Research project ANR Aquatherm

Post-doctoral position in Evolutionary Ecophysiology 

The CNRS Ecophysiology lab at CEBC, Chizé, France seeks to recruit a post-doctoral research  fellow in 2018 for a 20 months long period starting in April 2018 (possible extension to 40 months) to examine the functional basis of climate sensitivity in terrestrial ectotherms. The project is part of an ANR-funded research program to improve general understanding of the interactive effects of temperature and water constraints on the ecology of lizards and snakes (squamate reptiles). 

Project description
A  major  challenge  in  ecology  is  to  accurately  predict  responses  of  organisms  to environmental  variation.  In  this  context,  clarifying  proximate  mechanisms  and  possible functional tradeoffs is essential, and integrating physiological mechanisms with ecology and evolution is a relevant and promising approach. Water is vital for terrestrial organisms and this resource exhibits important seasonal and/or spatial fluctuations. Water restriction can alter  individual  performances  and  survival,  and  the  regulation  of  water  balance (hydroregulation)  can  interact  with  other  demands  such  as  energy  and  thermoregulation resulting in physiological and behavioral conflicts. Our group has recently shown that waterbased  functional  trade-offs  can mediate  evolutionary  conflicts  (e.g.,  cost  of  reproduction, parent-offspring conflict), climatic adaptations and  responses to climate change, but these are yet largely unconsidered in evolutionary ecology. The ANR-funded AquaTherm research program precisely focuses on the interplay between hydroregulation and thermoregulation in squamate reptiles (lizards and snakes) with a multidisciplinary approach using mechanistic models, field studies of natural populations, and laboratory studies at the individual level.
The candidate will investigate the functional basis of climate sensitivity in two cold adapted squamate species. He/she will study long-term sensitivity and acclimation responses to joint changes  in  water  availability  and  temperature  focusing  on  the  critical  gestation  and  early growth  (i.e.,  summer  period)  life  stages.  This  work  will  be  based  on  experimental manipulation  of  thermal  and  hydric  conditions  using  climatic  chambers  and  longitudinal measurements  of  associated  metabolic,  water  loss  and  fitness  responses  with  state-of-the art techniques. 

Work environment
The  successful  candidate  will  be  recruited  by  the  CNRS  in  the  CEBC  laboratory  in  Chizé (  in  the  EcoPhysiology  team  and  will  also  be  able  to  closely collaborate with a dynamic group of ecologists and ecophysiologists in France. He/she will be supervised  by  CNRS  Researcher  Olivier  Lourdais,  a  leading  expert  in  thermoregulation, climatic  adaptations  and  reproductive  strategies.  The  student  will  benefit  from  the  local expertise  and  complementary  approaches  to  study  physiological  trade-offs,  behavioral responses and individual performances. Our research program involves the CEREEP-Ecotron IleDeFrance  (Saint-Pierre-lès-Nemours),  iEES  Paris,  CEBC  (Chizé)  and  SETE  Moulis  (Saint Girons) laboratories. The post-doctoral research fellow will thus work in an interdisciplinary and  lively  research  environment  and  will  contribute  to  a  national  collaborative  program involving  more  than  20  researchers  and  staff  including  world  leading  experts  in  animal ecology and ecophysiology. 

Required qualifications and skills
Candidates  should  meet  the  following  requirements  (1)  have  a  PhD  in  ecology, ecophysiology,  or  a  related  field;  (2)  a  background  in  evolutionary  ecology/  organismal biology  /  ecophysiology,  (3)  demonstrated  experience  in  experimental  research,  (4)  a successful publication record and (5) be creative and independent. Candidates are welcome to  come  with  their  own  ideas  provided  they  are  feasible  during  the  time  frame  of  the project.
Terms and salary
The position is available for a period of two years starting preferably in March 2018. Salary is
€22,000  per  year.  Review  of  applications  will  begin  on  December  15,  2018,  and  continue
until the position is filled. The initial appointment is for 20 months with potential renewal for
addition 20 months conditional on additional funding from another grant proposal.
