Anthropic space and design for all. New knowledge paths for urban planning strategies
2019
Abstract Nowadays city environment shows the presence of a mixed variety of elements, as natural, semi natural and anthropic components that build up both structure and connections of the urban context. This specific structure shapes and directs space and its functions strictly connected with their sustainable potential uses and sustainable development opportunities. The lack of rules and proper planning methods produces inefficient use conditions by resident citizens, entropy, functions' reduction of ecological networks and deep environmental impacts. The consequence comes out to be a great widespread life quality decrease in urban areas. These thoughts lead the authors to rethink the defi…
International Symposium on Greener Cities for More Efficient Ecosystem Services in a Climate Changing World
2018
The idea of garden is expressed, for the first time in history, by the Mesopotamian civilization as early as the IV millennium BCE as drawings and poetry texts showing a wall fencing one single tree. This is the first representation of the idea of sheltering/protecting a tree by human artifacts and, in its simplest form, brings the idea of the tight relationship between horticulture and urban environment. The "jardinu" of Pantelleria, a drystone wall shaped into an open-top tower encircling a single citrus tree, fully matches both in its founding idea and its physical implementation the elemental idea of the Mesopotamian garden. Such traditional growing system, developed in Pantelleria to c…
Towards More Efficient Incentives for Agri-environment Measures in Degraded and Eroded Vineyards
2015
Evaluating the economic damage caused by soil erosion is important. In addition to increasing the awareness of the problem among farmers and policy makers, evaluation of the economic damage caused by erosion can promote the implementation of more sustainable soil management practices. In the present study, we describe a new approach to evaluate incentives for the adoption of agri-environment measure (AEM) in degraded and eroded vineyards. To estimate this incentive, the replacement cost (RC) and the loss of income are calculated when the vineyard is managed with conventional tillage versus a cover crop (AEM). Our findings show that the incentive could range from the loss of income due to AE…
IoT monitoring of urban tree ecosystem services: Possibilities and challenges
2020
Urban green infrastructure plays an increasingly significant role in sustainable urban development planning as it provides important regulating and cultural ecosystem services. Monitoring of such dynamic and complex systems requires technological solutions which provide easy data collection, processing, and utilization at affordable costs. To meet these challenges a pilot study was conducted using a network of wireless, low cost, and multiparameter monitoring devices, which operate using Internet of Things (IoT) technology, to provide real-time monitoring of regulatory ecosystem services in the form of meaningful indicators for both human health and environmental policies. The pilot study w…
Agricoltura di qualità e rete natura 2000: “laboratori” del cambiamento
2011
Through the centuries, rural communities have managed their environment creating a rich landscape diversity. This represents an historical heritage both for the region and for humanity because the "world" itself represents the sum of widespread fragmentation processes following specific laws. The intense socio-economic changes of the last century, the rise of the "global" markets, in particular, have radically changed the landscape configuration and its natural quality across Europe. Natura 2000 network and the network of protected areas are currently the "open laboratories" to test a model of development that is compatible with the priceless treasure such as: species, habitats, landscape a…
Macroalgae transplant to detect the occurrence of anthropogenic nutrients in seawater of highly tourist beaches in Mediterranean islands
2020
In the Mediterranean region, islands are among the most important tourist destinations, being sites of considerable naturalistic, historical and cultural importance. This is highly beneficial for local economies, but may also represent a threat for the environment, especially during the peak season (i.e. summer). Indeed, the sharp demographic increase concentrated in a relatively short period may negatively affect the quality of coastal marine systems and the provision of ecosystem services, producing in turn negative feedbacks on tourism industry. Nevertheless, the assessment of the environmental impact of tourism on coastal seawater has been seldom addressed. Here, we show the results of …
Ground-level predation on artificial caterpillars indicates no enemy-free time for lepidopteran larvae
2017
Lepidoptera is one of the most diverse orders of insects, their larvae are very abundant in many habitats, and frequent prey of various predators. To decrease predation risk, caterpillars developed several means of defence, among them timing their activity to avoid predators (seeking enemy-free time). Although the enemy-free time hypothesis is often invoked to explain caterpillar behaviour, empirical evidence for it is scarce. We tested whether such enemy-free time exists in a temperate forest by comparing predation pressure on artificial caterpillars during day and night on the ground in forest fragments in Denmark. We found a high predation rate, 23.9% d(-1), and higher predation rate at …
Microplastics and the functional traits of fishes: A global meta‐analysis
2021
Over the years, concern about the effects of microplastics has grown. Here, we answered the main question “What are the impacts of microplastics on the functional traits of fish species?” through a meta-analysis. The general impact of microplastic exposure on the functional traits of fishes and specifically on eight variables, namely, behaviour, development, fecundity, feeding, growth, health, hatching and survival was explored. Subgroup analyses were performed to detect correlations between the impact of microplastics and the following factors: species, life stage, habitat, water column habitat, day of exposure to microplastics and microplastic size, type and shape. A meta-regression analy…
MULTIPLE CLIMATE-DRIVEN CASCADING ECOSYSTEM EFFECTS AFTER THE LOSS OF A FOUNDATION SPECIES
2021
Abstract Climate change is evolving so fast that the related adverse effects on the environment are becoming noticeable. Thus, there is an urgent need to explore and understand the effects generated by multiple extreme climatic events (MECEs) on marine ecosystem functioning and the services provided. Accordingly, we combined long-term in-situ empirical observations in the Mediterranean Sea with a mesocosm manipulation to investigate the concurrence of increasing temperature and hypoxia events. By focussing on a foundation mussel species, we were able to detect several cascade events triggered by a mass mortality event caused by stressful temperature and oxygen conditions, and resulting in a…
The impact of climate change on Mediterranean intertidal communities: losses in coastal ecosystem integrity and services
2014
As has been shown for other ecosystems, the ecological and socio-economic impacts of climate change on Mediterranean intertidal habitats are highly variable in space and time. We conducted field and laboratory measurements of cellular, ecophysiological and behavioural responses of selected intertidal invertebrates (mussels, gastropods and sponges) and completed a literature review to determine what is known of socioeconomic consequences of these biological changes. Results suggest significant gaps in our knowledge that may impede a complete understanding of likely impacts (physical, biological, and socioeconomic) and that sufficient data for such an analysis is available only for mussels. A…
