abstract = {Symbioses include some of the clearest cases of coevolution, but their origin,
loss or reassembly with different partners can rarely be inferred. Here we
use ant/plant symbioses involving three plant clades to investigate the evolution
of symbioses. We generated phylogenies for the big-eyed arboreal ants
(Pseudomyrmecinae), including 72% of their 286 species, as well as for five
of their plant host groups, in each case sampling more than 61% of the species.
We show that the ant-housing Vachellia (Mimosoideae) clade and its ants
co-diversified for the past 5 Ma, with some species additionally colonized
by younger plant-nesting ant species, some parasitic. An apparent co-radiation
of ants and Tachigali (Caesalpinioideae)was followed bywaves of colonization
by the same ant clade, and subsequent occupation by a younger ant group.
Wide crown and stem age differences between the ant-housing genus Triplaris
(Polygonaceae) and its obligate ant inhabitants, and stochastic trait mapping,
indicate that its domatium evolved earlier than the ants now occupying it,
suggesting previous symbioses that dissolved. Parasitic ant species evolved
from generalists, not from mutualists, and are younger than the mutualistic
systems they parasitize. Our study illuminates the macroevolutionary assembly
of ant/plant symbioses, which has been highly dynamic, even in very
specialized systems.}
