Накратко на български

Влиянието на човешката дейност върху биоразнообразието се проучва чрез промените в птичните общности при превръщането на горите в културен ландшафт. Това помага да се разбере как загубата на видове застрашава стабилността на екосистемите и услугите, които те предоставят на хората.

Long-term consequences of environmental changes on biodiversity: incorporating life history traits and time dimension when assessing and predicting the loss of functional and phylogenetic complexity.

Not all species respond equally habitat alteration; rather, some appear to be better adapted to cope with new challenges. It follows that altered habitats should not only sustain fewer species, but also hold less functions. Species loss may lead to a great loss of fundamental characteristics to maintain ecosystem functioning, e. g. morphological complexity. If the adaptations needed to cope with the new challenges are conserved in the tree of life, we also expect the loss of species to induce a loss and homogenisation of phylogenetic diversity, which means a loss of evolutionary history. The loss of biodiversity driven by habitat alteration has a great potential to alter ecosystem functioning and reduce ecosystem stability, and hence impact the long-term sustainability of ecosystem services. With more than half of human population currently living in urban and rural areas and benefiting directly from nature, there is an urgent need for improved understanding of how habitat conversion affects biodiversity components linked to ecosystem functions and services. To advance our knowledge, the main scientific aim of ENVIRON_CHANGE was to assess how differences in tolerance to habitat alteration affect changes associated with species composition and functional and phylogenetic diversities of empirical communities. Specifically, I proposed to investigate the causes and long-term consequences of land use intensification by anthropogenic activities on biodiversity of avian communities. The results obtained from ENVIRON_CHANGE for now highlighted the complex consequences that the transformation of native forests into anthropogenic landscapes has on biodiversity. We provide an important avenue for future research by offering a general picture of the impact that human activities have on biodiversity, allowing to better guide management decisions based on species functions linked to ecosystem functioning and services rather than species number alone.

Цел на проекта

Not all species equally respond to environmental changes, and some are better adapted than others to cope with the new challenges. The loss of functional and phylogenetic diversity driven by habitat loss has a great potential to alter ecosystem functioning and reduce stability, and thus impact the long-term sustainability of ecosystem services. Previous assessments on the causes and consequences of biodiversity loss due to human activities commonly adopted a space-for-time substitution approach to quantify the impacts of habitat alteration, but the impacts on ecosystem functions and evolutionary history over time still remains to be uncovered. I propose to advance the knowledge by using a multidisciplinary approach that combines long-term monitoring and survey, niche analysis, GIS tools, phylogenetic comparative analyses and ecological modelling to understand why certain species are better prepared to respond to environmental changes than others, and how the spatiotemporal variation in responses to habitat changes alters the structure of communities in terms of functional and phylogenetic diversity. Building on classic life history theory and modern theoretical and empirical work, I intend to integrate autoecology and community ecology to investigate the causes and long-term consequences of urbanisation and agriculture to the biodiversity of avian communities. The outcomes will provide us a general picture of the impact of land use change on biodiversity, allowing to better guide management decisions, and may also allow us to assess the extent to which functional diversity is more protected in species rich assemblages. I propose to develop this project under the supervision of Professor Daniel Sol, an international reference in life-history theory and responses of organisms to rapid environmental changes. We will work together at the Centre for Ecological Research and Applied Forestries - CREAF, located at the Universitat Autònoma de Barcelona, in Spain.
