LOS INCENDIOS FORESTALES AFECTAN LAS PROPIEDADES FÍSICAS DEL SUELO [PDF]

Revista Acta Ambiental Catarinense, 2023
El objetivo fue evaluar el efecto del fuego sobre las propiedades físicas de un suelo afectado por un incendio forestal en el cerro “Corumo”, Sierra de San Luís, Estado Falcón-Venezuela, siendo esta un área estratégica para la protección del ambiente y del Sistema Hidrológico “El Falconiano”. Fueron delimitadas tres áreas: a) Plantación Afectada por el

Indicadores de sostenibilidad agrícola asociados a propiedades, procesos y manejo del suelo

Ciencia y Tecnología Agropecuaria, 2021
Las evaluaciones de sostenibilidad son el mecanismo más adecuado para determinar si un método, alternativa o tendencia de producción de cultivos es viable desde el punto de vista ambiental, económico y social. Estas evaluaciones se realizan por medio de

Patterns of leaf trait variation underlie ecological differences among sympatric tree species of Damburneya in a tropical rainforest. [PDF]

Am J Bot, 2022
Abstract Premise Although ecological differentiation driven by altitude and soil is hypothesized to promote coexistence of sympatric tree species of Damburneya (Lauraceae), the mechanistic role of leaf functional variation on ecological differentiation among co‐occurring species remains unexplored.

The role of nutritional impairment in carbon-water balance of silver fir drought-induced dieback. [PDF]

Glob Chang Biol, 2022
Declining silver fir trees show lower foliar concentrations of essential nutrients such as P, K, Cu and Ni than non‐declining trees. This nutritional impairment exacerbates and amplifies the negative effects of drought on tree functioning and growth, considering the relationship of tree nutritional status with water‐use efficiency and growth resilience

Microbial drivers of root plasticity. [PDF]

New Phytol
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Strong scale-dependent relationships between fine-root function and soil properties uncovered with spatially coupled sampling. [PDF]

New Phytol
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Seasonality regulates the structure and biogeochemical impact of ectomycorrhizal fungal communities across environmentally divergent neotropical dry forests

Journal of Ecology, Volume 111, Issue 8, Page 1598-1613, August 2023., 2023
These results highlight the importance of seasonality and plant community composition in shaping different aspects of SDTF ECM fungal community structure and diversity as well as the potential for both the plant and fungal components of ECM symbioses to impact soil functioning across heterogenous SDTFs.

Trait functional diversity explains mixture effects on litter decomposition at the arid end of a climate gradient

Journal of Ecology, Volume 110, Issue 9, Page 2219-2231, September 2022., 2022
Litter mixing did not have strong effects on decomposition rates across the studied climatic gradient overall, and the direction and intensity of the mixture effects were context dependent. The effects were stronger and more negative in the dryer ecosystems.

Fires in the Amazon Region: Quick Policy Review

Development Policy Review, Volume 40, Issue 5, September 2022., 2022
Summary Motivation The combination of institutional weaknesses, climate change, and overexploitation is increasingly recognized as endangering the Amazon forest. These three factors made 2020 the worst year for forest fires recorded in the previous 60 years.

The above–belowground functional space of tropical dry forest communities responds to local hydric habitats

Biotropica, Volume 54, Issue 4, Page 1003-1014, July 2022., 2022
By comparing aboveground and belowground traits of saplings from two distinctive dry forest plant communities differing in water and light availability we found that in the wetter community traits related to the efficiency of resource capture were decoupled from the drought‐tolerance drought‐avoidance trade‐off thus developing more efficient fine roots.
