Soil carbon storage is related to tree functional composition in naturally regenerating tropical forests. [PDF]

Funct Ecol, 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Regenerating tropical forests are increasingly important for their role in the global carbon cycle. Carbon stocks in above‐ground biomass can recover to old‐growth forest levels within 60–100 years.

Nocturnal dissolved organic matter release by turf algae and its role in the microbialization of reefs. [PDF]

Funct Ecol, 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract The increased release of dissolved organic matter (DOM) by algae has been associated with the fast but inefficient growth of opportunistic microbial pathogens and the ongoing degradation of coral reefs.

Climatic and Edaphic Drivers of Soil Organic Carbon and Pyrogenic Carbon Stocks Across Elevation and Disturbance Gradients in Colombian Andean Forests. [PDF]

Glob Chang Biol
This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia. [PDF]

Ecol Evol
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

Seedling growth declines in warmed tropical forest soils

Biotropica, Volume 55, Issue 5, Page 897-910, September 2023., 2023
The response of tropical forest plants to a warming climate could have a large feedback on further climatic change. To address this, we tested the response of six tree species seedlings to 3 years of in‐situ experimental soil warming. Our study demonstrates that belowground warming causes species‐specific declines in the growth and photosynthesis of ...

On the relative importance of resource availability and habitat connectivity as drivers of soil biodiversity in Mediterranean ecosystems

Journal of Ecology, Volume 111, Issue 7, Page 1455-1467, July 2023., 2023
The authors provide a comprehensive assessment of the response of key members of the soil food web to habitat fragmentation and tree die‐off (landscape level plant–soil interactions), illustrating the major role of soil carbon, habitat connectivity, and tree die‐off in driving soil biodiversity and trophic structure.

Carbono orgânico no solo sob mata nativa e florestas plantadas em longo prazo

Pesquisa Florestal Brasileira, 2022
A matéria orgânica do solo (MOS) exerce papel fundamental para a sustentabilidade de ecossistemas florestais. O estudo das frações da MOS possibilita avaliar a qualidade do solo sob florestas nativas ou plantadas.

El carbono orgánico en Leptosols con distribución discontinua en la península de Yucatán/The organic carbon stock in Leptosls with discontinuous distribution in the Peninsula of Yucatan

Ecosistemas y Recursos Agropecuarios, 2017
Para determinar el contenido del carbono orgánico en el suelo (COS) se requiere cuanticar la fracción gruesa (piedras y gravas), la densidad aparente (DA) y profundidad. El inventario de suelos del INEGI no reporta estos datos, por lo que los mapas de

Desequilibrio del ciclo del azufre y cambio ambiental durante el Período Ediacárico

Estudios Geologicos, 2019
Se propone aquí un enfoque diferente para resolver el problema de las excursiones quimioestratigráficas negativas durante el Ediacárico, considerándolas en términos de un sistema vinculado de carbono-sulfuro-oxígeno, en el que los cambios en la dinámica ...

Cambios en las fracciones orgánicas resistentes en suelos de la región pampeana [PDF]

Ciencia del Suelo, 2020
Resumen Conocer la susceptibilidad a la degradación del material orgánico del suelo permite adecuar las prácticas de manejo en función de un mejor balance de carbono.
