Накратко на български

Взаимоотношенията между колибритата и растенията помагат да се разберат характеристиките на видовете, които поддържат структурата на екосистемата. Това е важно, за да се предвиди как глобалните промени влияят върху опрашването, биоразнообразието и производството на храна.

Construct and Collapse: Self-emergence and dynamics under global-change scenarios of mutualistic systems

Ongoing global change is driving many species to extinction. Natural ecosystems are composed of many species embedded in complex webs of interaction. Changes in the distributions, phenologies, and abundance of one species may have cascading effects on the rest of the community. This is particular worrying regarding nature's contributions to people, such as pollination. The disruption of pollination interactions is likely to have a large impact in ecosystem biodiversity and food production. But only with a deep understanding of the mechanisms driving such species interactions we will be able to forecast their response capacity to global change. By studying interaction networks we have seen that not all species in the ecosystem have equal importance - some have a more central role in the network, maintaining the general structure and functionality of the community. Therefore, the correct identification of these central species is a useful first step in order to delineate strategic and efficient conservation practices. CoCo's overarching goal was to use a well-studied pollination system (hummingbird-plant interactions) to identify the traits associated with central hummingbird species (e.g. those with highest conservation priority). With that information, we aimed at anticipating species importance in other communities based on species traits.

Цел на проекта

To move ecology towards a more predictive body of theory to anticipate how biodiversity and ecosystem functioning may respond to anthropogenic perturbations, particularly global change, is a foremost challenge for evolutionary and community ecologists in the upcoming years, and a high-priority goal in EU policy. The proposed project “CoCo – Construct and Collapse: self-emergence and dynamics of mutualistic systems under global change scenarios” aims at creating a multidisciplinary and integrative approach which will provide us with a unique opportunity to study relevant aspects of ecological communities which are not well understood. Using an enormous amount of high-resolution data from different ecological disciplines and at a macroecological scale, and complementary state-of-the-art modeling tools, we will create a predictive model able to reproduce the structure of ecological networks. Although highly complex and diverse, the structure of ecological networks can be replicated with simple rules describing evolutionary and ecological mechanisms. This model will then be used, together with the latest climate change projections, to monitor network response to global change perturbations under a number of climate change scenarios. Specifically, we will monitor precisely how individual species react to these perturbations, and explore potential compensatory mechanisms, cascading effects and network breakdown patterns. By exploring these responses, we will be able to identify which network structures and species network roles render a higher resilience to climatic perturbations, and refine the network keystone species concept. We will also be able to find areas and species of higher conservation priority and identify early signs of disruption in other networks. CoCo will create new analytical opportunities, and overcome past methodological weaknesses, situating our findings and methodology in the forefront of the field of ecology.
