  abstract = {{T}o evaluate the impact of climatic change on rodent sahelian communities, we analysed the contents of over 2500 barn owl ({T}yto alba) pellets collected along the {S}enegal river between 1989 and 2003, and from the {F}erlo sahelian area in 2003. {T}hese results are compared with data from the 1970s and 1980s in the same zones. {R}odents were the most common prey (over 90%). {G}erbillinae were most common in dry areas (84 to 96%) whereas in wetlands and rice fields murines were most common (77 to 88%). {N}owadays, the genus {G}erbillus constitutes the main prey in dry areas (77% to 88%). {T}he genus {T}aterillus, which was the most abundant rodent in the {F}erlo in the 1970s, now represents only 7% of rodents. {G}erbils were not present in {S}enegal before the 1980s: {G}. tarabuli and {G}. henleyi were trapped for the first time in 1989 at the northern border of {S}enegal, and {G}. nigeriae 10 years later at the same place. {T}he latter is now present a hundred kilometres southwards and as abundant in owl pellets as the two other gerbils.},
