Dhole Ecology and Conservation
Research output: Book/Report › Ph.D. thesis › Research
Dholes also known as Asiatic wild dogs are large, social carnivores considered endangered by the IUCN. Globally threated by habitat loss, prey depletion, human persecution due to livestock predation and potentially diseases transferred by domestic dogs. In this PhD thesis I focused on the ecology and conservation of dholes particularly in Baluran National Park, East Java Indonesia.
Chapter I is a review paper providing an updated status and distribution of dholes in Indonesia based on published data from camera traps and anecdotal presence records. We found that dholes were mainly present in protected areas however, not many camera trap studies from Indonesia focused on dholes and the presence or absence of dholes was not always presented. We therefore urged researchers to publish data with dhole presence records in order to get a better understanding of their distribution and status in Indonesia.
In chapter II we estimated the population size of dholes in the Western Ghats in
India using three novel methods for population estimates of unmarked populations. The Space-to-Event model proved to be the best performing model corresponding to population estimates based on field observations and best match of leopard estimates based on Spatially Explicit Capture-Recapture (SECR) models. The Space-to-Event model can be used to
estimate the population size of dholes and other species of interest that lack individually recognisable markings allowing for continues monitoring of predator and prey populations.
In chapter III we studied the activity patterns of dholes, their putative prey and competitor in Baluran National Park. We found that dholes in Baluran National Park are primarily crepuscular with a high degree of overlap between dholes and wild ungulates.
Dholes and leopards have significantly different activity patterns which suggests temporal partitioning, whereas dholes and humans have a moderate temporal overlap especially in the morning hours. Dholes roaming alone or in pairs were found to have a significantly different
