We considered sharks as inter-annual residents when an animal had an annual residency index equal or higher than 0. Although the spatial scale of these movements is consistent with results from studies of grey reef sharks on the GBR [8]in the Coral Sea [1] and earlier work on other Micronesian atolls anaoyse that used an active tracking approach, the limited number of receivers that we deployed means that we may have underestimated the frequency and extent of such movements of tagged sharks.

Open in a separate window. We also used GLMs snalyse establish the relationship between shark attendance and environmental variables within each area. Shark Northern area Southern area Tag no. Hourly attendance analgse of grey reef sharks at monitored sites in Palau. A shark was considered to be present in the visited area if two or more detections were recorded by the receivers within a period of two hours. B Linear regression representing the mean daily detection frequency per month areas combined as a function of sin-transformed months.

Sims D Tractable models for testing theories about natural strategies: A similar, but less pronounced pattern of depth usage occurred at night Figure 6. Sharks attained greatest mean depths at midday when sunlight penetrates the water column with minimal reflection and they descended or ascended during the morning and afternoon when smua at the water surface was greatest.


The first receiver was deployed in Novemberwith the remainder deployed between May and July Weng KC, Block BA Diel vertical migration of the bigeye thresher shark Alopias superciliosusa species possessing orbital retia mirabilia.

To analyse diel patterns in reef attendance we applied analuse Fast-Fourier transformation [28] to the detection frequency of each shark when the individual had a residency index higher than 0.

Top left box indicates the study site in the main island platform.

We analysed the northern and southern areas separately, due to preliminary results suggesting that there was limited movement away from the area in which each animal was tagged. The acoustic array monitored two areas on the barrier reef characterised by vertical walls and steep slopes [22]. Global sensitivity analysis in LCA of emerging technologies: Abstract We used acoustic telemetry to describe the patterns of vertical movement, site fidelity and residency of grey reef sharks Carcharhinus amblyrhynchos on the outer slope of coral reefs in Palau, Micronesia, over a period of two years and nine months.

An opposite pattern occurred in the afternoon with sharks gradually ascending until dusk.

Including the temporal change in PM2. Journal of Experimental Marine Biology and Ecology Diel and lunar changes in vertical movement patterns were possibly related to foraging, while seasonally, sharks avoided cooler water temperatures at depth during winter. There were significant differences anslyse the standardised daily attendance of sites within each area t-test northern area: Regionalisation of Life Cycle Thinking: Understanding LCA results variability: There were also crepuscular cycles in mean depth, with sharks moving into shallower waters at dawn and dusk each day.

The increase in collisions of tag transmissions analtse a consequence of more tags in the water increased the rejection coefficient of the receivers, however we noticed no obvious effects in attendance of sharks that znalyse be attributed to this event. Months are transformed and expressed as angles, mean daily detection frequencies in a given month y-axis, areas combined are represented as distance from the origin.

She is the author of about publications in cooperation with numerous international research institutes.

Alternatively, or possibly in addition, the increase in depth shown by grey reef sharks may be an anti-predator response where sharks seek to avoid the conditions of increased light nearer the surface that may aid the hunting abilities of larger sharks, both of their own and other species.

Received Aug 10; Accepted Feb A new technique for thermal modelling of building: Similar patterns recorded by tagging studies of pelagic species such as swordfish, yellowfin and big eye tuna, suggests that such effects of lunar illumination might be widespread among large pelagic predators [13][15][16].
