Temporal pattern of sampling of kin from the groups of short-beaked common dolphins (Delphinus delphis) along the Portuguese coast

The table shows the number of different kin groups that included individuals sampled within the same time classes (the same day, month or year). ‘Whole group’ refers to groups where all the individuals were sampled in the specific time class, whilst ‘containing individuals’ refers to groups where only some individuals were found in the specific time class. Note that grouping in time classes is hierarchical; e.g. the number of individuals sampled in the same month also includes individuals sampled in the same day
