“…To evaluate the relative importance of the predictors as drivers of forest color indices, we calculated the effect of the parameter estimates for each explanatory variable relative to all parameter estimates in the model [62]. The following three identifiable variance fractions were examined: (1) meteorological variables, (2) park feature variables, and (3) human activity variables.…”

Preserving the authenticity of forest colors is essential to highlight regional characteristics and promote the sustainable development of forest landscapes. However, the factors and mechanisms influencing forest color remain unclear. We quantified 1422 forest color images from 43 parks across seven biogeographic regions in China to capture the forest color composition among regions. A generalized linear mixed-effects model was used to analyze the effects of meteorological and anthropogenic disturbance factors on forest color. Meteorological factors included accumulated sunshine hours, average temperature, accumulated precipitation, frost-free period, average wind speed, and average air quality index. Anthropogenic disturbance factors included park feature indicators (area, elevation, and perimeter-area ratio) and human activity indicators (distance to urban areas, building density, and road density). We calculated p-values and relative effect estimates to determine the sensitivity and degree of sensitivity of color to each factor. The results indicated the following: (1) forest color composition varied significantly among different regions in China with variations observed particularly in the proportions of primary (green), secondary (yellow and yellow-green), and accent colors (orange and blue-green); (2) forest colors were sensitive to all meteorological factors; (3) orange, yellow, purple, and red were all sensitive to anthropogenic disturbance factors; and (4) forest accent colors were more strongly influenced by anthropogenic disturbance factors, particularly park features. To protect the authenticity of forest colors, it is necessary to avoid excessive borrowing of forest color schemes from different regions, control park features, reduce building area within the park buffer zones, and optimize park tourism routes.

“…As host plants of these species are always observed at the site, this is probably not the factor at play. Most butterflies require a habitat with a diversity of space adapted to all stages of development, including host plants for larval development, availability of litter, sources of nectar for adult and an area for warming [59][60][61]. These habitats are characterized by the vegetation and the structure of their strata [60].…”

Urbanization is one of the main threats to biodiversity. However, some urban green spaces could act as refuges for urban fauna if the composition of the flora were less horticultural and if a less intensive management strategy is adopted. Among the taxa, butterflies are experiencing a strong decline from European to regional scales. An ecological engineering project based on a plantation of host and nectariferous plants backed up by a well thought out management strategy was carried out in Marseille at the Parc Urbain des Papillons (the Butterflies Urban Park). We assessed its effectiveness by comparing the butterfly communities in this park before and after the engineering work, and we compared it to a neighboring wasteland with natural habitats. After 12 years of the project, the results show a significant change in the species composition. The species richness greatly increased from 25 to 42 species. Some specialist species we targeted appeared, and their numbers increased from one to five. However, three Mediterranean species are still absent compared to the wasteland with natural habitats. As the plant palette used and the management strategy implemented enabled us to significantly increase the number of species, we now plan to work on the structure of the vegetation.

“…Logging can also impact species indirectly through changes in microclimate and therefore resource availability, an important determinant of species presence across plant and animal taxa (Boyle et al, 2021;Zellweger et al, 2020). Microclimatic characteristics and diversity are in turn linked to the physical structure of the tree community (Han et al, 2022) and are consequently highly sensitive to selective logging (Aleixo, 1999;Thiollay, 1992).…”

The synergistic impacts of climate change and habitat degradation threaten tropical species worldwide. However, how species’ microclimatic niches affect their demographic and phenotypic responses to anthropogenic change remains poorly understood. Using an 11-year mark-recapture dataset from primary and selectively logged forest in the Eastern Himalaya, we investigated how species-specific microclimatic niches predicted body mass and survival trends in understorey insectivorous birds in each habitat. Overall, logged forest is hotter and drier than primary forest, and the arthropod prey community shows shifts in composition upon selective logging. For understorey insectivorous birds, the degree of dissimilarity between species-specific primary and logged forest microclimatic niches was strongly and negatively correlated with survival and less strongly with body mass trends in logged forest. Microclimatic niche shifts in response to anthropogenic habitat modification can impact both demographic rates and body condition, crucial for population persistence. Our results can inform prompt, targeted conservation efforts toward the most threatened species in a warmer and more degraded world.
