Growing to 8 cm (3 in) tall by 30 cm (12 in) wide, it is a rosette -forming succulent perennial , valued in cultivation for its ability to colonise hot, dry areas ...
[4] [5] Each produce different enzymes, can degrade different plant materials, and can colonise different environmental niches. [6] Brown rot and soft rot both digest a tree's cellulose and hemicellulose but not its lignin; white rot digests lignin as well. The residual products of decomposition from fungal action have variable pH, solubility ...
Dimorphic – of two different forms. Ecad – a plant assumed to be adapted to a specific habitat. Ecotone – the boundary that separates two plant communities, generally of major rank – trees in woods and grasses in savanna for example. Ectogenesis – variation in plants due to conditions outside of the plants.
The three main early branches of the tree of life have been intensively studied by microbiologists because the first organisms were microorganisms. Microbiologists (led by Carl Woese) have introduced the term domain for the three main branches of this tree, where domain is a phylogenetic term similar in meaning to biological kingdom.
Epidermodysplasia verruciformis is different in that it leaves victims unable to fight off certain types of HPV. "Tree man" syndrome is so rare that only 200 cases have been reported globally.
