    Purging of highly deleterious mutations through severe bottlenecks in Alpine ibex

    Genomic data acquisition DNA samples from 29 Alpine ibex, 4 Iberian ibex, 2 Nubian ibex, 2 Siberian ibex and 1 Markhor individuals were sequenced on an Illumina Hiseq2500 or Hiseq4000 to a depth of 15–38 (median of 17). Supplementary Table 2 specifies individual sampling locations. Libraries were produced using the TruSeq DNA Nano kit. Illumina sequencing […] More

    Global distribution patterns and niche modelling of the invasive Kalanchoe × houghtonii (Crassulaceae)

    Global occurrences: standard sources vs. citizen science Using exclusively “standard” sources including biodiversity web portals, herbaria, scientific publications, personal observations, and personal communications to search for documented locations would lead to large distributional biases. Indeed, using exclusively standard sources would imply that more than one third of them would be lost. Our results emphasize the […] More

    Sustainability of spatially distributed bacteria-phage systems

    A typical set of mass action equations for the bacterial density B, the density of free phages P, and the nutrient n take the form13,14,23,35: $$begin{array}{l}frac{dn}{dt}=-lambda Bfrac{n}{n+K} frac{dB}{dt}=lambda Bfrac{n}{n+K}-eta BP frac{dP}{dt}=(beta -1)eta BP-delta Pend{array}$$ (1) where the nutrient n is measured in units of bacteria it can be converted to (corresponding to a yield of […] More

    Resource use by individual Drosophila suzukii reveals a flexible preference for oviposition into healthy fruits

    The D. suzukii population used in this study originated from ~50 flies that emerged from elderberries collected in September 2016 in northern Germany. Since then the flies had been kept at a population size of approx. 200 flies in custom-made population cages (22 litres). For egg collection, flies were offered thawed raspberries, and oviposited fruits were […] More

    Complementary molecular methods reveal comprehensive phylogenetic diversity integrating inconspicuous lineages of early-diverged wood-decaying mushrooms

    Study site and sample collection The study site was a mixed forest of P. densiflora, a coniferous tree, and broad-leaved deciduous trees at an elevation of ~1,300 m in the Sugadaira Research Station (N36°31′17″, E138°20′60″), University of Tsukuba. According to the Japan Meteorological Agency, statistical data for 1981−2010, the average annual temperature of this area is […] More

    Migration, hotspots, and dispersal of HIV infection in Rakai, Uganda

    Cross-community migration is pervasive in rural Uganda Rakai District is a predominantly rural district in south-central Uganda (area ~2200 km2, population ~518,000) bordered by Masaka District to the north, Tanzania to the south, and Lake Victoria to the east. The Rakai Community Cohort Study (RCCS) is an open population-based household census and cohort of adults aged […] More

    Caretta caretta nesting activity on Akumal Beaches, Mexico

    What do the numbers show The Cc females that were observed in Akumal were increasingly frequent but decreased in size in the last years of the conservation programme. It is probable that many Cc born on Akumal beaches were recruited to nest, showing philopatric behaviour. The results show that the Cc nesting in Akumal deposited […] More
