Interactions between the atmosphere, biosphere, cryosphere, hydrosphere, and geosphere
are most active in the critical zone, a region extending from the tops of trees to the top of …

Although the burrowing activity of some species (eg gophers) is well studied, a
comprehensive inventory of burrowing animals in adjacent biomes is not yet known, despite …

Abstract The Chilean Coastal Cordillera features a spectacular climate and vegetation
gradient, ranging from arid and unvegetated areas in the north to humid and forested areas …

Vegetation influences erosion by stabilizing hillslopes and accelerating weathering, thereby
providing a link between the biosphere and Earth's surface. Previous studies investigating …

Weathering and ecosystem nutrition are intimately linked through the supply of fresh mineral
nutrients from regolith and bedrock (the “geogenic nutrient pathway”). However, the …

Low-molecular-weight organic acids (LMWOAs) are crucial for the mobilization and
acquisition of mineral phosphorus by plants. However, the role of LMWOAs in mobilizing …

Comparing the belowground allocation of assimilated carbon (C) to roots and mycorrhizal
fungi across biomes can reveal specific plant nutrient acquisition strategies in ecosystems …

Along the coast of the hyperarid Atacama Desert, late Quaternary alluvial fans emerge from
the Coastal Cordillera to the Pacific Ocean between 20.5° S and 25.5° S. Coastal alluvial …

Critical Zone Science (CZS) represents a powerful confluence of research agendas, tools,
and techniques for examining the complex interactions between biotic and abiotic factors …

Plants and their associated below-ground microbiota possess the tools for rock weathering.
Yet the quantitative evaluation of the impact of these biogenic weathering drivers relative to …
