Italian marine reserve effectiveness: does enforcement matter?
2008
Marine protected areas (MPAs) have become popular tools worldwide for ecosystem conservation and fishery management. Fish assemblages can benefit from protection provided by MPAs, especially those that include fully no-take reserves. Fish response to protection can thus be used to evaluate the effectiveness of marine reserves. Most target fish are high-level predators and their overfishing may affect entire communities through trophic cascades. In the Mediterranean rocky sublittoral, marine reserves may allow fish predators of sea urchins to recover and thus whole communities to be restored from coralline barrens to macroalgae. Such direct and indirect reserve effects, however, are likely t…
Ecological restoration in contaminated soils of Kokdzhon phosphate mining area (Zhambyl region, Kazakhstan)
2016
Abstract This study provides results of an ecological restoration activity performed in the Kokdzhon phosphate mining of the Zhambyl region (a semi-desert mining area of Kazakhstan). The test area was made by a quarry-hole, about 1.25 hectares wide, that was preliminarily filled with the earthy material of a dump and, subsequently, levelled. The total volume of human transported material (HTM) used was 700 tonnes. Soil samples were taken from 0 to 30 cm depth at 23 sampling sites and several soil quality parameters were determined. In the test area 750 tree species were planted in suitable dug holes: (150 seedlings of Russian Olive; 150 seedlings of Black Saxaul); 150 seedlings of Androsov …
Alberto Burri e l’archeologia del futuro a Gibellina
2021
Il contributo riflette sul ruolo cruciale della relazione tra antico e contemporaneo nella ricerca di Alberto Burri e si focalizza sul Grande Cretto di Gibellina come esempio di archeologia del futuro . A Gibellina Burri ricalca l’antico percorso della citt distrutta dal terremoto attuando un processo affine al restauro archeologico e conserva una traccia della topografia originaria attraverso le forme espressive contemporanee. Il suo approccio da archeologo va dunque inteso come presenza attiva dell’antico, capace di suggerire il dialogo tra la persistenza della storia, affidata alle aree archeologiche di Segesta e Selinunte, e la sua ferita, riscattata dall’arte contemporanea attraverso…
Estimating the non-market benefits of an urban park: Does proximity matter?
2007
Abstract There is increasing and widespread public support for public park provision in urban areas given that they provide an array of different recreational activities enhancing the citizen's quality of life. A contingent valuation survey of 900 randomly chosen inhabitants was undertaken in Valencia (Spain) to estimate the non-market benefits derived from the provision of a new urban park where there is currently an old train station. In conducting our study we distinguished between the districts of the city more and less affected by the project according to the proximity to the future park. Our main finding is that the mean willingness to pay (WTP) is considerably higher for people who l…
La responsabilità dirigenziale al cospetto del giudice ordinario
2021
This paper makes a case for the “contractual-publicist” nature of the managers’ liability regime, although this matter lies within the scope of civil courts’ jurisdiction. Even though the law assigns civil courts the role in deciding disputes regarding potential infringement of public managers claims, these should be considered legitimate expectations (public law) and not rights (civil law). Except for the recovery of the executive jurisdiction of the administrative court, if the administration refuses to fulfil the civil judgment and the public manager spontaneously appeals for compliance, rather than (or together with) the civil one of forced execution.
Autonomie e controlli della Corte dei conti nel quadro dei principi costituzionali e dei vincoli sovranazionali in materia economico-finanziaria
2022
Una riflessione dei controlli sulle autonomie territoriali intestati alla Corte dei conti non può prescindere dal loro inquadramento costituzionale. L’A. prospetta una ricostruzione del controllo come espressione di una funzione neutra e imparziale che deve riposare su precisi parametri costituzionali che ne legittimano l’adozione e di cui va resa una stretta interpretazione: il controllo sulle Autonomie territoriali deve così essere necessariamente una attività tale da avvicinarla a quella giurisdizionale piuttosto che amministrativa. È in tale chiave che deve essere inteso il rapporto fra ausiliarietà di cui all’art. 100 Cost. e controlli sui bilanci ed i rendiconti. L’evoluzione del quad…
Conservation priorities for harlequin frogs (Atelopus spp.) of Peru
2005
Populations of harlequin frogs Atelopus are declining throughout their geographical range. In Peru six of the 11 nominally described species are Critically Endangered, and there are at least 17 undescribed additional forms (all representing apparently distinct species), the conservation status of which is unknown. Most Atelopus taxa in Peru have relatively small geographical ranges, some known only from single populations, and have only a limited chance of survival. Conservation will require: (1) improvement of the faunistic and taxonomic knowledge of the genus, (2) field surveys, including in remote areas, (3) assessment of all species and populations for chytridiomycosis and research on t…
