“…Sperlich et al (2015) showed differences in photosynthetic potentials and drought-tolerance in sunlit and shaded leaves of four Mediterranean trees. The significant impact of microclimate on transition processes to the generative phase of plant development was described by Bahuguna and Jagadish (2015). Next point is the study of the altitude impact on tree taxa distribution.…”

SUMMARYThe effect of altitude-associated environmental gradient on leaves metabolic features of Quercus robur L. (an oak) and Fraxinus excelsior L. (an ash) was investigated in the natural coastal forest at Bellegarde' International Biosphere Reserve in Steppe zone, Ukraine. Decrease in relative humidity contrary to increase in temperature and lighting under the forest canopy were observed on the river steep bank with altitudinal elevation from lower (52 m a.s.l.) to middle (74 m.), and upper (96 m). Responses of tree leaves photosynthetic and antioxidant systems to the environmental local changes were studied by measuring chlorophyll (Chl) content, as well as catalase and peroxidase activities. Decrease in Chl amount in the ash leaves at middle and upper altitudes (17 and 38% compared with lower), along with increase (8% and 13%, respectively) in the oak leaves was found out. Chl content was determined to correlate with light, temperature, and humidity in both leaves of ash (respectively, r = -0.94, r = -0.92, r = 0.90) and oak (r = 0.95, r = 0.93, r = -0.90). Catalase activity grew with increasing altitude in leaves of ash (2 and 2.2 fold compared to lower altitude) and oak (1.2 and 1.4 fold) as well. Contribution of catalase to the total antioxidant enzymes activity enhanced in leaves of both species with increasing altitude. The results confirmed high sensitivity of steppe forest trees even to slight altitude-associated environmental deviations. Data obtained can be used to assess the adaptive potential of woody species to the climate changes aiming towards greater aridity traits and select tree species for planted forest creation as well.

“…This weakens our understanding of how ecosystems or even individual plants respond to changes in the environment. Furthermore, the long-term effects of environmental conditions, such as temperature and water availability, on phenological development are significant; environmental conditions greatly influence the initiation and duration of vegetative, reproductive, and maturation stages of plants (Bahuguna and Jagadish, 2015;Mickelbart et al, 2015). Due to the interrelatedness of physiological traits, plant developmental phases, and growth conditions, there is a need to gain a better understanding of the complexities of genotype-by-environment interactions.…”

“…On the landscape scale based on the satellite data, a similar conclusion that the warmer temperature accelerated the green‐up of grassland was also reported (Miao et al , ; Cheng et al , ; Wilsey et al , ). From the perspective of the plant physiology, the phenology could respond to the temperature sensitively because plants can precisely sense the absolute and gradual changes in the diurnal and seasonal temperatures with a wide array of thermosensors (Bahuguna and Jagadish, ). The impact of the temperature increase on phytohormone signalling and metabolic programming should be further investigated for a better understanding of the plant phenological response to temperature.…”

In a natural ecosystem or as climatic climax community, grassland is relatively dry with a strongly seasonal climate, and sensitive to climatic changes. Most of the previous studies used remote sensing data to investigate the phenological response of grassland to climate change, while ground‐based studies covering a large geographic area were limited. In this study, using the long‐term phenological data (1981–2012) of 16 herbaceous species observed at 20 stations in Inner Mongolia, China, we first investigated the trends in three spring phenophases, including the dates of bud‐burst, first leaf unfolding, and 50% of leaf unfolding. Subsequently, multiple linear regressions between phenophases and four climatic factors (spring temperature, soil moisture, chilling temperature, and insolation) were performed to determine the relative importance of each factor on the spring phenology. To validate the resulted regression coefficients, we developed a controlled environment to investigate the factors regulating the leaf unfolding time of one dominant species (Leymus chinensis). The results showed that the study area became warmer and drier from 1981 to 2012. However, the overall changes in spring phenophases were not apparent, as there was a similar proportion of significant earlier or later trends. Such phenological changes were driven by multiple climatic factors. The warmer temperature would advance the spring phenophases, while lower soil moisture would delay them. The impact of soil moisture was significant in the experimental data, but not significant in the observation data. In addition, leaf unfolding became faster when L. chinensis experienced more chilling days, but this effect was difficult to be detected in observation data due to the weak sensitivity of the leaf unfolding time to chilling days. These findings can help us to understand how the spring phenology of typical herbaceous species responds to multiple climatic factors under the background of climate change.
