Abstract: 

One of the major tasks in evolutionary ecology is to explain how
interspecific interactions influence the dynamics of evolutionary
processes and enable radiation and genesis of biological diversity. The
bewildering diversity of dog roses is generated by a heterogamous
reproductive system. Genetic distance between rose taxa was analysed as
base line for the explanation of subsequent radiation of the two
host-dependent parasite groups, rust fungi and insects. We investigated
the interaction between each host–parasite system and between the
parasite groups. We learned that the functional diploidy at the meiotic
level is not reflected at the phenotypic level in dog roses. The
phytophagous insect community shows only minor differences in
composition on different rose species. These invertebrates seem not to
be negatively affected by glandular trichomes, but for the rust fungi, Phragmidium
glandular trichomes matter, because they are negatively correlated with
the infection. The abundance of two rose specialists, the rose hip fly Rhagoletis alternata Fall. and the rose gall wasp Diplolepis rosae L., differed on rose species, but Rh. alternata
showed neither any genetic differentiation on host species nor
geographical differentiation. As a basic result, we detected that
genetic diversity of dog roses is not translated into a host-specific
radiation of the parasites. We assume that intensive reticulate
evolution of dog roses prevents co-speciation.
