“…However, recognizing the rates of genetic change in a population if it had been isolated, when in reality it is not, is suboptimal in practical conservation. Rather, it is central to understand the effects on the rate of inbreeding from conservation efforts such as maintaining/creating migration corridors to facilitate genetic exchange between populations (Atickem et al, 2013;Bennett, 1990;Cannas, Lai, Leone, & Zoppi, 2018;Ramiadantsoa, Ovaskainen, Rybicki, & Hanski, 2015).…”

Estimation of effective population size (N e) from genetic marker data is a major focus for biodiversity conservation because it is essential to know at what rates inbreeding is increasing and additive genetic variation is lost. But are these the rates assessed when applying commonly used N e estimation techniques? Here we use recently developed analytical tools and demonstrate that in the case of substructured populations the answer is no. This is because the following: Genetic change can be quantified in several ways reflecting different types of N e such as inbreeding (N eI), variance (N eV), additive genetic variance (N eAV), linkage disequilibrium equilibrium (N eLD), eigenvalue (N eE) and coalescence (N eCo) effective size. They are all the same for an isolated population of constant size, but the realized values of these effective sizes can differ dramatically in populations under migration. Commonly applied N e‐estimators target N eV or N eLD of individual subpopulations. While such estimates are safe proxies for the rates of inbreeding and loss of additive genetic variation under isolation, we show that they are poor indicators of these rates in populations affected by migration. In fact, both the local and global inbreeding (N eI) and additive genetic variance (N eAV) effective sizes are consistently underestimated in a subdivided population. This is serious because these are the effective sizes that are relevant to the widely accepted 50/500 rule for short and long term genetic conservation. The bias can be infinitely large and is due to inappropriate parameters being estimated when applying theory for isolated populations to subdivided ones.

“…The methodology proposed by the authors consisting in the evaluation of congruence and convergence between the specific objectives of LCP and SCIMP and in the evaluation of congruence of the respective actions has allowed us to demonstrate how the military enclave of Villaputzu can be configured as semi-common [35], able to configure services ecosystems [36][37] and use.…”

The military areas in Sardinia are around 234 km 2 , which constitutes 59.97% of the national surface affected by military easements. This situation is due to its geographic centrality in the Mediterranean. This contribution evaluates the performance of the Local Coastline Plan (LCP) and the Site Management Plan of Community Interest (SCI) in conditions of military constraint. The case study is the Municipality of Villaputzu where an important coastal military easement and the use of the coast for recreational tourism purposes coexist together through specific planning, a consequence of institutional agreements between the Municipal Administration of Villaputzu and the Ministry of Defense. The evaluation of the congruence of the specific objectives of the LCP and the SCI shows how their combined action favors the environmental enhancement of Sardinia, contributing to the formation of ecosystem services, even in particular conditions arising from military easements. These are sites that pass from the status of 'anti-commons' to 'semi-commons'. In fact, the military release process in Sardinia, together with the promiscuous military and civil use, activates unique governance policies of their kind that find a significant field of application in Sardinia to guarantee a sustainable renewal of economic development of the 'semi-commons' awaiting to become 'commons' 1 .Coastal Use Plan (LCP) and Strategic Environmental Assessment (SEA): scientific coordinator Ginevra Balletto.

“…A recent study [13] gives evidence that recreational attractiveness is very important as a driving force for the inclusion of patches in the Sardinian regional GI. In other words, the contribution of recreational attractiveness, measured through the number of posted images, is particularly significant with regards to leisure-related ES.…”

According to the European Commission, green infrastructure (GI) is conceived as a strategically planned network of natural and semi-natural areas. This definition highlights three important issues: environment protection, ecosystems multifunctionality and ecological connectivity. Building upon a methodology that identifies a Sardinian regional GI in relation to four values (conservation value, natural value, recreational value and landscape value), this study aims at assessing the suitability of areas situated within and outside protected areas' boundaries to be included in the above-mentioned Sardinian regional GI. In relation to conservation value, outcomes reveal a higher suitability of patches situated within protected areas to be included in the regional GI, whereas in relation to the other three values, the behavioral patterns are less evident. These results suggest specific policy recommendations such as mitigation of land-taking processes, increase of Natura 2000 Network's size, accurate identification of landscape goods, and improved accessibility to sites characterized by outstanding natural beauty.
