I comple‍‍‍ted my BSc and MSc in Evolutionary Biology at the University of Padova (Italy). For my Master thesis I moved to Jyväskylä, Finland, where together with Johanna Mappes and Janne Valkonen I studied the efficacy of butterfly eyespots in deterring predators.

While handling the behavioural data I collected, I became fascinated by the creative ways of analysing and interpreting complex datasets: I found my true call. In the seek for novel quantitative approaches and challenges I started my PhD with Andrés on a versatile and interesting system: the Trinidadian guppy Poecilia reticulata. As a PhD candidate at the University of Jyväskylä, I study how population density at different scales (local and global) affects dispersal, and how this, together with dispersal evolution, shapes the spread of populations through space

I continue my work on animal coloration and anti-predator defences, collaborating with Johanna Mappes and Kate Umbers (U. Western Sydney, Australia) in a project on the deimatic (startle) display of the Mountain katydid, Acripeza reticulata.

Licia defended her PhD in 2015 at the Université Pierre et Marie Curie (Paris) under the supervision of Vincent Bretagnole , Gerard Rocamora, and Andrés López-Sepulcre. She studied the population biology of two competing species of shearwater (Wedge-tailed Puffinus pacificus, and Tropical P. bailloni) that breed on Aride Island (Seychelles). She will soon be travelling back to Aride Island to take charge of the recovery program of the endangered Seychelles magpie-robin (Copsychus sechellarum)

Dr. Andrés López-Sepulcre CNRS Researcher (CR1)

After undergraduate studies at the University of Barcelona and the University of Glasgow, I did my PhD at the University of Helsinki modelling the interaction between space-use behaviour and demography, under supervision of Hanna Kokko and Ken Norris

During my first PostDoc at the University of California, Riverside, David Reznick, collaborators, and I established a long term evolutionary experiment in Trinidadian  guppies to study the feedbacks between ecology and evolution. I carried out a second postdoc at the École Normale Supérieure de Paris (with Regis Ferriére) before becoming a tenured CNRS researcher at the Institute of Ecology and Environmental Sciences of Paris (iEES). I am also a visiting researcher the University of Jyväskylä.

I study several facets of eco-evolutionary theory: how acknowledging the feedback between ecological and evolutionary processes (at different scales) can help us understand nature. I am particularly interested in the challenges of integrating theory and ecological data, which makes me keen on statistical modelling and philosophy of science.

Guppy Project Field Internships in Trinidad

We often need interns to assist the monitoring of our long-term evolutionary experiment, including the monthly capture-mark-recapture census of guppies. The work includes long hours in the field and laboratory. We seek interns who are entertaining the possibility of pursing graduate studies in some area of ecology and evolution and who wish to gain some field research experience before entering graduate school. Research takes place in semi-remote areas of Trinidad sometimes under bad weather conditions. Applicants must be able to live and work well with others. Work involves carrying heavy packs over slippery and steep terrain. Applicants must be in good physical condition and be able to meet the demands of field research under these conditions. Ability to drive a standard transmission vehicle is desirable but not required. Applicants with first-aid/first responder training, skills in automobile maintenance, and construction skills are highly desirable. Please address these skills when applying. Interns will be required to spend a minimum of 3-months in Trinidad, with possibility of extension. We cover all travel and living expenses and provide housing.

Please see the Guppy Project website cnas.ucr.edu/guppy for more information on the project and access to reprints. Our video menu includes a “guppy censuses” submenu that details the main tasks associated with the internship. For a quick impression of a day’s work, check out the great videos by our previous intern Sam Swanson.

Please contact David Reznick (gupy@ucr.edu) or Andrés López-Sepulcre (alopez@biologie.ens.fr) for information on availability of positions. Demand varies throughout the year. To apply, send cover letter, CV and the names, phone numbers and e-mail addresses of three or more professional references to. At least two of the references should be academics.  

If you have funding or are interested in applying for funding as an undergraduate, Masters, PhD  student, or postdoc, and want to discuss some project ideas, please contact me at alopez@biologie.ens.fr . Below are some opportunities for which we do have funding:

Matthieu Bruneaux PostDoctoral Researcher

I did my Ph.D at the Roscoff Marine Station in Brittany studying enzymes from invertebrates inhabiting harsh environments such as intertidal zones or deep-sea hydrothermal vents. I later came to Finland as a post-doc in Prof. Craig Primmer's group at the University of Turku, and got involved in projects focusing on population genetics and molecular evolution in several fish species. I finally moved to Jyväskylä for another post-doc in Dr. Tarmo Ketola's group on the genetic and epigenetic basis of evolution under fluctuating conditions in bacteria, based on strains produced using experimental evolution in the lab.

I will start working in the LoST group in early 2017 and will investigate nutrient cycling in the Trinidadian streams in close collaboration with Andrés and Alexander. My interests are all things evolution (if possible involving some stimulating computational challenges), and after exploring molecular evolution, comparative physiology and population genetics in my previous projects, I will be happy to get my feet wet in evolutionary ecology!

Guillermo Garcia-Costoya

Guille joined our team as an Unergraduate Erasmus Trainee. He investigated the drivers of size-structure evolution in introduced populations of Trinidadian guppies (Poecilia reticulata). He is now back in Barcelona, setting up his new project on the effects of intra- and interspecific competition on the dynamics of endangered Spanish toothcarp (Aphanius iberus), and the invasive mosquitofish (Gambusia holbrooki).

Karendeep Sidhu MSc student

I am currently completing my MSc in Evolution and Ecology, with a specialisation in genetics, at the University of Jyväskylä (Finland). I am interested in the evolution of diversity within and between species, and I first became fascinated by this through my BSc in Anthropology, at the University of Roehampton (England). My masters' thesis allowed me to explore this interest through the use of Neurospora crassa, in order to understand the genetic architecture of phenotypic plasticity. I will be will be joining the LoST team on the Trinidad and Tobago islands to broaden my understanding of the factors that drive diversification in regards to foraging behaviour as part of the team that focuses on the effect that density and frequency have on the foraging behaviour of guppies.‍‍‍

Alex Lee
Alex was a PostDoc with us between 2016 and 2017, working on a variety of issues related to the evolutionary demography of size structured populations, competition, and its ecosystem consequences. He has decided since to leave academia and use his training to help solve problems of affordable housing and healthy organic eating in London.‍‍‍

Hanna Enroth

Hanna did an undrgraduate internship with us to participate on the Spring 2018 field campaign in Trinidad. She participated in density manipulation studies of guppies to study density-dependent dispersal and habitat use.‍‍‍

Sophia Lambert MSc student

I am joining the LoST team for my last year MSc’s internship. I have completed a 2 years MSc in Ecological Engineering at the University of Pierre and Marie Curie (Paris 6, France). I am currently in my second Master Degree working on interdisciplinary approaches in life science at the CRI (Paris, France), specializing on the Eco-Evo approach.It is assumed that evolution can affect ecosystem structures and functions. My work will focus on understanding to what extent evolution can impact ecosystems processes and more precisely nutrient cycling. I will look at how nitrogen goes from the highest trophic level to lower levels in different food web scenarios (high predation pressure to low predation pressure). To answer this question, I will work in situ on Trinidad and Tobago island’s streams using experimental and theoretical approaches (field data and modelling). During this field work, an isotope tracer experiment will help us quantify nitrogen fluxes through ecosystem compartments.
