Ontogenetic dietary shifts and feeding behavior of the tiger shark, Galeocerdo cuvier, in Hawaiian waters
Comparisons between the diets of tiger sharks from Hawaii and other locations indicate that ontogenetic shifts are universal in this species and that tiger sharks may be opportunistic feeders that prey heavily on abundant, easy to capture prey. Expand
Scale-dependent effects of habitat on movements and path structure of reef sharks at a predator-dominated atoll.
Microhabitat quantity and quality had large effects on blacktip reef shark movements, which have consequences for the life-history characteristics of the species and potentially the spatial distribution of behaviorally mediated effects on lower trophic levels throughout the Palmyra ecosystem. Expand
Movements of tiger sharks (Galeocerdo cuvier) in coastal Hawaiian waters
The data suggest that Hawaiian tiger sharks move within large home ranges and that they can efficiently navigate between distant parts of their range, even when this requires crossing open ocean waters. Expand
The effects of barotrauma on the catch-and-release survival of southern California nearshore and shelf rockfish (Scorpaenidae, Sebastes spp.)
Two experiments were used to assess the effects of barotrauma on initial capture survival and short-term postrecompression survival of line-caught (range 18–225 m) southern California rockfish (Seb...
Diel movement patterns of ocean sunfish Mola mola off southern California
Ocean sunfish Mola mola are a seasonally common inhabitant of southern Californian waters, and comprise the largest bycatch component (29% of total catch) of the California drift gill- net fishery… Expand
Distribution, reproduction and diet of the gray reef shark Carcharhinus amblyrhynchos in Hawaii
These sharks have a restricted distribution in the MHI; they were collected only in the vicinity of Niihau and Molokini islands, but were one of the most abundant sharks throughout the NWHl. Expand
Testing a new acoustic telemetry technique to quantify long-term, fine-scale movements of aquatic animals
The VPS provides a more efficient, less expensive approach to study and quantify fine-scale, long-term movements and habitat use of multiple individuals simultaneously, with the potential for improving the understanding on ecological and behavioral population level processes in aquatic environments. Expand
Movements, behavior and habitat preferences of juvenile white sharks Carcharodon carcharias in the eastern Pacific
It is demonstrated that the nursery region of white sharks includes waters of southern California, USA, and Baja Cali- fornia, Mexico, and juvenile white sharks captured as bycatch in both US and Mexican waters, suggesting that management of fishing mortality should be of increased concern. Expand
Metabolic rates of juvenile scalloped hammerhead sharks (Sphyrna lewini)
- C. Lowe
- 1 September 2001
Tailbeat frequency and swimming speed can be used as predictors of metabolic rate of free-swimming juvenile hammerhead sharks, indicating that they are most energy efficient at swimming speeds between 0.75 and 0.9 L s–1. Expand
Distribution and diet of four species of carcharhinid shark in the Hawaiian Islands: evidence for resource partitioning and competitive exclusion
The hypothesis that interspecific competition influences the distribution of carcharhinid sharks throughout the Hawaiian Archipelago is supported. Expand
