Changes in ocean conditions in response to climate variability and density-dependent factors are increasingly recognized as primary determinants of spatiotemporal dynamics of spawning in small pelagic ...

Like predation and competition, recognition of mutualisms' functional responses and consumer-resource interactions provides new insights into their density-dependent population dynamics. Fluctuations ...

Solomon and Varley 1 did well to direct attention to the confusion that accompanies the ecological term ‘density-dependent factors’. Howard and Fiske's 2 original idea that the multiplication of ...

Return to Main Index page Go back to notes for Lecture 26, 1 and 3-Apr-13 Go forward to lecture 28 8-Apr-13 We now turn to something that has been an implied theme throughout -- population regulation.

We studied the effects of different parasite and host densities on the feeding success of larval Ixodes scapularis ticks upon white-footed mice Peromyscus leucopus. Mice were infested daily with 10, ...

S-shaped curve: The population initially grows exponentially, but as it approaches carrying capacity, the growth rate slows ...
