Beware of contagion!
2003
Landscape ecology starts from the assumption that diversity and spatial arrangement of ecosystem mosaics has ecological implications and tries to understand the interactions between diversity and structure of large spatially heterogeneous areas and its ecological functions. This approach implies effective use of earth observation techniques and geographic information systems, enabling a global view of the landscape mosaics. Consequently, a large number of indices has been used to quantify the structure of categorical maps as a surrogate of actual landscapes and correlate them to ecological processes. In particular, the entropy-based contagion index has been extensively used to summarize the…

Chimpanzees surviving in a fragmented high‐altitude forest landscape of the Congolese Albertine Rift
2021
This paper documents a community of eastern chimpanzees (Pan troglodytes schweinfurthii Giglioli, 1872) inhabiting three relict forest fragments situated on the Lake Albert escarpment, down the Ituri highlands, of eastern Democratic Republic of the Congo (DRC). The area explored had a combined forested surface of ±18.15 km2 in 2017, shrinking by 1.2% per year between 2010 and 2015. Between 2015 and 2017, we found 160 chimpanzee nests along 37.6 km of pilot walks, some up to 2,000 m altitude. Another 123 nests logged along 6.7 km transects led to an estimate of chimpanzee density of 4.62 weaned individuals per square kilometer of forest habitat. Camera‐trap images and direct observations rev…
Qanāts and historical irrigated landscapes in Palermo’s suburban area (Sicily)
2020
La città di Palermo e la sua valle circostante sono un importante paesaggio storico irriguo, caratterizzato da strutture idrauliche sotterranee e da una lunga tradizione di sistemi di irrigazione ereditati dalla presenza islamica in Sicilia nel medioevo (IX-XI secolo). La “rivo- luzione verde” islamica ha radicalmente innovato i sistemi di irrigazione siciliani e questo portò all’introduzione e alla diffusione di nuove specie coltivate. Nell’area suburbana di Pa- lermo sono stati indagati 63 infrastrutture idrauliche e tunnel di scolo, classificati in 4 ca- tegorie: 1) qanāts; 2) qanāts ciechi; 3) pozzi collegati; 4) gallerie di scolo emergenti. Que- ste strutture, nonostante alcuni dubbi c…
Vegetation series as a marker of interactions between rural settlements and landscape: new insights from the archaeological record in Western Sicily
2020
[EN] Plant communities are complex and dynamic elements of the landscape, intertwined with both natural factors and human activities. Vegetation series reflect the environmental characteristics of the landscape, but also the anthropic impact, one of the exogenous forces that most profoundly affects the landscape formation process. This paper aims to investigate the interactions between long-term human settlement catchment areas and vegetation series. The case study area of the Sicani Mountains (Central-Western Sicily) proved to be an ideal place to perform GIS-based spatial analysis in order to compare a data set of rural archaeological sites and land units created through the mapping of ve…
A multifaceted field sampling approach for the management of extremely narrow endemic vascular plant species
2022
Extremely narrow endemic plant species (ENEs) are generally connected with micro- refugia characterized by particular environmental conditions. In-depth knowledge of the ecological requirements of ENEs is fundamental to plan appropriate conservation measures. Using cross-cutting technology, this paper gives a multifaceted approach to collect on-site data on the ecology of ENEs, defines the protocols for a correct sampling design and describes the type of equipment, the time and expenditure needed. Our sampling approach is based on two orthogonal transects, long enough to extrapolate the whole ecological gradient across the area of occupancy of the target species. Microclimatic data are reco…
Social participation in shaping their local landscape
2015
Charakter lokalnego krajobrazu w znaczącej części zależy od poziomu świadomości społeczności, która na danym terenie egzystuje. Głównie chodzi tutaj o poczucie własnej wartości kulturowej oraz znajomości chociażby podstawowych zasad ekologicznego korzystania z zasobów krajobrazowych. Głównym celem badań, których wyniki przedstawiono w niniejszym rozdziale było uzyskanie odpowiedzi na ile i w jakim zakresie ankietowani uważają, że mają znaczący wpływ na podejmowane decyzje w dziedzinie szeroko pojętego modelowania otaczającego ich krajobrazu? Stwierdzenie „Myśl globalnie – działaj lokalnie” czy też „Gmina terenem racjonalnego kształtowania krajobrazu” – jak potwierdzają wyniki przeprowadzony…
Il paesaggio nelle scienze sociali
2019
Il capitolo descrive i quattro significati di paesaggio che sono stati recentemente proposti nelle scienze sociali, per concentrarsi sul ruolo del paesaggio come connettore per discipline e studiosi diversi. The chapter describes the four meanings of landscape that have recently been proposed in the social sciences, to focus on the role of landscape as a connector for different disciplines and scholars.
Role of land set-up systems on soil (physicochemical) conditions
2020
Land reclamation and drainage networks represent one of the most ancient human modifications of the Italian soilscape, where tailored land set-up systems were developed in agro- and forestecosystems in three millennia of man’s activity. Most of once manually maintained land settings are currently scarcely working or even disappeared because of the cost needed for their maintenance and the advent of mechanization that have simplified the field organization. The scarce attention to the soil experienced in the last decades, has accelerated soil erosion and flooding events, which entailed high costs in terms of money and human lives, but also caused reduction of soil thickness, water holding ca…
Applying the RUSLE and ISUM in the Tierra de Barros Vineyards (Extremadura, Spain) to Estimate Soil Mobilisation Rates
2020
Spain is one of the largest wine producers in the world, with Extremadura (south-west Spain) being its second-largest producing region after Castilla La Mancha. Within Extremadura, the most traditional and productive viticulture region is the Tierra de Barros, which boasts an annual production of 3×
