Young wallabies get a free ride
Article Abstract:
The hopping speed of wallabies and kangaroos is increased with little increase in metabolic energy, due to elastic energy savings in the hind limb tendons. It is reported that female tammar wallabies can carry large young with no increase in metabolic energy expenditure, due to this storage capacity. This follows studies of tammar wallabies on a moving treadmill carrying loads equivalent to 15% of their body weight. No significant change in metabolic rate during hopping was caused by adding the load.

Case of the disappearing sports
Article Abstract:
Northern quolls are sexually dimorphic, with the males larger than females and breed only once each year. One of the unique features of this species is that most of the males die within a couple of weeks of mating, which has caused to a decrease in the number of quolls.
