“…In modern China, Moraceae includes 12 genera: Antiaris, Artocarpus, Broussonetia, Cannabis, Cudrania, Fatoua, Ficus, Humulus, Maclura, Malaisia, Morus, and Streblus. The diversity of Moraceae has been studied in terms of genetic diversity (Elhawary et al, 2018;Marcotuli et al, 2019;Martins et al, 2021), species diversity (Gardner et al, 2017;Machado et al, 2018;Shi et al, 2018;Pederneiras et al, 2020), and ecosystem diversity (Kong et al, 2020;Dong et al, 2022;Wang et al, 2022). Most studies on diversity in the Moraceae have been conducted for limited species of the genus Morus (Chen et al, 2016;Islam and Rahman, 2019;Hashemi and Khadivi, 2020) and Ficus species (Teixeira et al, 2018;Zhang et al, 2018;Chakraborty et al, 2022).…”

Changes in distribution patterns of economically essential forest species under global change are urgently needed in the scientific forecast, and large-scale spatial modeling is a crucial tool. Using diversity pattern indicators and other data obtained through geographic information systems (GIS) and spatial data on Moraceae species obtained from published data, we quantitatively studied the spatial diversity patterns of genera in the Moraceae in China. The results revealed that the patch richness, diversity index, and total shape index of the genera with multiple species were significantly higher than those of the monotypic genera. Monotypic genera had no spatial diversity and no distribution in patterns of spatial diversity. Maclura had the most concentrated spatial distribution and the lowest distribution area among the Moraceae in China. The number of patches and the total area were the smallest, while the most significant patch index was the highest. Maclura had no spatial diversity. Streblus had the highest patch abundance compared to other genera with fewer species. Streblus had the smallest number of patches and total area of distribution, the lowest spatial distribution, and a small total shape index, indicating its concentrated distribution. The values of the Shannon’s Diversity Index (SHDI) and Simpson’s Diversity Index (SIDI) were the highest, and the spatial distribution was the most diverse among the genera with fewer species. The patch type of Streblus had a more considerable value than other genera, but the number of patches was small, and the total shape index was low. Streblus was primarily distributed in the south of Yunnan, western Guangxi, the west and central parts of Hainan, and southern Guangdong. Most of these areas were mountainous. The temperature decreased with elevation, providing diverse environmental conditions for the narrow-stem genus. Among the Moraceae in China, the spatial distribution of Ficus was the most diverse, with the highest number of patches, patch types, total shape index, SHDI, and SIDI values. The spatial diversity of Ficus could be used as a protected area for Moraceae in China.

The success of restoration projects depends upon the genetic diversity of the implanted species. It is a limiting factor, often because the seed sources are immersed in highly fragmented landscapes. This work was carried out to compare the genetic diversities of the juveniles and the adult trees of Schinus terebinthifolia Raddi in a mixed reforestation area, both in the restoration process and in the remaining natural area in the Atlantic Forest. Through ve SSR primers, it was observed that the implanted population showed a greater genetic diversity index (He) (0.553 adults and 0.505 juveniles) when compared to the wild population (0.487 adults and 0.483 juveniles). It indicated that the forested area was established with individuals of high genetic diversity. There was a reduction of genetic diversity, with the loss of exclusive alleles and maintenance of inbreeding and coancestry in the juveniles of the reforested population. It can be inferred that there was a low gene ow among the fragments. The effective population size in both populations (adults and juveniles) was lower than that recommended for conserving populations in the short and long terms. These results have shown that continuous monitoring of this particular area is of absolute necessity and for applying techniques that can promote the connectivity of the fragments. It would allow for a more signi cant reduction of genetic drift and the persistence of the planted populations.
