The larvae-toting parental care of many species of the Family Dendrobatidae is known to be an effective way to ensure tadpoles have food and protection while they develop. A study by PaĊĦukonis, Loretto and Rojas (2019) asked further about the role of this parental shuttling in dispersal. With tiny radio transmitters, they tracked two poison frog species (Ameerega trivittata and Dendrobates tinctorius) and found that they moved their offsprings farther and to many more water sources than expected, with little regard to suitable, nearby pools. Examining the spatial patterns of the far-ranging fathers, the authors speculate on the adaptive benefits of ensuring the dispersal of their offspring to reduce competition and possible inbreeding against the increased costs and risks associated with long-distance travel. Their study highlights the parental role in offspring dispersal and the spatial acuity of these poison frogs.
