Data from: Body reserves mediate trade-offs between life history traits: new insights from small pelagic fish reproduction

Limited resources in the environment prevent individuals from simultaneously maximizing all life-history traits, resulting in trade-offs. In particular, the cost of reproduction is well known to negatively affect energy investment in growth and maintenance. Here, we investigated these trade-offs during contrasting periods of high versus low fish size and body condition (before/after 2008) in the Gulf of Lions. Female reproductive allocation and performance in anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) were examined based on...

Data from: An experimental comparison of three Towed Underwater Video Systems using species metrics, benthic impact and performance

1. Managing ecological systems, which operate over large spatial scales is inherently difficult and often requires sourcing data from different countries and organizations. The assumption might be made that data collected using similar methodologies are comparable but this is rarely tested. Here, benthic video data recorded using different towed underwater video systems (TUVSs) were experimentally compared. 2. Three technically different TUVSs were compared on different seabed types (rocky, mixed ground and sandy) in Kingmere Marine...

Data from: Kin effects on energy allocation in group-living ground squirrels

Vincent A. Viblanc, Claire Saraux, Jan O. Murie & F. Stephen Dobson
The social environment has potent effects on individual phenotype and fitness in group-living species. We asked whether the presence of kin might act on energy allocation, a central aspect of life-history variation. Using a 22-year data set on reproductive and somatic allocations in Columbian ground squirrels (Urocitellus columbianus), we tested the effects of co-breeding and non-breeding kin on the fitness and energy allocation balance between reproduction and personal body condition of individual females. Greater numbers...

Data from: Genetic diversity of oilseed rape fields and feral populations in the context of coexistence with GM crops

Diane Bailleul, Sébastien Ollier & Jane Lecomte
Despite growing concern about transgenes escaping from fields, few studies have analysed the genetic diversity of crops in an agroecosystem over several years. Accurate information about the dynamics and relationship of the genetic diversity of crops in an agroecosystem is essential for risk assessment and policies concerning the containment of genetically modified crops and their coexistence with crops grown by conventional practices. Here, we analysed the genetic diversity of oilseed rape plants from fields and...

Data from: RClone: a package to identify MultiLocus Clonal Lineages and handle clonal datasets in R

Diane Bailleul, Solenn Stoeckel & Sophie Arnaud-Haond
Partially clonal species are common in the Tree of Life. And yet, population genetics models still mostly focus on the extremes: strictly sexual versus purely asexual reproduction. Here we present an R package built upon GenClone software including new functions and several improvements. The RClone package includes functions to handle clonal datasets, allowing (i) checking for dataset reliability to discriminate multi-locus genotypes (MLG), (ii) ascertainment of MLG and semi-automatic determination of clonal lineages (MLL), (iii)...
