Concerns about the impact of artificial genetic mixing increase as more conservation practitioners consider population augmentation to enhance declining populations of focal species.Byrne and Silla report on an artificial fertilization experiment testing fitness effects of outcrossing in the near threatened brown toadlet.They find strong outbreeding depression in this species, and suggest that experimental cross-breeding precede conservation action to assess potential impacts.Photographs of (a) the brown toadlet (Pseudophryne bibronii), (b) the southern corroboree frog (P.corroboree), (c) the northern corroboree frog (P.pengilleyi), and (d) the red-crowned toadlet (P.australis).Images a, b, and c courtesy of P.G.Byrne, and image d courtesy of D.
