Avian Community Organization and Habitat Structure

Mary F. Willson
- 01 Aug 1974 - 
TL;DR: These results do not coincide with previous attempts at ecological generalization, and great care should be made of meticulously delineated subcommunities, resource measurement, and reproductive success, as well as events in the nonbreeding season.
Journal ArticleDOI

Pacific Salmon in Aquatic and Terrestrial Ecosystems

TL;DR: A review of the role of salmon in aquatic and terrestrial ecosystems can be found in this paper, where the authors describe the composition, magnitude, and distribution of marine inputs to freshwater and terrestrial systems via salmon.
Journal ArticleDOI

Flowering Ecology of Some Spring Woodland Herbs

TL;DR: It is suggested that flowering in early spring is a high-risk option in terms of insect- mediated sexual reproduction and constraints on flowering phenology are discussed, including the predictability of suitable conditions.
Journal ArticleDOI

The Influence of Habitats on Mating Systems of North American Passerine Birds

Jared Verner, +1 more
- 01 Jan 1966 - 
TL;DR: Regardless of sex ratio, a polygynous mating is expected to be adaptive for the females as well as for the male, and marshes and prairies are more likely than forests to present the minimum requisite food supply and sufficiently great differences in available food between territories for selection to favor polygyny.
Journal ArticleDOI

The evolution of inflorescence size in asclepias (asclepiadaceae).

TL;DR: This study centers on three sources of reproductive failure: failure of pod initiation, failure of fruit maturation, and failure to donate pollen, and focuses on intraspecific comparisons.
