Phylogeny of the Ants: Diversification in the Age of Angiosperms
TLDR
Divergence time estimates calibrated by minimum age constraints from 43 fossils indicate that most of the subfamilies representing extant ants arose much earlier than previously proposed but only began to diversify during the Late Cretaceous to Early Eocene, which also witnessed the rise of angiosperms and most herbivorous insects. Expand
CODIVERSIFICATION IN AN ANT‐PLANT MUTUALISM: STEM TEXTURE AND THE EVOLUTION OF HOST USE IN CREMATOGASTER (FORMICIDAE: MYRMICINAE) INHABITANTS OF MACARANGA (EUPHORBIACEAE)
TLDR
The inferred timeline based on cytochrome oxidase I divergence rates concurs with independent biogeographical events in the region reconstructed from palynological data, thus suggesting that the evolutionary histories of Decacrema and their Pachystemon hosts have been contemporaneous since the mid‐Miocene. Expand
The ecology and evolution of ant association in the Lycaenidae (Lepidoptera).
TLDR
Both demographic and phylogenetic evidence indicate that ant association has shaped the evolution of obligately associated groups, and further research on phylogeny and natural history, particularly of the Neotropical fauna, will be necessary to understand the role ants have played in the Evolution of the Lycaenidae. Expand
Animals in a bacterial world, a new imperative for the life sciences
TLDR
Recent technological and intellectual advances that have changed thinking about five questions about how have bacteria facilitated the origin and evolution of animals; how do animals and bacteria affect each other’s genomes; how does normal animal development depend on bacterial partners; and how is homeostasis maintained between animals and their symbionts are highlighted. Expand
Molecular phylogeny and systematics of the Pieridae (Lepidoptera: Papilionoidea): higher classification and biogeography
TLDR
A reclassification of the subfamily Pierinae into two tribes is proposed, corroborating Ehrlich’s 1958 phenetic hypothesis and arguing for an origin of the two subfamilies in western Gondwana (Africa + South America) during the Late Cretaceous. Expand
Dating the origin of the Orchidaceae from a fossil orchid with its pollinator
TLDR
An exquisitely preserved orchid pollinarium attached to the mesoscutellum of an extinct stingless bee recovered from Miocene amber in the Dominican Republic, that is 15–20 million years old, constitutes both the first unambiguous fossil of Orchidaceae and an unprecedented direct fossil observation of a plant–pollinator interaction. Expand
Bacterial gut symbionts are tightly linked with the evolution of herbivory in ants
TLDR
The hypothesis that bacteria have facilitated convergent evolution of herbivory across the ants is supported, further implicating symbiosis as a major force in ant evolution. Expand
Phylogeny of Agrodiaetus Hübner 1822 (Lepidoptera: Lycaenidae) inferred from mtDNA sequences of COI and COII and nuclear sequences of EF1-alpha: karyotype diversification and species radiation.
TLDR
The authors' data indicate that Agrodiaetus is monophyletic, and representatives of the genus Polyommatus (sensu stricto) are the closest relatives. Expand
A castration parasite of an ant–plant mutualism
TLDR
It is reported that the primary ant symbiont, Allomerus cf. Expand
The evolution of alternative parasitic life histories in large blue butterflies
TLDR
The phylogeny for the large blue (Maculinea) butterflies group is presented, which shows that it is a monophyletic clade nested within Phengaris, a rare Oriental genus whose species have similar life histories. Expand
