Ecological Characteristic of Calanoids (Copepoda, Calanoida) of the Inland Waters of Ukraine

Ecological Characteristic of Calanoids (Copepoda, Calanoida) of the Inland Waters of Ukraine

The article presents analyze of known published data and own observations on ecology of freshwater and brackish calanoid copepods of fauna of Ukraine. The briefly characteristic of main types of waterbodies inhabited by calanoids is given. The relation of species to the important ecological factors of water environment like temperature, habitat permanence, salinity, pH, current, suspended matters, and interaction with other hydrobionts is analyzed.

Essential Oil Composition of Three Species of Thymus Growing Wild in Mazandaran, Iran

Abstract

The genus Thymus has a wide distributional range and chemical composition of the essential oils varies with geographical location of collection site, climate and other ecological factors. The essential oils of the aerial parts were obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). Twenty seven components were characterized in the essential oil of T. fedtschenkoi. The major constituents of the oil were carvacrol (69.04%), thymol (5.95%), borneol (5.21%), p-cymene (4.20%), bornyl acetate (2.97%) and 1,8- cineole (2.72%). Twenty two components were characterized in the essential oil of T. trauveterri. The major constituents of the oil were carvacrol (54.02%), thymol (9.29%), borneol (3.51%), p-cymene (18.64%) and γ- terpinene (2.97%). Twenty six components were characterized in the essential oil of T. pubescens. The major constituents of the oil were carvacrol (13.85%), α-terpineol (11.49%), thymol (10%), geraniol (9.48%), α-pinene (8.52%), p-cymene (7.66%), camphor (4.66%), γ-terpinene (3.15%) and myrcene (2.22%). Twenty four components were characterized in the essential oil of T. fallax. The major constituents of the oil were carvacrol (41.84%), p-cymene (12.18%), α-terpineol (11.49%), thymol (10%), γ-terpinene (8.68%), borneol (5.11%), geraniol (4.35%) and geranyl acetate (2.16%).
