Ecological Aspects of Amphibian Metamorphosis
A synthetic theory of the ecology of amphibian metamorphosis is founded on the observation that the large variation in length of larval period and body size at metamorphosis typical of a particularExpand

Regulation of Structure in Complex Systems: Experimental Temporary Pond Communities
Interactions among competition, predation, and disturbance in determining the abundances of four species of anurans were studied in a factorial experiment using 36 replicated experimental ponds.Expand

EXPERIMENTAL ECOLOGY OF FOOD WEBS: COMPLEX SYSTEMS IN TEMPORARY PONDS
A food web graphically represents the paths of nutrients and energy through the living components of an ecosystem and the context in which individuals exploit their prey and avoid their enemies.Expand

The Evolutionary and Mathematical Demography of the Turtle Chrysemys picta
A mark—recapture study of a population of painted turtles, Chrysemys picta, started by O. J. Sexton between 1953 and 1957 was continued between 1968 and 1973. Life tables are constructed and aExpand

Competition, Predation, and the Structure of the Ambystoma-Rana Sylvatica Community
Populations of six species of amphibians were manipulated in field enclosures to study the biological tractability of current concepts of the organization of natural communities. ExperimentalExpand

Choice of Oviposition Site by Hyla Chrysoscelis: Role of Predators and Competitors
The role of predators and competitors in the choice of oviposition site by the treefrog Hyla chrysoscelis was examined in a randomized complete block experiment using 90 replicated experimentalExpand

PAEDOMORPHOSIS IN AMBYSTOMA TALPOIDEUM: MAINTENANCE OF POPULATION VARIATION AND ALTERNATIVE LIFE‐HISTORY PATHWAYS
A “common garden” experiment using artifical ponds was performed to test if differences in frequency of paedomorphosis and metamorphosis among six natural populations of the salamander AmbystomaExpand

EVOLUTIONARY STRATEGIES IN LIZARD REPRODUCTION
Several investigators have dealt in a theoretical way with the evolution of reproductive rates and attendant life history phenomena (Cole, 1954; Lack, 1954, 1966, 1968; Murphy, 1968; Svardson, 1949;Expand

Density‐Dependent Aspects of Growth and Metamorphosis in Bufo Americanus
Larvae of Bufo americanus (Anura: Bufonidae) were reared at controlled densities and food levels in laboratory populations and at controlled densities in enclosures in a farm pond in one— andExpand
