Status of dugongs in waters around Palau Status of dugongs in waters around Palau

The dugong, Dugong dugon, is widely distributed throughout the Indo-Pacific region in shallow tropical and subtropical waters (Nishiwaki and Marsh 1985).The International Union for Conservation of Nature and Natural Resources lists the species as vulnerable (Thornback and Jenkins 1982), as it is severely depleted or extinct in many parts of its former range (Nishiwaki and Marsh 1985)...

A double survey estimate for sighting probability of sea otters in California A double survey estimate for sighting probability of sea otters in California

We developed an estimator for the probability of sighting sea otters (Enhydra lutris) by shore- based counters, based on simultaneous double-surveys. We then estimated probability of sighting sea otters in California and evaluated the estimator's principal assumptions. The overall probability of sighting sea otters on 5 replicated double-surveys at each of 6 study areas was 0.945...
