    The pace of biodiversity change in a warming climate

    NEWS AND VIEWS 08 April 2020 The timing of disruptions to biodiversity associated with global warming is a key, but little-explored, dimension of change. Will losses in biodiversity occur all at once, or be spread out over time? Jennifer M. Sunday Jennifer M. Sunday is in the Department of Biology, McGill University, Montreal, Quebec H3A […] More

    Stable isotopes reveal the importance of seabirds and marine foods in the diet of St Kilda field mice

    Study area Samples were collected from live trapped St Kilda mice, at Carn Mor, Glen Bay, Village Bay (Fig. 1). Trapping locations were geographically distinct from one another (i.e. they were separated by escarpments or habitat unsuitable for mice to occupy) and were representative of the area of the island in which they were placed. At […] More

    Mature forest shows little increase in carbon uptake in a CO2-enriched atmosphere

    NEWS AND VIEWS 08 April 2020 Will mature forests absorb enough carbon from the atmosphere to mitigate climate change as levels of carbon dioxide increase? An experiment in a eucalyptus forest provides fresh evidence. Yiqi Luo & Yiqi Luo is at the Center for Ecosystem Science and Society, Department of Biological Sciences, Northern Arizona University, […] More

    Probabilistic modeling to estimate jellyfish ecophysiological properties and size distributions

    Conceptual model To understand the role played by jellyfish for carbon cycling, it is essential to trace each physiological process where carbon is implicated. An ecophysiological 0-D model was built based on three forcing variables, which are temperature (T), food concentration (F) and initial jellyfish carbon mass (CM). The growth (G; gC.d−1) of any organism […] More
