It also makes it difficult for epiphytes and plant parasites to get a hold on the trunks. Theory of 'smart' plants may explain the evolution of global ecosystems, More rain leads to fewer trees in the African savanna, Local plant-microbe alliances shape global biomes, Understanding animal coexistence with a little dung and a lot of DNA, Department of Ecology and Evolutionary Biology, National Oceanic and Atmospheric Association, Equal Opportunity Policy and Nondiscrimination Statement. tree bark adaptations. Bark minimizes water loss from the stems, deters insect and fungal attack, and can be a very effective protector against fire damage, as is demonstrated by the high fire resistance of redwood and giant sequoia trees, which have a massive bark. Rough, thick bark manages heat loss and moisture The Congo rainforest is the largest in Africa. In drier, temperate deciduous forests a thick bark helps to limit moisture evaporation from the tree's trunk. Tropical rainforests are so big that they are divided into four zones.

"We found large-scale evidence that bark thickness is a fire-tolerance trait, and we showed this is the case not just in a particular biome such as a savanna, but across different types of forests, across regions and across continents," said first author Adam Pellegrini, a NOAA Climate and Global Change Postdoctoral Fellow at Stanford University who led the study while a graduate student in Princeton's Department of Ecology and Evolutionary Biology. Young hazel has fairly smooth bark, and so attracts lichens that prefer this texture, particularly the script lichens. The more light the leaves receive, the higher the tree. Tightly packed trees grow quickly and to tremendous heights in humid, steamy rainforests. Deforestation not only removes trees that sequester greenhouse gases; it.

The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). The smoothness of the bark may also make it difficult for other plants to grow on their surface. However, people also rely on tropical rainforests for They semievergreen forest: longer dry season (the upper tree story consists of deciduous trees, while the lower story is still evergreen).
