Journal ArticleDOI
Herbivores and the Number of Tree Species in Tropical Forests
TL;DR: Any event that increases the efficiency of the predators at eating seeds and seedlings of a given tree species may lead to a reduction in population density of the adults of that species and/or to increased distance between new adults and their parents.
Journal ArticleDOI
The Ecology of Fruit Flies
TL;DR: The dominant feature of fruit fly research over the past decade has been a considerable preoccupation with projects related to the suppression or eradication of populations by the release of sterile individuals, with a strong preference for eradicative rather than "management" procedures.
Journal ArticleDOI
Fruit odor discrimination and sympatric host race formation in Rhagoletis
Charles E. Linn,Jeffrey L. Feder,Satoshi Nojima,Hattie R. Dambroski,Stewart H. Berlocher,Wendell L. Roelofs +5 more
TL;DR: It is shown that historically derived apple- and ancestral hawthorn-infesting host races of the fly use fruit odor as a key olfactory cue to help distinguish between their respective plants.
Journal ArticleDOI
Speciation via habitat specialization: the evolution of reproductive isolation as a correlated character
TL;DR: It is shown that disruptive selection on a continuous distribution of habitat preference can lead to the evolution of prezygotic reproductive isolation as a correlated character and the form of selection eliminates the major theoretical objections to the process of sympatric speciation.

Sympatric Speciation in Phytophagous Parasitic Insects
TL;DR: The appearance of new insect pests on economically important plants is a well-known phenomenon, but populations of introduced or native insects are frequently encountered which exhibit different host preferences, but which are morphologically indistinguishable from one another.

Journal ArticleDOI
Sympatric host race formation and speciation in frugivorous flies of the genus rhagoletis (diptera, tephritidae).
TL;DR: The objective of this paper is to point out how the biological attributes of these flies may have permitted new forms to arise rapidly in the absence of geographical barriers to gene flow.
Journal ArticleDOI
Host Plants as Islands in Evolutionary and Contemporary Time
TL;DR: It may be true that avian congeners are less likely to be able to coexist on islands than in comparable mainland areas, but it is not believed that this hypothesis receives any support from the data on the Tres Marias avifauna presented by Grant (1966).
Journal ArticleDOI
Genetic control of two pre-albumins in pigs.
TL;DR: A starch gel electrophoresis procedure which yields discrete separation of pre-albumins, transferrins and haptoglobins in pig serum is described, and evidence concerning the genetic mechanism underlying the prealbumin polymorphism which has been observed is presented.
