In social insects colony fitness is determined in part by individual worker phenotypes. Across ant species, colony size varies greatly and is thought to affect worker trait variation in both proximate and ultimate ways. Little is known about the relationship between colony size and worker trait evolution, but hypotheses addressing the role of socia...
Latitudinal diversity gradients are one of the most widely discussed patterns in global biogeography, generally in the context of high diversity in tropical regions. In contrast, ‘amphitropical’ or ‘inverse’ distributions, once thought to be unusual, are increasingly recognized as common among many hymenopteran insects. One such group is the ant ge...
Dorymyrmex Mayr 1866, the ‘pyramid ants’ or ‘cone ants’, are conspicuous inhabitants of arid landscapes across the Americas. Ranging from the Great Plains to Patagonia, they are concentrated north and south of the tropics in contrast to the latitudinal diversity gradient canon. Despite being frequently collected and ecologically important, Dorymyrm...
Dorymyrmex Mayr 1866, the “pyramid ants” or “cone ants,” are conspicuous inhabitants of arid landscapes across the Americas, found primarily in the temperate regions north and south of the tropics. Despite being frequently collected and ecologically important, they exemplify the taxonomic neglect typical in the subfamily Dolichoderinae. By targetin...
The pyramid ants (Dolichoderinae: Dorymyrmex) are commonly found all over the Americas, easily recognizable by their bullseye- or crater-shaped nests. Despite their pervasiveness, we know very little about these ants—even how many species exist. The morphological similarity of the Nearctic fauna has discouraged taxonomic revision until now, and Dor...
Austropurcellia, a genus of dispersal-limited arachnids endemic to isolated patches of coastal rainforest in Queensland, Australia, has a remarkable biogeographic history. The genus is a member of the family Pettalidae, which has a classical temperate Gondwanan distribution; previous work has suggested that Austropurcellia is an ancient lineage, wi...
The scorpion family Bothriuridae occupies a subset of landmasses formerly constituting East and West Gondwana, but its relationship to other scorpion families is in question. Whereas morphological data have strongly supported a sister group relationship of Bothriuridae and the superfamily Scorpionoidea, a recent phylogenomic analysis recovered a ba...
In our recent publication (Sharma et al., 2017), we tested the hypothesis that eggs attached to the legs of male Podoctidae (Opiliones, Laniatores) constituted a case of paternal care, using molecular sequence data in tandem with multiple sequence alignments to test the prediction that sequences of the eggs and the adults that carried them would in...
The Australian Wet Tropics in northern Queensland are heralded as a model region for studying the relationship between geological and evolutionary history. Mite harvestmen of the genus Austropurcellia (Opiliones: Cyphophthalmi: Pettalidae) have come to attention in recent years as a study system for understanding the biogeography of the Wet Tropics...
The genus Austropurcellia is a lineage of tiny leaf-litter arachnids that inhabit tropical rainforests throughout the eastern coast of Queensland, Australia. The majority of their diversity is found within the Wet Tropics rainforests of northeast Queensland, an area known for its exceptionally high levels of biodiversity and endemism. Studying the...
