Monitoring of alien aquatic plants in the inland waters of Sicily (Italy)
2020
Updated and reliable data on the presence and distribution of alien aquatic plant species in Sicily are lacking, and there is a need to fill this gap for a proper and efficient management of freshwater ecosystems and biodiversity. This paper reviews the available knowledge about alien aquatic vascular plants in the inland waters of Sicily (Italy). The aim is to provide an updated checklist, as a first step in the study of the impact of those plants on the native species and ecosystems of this Mediterranean island. The paper focuses on the strictly aquatic species (hydrophytes), excluding emergent macrophytes. Four species were listed, all of them free-floating and with American origin. Most…
Hotspots of species richness, threat and endemism for terrestrial vertebrates in SW Europe
2011
The Mediterranean basin, and the Iberian Peninsula in particular, represent an outstanding “hotspot” of biological diversity with a long history of integration between natural ecosystems and human activities. Using deductive distribution models, and considering both Spain and Portugal, we downscaled traditional range maps for terrestrial vertebrates (amphibians, breeding birds, mammals and reptiles) to the finest possible resolution with the data at hand, and we identified hotspots based on three criteria: i) species richness; ii) vulnerability, and iii) endemism. We also provided a first evaluation of the conservation status of biodiversity hotspots based on these three criteria considerin…
Assessment of the Pressure Level over Lentic Waterbodies through the Estimation of Land Uses in the Catchment and Hydro-Morphological Alterations: Th…
2021
The features of lentic waterbodies largely depend on the surrounding environment. Mediterranean coastal lagoons have been historically altered, with their catchment being highly modified for agricultural, livestock, or urban uses. Changes in land uses induce pressures that impact the waterbodies and alter their ecological status. The objectives of this paper were: to develop a methodological approach (LUPLES: Land Uses for estimating Pressure Levels to approach the Ecological Status), to quantify the main pressures on the waterbodies and to forecast the possible impacts of these pressures on their ecological status. Corine-Land Cover maps and Geographic Information System technics were used…
Producción científica, colaboración y ámbitos de investigación en Enfermedades Infecciosas y Microbiología Clínica (2003–2007)
2010
Introduction: Collaboration is essential for biomedical research. The Carlos III Health Institute (the Spanish national public organization responsible for promoting biomedical research) has encouraged scientific collaboration by promoting Thematic Networks and Cooperative Research Centres. Scientific collaboration in Enfermedades Infecciosas y Microbiologia Clinica journal is investigated. Methods: Papers published in Enfermedades Infecciosas y Microbiologia Clinica in the period 2002-2007 have been identified. Bibliometrics and Social Network Analysis methods have been carried out in order to quantify and characterise scientific collaboration and research areas. Results: A total of 805 pa…
Transformaciones sociales y territoriales en el incremento de la movilidad por razón de trabajo en Andalucía
2007
Entre 1991 y 2001, tal como se deduce de la información de los censos de población de ambos años, se ha producido un importante incremento de la movilidad en Andalucía por razón de trabajo, especialmente de los desplazamientos entre municipios cercanos. Este trabajo indaga sobre los factores relacionados como causas, y también como consecuencias, con tal incremento. En primer lugar, los cambios en la estructura sectorial, ocupacional y socioeconómica de la población ocupada. En segundo lugar, la ampliación espacial de los mercados locales de trabajo. Y, en tercer lugar, la evolución de la organización espacial de la movilidad, especialmente de la movilidad metropolitana. La conclusión es qu…
Pest Plant Score of Alien Robinia Pseudoacacia in Rīga (Latvia) and Kaunas (Lithuania) / Svešzemju Sugas Robinia Pseudoacacia Invazitātes Novērtējums…
2015
Abstract Robinia pseudoacacia is an alien tree species that has wide distribution in green areas of Rīga and Kaunas. In recent years, the spread and invasion of this species was observed. The aim of this study was to determine the relative importance of invasiveness of R. pseudoacacia in Rīga and Kaunas. The degree of species invasion was estimated by applying the Pest Plant Prioritization Process, which is based on the Analytic Hierarchy Process method. The results showed that the invasive degree of R. pseudoacacia was near medium (0.4); the present compared to potential distribution rating was medium (0.57) and the social, environmental and economic impact score was very low (0.17). The F…

Application of a model for the evaluation of the “Visitor Satisfaction” in a nature reserve of South Italy
2017
The protected natural area represents an important resource because from it sustainable and long-lasting social and economic development processes can start. In fact, the conservation of biodiversity can help create economic values by using natural capital which, if properly valorised, can help the momentum of local sustainable development and create diffuse welfare in terms of employment and income. To such a purpose, the evaluation both of the demand by those who enjoy the services of a protected area and of the level of satisfaction that visitors draw from their experience becomes a priority. The present study aims at investigating the behaviour and the preferences of the visitors to a p…
