Raquel Monclús is a Marie Curie Fellow at Université Paris-Sud 11 in the laboratory of Ecology, Sysmtes, and evolution. Her research can be divided into two main topics:  the indirect effects of predators and the fitness effects of early life conditions. In particular, she is interested in maternal and sibling effects, and how they modulate an animal´s life-history.

For instance, if animals (or plants) use many resources in producing offspring, they cannot use the same resources to grow or to repair their cells. Therefore, costs might arise. If an
