Using State-and-Transition Simulation Models (STSMs) to Explore Dynamic Population Responses to Drought Cycles in Freshwater Ecosystems

Frontiers in Environmental Science, 2022
Climate variability and change pose significant threats to aquatic biodiversity, particularly in areas with low and variable streamflow. Quantifying the magnitude of risk from these threats is made more difficult by the variable responses of individual ...

Fragmentation by major dams and implications for the future viability of platypus populations

Communications Biology, 2022
Major dams are found to disrupt platypus gene flow and dispersal, with higher genetic differentiation found across dams than along similar stretches of undammed rivers, indicating that they act as significant barriers to platypus movement.

Long-term movements and activity patterns of platypus on regulated rivers

Scientific Reports, 2021
The platypus is a semi-aquatic mammal, endemic to freshwater habitats of eastern Australia. There are gaps in the understanding of platypus movement behaviour within river systems, including spatial and temporal organization of individuals.

The history and homology of the os paradoxum or dumb-bell-shaped bone of the platypus Ornithorhynchus anatinus (Mammalia, Monotremata) [PDF]

Vertebrate Zoology, 2022
The os paradoxum or dumb-bell-shaped bone is a paired bone occurring in the middle of the specialized bill of the platypus Ornithorhynchus anatinus. It has been variously considered as a neomorph of the platypus, as the homologue of the paired vomer of ...

Platypus Surfing

, 2020
For this project, we design a self-activated wave enrichment system for a solo male platypus, 'Sam', at Melbourne Zoo. We develop a sensor system that Sam can learn to activate by swimming near the device to trigger a wave sequence, providing both choice

Energy Homeostasis in Monotremes

Frontiers in Neuroscience, 2017
In 1803, the French anatomist Étienne Geoffroy Saint-Hilaire decided that the newly described echidna and platypus should be placed in a separate order, the monotremes, intermediate between reptiles and mammals.

The platypus: an extraordinary animal for teaching [PDF]

, 2017
International audienceIn this paper, we intend to understand how the Platypus (Ornithorhynchus anatinus) is a paradoxical animal both for an epistemologist and for a science education researcher in science education.

Tracing Monotreme Venom Evolution in the Genomics Era

Toxins, 2014
The monotremes (platypuses and echidnas) represent one of only four extant venomous mammalian lineages. Until recently, monotreme venom was poorly understood.
