Data from: Local adaptation of reproductive performance during thermal stress

Damiano Porcelli, Kevin J. Gaston, Roger K. Butlin & Rhonda R. Snook
Considerable evidence exists for local adaptation of critical thermal limits in ectotherms following adult temperature stress, but fewer studies have tested for local adaptation of sublethal heat stress effects across life-history stages. In organisms with complex life cycles, such as holometabolous insects, heat stress during juvenile stages may severely impact gametogenesis, having downstream consequences on reproductive performance that may be mediated by local adaptation, although this is rarely studied. Here, we tested how exposure to...

Data from: Sexual selection and assortative mating: an experimental test

Allan Debelle, Michael G. Ritchie & Rhonda R. Snook
Mate choice and mate competition can both influence the evolution of sexual isolation between populations. Assortative mating may arise if traits and preferences diverge in step, and, alternatively, mate competition may counteract mating preferences and decrease assortative mating. Here, we examine potential assortative mating between populations of Drosophila pseudoobscura that have experimentally evolved under either increased (‘polyandry’) or decreased (‘monogamy’) sexual selection intensity for 100 generations. These populations have evolved differences in numerous traits, including...

Data from: Targeted resequencing reveals geographical patterns of differentiation for loci implicated in parallel evolution

Anja M. Westram, Marina Panova, Juan Galindo & Roger K. Butlin
Parallel divergence and speciation provide evidence for the role of divergent selection in generating biological diversity. Recent studies indicate that parallel phenotypic divergence may not have the same genetic basis in different geographical locations - “outlier loci” (loci potentially affected by divergent selection) are often not shared among parallel instances of phenotypic divergence. However, limited sharing may be due, in part, to technical issues if false positive outliers occur. Here, we test this idea in...

Data from: How big is it really? Assessing the efficacy of indirect estimates of body size in Asian elephants

Simon N. Chapman, Hannah S. Mumby, Jennie A.H. Crawley, Khyne U. Mar, Win Htut, Aung Thura Soe, Htoo Htoo Aung, Virpi Lummaa & Jennie A. H. Crawley
Information on an organism’s body size is pivotal in understanding its life history and fitness, as well as helping inform conservation measures. However, for many species, particularly large-bodied wild animals, taking accurate body size measurements can be a challenge. Various means to estimate body size have been employed, from more direct methods such as using photogrammetry to obtain height or length measurements, to indirect prediction of weight using other body morphometrics or even the size...

Data from: C4 photosynthesis boosts growth by altering physiology, allocation and size

Rebecca R. L. Atkinson, Emily J. Mockford, Christopher Bennett, Pascal-Antoine Christin, Elizabeth L. Spriggs, Robert P. Freckleton, Ken Thompson, Mark Rees & Colin P. Osborne
C4 photosynthesis is a complex set of leaf anatomical and biochemical adaptations that have evolved more than 60 times to boost carbon uptake compared with the ancestral C3 photosynthetic type1,​2,​3. Although C4 photosynthesis has the potential to drive faster growth rates4,5, experiments directly comparing C3 and C4 plants have not shown consistent effects1,6,7. This is problematic because differential growth is a crucial element of ecological theory8,9 explaining C4 savannah responses to global change10,11, and research...

Data from: Intra-ejaculate sperm selection in female zebra finches

Nicola Hemmings, Clair Bennison & Timothy R. Birkhead
Among internal fertilizers, typically fewer than 1% sperm survive the journey through the oviduct. Several studies suggest that the sperm reaching the ovum—the ‘fertilizing set’—comprise a non-random sub-population, but the characteristics of this group remain unclear. We tested whether oviductal selection in birds results in a morphologically distinct subset of sperm, by exploiting the fact that the fertilizing set are trapped by the perivitelline layer of the ovum. We show that these sperm have remarkably...

Data from: Genome-wide differentiation in closely related populations: the roles of selection and geographic isolation

Rebecca J. Safran, Elizabeth S. C. Scordato, Matthew R. Wilkins, Joanna K. Hubbard, Brittany R. Jenkins, Tomas Albrecht, Samuel M. Flaxman, Hakan Karaardic, Yoni Vortman, Arnon Lotem, Patrik Nosil, Péter Pap, Sheng-Feng Shen, Shih-Fan Chan, Thomas L. Parchman, Nolan C. Kane, S.-F. Chan & T.L. Parchman
Population divergence in geographic isolation is due to a combination of factors. Natural and sexual selection may be important in shaping patterns of population differentiation, a pattern referred to as ‘isolation by adaptation’ (IBA). IBA can be complementary to the well-known pattern of ‘isolation by distance’ (IBD), in which the divergence of closely related populations (via any evolutionary process) is associated with geographic isolation. The barn swallow Hirundo rustica complex comprises six closely related subspecies,...
