“…The plant hydraulic system is tightly linked to its water and carbon metabolism (Christoffersen et al, ; Eller et al, ) and therefore it is likely that plants require adjustments in their hydraulic system to maintain a positive carbon balance in the face of climate change. Several studies have shown plastic responses (variations in phenotype expression in response to environmental change) of leaf physiology and plant architecture to experimental or natural drought (Ambrose, Sillett, & Dawson, ; Dayer et al, ; Egea et al, ; Prendin, Mayr, Beikircher, von Arx, & Petit, ; Yue et al, ). Some studies also report plastic responses in hydraulic traits to short‐term drought, related to both hydraulic safety and hydraulic efficiency (Awad, Barigah, Badel, Cochard, & Herbette, ; Beikircher & Mayr, ; Prendin et al, ; Tomasella et al, ).…”

The fate of tropical forests under future climate change is dependent on the capacity of their trees to adjust to drier conditions. The capacity of trees to withstand drought is likely to be determined by traits associated with their hydraulic systems. However, data on whether tropical trees can adjust hydraulic traits when experiencing drought remain rare. We measured plant hydraulic traits (e.g. hydraulic conductivity and embolism resistance) and plant hydraulic system status (e.g. leaf water potential, native embolism and safety margin) on >150 trees from 12 genera (36 species) and spanning a stem size range from 14 to 68 cm diameter at breast height at the world's only longrunning tropical forest drought experiment. Hydraulic traits showed no adjustment following 15 years of experimentally imposed moisture deficit. This failure to adjust resulted in these drought-stressed trees experiencing significantly lower leaf water potentials, and higher, but variable, levels of native embolism in the branches. This result suggests that hydraulic damage caused by elevated levels of embolism is likely to be one of the key drivers of drought-induced mortality following long-term soil moisture deficit. We demonstrate that some hydraulic traits changed with tree size, however, the direction and magnitude of the change was controlled by taxonomic identity. Our results suggest that Amazonian trees, both small and large, have limited capacity to acclimate their hydraulic systems to future droughts, potentially making them more at risk of drought-induced mortality.

“…Plant growth is restricted by a variety of environmental factors, and climate factors are the main factors for determining the large-scale distribution of plants [35][36]. In this study, to analyze the climatic suitability regionalization of A. arguta in China, we chose climatic factors and altitude factors as initial environmental variables.…”

The interaction between plants and climate is reflected in the adaptation of plants to climatic factors and the feedback of plants to climate [1-2]. Climate is the dominant factor affecting plant distribution. Climate is expressed in the fact that heat is the source of energy for plant life activities, and water is the basic component of plants and can affect plant physiological activities. Climate change will have a great impact on the growth, geographical distribution, diversity and richness of plants. In global climate change, the most important ecological factors influencing the plant-ecosystem are

“…Sampled subplots were set in the center of each plot. We focused on four functional traits, including plant height, specific leaf area (SLA), leaf dry matter content (LDMC), and leaf nitrogen content (LNC) because these traits related to different plant functional strategies [29,30]. The maximum plant height was measured using steel tape.…”

Plant functional traits can reflect the response and adaptation of plant species to environmental changes. However, how plant functional traits of dominant species respond to the fencing, water and nitrogen additions in a sandy grassland ecosystem is still unclear. Here, a manipulative field experiment was conducted to investigate the effects of fencing, water and nitrogen addition on the functional traits of four dominant species (Pennisetum centrasiaticum, Cleistogenes squarrosa, Chenopodium acuminatum and Salsola collina) in Horqin sandy grassland. The results showed that nitrogen addition had a significant effect on plant height, specific leaf area (SLA), leaf nitrogen content (LNC), and leaf dry matter content (LDMC). Nitrogen addition increased plant height for C. squarrosa as well as SLA for P. centrasiaticum and S. collina, while reducing plant height for P. centrasiaticum and LDMC for S. collina. Also, nitrogen addition increased LNC for the four dominant species. Water addition reduced LDMC in grazing treatment, as well as plant height in fencing and nitrogen addition treatments. Compared to control treatment, nitrogen addition increased the strength of negative associations of LDMC with plant height and LNC. The results suggest that nitrogen addition plays an important role in determining the growth of the four dominant species, and water addition increases the competition of resource use among species in fencing and nitrogen addition treatments. Plants in sandy grassland can mediate the key functional traits to cope with alterations of water and nitrogen under the future global change scenarios.
