Don't bite the hand that feeds: assessing ecological impacts of provisioning ecotourism on an apex marine predator (2012, background): “…have revealed that changes in tiger sharks functional ecology can induce behavioural changes in prey that may influence community dynamics (Heithaus et al. 2008); and finally, they are listed as 'near threatened' by the International Union for Conservation of Nature (IUCN) (Simpfendorfer…”
A comparison of shark and wolf research reveals similar behavioral responses by prey (2011, background): “2008), but our understanding of the factors governing their strength and nature in particular cases remains incomplete (Creel and Christianson 2008; Heithaus et al. 2008).”
The importance of considering genetic diversity in shark and ray conservation policies (2017, background): “Currently, there are more than 1160 validly named species of elasmobranchs in the world (Weigmann 2016), representing a significant number of apex and mesopredators that occupy top positions in the food chain (Heithaus et al. 2008; Ferretti et al. 2010).”
Global catches, exploitation rates, and rebuilding options for sharks (2013, background): “The loss, especially of larger apex predators, could and has led to unexpected disruptions of ecosystems and non-shark fisheries [30].”
Deep danger: intra-specific predation risk influences habitat use and aggregation formation of juvenile lemon sharks Negaprion brevirostris (2012, background): “In recent years the non-consumptive effects of predators have also been considered for marine communities (Dill et al. 2003, Trussell et al. 2004, Wirsing et al. 2008, Heithaus et al. 2008).”
Are we eating the world's megafauna to extinction? (2019, background): “…), is not shown eﬀects are transmitted both through consumptive and noncon-sumptive mechanisms, whereas the presence of megafauna predators fundamentally alters the behavior and distribution of prey species even in the absence of direct predation events (Heithaus, Frid, Wirsing, & Worm, 2008).”
Diversity in trophic interactions of green sea turtles Chelonia mydas on a relatively pristine coastal foraging ground (2011, positive): “The relatively low food quality of seagrass within Shark Bay as well as foraging constraints imposed by the presence of tiger sharks (e.g. Heithaus et al. 2007, 2008) may partially drive the apparently low importance of seagrass to the turtle population as a whole.”
Feeding ecology and niche segregation in oceanic top predators off eastern Australia (2010, background): “Understanding the trophic relationships of these predators underlies models that attempt to predict impacts of fishing and climate on other components of the ecosystem (e.g. Kitchell et al. 1999; Heithaus et al. 2008; Griffiths et al. 2010; Dambacher et al. in press).”
The ecological importance of intact top-predator populations: a synthesis of 15 years of research in a seagrass ecosystem (2012, background): “…of predators may equal or exceed the impacts of direct predation (Schmitz, Beckerman and O’Brien 1997; Lima 1998; Peacor and Werner 2000, 2001; Dill et al. 2003; Werner and Peacor 2003; Schmitz et al. 2004; Preisser et al. 2005; Wirsing et al. 2008a; Heithaus et al. 2008a, 2008b; Creel 2011).”
Dietary Niche Overlap in a Nearshore Elasmobranch Mesopredator Community (2011, positive): “In recent years, the loss of apex predators has received a great deal of attention because of the potential these predators have to influence systems through top-down control (Pace et al. 1999, Heithaus et al. 2008).”
Spatial responses to predators vary with prey escape mode (2010, background): “The propensity for predators to influence prey demography and trophic interactions via induced behaviour is now widely appreciated (Lima 1998; Preisser et al. 2005; Creel & Christianson 2008; Heithaus et al. 2008).”
Migratory marine species: their status, threats and conservation management needs (2014, background): “Heithaus et al. (2008) reviewed the ecosystem effects of the loss of marine top predators, many of them MMS, and found both direct mortality effects on the ecosystem (i.e. a possible population boom in the species they eat1Art I, 1, a: CMS Copyright # 2014 John Wiley & Sons, Ltd. Aquatic Conserv:…”
Stable isotope analysis as a tool for elasmobranch conservation research: a primer for non-specialists (2012, background): “Elasmobranchs can play important roles in structuring marine communities (Creel and Christianson 2008; Heithaus et al. 2008).”
Lower trophic levels and detrital biomass control the Bay of Biscay continental shelf food web: Implications for ecosystem management (2011, background): “In most cases, by targeting and reducing the abundance of high-value consumers, fisheries profoundly modify trophic networks and the flow of biomass (and energy) across the ecosystem, leading sometimes to trophic cascades (Heithaus et al., 2008) and ultimately to regime shifts (Daskalov et al.”
Foraging arena theory (2012, background): “…arena parameters (vulnerability exchange and predator rates of effective search), but also measuring how such rates change with risk-sensitive behavioural responses to major fishery-induced changes in abundances of larger predators (Heithaus et al. 2008), e.g., smaller fishes and inverte- 52 !”
Extinction of a shark population in the Archipelago of Saint Paul's Rocks (equatorial Atlantic) inferred from the historical record (2011, background): “A well-known phenomenon is the top-down trophic cascade that may occur after the release of prey from predatory control (reviews in Heithaus et al. (2008) and Baum and Worm (2009)).”
