Data from: Facultative asexual reproduction and genetic diversity of populations in the humivorous termite Cavitermes tuberosus

Denis Fournier, Simon Hellemans, Robert Hanus & Yves Roisin
Termite colonies are typically founded by a pair of sexually reproducing dispersers, which can sometimes be replaced by some of their offspring. Some Reticulitermes and Embiratermes species routinely practice asexual queen succession (AQS): the queen is replaced by neotenic daughters produced by parthenogenesis, which mate with the primary king. Here, to cast light on the evolution of AQS, we investigated another candidate species, Cavitermes tuberosus (Termitinae). Of 95 nests, 39 contained a primary queen and...

Data from: The assembly of ant-farmed gardens: mutualism specialization following host broadening

Guillaume Chomicki, Milan Janda & Susanne S. Renner
Ant-gardens (AGs) are ant/plant mutualisms in which ants farm epiphytes in return for nest space and food rewards. They occur in the Neotropics and Australasia, but not in Africa, and their evolutionary assembly remains unclear. We here use phylogenetic frameworks for important AG lineages in Australasia, namely the ant genus Philidris and domatium-bearing ferns (Lecanopteris) and flowering plants in the Apocynaceae (Hoya and Dischidia) and Rubiaceae (Myrmecodia, Hydnophytum, Anthorrhiza, Myrmephytum and Squamellaria). Our analyses revealed...

Data from: Network reorganization and breakdown of an ant–plant protection mutualism with elevation

Nichola S. Plowman, Amelia S.C. Hood, Jimmy Moses, Conor Redmond, Vojtech Novotny, Petr Klimeš, Tom M. Fayle & Amelia S. C. Hood
Both the abiotic environment and the composition of animal and plant communities change with elevation. For mutualistic species, these changes are expected to result in altered partner availability, and shifts in context-dependent benefits for partners. To test these predictions, we assessed the network structure of terrestrial ant-plant mutualists and how the benefits to plants of ant inhabitation changed with elevation in tropical forest in Papua New Guinea. At higher elevations, ant-plants were rarer, species richness...

Data from: Repeated intraspecific divergence in life span and aging of African annual fishes along an aridity gradient

Life span and aging are substantially modified by natural selection. Across species, higher extrinsic (environmentally related) mortality (and hence shorter life expectancy) selects for the evolution of more rapid aging. However, among populations within species, high extrinsic mortality can lead to extended life span and slower aging as a consequence of condition-dependent survival. Using within-species contrasts of eight natural populations of Nothobranchius fishes in common garden experiments, we demonstrate that populations originating from dry regions...

Data from: Assembling a species–area curve through colonization, speciation and human-mediated introduction

Evan P. Economo, Milan Janda, Benoit Guénard & Eli Sarnat
Aim: The fundamental biogeographical processes of colonization, speciation and extinction shape island biotas in space–time. On oceanic islands, area and isolation affect these processes and resulting biodiversity patterns. In the Anthropocene, a new human-mediated colonization dynamic is altering insular ecosystems world-wide. Here, we test predictions about the roles of archipelago area and isolation in structuring ant diversity patterns through effects on both natural and anthropogenic biogeographical processes. Location: Tropical Pacific islands. Methods: We compiled a...

Data from: When viruses don’t go viral: the importance of host phylogeographic structure in the spatial spread of arenaviruses

Sophie Gryseels, Stuart Baird, Rhodes Makundi, Benny Borremans, Herwig Leirs, Joelle Gouy De Bellocq & Stuart J. E. Baird
Many emerging infections are RNA virus spillovers from animal reservoirs. Reservoir identification is necessary for predicting the geographic extent of infection risk, but rarely are taxonomic levels below the animal species considered as reservoir, and only key circumstances in nature and methodology allow intrinsic virus-host associations to be distinguished from simple geographic (co-)isolation. We sampled and genetically characterized in detail a contact zone of two subtaxa of the rodent Mastomys natalensis in Tanzania. We find...
