The social value of heritage: Balancing the promotion-preservation relationship in the Altamira World Heritage Site, Spain

The social value of heritage: Balancing the promotion-preservation relationship in the Altamira World Heritage Site, Spain

The designation of World Heritage Sites (WHSs) by UNESCO strengthens the international and national image of heritage destinations in the growing market of cultural tourism. Understanding how different stakeholders interpret the value of cultural heritage is one of the most important assets for balancing the promotion and protection of WHSs. This study draws on the case of the Altamira Prehistoric Cave WHS (Spain), whose preservation is under threat and constant debate. It explores factors determining the social value of heritage, namely: existence, aesthetic, economic, and legacy value. In doing so, this paper contributes to emerging debates on heritage management and tourist destinations. Data were collected using two surveys, one focused on visitors, with a total of 1047 valid surveys, and another on the Spanish population as a WHS host community, with a total of 1000 valid surveys. The analysis of these surveys shows how the existence, aesthetic, economic and legacy value dimensions of cultural heritage can build up brands around WHSs. The social-value dimension of cultural heritage therefore affects the market potential of WHSs, whose market potential is closely related to the education levels of a given society. These findings provide valuable information and insights for academics, destination managers and policy-makers in the debate about the preservation and tourism branding of Altamira. This will allow different stakeholders to identify opportunities to develop synergies between tourism promotion and heritage preservation, to both strengthen the brand image of a WHS and preserve its heritage.

Species functional traits and abundance as drivers of multiplex ecological networks: first empirical quantification of inter-layer edge weights

Species functional traits and abundance as drivers of multiplex ecological networks: first empirical quantification of inter-layer edge weights

Many vertebrate species act as both plant pollinators and seed-dispersers, thus interconnecting these processes, particularly on islands. Ecological multilayer networks are a powerful tool to explore interdependencies between processes; however, quantifying the links between species engaging in different types of interactions (i.e. inter-layer edges) remains a great challenge. Here, we empirically measured inter-layer edge weights by quantifying the role of individually marked birds as both pollinators and seed-dispersers of Galápagos plant species over an entire year. Although most species (80%) engaged in both functions, we show that only a small proportion of individuals actually linked the two processes, highlighting the need to further consider intra-specific variability in individuals' functional roles. Furthermore, we found a high variation among species in linking both processes, i.e. some species contribute more than others to the modular organization of the multilayer network. Small and abundant species are particularly important for the cohesion of pollinator seed-dispersal networks, demonstrating the interplay between species traits and neutral processes structuring natural communities.

Food habits of the Macaronesian Sparrowhawk (Accipiter Nisus Granti) on Madeira

Food habits of the Macaronesian Sparrowhawk (Accipiter Nisus Granti) on Madeira

The Eurasian Sparrowhawk (Accipiter nisus) is a small bird of prey distributed throughout Europe and Asia and closely linked to forest environments. It is a predator of a wide diversity of prey, primarily birds (Newton et al. 1986). On the mainland, the male Eurasian Sparrowhawk typically captures small birds (40–120 g in mass), whereas females (nearly twice the mass of males) prey on larger birds (up to 500 g; Opdam 1975, Newton 1978).
