The species of the genus Deyeuxia (Poaceae, Pooideae) from Argentina and nomenclatural notes. Darwiniana 44(1): 131-293. This first revision of the genus Deyeuxia in Argentina revealed 58 native taxa from America, three of them endemic to Argentina, and the remaining ones also growing in Bolivia, Brasil and Chile. Three new taxa are described for science: Deyeuxia alba subsp. breviaristata (Argentina, Brasil and Uruguay); Deyeuxia heterophylla var. puberilemma (Perú); Deyeuxia trichodonta var. hirsuta from (Argentina: Salta). The following taxa are new records for Argentina, Bolivia, Chile and Ecuador: Deyeuxia brevifolia var. brevifolia and Deyeuxia brevifolia var. expansa (Chile); Deyeuxia cabrerae var. cabrerae, D. cabrerae var. aristulata (Chile); D. cabrerae var. trichopoda (Chile); Deyeuxia curta (Ecuador); D. diemii (Chile); Deyeuxia filifolia (Chile); Deyeuxia hackelii (Chile); Deyeuxia minima (Argentina and Ecuador); Deyeuxia sclerantha (Ecuador); Deyeuxia spicigera var. spicigera Chile); Deyeuxia spicigera var. cephalotes (Argentina) and Deyeuxia trichodonta var. trichodonta (Bolivia). The new name Deyeuxia nana, for Agrostis caespitosa, and the following new combinations are estab- lished: Deyeuxia reitzii, Deyeuxia rupestris f. pilosa, Deyeuxia rupestris var. minor, D. tarmensis var. macrochaeta, and Deyeuxia velutina var. nardifolia. New synonyms are established for Deyeuxia hete- rophylla (Calamagrostis mulleri, Calamagrostis macbridei); Deyeuxia rupestris f. pilosa (Calama- grostis leonardii, Calamagrostis longearistata f. pilosa) and Calamagrostis epigeios (Calamagrostis chilensis). This revision includes a critical evaluation of morphological characters (some of them stud- ied by SEM) with taxonomic value at the generic and species level, and relationships among Deyeux- ia and its closest genera are discussed. Nomenclatural considerations about problematic taxa, keys to Deyeuxia and related genera, and also to the species and subspecific taxa, descriptions, synonyms, illustrations, geographical distribution, ecological observations and vernacular names for every species are presented in detail.

    CONDUIT AND ERUPTION DYNAMICS OF THE 1912 VULCANIAN EXPLOSIONS AT NOVARUPTA, ALASKA A DISSERTATION SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI‘I AT MĀNOA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN GEOLOGY AND GEOPHYSICS December 2017 By Samantha Jo Isgett Dissertation Committee: Bruce F. Houghton, Chairperson Helge M. Gonnermann Christina Neal Thomas Shea John Allen © 2017, Samantha Jo Isgett ii Acknowledgements I probably would not be “standing here today” if my advisor Bruce Houghton had not introduced me to the wonderful world of volcanology. I entered his 300 level volcanology class as a naïve sophomore who had no ambitions of going to graduate school and left knowing that I wanted to be volcanologist and the steps that I needed to take to get there. Bruce has a passion not only for solving the big science question, but also in passing on his knowledge and skill-sets to his students. I cannot thank Bruce enough for seeing in me the potential makings of a scientist and guiding me there. It was, and always will be, a privilege to work with you. I would like to thank my committee — Helge Gonnermann, Thomas Shea, Christina Neal, and John Allen — for pushing me to take every problem and interpretation just a little (or a lot) further. I am especially grateful to Tom and John for stepping in at the last hour. Thank you all for your time and patience. Alain Burgisser, Laurent Arbaret, and Sarah Fagents also brought outside perspectives and skill-sets that were crucial for this project.

  • Diversidad De Plantas Y Vegetación Del Páramo Andino
    Plant diversity and vegetation of the Andean Páramo Diversidad de plantas y vegetación del Páramo Andino By Gwendolyn Peyre A thesis submitted for the degree of Doctor from the University of Barcelona and Aarhus University University of Barcelona, Faculty of Biology, PhD Program Biodiversity Aarhus University, Institute of Bioscience, PhD Program Bioscience Supervisors: Dr. Xavier Font, Dr. Henrik Balslev Tutor: Dr. Xavier Font March, 2015 Aux peuples andins Summary The páramo is a high mountain ecosystem that includes all natural habitats located between the montane treeline and the permanent snowline in the humid northern Andes. Given its recent origin and continental insularity among tropical lowlands, the páramo evolved as a biodiversity hotspot, with a vascular flora of more than 3400 species and high endemism. Moreover, the páramo provides many ecosystem services for human populations, essentially water supply and carbon storage. Anthropogenic activities, mostly agriculture and burning- grazing practices, as well as climate change are major threats for the páramo’s integrity. Consequently, further scientific research and conservation strategies must be oriented towards this unique region. Botanical and ecological knowledge on the páramo is extensive but geographically heterogeneous. Moreover, most research studies and management strategies are carried out at local to national scale and given the vast extension of the páramo, regional studies are also needed. The principal limitation for regional páramo studies is the lack of a substantial source of good quality botanical data covering the entire region and freely accessible. To meet the needs for a regional data source, we created VegPáramo, a floristic and vegetation database containing 3000 vegetation plots sampled with the phytosociological method throughout the páramo region and proceeding from the existing literature and our fieldwork (Chapter 1).

  • THE ANDEAN NORTHWEST T E N a L 243 P Y L E N O L
    © Lonely Planet 243 The Andean Northwest In stark contrast with the low, flat, humid northeast, Argentina’s northwest sits lofty, dry and tough beneath the mighty Andes. Nature works its magic here with stone: weird, wonderful and tortured rockscapes are visible throughout, from the imposing formations of the Parque Nacional Talampaya in the far south to the twisted strata of the Quebrada de Cafayate; from the jagged ruggedness of the Valles Calchaquíes to the palette of colors of the Quebrada de Humahuaca. And always to the west is the brooding presence of magnificent peaks. The area has an Andean feel with its traditional handicrafts, Quechua-speaking pockets, coca leaves, llamas, the indigenous heritage of the inhabitants, Inca ruins, and the high, arid puna (Andean highlands) stretching west to Chile and north to Bolivia. The region’s cities were Argentina’s first colonial settlements and have a special appeal. The quiet gentility of Santiago del Estero recalls bygone centuries, Salta’s beauty makes it a favorite stop for travelers, while resolutely urban Tucumán, a sugarcane capital, seems to look firmly to the future. Several popular routes await. From Salta you can take in the cactus sentinels of Parque Nacional Los Cardones on your way to gorgeous Cachi, and then head down through the tradi- tional weaving communities of the Valles Calchaquíes to Cafayate, home of some of Argentina’s best wines. Another route from Salta soars into the mountains to the puna mining settlement of San Antonio de los Cobres, heads north to the spectacular salt plains of the Salinas Grandes, and then down to the visually wondrous and history-filled Quebrada de Humahuaca.

ASSEMBLAGES OF BIRD AND MAMMAL COMMUNITIES IN TWO MAJOR ECOLOGICAL UNITS OF THE ANDEAN HIGHLAND PLATEAU OF SOUTHERN PERU ESTRUCTURA DE LAS COMUNIDADES DE AVES Y MAMÍFEROS EN DOS UNIDADES ECOLÓGICAS DE LOS ANDES DEL SUR DEL PERÚ Oswaldo Ramirez1, Margarita Arana1, Enrique Bazán1, Angel Ramirez2 y Asunción Cano2 Abstract Grasslands in the Andean highlands plateau of southern Peru have been considered as a single and homogeneous dry habitat also known as Puna. However, in some regions, a highest rainfall regimen is found, and the name of wet puna has begun to be used by some authors. Since no studies have been carrying out specifically to test if dry and wet puna are different ecological units, we chose two representative localities of each one of these habitat to evaluate assemblages of bird and mammal communities and their continuity or independence between these apparently similar habitats. Our results suggest that wet puna has different mammal diversity than dry puna, and a heterogeneous bird community with species that have been previously reported exclusively in paramo or exclusively in puna. In spite of the apparent uniform flora in the Andean highlands of South Peru, data suggest that rainfall regimens produce a mosaic of habitats that will be determining ecological barriers for terrestrial mammals, in particular for small mammals. Key words: Andean grasslands, Andean plateau, Cuzco, Oriental Cordillera, paramo, puna, Puno. Resumen Los Pajonales de los Andes del sur del Perú, también conocidos como Puna, son considerados como hábitats homogéneos y secos.
