Subject: Second International Conference on Acoustic Communication by
Animals
This conference will help researchers share ideas, data, and methods in
the growing and exciting field of animal acoustic communication. The aim
will be to bring together senior scholars, mid-career researchers and
teachers, young investigators, and students to share information and ideas
across animal taxa. The conference is Aug. 12-15, 2008, with an abstract
deadline of April 18.

Subject: Post-doc.Paris.1year.Populationmodelling
Physiologically structured population models for viability analysis
One Post-doctoral position 2008-2009 available at the Ecology-Evolution
Laboratory (CNRS, UMR 7625) at the Ecole Normale Supérieure (CERES-ERTI)
in Paris.
Applications are invited for a one-year postdoctoral position funded by
R2DS (http://www.r2ds.centre-cired.fr/) to investigate the dynamics of
small populations with plastic life histories using physiologically
structured populations models.
Population persistence is notably conditioned by the degree of individual
variation in reproductive success, which depends on variation in any part
of the life cycle. Yet, the majority of studies that examined population
extinction have tended to ignore life history variation and plasticity.
Here, we wish to use life history models to inform the dynamics of small
populations and ask how plasticity in life history traits influences
extinction dynamics. Many aspects of life history can interact with
population dynamics and the project concentrates on three of them, namely
growth, maturation and survival.
The post-doc will explore this issue by developing models that account for
variation in life history traits using the theory of physiologically
structured populations (PSP). This theory takes into account that
physiological development (e.g. growth, maturation) depends on the current
state of the environment (e.g., temperature, food and predator densities).
In turn, the influence of the population on the environment closes a
feedback loop between environment, population and life history. The theory
of PSP models is thus particularly well-suited to study the interaction
between population dynamics and plastic life history. Small populations
are subject to stochastic fluctuation in abundance. The project aims to
study the feedback of this variability on life history and the
consequences for extinction dynamics. The models will be parameterized
with estimates from field and experimental studies undertaken with the
common lizard, a species with strong thermal and food plasticity in life
history traits.
The post-doc will be based at the Ecology-Evolution Laboratory (CNRS, UMR
7625) at the Ecole Normale Supérieure (CERES-ERTI) in Paris, where the
applicant will work with David Claessen and Jean-François Le Galliard.
This post-doc project is part of a research network on the dynamics of
small populations funded by ANR from 2008 to 2012 and will therefore
interact with a larger group of researchers. The post can start on
September 1st or October 1st 2008 and will run for one year with a
possible one year extension by applying to extended funding from the R2DS
network in spring 2009. Gross salary will be 2500€ per month. The starting
date can be postponed in exceptional circumstances.

at least one year.
(3) Have strong competence in modeling, with an interest in population
dynamics, viability analyses and conservation biology and knowledge of C
programming or closely related languages.
