Polyploidization is one of the leading forces in the evolution of land plants, providing opportunities for instant speciation and rapid gain of evolutionary novelties. Highly selective conditions of serpentine environments act as an important evolutionary trigger that can be involved in various speciation processes. Whereas the significance of both edaphic speciation on serpentine and polyploid...

A new species of eriophyoid mite, Aculus castriferrei n. sp., associated with Agrimonia eupatoria (Rosaceae) is described and illustrated from Hungary. Morphological differences distinguishing this vagrant species from other rosaceous inhabiting congeners are discussed. Aceria malherbae Nuzzaci is a new record for the eriophyoid fauna of Hungary after it was found causing severe damage symptoms...

INTRODUCTION Leaf extract of Mentha arvensis or mint plant was used as reducing agent for the synthesis of green silver nanoparticles (GSNPs) as a cost-effective, eco-friendly process compared to that of chemical synthesis. The existence of nanoparticles was characterized by ultraviolet-visible spectrophotometry, dynamic light scattering, Fourier transform infrared spectroscopy, X-ray diffracti...

This article examines the extent to which indicators of the college-going climate of urban high schools are associated with students’ application to, enrollment in, and choice among four-year colleges. The investigators examine two mechanisms by which high schools may shape college enrollment among low-income students in an urban school system: (1) by ensuring whether seniors who aspire to a fo...

The plant of Convolvulus pluricaulis Choisy was found to be used by different traditional systems and folklore for the treatment of various disorders. The aim of the present study was to investigate the neuropharmacological activity of various extracts of Convolvulus pluricaulis Choisy in albino mice. The animal behavior was evaluated by locomotor activity, tremors activity, sleep inducing mode...
