Species that appear highly specialized on the basis of their phenotype (e.g., morphology, behavior, and physiology) also sometimes act as ecological generalists. This apparent paradox has been used to argue against the importance of competition as a diversifying evolutionary force. We provide an alternative explanation based on optimal foraging theory. Some resources are intrinsically easy to use and are widely preferred, while others require specialized phenotypic traits on the part of the… 
Individual foraging specialization: niche width versus niche overlap
TLDR
Similar to traditional approaches to generalization and specialization, individual specialization should describe individual niche use only in terms relative to the population’s niche use.
On folivory, competition, and intelligence: generalisms, overgeneralizations, and models of primate evolution
  • K. Sayers

TLDR
This paper examines the behavior of primate folivore–frugivores, with particular emphasis on gray langurs, within the broader context of evolutionary ecology, and examines the assumptions and predictions of behavioral, socioecological, and cognitive evolutionary models.
Increased competition as a cost of specialization during the evolution of resource polymorphism
TLDR
It is hypothesized that the greater intramorph competition faced by specialists stems ultimately from functional limitations associated with trophic specialization, which prevent specialists from switching to alternative resources when their resource is depleted.
Intraspecific competition affects the strength of individual specialization : an optimal diet theory method
Question: Why would individuals that inhabit the same environment choose to feed on different subsets of the available resources? Mathematical method: We outline a flexible model that combines
Mechanistic analysis of interspecific competition using foraging trade-offs: implications for duck assemblages.
TLDR
Mechanistic models that predict filter-feeding performance for seven species of ducks directly from bill morphology and kinetics are constructed and it is predicted that species should share a preference for their most profitable prey while partitioning their less profitable prey by size.
The Ecology of Individuals: Incidence and Implications of Individual Specialization
TLDR
The collection of case studies suggests that individual specialization is a widespread but underappreciated phenomenon that poses many important but unanswered questions.
Network analysis reveals contrasting effects of intraspecific competition on individual vs. population diets.
TLDR
A new method based on complex network theory that moves beyond a simple measure of diet breadth is presented and reveals that the population as a whole added new types of prey as stickleback density was increased, consistent with foraging theory.
Darwin's finches and their diet niches: the sympatric coexistence of imperfect generalists
TLDR
The results together suggest that the ground finches are ‘imperfect generalists’ that use overlapping resources under benign conditions, but then retreat to resources for which they are best adapted during periods of food limitation, which likely promote local and regional coexistence.
Integration of Versatile Functional Design, Population Ecology, Ontogeny and Phylogeny
TLDR
It is emphasized that examination of early life history stages holds important information about the adaptive significance of diverse structures, including the effect of prey availability and the effects of captivity, when assessing the functional repertoire of fishes.
Opportunism and cognition in birds
Animals vary in their response to the distribution of resources in time and space. Opportunistic foraging is evident in many species and has indirectly been shown to be linked to measures of

Competition and food selection field tests of a theory
TLDR
A graphical model describing the optimal choices of two species competing for resources in two types of habitats is tested with hummingbirds in the field, finding that the dominant's aggressive behavior forced the subordinate to restrict itself to a patch type known to be inferior.
The Coevolution and Stability of Competing Species
TLDR
For the cases considered, the co-evolved divergence of the consumers leads to greater global stability of the consumer community even though it has negligible effect on the local Lyapunov stability.
Species Packing and Niche Complementarity in Three Sunfishes
  • E. Werner
  • Environmental Science
    The American Naturalist
  • 1977
TLDR
A method to relate foraging theory to species-packing theory is developed and it is predicted that these species occupy similar habitats and segregate on the food size axis while the third species, which is intermediate in morphology, should be excluded from these habitats and show complementarity on niche dimensions.
EVIDENCE FOR ECOLOGICAL CHARACTER DISPLACEMENT IN WESTERN AMERICAN CATOSTOMID FISHES
TLDR
The weakness of the available evidence for competitive character displacement lies in the difficulty of establishing unambiguously that the character state of a species changes under natural selection arising from the presence of one or more species similar to it ecologically.
A Theory of Habitat Selection
TLDR
It is shown that at the equilibrium point of this coexistence, there may be no overt competition remaining, and a modified definition of interspecific competition is suggested.

TLDR
Contingency models of feeding compare the energy per unit time gained from utilizing a resource unit of a particular kind against that energy/time expected if the unit is skipped, implying that temporal resource partitioning on a diel basis should be relatively rare.
