Seed Traps Differ in Species Numbers, Seed Densities and Contamination but Mostly Do Not Reflect Grazing in a Pampa Grassland

open access: yesApplied Vegetation Science, Volume 29, Issue 2, April/June 2026.
Ground traps are more effective than adhesive traps in measuring seed rain species richness and density. They also allow to more closely resemble the seed production of the surrounding vegetation. Management‐driven differences in the vegetation were not reflected by the seed rain of any trap type, but the advantages and disadvantages of different trap ...

Hydrogen peroxide in micropropagation of Lilium: A comparison with a traditional methodology [PDF]

open access: yes, 2006
The micropropagation of Lilium longiflorum requires adequate equipment which may not be afforded by small laboratories or producers. In this work we compared traditional methodology with a protocol that included easily available elements to sterilize ...

Progeny performance and pathogen attack relative to elevation in a neotropical tree [PDF]

open access: yes, 2019
Climate and resource availability at the parent tree location are known to explain progeny characteristics; however, few studies have examined the role of resistance or tolerance to pathogens, even though climate is a main driver of pathogen abundance ...

Imaging of Molecular and Developmental Responses to Abiotic Stresses in Reproductive Tissues

open access: yesPhysiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stresses, such as drought, salinity, and extreme temperatures, have profound effects on plant reproduction, often leading to reduced fertility and yield. Reproduction in plants involves complex interactions between diverse cells, necessitating spatiotemporal resolution to understand how stress impacts each component of this intricate ...

A Bioinformatics Approach for Detecting Repetitive Nested Motifs using Pattern Matching [PDF]

open access: yes, 2016
The identification of nested motifs in genomic sequences is a complex computational problem. The detection of these patterns is important to allow discovery of transposable element (TE) insertions, incomplete reverse transcripts, deletions, and/or ...

Enhanced Electroactivity for Overall Water Splitting and Oxygen Potential of Pt/Carbon Nanotubes Functionalized with Cu Organometallic Complex

open access: yesEnergy Technology, Volume 13, Issue 11, November 2025.
Functionalizing carbon nanotubes (CNT) with the mesitylcopper (Cu‐mes) complex modifies the surface of CNT, developing Cu‐Pt alloys and Cu‐species. The result is a modified Pt electronic structure that promotes the catalytic activity of the 5 wt% Pt/CNTCu‐mes nanocatalyst for hydrogen and oxygen evolution reactions, and oxygen reduction reaction.

Agrobacterium rhizogenes vs auxinic induction for in vitro rhizogenesis of Prosopis chilensis and Nothofagus alpina [PDF]

open access: yes, 2003
The induction and improvement of in vitro rhizogenesis of microshoots of Prosopis chilensis (Mol.) Stuntz and Nothofagus alpina (Poep. et Endl. Oerst.) were compared using Agrobacterium rhizogenes (Ar) versus indole-3-butyric acid (IBA) in the culture ...
