Errores conceptuales en el estudio del equilibrio químico : nuevas aportaciones relacionadas con la incorrecta aplicación del principio de Le Chatelier [PDF]

open access: yes, 1995
The limited usefulness of the Le Chatelier's principle and its vague and ambiguous formulation may be some of the sources of misconceptions in chemical equilibrium.

A Large Fraction of Soil Microbial Taxa Is Sensitive to Experimental Warming

open access: yesGlobal Change Biology, Volume 31, Issue 5, May 2025.
Our analysis revealed that mid‐term (> 5 years) warming experiments can reshape (increases or decreases) a substantial portion of microbial community in dryland and temperate‐boreal ecosystems. Microbial taxa belonging to the same phylum showed different responses to warming, suggesting that other factors, such as photosynthetic cover or fungal ...

The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project

open access: yesEcology and Evolution, Volume 7, Issue 1, Page 145-188, January 2017., 2017
The collation of biodiversity datasets with broad taxonomic, biogeographic, and spatial extents is necessary to understand historical declines and to project—and hopefully avert—future declines. We describe and make freely available a database of more than 3.2 million biodiversity measurements from 94 countries representing over 47,000 species ...

Metodología para la predicción del desplazamiento del equilibrio químico: el caso de la modificación de la composición del sistema a temperatura constante [PDF]

open access: yes, 2012
El tratamiento de las perturbaciones de un sistema en equilibrio y el sentido del desplazamiento hacia un nuevo equilibrio es una cuestión muy importante en los cursos de Química General y Fisicoquímica.

Cognitive ecology of surprise in predator–prey interactions

open access: yesFunctional Ecology, Volume 39, Issue 3, Page 664-680, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In this review, we relate theoretical work on the importance of surprise in cognition to empirical research relevant to surprise in predator–prey interactions. There have been multiple proposals as to how surprise should be defined and quantified in the context of ...

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

open access: yesFunctional 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.

Effects of increasing soil moisture on Antarctic desert microbial ecosystems

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Overgeneralization and a lack of baseline data for microorganisms in high‐latitude environments have restricted the understanding of the microbial response to climate change, which is needed to establish Antarctic conservation frameworks. To bridge this gap, we examined over 17,000 sequence variants of bacteria and microeukarya across the ...
