The in vitro anti-Babesia canis activities of nine essential oils were investigated. Among the tested Achillea millefolium, Eugenia caryophyllus and Citrus grandis most active (IC50 values 51.0, 60.3 61.3 μg/mL, respectively). from Abies sibirica, Rosmarinus officinalis, Eucalyptus globulus, Cinnamonum zeylanicum, Mentha piperita Pinus sylvestris less 134.3, 237.3, 239.3, 367.9, 837.5 907.3 res...

Forest pathogens and insects can accelerate tree mortality, increase stand structural heterogeneity, and alter tree community composition. In northern California, the canopy trees Abies concolor var. lowiana (Gord. & Glend.) Lemmon (white fir) and Pseudotsuga menziesii var. menziesii (Mirbel) Franco (Douglas-fir) co-occur but vary in shade tolerance and regenerative abilities following disturba...

The self-rejection system of Dipterocarpus tempehes (Dipterocarpaceae), an emergent tree of the lowland tropical forests of Borneo, were studied by means of pollination experiments, fluorescence microscopy of pollen tubes, and monitoring of ovary maturation patterns. Fruit set was higher in cross-pollinated flowers than in control and self-pollinated flowers, indicating the existence of pollen ...

Reiteration is an important process in the maintenance of tree crowns and in plant longevity. We use a geometric simulation model of branch growth to explore differences in longevity between old-growth Pseudotsuga menziesii (Mirb.) Franco and Abies grandis (D. Don ex Lamb.) Lindl. branches. Reiteration is defined through rules that reflect apical dominance relationships, and these rules are use...

MCCUNE, B., and T. F. H. ALLEN. 1985. Will similar forests develop on similar sites? Can. J. Bot. 63: 367-376. Abies grandis, Taxus brevifolia, Thuja plicata, or any combination of these may dominate old-growth mesic forests of the Bitterroot Canyons, western Montana. Similar sites need not develop similar, relatively stable forests. This is shown by (i) anomalous distributional patterns of tre...
