Effects of fragmentation on species interactions

A new article analyzing the effects of fragmentation on multi-species interactions is now available. The article is the fruit of a long-standing collaboration with Ainhoa Magrach and Javier Rodríguez-Pérez.

Magrach, A., Rodríguez-Pérez, J., Piazzon, M., Santamaria, L. 2015. Divergent effects of forest edges on host distribution and seed disperser activity influence mistletoe distribution and recruitment. Journal of Ecology 103: 1475–1486.

This is the graphical abstract, available at the journal's website:

We determined the effect of anthropogenic edges on the interactions between three forest-dwelling species: a mistletoe, its host plant and its seed disperser. Forest edges had discordant impacts on the host and the disperser, resulting in increased host availability but reduced seed dispersal. The interdependence of species linked by antagonistic and mutualistic interactions makes them more sensitive to anthropogenic disturbance.


Special issue on Exploitation Barriers

Evolutionary Ecology

Evolutionary Ecology just published a Special Issue on Pollination Exploitation Barriers, edited by Miguel A. Rodríguez-Gironés (EEZA-CSIC) and Luis Santamaría (SEG, EBD-CSIC). 

We are very excited about the issue, which allowed us to summarize our recent work on exploitaiton barriers and frame it in the context of the reseach developed by other groups across the world.

Have a look at the contents below, with links embedded in case you want to sample some of the papers:

Invasive species management in the Seychelles

Lucía Latorre, former postgraduate researcher at the Sptial Ecology Group, works currently as coordinator of an invasive species control project at Praslin Island, Seychelles.

Today's article at the newspaper La Región de Ourense (in Spanish) gives us a hint of her work and plans for the near future:
