The symposium aims to be a regular retreat for PhD students in any ecological discipline. The symposium provides a great opportunity for students carrying out their thesis in a Catalan research centre to share and receive valuable feedback, on both their ecological work and presentation skills. The symposium will also be a space to network and socialize with other students and seniors.

A panel of three prominent ecologists will evaluate oral presentations in a relaxed and constructive atmosphere. These researchers will also give a plenary talk during the symposium. We are happy to announce Hanna Kokko (University of Zurich), Fernando Valladares (MNCN-CSIC, Madrid) and Rohan Arthur (Nature Conservation Foundation, India) as the evaluators and keynote speakers for this first edition.

A scientific committee will select a maximum of 12 oral presentations. The first best presentation will be awarded with the registration fee for attending an international ecological meeting to be held during 2020 in Europe (up to 400€). The second and third best presentations will also be awarded with vouchers for ecological books (up to 150€ each). Registration is free. All students and seniors should register to attend the symposium. CEAB will offer catering during coffee breaks and lunch, so it is important to know the number of attendants for optimal logistics.

Important dates

  • 20 May:           Start of abstract submission/ Start of registration
  • 15 July:           Deadline for abstract submission
  • 30 July:           Deadline for registration/ Notification of presentation selection
  • 3-4 October:   The ΣPhD symposium

 

Details of the symposium

Registration

Please send your name, position and affiliation to theephd@ceab.csic.es, as well as your intention to give an oral presentation (see below). Confirm also whether you will attend the first day of the meeting, when lunch will be offered to all attendants. Remember that deadline for registration is July 30th. If you register and later on you have some reason not to attend, please let us know.

Abstract submissions

Only students that have not yet submitted their PhD thesis can participate. Please send your abstract to theephd@ceab.csic.es (preferable pdf files). Do not forget to include a title, your name and affiliation and a summary of no more than 350 words. Please also include in which year your PhD thesis is actually running. Remember that deadline for abstract submission is July 15th. The scientific committee will select 12 abstracts for presentations.

Oral presentations

Presentations will last 15 minutes + 10 minutes for questions from the evaluators. We ask you to stick on time because timing will be a criterion to evaluate your presentation! Other criteria will be:

  • Organization of the talk and aim of the study
  • Scientific contents, particularly conceptual background and conclusions
  • Voice and body language
  • Visual aids, especially large readable and brief text, clear graphs, good balance between text and images.

In addition to questions, evaluators will fill a simple file with a qualification and some advice for improving your presentations. Keep in mind that the symposium (oral presentations, questions and plenary talks) will run in English.

Venue

The symposium will take place in Blanes. Details about how to get CEAB are at: http://www.ceab.csic.es/en/

Accommodation

Blanes has many hotels at different prices; however for those with a lower budget and to encourage student’s interactions, the CEAB also offers free accommodation at some researcher’s and students homes. Those interested, write an email to theephd@ceab.csic.es.

Scientific committee

Plenary Talks

Two stories about modellers’ intuition, senescence, and sex

Mathematical modelling always comes with assumptions that are unlikely to met in nature – yet most of us would agree models can be useful. But what if two sets of modellers reach opposite conclusions? This is a situation with the question of whether lower extrinsic mortality selects for delayed senescence: some argue it is valid to say it does so, others claim such logic is flawed. I will try to clarify the situation especially with respect to density dependence. Thereafter, I will turn to empirical (statistical) modelling of another question: how should one measure the opportunity costs of paternal care — crucial in models but rarely estimated? The example — black coucals breeding in Tanzania — utilizes an information-theoretic approach to data analysis, and I will explain why I like this approach.

We do not understand the individual responses to climate change (and what the hell are we waiting for?)

Divergence in phenotypic plasticity among species and populations is considered crucial for adaptation to global environmental change. But there is not a general pattern among either experimental or theoretical studies. Plasticity acting at the level of the individual is considered a rapid mechanism for surviving under rapidly changing conditions. But plasticity can also retard adaptation by shifting the distribution of phenotypes in the population, shielding it from natural selection. We know that not all plastic responses are adaptive and there are evolutionary intriguing ecological traps. Plasticity may buy time for populations, but whether it will be enough, given the rate of environmental change, is unknown. There are emerging modelling approaches attempting to explain future changes in species distribution ranges based on phenotypic plasticity and local adaptation of fitness‐related traits measured across geographical gradients. Predictions generally deliver a less alarming message than previous modelling exercises, suggesting that phenotypic plasticity could help some populations to persist under climate change. But, again, this is hampered by our fragmentary understanding of the ecological meaning of plasticity.

Balance as metaphor in ecology and practice

Nature is inherently balanced. Our role as natural scientists is to identify the fundamental forces that hold this balance together. Humans are disrupting this delicate balance. Our role as conservation thinkers and practitioners is to locate the ruptures and restore the fabric of nature before it shreds completely. There are few ideas as comforting and as powerful as balance in nature. Something feels right about it. It seems to pass a psychic if not entirely rational Ockham’s razor. It forms the epistemic fabric of much of ecological science and is the basis of much contemporary conservation philosophy. Sure, there have been many attempts to challenge these assumptions based on observation, theory and practice, but it has proven remarkably resilient to these anarchic movements. From the perspective of a half-hearted conservation practitioner working in India, I will discuss the power and tyranny of this metaphor when thinking about the natural world and attempting to manage it.
