Beta diversity can be measured in different ways. Among these, the total variance of the community data table Y can be used as an estimate of beta diversity. We show how the total variance of Y can be calculated either directly or through a dissimilarity matrix obtained using any dissimilarity index deemed appropriate for pairwise comparisons of community composition data. We addressed the question of which index to use by coding 16 indices using 14 properties that are necessary for beta assessment, comparability among data sets, sampling issues and ordination. Our comparison analysis classified the coefficients under study into five types, three of which are appropriate for beta diversity assessment. Our approach links the concept of beta diversity with the analysis of community data by commonly used methods like ordination and anova. Total beta can be partitioned into Species Contributions (SCBD: degree of variation of individual species across the study area) and Local Contributions (LCBD: comparative indicators of the ecological uniqueness of the sites) to Beta Diversity. Moreover, total beta can be broken up into within- and among-group components by manova, into orthogonal axes by ordination, into spatial scales by eigenfunction analysis or among explanatory data sets by variation partitioning. © 2013 John Wiley & Sons Ltd/CNRS.

The low timber returns of Mediterranean forests, together with their high fire risk, has led to negligent forest management. Absence of management has in turn been blamed for increasing the risk of fire, thus forming a vicious circle of low profitability, little management and high risk of fire. Developing forest planning tools that maximize both economic objectives and fire resistance could help to revive the forest sector in the region and generate long-term fire prevention strategies. In the present study, we simultaneously maximized timber income and the overall fire resistance of the landscape to generate management plans for a typical forest landscape in the Pre-Pyrenees of Catalonia (North-East Spain). The risk of fire was integrated into the economic objective by incorporating potential fire losses in the expected net income. Landscape metrics describing fire resistance were also included in problem formulations. The results show that this approach greatly improves management efficiency in terms of economic profitability and fire resistance. © 2010 Elsevier B.V. Source

The NEWFORESTS exchange program brings together researchers from 5 research institutions: two from public research centres in Spain, Forest Sciences Centre of Catalonia (CTFC) and Centre for Ecological Research and Forestry Applications (CREAF), one French institution, Bio-Archaeology and Ecology Centre (CBAE), and two Canadian Universities (University of Quebec in Montreal, UQAM, and in Abitibi-Tmiscamingue, UQAT) hosting two of the main hubs of the Centre for Forest Research (CEF). During three years, a total of 36 senior researchers will participate in the program with a total of 328 man-months including experienced and early stage researcher, technical and management staff from the different centres. The aim of this proposal is to create a competitive platform at the international level to analyse the responses of forest ecosystems to global changes and integrate current knowledge in sound and innovative forest management and planning approaches. The general objective of the program is to determine how to effectively integrate woodland management (including non-management options) into strategies aimed to adjust and mitigate global change. The program is organized in 5 thematic work packages ranging from the basic understanding of forests dynamics, biodiversity and functioning (WP 1 and 2) to research on interactions between global change drivers determining disturbances regimes (WP 3) and the integration of the gathered knowledge into advanced modelling tools (WP 4) and sound management guidelines at different spatial scales (WP 5). Finally, a project management WP (6) depicts the practical organisation and management of the project. A fundamental aspect of the program is that it stresses not only the responsibility of human society as a major driver of global change, but also recognizes that we have an opportunity to mitigate this change through informed, proper management decisions.

Europe has set a clear and ambitious strategy (Europe 2020 Strategy) to base its economy on a smart, sustainable and inclusive growth. Part of this concept is to initiate the development towards an innovative, resource efficient and bio-based (bio-economy) European economy. Such development should contribute to economic growth and the creation of jobs, while mitigating climate change effects and providing effective responses to address the need for carbon neutral energy. In this context, European forests and the forest-based sector play an increasingly important role in fostering smart, sustainable and inclusive growth in Europe based on the production of eco-services and eco-efficient products from wood and non-wood-based products. Up to now the forest-based sector has been mainly build around wood based products. However, also multipurpose trees and non-wood forest products and services can significantly contribute to the achievement of the set goals. The objective of the STAR TREE project is to provide better understanding, knowledge, guidance and tools to support relevant stakeholders (e.g., forest owners, resource managers, enterprises, decision makers, other public and private entities) in optimising the management of multi-purpose trees and developing innovative approaches for increasing the marketability and profitability of NWFP for a more competitive rural economy. The overall impacts of the project are in the long term to support a sustainable rural development through a stronger utilisation of business opportunities based on non-wood forest products and multipurpose trees. This will particularly benefit the rural population as much as land owners and companies through a more competitive and robust rural economy and a better quality of life.

SIMRA seeks to advance understanding of social innovation (SI) and innovative governance in agriculture, forestry and rural development (RD), and how to boost them, particularly in marginalised rural areas across Europe, with a focus on the Mediterranean region (including non-EU) where there is limited evidence of outcomes and supporting conditions. These objectives will be achieved by: 1. Developing systematic frameworks: a) theoretical - for improved knowledge of the complexity of SIs and its dimensions, and its impact on unfolding territorial capital; b) operational - based on a trans-disciplinary coalition (researchers and practitioners) to advance understanding of preconditions and success factors (e.g. instruments, incentives etc.) for implementing/operationalizing SI. 2. Creating a categorisation of SIs which encompasses the specificities in terms of social priorities, relationships/collaborations etc. and serves as an instrument to explore reasons why regions with similar conditions display diverging paths and to turn diversity into strength. 3. Creating an integrated set of methods to evaluate SI and its impacts on economic, social, environmental, institutional and policy dimensions of territorial capital. 4. Co-constructed evaluation of SIs in case studies across the spatial variation of European rural areas, considering which components of territorial capital foster and, or mainstream RD. 5. Synthesis and dissemination of new or improved knowledge of SIs and novel governance mechanisms to promote social capital and institutional capacity building and inform effective options/solutions for shaping sustainable development trajectories. 6. Creating collaborative learning and networking opportunities and launching innovative actions at different/multiple scales, with continuous interactions among researchers, knowledge brokers and stakeholders to foster and mainstream SI, leaving a durable legacy.
