At the species level, plants can respond to climate changes by changing their leaf traits; however, there is scant information regarding the responses of morphological, physiological and anatomical traits of plant functional types (PFTs) to aridity. Herein, the leaf traits of five PFTs representing 17 plant species in temperate grasslands were examined along a large-scale aridity gradient in northeastern China. The results show that leaf thickness in shrubs, perennial grasses and forbs increased with heightened aridity. Trees increased soluble sugar content, but shrubs, perennials and annual grasses enhanced proline accumulation due to increasing aridity. Moreover, vessel diameter and stomatal index in shrubs and perennial grasses decreased with increasing aridity, but stomatal density and vascular diameter of five PFTs were not correlated with water availability. In conclusion, divergences in adaptive strategies to aridity among these PFTs in temperate grasslands were likely caused by differences in their utilization of water resources, which have different temporal and spatial distribution patterns. Leaf traits of shrubs and perennial grasses had the largest responses to variability of aridity through regulation of morphological, physiological and anatomical traits, which was followed by perennial forbs. Trees and annual grasses endured aridity only by adjusting leaf physiological processes.

“…Foliar [N] and C:N ratio was determined using a CHN analyser (LECO TruSpec Micro, LECO Corporation, St. Joseph, MI, USA). Total nonstructural carbohydrates (TNC) were extracted and analysed for soluble sugars using a modified anthrone method (Ebell 1969), and starch was enzymatically quantified on the residual pellet (Megazyme, Bray, Co. Wicklow, Ireland). TNC was calculated as the sum of soluble sugars and starch.…”

Responses of leaf beetle larvae to elevated [CO2] and temperature depend on Eucalyptus species

It is essential to understand the combined effects of elevated [CO2] and temperature on insect herbivores when attempting to forecast climate change responses of diverse ecosystems. Plant species differ in foliar chemistry, and this may result in idiosyncratic plant-mediated responses of insect herbivores at elevated [CO2] and temperature. We measured the response of the eucalypt leaf beetle Paropsis atomaria (Coleoptera: Chrysomelidae) feeding on Eucalyptus tereticornis and Eucalyptus robusta. Seedlings were grown at ambient (400 µmol mol(-1)) or elevated (640 µmol mol(-1)) [CO2] and ambient (26/18 °C day/night) or elevated (ambient + 4 °C) temperature in a greenhouse for 7 months. Larvae fed on flush leaves from egg hatch to pupation while being directly exposed to these conditions. Elevated [CO2] reduced foliar [N] and [P], while it increased total nonstructural carbohydrates and the C:N ratio. Elevated temperature increased foliar [N] in E. robusta but not E. tereticornis. Plant-mediated effects of elevated [CO2] reduced female pupal weight and increased developmental time and leaf consumption. Larval survival at elevated [CO2] was impacted differently by the two host plant species; survival increased on E. robusta while it decreased on E. tereticornis. Elevated temperature accelerated larval development but did not impact other insect parameters. We did not detect a CO2 × temperature interaction, suggesting that elevated temperature as a combined direct and plant-mediated effect may not be able to ameliorate the negative plant-mediated effects of elevated [CO2] on insect herbivores. Our study highlighted host-plant-specific responses of insect herbivores to climate change factors that resulted in host-plant-specific survival.

The effects of dehydration and subsequent rehydration on photosynthetic parameters and carbon reserves were investigated in the resurrection plant Reaumuria soongorica. Dehydration was imposed by withholding water and covering plants with a PVC sheet when it rained, over a period of 53 days, by which time all leaves had been shed. Thereafter, plants were watered at 7-day intervals. The diurnal course of the net photosynthetic rate (Pn) was bimodal under well-watered conditions. After a period of withholding water, the second peak disappeared, and Pn, instantaneous water use efficiency (WUE), stomatal conductance (gs) and intercellular CO 2 concentration (Ci) decreased, but sugar, starch and non-structural carbohydrate (NSC) reserves increased. It was concluded that under the conditions of high temperature and dehydration, the reduction of Pn should be mainly attributed to gs. On rehydration Pn, gs, Ci and WUE increased slightly in the stem. Accompanying new leaf production, carbon reserves in the stem decreased. This indicated that carbon reserves in the stem have two important ecological roles, survival during dormant periods and support of vegetative regrowth following rehydration.
