Disentangling direct from indirect effects of habitat disturbance on multiple components of biodiversity

Journal of Animal Ecology, Volume 91, Issue 11, Page 2220-2234, November 2022., 2022
Given that anthropogenic disturbance is one of the most important factors influencing ecological communities, a better understanding of the reciprocity of the various components of biodiversity is needed to predict the development of disturbed natural communities.

A meta‐analysis of tropical land‐use change effects on the soil microbiome: Emerging patterns and knowledge gaps

Biotropica, Volume 53, Issue 3, Page 738-752, May 2021., 2021
We identified 83 published paired studies that reported data on microbial biomass, abundance, composition, and enzyme activity under representative land‐use changes in the tropics. We found that microbial biomass, abundance, and functions were affected by land‐use change.

Darwin y la enorme diversidad microbiana

Ambiociencias, 2018
En los años en que Darwin desarrolló sus ideas, era poco lo que se sabía de los microorganismos. Darwin conocía de su existencia y los trabajos que estaban haciendo otros científicos. A pesar de todo, es fácil imaginar que en su época no había gran interés en explorar la diversidad microbiana, las plantas, los animales y los hongos constituyeron la ...

Conversion of Andean montane forests into plantations: Effects on soil characteristics, microorganisms, and microarthropods

Biotropica, Volume 52, Issue 6, Page 1142-1154, November 2020., 2020
Abstract Tropical montane forests in the Andes are subjected to deforestation and subsequent transformation into pastures. Abandoned pastures are frequently reforested by planting monoculture timber plantations, resulting in reduced aboveground diversity and changes in soil characteristics compared to primary forests.

Inhibition of biofilm bacteria and adherent fungi from marine plankton cultures using an antimicrobial combination

International Aquatic Research, 2018
The presence of organic matter in plankton cultures will lead to 10- to 1000-fold increases in bacterial density in less than 24 h. The presence of bacteria and fungi can damage cultivated phytoplankton and zooplankton.
