Laser photogrammetry improves size and demographic estimates for whale sharks
Whale sharks Rhincodon typus are globally threatened, but a lack of biological and demographic information hampers an accurate assessment of their vulnerability to further decline or capacity to recover. We used laser photogrammetry at two aggregation sites to obtain more accurate size estimates of free-swimming whale sharks compared to visual estimates, allowing improved estimates of biologica...
متن کاملAcoustic telemetry reveals cryptic residency of whale sharks.
Although whale sharks (Rhincodon typus) have been documented to move thousands of kilometres, they are most frequently observed at a few predictable seasonal aggregation sites. The absence of sharks at the surface during visual surveys has led to the assumption that sharks disperse to places unknown during the long 'off-seasons' at most of these locations. Here we compare 2 years of R. typus vi...
متن کاملFeeding Behavior in Three Species of Sharks
THIS REPORT concerns a study of the feeding behavior in three species of sharks: Carcharhinus menisorrah Miiller and Henle, the grey shark (Fig. 1), Carcharhinus melanopterus Quoyand Gaimard, the blacktip shark (Fig. 2), both of the family Carcharhinidae; and Triaenodon obesus Riippell, the whitetip shark (Fig. 3), of the family Triakidae. The study was conducted in the lagoon at Eniwetok Atoll...
متن کاملSymbiotic Relationships in Internet Routing Overlays
We propose to construct routing overlay networks using the following principle: that overlay edges should be based on mutual advantage between pairs of hosts. Upon this principle, we design, implement, and evaluate PeerWise, a latency-reducing overlay network. To show the feasibility of PeerWise, we must show first that mutual advantage exists in the Internet: perhaps contrary to expectation, t...
متن کاملTrends in sightings and environmental influences on a coastal aggregation of manta rays and whale sharks
Sightings of planktivorous elasmobranchs at their coastal aggregation sites are often linked to biological, environmental and temporal variables. Many large planktivorous elasmobranchs are also globally threatened species, so it is necessary to try and separate population trends from environmentally driven, short-term fluctuations. We investigated the influence of environmental variables on sig...
