Parallel functional differentiation of an invasive annual plant on two continents. [PDF]

open access: yes, 2019
Rapid local adaptation frequently occurs during the spread of invading species. It remains unclear, however, how consistent, and therefore potentially predictable, such patterns of local adaptation are.

Modifying Effect of the Antibiotic Action, Membrane Permeability, and ADMET/Toxicity Profile of the Fixed Oil From the Pulp of Mauritia Flexuosa F.L. (Arecaceae)

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT The increasing bacterial resistance to antibiotics has stimulated the search for natural products capable of modulating antimicrobial activity. In this study, the fixed oil from Mauritia flexuosa pulp was evaluated for its antibacterial activity, modulatory effect on antibiotics, membrane permeability, and ADMET/toxicity profile.

The Accessory Olfactory Bulb in Arvicola scherman: A Neuroanatomical Study in a Subterranean Mammal

open access: yesAnimals
The accessory olfactory bulb (AOB) processes chemical signals crucial for species-specific socio-sexual behaviors. There is limited information about the AOB of wild rodents, and this study aims to characterize the neurochemical organization of the AOB ...

SPrUCE: Utilizing Ultraconserved Elements of DNA for Population‐Level Genetic Diversity Estimation

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Ultraconserved elements (UCEs) provide ideal candidates for targeted sequencing and cost‐effective acquisition of genome‐wide data. While UCEs have been widely used in phylogenetic studies to reconstruct evolutionary relationships, their use in population‐level research has been limited.

Simple Harmonic Motion:Geometrical Solutions of Equations of Motions [PDF]

open access: yes, 2013
Conventionally while we talk about geometry associated with a simple harmonic oscillator, we draw a circle with a radius equal to the amplitude of Oscillator and imagine a particle moving along the perimeter with a frequency same as that of Oscillator ...

Cellular Hypertrophy and Increased Susceptibility to Spontaneous Calcium-Release of Rat Left Atrial Myocytes Due to Elevated Afterload [PDF]

open access: yes, 2015
Atrial remodeling due to elevated arterial pressure predisposes the heart to atrial fibrillation (AF). Although abnormal sarcoplasmic reticulum (SR) function has been associated with AF, there is little information on the effects of elevated afterload on

Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...
