Article Synopsis
- The study investigates plant species composition and diversity along an elevation gradient in the northwestern Himalayas, focusing on 18 sites ranging from 2200 to 3900 m.
- It employs methods like Renyi diversity profiles and non-metric multidimensional scaling to analyze variations in species diversity, revealing lower and mid-altitude sites had richer species diversity.
- Findings indicate significant changes in plant species composition with altitude, highlighting a decrease in herbaceous and tree richness while shrub richness displayed a bimodal pattern, enhancing understanding of Himalayan vegetation trends.
The present study was carried out on scanning electron microscopic-based palynological characterization of selected 20 Euphorbiaceae taxa. In this study, important pollen qualitative and quantitative features of selected Euphorbiaceae species such as polar diameter, equatorial diameter, P/E ratio, sculpturing of pollen, exine thickness, intine thickness, presence or absence of colpi and length of colpi, and pollen fertility were examined. Remarkable variations in these pollen characters had been observed among these species.

Both qualitative and quantitative measurements for the anatomical characters like epidermal cells, stomata, trichomes, and subsidiary cells on both abaxial(ab) and adaxial(ad) epidermis were recorded. Remarkable variations in these anatomical features had been observed among the studied Euphorbiaceae species.
