Climatic changes can result in modified leaf anatomy and gas exchange in arctic plants. In a one-year-old field experiment in Greenland Schollert et al. investigate the effects of increased snow depth and warming on leaf anatomy biogenic volatile organic compound (BVOC) emissions and CO2 exchange for the common arctic shrubs Betula nana and Empetrum nigrum ssp. hermaphroditum.  Light microscopy image of a cross-section of an Empetrum hermaphroditum leaf with glandular trichome (circle) and…

A recent spate of books  e.g. Daniel Chamovitzs What a plant knows Richard Karbans Plant Sensing & Communication and Brilliant Green by Stefano Mancuso and Alessandra Viola  have opened up our imaginations to the sensory capabilities of plants. In identifying plant equivalents of the five traditionally recognised human senses  touch taste hearing smell and sight  those volumes challenge us to re-examine the ways in which plants find out about their environments. However and as uncomfortable…

Leaf surface stomata from (Arabidopsis).  Stomata (plural of stoma) are tiny openings in the epidermis of a plant that are surrounded by pairs of crescent-shaped cells called guard cells that facilitate gas exchange.  Arabidopsis is an American weed used in many botanical genetic studies due to its short life cycle. SEM X240.
