Data from: Chronic exposure to low-dose radiation at Chernobyl favours adaptation to oxidative stress in birds

1. Ionizing radiation produces oxidative stress, but organisms can adapt to their exposure with physiological adaptive responses. However, the role of radioadaptive responses in wild populations remains poorly known. 2. At Chernobyl, studies of birds and other taxa including humans show that chronic exposure to radiation depletes antioxidants and increases oxidative damage. Here we present analyses of levels of the most important intracellular antioxidant (i.e., glutathione, GSH), its redox status, DNA damage and body condition...

Data from: Flying the nest: male dispersal and multiple paternity enables extrafamilial matings for the invasive bark beetle Dendroctonus micans

Ceridwen I. Fraser, Olivier Brahy, Patrick Mardulyn, Loïc Dohet, François Mayer & Jean-Claude Grégoire
There is an evolutionary trade-off between the resources that a species invests in dispersal versus those invested in reproduction. For many insects, reproductive success in patchily-distributed species can be improved by sibling-mating. In many cases, such strategies correspond to sexual dimorphism, with males–whose reproductive activities can take place without dispersal–investing less energy in development of dispersive resources such as large body size and wings. This dimorphism is particularly likely when males have little or no...

Data from: Congruent phylogeographic patterns of eight tree species in Atlantic Central Africa provide insights on the past dynamics of forest cover

Gilles Dauby, Jérôme Duminil, Myriam Heuertz, K. Guillaume Koffi, Tariq Stévart & Olivier J. Hardy
Cycles of Quaternary climate change are assumed to be major drivers of African rainforest dynamics and evolution. However, most hypotheses on past vegetation dynamics relied on palaeobotanical records, an approach lacking spatial resolution, and on current patterns of species diversity and endemism, an approach confounding history and environmental determinism. In this context, a comparative phylogeographic study of rainforest species represents a complementary approach because Pleistocene climate fluctuations may have left interpretable signatures in the patterns...

Data from: Parental separation and behaviours that influence the health of infants aged 7 to 11 months: a cross-sectional study

Nadine Kacenelenbogen
Objective: Analyse the parental behaviours that are recognized as influencing the health of very young children based on family structure (parents separated or not). Design: Cross-sectional study, examining 79,701 infants aged 7 to 11 months as part of a free preventive medicine consultation. The data came from an assessment conducted 7 to 11 months after birth during which information was collected, namely about the parents' use of tobacco, the infant's type of nutrition, and adherence...

Data from: Determinants of maternal near misses in Morocco: too late, too far, too sloppy?

Bouchra Assarag, Bruno Dujardin, Alexandre Delamou, Fatima-Zahra Meski & Vincent De Brouwere
Background: In Morocco, there is little information on the circumstances surrounding maternal near misses. This study aimed to determine the incidence, characteristics, and determinants of maternal near misses in Morocco. Method:A prospective case-control study was conducted at 3 referral maternity hospitals in the Marrakech region of Morocco between February and July 2012. Near-miss cases included severe hemorrhage, hypertensive disorders, and prolonged obstructed labor. Three unmatched controls were selected for each near-miss case. Three categories of...
