Acknowledgements,
We are particularly indebted to all the people in Senegal who welcomed us into their homes for small mammal trapping. We also thank all those who have helped us locally to make these surveys possible, from village chiefs to local contractors. Fundings came from the CHANCIRA (Contract ”ANR‐11‐CEPL‐010”), and ENEMI (Contract ”ANR‐11‐JSV7‐0006” projects. Additional fundings and logistical support came from Research Unit CBGP (”Centre de Biologie pour la Gestion des Populations”).
