Lessons on Marine Protected Area Management in Northern Boreal Regions from the United States and Norway
2017
In comparison to tropical reef systems, relatively few marine protected areas (MPA’s) exist in temperate or subarctic systems (e.g., North Pacific and North Atlantic) where species diversity is lower, abundance of individual species is often higher, and many fish species exhibit large amounts of movement during one or more of their life stages, especially as adults. A review of MPA’s in three northern areas—the Northwest Atlantic, Northeast Atlantic, and the Northeast Pacific—indicates that MPA’s can be useful management tools towards fisheries management and habitat conservation. However, achieving fishery goals, such as sustainable use of the fisheries resources, will depend on population…
The Use and Abuse of Sea Resources
2017
As a maritime country, the Philippines is a place of high fish consumption. Many coastal villages are populated by fishermen, who are amongst the poorest of working Filipinos. International comparisons show that the Philippine fisheries sector is mostly characterized by small inefficient fishing vessels, while some of the fishing methods are extremely destructive to the resource. Today, fishing moratoriums must be imposed in some areas to allow the reproduction of the fish. Poaching and illegal fisheries, including by foreign vessels, especially from China, plague the most important fisheries areas. Aquaculture has developed to counterbalance the decline of the natural resource, but it has …
Molluscan assemblages associated with photophilic algae in the Marine Reserve of Ustica Island (Lower Tyrrhenian Sea, Italy)
2000
Abstract Very few studies have addressed the effect of protection on macrozoobenthos in marine protected areas, and particularly for sites in the Mediterranean Sea. In the present study, the molluscan assemblages associated with photophilic algal communities of the Marine Reserve of Ustica Island, were investigated. A survey was carried out along transects from 1 to 15 m in depth, during the spring of 1996 at three different sites, subjected to different levels of reserve protection. Species richness and number of individuals reflected the level of protection, and both variables were significantly higher in the integral (most heavily protected) part of the reserve compared with the less wel…
IL CASO STUDIO DI ALCUNE PGM: IMPLICAZIONI PER LE SPECIE DI LEPIDOTTERI NON BERSAGLIO NELLE AREE PROTETTE SICILIANE
2012
La Sicilia è una delle regioni mediterranee con la maggior biodiversità faunistica e floristica la cui conservazione, potrà dipendere anche da un attento piano di valutazione del rischio derivante dall’introduzione di piante geneticamente modificate (PGM) sugli organismi non target. A tal fine sono state scelte due aree rappresentative di differenti habitat siciliani: il SIC “Raffo Rosso, Monte Cuccio e Vallone Sagana (ITA020023) e il SIC “Capo Gallo” (ITA020006). Sono stati individuati 5 habitat: Uliveto, Bosco misto, Ampelodesmeto, Macchia mediterranea e Macchia mediterranea costiera per valutare il potenziale rischio di introduzione di PGM Bt.

Disentangling the effects of area, energy and habitat heterogeneity on boreal forest bird species richness in protected areas
2009
Aim One of the few general laws in ecology is that species richness is a positive function of area. However, it has been proposed that area would merely be a proxy for energy. Additionally, habitat heterogeneity has been found to be an important factor determining species richness. Yet the relative importance of those relationships is little known, and it is still unclear how they are brought about. We aimed to dissect which factors drive the species richness of boreal forest birds, and to identify the most probable mechanisms. Location Forested protected areas in Finland. Methods Using bird line census data collected in 104 protected areas, we ran simultaneous autoregressive models to e…
Improving marine protected area governance through collaboration and co-production.
2020
Marine protected areas (MPAs) socio-ecological effectiveness depends on a number of management and governance elements, among which stakeholder engagement and community support play key roles. Collaborative conservation initiatives that engage stakeholders in action research and knowledge co-production processes can enhance management and governance of MPAs. To design effective strategies aimed at reconciling biodiversity conservation and management of sustainable human uses, it is key to assess how local communities respond to such initiatives and identify the set of contextual factors, institutional, local and individual, potentially affecting these responses. This paper presents the appr…
New Perspectives on Ecological Networks
2017
This chapter introduces the theme of ecological networks, exploring the reference theoretical bases within the International academic debate, and proposing a reflection on how protected areas should no longer be considered as the sum of different components, but rather as a network. In relation to this aspect, the transnational and national models of ecological networks, carried out in the different European countries, are analyzed, through a detailed, updated study of relevant national and international documents. Particular attention is given to the European ecological Natura 2000 network that constitutes the official framework for European policies on protected natural areas. The work hi…
Using GIS for management of conflicts in natural protected area in Cindrel mountains
2021
This study reflects the possibility of using the GIS technology for the management and resolution of conflicts between stakeholders in the management of protected natural areas that cover large surfaces, such as Natura 2000 sites. The research is accomplished in Frumoasa site from Cindrel Mountains, where a conflict of a legal nature was analysed, in the extinguishment of which the technology of geographical information systems was used. In this sense, the presence of the species and habitats that are found on the surface of the incriminated forest was analysed and the comparison with the list of species and habitats that was the basis for declaring the surface as a nature 2000 site. In the…
Sea urchin coelomocytes as a novel cellular biosensor of environmental stress: a field study in the Tremiti Island Marine Protected Area, Southern Ad…
2007
The aim of the present study was to investigate on the suitability of the sea urchin as a sentinel organism for the assessment of the macro-zoobenthos health state in bio-monitoring programmes. A field study was carried out during two oceanographic campaigns using immuno-competent cells, the coelomocytes, from sea urchins living in a marine protected area. In particular, coelomocytes subpopulations ratio and heat shock protein 70 (HSC70) levels were measured in specimens of Paracentrotus lividus (Lamark, 1816) collected in two sampling sites, namely Pianosa and Caprara Islands, both belonging to the Tremiti Island Marine Protected Area (MPA) in the Southern Adriatic Sea, Italy. By density g…
Recognition and Support of ICCAs in Italy
2012
The concept of ICCA was introduced and first discussed in Italy during two workshops held in 2004 and 2005. The notion very well fits the tradition domestically known in terms of common properties (CPs) and ‘civic uses’ lands (proprietà colletive e demani civici), a category referring to lands and the natural resources used in common by a community. They include a diversity of governance solutions derived from their different historical recognition. CPs and civic uses lands in Italy achieved recognition under agricultural law and were particularly associated to the agro-forestry and pastoral sector. They have been subject to regulations of restrictions on change of land use and protected by…
