A period of anestrus follows pregnancy or pseudo-pregnancy, there getting just one oestral period of time for the duration of Every single breeding period.

The evolutionary interactions amongst the species have already been studied up to now employing morphological approaches, but extra not long ago, molecular reports have enabled the investigation of phylogenetics relationships. In certain species, genetic divergence is suppressed by the superior amount of gene movement among click over here now distinct populations and exactly where the species have hybridized, significant hybrid zones exist.[8]
