Figure 2From: Non-invasive assessment of the reproductive cycle in free-ranging female African elephants (Loxodonta africana) treated with a gonadotropin-releasing hormone (GnRH) vaccine for inducing anoestrusScatter plot of faecal progesterone metabolite concentrations from 12 female African elephants during one-year study. Circles represent individuals from the Lower Escarpment herd (n = 8) and triangles represent individuals from the Upper Escarpment herd (n = 4). Line represents overall mean monthly FPM concentration. Vertical bars represent mean monthly rainfall corresponding to the study period for the Lower Escarpment (dark grey bars) and Upper Escarpment (light grey bars).Back to article page
