Data from: Ecological incumbency impedes stochastic community assembly in Holocene foraminifera from the Huon Peninsula, Papua New Guinea

Claire E. Reymond, Michael Bode, Willem Renema & John M. Pandolfi
Persistence in the structure of ecological communities can be predicted both by deterministic and by stochastic theory. Evaluating ecological patterns against the neutral theory of biodiversity provides an appropriate methodology for differentiating between these alternatives. We traced the history of benthic foraminiferal communities from the Huon Peninsula, Papua New Guinea. From the well-preserved uplifted reef terrace at Bonah River we reconstructed the benthic foraminiferal communities during a 2200-year period (9000–6800 yr B.P.) of reef building...

Data from: Testing the impact of calibration on molecular divergence times using a fossil-rich group: the case of Nothofagus (Fagales)

Although temporal calibration is widely recognized as critical for obtaining accurate divergence-time estimates using molecular dating methods, few studies have evaluated the variation resulting from different calibration strategies. Depending on the information available, researchers have often used primary calibrations from the fossil record or secondary calibrations from previous molecular dating studies. In analyses of flowering plants, primary calibration data can be obtained from macro- and mesofossils (e.g., leaves, flowers, and fruits) or microfossils (e.g., pollen)....

Data from: The molecular genetics of clinal variation: a case study of ebony and thoracic trident pigmentation in Drosophila melanogaster from eastern Australia

Marina Telonis-Scott, Ary A Hoffmann & Carla M Sgrò
Widespread pigmentation diversity coupled with a well-defined genetic system of melanin synthesis and patterning in Drosophila provides an excellent opportunity to study phenotypes undergoing evolutionary change. Pigmentation variation is highly correlated with different ecological variables and is thought to reflect adaptations to different environments. Several studies have linked candidate genes from D. melanogaster to intra-population variation and interspecific morphological divergence, but less clearly to variation among populations forming pigmentation clines. We characterised a new thoracic...

Data from: Sexual selection is positively associated with ecological generalism among agamid lizards

Örjan Östman & Devi Stuart-Fox
Natural and sexual selection shape the evolution of species, but the interplay between them is poorly understood. Two phylogenetic studies on birds have suggested that species with greater sexual dichromatism use more habitats. Here, we show that in Agamid lizards, species with more elaborate secondary sexual traits also are ecologically more opportunistic. Species with greater dimorphism in head size and ornamentation have greater altitudinal range and occupy more habitats, respectively, and species with greater sexual...

Data from: Wings or winds: inferring bat migration in a stepping-stone archipelago

Nicole Weyeneth, Steven M Goodman, Belinda Appleton, Rebecca Wood & Manuel Ruedi
Eocene ocean currents and prevailing winds correlate with over-water dispersals of terrestrial mammals from Africa to Madagascar. Since the Early Miocene (about 23 Ma), these currents flowed in the reverse direction, from the Indian Ocean towards Africa. The Comoro Islands are equidistant between Africa and Madagascar and support an endemic land vertebrate fauna that shares recent ancestry predominantly with Madagascar. We examined whether gene flow in two Miniopterus bat species endemic to the Comoros and...

Data from: Polymorphism in the couch potato gene clines in eastern Australia but is not associated with ovarian dormancy in Drosophila melanogaster

Siu Fai Lee, Carla M Sgrò, Jennifer Shirriffs, Choon Wei Wee, Lea Rako, Belinda Van Heerwaaden & Ary A Hoffmann
Natural selection can generate parallel latitudinal clines in traits and gene frequencies across continents but these have rarely been linked. An amino acid (isoleucine to lysine, or I462K) polymorphism of the couch potato (cpo) gene in Drosophila melanogaster is thought to control female reproductive diapause cline in North America (Schmidt et al. 2008). Here, we show that under standard diapause inducing conditions (12 °C and short photoperiod) (Saunders et al. 1989), egg maturation in Australian...
