Dear MARMAMers, We currently have what appears to be a relatively isolated population of bottlenose dolphins that has been declining in abundance over the last decade or so. I work for the Department of Conservation in New Zealand and we are trying to identify what the potential causes or contributors to this decline are. One of the unique features of their habitat is the discharge of freshwater into the fiord system that they occupy, and it has been proposed that this may alter the water temperature (at least at certain times of the year) and be causing thermal stress to the dolphins. Therefore, I am interested in gathering information on temperature tolerances and thermoneutrality in dolphins, particularly in bottlenose. The only study that I have been able to find on dolphins is the work of Williams in the early 90's, so any further information would be greatly appreciated. Any information will be used to aid our management decisions and/or guide what additional research needs to be carried out rather than for a specific publication. My contact details are gfunnell@doc.govt.nz Kind Regards, Greig. ############################################## This e-mail (and attachments) is confidential and may be legally privileged. ##############################################
