The micromorphology of foliar trichomes of Hypoestes aristata var. aristata was studied using stereo, light and scanning microscopy (SEM). This genus belongs to the advanced angiosperm family Acanthaceae, for which few micromorphological leaf studies exist. Results revealed both glandular and non-glandular trichomes, the latter being more abundant on leaf veins, particularly on the abaxial surf...

We present an automated system that we have developed for estimation of the bioecological quality of soils using various image analysis methodologies. Its goal is to analyze soilsection images, extract features related to their micromorphology, and relate the visual features to various degrees of soil fertility inferred from biochemical characteristics of the soil. The image methodologies used ...

In this study, the micromorphology of vegetative and reproductive structures endemic Centaurea glaberrima Tausch subsp. divergens (Vis.) Hayek (Asteraceae), using scanning electron microscope (SEM), is presented for first time. Uniseriate whip-like non-glandular biseriate glandular trichomes are found on surface all aboveground parts (stem, leaves, peduncles, involucral bract). On adaxial leaf ...

A new species of the genus Orbiniella Day, 1954 (Polychaeta: Orbiniidae), collected during the BIOICE programme on sedimentary bottoms off Iceland, is described. Orbiniella petersenae sp. nov. is a shelf and slope species (107 to 1,915 m) chiefly characterized by having notopodial postchaetal papilla from first chaetiger, long crenulated capillary chaetae and several acicular chaetae on each pa...

soil data can be very significantly informative in archeological and anthropological studies. bam citadel (bc), as the largest and oldest earthen (non baked brick) monument of the world has been restored for several times, but no data have yet been available surrounding the materials employed in the restoration work. bam citadel (bc) was almost totally destroyed by the severe earthquake of dece...

The phylogenetic relationships of Mertensia (Boraginaceae), which comprises approximately 45 species in both Asia and North America, have been uncertain, and taxonomists have placed the genus in various tribes of subfamily Boraginoideae, with the most recent placements in Trigonotideae and Cynoglosseae. Our study applies molecular phylogenetic methods to test the monophyly and relationships of ...
