Social structure of the mound-building mouse Mus spicilegus revealed by genetic analysis with microsatellites.

The Mound-building mouse Mus spicilegus possesses a unique behaviour amongst mice. It constructs large earthen mounds and associated nesting chambers which serve to store food for immature individuals during the winter nesting period. We have used genetic analysis of four autosomal and four X-linked microsatellite loci to determine relationships between individuals inhabiting 40 mounds in Bulgaria.

Genic differentiation and origin of Robertsonian populations of the house mouse (Mus musculus domesticus Rutty).

This paper examines the relation between chromosomal and nuclear-gene divergence in 28 wild populations of the house mouse semi-species, Mus musculus domesticus, in Western Europe and North Africa. Besides describing the karyotypes of 15 of these populations and comparing them to those of 13 populations for which such information was already known, it reports the results of an electrophoretic survey of proteins encoded by 34 nuclear loci in all 28 populations. Karyotypic variation in this taxon involves only centric (or Robertsonian) fusions which often differ in arm combination and number between chromosomal races.

[The phlebotomines of Tunisia (Diptera-Phlebotominae). A revision of the systematics, distribution and behaviour (author's transl)].

The authors present a revision of the systematics, distribution and ethology of the phlebotomine sandflies of Tunisia. They present a dichotomous key for 15 taxa. A biogeographical analysis shows the connexion between foci of visceral leishmaniasis and the zones of distribution of the subgenus Larroussius.

[Ecology of leishmaniasis in southern France. 9. Sampling methods in the study and analysis of canine enzootic leishmaniasis].

An account is given of the fundamental methods used on an investigation of the canine enzootic of leshmaniasis in the Cévennes. The objective was to determine the relationship between the prevalence of infection on dogs and the density of the sandfly vector. The basis of the work was a phyto-ecological map of the two parameters.
