Uncovering Ecosystem Service Bundles through Social Preferences

Ecosystem service assessments have increasingly been used to support environmental management policies, mainly based on biophysical and economic indicators. However, few studies have coped with the social-cultural dimension of ecosystem services, despite being considered a research priority. We examined how ecosystem service bundles and trade-offs emerge from diverging social preferences toward ecosystem services delivered by various types of ecosystems in Spain. We conducted 3,379 direct face-to-face questionnaires in eight different case study sites from 2007 to 2011. Overall, 90.5% of the sampled population recognized the ecosystem’s capacity to deliver services. Formal studies, environmental behavior, and gender variables influenced the probability of people recognizing the ecosystem’s capacity to provide services. The ecosystem services most frequently perceived by people were regulating services; of those, air purification held the greatest importance. However, statistical analysis showed that socio-cultural factors and the conservation management strategy of ecosystems (i.e., National Park, Natural Park, or a non-protected area) have an effect on social preferences toward ecosystem services. Ecosystem service trade-offs and bundles were identified by analyzing social preferences through multivariate analysis (redundancy analysis and hierarchical cluster analysis). We found a clear trade-off among provisioning services (and recreational hunting) versus regulating services and almost all cultural services. We identified three ecosystem service bundles associated with the conservation management strategy and the rural-urban gradient. We conclude that socio-cultural preferences toward ecosystem services can serve as a tool to identify relevant services for people, the factors underlying these social preferences, and emerging ecosystem service bundles and trade-offs

Postcolonial reproductions: disability, indigeneity and the formation of the white masculine settler state of Australia

© 2015. There has been a growing debate within the broad field of postcolonial scholarship which seeks to challenge both its territorial boundaries with the advent of globalization and its limitations when applied to the realm of white-settler societies. The debate has been extremely fruitful in situating emerging scholarship that seeks to extend postcoloniality, its theoretical framing, and the internal processes of social categorization for peoples caught within the nation-state's territorial sphere. Unfortunately, disability and indigeneity remain largely absent from these fresh debates; or when included, are explored as singular fields of analytical inquiry with little intersectional dialogue. With this paper, I aim to extend these nascent debates by critically engaging with both disability and indigeneity as two interlocking sites of (post)colonial nation-state power. To explicate this argument, my analysis focuses on a key historical moment in the Australian experience – the formation of the colonial white-settler society of Australia in its early years (1901–1920s), comparing and contrasting the systems of administrative management of disability and indigeneity. In doing so, the paper reveals the deep materialities of white, able-bodied, masculine, (post)colonial settler rule that bring together disability and indigeneity via gender reproductive controls. The conclusion reflects on the transformative effects of managing transgressive bodies and minds under the white able-bodied settler state and the potential this opens to negotiate practices of solidarity

Genetics and cytogenetics of the potato

Tetraploid potato (Solanum tuberosum L.) is a genetically complex, polysomic tetraploid (2n = 4x = 48), highly heterozygous crop, which makes genetic research and utilization of potato wild relatives in breeding difficult. Notwithstanding, the potato reference genome, transcriptome, resequencing, and single nucleotide polymorphism (SNP) genotyping analysis provide new means for increasing the understanding of potato genetics and cytogenetics. An alternative approach based on the use of haploids (2n = 2x = 24) produced from tetraploid S. tuberosum along with available genomic tools have also provided means to get insights into natural mechanisms that take place within the genetic load and chromosomal architecture of tetraploid potatoes. This chapter gives an overview of potato genetic and cytogenetic research relevant to germplasm enhancement and breeding. The reader will encounter findings that open new doors to explore inbred line breeding in potato and strategic roads to access the diversity across the polyploid series of this crop’s genetic resources. The text includes classical concepts and explains the foundations of potato genetics and mechanisms underlying natural cytogenetics phenomena as well as their breeding applications. Hopefully, this chapter will encourage further research that will lead to successfully develop broad-based potato breeding populations and derive highly heterozygous cultivars that meet the demands of having a resilient crop addressing the threats brought by climate change
