Effects of Microplastics in Soil Ecosystems: Above and Below Ground.
Environmental Science and Technology, 2019 Environmental contamination by microplastics is now considered an emerging threat to biodiversity and ecosystem functioning. Soil ecosystems, particularly agricultural land, have been recognized as a major sink of microplastics, but the impacts of ...

Ecosystem Adaptation: Do Ecosystems Maximize Resilience? [PDF]
Ecology, 2002 The response of an ecological system to perturbation can be described in terms of its resilience, essentially a measure of the time the system takes to return to its prior state. The resilience of an ecosystem is the result of interactions of the biota and their environment and will therefore change as the biota evolve and environmental conditions ...

Targeting p38α in cancer: challenges, opportunities, and emerging strategies
Molecular Oncology, EarlyView.p38α normally regulates cellular stress responses and homeostasis and suppresses malignant transformation. In cancer, however, p38α is co‐opted to drive context‐dependent proliferation and dissemination. p38α also supports key functions in cells of the tumor microenvironment, including fibroblasts, myeloid cells, and T lymphocytes.

Arctic climate shifts drive rapid ecosystem responses across the West Greenland landscape
Environmental Research Letters, 2019 Prediction of high latitude response to climate change is hampered by poor understanding of the role of nonlinear changes in ecosystem forcing and response. While the effects of nonlinear climate change are often delayed or dampened by internal ecosystem

Nature Communications, 2020 Phosphorus (P) limitation of aboveground plant production is usually assumed to occur in tropical regions but rarely elsewhere. Here we report that such P limitation is more widespread and much stronger than previously estimated.
