Data from: Stable isotopes reveal differences in diet among reed bunting subspecies that vary in bill size
- 负责人：
- DOI：
- doi:10.5061/dryad.p3nt7
- 摘要：
- (carbon and nitrogen) were performed to assess their foraging niches. Stable isotope analyses of potential food items confirmed uniform baseline isotopic composition amo
Data from: Limited trophic partitioning among sympatric delphinids off a tropical oceanic atoll

- 摘要：
- community structure and dynamics. In this study, we used stable isotope analysis of skin biopsies to compare the isotopic, and thus, trophic niches of three sympatric
Data from: Unravelling the role of allochthonous aquatic resources to food web structure in a tropical riparian forest

- DOI：
- doi:10.5061/dryad.7gr50
- 摘要：
- e spider families had very low overlap between treatments, and others had wider isotopic niches in the control than exclusion treatment. Mos
Data from: Sequential stable isotope analysis reveals differences in dietary history of three sympatric equid species in the Mongolian Gobi

- 摘要：
- livestock densities. We used stable isotope chronologies of tail hairs to draw inferences about multi-year diet seasonality, isotopic dietary niches
Data from: Generalist predator's niche shifts reveal ecosystem changes in an experimentally fragmented landscape
- 负责人：
- DOI：
- doi:10.5061/dryad.56b81
- 摘要：
- fragmentation among continuous forest, fragments, and matrix habitats. We predicted that in fragments and the matrix, isotopic niches would shift due to decreases
Data from: Trophic niche similarities of sympatric Turdus thrushes determined by fecal contents, stable isotopes, and bipartite networks approaches
- 负责人：
- DOI：
- doi:10.5061/dryad.np5hqbzqd
- 摘要：
- species. Turdus amaurochalinus and T. albicollis had the greatest trophic and isotopic niche overlap, with 90% and 20% overlap, respectively. Ther
Data from: Seasonal and annual differences in the foraging ecology of two gull species breeding in sympatry and their use of fishery discards
- 负责人：
- Calado, Joana G.
- DOI：
- doi:10.5061/dryad.m8t2k
- 摘要：
- s the yellow-legged gull showed a broader isotopic niche width than Audouin’s gull in 2013, and in 2014 the two gull species exhibited different isotopic niche
Data from: Global test of Eltonian niche conservatism of nonnative freshwater fish species between their native and introduced ranges
- 负责人：
- DOI：

- 摘要：
- rall isotopic niche breadth. Using an assemblage centroid standardized isotope vector analysis and controlling for phylogenetic relatedness among species
Data from: Trophic response to ecological conditions of habitats: evidence from trophic variability of freshwater fish

- DOI：
- doi:10.5061/dryad.v15dv41s7
- 摘要：
- in the scenopoetic and bionomic views, as isotopic niche width. 2. We applied compound-specific isotope analysis (CSIA) of nitrogen within amino acids to understand
Data from: Community structure of a Neotropical bat fauna as revealed by stable isotope analysis: Not all species fit neatly into predicted guilds
- 负责人：
- DOI：
- doi:10.5061/dryad.88sf103
- 摘要：
- t (1) interspecific variation in isotopic overlap would be greater within guilds than between guilds, and (2) no two sympatric populations would have isotopic niches that overlap
