Hace 1 día · Abstract. Human activities and climate change have accelerated species losses and degradation of ecosystems to unprecedented levels. Both theoretical and empirical evidence suggest that extinction cascades contribute substantially to global species loss. The effects of extinction cascades can ripple across levels of ecological organization ...

Hace 3 días · Boreal forests are major carbon sinks, but tree growth and soil carbon sequestration are limited by nutrient availability. Here, we tested whether long-term nutrient additions affect carbon storage i...
Hace 4 días · To strengthen the experimental evidence for the possible ecological consequences of global change, we systematically reviewed the literature on global change experiments in mountains. We first investigated the spread of manipulation experiments to test the effects of different global change drivers on key biological and ecological processes from the organism to the ecosystem level.
Hace 5 días · Nitrous oxide (N2O) is one of the most important climate-forcing gases, and a large portion of global anthropogenic N2O emissions come from agricultural soils. Yet, how contrasting global change factors and agricultural management can interact to drive N2O emissions remains poorly understood. Here, conducted within a rice–wheat cropping system, we combined a two-year field experiment with ...
Hace 1 día · Hence, we conclude that the change in “sensitivity” as given by the regression slope of two highly integrated metrics such as global AGR and annual mean tropical temperature does not reflect the local ecosystem response to the direct drivers (36, 38, 39, 60) nor does it imply a mechanistic change in global carbon cycle sensitivity to climate, as suggested, e.g., in .
Hace 5 días · From a sociometabolic perspective, globalization is not in decline. Recently, however, global growth has coincided with new patterns in income-based country groupings, which this article details. But even as these patterns change, material and energy use remain globalized.
