why is tree bark thin in the tropical rainforest?

Oak trees have bark that grows four times faster than beech, which allows speedy repair and also helps to retain moisture, so oaks can survive in dry Mediterranean environments.

Why do rainforest trees have smooth thin bark? In the Caledonian Forest, some of the most obvious life on bark takes the form of lichens and small plants. Removing this tendency, we find a significant trend for species from more disturbed habitats to possess thicker bark. Tropical rainforest gaps and tree species diversity. Most trees in these tropical regions have straight trunks with no branches or leaves until they reach the canopy layer. Scientists, NGOs, and many global leaders largely agree that the real crisis is a political one. Pellegrini and his colleagues looked at 572 tree species in regions across the globe. There are still some deciduous trees such as maples and many mosses and ferns resulting in a Jurassic-looking forest. "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. Some species produce a high frequency of lenticels on the bark that facilitate gas exchange.

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). Most trees in tropical rainforests have thin, smooth bark. yearly rainfall ranges from 80 to 400 inches (200 to 1000 cm), and it can rain hard. Introduction.

The Kapok came from South America originally, but is now found in many rainforests around the world. Fish, reptiles, birds and insects also live in the rain forest and its rivers. Tropical forests of all varieties are disappearing rapidly as humans clear the natural landscape to make room for farms and pastures, to harvest timber for construction and fuel, and to build roads and urban areas.
