities as medicine, for use as live fences and poles, as firewood, for the extraction of wood, honey, fodder, or for construction and manufacturing of work tools (Pozo-Gómez, Orantes-García, Rioja-Paradela, Moreno-Moreno, & Farrera-Sarmiento, 2019).…”

“…Notwithstanding the importance of C. guatemalensis in the Zoque Tropical Forest Biological Corridor, its current exploitation is carried out in wild populations without adequate forest management, and in addition there are no scientific studies on its ecophysiology that allow to generate suitable protocols for its reproduction, propagation and proper management (Pozo-Gómez et al, 2019).…”

Croton guatemalensis is a threatened and multipurpose species in communities of southeastern Mexico and Central America. For the first time, its reproductive phenology and its relationship with environmental variables present in four different natural protected areas of the Zoque Tropical Forest Biological Corridor was determined. Throughout a year the flowering and fructification of the species was monitored, the local environmental variables were recorded and fruits and seeds were collected to determine, under a random design, the germination of the seeds and the growth of seedlings in the laboratory and in nursery respectively. In all cases, flowering was presented from July to April, while fructification occurred from March to September, coinciding with the months where the rains diminish considerably. In terms of seed germination, it presented a statistically significant difference between seeds from the four protected areas. The most contrasting results were presented between La Pera and Area Villa de Allende (98% ± 3.84% and 6% ± 3.84% respectively). According to the generalized linear model, soil porosity was the only variable that influenced the germination of the species (the higher the porosity, the higher the percentage of final germination, t = 2.237, P = 0.0503). Because this is the first study on the ecophysiology of C. guatemalensis in southern Mexico, the importance of it becomes relevant when providing fundamental reproductive information for the generation of strategies for conservation, restoration and forest management of the species.
