A Primer of Ecology
With the aim of teaching students the essential models in population and community ecology, this book explains in detail the basic concepts of exponential and logistic population growth, age-structured demography, metapopulation dynamics, competition, predation and island biogeography.

SURVIVORSHIPSCHEDULES IN NATURE What are the different types of
survivorship curves observed in nature? There are three basic patterns. These
can be seen by plotting the logarithm of 13) on the y axis and age (x) on the x
of parental care in their offspring, ensuring high survivorship of young age
classes. The opposite, and more common, pattern is a “Type III" survivorship
curve. In this case, survivorship is very poor for the young age classes, but much
higher for ...
So, the traits expected under r-selection are early, semelparous reproduction,
large r, many offspring with poor survivorship, a Type III survivorship curve, and
small adult body size. By contrast, in K-selection, an organism is growing in an ...
