Composite Shrubs
21 Chapter The sunflower family (Compositae or Asteraceae) is the largest family of flowering plants. Its many species occur around the world as annual and perennial herbs and as shrubs and trees (Chrysothamnus), and matchbrush (Gutierrezia)—make plants of this family among the most common and important plants of the Intermountain area (McArthur and others 1979a; table 1). Shrubs of these gener...
متن کاملFrom observations to experiments in phenology research: investigating climate change impacts on trees and shrubs using dormant twigs.
BACKGROUND AND AIMS Climate change is advancing the leaf-out times of many plant species and mostly extending the growing season in temperate ecosystems. Laboratory experiments using twig cuttings from woody plant species present an affordable, easily replicated approach to investigate the relative importance of factors such as winter chilling, photoperiod, spring warming and frost tolerance on...
متن کاملExpansion of deciduous tall shrubs but not evergreen dwarf shrubs inhibited by reindeer in Scandes mountain range
One of the most palpable effects of warming in Arctic ecosystems is shrub expansion above the tree line. However, previous studies have found that reindeer can influence plant community responses to warming and inhibit shrubification of the tundra.We revisited grazed (ambient) and ungrazed study plots (exclosures), at the southern as well as the northern limits of the Swedish alpine region, to ...
متن کاملSusceptibility of Oregon Forest Trees and Shrubs to Phytophthora ramorum:
Phytophthora ramorum is a recently established invasive pathogen in some mixed-hardwood forests of central coastal California (10,11) and extreme southwestern Oregon (5). It also is known from horticultural nurseries and landscape plantings in Europe (12) and recently was reported from a few nurseries in California and Oregon (6,9). Symptoms are dramatically different on different host species....
متن کاملLegume Shrubs Are More Nitrogen-Homeostatic than Non-legume Shrubs
Legumes are characterized as keeping stable nutrient supply under nutrient-limited conditions. However, few studies examined the legumes' stoichiometric advantages over other plants across various taxa in natural ecosystems. We explored differences in nitrogen (N) and phosphorus (P) stoichiometry of different tissue types (leaf, stem, and root) between N2-fixing legume shrubs and non-N2-fixing ...
