Stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) in skin biopsy samples of four species in the Delphinidae family collected in 1993–2015 in the western North Pacific were investigated. Within the four species—common bottlenose, pantropical spotted, striped, and short-beaked common dolphins—δ13C and δ15N were highest in common bottlenose dolphins, and lowest in short-beaked common dolphins. Standard ellipse areas describing the likely range of the δ13C and δ15N, estimated using… Expand
Limited trophic partitioning among sympatric delphinids off a tropical oceanic atoll
Stable isotope evidence revealed surprisingly little evidence for trophic niche partitioning in the delphinid community of Palmyra Atoll compared to other studies, possibly because isotopes of prey are highly variable or insufficiently resolved to allow for differentiation. Expand
Trophic ecology and foraging areas of cetaceans sampled in the coastal waters of south-eastern Brazil assessed through skin δ13C and δ15N
Abstract We investigated the habitat use and feeding ecology of 10 cetacean species encountered along the south-eastern coast of Brazil (24–26°S) using carbon (δ13C) and nitrogen (δ15N) stableExpand
Niche partitioning amongst northwestern Mediterranean cetaceans using stable isotopes
It is suggested that this competition brought the striped dolphin to displace the common dolphin from part of its distribution range, restricting it to the southern fringe of the western Mediterranean and, particularly, to the Alboran Sea. Expand
Isotopic homogeneity throughout the skin in small cetaceans.
Isotopic homogeneity within the skin suggests that the isotope ratios of a sample from a specific skin position can be considered representative of the ratios from the entire skin tissue in dolphins, validates the results of previous stable isotope analyses in dolphins. Expand
Ecology and conservation of cetaceans in southern iberian waters
Esta tesis constituye una mejora sustancial en el conocimiento sobre la ecologia de los cetaceos al sur de la peninsula iberica que permitira desarrollar estrategias de conservacion mas adecuadasExpand


Investigating stock structure and trophic relationships among island-associated dolphins in the oceanic waters of the North Atlantic using fatty acid and stable isotope analyses
Differences in FA proportions, noticeably for FA of dietary origin, as well as in nitrogen SI profiles, confirmed that both species feed on distinct resources. Expand
Trophic Relationships and Habitat Preferences of Delphinids from the Southeastern Brazilian Coast Determined by Carbon and Nitrogen Stable Isotope Composition
Evidence of distinctive foraging habitats and the occupation of different ecological niches by these species in the study area is provided, with evidence of distinct feeding ecology of delphinids occurring in southeastern Brazil. Expand
Stable isotope analysis in two sympatric populations of bottlenose dolphins Tursiops truncatus: evidence of resource partitioning?
Bottlenose dolphins were divided into two putative populations based on previous genetic studies, and values of δ13C and δ15N differed significantly between these two groups, confirming the existence of population structuring. Expand
Geographical variations in the trophic ecology of Japanese anchovy, Engraulis japonicus, inferred from carbon and nitrogen stable isotope ratios
The present findings indicate the potential importance of the “inshore–offshore” variations in the biology of Japanese anchovy populations in the northwestern Pacific waters. Expand
Geographical variations in carbon and nitrogen stable isotope ratios in squid
The magnitude of geographical variations of stable isotope ratios of carbon and nitrogen was examined in ten squid species captured in seven areas of the world's oceans. The average of all 139 squidExpand
Stable isotope analysis reveals habitat partitioning among marine mammals off the NW African coast and unique trophic niches for two globally threatened species
Stable isotope abundances of carbon and nitrogen in the bone of 13 species of marine mammals from the northwest coast of Africa were investigated to assess their positions in the local trophic web and their preferred habitats, indicating that conservation of coastal and threatened species should be a priority. Expand
Spatial patterns of distribution, abundance, and species diversity of small odontocetes estimated using density surface modeling with line transect sampling
The results suggest that the species diversity of small odontocetes primarily follows general patterns of latitudinal and longitudinal gradients, while the confluence of faunas originating in distinct water masses increases species diversify in frontal waters around 30–40°N. Expand
The use of stable isotope analyses from skin biopsy samples to assess trophic relationships of sympatric delphinids off Moorea (French Polynesia)
It is suggested that stable isotopes reveal some degree of segregation and overlap within this delphinid community, however, fine-scale segregation processes may be concealed by stable isotope analyses, meaning that traditional dietary analyses investigations are complementary in answering questions related to niche segregation.

Ecological niche segregation within a community of sympatric dolphins around a tropical island
This study confirms that the use of multiple methodologies (habitat, behaviour and feeding ecology studies) help in discerning ecological niche segregation, especially when examining closely related species within a common restricted range. Expand
Biogeography of small odontocetes in relation to wide‐scale oceanographic structure in the North Pacific Ocean
It is indicated that large‐scale oceanographic structures are important determinants for the present patterns in biogeography and species diversity of small odontocetes. Expand
