The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

Limnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.

Water‐saving strategies in rice farming entail cascading effects in prey–predator interactions across ecosystem boundaries

Journal of Applied Ecology, Volume 62, Issue 9, Page 2273-2282, September 2025.
These results show that introducing multiple drainage periods in rice fields (i.e. AWD) indirectly hampers terrestrial spider reproduction through limiting the emergence of potential preys from the aquatic to terrestrial boundaries. MSD resulted in a more conciliatory strategy as it largely reduces methane emissions and does not affect predator–prey ...

¿Contribuye la ganadería bovina de Costa Rica al incremento del metano atmosférico y al calentamiento global?

Ciencias Ambientales, 2022
[Introducción]: El metano (CH4), al igual que otros gases que se han ido incrementando en la atmósfera, son responsables del efecto invernadero que deriva en el calentamiento global y el cambio climático.

Functional traits and soil water availability shape competitive interactions in a diploid–polyploid complex

Journal of Ecology, Volume 113, Issue 9, Page 2332-2345, September 2025.
Our study emphasises that the long‐term fate of polyploids largely depends on water availability, with high polyploids having a competitive advantage in arid environments. This ultimately highlights the role of functional traits in shaping the competitive dynamics between cytotypes.

Vegetative stage and soil horizon respectively determine direction and magnitude of rhizosphere priming effects in contrasting tree line soils

Functional Ecology, Volume 38, Issue 9, Page 1984-2002, September 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tree lines in high latitudes and high altitudes are considered sentinels of global change. This manifests in accelerated encroachment of trees and shrubs and enhanced plant productivity, with currently unknown implications for the carbon balance of these biomes.

Insect herbivory but not plant pathogen infection drive floral volatile‐mediated indirect effects on pollinators and plant fitness in Brassica rapa

Journal of Ecology, Volume 112, Issue 2, Page 402-415, February 2024.
Plants subjected to herbivory by the aphid Brevicoryne brassicae exhibited a marked reduction in the emission of two volatile organic compounds (nonanal and 2‐butyl‐1‐octanol), experienced lower pollinator visits and produced seeds of lower quality in terms of seed biomass and germination rate.

El impacto del cambio climático sobre la salud pública

Duazary, 2013
El actual cambio climático está ocurriendo como consecuencia de las actividades humanas, las cuales principalmente a través de la combustión de combustibles fósiles generan el dióxido de carbono (CO2), principal gas del efecto invernadero.

Los sistemas silvopastoriles y el calentamiento global: un balance de emisiones

Agronomía Costarricense, 2002
Se realizó un balance de emisiones de gases con efecto invernadero en Sistemas Silvopastoriles (SSP)ubicados en 3 diferentes zonas de vida. Se determinó la emisión de dióxido de carbono (CO2) y de óxido nitroso (N2O) en forma de gas, se cuantificó la ...

Las verdades más incómodas del cambio climático no son climáticas

Ecología Austral, 2015
El aumento de los gases de efecto invernadero (GEI) en la atmósfera es el más comentado —y uno de los más estudiados— de los impactos humanos sobre el planeta por ser motor del cambio climático y de su consecuencia más general y conocida: el ...
