Bursera schlechtendalii and Bursera biflora are representative of the squirting and non-squirting syndromes respectively. Related articles in Google Scholar. Close mobile search navigation Article navigation. The occurrence of complex mixtures of compounds, is a widespread phenomenon among plants that produce terpenoids and it has been associated with several factors Gershenzon and Croteau, Producing mixtures with more individual compounds requires production of more specific enzymes.

The squirt defense has detrimental effects even on these specialized vein-cutting herbivores. Squirt strength was ranked from 0 no release to 3 squirting into the air corresponding to an increasing amount of liquids released.

The resin of some squirting burseras consists almost entirely of one compound. Blepharida feeding on squirting plants have responded evolutionarily by cutting the resin canals, which often makes them more susceptible to predation.

It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. They are native often for many species endemic to the Americasfrom the southern United States south through to northern Argentinain tropical and warm temperate forest habitats. The dominance index of its chemical mixture was 0. Alticinae include about 45 species Becerra, ; Furth, ; Evans et al. Squirting species tend to have highly volatile and simple mixtures composed mostly of one or two simple monoterpenes, while non-squirting species have heavier and more complex mixtures.

The monoterpene fraction is small, compared to the squirting species, and the mixture includes more sequiterpenes and diterpenes. A number of species from tropical Asia were once included in this genus, but are now treated in the genus Protium.

Insects cut veins in plants with arborescent resin canals or in plants with laticiferous ducts that do not reticulate. For more details on methodology see Becerra, Extracts were analyzed by gas chromatography. Wikispecies has information related to Bursera.

This evidence suggests that there is a correlation between mechanical and chemical defenses in Bursera.

Individual compounds were identified by matching the obtained spectra with standard mass spectral libraries NBS 7.

In the second category are a series of physical barriers to avoid being eaten.

From Wikipedia, the free encyclopedia. A Simpson dominance index that summarizes the relative abundance of compounds i. United States Department of Agriculture. It seems then, that the antipredator strategy of B. Bursera Bursera simaruba Scientific classification Kingdom: These species may also release an anal secretion or regurgitate when attacked or disturbed by predators Evans et al.

The chemistry of Bursera is dominated by terpenoids, mostly monoterpenes and sesquiterpenes Evans et al.

If the release of a highly pressurized liquid is an effective antiherbivore defense, the chemical nature of the individual components may not be as important as in non-releasing Bursera species.

About one third of the Mexican Bursera species are able to squirt resins when injured, while another third releases little or no fluids. Perhaps the greater chemical complexity of their host makes it more difficult or more energetically expensive to sequester compounds for antipredator defense.

Relative amounts of the main 10 to 15 compounds were used for the Principal Component Analysis. A dendrogram of chemical similarity of Bursera species distinguished four main groups within the genus Fig.

Many lineages in the phylogeny of Bursera contain plants from several of these chemical clusters Becerra, A matrix of Euclidean distances between these species was constructed on the basis of the presence or absence of each compound.
