Anna Traveset

Anna received her BS in Biology from the University of Barcelona and her PhD in Biological Sciences from the University of Pennsylvania. Her research focuses on the study of plant-animal interactions in terrestrial ecosystems, which she examines both from an ecological and an evolutionary perspective. She is especially interested in (1) determining to what extent such biotic interactions are important in maintaining biodiversity and ecosystem functioning, and (2) assessing how such interactions are threatened by different drivers of global change, mostly alien invasive species and global warming. She works mostly on insular ecosystems, although she also collaborates with colleagues doing research in continental areas.

Current PhD Students


Pau Colom

Graduated in Environmental Sciences (Universitat de Girona) and Master in Terrestrial Ecology and Biodiversity Management (Universitat Autònoma de Barcelona). He began his PhD in 2018 at the LAB which focuses on the study of the butterfly communities in the Balearic Islands. In particular, his research integrates demographic and phenological analyses and the study of butterfly-plant interaction dynamics with a biogeographic perspective and in a global change scenario. He participates in national (DEPICT) and local (BARRANCS and STOP-INVAS) research projects and collaborate in a butterfly citizen science project (CBMS).

Raquel Muñoz

Raquel was graduated in Biology (University of Murcia, Spain) and studied a master's degree in Biodiversity and Conservation Biology (UPO-EBD-CSIC, Sevilla, Spain). Currently, she is doing her PhD in our lab, funded by the Spanish government (FPU grant). Her goal is to unravel the joint impact of two invasive herbivores, the Neotropical moth Paysandisia archon and dense goat populations, on the interactions between the endemic Mediterranean dwarf palm and subsequent animal associates (pollinators, seed dispersers, seed predators, herbivores).

Laura Gomez

Laura graduated in biology at the Pontificia Universidad Javeriana, Bogotá, Colombia and studied her master in Biodiversity and Collection Management at the Technische Universität Dresden, Germany. She joined our lab to pursue her PhD, framed under the IslandLife project, funded by the European Research Council (ECR). Specifically, her goal is to study the connection between ecosystem functioning and pollination networks. She aims to do this by studying 1) the impact of rats on pollination networks and 2) how diurnal and nocturnal pollination networks are integrated. She will develop her research on the Seychelles archipelago.

Sandra Hervías

Her main research interest is in studying species interactions on islands to frame conservation problems. Specifically, she investigates the causes and consequences of global changes, such as the impact of biological invasions or the loss of a keystone species, on important ecosystem functions, particularly seed-dispersal and pollination. Currently, she works as a postdoc at IMEDEA for the project ISLET-FOOD WEBS. It aims at studying the food web structure of small island communities and identifying the tipping point beyond which ecosystem functioning can collapse due to a disturbance.


Isa Donoso

Isa is a community ecologist working at the interface of empirical and theoretical ecology. Her main research interest is to understand the effect of plant-animal interactions on ecosystem functioning under anthropogenic impacts, such as habitat  loss and species defaunation. After three years as a Humboldt fellow in Germany, she has joined IMEDEA with a postdoc fellowship of the Balearic Government to evaluate the consequences of climate change for seed dispersal in insular plant communities. Her work combines empirical trait-based studies of seed-dispersal networks, with extinction models to develop potential future scenarios of ecological communities and ecosystem functions. As part of the research team of the project DEPICT, she will also work on deciphering island ecological complexity and its response to global change.

Marta Quitián

She is interested in how environmental factors shape species interactions and hence ecosystem dynamics. She study the impact of human activities on ecosystem functions emerging from mutualistic plant-animal interactions.  Using ecological network analysis and trait-based approaches (i.e. functional diversity indices and functional trait space projections), she detect disruptions on ecosystem functioning. In the past, she focused on seed dispersal and investigated the impact of habitat fragmentation on mutualistic interactions among frugivorous birds and fruiting plants across an elevational gradient in a tropical mountain forest of Ecuador. Her current research focuses on pollination and employs ecological network analysis to assess the impact of habitat loss and invasive species on the pollination networks of the remote Ogasawara islands in Japan.


Alba Costa

Alba is an ecologist interested in understanding the effects of anthropogenic stressors on mutualistic and antagonistic species interactions at the community level. More specifically, she studies how invasive species and global change influence species-interaction networks on islands with the aim of disentangling how to achieve an effective restoration of native biodiversity and ecosystem functioning. After finishing her PhD at the University of Exeter, she has joined the IMEDEA as a postdoc within the European Research Council (ERC) project IslandLife to understand the complexity of ecological interactions on islands and evaluate their vulnerability to global change.

Silvia Santamaría

Her research interest is to understand the ecological mechanisms underlying the structure of plant-pollinator networks. In particular, her research has focused on the evaluation of the effects of networks structure on their robustness, as well as on the functional interpretation of plant-pollinator networks structure in alpine plant communities. Currently, as a postdoc at IMEDEA, she collaborates in the BiodivErSA Project FUNgreen. This project assesses the functional response of pollinators to restoration of species-rich semi-natural grassldans in Europe.

Island biologists from around the world are involved in this project aimed at gathering and jointly analysing information about frugivory and seed dispersal on island systems.  She is currently a JdC postdoc at UMIB (Unidad Mixta de Investigación en Biodiversidad) in Oviedo, Spain. 

Juan Pedro González-Varó

Juanpe started collaborating with Anna in 2008, during his PhD. Together they worked on (i) differences in pollen limitation and inbreeding depression among individual plants; (ii) seed dispersal disruptions; and (iii) the importance of intraspecific variation for the establishment of “forbidden” ecological interactions. During his postdoctoral stay at the Terrestrial Ecology Group in 2018, he  collated information on fruiting phenology and timing of bird migrations in European seed dispersal networks.

Stay at PhD student. (October 2018-September 2019)


His investigations are focused on plant-pollinator interactions in tropical systems since his undergraduate studies, at the University of Campinas. He is for a research stay of his PhD at IMEDEA in Anna Traveset's group. Currently, he is applying the coexistence theory to understand the dynamics of a tropical mountaintop plant-pollinator community and network tools to investigate how pollination interactions affect plant fitness of a Mallorca dune ecosystem.

He is a Biologist specialized in the topic of applied pollination ecology. His investigations are focused on the management of bees and the agricultural environment to improve pollination and food production in pollinator dependent crops. Agustin is a Research Assistant at the CONICET – National Scientific and Technical Research Council in Argentina, and he is visiting Anna’s Lab. to investigate almond pollination.

Haruko Ando

Stay at Post doct. (April 2021-September 2021) 


She finished the PhD in the Graduate School of Agriculture, Kyoto University, Japan, and now working as a researcher in the National Institute for Environmental Studies, Japan. Her research interests are adaptation of birds in island environment and consequent ecological role of them. She mainly work on oceanic islands in Japan using genetics and field work approaches to answer above questions. In Spain, she stayed in Canary Islands and Balearic Islands for one year in total to conduct seed dispersal studies about the birds which are not common in mainland as seed dispersers. In IMEDEA, she evaluated the seed dispersal pattern of olives by seagulls using the GPS tracking and retention time data.
