Adherence to the Mediterranean Diet and Successful aging in Greeks living in Greece and abroad: the epidemiological Mediterranean Islands Study (MEDIS)

Background: Whether older immigrant populations from the Mediterranean region, continue to follow the MD long after they immigrated is not known. Aim: Compare adherence to the MD and successful aging levels between Greeks living in Greece (GG) and Greeks living abroad (GA). Methods: Anthropometrical, clinical, psychological, sociodemographic, dietary and lifestyle parameters were assessed in a cross-sectional manner in a sample of 252 GG and 252 GA. Mediterranean Diet Score (MedDietScore range 0-55) was used to assess adherence to the MD. Successful aging was evaluated with the validated successful aging index (SAI range 0-10). Results: GA presented higher adherence to MD (p < 0.001); they were consuming significantly more cereals, legumes, vegetables, and fruits compared to GG. GG consumed significantly more dairy (3.8 ± 2.9 vs. 1.9 ± 2.2, p < 0.001) and potatoes (2.4 ± 1.6 vs. 1.9 ± 1.5, p < 0.001) compared to GA. Meat ( p = 0.27), poultry ( p = 0.72), fish ( p = 0.68), olive oil ( p = 0.16) and alcohol consumption ( p = 0.05) were comparable between the two groups (all p’s > 0.05). MedDietScore was positively associated with SAI among both groups after adjusting for possible confounders (0.041 ± 0.014, p = 0.003 GG and 0.153 ± 0.035, p < 0.001 GA). Also, legumes, cereals, fruits and vegetables were found to be beneficial for successful aging. Conclusion: Adherence to the MD is associated with higher levels of successful aging among people of the same genetic background living in different environments. However, traditional dietary habits are gradually abandoned in their native countries, when, at the same time, are considered cultural heritage and preserved accordingly among immigrants.

Towards Sustainable Management of Anchoring on Mediterranean Islands—Concession Support Concept

The focus of this paper is to define anchorage management model for concession planning purposes to provide quality support to experts in spatial planning when developing maritime spatial plans. The research aim is to develop an anchorage management model that includes decision and concession support concept. Decision support concept is defined in order to support the processes of identifying potential anchorage locations, their evaluation and comparison, and finally, the priority ranking and selection of locations for their construction. The final step is modelling the concession support concept that includes financial analysis to concession parameters definition. The problem of decision making and concession of the anchorage location selection is complex and ill-structured because of the unsystematic and ad-hoc decisions by all included stakeholders. Additionally, the involvement of several stakeholders’ groups with different preferences and background knowledge, a large amount of conflicting and seemingly incomparable information and data, and numerous conflicting goals and criteria impact final decisions. The proposed concepts overcome the above obstacles in order to enable the construction of anchorages in a way of optimal use of maritime space. The model is tested on the island of Brač, Croatia. The methods used to solve the task are SWARA (The Stepwise Weight Assessment Ratio Analysis) for defining the criteria weights and ELECTRE (Elimination and Choice Expressing Reality) for ranking anchorage locations.

Asynchronous ecological upheavals on the Western Mediterranean islands: New insights on the extinction of their autochthonous small mammals

Comparative studies on extinction scenarios are an invaluable contribution to enhance our understanding of their patterns and mechanisms underpinning them. This paper presents new radiocarbon dates based on specimens of five extinct mammal species from Mallorca and Sardinia. The new evidence permits to reanalyse the extinction dynamics on both islands. Radiocarbon ages directly obtained on bone collagen from these species show evidence of different extinction patterns on Mallorca and Sardinia. For Mallorca the most reliable scenario is a mass extinction of all non-volant mammal species as an immediate consequence of the first human irruption on the island. However, for Sardinia, the extinction of autochthonous mammals lasted over several millennia. The new radiocarbon dates of the last occurrence of endemic mammals suggest a sequence of punctuated extinction events throughout the late Sardinian Holocene. These events are here tentatively related to successive human colonisation waves. The current lack of chronological dates for some Sardinian fossil mammals impedes to outline a more accurate pattern of extinction events. The present paper points that Mallorca have been more vulnerable than Sardinia to the external disturbances introduced by humans. We suggest that the capacity of each island to absorb external perturbations could be related to the island area, the duration of the isolated evolution and the degree of faunal complexity.

Gradients of salinity and plant community richness and diversity in two different Mediterranean coastal ecosystems in NW Sardinia

This study aimed to test if differences in soil salinity, plant richness and diversity were significantly affected by habitat, site and distance from the seashore at three sandy and three rocky coastal sites in north-western Sardinia. Each site has been divided into three belts placed at an equal distance of 50 m from the shoreline. We measured soil salinity using a probe and vascular plants richness and diversity using linear transects at all sites. Average soil salinity varied from 0.115 g/l to 0.180 g/l; it was higher in the rocky habitats than in the sandy ones. A total of 21 species were found per transect/site at the rocky sites and 30 species per transect/site at the sandy sites, with an average of Shannon and Weaver's Diversity Index of 1.8 per each belt at each site. These data confirm that, also in the Mediterranean islands, there are coastal gradients of soil salinity from the seashore to inland areas and that also vascular plant richness and diversity are influenced by the distance from the sea. Soil salinity was strongly affected by the type of habitat, being average at the rocky coasts and negligible at the sandy shores. The site effect was not significant for both soil salinity and plant richness and diversity.

Sustainable and Resilient Management of Underwater Cultural Heritage (UCH) in Remote Mediterranean Islands: A Methodological Framework

The impacts of mass tourism and COVID-19 crisis demonstrate the need for healthy, peaceful, and authentic recreation options, giving prominence to emerging destinations, such as remote Mediterranean islands. These, although endowed with exquisite land and underwater cultural heritage (UCH), are confronted with insularity drawbacks. However, the exceptional land and especially UCH, and the alternative tourism forms these can sustain, e.g., diving tourism, are highly acknowledged. The focus of this paper is on the power of participation and participatory planning in pursuing UCH preservation and sustainable management as a means for heritage-led local development in remote insular regions. Towards this end, the linkages between participation and (U)CH management from a policy perspective—i.e., the global and European policy scenery—and a conceptual one—cultural heritage cycle vs. planning cycle—are firstly explored. These, coupled with the potential offered by ICT-enabled participation, establish a framework for respective participatory cultural planning studies. This framework is validated in Leros Island, Greece, based on previous research conducted in this distinguishable insular territory and WWII battlefield scenery. The policy and conceptual considerations of this work, enriched by Leros evidence-based results, set the ground for featuring new, qualitative and extrovert, human-centric and heritage-led, developmental trails in remote insular communities.

The Bridge Connecting Silkworms to Mosquitos

This chapter relates the history of sugar, a thread that links the Silk Roads, Portuguese sailors, Atlantic islands, endangered seals, the African slave trade, and yellow fever, all because of our physiological need for glucose, which we satisfy with sugar. The chapter tells how from its origin in Southeast Asia, sugarcane, later called “Creole cane” and processing technology moved along the Silk Roads to Western Asia, then to Mediterranean islands. To begin with, Portuguese colonists transformed the Atlantic island of Madeira into a large sugar producer using slave labor until ecological and economic collapse forced production to move to São Tomé, using Angolan slave labor. After Portugal discovered Brazil, colonists took sugarcane with them, creating large plantations and initiating the enslavement and trans-Atlantic movement of millions of Africans. As the chapter shows, sugar production moved into the Caribbean and Central America, and African slave ships inadvertently carried yellow fever and yellow fever mosquito to the Americas.
