In assemblages with greater parasite richness, lizard parasites from Atlantic Forest are able to increase their parasite abundance (per host), possibly through facilitated infection; however, the amplitude of infected hosts only expands in poor assemblage (lower parasite richness), which partially supports the ecological release hypothesis.

The Ecology of Adaptive Radiation

This volume is the ®rst of three volumes from a Festschrift marking the occasion of Richard C. Lewontin's 65th birthday and the approximate time of his retirement, and contains several chapters that were particularly noteworthy.

On the Role of Species in Anagenesis

It is proposed that because the spatial locations of habitats shift in time, extinction of and interbreeding among local populations makes much of the geographic differentiation of populations ephemeral, whereas reproductive isolation confers efficient permanence on morphological changes for them to be discerned in the fossil record, a consequence of speciation that supports a highly qualified version of punctuated equilibrium is pointed out.
