    dataset microenvironment

    No full text
    This dataset provides average values each 30 minute during 12 days for three microenvironmental parameters in the degraded tropical montane forest of Ecuador: VPD (calculated from relative humidity and temperature 15 cm above soil surface), light intensity and soil temperature 5 cm below soil surface

    dataset on the survival and green area of palm seedlings

    No full text
    This excel sheet provides data on the survival and the ratio of green area in leaves of palm seedling during 20 months of experimentation in a tropical montane forest of Ecuador. Treatments in deforested area are: herbivory vs. no herbivory & open area vs. presence of the nurse plant Setaria sphacelata vs. artificial shade. Additionally, a treatment in the adjacent secondary forest has been added. 30 repetitions for each treatment

    Dataset on the portion of palm seedlings grazed

    No full text
    This dataset provides raw data on the portion of palm seedlings grazed in four experimental treatments during a 20 month experiment in the tropical montane forest of Ecuador. 30 repetitions for each treatment. Treatments in open area: control, with the nurse plant Setaria sphacelata, with artificial shade. Additional treatment in the adjacent secondary forest

    Influence of Thermomechanical Processing on Microstructural Evolution in Near-alpha Alloy IMI834

    The effect of processing parameters on the evolution of the microstructural characteristics of IMI834 were examined over the temperature range 950\u20131125 \ub0C at constant strain rates of 0.001\u20131 s 121 and true strains up to 1.2. During isothermal deformation, differences in the flow softening behavior were observed for processing in the single-phase beta region, as compared to the two-phase alpha\u2013beta region, which has been related to differences in the structural changes occurring in IMI834. In particular, deformation processing of the alpha\u2013beta structure was observed to work the lamellar alpha structure of the transformed beta grains without recrystallization of either phase, whilst microstructural development in a predominately beta structure resulted in the formation of dynamically recrystallized grains that were necklaced around the deformed and elongated beta phase. For the later case, the variation in the dynamically recrystallized grain size was determined to follow a Zener\u2013Hollomon relationship between a strain rate range 0.001 and 1 s 121.NRC publication: Ye

    <p>Evidence of resilience to fire in (a) rosettes (red arrows indicate burnt leaf sheaths, yellow arrow points at green shoot), and (b) stemmed individuals (yellow arrow indicates transition to burnt area of stem); the individual was alive with a full crown. Stem diameter and internode compression in response to fire or mechanical damage in (c) a living J3, and (d) a reproducing adult (arrows point at compressed area). Activities carried out in Ocol that involve the felling of preferably old individuals. (e) Wax extraction for candle production; home construction, including (f) roofs, (h, j) walls, (i) floors, and (g) fences. Sequence of resilient J2 (large rosettes) to J3 growing at a lot of 5 hectares that had been deforested 7.5 years ago and then burnt, as informed by the landowner; (k) vigorous J2 with no stem, (l—n) J3 of different heights (and ages); (k—m) arrows point at pieces of logged palm stems still present at the lot, indicating recent time since deforestation.</p

    Satellite images and general sceneries revealing patterns of deforestation at each studied site.

    <p>Left, images of the Instituto Agustín Codazzi Geoportal, scale bars = 4.67 km (a-c), and institutional aerial photograph without scale of the Instituto de Investigación de la Amazonía Peruana, standing in representation of general landscape composition since satellite images of this site were not available for publication (d). Right, general sceneries of the four studied sites (including palms). In Roncesvalles, a general matrix of pastures surrounds several fragments of forest; at Ocol, a general fragment of forest surrounds several fragments of pastures; at Salento and La Línea, deforestation extent resembles that of Roncesvalles, but there are more fragments of forest, and these are more connected; percent of forest cover at each site is indicated in parenthesis: Roncesvalles (11%), Ocol (84%), Salento (46%) La Línea (42%). </p
