Subject:
biochemistry; climate; climate change; community structure; dry environmental conditions; ecosystems; protists; soil; soil biology; soil microorganisms; surveys; topology; uncertainty; water stress; Australia
Abstract:
... Protists are ubiquitous and abundant in soil and contribute to key ecosystem processes including nutrient cycling and top-down regulation of soil microbiome. Drought stress will change the protistan community composition and network stability, which introduces uncertainty to predict their functions under a changing climate. A field survey was conducted across >2000 km in contrasting interior land ...

For a long time, the prevailing expectation has been that thermal stability in deep ocean layers will delay ecosystem responses to warming. Few observational studies have challenged this view and indicated that deep organisms can respond exception ...
