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.

Differential movement patterns and site fidelity among trophic groups of reef fishes in a Hawaiian marine protected area
Results indicate relatively small MPAs (<2 km of coastline) could provide effective, long-term protection for multi-species assemblages of reef fishes provided that boundaries are situated along major habitat breaks that may serve as natural barriers to reef fish movements. 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
Spatial memory and animal movement.
This work draws together research from several disciplines to understand the relationship between animal memory and movement processes, and frames the problem in terms of the characteristics, costs and benefits of memory as outlined in psychology and neuroscience. Expand
Long-term movement patterns and trophic ecology of blacktip reef sharks (Carcharhinus melanopterus) at Palmyra Atoll
Animal movements, residence times, and subsequently foraging strategies, should vary with habitat quality, and there was no relationship between total length (TL) and δ 15 N, 13 C relative isotope concentrations, or a Body Condition index (BC) for sharks in the western lagoon. Expand
Movement patterns, home range, and habitat utilization of adult kelp bass Paralabrax clathratus in a temperate no-take marine reserve
The small home ranges and high site fidelity of kelp bass in this reserve indicate that the reserve is effective in protecting the resident adult stock. Expand
Telemetry and random-walk models reveal complex patterns of partial migration in a large marine predator.
Animals are often faced with complex movement decisions, particularly those that involve long-distance dispersal. Partial migrations, ubiquitous among all groups of vertebrates, are a form ofExpand
Mesophotic coral ecosystems are threatened and ecologically distinct from shallow water reefs
Evidence is presented contradicting two assumptions that there is considerable overlap in species composition and connectivity between shallow and deep populations and that deep reefs are less susceptible to anthropogenic and natural impacts than their shallower counterparts that are argued to be contradicted.

Seasonal and diel movements of giant trevally Caranx ignobilis at remote Hawaiian atolls : implications for the design of Marine protected areas
We need to understand the long-term movement patterns of coral reef top predators in order to design marine protected areas that will provide these animals with effective, long-term pro- tection. WeExpand
Long-term movement patterns of tiger sharks Galeocerdo cuvier in Hawaii
A network of acoustic receivers was used to quantify the long-term movements of transmitter- equipped tiger sharks in the Main Hawaiian Islands, finding that juvenile tiger sharks were significantly wider-ranging and less frequently detected than mature females. Expand
