Endozoochory by slugs can increase bryophyte establishment and species richness
Herbivory can aff ect plant community composition and diversity by removing biomass and reducing light competition. Herbivory may particularly benefi t low growing species such as bryophytes, which are frequently limited by light competition. Gastropods are important herbivores of seed plants and cryptogams, furthermore, they can disperse propagules such as seeds and spores via endozoochory. Ho...
متن کاملLichen Endozoochory by Snails
Endozoochory plays a prominent role for the dispersal of seed plants. However, for most other plant taxa it is not known whether this mode of dispersal occurs at all. Among those other taxa, lichens as symbiotic associations of algae and fungi are peculiar as their successful dispersal requires movement of propagules that leaves the symbiosis functional. However, the potential for endozoochorou...
متن کاملArsenic Phytoextraction and Hyperaccumulation by Fern Species
Arsenic (As) is an ubiquitous trace metalloid found in all environmental media. Its presence at elevated concentrations in soils derives from both anthropogenic and natural inputs. Arsenic is a toxic and carcinogenic element, which has caused severe environmental and health problem worldwide. Technologies currently available for the remediation of arsenic-contaminated sites are expensive, envir...
متن کاملSpontaneous turning behaviour by Dictyostelium discoideum slugs.
Dictyostelium discoideum slugs migrating in the absence of external stimuli tend to continue migrating in the original randomly 'chosen' direction. Spontaneous deviations from the starting direction accumulate with time at a rate that measures the 'physiological noise' in the slugs' steering mechanism. Most of the spontaneous turning signals arise in the transduction chain 'downstream' of the c...
متن کاملFERNS AND FERN ALLIES OF IRAN
The pteridophyte account of Flora Iranica (ed. K.H. Rechinger) is still not published. The Caspian forests provide suitable habitats for the growth of many ferns and fern allies in Iran. In semi-arid and mountainous areas of Iran, mesophilous plants are restricted to rock crevices, waterfall proximity, stream banks and lake shores. Based on field collections and study of herbarium specimens in ...
