Genetic assessment of threats to platypus due to river modification

Genetic assessment of threats to platypus due to river modification, PhD thesis

Luis Mijangos   

During my PhD project, I will use genetic analyses to track effects of river regulation on connectivity in populations of platypus (Ornithorhynchus anatinus), which was recently identified as a “near threatened” species, given continuing population declines and threats.

The project will compare genetic estimates between populations upstream and downstream in three pairs of rivers with different levels of artificial fragmentation. We will use a novel combination of genetic methods to quantify recent and historical impacts of river regulation on dispersal rates, population condition, health and dynamics. This information will be used to implement decision analyses that focus effective conservation actions.
