Spatial and Temporal Dynamics of Contact Zones Between Chromosomal Races of House Mice, Mus musculus domesticus, on Madeira Island.

ABSTRACT: Analysis of contact zones between parapatric chromosomal races can help our understanding of chromosomal divergence and its influence on the speciation process. Monitoring the position and any movement of contact zones can allow particular insights. This study investigates the present (2012-2014) and past (1998-2002) distribution of two parapatric house mouse chromosomal races-PEDC (Estreito da Calheta) and PADC (Achadas da Cruz)-on Madeira Island, aiming to identify changes in the location and width of their contact. We also extended the 1998-2002 sampling area into the range of another chromosomal race-PLDB (Lugar de Baixo). Clinal analysis indicates no major geographic alterations in the distribution and chromosomal characteristics of the PEDC and PADC races but exhibited a significant
