Comparing individual and spatial influences on foraging behaviour in Antarctic fur seals Arctocephalus gazella (2004, background): “…through a number of mechanisms including different prey capture or harvesting tactics (Bence 1986), morphological differences (i.e. age, size, gender; Werner & Gilliam 1984), intra-specific competition (Milinski 1982), experience (Pernal & Currie 2001) and habitat selection (Heithaus et al. 2002).”
Long-term movements of tiger sharks satellite-tagged in Shark Bay, Western Australia (2007, methodology): “…inside the primary Shark Bay study area select habitat patches (1,000 s of m) and microhabitats within patches (100 s of m) that have high prey density, but quickly transit out of the study area (Heithaus et al. 2002, 2006), often returning to the general location at a later date (Heithaus 2001).”
Tiger shark (Galeocerdo cuvier) abundance and growth in a subtropical embayment: evidence from 7 years of standardized fishing effort (2006, background): “Consequently, the tiger shark has the potential to influence marine communities via trophically- and behaviorally-mediated interactions with a variety of prey species (e.g., Lowe et al. 1996; Heithaus 2001; Simpfendorfer et al. 2001; Heithaus et al. 2002; Dill et al. 2003; Heithaus 2004).”
Long-term movement patterns of tiger sharks Galeocerdo cuvier in Hawaii (2009, background): “Short (up to 11 h) acoustic tracks of tiger sharks equipped with video cameras suggest that tiger sharks select habitats where prey are most abundant and utilize stealth as their primary foraging tactic (Heithaus et al. 2002).”
Migratory marine species: their status, threats and conservation management needs (2014, background): “Tracking studies of larger sharks have revealed that individuals often move considerable distances over short periods and may not reuse the same areas until weeks, months or even years later (Holland et al., 1999; Heithaus et al., 2002).”
The ecological importance of intact top-predator populations: a synthesis of 15 years of research in a seagrass ecosystem (2012, background): “…bait-loss rates to teleosts (especially the northwest blowfish, Lagocephalus sceleratus) in shallow habitats were so high that we had to turn to the use of acoustic tracking and animal-borne imaging (Heithaus et al. 2001, 2002a, 2006) to elucidate the habitat use preferences of the tiger shark.”
Does tiger shark predation risk influence foraging habitat use by bottlenose dolphins at multiple spatial scales (2006, background): “Temporal and spatial variation in the abundance of tiger sharks is based on data collected within the study area during the same period as the dolphin study (Heithaus 2001d, Heithaus et al. 2002, in press).”
Sharks in nearshore environments: models, importance, and consequences (2010, background): “Nearshore productivity can also be exploited by sharks that occur in these areas only occasionally, and some species move into nearshore regions from areas further offshore to utilise coastal habitats and feed on high quality prey (Heithaus et al. 2002).”
Novel GPS tracking of sea turtles as a tool for conservation management (2007, background): “For example, correlated random walk models, which randomly draw step lengths from the measured step-length frequency distribution, may provide a more refined test of whether animals are moving randomly (e.g. Heithaus et al., 2002a).”
The role of learning in shark behaviour (2009, background): “The vast information available on shark movement and space utilization (Nelson 1977; Simpfendorfer and Heupel 2004) recognizes that sharks can track both abiotic (Hopkins and Cech 2003) and biotic (Heithaus et al. 2002) changes with some considerable accuracy.”
Action Cameras: Bringing Aquatic and Fisheries Research into View (2015, methodology): “During the 1990s and early 2000s, handheld digital video cameras (both battery powered and tethered) were commonly used in fisheries and aquatic research for assessing habitat (Carleton and Done 1995; Heithaus et al. 2002), estimating fish size (Harvey et al.”
Living on the edge: dugongs prefer to forage in microhabitats that allow escape from rather than avoidance of predators (2007, methodology): “We selected these microhabitat designations because (1) they are each well represented and (2) we assumed that dugongs occupying them are differentially able to manoeuvre and escape to deep (refuge) patches while under attack from tiger sharks (Heithaus et al. 2002, 2006).”
Pelagic habitat characterization of loggerhead sea turtles, Caretta caretta, in the North Pacific Ocean (1997–2006): Insights from satellite tag tracking and remotely sensed data (2008, methodology): “The track randomization approach of Heithaus et al. (2002, 2006) offers much promise towards characterization of microhabitat using tracking information.”
BEHAVIORALLY MEDIATED INDIRECT INTERACTIONS IN MARINE COMMUNITIES AND THEIR CONSERVATION IMPLICATIONS (2003, background): “This concentration of prey in summer attracts many tiger sharks (Galeocerdo cuvier), which concentrate their foraging in the shallow seagrass habitats preferred by their prey (Heithaus et al. 2002).”
Tractable models for testing theories about natural strategies: foraging behaviour and habitat selection of free‐ranging sharks (2003, background): “One, or a combination of factors may be important in determining spatial distribution and this will vary between species (Heithaus et al., 2002).”
