Projects

Conservation physiology may be defined as the application of physiological theory, approaches and tools to elucidate and address conservation problems with the aim to provide a mechanistic understanding of how environmental disturbances and threatening processes impact physiological responses and thereby ecological function, population persistence, and species survival.” Seebacher & Franklin 2012

My research topics encompass different concepts such as eco-physiology, evolutionary biology, population dynamics, immuno-ecology, reproductive biology and behavioural ecology. My multidisciplinary research allows me to respond to various issues raised in the physiology of conservation.

Effects of climate change on the population dynamics of alpine marmots (Marmota marmota)

Understanding and predicting the impact of climate change on biodiversity is a real scientific challenge and a major economic as well as societal one. The scientific objective of our project is to develop an integrated and mechanistic approach to understanding the causes and consequences of climate change surrounding the alpine marmot. This project is innovative and unique because it is one of the first studies to combine physiological, demographic and evolutionary mechanisms and integrate them into a mathematical model to predict the state of alpine ecosystems in 20-30 years’ time, and so guide the current management methods to achieve desirable objectives.

Phenotypic flexibility and energy compromises in a heterothermic primate (Microcebus murinus)

Could heterothermic organisms compensate for new environmental constraints imposed by climate change by adjusting their energy balance? In other words, is the expression of torpor adjusted in response to a decrease in food availability? Does the adjustment of torpor allow them to counterbalance the energy demands imposed by an immune response or the energy costs of reproduction? Does phenotypic plasticity allow them to maintain a constant selective value despite decreases in food availability?

Longitudinal studies of vertebrates suggest that responses to global change are largely due to phenotypic plasticity. But the mechanisms of plasticity are rarely identified and studied, which limits our ability to predict the potential resilience of organisms to global change.

My research has sought to assess the capacity of heterothermic organisms, especially Microcebus murinus (the mouse lemur), to compensate for various levels of energy constraints, as well as the limitations and costs associated with physiological flexibility.

We have been able to demonstrate that the adjustment of energy expenditure, via modulation of expression of torpor in response to the energy constraints of the environment, can form a pre-adaptation to climate change, giving heterothermic organisms a mechanism for resilience to climate change.
