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

Ecology 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

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

Molecular 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 ...

Antimicrobial Polymeric Nanoparticles in Endodontics: A Systematic Review

Journal 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 ...

Chloroplast microsatellites: measures of genetic diversity and the effect of homoplasy [PDF]

, 2005
Chloroplast microsatellites have been widely used in population genetic studies of conifers in recent years. However, their haplotype configurations suggest that they could have high levels of homoplasy, thus limiting the power of these molecular markers.

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

Oikos, 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.
