New, Rare and Constant Habitats for Endangered Aquatic Plant Communities: The Importance of Microhabitats for Global biodiversity

2019

Natural water reservoirs are very valuable floristic sites, with springs particularly important for the preservation of floral biodiversity. This paper presents, as a case study, a community of water plants that is new to limnocrene karst springs in Europe: Potametum alpini (Potametea), found in Poland. The paper provides the floristic composition and ecological requirements of this plant association, which is rare and endangered in Europe. According to our knowledge, the habitat data presented here are unique as they are published for the first time for this plant community, and thus it is currently not possible to compare them with data from other authors. Our study confirms the importanc…

Restoration of two small Mediterranean lagoons: The dynamics of submerged macrophytes and factors that affect the success of revegetation

2013

Abstract Two small, shallow lagoons newly created from former rice fields in the Mediterranean coast (Albufera de Valencia Natural Park, Spain) were restored by planting several species of submerged macrophytes (Myriophyllum spicatum, Ceratophyllum demersum, Potamogeton spp., Zannichellia peltata and Ranunculus peltatus) in 2008. Charophytes also appeared spontaneously. M. spicatum was the species that dominated both lagoons and almost completely covered their surface. M. spicatum reached a high biomass and displayed a seasonal pattern, declining during the cold season and reappearing in the spring. No submerged vegetation was observed in the lagoons from 2011 onward. The major purpose of t…

Places of ancient agrarian culture : the discovery of a grain pit

2020

The recovery of memory as well as the protection, preservation, conservation and enhancement of the cultural heritage of our territory – both material and immaterial – are the starting points for this multidisciplinary research, which aims to recount a history that has almost been forgotten. We refer to the tradition of agrarian culture, and to the ancient production, commercialization and conservation of wheat: a valuable asset of sustenance for the community that, in centuries past, played a fundamental role for the socio-economic development of our country, particularly for cities overlooking the Mediterranean basin. Several methods and places have been used to store wheat. This study fo…

Holidays? Not for all. Eagles have larger home ranges on holidays as a consequence of human disturbance

2019

Human-wildlife conflicts are the object of raising concern in conservation biology. People living in urban areas are rapidly increasing worldwide and consequently the temporal pattern of occupation of natural areas for recreation is changing as well, resulting in an ever-increasing concentration of people during weekends and holidays. This is particularly evident in affluent societies, where more recreationists visit natural areas on holidays and weekends, causing disturbance to wildlife in the so-called “weekend effect”. Here, we tested the response to disturbance of 30 Bonelli's eagles tracked by high-frequency GPS/GSM telemetry. We analysed daily home-range size, a measure of changing be…

Jute bioblanket as a soil rehabilitation strategy in Sorocaba, Brazil: Soil chemistry and SWOT approaches

2019

Made available in DSpace on 2022-04-29T08:28:27Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-09-01 Soil erosion and the invasion of exotic plant species are major constraints to achieve sustainable development around the world. Currently, we find few products devoted concomitantly to combatting soil erosion as well as the establishment of unwanted exotic plants. In this paper, we introduce a new product, called herein a bioblanket, that protects the soil and impedes the establishment of exotic plant species. This product is of simple design, and to manufacture it, we use two biodegradable materials: jute tissue and grass wastes. We designed this product to combat soil erosion and …

Urban layout, landscape features and pedestrian usage

2007

ACL; International audience; The analysis of the factors which condition walking in the urban environment is an important issue in urban planning. The present work is based on the hypothesis that the landscape, in its entirety, plays a role in encouraging pedestrian movements. The frequency of pedestrian traffic in the streets is analyzed as a function of accessibility and landscape preferences with the help of a conceptual framework. By defining accessibility as the measurement of the integration of the space syntax, preferences are researched using multiple stepwise regression of visual variables. This method has been applied to an area in the city of Lille (France) where the pedestrian f…

Technology and Architectural Heritage: Dynamic Connections

2019

Technological aspects strongly characterise the built environment in both material and immaterial dimensions. The architectural heritage (the built environment that has acquired cultural meanings, without prejudice regarding the age and the scale of observation) offers a peculiar point of view for dealing with this issue. This paper outlines the dynamic connections between technology, the whole idea of architectural heritage and the approaches to intervention. A focus is placed on four main theoretical aspects, the effects of which are also significant on the practical field: the distance from contemporaneity; the concept of Time; reliable conservation; sustainability. The technological evo…

Materialistic values impact on pro-environmental behavior: The case of transition country as Lithuania

2020

Abstract Materialism is becoming a global phenomenon and is increasing exponentially. Lithuania, which has survived a long period of occupation, experienced privatization and goods’ famine is attributed to the transition countries. In terms of materialistic values, Lithuania is not an exception, as material wealth and image are also very important. Thus, the main question of this paper was whether materialistic values could be reconciled with the pro-environmental behavior, which can be considered as one of the main aspects seeking sustainability. According to the Lithuanian representative survey and by applying the approach of structural equation modeling, the results showed that materiali…
