In ecology, biotic and abiotic factors encompass all the living and non-living parts of an ecosystem. Biotic factors pertain to living organisms and their relationships. Abiotic factors are the ...

LifeTracer, a computational framework, was developed to analyze mass spectrometry data, identifying molecular features that distinguish abiotic from biotic origins. Georgia Tech and NASA used advanced ...

In this study, we investigate changes in ecosystem structure that occur over a gradient of land-degradation in the southwestern USA, where shrubs are encroaching into native grassland. We evaluate a ...

As climate change accelerates, the risk of sudden, large-scale shifts in ecosystems is growing. A new USGS study examines the mechanisms behind these abrupt ecological transformations—known as ...

Although a number of recent studies have demonstrated biotic homogenization, these have mainly focused on larger spatial scales. Homogenizing effects are equally important at finer resolutions, e.g.
