Bursera schlechtendalii and Bursera biflora are representative of the squirting and non-squirting syndromes respectively. The dogbane beetle Chrysochus auratus that feeds on Apocynum cannabinum Apocinaceae chews a channel that transects major veins adjacent to the leaf margin. Bursera glabrifolia Kunth Engl. This slows their growth, delays pupation, and increases their risk of predation Becerra, a. Views Read Edit View history. The dendrogram of chemical similarity of Bursera species showed a remarkable correspondence to groupings of species based on their squirt response.
Bursera medranoana Schlrchtendalii microphylla A. Low scores on the first principal component signify a lack of compounds of low retention time. The rupture of the laticifers stops the flow of latex to the margin of the leaf that is subsequently consumed by these beetles Williams, United States Department of Agriculture. A Simpson dominance index that summarizes the relative abundance of compounds i.
In other plant-herbivore systems, the bursega properties of the resins are determined by their terpenoid composition. Bursera Bursera simaruba Scientific classification Kingdom: Furthermore, larvae whose natural shields were removed and then reared on a diet of lettuce were defenseless.
In the second category are a series of physical barriers to sdhlechtendalii being eaten. This article was originally published in. Thus, this beetle species does not sequester the chemical compounds of its host in its body or feces. Early-instar larvae are apparently unable to sever the leaf veins. Leaves of 38 species were collected in the field and their chemical constituents extracted in ethyl acetate.
Citing articles via Google Scholar. As with other canal-bearing plant species, damage causes an immediate release of fluids from the site of injury.
Neotropical Plant Portal – Bursera schlechtendalii
The squirt defense has detrimental effects even on these specialized vein-cutting herbivores. Squirting burseras tend to have more schlechtendaalii chemical mixtures dominated by one or two monoterpenes while non-squirting burseras have mixtures involving sesquiterpenes schllechtendalii diterpenes. Perhaps the link to terpene squirting provides a clue. Blepharida species that feed on non-squirting, chemically more complex plants do not obtain bugsera indirect benefit of protection from their hosts and have developed schlechtenvalii alternative behavioral defense.
They are strong barriers against insects that are unable to deal with large quantities of latex, resin or other fluids Farrell et al. They feed by mining the leaves, but they sometimes rupture the canals and die because they become covered by resins. 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. In other projects Wikimedia Commons Wikispecies.
Their high cost is due to extensive chemical reduction mediated by ATP and NADPH and the expense of producing specific enzymes that catalyze the reactions along the biosynthetic pathway. Comparative biology of defense and antipredator defense in schllechtendalii genus Blepharida and its hosts. A matrix of Euclidean distances between these species was constructed on the basis of the presence or absence of each compound.
The chemical analyses of the body and frass of Blepharida flavocostata revealed almost no match to the constituents found in B.
Biodiversity of Costa Rica
The significant positive correlation between the strength of squirt response and the first principal component of chemical composition provides some insight into the nature of the relationship between the two defenses Fig. Germplasm Resources Information Network. In many species, canals transport antiherbivore repellents and toxins. Yet, this does not explain why only one or two monoterpenes dominate the mixture. Squirt strength was documented by cutting 5 to 20 leaves on multiple individuals per species with nail clippers.
Chemical analysis of the extracts of Blepharida Schiechtendalii and Bursera schlechtendalii. Bursera linanoe La Llave Rzed. Bars indicate the relative amounts of the different compounds found, according to their retention times in the gas-chromatograph. This page was last edited on 10 Octoberat When such plants are damaged, there is an immediate release of fluids from injured tissues, often in copious quantities. Cluster 1 consists mostly of species that release abundant resins when injured, often in the form of a squirt.
SERNEC – Bursera schlechtendalii
These include structures such as spines, trichomes, and hard, very schlechtendali, or smooth surfaces. Bursera Burseraceae genera Sapindales stubs. Relative amounts of the main 10 to 15 compounds were used for the Principal Component Analysis.
