| patterns of growth, reproduction, defense, and herbivory in the dioecious shrub baccharis halimifolia (compositae). | patterns of growth, reproduction, defense (leaf resin) and herbivory were compared between the sexes of the dioecious shrub baccharis halimifolia (compositae). male plants possessed longer shoots and more tender leaves, grew faster, and flowered and senesced earlier than female plants. levels of leaf nitrogen, water content, and acetone-soluble resin (shown to deter feeding by polyphagous insect herbivores) did not differ between male and female plants. when offered a choice between leaves from ... | 1990 | 22160109 |
| feeding responses of adapted and non-adapted insects to the defensive properties of baccharis halimifolia l. (compositae). | trirhabda bacharidis (weber) (chrysomelidae), a univoltine, monophagous beetle is the dominant herbivore on baccharis halimifolia (compositae), a woody, perennial shrub that leafs out in early spring and retains its leaves into november. available plant biomass increases during the season but t. bacharidis feeds only during spring and early summer. during the remainder of the growing season, there are no major herbivores feeding on b. halimifolia. b. halimifolia leaves increase in toughness and ... | 1982 | 28310500 |
