Land Snail Fauna of “Porţile de Fier” (“Iron Gates”) Nature Park (Banat, Romania)

2014

Abstract The paper presents an analysis of terrestrial mollusc fauna of the “Iron Gates” Nature Park. Various types of habitats (e.g. forests, rocks, riparian areas) and substrates (e.g. limestone, conglomerate, crystalline schist) were analyzed. A total of 45 species of terrestrial gastropods were identified in 17 sampling points, four of which are mentioned for the first time in the area. Six other species cited in the literature were not found. Limestone substrate allows the development of large populations of terrestrial gastropods, but the specific diversity is larger when it is associated with a forest habitat. The current legal and illegal exploitation of limestone threatens the moll…

Hotspots in cold climate: Conservation value of woodland key habitats in boreal forests

2011

The concept of Woodland Key Habitats (WKH, small-scaled presumed hotspots of biodiversity) has become an essential component of biodiversity conservation in Fennoscandian and Baltic forests. There have been debates over the importance of WKHs in relation to the conservation of biodiversity in production forests. We applied a systematic review protocol and meta-analysis to summarize knowledge on comparisons of biodiversity qualities, such as dead wood and species richness, between WKHs and production forests in relevant countries. We also summarized the knowledge on the impact of edge effects by comparing WKHs surrounded by production forests to WKHs surrounded by clear cuts. Studies had bee…

Systemic silviculture and Mediterranean forest complexity: the need for a new paradigm in forestry

2011

La crescente minaccia di riduzione, semplificazione e scomparsa dei fondamentali caratteri di diversita biologica che caratterizza l’ambiente mediterraneo, e segnatamente le sue formazioni forestali, rende necessario rivedere le strategie di intervento colturale e gestione. In passato hanno prevalso, in specie nei boschi pubblici, forme di gestione e di applicazione della selvicoltura alquanto semplificate e volte a massimizzare soprattutto la funzione produttiva e a “normalizzare “ le formazioni forestali. Viceversa emerge sempre piu chiaramente la complessita dei sistemi mediterranei. Pertanto e necessario uscire dagli schemi preordinati e adottare un approccio che comprenda e rispetti ta…

Assessing physical surrogates for biodiversity: Do tributary and stream type classifications reflect macroinvertebrate assemblage diversity in runnin…

2006

Landscape classifications are increasingly being used in conservation planning and biodiversity management, although there is a dearth of studies actually showing concordant patterns between such classifications and biodiversity. We studied the utility of tributary and stream type classifications in accounting for the variability of invertebrate biodiversity in a boreal drainage system. We found that only weak, although significant, differences existed between the studied three tributaries and four stream types in macroinvertebrate assemblage structure, species distributions, and taxonomic richness. Further, the classification strengths, calculated as mean within-group-similarity minus mean…

Geoconservation in Sicily (Italy): the Example of the Isola delle Femmine (Palermo)

2022

Abstract The Regional Administration of Sicily recently erected Isola delle Femmine—a small island of the Tyrrhenian Sea, close to Palermo—as a geosite. A detailed geological survey has been carried out in order to define the most important geological features of the island together with the development of a new geological map based on topographic data and a digital model at 1:2.000 scale specially processed. Finally, a geological pathway through the island has been traced and illustrated. The geological substrate of Isola delle Femmine consists of a Mesozoic carbonate succession belonging to the Panormide Carbonate Platform. Two lithostratigraphic units have been differentiated. The lowest…

Social Tourism and Healthy Ageing

2015

Recent research in social tourism notes possible links between tourism participation and improvements in health. However, there is a lack of quantitative evidence concerning the potential links between tourism participation and self-reported health amongst older people. An ageing society requires measures to promote independent living and enhance older people's quality of life. This paper provides evidence that older tourists are more active and healthy than non-tourists, from a study comparing health perceptions amongst Spanish older people. The results provide tentative conclusions of causal relationships between tourism and dimensions of physical and mental health through a Structural Eq…
