Ph.D. Candidate
maiyasue@uvic.ca
Supervisor: Dr. Phil Dearden

I completed my BSc in Biology and Geography here at UVic, where I focused on the effects of mangrove afforestation on foraging habitat in Vietnam. From there I went to Oxford, UK to study shorebird predation risk and earn my MSc in Zoology. I have returned to UVic to continue my research on shorebirds and assess their vulnerability to anthropogenic disturbance and habitat loss in Thailand.

As part of the East-Australasian flyway, Thailand’s mudflats, saltpans and aquaculture ponds provide foraging habitats for 61 migratory and 2 resident shorebird species. If managed effectively, Thailand’s 26 marine national parks can help conserve shorebirds during critical life phases by protecting habitats from conversion into resorts, aquaculture ponds or housing developments.

In my two-part study I will assess the possible impacts of human disturbance and habitat loss on the reproductive success of the near threatened Malaysian plover (Charadrius peronii) as well as on a wintering population of grey plover (Pluvialis squatarola), lesser sand-plover (Charadrius mongolus) and redshank (Tringa totanus) at Khao Sam Roi Yod National Park in Prachuap Khiri Khan province.

The aim of the Malaysian plover study will be to assess the degree to which suitable breeding habitats limit Malaysian plover populations by relating the intensity of territorial interactions, the order of occupancy of territories, nest site characteristics to hatch and fledgling success rates. I will determine how Malaysian plovers assess habitat quality (both breeding and chick feeding) and the main causes for nest failure. This information will help park managers designate areas of the park to set aside for the conservation of Malaysian plovers. This is particularly important due to the increase in tourism within the park and the high economic costs of restricting development on beaches. Also, the results from my study may help guide future habitat restoration projects. Furthermore, basic information on the reproductive strategies of these plovers will be necessary to parameterize population viability models for the Malaysian plover.

The goal of winter field season is to examine the possible energetic or predation risk costs of human disturbance, by prey sampling, conducting focal feeding observations, raptor watches and assessing changes in habitat choice throughout the winter. Information on prey densities and intake rates at each habitat can provide the scientific background for zoning of the park to minimize the effect of human disturbance on important feeding habitats. My research will help focus conservation efforts during periods when an alteration in behaviour due to anthropogenic change is most likely to decrease population size.
