First record of Heptapleurum arboricola Hayata (Araliaceae) as a casual non-native woody plant in the Mediterranean area
2021
I report here the first record of Heptapleurum arboricola Hayata (syn. Schefflera arboricola (Hayata) Merr.) (Araliaceae) as a casual non-native plant throughout the Mediterranean area. I observed the natural regeneration in urban areas at Castellammare del Golfo, a small coastal town in north-west Sicily (Mediterranean Italy). Due to the lack of self-sustaining populations and the short-term observational period, Heptapleurum arboricola should be considered as a casual species according to the classification of non-native plants. The detection of early signs of naturalization of non-native plants is of crucial importance for the management and control of invasive species. The main abiotic …
Achievements, flaws, and future goals of scientific research on green roofs in mediterranean cities: first feedback from ongoing meta-analysis
2022
Current scientific research points out the low number of papers focused on the environmental patterns in Mediterranean urban areas, where green infrastructure is still strongly underrated by scientists as well as by politicians, planners and decision-makers. In this paper, the results of a simple meta-analysis on the topics treated in scientific literature about the Mediterranean green roofs (MGRs) are presented. Our review pointed out the strikingly higher attention paid to building materials, energy efficiency and hydraulics with respect to life sciences (including basic ecology, horticulture, soil, plant and animal sciences) in the target paper selection. In fact, despite the availabilit…
Benefits of Urban Green Space for Improving Urban Climate
2007
Urban settlements transform the natural environment so greatly that people tend to see the city only as an employment site, and economic and cultural center. Thus a growing number of people prefer to reside in greener suburbs or rural areas. This results in increased automobile commuter traffic, accompanied by traffic jams, accidents, stress, and ever more damage to the environment. Concepts of sustainable development or the ecological city represent strategies for changing these negative trends. The purpose for doing so is principally the well-being of a city’s residents. Often this entails bringing more of the natural environment back into the city, because urban green space fulfills seve…
Ecological assessment of developing carbon sequestration in Shenyang, China
2012
Carbon sequestration in urban ecosystems is becoming an international climate change initiative for sustainable development. Drawing upon field work undertaken in the author's native Shenyang, China, this research reports upon the natural process of carbon sequestration from the atmosphere into urban ecosystems. The risks associated within carbon sequestration in urban ecosystems are investigated and utilised the analysis of ecological carbon cycle status and integrated climate policy with reference to the sustainable development of urban planning. The primary method of this paper is the ecologically–based life assessment of urban ecosystems relevant to tackling barriers for developing carb…
