“…Taxonomic diversity is the total number of recorded bird species within each survey patch, and species abundance is the average number of individuals counted across all surveys at a plot. Based on weight, migration, nesting and foraging strategies and diet (Lee & Park, 1995), each species is assigned to different functional groups according to eld observations and expert opinions. Diet guild was assigned based on the main foods eaten in the breeding season.…”

With a worldwide expansion of urbanization, the conservation of urban biodiversity is attracting growing attention. It is of great signi cance to study the relationship between wildlife and urban landscape. The purpose of this study is to explore the signi cance of vegetation and landscape factors in biodiversity conservation through changes in bird communities. In this study, we focused on 31 parks in the urban area of Fuyang city in the North China Plain. A total of 8795 individual birds from 69 species were recorded. The study found that (a) at the local level, tree diversity and heights are the most important factors contributing to each level of bird diversity, followed by the coverage of shrubs and herbs; (b) at the landscape level, the proportion of woodland has a strong positive correlation with the multidimensional diversity of birds, followed by the patch diversity and percent of grassland. Our results showed that arti cial control of green space structure can effectively increase bird diversity. Increasing the area of urban green space, and at the same time, increasing the proportion of woodland, shrubs, herbs and water in urban parks can provide diverse habitats for birds, thereby improving bird diversity, proves that biodiversity indicators are of great signi cance in landscape planning.

“…In order to examine changes in the physiological and growth responses of Epilobium hirsutum L. according to light conditions, four chambers with different light conditions were installed in the smart farm. As for the selection of light conditions, red and blue lights, which are the most efficient for photosynthesis of plants, and white light, which has been frequently used in recent plant cultivation studies (Lee et al 2019;Lee et al 2020;Saleem et al 2020) were selected. The LED monochromatic lights we used show the maximum number of photons at about 630-660 nm (red light), at 450 nm (blue light), and at 450 nm and 540 nm (white light), respectively.…”

Background: Epilobium hirsutum L. is designated as an endangered plant in South Korea located in Asia, due to the destruction of its habitats through the development of wetlands. Therefore, in this study, in order to find a light condition suitable for the growth and ecophysiological responses of Epilobium hirsutum L., those of this plant under treatment with various light qualities in a smart farm were measured. Results: In order to examine the changes in the physiological and growth responses of Epilobium hirsutum L. according to the light qualities, the treatment with light qualities of the smart farm was carried out using the red light: blue light irradiation time ratios of 1:1, 1:1/2, and 1:1/5 and a red light: blue light: white light irradiation time ratio of 1:1:1. As a result, the ecophysiological responses (difference between leaf temperature and atmospheric temperature, transpiration rate, net photosynthetic rate, intercellular CO 2 partial pressure, photosynthetic quantum efficiency) to light qualities appeared differently according to the treatments with light qualities. The increase in the blue light ratio increased the difference between the leaf temperature and the atmospheric temperature and the photosynthetic quantum efficiency and decreased the transpiration rate and the intercellular CO 2 partial pressure. On the other hand, the white light treatment increased the transpiration rate and intercellular CO 2 partial pressure and decreased the temperature difference between the leaf temperature and the ambient temperature and photosynthetic quantum efficiency. Conclusions: The light condition suitable for the propagation by the stolons, which are the propagules of Epilobium hirsutum L., in the smart farm, is red, blue and white mixed light with high net photosynthetic rates and low difference between leaf temperature and atmospheric temperature.
