The Earth's surface temperature has risen by about 0.8 K over 3 the last 100 years partly due to human activities. If not for the poorly un-4 derstood radiative effects of aerosols, one would have been able to better use 5 the observed warming to constrain the all-important transient climate re-6 sponse (TCR, the pace of the warming caused by a continuous buildup of 7 greenhouse gases). Here we...
Sociality can be associated with significant costs due to the increased risk of disease transmission. However, in some organisms the costs may be offset by benefits due to improvements in defences against parasites. To examine this possible trade-off between infection risk and disease resistance, we used Acromyrmex leaf-cutting ants and the entomopathogenic fungus Metarhizium anisopliae as the ...
BACKGROUND AND AIMS Changes in number of trichomes and in composition and concentrations of their exudates throughout leaf development may have important consequences for plant adaptation to abiotic and biotic factors. In the present study, seasonal changes in leaf trichomes and epicuticular flavonoid aglycones in three Finnish birch taxa (Betula pendula, B. pubescens ssp. pubescens, and B. pub...
