The social role of peri-urban forests is diversifying, and this implies that peri-urban forests are redesigned to meet and shape social demands. A key challenge is the integration of the social demands for green spaces with the maintenance of key ecosystem structures and processes as well as the biodiversity of the green spaces. In this study, we report our experience and insights gathered through the implementation of a project targeting a peri-urban forest development near the city of Cluj-Napoca. One key particularity of the project was that it was designed by the city hall in cooperation with a major NGO, and the academic sector joined the project in its second stage, with the aim of mainstreaming ecosystem services and biodiversity within a well-established design concept. After comprehensively assessing the biodiversity and ecosystem services of the targeted forest, we found that the ecosystem supply was strongly related to the tree stand structure and the forestry management ...

ABSTRACT Two spirobisnaphthalenes, namely palmarumycins C2 and C3, were isolated from cultures of the endophytic fungus Berkleasmium sp. Dzf12 after treatment with 1-hexadecene. After addition of 1-hexadecene at 10% to the medium on day 6 of culture, the maximal yields of palmarumycins C2 and C3 were obtained as 0.40 g/L and 1.19 g/L, which were 40.00 fold and 59.50 fold higher, respectively, in comparison with those of the control (0.01 g/L and 0.02 g/L). The results indicated that addition of 1-hexadecene can be an effective strategy for enhancing the production of palmarumycins C2 and C3 in liquid culture of endophytic fungus Berkleasmium sp. Dzf12. Palmarumycin C3 exhibited stronger antimicrobial and antioxidant activities than palmarumycin C2.
