Ecology Letters (2012) 15 : 666–672 Abstract Grasses such as bamboos can produce upright stems more than 30 m tall, yet the processes that constrain plant height in this important group have never been investigated. Air embolisms form commonly water transport system of grasses and we hypothesised root pressure‐dependent refilling these should limit maximum grass species to magnitude their pressure. Confirming hypothesis, show 59 bamboo grown two common gardens, heights culms 67 clones are...
Despite considerable investigations of diurnal water use characteristics in different plant functional groups, the research on daily strategies woody bamboo grasses remains lacking. We studied and gas exchange Sinarundinaria nitida (Mitford) Nakai, an abundant subtropical species Southwest China. found that stem relative content (RWC) hydraulic conductivity (Ks) this did not decrease significantly during day, whereas leaf RWC conductance (Kleaf) showed a distinct at midday, compared with...
Polyploidization is hypothesized to improve the freezing resistance of plants in cold regions. However, adaptive strategies and key physiological mechanisms involved resistant ability polyploids remain unclear. In Actinidia chinensis (kiwifruits), tetraploids hexaploids occupy higher altitude habitats with colder climates than diploids, providing a study system investigate responsible for differentiation between cytotypes. We characterized environmental conditions their natural distribution...
Summary Wood decomposition is a key process in the terrestrial carbon cycle, controlling storage with feedback to climate. In (sub) tropical forest, termites are major players wood decomposition, but their role relative that of microbial decomposers and traits different tree species poorly understood. The current literature also has strong bias towards dicot while abundant woody monocots, particularly bamboos, contribute greatly cycling. Here, we present first experiment disentangle effects...
Epiphytes are an important component of tropical and subtropical flora, serve vital ecological functions in forest hydrology nutrient fluxes. However, they often encounter water deficits because there is no direct contact between their roots the soil. The strategies employed by epiphytes for maintaining balance relatively water-limited habitats not completely understood. In present study, we investigated anatomical traits, loss rates, physiology leaves pseudobulbs four Dendrobium species...
To understand water-use strategies of woody bamboo species, sap flux density (Fd) in the culms a (Bambusa vulgaris Schrader ex Wendland) was monitored using thermal dissipation method. The daytime and night-time Fd were analyzed dry rainy seasons. Additionally, diurnal changes root pressure, culm circumference, stomatal conductance (gs) investigated to characterize mechanisms used maintain water balance bamboos. Both seasons, responded vapor pressure deficit (VPD) an exponential fashion,...
Abstract Competitive interactions drive critical ecological processes in plant communities. Yet, how competitive are influenced by polyploidy that has a widespread incidence plants remains largely unknown. To evaluate the hypothesis of asymmetry between polyploids and diploids, we competed tetraploid diploid perennial herbaceous Chrysanthemum indicum L. (Asteraceae) at different relative frequencies under contrasting soil water contents. We quantified interaction intensity competing same...

Longma, Southwest China" Xue‐You Li, Shi‐Jian Yang and Yang, published online on September 17, 2010, in Wiley Online Library (http://onlinelibrary.wiley.com), has been retracted agreement between the authors, journal's Executive Editor, Jason V. Watters, publisher, Periodicals, Inc. retraction agreed due to overlap this American Journal Primatology: "Diet feeding behavior...
Abstract Desiccation-tolerant (DT) plants can withstand dehydration to less than 0.1 g H2O g−1 dry weight. The mechanism for whole-plant recovery from severe is still not clear, especially woody DT plants. In the present study, we evaluated desiccation tolerance and of a potentially new resurrection plant Paraboea rufescens (Gesneriaceae). We monitored leaf water status, gas exchange, chlorophyll fluorescence root pressure potted P. during rehydration, investigated content leaves in field...
Abstract This study combines laboratory experiments and discrete element simulation methods to analyze the mechanism deterioration patterns of sandstone surrounding rock voiding bottom a heavy-haul railway tunnel. It is based on previously acquired measurement data from optical fiber grating sensors installed in Taihangshan Mountain Tunnel Wari Railway. By incorporating particle wastage rate results, method for calculating peak strength elastic modulus attenuation proposed. Research...
<title>Abstract</title> Using the Chongqing University City double-track tunnel project as a case study, this study comprehensively applied field measurements and numerical simulation methods to analyze impact of over-undercuts during construction on stability using finite element simulation. Intelligent scanning equipment for excavation contours, over-undercut conditions surrounding rock after blasting were measured in detail. The software ANSYS was employed establish stratum structure...
A plant species can have diverse hydraulic strategies to adapt different environments. However, the water transport divergence of co-occurring in contrasting habitats remains poorly studied but is important for understanding their ecophysiology adaptation Here, we investigated whole-branch, stem and leaf associated morphology traits 11 Yuanjiang valley-type savanna (YJ) with dry–hot Xishuangbanna tropical seasonal rainforest (XSBN) wet–hot habits tested hypothesis that plants YJ a lower...
On the ground of preliminary study Taihangshan Mountain Tunnel, it was observed that under water-rich conditions, long rolling heavy-haul trains will deteriorate surrounding rock, thereby causing damage to bottom structure. Combined with data from long-term field monitoring and discrete element analysis, after clarifying law bedrock deterioration, fuyingzi tunnel Zhangtang railway in China is taken as research object fatigue damage. Ansys Workbench simulation software used further compare...
SUMMARY The control effect of Cucurbita ficifolia (pumpkin) leaf acetone extract on caterpillars the small cabbage butterfly Pieris rapae Linnaeus (Lepidoptera: Pieridae) was observed in laboratory and field experiments from 1 March 2006 to 30 May 2007. mechanism action by which pumpkin (PLE) controls examined for feeding restraint, values 0·50 restraint concentration (FC 50 ) 0·95 95 after 12 24 h were estimated. results showed that absolute anti-feeding activity fourth instar 0·65 0·56,...
As the typical local rose species in Xinjiang, R. beggeriana and laxa are highly similar morphology except that sepals deciduous while they persistent after hips ripening. Both had been applied to interspecific hybridization with modern cultivars for introgressions of stress-resistances. In this study, from three populations four varied different altitudes selected ploidy karyotype analysis. The results showed diploid tetraploid respectively. karyotypes seven two all identified as small...
Niche shift between polyploid and diploid plants is an important requirement for the success of polyploid. Diploid, tetraploid, hexaploid kiwifruit distribute in different areas. Whether there obvious niche differentiation major environmental factors which could influence ecological ploidy kiwifruits are still unknown. Based on natural distribution information collected from literature by field works, maximum entropy model (MaxEnt) was used to predict potentially suitable ranges climatic...
