Getting to the fat of the matter: models, methods and assumptions for dealing with lipids in stable isotope analyses
Within an organism, lipids are depleted in 13C relative to proteins and carbohydrates (more negative δ13C), and variation in lipid content among organisms or among tissue types has the potential toExpand

Can stable isotope ratios provide for community-wide measures of trophic structure?
Stable isotope ratios (typically of carbon and nitrogen) provide one representation of an organism's trophic niche and are widely used to examine aspects of food web structure. Yet stable isotopesExpand

The ecological causes of individual specialisation.
Many generalist populations are composed of specialised individuals, whose niches are small subsets of the population niche. This 'individual specialisation' is a widespread phenomenon in naturalExpand

Applying stable isotopes to examine food‐web structure: an overview of analytical tools
Stable isotope analysis has emerged as one of the primary means for examining the structure and dynamics of food webs, and numerous analytical approaches are now commonly used in the field.Expand

Niche width collapse in a resilient top predator following ecosystem fragmentation
Much research has focused on identifying species that are susceptible to extinction following ecosystem fragmentation, yet even those species that persist in fragmented habitats may haveExpand

PREDATOR‐DRIVEN PHENOTYPIC DIVERSIFICATION IN GAMBUSIA AFFINIS
Abstract Predation is heterogeneously distributed across space and time, and is presumed to represent a major source of evolutionary diversification. In fishes, fast‐starts–udden, high‐energyExpand

Nursery function of tropical back-reef systems
Similar to nearshore systems in temperate latitudes, the nursery paradigm for tropical back-reef systems is that they provide a habitat for juveniles of species that subsequently make onto- geneticExpand

Habitat‐associated morphological divergence in two Neotropical fish species
We examined intraspecific morphological diversification between river channel and lagoon habitats for two Neotropical fish (Bryconops caudomaculatus, Characidae; Biotodoma wavrini, Cichlidae). WeExpand

Marine nurseries and effective juvenile habitats: concepts and applications
Much recent attention has been focused on juvenile fish and invertebrate habitat use, particularly defining and identifying marine nurseries. The most significant advancement in this area has beenExpand

Contrasting patterns of individual specialization and trophic coupling in two marine apex predators.
1. Apex predators are often assumed to be dietary generalists and, by feeding on prey from multiple basal nutrient sources, serve to couple discrete food webs. But there is increasing evidence thatExpand
