Data from: A phylogenomic perspective to diversity, hybridization and evolutionary affinities in the stickleback genus Pungitius

Guo Baocheng, Fang Bohao, Shikano Takahito, Momigliano Paolo, Wang Cui, Kravchenko Alexandra & Merilä Juha
Hybridization and convergent evolution are phenomena of broad interest in evolutionary biology, but their occurrence poses challenges for reconstructing evolutionary affinities among affected taxa. Sticklebacks in the genus Pungitius are a case in point: evolutionary relationships and taxonomic validity of different species and populations in this circumpolarly distributed species complex remain contentious due to convergent evolution of traits regarded as diagnostic in their taxonomy, and possibly also due to frequent hybridization among taxa. To clarify...

Data from: Within- and between-group dynamics in an obligate cooperative breeder

Rosie Woodroffe, Helen O'Neill & Daniella Rabaiotti
1. Cooperative behaviour can have profound effects on demography. In many cooperative species, components of fitness (e.g. survival, reproductive success) are diminished in smaller social groups. These effects (termed group-level component Allee effects) may lead smaller groups to grow relatively slowly or fail to persist (termed group-level demographic Allee effects). 2. If these group-level effects were to propagate to the population level, small populations would grow slowly or decline to extinction (termed population-level demographic Allee...

Data from: Transcriptome profiling of maternal stress-induced wing dimorphism in pea aphids

Lin Hu, Wanying Gui, Bing Chen & Li Chen
Wing dimorphism, i.e., wingless and winged forms, can be induced by maternal stress signals and is an adaptive response of aphids to environmental changes. Here, we investigated the ecological and molecular effects of three kinds of stress, namely, crowding, predation, and aphid alarm pheromone, on wing dimorphism. These three stressors induced high proportion of up to 60% of winged morphs in offspring. Transcriptome analysis of stress-treated female aphids revealed different changes in maternal gene expression...

Data from: Non-random latitudinal gradients in range size and niche breadth predicted by spatial patterns of climate

Erin E. Saupe, Corinne E. Myers, A. Townsend Peterson, Jorge Soberón, Joy Singarayer, Paul Valdes & Huijie Qiao
Aim. Tropical species are thought to experience and be adapted to narrow ranges of abiotic conditions. This idea has been invoked to explain a broad array of biological phenomena, including the latitudinal diversity gradient and differential rates of speciation and extinction. However, debate continues regarding the broad-scale applicability of this pattern and potential processes responsible. Here, we use a simulation approach to test two propositions: (1) strong geographic patterns of variation in realized niche breadth...
