An Environmental History of the Middle Rio Grande Basin
United States Department of From the Rio to the Sierra: Agriculture Forest Service An Environmental History of Rocky Mountain Research Station the Middle Rio Grande Basin Fort Collins, Colorado 80526 General Technical Report RMRS-GTR-5 Dan Scurlock i Scurlock, Dan. 1998. From the rio to the sierra: An environmental history of the Middle Rio Grande Basin. General Technical Report RMRS-GTR-5. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 440 p. Abstract Various human groups have greatly affected the processes and evolution of Middle Rio Grande Basin ecosystems, especially riparian zones, from A.D. 1540 to the present. Overgrazing, clear-cutting, irrigation farming, fire suppression, intensive hunting, and introduction of exotic plants have combined with droughts and floods to bring about environmental and associated cultural changes in the Basin. As a result of these changes, public laws were passed and agencies created to rectify or mitigate various environmental problems in the region. Although restoration and remedial programs have improved the overall “health” of Basin ecosystems, most old and new environmental problems persist.

The Phenology of Plants in the Humid Tropics
The Phenology of Plants in the Humid Tropics P. R. WYCHERLEY1 Abstract Meteorological phenomena (as indicated by cloudiness and hours of bright sunshine) reinforce or modify the relatively small differences in daylength which result from astronomical conditions. Examples of photoperiodism are discussed in relation to this. The 'storm' stimulus (fast-falling temperature and/or breaking of water stress) stimulates anthesis in representatives of several families of flowering plants. The flowering of evergreen forest trees (e.g. Dipterocarpaceae) at irregular intervals is attributed to preceding periods with large diurnal temperature ranges and high maximum temperatures in dicating high insolation (which is probably the main inductive factor, because of consequent bio chemical conditions associated with accumulation of assimilates and high carbohydrate status). Such flowering is thus not attributed to drought. Flowering in many deciduous trees follows leaf-fall and/or new leaf appearance. Floral initiation may occur during a period when the tree bears only senescent leaves. Leaf abscission, and thus subsequent emergence of new leaves and flowers, appears to be a response to drought. Susceptibility to dry periods in particular seasons, more than in others, may be due to lack of response by new leaves not yet 'hardened' which results in an insensitive period, followed by a phase in which senescence is accelerated by photoperiodic conditions. In this last phase the foliage is sensitized. Following the discovery of vernalization by the chilling of germinating seed (Gassner, 1918) and of photoperiodism or the effect of daylength (Garner and Allard, 1920), the environmental stimuli operative in many flowering plants of the temperate regions have become evident. -

J. Orchid Soc. India, 30: 1-10, 2016 ISSN 0971-5371 DEVELOPMENT OF MALLLEEE AND FEMALLLE GAMETOPHYTES IN HABENARIA OVVVALIFOLIA WIGHT (ORCHIDAAACCCEEEAAAE) M R GURUDEVAAA Department of Botany, Visveswarapura College of Science, K.R. Road, Bengaluru - 560 004, Karnataka, India Abstract The anther in Habenaria ovalifolia Wight was dithecous and tetrasporangiate. Its wall development confirmed to the monocotyledonous type. Each archesporial cell developed into a block of sporogenous cells and finally organized into pollen massulae. The anther wall was 4-5 layered. The endothecial cells developed ring-like tangential thickening on their inner walls. Tapetal cells were uninucleate and showed dual origin. The microspore tetrads were linear, tetrahedral, decussate and isobilateral. The pollens were shed at 2-celled stage. The ovules were anatropous, bitegmic and tenuinucellate. The inner integument alone formed the micropyle. The development of embryo sac was monosporic and G-1a type. The mature embryo sac contained an egg apparatus, secondary nucleus and three antipodal cells. Double fertilization occurred normally. Introduction species. THE ORCHIDACEAE, one of the largest families of Materials and Methods angiosperms is the most evolved amongst the Habenaria ovalifolia Wight is a terrestrial herb with monocotyledons.

Reconstructing the Basal Angiosperm Phylogeny: Evaluating Information Content of Mitochondrial Genes
55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships. -

E-mail: [email protected] The main phytogeographic regions within the eastern part of the Indochinese Peninsula are delimited on the basis of analysis of recent literature on geology, geomorphology and climatology of the region, as well as numerous recent literature information on phytogeography, flora and vegetation. The following six phytogeographic regions (at the rank of floristic province) are distinguished and outlined within eastern Indochina: Sikang-Yunnan Province, South Chinese Province, North Indochinese Province, Central Annamese Province, South Annamese Province and South Indochinese Province. Short descriptions of these floristic units are given along with analysis of their floristic relationships. Special floristic analysis and consideration are given to the Orchidaceae as the largest well-studied representative of the Indochinese flora. 1.
