Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests. [PDF]

New Phytol
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

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 ...

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.

Climate and microhabitat shape the prevalence of endozoochory in the seed rain of tropical montane forests

Biotropica, Volume 55, Issue 2, Page 408-417, March 2023., 2023
We investigated the effects of climate and microhabitat conditions on the prevalence of endozoochorous plant species in the seed rain of tropical montane forests in southern Ecuador. Our analyses demonstrate that the prevalence of endozoochorous plant species in seed rain increases with temperature across elevations and with leaf area index within ...

Influencia del efecto de la humedad del suelo en la emisividad del infrarrojo térmico [PDF]

, 2007
La influencia del efecto de la humedad del suelo en la emisividad del infrarrojo térmico es un hecho conocido pero poco estudiado en el pasado. Se ha diseñado un experimento para calcular la dependencia de la emisividad respecto a la humedad del suelo ...

Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse

Conservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

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.

Patterns and controls on island‐wide aboveground biomass accumulation in second‐growth forests of Puerto Rico

Biotropica, Volume 54, Issue 5, Page 1146-1159, September 2022., 2022
Understanding the heterogeneity of biomass accumulation in second‐growth tropical forests following land use abandonment is important for informing ecosystem carbon models and forest restoration efforts. Using airborne lidar data, we quantify patterns and controls on aboveground biomass accumulation in second‐growth forests of Puerto Rico.

Modelling habitat suitability for a potential flagship species, the hooded capuchin, of the Paraguayan Upper Paraná Atlantic Forest

Ecological Solutions and Evidence, Volume 3, Issue 3, July–September 2022., 2022
The hooded capuchin in the Paraguayan Upper Paraná Atlantic Forest is a forest obligate species and avoids crop fields. The monkeys are less likely to be found in degraded areas even if they are still forested. As Paraguayan deforestation involves the creation of large crop fields separating BAAPA fragments, the probability that the hooded capuchin can
