    Accelerating invasion potential of disease vector Aedes aegypti under climate change

    Study species Aedes aegypti is the primary vector for several important viruses of global health concern, including dengue, zika, yellow fever and chikungunya. Previous studies have suggested that climate change may have already influenced or will influence the distribution of suitable environments in which Ae. aegypti can thrive, resulting in changes in disease risk50,66. Beyond its […] More

    Skillful multiyear predictions of ocean acidification in the California Current System

    Model simulations The Community Earth System Model Decadal Prediction Large Ensemble22 (CESM-DPLE) is based on CESM, version 1.1, and uses the same code base, component model configurations (Supplementary Table 2), and historical and projected radiative forcing as that used in its counterpart, the CESM Large Ensemble24 (CESM-LE). This includes historical radiative forcing (with volcanic aerosols) through […] More

    Mutualism increases diversity, stability, and function of multiplex networks that integrate pollinators into food webs

    Network architecture We created multiplex networks (Fig. 2) by generating food webs using the “niche model” (Fig. 2a) parameterized with 50 species (Sf = 50) and 10% directed connectance (Cf = Lf/Sf2 = 0.1, where Lf is the number of feeding links)48. The niche model stochastically assigns each species i three traits: (1) a niche value (ni) drawn randomly from a uniform distribution […] More

    Will forests need vitamins?

    Atmospheric CO2 has increased from 350 to 410 ppm in the last three decades, which has been associated with greater plant growth and more efficient photosynthesis. The impacts of elevated CO2 on vegetation are, however, not all positive. Enhanced growth and photosynthesis can dilute nutrient concentrations in leaves, and plant physiological responses to elevated CO2 […] More
