However, although bark may confer some mechanical stability in woody plants, there is no evidence that the variability in bark thickness is the response to a selective force affecting stem stability. 2011), and when available, it often refers to some absolute values unrelated to diameter.

Thus, we confirm that fire can be a major driver of plant traits in fire-prone drylands. For a thin‐barked tree, selection for a thick bark occurs under recurrent low‐intensity fires, as high‐intensity fires kill all tree (a). 2010; Poorter et al. Funct Ecol 29:315–327. We examined bark thickness trends in trees and shrubs across a large-scale fire-rainfall gradient from desert to dry savanna in northern Australia. 2013). 3), there is a possibility that bark thickness could better explain global patterns of vegetation than leaf traits such as SLA (Wright et al. Please check your email for instructions on resetting your password. In addition, some species can accumulate large amounts of water in the stem, and in some cases, in the inner bark, and this explains some of the variability in bark thickness in species inhabiting arid fire‐free ecosystems (Rosell & Olson 2014). It is found in three middle-latitude regions with a temperate climate characterized by a winter season and year-round precipitation. Aust J Bot 57:396–405.

PubMed  However, these very low‐intensity fires may be of high severity for some very thin‐barked species and for young trees, and thus, the fires may kill some trees, opening up gaps that are filled with grasses.

Trees are naturally composed of logs blocks and leaves. Am J Bot 102:1590–1598. There are also fire regimes in which allocating resources to a thick bark is not adaptive (e.g. Unlike Oak Trees, these only come in one shape, so you won't need to worry about them growing in ways you don't expect. Mediterranean woodland description. Pairwise congeneric species comparisons showed a consistent relationship of thicker bark under high fire activity. Bark thickness is very variable among woody plants, and I hypothesize that fire is a key factor selecting for a thick bark, and thus, at the global scale, a significant proportion of the variability in bark thickness is explained by the variability in fire … For instance, resins are a key mechanism in conifers to protect from insect and fungus attacks (Berryman 1972; Phillips & Croteau 1999; Franceschi et al. In dry ecosystems with fuel discontinuities, fires are rare, very small, patchy or absent. Other bark properties, such as the amount of water, nutrients, lignins and deterring compounds, seem to be more important than bark thickness for large mammals (McNaughton 1988; Swanepoel 1993; Akashi & Nakashizuka 1999; Romero 2014). doi:10.1111/jvs.12171, Hoffmann WA, Franco AC (2008) The importance of evolutionary history in studies of plant physiological ecology: examples from cerrados and forests of central Brazil.

The fact that most tree species with thick bark are from warm environments (Table 1) and that the pine species with the thinnest bark are found in cold alpine environments (Keeley 2012) suggests that protection from cold is not a key driver of bark thickness; in general, boreal and tree line forest do not have tree with barks particularly thick. All of the above bushes grow flowers. Which biome with extreme temperature changes from day to night; it also has little plant life and, when there are plants, they must have deep roots or thick waxy leaves to prevent evaporation Taiga Which biome with long winter nights and long summer days; it has thin soil and is the largest biome. In contrast, the ecosystem were many species have thick bark in branches is the Brazilian cerrado, an ecosystem that suffers repetitive fires and most trees grow within the flame height. These low‐intensity fires, when frequent, select for thick bark. 2005), and latex, gums and the plethora of chemical compounds in the bark have a similar function in other plant groups (Agrawal & Konno 2009; Romero 2014). doi:10.1146/annurev.es.04.110173.000325, Orians GH, Milewski AV (2007) Ecology of Australia: the effects of nutrient-poor soils and intense fires. Ecosphere 2:art42. PubMed  biome. If there is another fire before the canopy closes to suppress the grasses, it spreads through the grass, and thus, this second fire is more intense and kills more trees. Consequently, there is a link between fire regime and bark thickness across ecosystems (Fig. chaparral- highly flammable resin. Am Nat 153:614–632, Knox KJE, Clarke PJ (2011) Fire severity and resource availability do not constrain resprouting ability in sclerophyll forests. PubMed Google Scholar. A nickname for the syndrome of plants living in frequent fire ecosystems is also included in, (a) Relationship between bark thickness (mm) and diameter (cm) for 53 tropical woody plants (from Dantas & Pausas, Boxplots of the relative bark thickness (RBT, i.e. doi:10.3732/ajb.1500157, Rosell JA, Olson ME (2014) The evolution of bark mechanics and storage across habitats in a clade of tropical trees. For trees, thicker bark (fire resistance) was strongly associated with epicormic resprouters. (2012) found that bark thickness together with other stem traits (wood density and bark moisture) explains post‐fire tree mortality in a transitional forests (from Amazonian forest to dry forests). Some grassland trees have thick bark to resist fire. However, there are other alternative hypotheses for developing a thick bark that need to be considered, such as to protect from harmful organisms, from extreme climates or to provide mechanical support (biotic, climatic and biomechanical hypotheses). Overall, these results suggest that, because bark fulfils many functions, in wet ecosystems where fires are absent, there may be no single function accounting for bark thickness variability. 2. doi:10.1890/140231, Griffin G (1989) Spinifex, fire and rain. That is, bark may reduce the damage of the tree by pests and herbivores, but in most cases, small variations in thickness provides little change in survival from damage by large mammals, and there is no clear evidence that at large scale, the distribution of thick‐barked trees reflects the distribution of a particular biotic interaction. water.
