In the heathlands of the Otways, the high-stakes mating strategy of the threatened Swamp Antechinus (Antechinus minimus maritimus) is becoming an important focus for land managers as they look to undertake more "cool" planned burns in the winter.
Swamp Antechinus mating is tightly synchronised, occurring over just three weeks in winter, after which all males die.
From that moment, the fate of the entire population rests with the surviving females, who must carry and raise their litters through the harshest months until the young become independent. This makes the population incredibly vulnerable over winter, where the death of these ‘single mums’ could spell the end of the population.
Master’s Student Jesse Ellis is working to fill some of the knowledge gaps between this unique biology and winter fire management, to understand how Swamp Antechinus can survive, and thrive, in a landscape managed by fire.
