Virtual plants: new perspectives for ecologists, pathologists and agricultural scientists
A new phase is under way in the study of how plants interact with their physical and biotic environments. Tools are becoming available for handling three−dimensional (3−D) information on the development and growth of individual plants and activities of the organisms which live on them. These tools will lead to in−depth understanding at the level of plant architecture, intermediate between what ...
متن کاملAlien plants in checklists and floras: towards better communication between taxonomists and ecologists
Invasion ecology is one of the most rapidly developing branches of ecology (Williamson, 1996; Rejmánek & al., in press). Recent developments in this field have brought about the need to standardize terminology (Richardson & al., 2000). The awareness of the importance of biological invasions dates back to De Candolle (1855) and Darwin (1859), but the field was set on firm ground in the middle of...
متن کاملEpigenetics for ecologists.
There is now mounting evidence that heritable variation in ecologically relevant traits can be generated through a suite of epigenetic mechanisms, even in the absence of genetic variation. Moreover, recent studies indicate that epigenetic variation in natural populations can be independent from genetic variation, and that in some cases environmentally induced epigenetic changes may be inherited...
متن کاملDNA barcoding for ecologists.
DNA barcoding - taxon identification using a standardized DNA region - has received much attention recently, and is being further developed through an international initiative. We anticipate that DNA barcoding techniques will be increasingly used by ecologists. They will be able to not only identify a single species from a specimen or an organism's remains but also determine the species composi...
متن کاملWhy plants grow poorly on very acid soils: are ecologists missing the obvious?
Factors associated with soil acidity are considered to be limiting for plants in many parts of the world. This work was undertaken to investigate the role of the toxicity of hydrogen (H(+)) which seems to have been underconsidered by ecologists as an explanation of the reduced plant growth observed in very acid soils. Racial differences are reported in plant growth response to increasing acidit...
