A five-story 168,000-square-foot (15,600 m 2) Chemistry Building opened on May 2, 2008. Also having worked in the field of materials science and nanoscience at FSU is the Nobel laureate Sir Harry Kroto, the co-discoverer of the C 60 "buckyball", who retired from FSU's Department of Chemistry and Biochemistry in 2015.

The shrub layer is the stratum of vegetation within a habitat with heights of about 1.5 to 5 metres. This layer consists mostly of young trees and bushes, and it may be divided into the first and second shrub layers (low and high bushes). The shrub layer needs sun and little moisture, unlike the moss layer which requires a lot of water.
Under woody encroachment, less meat and milk is produced per head of cattle, which challenges traditional pastoral diets. [139] [140] The management of bush encroachment is found to stabilize rangelands and contribute to food security. [124] Shrub encroachment in forest areas of Ethiopia, such as the Desa'a Forest, reduces carbon stocks. [141]
In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap.
Interior scrublands occur naturally in semi-arid areas with nutrient-poor soils, such as on the matas of Portugal, which are underlain by Cambrian and Silurian schists. Florida scrub is another example of interior scrublands. Dwarf shrubs Moorland on Kilimanjaro. Some vegetation types are formed of dwarf-shrubs, low-growing or creeping shrubs.
It has an unusually diverse tree flora, with as many as 30 tree species at a single site including many relics of the ancient forest that once covered North America more widely. Along with the forest there is a rich undergrowth of ferns , fungi , herbaceous plants , shrubs and small trees as well as areas of glade , heath , shale , peat bog and ...
The scientific use of life-form schemes emphasizes plant function in the ecosystem and that the same function or "adaptedness" to the environment may be achieved in a number of ways, i.e. plant species that are closely related phylogenetically may have widely different life-form, for example Adoxa moschatellina and Sambucus nigra are from the ...
Pinaceae that persist in areas where tree squirrels are abundant do not seem to have evolved adaptations for bird dispersal. Boreal conifers have many adaptions for winter. The narrow conical shape of northern conifers, and their downward-drooping limbs help them shed snow, and many of them seasonally alter their biochemistry to make them more ...
