Multitemporal Analysis of Land Cover Changes in the Rabanal Páramo Ecosystem (Colombia) From 2000 to 2020 and Its Planning Regulations

open access: yesLand Degradation &Development, Volume 36, Issue 7, Page 2247-2258, 30 April 2025.
ABSTRACT The páramos, with their high biodiversity and benefits to humanity, are crucial ecosystems in Colombia. Despite their importance, there is a significant knowledge gap regarding the extent of land cover changes and the identification of planning regulatory milestones on these ecosystems.

The Ribosomal Operon Database: A Full‐Length rDNA Operon Database Derived From Genome Assemblies

open access: yesMolecular Ecology Resources, Volume 25, Issue 1, January 2025.
ABSTRACT Current rDNA reference sequence databases are tailored towards shorter DNA markers, such as parts of the 16/18S marker or the internally transcribed spacer (ITS) region. However, due to advances in long‐read DNA sequencing technologies, longer stretches of the rDNA operon are increasingly used in environmental sequencing studies to increase ...

Leaf litter identity rather than diversity shapes microbial functions and microarthropod abundance in tropical montane rainforests

open access: yesEcology and Evolution, 2021
In tropical forest ecosystems leaf litter from a large variety of species enters the decomposer system, however, the impact of leaf litter diversity on the abundance and activity of soil organisms during decomposition is little known. We investigated the

Antimicrobial Polymeric Nanoparticles in Endodontics: A Systematic Review

open access: yesJournal of Nanotechnology, Volume 2025, Issue 1, 2025.
Background: The efficacy of endodontic treatments, essential for managing infections and injuries in dental pulp, heavily relies on completely eradicating microorganisms from the root canal system. Traditional methods often fail to achieve thorough disinfection, prompting the exploration of polymeric nanoparticles for their potential to enhance ...

Environmental conditions differently shape leaf, seed and seedling trait composition between and within elevations of tropical montane forests

open access: yesOikos, Volume 2024, Issue 11, November 2024.
The composition of plant functional traits varies in response to environmental conditions due to processes of community assembly and species sorting. However, there is a lack of understanding of how plant trait composition responds to environmental conditions at different spatial scales and across the plant life cycle.

Tracking climate vulnerability across spatial distribution and functional traits in Magnolia gentryi in the Peruvian tropical montane cloud forest

open access: yesAmerican Journal of Botany, Volume 111, Issue 9, September 2024.
Abstract Premise Understanding the responses of functional traits in tree species to climate variability is essential for predicting the future of tropical montane cloud forest (TMCF) tree species, especially in Andean montane environments where fog pockets act as moisture traps.
