Premise Epiphytes have commensal relationships with their host trees. Besides the influence of tree traits, little has been discussed concerning ecology epiphytes in disturbed habitats (e.g., pasture). We herein tested whether occurrences pasture and forest specialist pastures are affected differently by traits. hypothesized that (H1) richness abundance generalist would be positively associated...
Much of the protected habitat available to the threatened Marbled Murrelet Brachyramphus marmoratus and other old-growth associated species in the Pacific Northwest is in narrow strips along the coast (e.g., parks and scenic fringes). Using data over two years from three watersheds on southwest Vancouver Island, we show that such shoreline strip forests represent suboptimal habitat for murrelet...
We report on nests of radio-marked marbled murrelets (Brachyramphus marmoratus) nesting in unusual habitats in southwestern British Columbia. We found 1 confirmed and 2 probable marbled murrelet nest sites on cliffs. These represent the 1st substantiated accounts of ground nesting in this species south of Alaska. In addition, we found a marbled murrelet nesting in a 130 (?5)-yr-old red alder (A...
Polypodium appalachianum: An Unusual Tree Canopy Epiphyte in the Great Smoky Mountains National Park
Changes in stem diameter of orchid plants were investigated in a control growing climate. Previous studies have focused on stem diameter in relation to plant water on terrestrial plants in order to schedule the irrigation. The objective of this work was to evaluate the ability of the strain gauges to capture changes in the epiphytes plant stem. Experiments were carried out by using the sympodia...
A unique chlorinated macrocyclic lactone, termed oocydin A, was isolated from a strain of Serratia marcescens growing as an epiphyte on Rhyncholacis pedicillata, an aquatic plant native to the Carrao river of the Venezuelan-Guyanan region of South America. The lactone has a molecular mass of 470 Da, and contains one atom of chlorine, a carboxyl group and a tetrahydrofuran ring internal to a lar...
We report the complete mitochondrial genome sequence of the flowering plant Amborella trichopoda. This enormous, 3.9-megabase genome contains six genome equivalents of foreign mitochondrial DNA, acquired from green algae, mosses, and other angiosperms. Many of these horizontal transfers were large, including acquisition of entire mitochondrial genomes from three green algae and one moss. We pro...
