The link between the structure of interaction networks and the magnitude of ecosystem functions

The relationship between animal biodiversity and the magnitude of trophic-derived ecosystem function is known. However we still lack a clear understanding of the mechanisms underlying this relationship.

We explore this issue by using a network approach, focusing on the interactions between frugivorous birds and fleshy-fruited plants in the secondary forests of the Cantabrian mountains. We set up a large-scale sampling across fourteen landscapes and two years.

We demostrate that, besides frugivore abundance and diversity, interaction complementarity matters for the magnitude of seed dispersal. Namely, those landscapes harbouring more specialized networks received more dispersed seeds.

See the new article in Functional Ecology!

Biodiversity and ecosystem services in apple orchards...  a day to show our results to stakeholders and public managers


Join us in Oviedo on December the 13th to discuss about how important animal biodiversity is for  ecosystem services in
Asturian cider apple orchards. We'll be there with apple farmers and regional public managers (Agriculture, Land Management and Biodiversity), to develop an intense programme of talks and round tables.


We will summarize our recent research on
biological control by birds and pollination by insects, aiming to increase the societal valuation of Biodiversity but also to set up farming policies oriented to make conservation compatible with apple production.


Don't miss the divulgation stuff, like 
posters and brochures on birds and pollinators, that we have prepared for the event!

Research


We focus on ecological interactions to study the role of biodiversity on ecosystem functions. Functions derived from animals' trophic activity, like pollination, seed dispersal, herbivory and insectivory, condition pivotal ecosystem services such as crop production, forest recovery and pest control.

We aim to understand how the diversity of species and the structure of interaction networks drive the magnitude and the stability of ecosystem functions, and how the spatial configuration of landscape conditions the biodiversity-ecosystem function link.

Based on our studies, we seek to develop tools for biodiversity conservation and ecosystem management in the real-world.

Study systems

We work in the highly anthropized ecosystems of the Cantabrian range (Asturias, N Spain). Most of our research has been carried out in montane forests. These forests have  suffered storng habitat loss and large-scale fragmentation from historical times, but they are naturally recovering after pasture abandonment. The forests are dominated by fleshy-fruited woody plants (Crataegus monogyna, Ilex aquifolium, Rubus ulmifolius) dispersed by birds (Turdus sp., Sylvia sp.) and mammals (carnivores). We try to generalize our findings to other temperate forests in the world, looking at similar plant-animal interaction systems in regions like Austral South America or temperate Oceania.

We have extended our research to agricultural ecosystems, working now in the cider apple orchards of central Asturias. These are traditional, environmental friendly crops embedded in a highly variegated mosaic of semi-natural forests, pastures and hedgerows. There, we study the ecosystem services provided by different animal groups like pollinator insects and insectivorous birds.
