The coevolutionary dynamics of obligate ant social parasite systems-between prudence and antagonism

Article Abstract:

Obligate social parasite systems are ideal models for coevolution since the close phylogenetic relationship between the parameters and their hosts results in similar evolutionary potentials, making adaptations in a stepwise fashion especially likely to occur. The evolutionary dynamics of host-parasite interactions are influenced by a number of parameters such as the parasite's transmission mode and rate, the generic structure of host and parasite populations, the antagonists' migration rates, and the degree of mutual specialization.

The role of eyespots as anti-predator mechanisms, principally demonstrated in the lepidoptera

Article Abstract:

The role of eyespots as antipredator mechanisms and the related hypothesis are reviewed. The necessity to consider the potential influence of sexual selection on lepidopteran wing patterns and the genetics and development of eyespot formation are discussed.

Complex interactions among mammalian carnivores in Australia, and their implications for wildlife management

Article Abstract:

A study on the complex interactions among mammalian carnivores in Australia, and their implications for wildlife management are presented. Interactions within the mammalian carnivore guild are common, widespread and can be profound in their effects.
