THE STEPPE SPECIES OF GASTROINTESTINAL NEMATODES OF SMALL RUMINANTS, WITH A FOCUS ON MARSHALLAGIA: CLIMATE AS A KEY DETERMINANT
International audience We intended to relate the geographic distribution of ruminantgastrointestinal nematodes in relation to steppe climate (andvegetation). Data are either from literature or from newly acquired/available results. Simple or more sophisticated meteorological indiceswere used to char...
