Predator interactions, mesopredator release and biodiversity conservation. (2009, background): “Both predation risk and prey availability influence dolphin habitat use, but intrinsic risk associated with habitat type rather than simple encounter rates with predators is critical in influencing dolphin foraging (Heithaus & Dill 2006).”
Apparent Resource Partitioning and Trophic Structure of Large-Bodied Marine Predators in a Relatively Pristine Seagrass Ecosystem (2013, background): “Second, many individual dolphins largely abandon seagrass habitats during the 9 mo of the year that tiger sharks are abundant (Heithaus & Dill 2002, 2006), while others forage almost exclusively in channel habitats throughout the year (Mann & Sargeant 2003), where seagrass cover is sparse…”
Living on the edge: dugongs prefer to forage in microhabitats that allow escape from rather than avoidance of predators (2007, background): “Bottlenose dolphins (Tursiops sp.) in our study area also select foraging microhabitats within seagrass meadows that facilitate escape to deep habitat, rather than those with the lowest predator density, during periods of heightened danger from tiger sharks (Heithaus & Dill 2006).”
Spatial responses to predators vary with prey escape mode (2010, background): “…escape predators by fleeing into and outmanoeuvring their attackers in deeper water, shift to the edge of sea grass banks where shark abundance is relatively high (Heithaus et al. 2006), but escape probability is greater due to access to deeper waters (Heithaus & Dill 2006; Wirsing et al. 2007).”
Effects of predation risk on group size, vigilance, and foraging behavior in an African ungulate community (2014, background): “measure their costs, and understand relationships between direct predation and risk effects in the wild (Heithaus and Dill 2006; Creel and Christianson 2008; Schmitz 2008; Creel 2011).”
Behavioural drivers of the ecological roles and importance of marine mammals (2015, background): “…267–281, 2015 viduals that continue to forage in shallow habitats during periods of high risk avoid foraging over the interior of seagrass meadows (ca. 80% of the total seagrass area) relative to safer bank edges (Heithaus & Dill 2006, Wirsing et al. 2007a, see Heithaus et al. 2012 for a review).”
Habitat use and movements of plains zebra (Equus burchelli) in response to predation danger from lions (2007, background): “Prey species’ responses to predation threat shape many ecological processes: population distribution (Lima and Dill 1990; Heithaus and Dill 2006), resource exploitation by prey (Fortin et al. 2005), and vital rates (Bleich 1999).”
Effects of body size, age and maturity stage on diet in a large shark: ecological and applied implications (2008, background): “…have substantial impacts on marine communities through the control they exert on mesoconsumers such as smaller sharks, rays, marine mammals, seabirds and turtles (Lucas and Stobo 2000; Acevedo-Gutiérrez 2002; Heithaus and Dill 2002, 2006; Heithaus 2005; Heithaus et al. 2007; Wirsing et al. 2007).”
Seascapes of fear: evaluating sublethal predator effects experienced and generated by marine mammals (2008, background): “…of time allocation by foraging prey, an approach that has yielded tremendous insight regarding the ecology of terrestrial mammals, and (2) illustrate its utility in marine environments with examples from our work in two systems—Shark Bay, Western Australia, and Prince William Sound, Alaska.”
Hunting patterns and geographic profiling of white shark predation (2009, background): “…concentrate their movements to maximize encounter rates with prey [e.g. tiger sharks Galeocerdo cuvier (Péron & Lesueur), Heithaus et al., 2002; Heithaus & Dill, 2006; white sharks Carcharodon carcharias (Linnaeus), Klimley et al., 1992, 2001a,b; Goldman & Anderson, 1999], sample sizes were…”
Can environmental heterogeneity explain individual foraging variation in wild bottlenose dolphins (Tursiops sp.)? (2007, unknown): “Shallow and deep transects were paired and alternated between deep and shallow areas across the study area, which decreases the likelihood of spatial autocorrelation (see Heithaus and Dill 2006).”
Long-term movements of tiger sharks satellite-tagged in Shark Bay, Western Australia (2007, background): “At smaller spatial scales, dolphins and dugongs reduce their use of the more dangerous interior portions of shallow banks relative to edge microhabitats to reduce their probability of being captured by tiger sharks (Heithaus et al. 2006; Heithaus and Dill 2006; Wirsing et al. 2007).”
Long-term movement patterns and trophic ecology of blacktip reef sharks (Carcharhinus melanopterus) at Palmyra Atoll (2010, background): “…apex predators is particularly important as the relationship between home range size, habitat selection, and trophic ecology can lead to spatially explicit differences in top down control and other cascading processes (e.g. Dill et al., 2003; Whitehead and Rendell, 2004; Heithaus and Dill, 2006).”
