Carbon stock and diversity of species together address the two most pressing concerns for successful ecosystem functioning management, namely climate change biodiversity loss. Understory vegetation is a significant indicator plant biodiversity, contributing to forest carbon storage, sustaining species, providing many ecological services. However, little research has been done about contribution understory in forests, likely because these components only make up small portion total ecosystem....
This paper investigates the performance of AlGaN/gallium nitride (GaN) MIS high electron mobility transistors (MIS-HEMTs). The gate dielectric layer and surface passivation are formed by low-pressure chemical vapor deposition (LPCVD) Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> N xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> .

Abstract We used a continuous 9 year (2003–2011) eddy flux time series with 30 min resolution to examine water use efficiency in tropical rainforest and determine its environmental controls. The multiyear mean ( W ue ) of this was 3.16 ± 0.33 gC per kg H 2 O, which is close that boreal forests, but higher than subtropical lower temperate forests. vapor deficit V PD had strong impact on instantaneous , the manner predicted by stomatal optimization theory. At seasonal scale, temperature...
In this letter, we report an in-situ predeposition plasma nitridation process, which is adopted to remove the GaN surface oxygen-related bonds and reduce dangling by forming Ga-N prior low-pressure chemical vapor deposition (LPCVD)Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> N xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> deposition. It demonstrates that Vth hysteresis current collapse of device were dramatically improved due...
Abstract Background Dai, Hani, and Yao people, in the trans-boundary region between China, Laos, Vietnam, have gathered plentiful traditional knowledge about wild edible plants during their long history of understanding using natural resources. The ecologically rich environment multi-ethnic integration provide a valuable foundation driving force for high biodiversity cultural diversity this region. However, little study has uncovered unique attractive culture to world. Methods We conducted...
This letter presents a fabrication technology of enhancement-mode (E-mode) AlGaN/GaN metal-insulator- semiconductor high-electron mobility transistors (MIS-HEMTs) using 10 keV fluorine ion implantation. An 8 nm low-pressure chemical vapor deposition silicon nitride layer was deposited on the AlGaN as gate dielectric and energy-absorbing that slows down high energy (10 keV) ions to reduce implantation damage. The E-mode MIS-HEMTs exhibit threshold voltage +3.3 V with maximum drain current...
Abstract Epiphytic communities offer an original framework to disentangle the contributions of environmental filters, biotic interactions and dispersal limitations community structure at fine spatial scales. We determine here whether variations in light, microclimatic conditions host tree size affect variation species composition phylogenetic epiphytic bryophyte communities, hence, assess contribution filtering, constraints competition assembly. A canopy crane giving access 1.1 ha tropical...
Global biodiversity loss and mass extinction of species have raised serious global concerns, especially in fragile ecosystems. Karst forest, a well-known ecosystem, is served as natural laboratory for biogeographical, ecological, evolutionary, taxonomic research. However, richness distribution patterns karst forests largely remain unclear. Orchidaceae has been regarded the "flagship" group plant diversity. In this study, we use Wanfengshan Nature Reserve southeast Yunnan, China, model to...
Abstract The patterns, components, and controls of soil respiration in an old‐growth subtropical forest were investigated using automatic chamber system. We measured three treatments (control, trenching, litter removal) over 15 months. annual total (1248 gC m –2 yr –1 ) showed considerable spatial variation (coefficient = 27.8%) within the forest. Thirty samples required to obtain results 10% mean value at a 95% confidential level. A distinctive cosine‐like diel pattern was observed; time...
Abstract Question We investigated the bryophyte communities on tree boles along three altitudinal gradients located within different types of forested area to answer following questions: (1) how many bole epiphytic species are there; (2) what dominant species; (3) richness patterns gradients; and (4) major drivers conservation implications these patterns? Location Three protected areas in sub‐montane (Mengla transect: 800–1400 m), montane (Zhenyuan 2000–2600 m) sub‐alpine (Lijiang 3200–3800...
Abstract Without any root contact with the soil, epiphytic bryophytes must experience and explore poor, patchy, heterogeneous habitats; while, nitrogen (N) uptake use strategies of these organisms remain uncharacterized, which obscures their roles in N cycle. To investigate sources, preferences, responses to enhanced deposition bryophytes, we carried out an situ manipulation experiment via 15 labelling technique Asian cloud forest. Epiphytic obtained more from air than bark, but contribution...
As heterotrophic respiration (R(H)) has great potential to increase atmospheric CO2 concentrations, it is important understand warming effects on R(H) for a better prediction of carbon-climate feedbacks. However, remains unclear how responds in subtropical forests. Here, we carried out trenching alone and with treatments test the climate effect forest southwestern China. During measurement period, increased annual soil temperature by 2.1 °C, mean 22.9%. Warming (WE(T)) showed very similar...
Summary Few studies have explored how – within the same system clonality and positive plant–plant interactions might interact to regulate plant community composition. Canopy‐dwelling epiphytes in species‐rich forests provide an ideal for studying this because many epiphytic vascular plants undertake clonal growth colonize canopy habitats after formation of nonvascular epiphyte (i.e. bryophyte lichen) mats. We investigated integration seven dominant influenced inter‐specific between a...
Fog may be an important source of water for forest vascular epiphytes on trees, because they lack direct access to sources soil water, but little is known about the use proportions from various and potential uptake pathways in epiphytes. Here, we analyzed leaf carbon isotope ratios as a measure efficiency (WUE), fog, rain, use, foliar (FWU) species epiphyte their host trees tropical karst dwarf China during dry season. We found that WUE, represented by δ13C, was generally enriched compared...
