Frontiers of Research in Industrial Ecology, Workshop 6: We also found significant differences in the mean daily detection frequencies per month for all sharks Table 3indicating that although sharks visited the monitored areas regularly through the year, there was a degree of seasonality, with a higher detection frequencies recorded mainly during summer June to September and lower detection frequencies in winter and spring January to April Figure 4.

More individuals were detected during the day than at night. The seasonal pattern of vertical movement observed in our study suggests that in winter, the optimum thermal habitat of grey reef sharks might be restricted to a smaller surface layer of the water column.

Ten of these tags were also fitted with pressure sensors that recorded depths to a maximum of m five VH, deployed inm two VH deployed in or m three VH deployed in Figure S2 Metrics of receiver performance during grey reef shark acoustic monitoring period in Palau. Unutilizabilty Method for the Design of Sunspaces.

We used acoustic receivers VR2w, Vemco to monitor the attendance of tagged sharks at five aggregation sites. However, there was some degree of variation in site fidelity of several mature females, which is supported by the observation of movements between the northern and southern areas a distance of We used ANOVA and a t-test [27] to compare site preferences in the southern and northern areas respectively.

Fisheries data for a range of other pelagic sharks and tunas also support this idea, although some species such as the black marlin Makaira indica show the opposite pattern, with catches increasing in shallow waters during the full moon [52].

A parameterized model for Denmark. Diel patterns of corrected detection frequencies are represented as peaks of relative magnitude of spectral component. Including the temporal change in PM2. Our study snia was the edge of the main qnalyse platform that consists of a large shallow-water lagoon arrayed with small, uplifted limestone islands and a large volcanic island, all of which are enclosed by a km barrier reef [22].

At night, the mean depth inhabited by grey reef sharks increased through the lunar cycle, so that the greatest depths coincided with the full moon.

Understanding LCA results variability: Similarly, there is evidence that whale sharks Rhincodon typus spend long periods warming up their bodies in the surface after long deep divers in cold waters [49]. Environmental Impact Assessment ReviewElsevier,52, pp. Our results confirm previous suggestions that grey reef sharks display strong levels of site fidelity that persist across years, at least for some components of the population. This project was funded by the Save Our Seas Foundation http: We also estimated the mean number of hours detected per day when a shark attended a given site.

This cyclical pattern of descent and ascent was less pronounced at night. Once caught, sharks were brought alongside the boat and restrained within a canvas stretcher, which was then lifted onboard.

Towards a global criteria based framework for the sustainability assessment of bioethanol supply chains: Analyse du cycle de vie: Meeuwig2 and Conrad W. In coral reef ecosystems, most studies of the movement of sharks have focused on defining patterns of use of space on a horizontal plane, many with the ultimate goal of contributing to spatial management strategies, such as marine protected areas, to ensure the adequate conservation of shark populations.

Mean number of sharks detected in each hourly bin throughout the study period.

Given that greater activity patterns of grey reef sharks during twilight and night hours are thought to be related to foraging behaviour s,ia[5][42]it seems likely that the use of deeper waters during the full moon could be a response to equivalent changes in distribution patterns of their sima. Received Aug 10; Accepted Feb Discussion Site fidelity and horizontal movement Grey reef sharks in Palau displayed high levels of inter-annual residency, with tagged sharks detected at the same sites along the outer reef slopes for over two years.

Environmental relevance of composite materials for trains through LCA.

Renewable EnergyElsevier,50, pp. We would also like to thank Cyprien Bosserelle and Yuval Berger for support with the analysis. Swiss bioethanol supply inWhat are the sustainability stakes of two scenarios for Switzerland?. For example, the nocturnal patterns of vertical migration of school sharks are depressed during the nights of full moon [44]while juvenile white sharks descend to greater depths with higher frequency during the nights of full moon [48].

National Geographic Society Research Reports A new technique for thermal modelling of building: Standardised mean daily attendance of grey reef sharks in the monitored areas in Palau. Range testing indicated that there was an overall decrease in the detection coefficient within a m radius of the receivers. Our tagged sharks displayed high levels of site fidelity and residency throughout the year, implying that our results are robust despite the limited number of receivers in our array.

We considered sharks as inter-annual residents when an animal had an annual residency index equal or higher than 0. We suggest that daily, lunar and seasonal cycles in vertical movement and residency are strategies for optimising both energetic budgets and foraging behaviour.
