Predation, natural selection and adaptation in an unusual threespine stickleback
THE study of biological variation in terms of the organism's adaptation to its environment is a most revealing approach to understanding diversity. This is exemplified in the classical studies of theExpand
The fishes and the aquatic environment of the central Amazon basin, with particular reference to respiratory patterns
This paper surveys the biology of central Amazonian fishes and the physicochemical conditions of their habitats, with particular emphasis on factors related to respiration, in order to place in anExpand
Morphology, life history, and ecology of an unusual stickleback (Gasterosteus aculeatus) in the Queen Charlotte Islands, Canada
In Mayer Lake Black sticklebacks shared an exposed environment with several predatory fish, whereas leiurus, the typical freshwater form of Gasterosteus aculeatus, was the only fish inhabiting theExpand
Influence of Egg Characteristics on Survival, Growth and Feeding in Larval Walleye (Stizostedion vitreum)
A subsample of eggs from 109 walleye (Stizostedion vitreum) from Crean Lake, Saskatchewan, was sieved soon after fertilization to yield four groups of eggs ranging in size from 4.86 to 5.62 mm3.Expand
Significance of Cannibalism in Larval Walleye (Stizostedion vitreum)
Cannibalism by larval walleye (Stizostedion vitreum) was studied to determine the ecological consequences and implications of cohort cannibalism in intensive culture systems and in naturalExpand
Phenetic Variation and Habitat Differences in Gasterosteus Populations of the Queen Charlotte Islands
Moodie, G. E. E., and T. E. Reimchen (Department of Biology, University of Winnipeg, Winnipeg, Manitoba, R3B 2E9, Canada) 1976. Phenetic variation and habitat differences in Gasterosteus populationsExpand

Threespine sticklebacks (Gasterosteus aculeatus) usually breed in large colonies during the spring and summer in the shallows of lakes and streams. Males build nests, defend territories, courtExpand
Heat production and pollination in Araceae
The ecological role of heat production in Araceae has not been extensively investigated. The possibility that carbon dioxide and heat production are components of a carrion, dung, and mammal mimicryExpand
Territoriality and courtship in the Olympic mudminnow (Novumbra hubbsi)
Male Novumbra hubbsi are highly aggressive during reproduction when they hold very large territories over long periods of time. A description of aggressive displays, territoriality, and courtship isExpand
Method for the Intensive Culture of Walleye
Abstract Techniques were developed to rear larval walleyes (Stizostedion vitreum) successfully through the first 30 d, the current bottleneck in the intensive culture of this species. Fish wereExpand
