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

open access: yesJournal 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.

CALIBRACIÓN DE SENSORES DE REFLECTOMETRÍA DE DOMINIO TEMPORAL EN SUELOS ULTISOLES DE SABANA

open access: yesAnales Científicos, 2022
El método de determinación del contenido de agua en el suelo a través de sondas TDR (Time Domain Reflectometry) estima el contenido de agua con base a la permisividad dieléctrica del suelo, utilizando un polinomio de tercer orden. Sin embargo, en algunas

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

open access: yesBiotropica, 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 ...

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

open access: yesConservation 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

open access: yesJournal 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

open access: yesBiotropica, 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.
