| cryptic dietary components reduce dietary overlap among sympatric butterflyfishes (chaetodontidae). | this study used three different methods to ascertain dietary composition for 21 chaetodontidae species co-occurring on a single fringing reef in derawan island, east kalimantan, indonesia. the combination of in situ feeding observations, examination of gut contents and stable-isotope analyses was expected to identify previously unresolved prey items that contribute to dietary separation. in situ feeding observations identified five species that feed predominantly on anthozoans (chaetodon barones ... | 2009 | 20738604 |
| does genetic distance between parental species influence outcomes of hybridization among coral reef butterflyfishes? | christmas island is located at the overlap of the indian and pacific ocean marine provinces and is a hot spot for marine hybridization. here, we evaluate the ecological framework and genetic consequences of hybridization between butterflyfishes chaetodon guttatissimus and chaetodon punctatofasciatus. further, we compare our current findings to those from a previous study of hybridization between chaetodon trifasciatus and chaetodon lunulatus. for both species groups, habitat and dietary overlap ... | 2014 | 24750170 |
