Global change is impacting forests worldwide, leading to shifts in forest dynamics and functional composition. We evaluated the changes in the liana community and trait composition over a five‐year period (2014–2019) in a Chinese tropical rainforest and assessed the underlying putative mechanisms. We monitored >20,000 lianas in a 20‐ha plot, and analyzed community changes for each of the 20 1‐ha plots. To identify the putative drivers underlying community change, we used community‐weighted mean (CWM) trait values of 18 functional traits that are important for liana performance. During the 5‐year period, liana density decreased by 12.6% because of the high mortality of small lianas, whereas liana basal area increased by 5.8% because of the high growth of large lianas. After 5 years, liana communities showed a shift in trait values indicating that they changed towards more large, acquisitive lianas with rapid water use. The temporal shift from slow to fast community trait spectra in carbon, nutrient, and water use was also supported by shifts in the individual CWM traits, from conservative tough leaves towards more acquisitive and water‐spending leaves with higher K concentration, leaf thickness, and vessel diameter. Overall, we found no support for a role of disturbances or drought as drivers of the observed changes in the studied liana community. Instead, our study implies that CO2 fertilization should be considered to better understand dynamics in liana communities in tropical forests.Abstract in Chinese is available with online material.

“…In the process of planting and harvesting, the transportation of agricultural materials and fruits mainly depends on manpower, which results in low productivity and high labor intensity. With the increasing scarcity of labor force, the role of mechanized transportation in the citrus production process is becoming more and more obvious [3][4][5].…”

In order to reduce operation risk and working intensity in mountainous orchard transportation and to realize optimized control for the mountainous orchard electric-drive monorail transportation system, a mountainous orchard electric-drive monorail transporter control system was designed and developed in this study. The system mainly consists of modules as: manual and remote control, positioning, obstacle avoidance, speed measurement, motor control, electric-magnetic break, and the position limit. The driving speed, current consumption, break control, and battery pack running ability experiments were conducted to test the control system. Results indicated that, the transporter’s driving speed is 0.60~0.58 m/s when it is running on the ground with the load weight from 0 to 100kg. This speed is little affected by the load weight. The transporter’s driving speed is 0.45~0.28 m/s when it is climbing a steep hill with an angle of 39°. That speed is critically affected by the load weight. In further improvements, a shift mechanism will be introduced so that adjustable gear ratio could be achieved thus solve the current overload problem in a full load situation.

To analyze the structure and performance of Outlast acrylic fiber, the fiber structure was observed respectively by FTIR spectra, X-ray diffraction and scanning electron microscope, the normal physical and mechanical properties were measured, and the thermo-regulated performance was investigated by differential scanning calorimeter, thermal gravimeter analysis and step cooling test. The results indicate that the structure and normal physical and mechanical properties of Outlast acrylic fiber are slightly different from that of normal acrylic fiber. Both the melting peak and crystallization peak of Outlast acrylic fiber are single peaks, and the phase change temperature range is applicable and the phase change enthalpy is high. The decomposition temperature of Outlast acrylic fiber is around 311.85°C. The cooling velocity of Outlast acrylic fiber decreases exponentially with the increase in time, and the thermo-regulated ability of Outlast acrylic fiber is better than that of normal acrylic fiber.
