Data from: Deleterious mutations show increasing negative effects with age in Drosophila melanogasterMartin Brengdahl, Christopher M. Kimber, Phoebe Elias, Josephine Thompson & Urban Friberg
Background In order for ageing to evolve in response to a declining strength of selection with age, a genetic architecture that allows for mutations with age-specific effects on organismal performance is required. Our understanding of how selective effects of individual mutations are distributed across ages is however poor. Established evolutionary theories assume that mutations causing ageing have negative late-life effects, coupled to either positive or neutral effects early in life. New theory now suggests evolution...
Natural history of model organisms: the secret (group) life of Drosophila melanogaster larvae and why it matters to developmental ecologyJuliano Morimoto & Zuzanna Pietras
Model organisms such as Drosophila melanogaster have been key tools for advancing our fundamental and applied knowledge in biological and biomedical sciences. However, model organisms have become intertwined with the idea of controlled and stable laboratory environments, and their natural history has been overlooked. In holometabolous insects, lack of natural history information on larval ecology has precluded major advances in the field of developmental ecology, especially in terms of manipulations of population density early in...
Strong foraging preferences for Ribes alpinum (Saxifragales: Grossulariaceae) in the polyphagous caterpillars of Buff tip moth Phalera bucephala (Lepidoptera: Notodontidae)Juliano Morimoto & Zuzanna Pietras
Herbivorous insects such as butterflies and moths are essential to natural and agricultural systems due to pollination and pest outbreaks. However, our knowledge of butterflies’ and moths’ nutrition is fragmented and limited to few common, charismatic, or problematic species. This gap precludes our complete understanding of herbivorous insects’ natural history, physiological and behavioural adaptations that drive how species interact with their environment, the consequences of habitat destruction and climate change to invertebrate biodiversity, and pest...
This is the data set used for the publication Buffering effects of soil seed banks on plant community composition in response to land use and climate, published in the journal Global Ecology and Biogeography. Aim. Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help...
We sequenced and assembled seven chromosomes of Aegilops comosa. The assembly with Meraculous resulted in ~ 50k - 186k scaffolds per chromosome with N50 size 6.4kb - 20.2kb. The scaffold sequences were used for development of molecular markers specific for cDNAs sequences mapped on Ae. comosa chromosomes Pairwise alignment of wheat cDNA-sequences and the chromosomal scaffolds of Ae. comosa identified candidate sequences. In order to analyze the structure and homeology of Aegilops chromosomes, forty-three mapped...
Animal studies have shown that maternal resource allocation can be sex-biased in order to maximize reproductive success, yet this basic concept has not been investigated in humans. In this study we explored the relationships between maternal factors, offspring sex and prenatal and postnatal weight gain. Sex-specific regression models not only indicated that maternal ethnicity impacted male (n = 2456) and female (n = 1871) childrens’ postnatal weight gain differently but also that parity and mode...
