Накратко на български

Връзката между разнообразието на видовете и стабилността на екосистемите се анализира чрез влиянието на климата и почвата върху услуги като производството на храна. Това помага да се разбере как изчезването на местни видове променя количеството и устойчивостта на природните ресурси.

Maintenance of species diversity and the stability of ecosystem functioning

BioFUNC arose from the need to provide sustainable ecosystems services to the society while conserving biodiversity. This is still a particular societal major challenge as current rates of biodiversity is negatively affecting the deliver of several ecosystem services critical to human welfare such as food production, carbon storage and nutrient accumulation. In order to do so, this project identified that there was a gap of knowledge between the known mechanisms promoting the function of ecological communities and the mechanisms determining biodiversity maintenance. More importantly, the project presented an specific methodology and its application to direct experimentation to bring both fields in order to obtain an emerging framework that will allow distinguishing to what extent services we obtain from nature are stable or transient, and which are the change in magnitude of these services due to the local extinction of species. Overall, the main objective of BioFUNC was to establish for the first time mechanistic linkages between the drivers of species coexistence and the processes maintaining high and stable ecosystem functioning. This objective has required unifying two longstanding bodies of research that unfortunately were not previously combined. These are on one hand the importance of species characteristics, climatic variability and spatial heterogeneity for the maintenance of species diversity and on the other hand the consequences of variation in abiotic (climate and soil) and biotic (community composition, species characteristics and their relative abundances) factors for providing stable ecosystem functions.

Цел на проекта

Current rates of biodiversity loss threaten the delivery of a range ecosystem services critical to human welfare. To maintain ecosystem multifunctionality there is a broad consensus that biodiversity must be conserved or restored, but a key aspect of this, which is still poorly recognized, is that ecosystem services can only persist over space and time if ecological communities are stable (i.e. species within communities do not go locally extinct). However, the mechanistic connections between the maintenance of species diversity and the stability of multiple ecosystem functions have yet to be established. Such ecological knowledge is basic to understanding the social and economic benefits of management actions on biodiversity. BioFUNC aims to investigate the effects of the mechanisms maintaining species diversity (niche and fitness differences) on the stability of multiple ecosystem functions. To accomplish this we aim to take a multidisciplinary approach by combining recent advances in ecological theory with plant population models and observational and field experiments, along with structural equation modelling and meta-analytical techniques. Two lines of related research will be pursued: 1) an investigation of the effects of species traits on species coexistence in spatially and temporally variable environments, and 2) an investigation of the effects of species coexistence mechanisms on the stability of ecosystem functioning in space and time. BioFUNC is a collaborative project between IRNAS-CSIC (Spain, beneficiary) and IPS-University of Bern (Switzerland, partner), which foresees three key results. First, developing a toolbox for predicting when ecosystems services are transient or stable. Second, disentangling direct and indirect effects of climate, soil and species traits on biodiversity and ecosystem functioning. Third, predicting the sign and magnitude of a change in multiple ecosystem functions due to the loss of diversity or changes in species composition
