Marine Ecology Progress Series Evaluation of the Environmental Accounting Methods for the assessment of global environmental impacts of traded goods and services 3.
This tagging procedure typically required less than ten minutes from the moment the shark was caught to the moment it was released. The seasonal pattern of vertical movement observed in our study w1 that in winter, the optimum thermal habitat of grey reef sharks might be restricted to a smaller surface layer of the water column. Unutilizability method for the design of sunspaces.
Introduction Free-ranging marine predators such as sharks live in a three-dimensional environment where they are able to move in both horizontal and vertical planes. To determine movement between these areas, we estimated the minimum linear dispersal minimum dispersal time as the time between the ajalyse detection in the residency area and the time of the first detection in the visiting areaand time spent hours detected in each visiting event.
Furthermore, the largest movement recorded by their study was undertaken by a male shark that travelled km between atolls in the Coral Sea and the GBR. We considered sharks as inter-annual residents when an animal had an annual residency index equal or higher than 0.
Strong site fidelity of juveniles to nursery areas is evident in lemon Negaprion brevirostrisblacktip and Caribbean reef sharks and is thought to be due to the advantages of nurseries in terms of predator avoidance and food availability . There was little variation in the temperature between the northern and southern areas, thus we combined data from both for subsequent analyses.
Journal of The Royal Society Interface 10 A new technique for thermal modelling of building: A better understanding of the ecology of reef sharks in coral reef systems requires the examination of movement and residency patterns on both horizontal and vertical planes. In Aprilwe smix range testing of the receivers in the northern site by deploying a test tag VH, power output dB, frequency of 69 Khz, fixed delay and estimating the detection coefficient at intervals of m along transects parallel and perpendicular to the receiver deployment sites.
Assessing the prospective environmental impacts of photovoltaic systems based on a simplified LCA model.
In contrast, three of five tagged males were never detected or only monitored for short periods of less than 30 days before disappearing from the study area. Due to the autocorrelation inherent in the data, the assumption of temporal independence was violated  ; we addressed this violation by using a matched-block sampling with replacement technique . Our array of receivers operated continuously during the period of study however, due to technical issues, the receivers from the Blue Corner Incoming and Blue Corner Outgoing sites Figure 1 were not operational from April to November and March to Aprilrespectively Figure S1.
We suggest that daily, lunar and seasonal cycles in vertical movement and residency are strategies for optimising both energetic budgets and foraging behaviour. Shark Northern area Southern area Tag no.
While these studies have contributed to our understanding of the habitat preferences of sharks in reef ecosystems, there is an almost complete lack of equivalent data on the movements of reef sharks in the vertical plane of the water column.

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 reflection at the water surface was greatest.

Our results are consistent with those of Field et al. Towards the Eco-design of a tilting train in Korea: Environmental impact for offshore wind farms: The receivers recorded a total of 2.
The limited information that is available suggests that cycles in vertical movement are also a feature of the behaviour of reef sharks. Integrating life cycle costs and environmental impacts of composite rail car-bodies for a Korean train. Our study contributes to a better understanding of the ecology of these animals and has implications for the management of sharks at aggregation sites, an important driver for diving ecotourism and the Palauan economy .

Upper Saddle River, New Jersey: How to assess the Environmental State of EU regions with the global concept of sustainability?. As time series were often interrupted by downloading of receivers, each portion of the interrupted series was considered to be independent and for this reason, the daily attendance index was likely to be a conservative metric of site fidelity at monitored sites. Environmental analysis of enhanced geothermal systems smoa life-cycle assessment and induced seismicity risk criteria.
Many other sharks are known to display vertical movements driven by thermal preferences and this behaviour has been recorded in laminids including shortfin makos and white Carcharodon carcharias sharks.
Two of the tagged sharks were not detected by the array and one individual was detected for only seven days; data for these sharks were not included in analyses. A concurrent increase in 1s rejection coefficient values RC suggests that tag collisions likely contributed to the drop in performance of receivers at this time.
