Data from: Genomics of invasion: diversity and selection in introduced populations of monkeyflowers (Mimulus guttatus)

Joshua Puzey & Mario Vallejo-Marín
Global trade and travel is irreversibly changing the distribution of species around the world. Because introduced species experience drastic demographic events during colonisation, and often face novel environmental challenges from their native range, introduced populations may undergo rapid evolutionary change. Genomic studies provide the opportunity to investigate the extent to which demographic, historical, and selective processes shape the genomic structure of introduced populations by analysing the signature that these processes leave on genomic variation. Here...

Data from: Association between inbreeding depression and floral traits in a generalist-pollinated plant

Mohamed Abdelaziz, Antonio Jesús Muñoz-Pajares, Modesto Berbel, Francisco Perfectti & José María Gómez
Individual variation in the magnitude of inbreeding depression (ID) in plants and its association with phenotypic traits may have important consequences for mating system evolution. This association has been investigated only scarcely, and always considering traits functionally related to autogamy. Here, we explore the association between individual variation in ID and plant traits associated with pollinator attractiveness (related to plant size, corolla size and corolla shape) in two populations of Erysimum mediohispanicum (Brassicaceae). ID was...

Data from: Genetic inactivation of European sea bass (Dicentrarchus labrax L.) eggs using UV-irradiation: observations and perspectives

Androgenesis is a form of uniparental reproduction leading to progenies inheriting only the paternal set of chromosomes. It has been achieved with variable success in a number of freshwater species and can be attained by artificial fertilization of genetically inactivated eggs following exposure to gamma (γ), X-ray or UV irradiation (haploid androgenesis) and by restoration of diploidy by suppression of mitosis using a pressure or thermal shock. The conditions for the genetic inactivation of the...

Data from: City life makes females fussy: sex differences in habitat use of temperate bats in urban areas

Paul R. Lintott, Nils Bunnefeld, Elisa Fuentes-Montemayor, Jeroen Minderman, Rebekah J. Mayhew, Lena Olley, Kirsty J. Park, P. R. Lintott, N. Bunnefeld, E. Fuentes-Montemayor, R. J. Mayhew, J. Minderman, L. Olley & K. J. Park
Urbanization is a major driver of the global loss of biodiversity; to mitigate its adverse effects, it is essential to understand what drives species' patterns of habitat use within the urban matrix. While many animal species are known to exhibit sex differences in habitat use, adaptability to the urban landscape is commonly examined at the species level, without consideration of intraspecific differences. The high energetic demands of pregnancy and lactation in female mammals can lead...

Data from: Immune response costs are associated with changes in resource acquisition and not resource reallocation

Sumayia Bashir-Tanoli & Matthew C. Tinsley
1. Evolutionary ecologists frequently argue that parasite defence is costly because resources must be reallocated from other life-history traits to fuel the immune response. However, this hypothesis is rarely explicitly tested. An alternative possibility is that immune responses impair an organism's ability to acquire the resources it needs to support metabolism. Here, we disentangle these opposing hypotheses for why the activation costs of parasite resistance arise. 2. We studied fecundity costs associated with immune stimulation...

Data from: A seascape genetic analysis reveals strong biogeographical structuring driven by contrasting processes in the polyploid saltmarsh species Puccinellia maritima and Triglochin maritima.

Romuald Rouger, Alistair S. Jump, R. Rouger & A. S. Jump
Little is known about the processes shaping population structure in saltmarshes. It is expected that the sea should act as a powerful agent of dispersal. Yet, in contrast, import of external propagules into a saltmarsh is thought to be small. To determine the level of connectivity between saltmarsh ecosystems at a macro-geographical scale, we characterised and compared the population structure of two polyploid saltmarsh species, Puccinellia maritima and Triglochin maritima based on a seascape genetics...
