Salt marsh structure and function, and consequently ability to support a range of species and to provide ecosystem services, may be affected by climate change. To better understand how salt marshes will respond to warming and associated shifts in precipitation, we conducted a manipulative experiment in a tidal salt marsh in Massachusetts, USA. We exposed two plant communities (one dominated by ...

BACKGROUND The aim of the present study was to appraise variation in the chemical composition, and antimicrobial and cytotoxic activities of essential oils from the leaves of four Mentha species-M. arvensis, M. piperita, M. longifolia and M. spicata-as affected by harvesting season. Disc diffusion and broth microdilution susceptibility assays were used to evaluate the antimicrobial activity of ...

Introduction: Thymbra spicata (T. spicata) is a conventional medicinal herb which is commonly used in the folklore medicine system of Iran. Aim of the study was to assess the antibacterial activity of the essential oil and hudroalcholic extract of the plant T. spicata on some important bacteria. Materials & methods: The essential oil and extract of T. spicata were obtained by hydrodistillation ...

Plants release volatile organic compounds (VOCs) that have many eco-physiological functions. Induction of plant VOCs is known to occur upon herbivory. Herbivore-induced VOCs are involved in the attraction of predators and parasitoids, a phenomenon known as an indirect defense of plants. We measured the VOC profiles of the wild species Veronica spicata with and without larval feeding and oviposi...

This paper reports detailed FISH-based karyotypes for three diploid wheatgrass species Agropyron cristatum (L.) Beauv., Thinopyrum bessarabicum (Savul.&Rayss) A. Löve, Pseudoroegneria spicata (Pursh) A. Löve, the supposed ancestors of hexaploid Thinopyrum intermedium (Host) Barkworth & D.R.Dewey, compiled using DNA repeats and comparative genome analysis based on COS markers. Fluorescence in si...

Green silver nanoparticles (AgNPs) and crude ethanolic, methanolic, aqueous, acetonic extracts from leaves of Agave americana, Mentha spicata, Mangifera indica were scrutinized for possible antineoplastic cytotoxic efficacy. In this study, all the synthesized AgNPs characterized using UV-Vis spectroscopy, X-ray diffraction, SEM (scanning electron microscopy), TEM (transmission EDX-spectroscopy,...

in traditional medicine, mentha spicata is widely used for many diseases, especially in  digestive system. it has anti-androgenic effects thus can be used by women experiencing polycystic ovary syndrome (pcos). also, it has shown to possess antioxidant properties. although beneficial, studies have shown its detrimental effect on some tissues. the present study was carried out to determine the e...

The present study was conducted with the objective of finding out the concordance between morphological data and molecular data of Mentha spicata and Mentha royleana. Moreover the study was aimed to investigate the relationship between and within the two species. Mentha species were collected from QAU, Shadara, Chattar, Donga gali and Qarshi industries, Hattar. For molecular study Random Amplif...
