Habitat use, movements and site fidelity of the gray smooth-hound shark (Mustelus californicus Gill 1863) in a newly restored southern California estuary (2011, background): “Site fidelity, seasonal patterns and population composition The use of bays and estuaries by coastal sharks may be related to foraging in highly productive habitats, mating or breeding (Bethea et al., 2004; Hueter et al., 2005; Chapman et al., 2009).”
Distribution and diet of four species of carcharhinid shark in the Hawaiian Islands: evidence for resource partitioning and competitive exclusion (2006, background): “The few studies that have attempted to investigate competition and resource partitioning between elasmobranchs have examined dietary and habitat overlap among sympatric species within small spatial scales (e.g. Cartamil et al. 2003, Bethea et al. 2004, White et al. 2004).”
Effects of body size, age and maturity stage on diet in a large shark: ecological and applied implications (2008, background): “Like in other sharks, individuals of all sizes preyed on small prey, but only large sharks were able to consume large prey (Chiaramonte and Pettovello 2000; Scharf et al. 2000; Bethea et al. 2004; Lucifora et al. 2006).”
Shark nursery areas: concepts, definition, characterization and assumptions (2007, background): “…2002, Bush 2003, Duncan & Holland 2006), sympatric coastal sharks (several taxa) in northwest Florida (e.g. Carlson & Brusher 1999, Carlson 2002, Bethea et al. 2004, Bethea et al. 2006), and blacktip sharks Carcharhinus limbatus in central west Florida (e.g. Heupel & Hueter 2001, 2002, Hueter…”
Feeding ecology and niche segregation in oceanic top predators off eastern Australia (2010, background): “Differences in the slopes of upper and lower edges indicate ontogenetic increases or decreases (depending on whether significant upper and lower bounds were diverging or converging) in trophic niche breadth (Scharf et al. 2000; Juanes 2003; Bethea et al. 2004).”
Comparative feeding ecology of four sympatric skate species off central California, USA (2007, background): “Differences in prey size have not been quantitatively evaluated for skates, but have been shown to vary among sharks (e.g., Bethea et al. 2004, 2005 ).”
Communal or competitive? Stable isotope analysis provides evidence of resource partitioning within a communal shark nursery (2011, background): “…within single species nursery areas is mounting, few studies have investigated resource partitioning among cooccurring shark species (Salini et al. 1992, Platell et al. 1998, Bethea et al. 2004, White et al. 2004), with only Bethea et al. (2004) focusing specifically on juveniles in these areas.”
Ontogenetic shifts in movement and habitat use of juvenile pigeye sharks Carcharhinus amboinensis in a tropical nearshore region (2011, background): “In particular for sharks, nearshore regions provide habitat for many different functions, including foraging and use of nursery areas (Castro 1993, Bethea et al. 2004, Heupel et al. 2007).”
Sharks in nearshore environments: models, importance, and consequences (2010, background): “Overlaps in diet have been reported be- tween many of these species (Simpfendorfer & Milward 1993, Bethea et al. 2004), which suggests that nearshore areas have sufficient productivity to support multiple shark species utilising the same or similar resources.”
Geographic and ontogenetic variation in the diet and daily ration of the bonnethead shark, Sphyrna tiburo, from the eastern Gulf of Mexico (2007, result): “By comparison, Bethea et al. (2003) reported 24, 49, and 50% empty stomachs for juvenile blacktip, C.”
Food habits and ontogenetic changes in the diet of the sandbar shark, Carcharhinus plumbeus, in Hawaii (2006, background): “In other studies on the diets of sharks, asymptotes were also not achieved for some species or size classes (Simpfendorfer 1998; Gelsleichter et al. 1999; Bethea et al. 2004).”
Sizing up the ecological role of sharks as predators (2014, result): “For example, studies have shown high overlap in diet between similar-sized sharks regardless of maturity state and species identity (e.g. Bethea et al. 2004).”
A nursery Area for Sharks and Rays in Northeastern Brazil (2006, background): “For elasmobranchs, dietary overlap (and therefore competition for food) is more enhanced among individuals of similar size than individuals of the same species (Springer 1967, Bethea et al. 2004 ).”
