N and P constrain C in ecosystems under climate change: Role of nutrient redistribution, accumulation, and stoichiometry

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract We use the Multiple Element Limitation (MEL) model to examine responses of 12 ecosystems to elevated carbon dioxide (CO2), warming, and 20% decreases or increases in precipitation. Ecosystems respond synergistically to elevated CO2, warming, and decreased precipitation combined because higher water‐use efficiency with elevated CO2 and higher ...

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta‐analysis in insects

open access: yesEvolution Letters, Volume 6, Issue 6, Page 394-411, December 2022., 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...
