- Communal or competitive? Stable isotope analysis provides evidence of resource partitioning within a communal shark nursery (2011, background): “…(Domi et al. 2005, MacNeil et al. 2005, 2006); (3) sampling multiple tissues can provide distinct timeframes due to differences in tissue turnover rates (Kurle & Worthy 2002, MacNeil et al. 2005); and (4) samples from several different tissues can be obtained without the need to euthanize animals.”
- Stable isotope analysis reveals pelagic foraging by the Southern sea lion in central Chile (2007, methodology): “Samples were then rinsed with ether petroleum to extract remaining lipids (Kurle and Worthy, 2002), followed by a second washing with distilled water again and dried at 60 °C for 48 h.”
- Using stable isotope biogeochemistry to study marine mammal ecology (2010, background): “Lipid extraction is especially important in the interpretation of experiments designed to determine trophic or tissue-specific discrimination factors (Hobson et al. 1996, Kurle 2002, Kurle and Worthy 2002, Lesage et al. 2002, Zhao et al. 2006, Stegall et al. 2008).”
- Variability in fatty acid composition of bottlenose dolphin (Tursiops truncatus) blubber as a function of body site, season, and reproductive state (2004, background): “Stable isotopes have been successfully used to determine dietary habits of many vertebrate species, including marine mammals (Gilmour et al. 1995; Pond et al. 1995; Smith et al. 1996; Kurle and Worthy 2001, 2002 ).”
- Stable isotopes from multiple tissues reveal diet switching in sharks (2005, background): “This result implies that the fishes had been near steady-state with their diet during the previous year where — using the time to 95% turnover estimates for muscle (488 d) and liver (239 d) of MacNeil et al. (2005) — there was agreement between tissues.”
- Trophic relationships along a bathymetric gradient at the deep-sea observatory HAUSGARTEN (2009, background): “…and temporary starvation may have contributed to the broad range observed as it can lead to an enrichment of d15N in animal tissues (Hobson et al., 1993; Frazer et al., 1997; Adams and Sterner, 2000; Kurle and Worthy, 2002; Olive et al., 2003; Cherel et al., 2005; Gaye-Siessegger et al., 2007).”
