“…Other studies also showed an increase or no change in NEP under experimental warming (Johnson et al 2000;Marchand et al 2004;Luo 2007) temperature is less critical than other plant and ecosystem processes, such as shifted plant and microbial species composition (Peñuelas et al 2004(Peñuelas et al , 2007Zhang et al 2005;Harte et al 2006), changes in phenology and extension of growing seasons (Nemanti et al 2003;Cleland et al 2007;Sherry et al 2007), and altered nitrogen uptake and use efficiency (Rustad et al 2001;Melillo et al 2002;An et al 2005), in regulating terrestrial feedback to climate change.…”

Warming-stimulated plant biomass production, due to enhanced C 4 dominance, extended growing seasons, and increased nitrogen uptake and use efficiency, offset increased soil respiration, leading to no change in soil C storage at our site. However, biofuel feedstock harvest by biomass removal resulted in significant soil C loss in the clipping and control plots but was carbon negative in the clipping and warming plots largely because of positive interactions of warming and clipping in stimulating root growth. Our results demonstrate that plant production processes play a critical role in regulation of ecosystem carbon-cycle feedback to climate change in both the current ambient and future warmed world.

“…However, improvements in WUE may not suffice to compensate negative effects on soil moisture of increased evapotranspiration and reduced rainfall scenarios, particularly when feedbacks between elevated CO 2 , water availability and vegetation are taken into account [49]. Indeed, reductions in above-ground biomass with increased warming and drought in drylands have been widely documented [50][51][52][53]. The size and frequency of rainfall events modulate processes such as soil and ecosystem respiration [54,55], microbial activity [56] and plant physiology and primary productivity [57].…”

Drylands occupy large portions of the Earth, and are a key terrestrial biome from the socio-ecological point of view. In spite of their extent and importance, the impacts of global environmental change on them remain poorly understood. In this introduction, we review some of the main expected impacts of global change in drylands, quantify research efforts on the topic, and highlight how the articles included in this theme issue contribute to fill current gaps in our knowledge. Our literature analyses identify key under-studied areas that need more research (e.g. countries such as Mauritania, Mali, Burkina Faso, Chad and Somalia, and deserts such as the Thar, Kavir and Taklamakan), and indicate that most global change research carried out to date in drylands has been done on a unidisciplinary basis. The contributions included here use a wide array of organisms (from micro-organisms to humans), spatial scales (from local to global) and topics (from plant demography to poverty alleviation) to examine key issues to the socio-ecological impacts of global change in drylands. These papers highlight the complexities and difficulties associated with the prediction of such impacts. They also identify the increased use of long-term experiments and multidisciplinary approaches as priority areas for future dryland research. Major advances in our ability to predict and understand global change impacts on drylands can be achieved by explicitly considering how the responses of individuals, populations and communities will in turn affect ecosystem services. Future research should explore linkages between these responses and their effects on water and climate, as well as the provisioning of services for human development and well-being.

BARTOŠOVÁ, L., BAUER, Z., TRNKA, M., ŠTĚPÁNEK, P., ŽALUD., Z.: Climatic factors and their infl uence on onset and duration of phenological phases of chosen plants at locations south Moravia during 1961. Acta univ. agric. et silvic. Mendel. Brun., 2010 In this work phenological phases of three species -ramson (Allium ursinum L.), hawthorn (Crataegus oxya can tha L.) and oak tree (Quercus robur L.) were evaluated on two research plots Lednice and Lanžhot during 1961-2007. Both plots represent protected fl ood-plain forests with no forestry management. The aim of this work is to assess which meteorological parameters infl uence the most duration of phenophases, to analyse shi s of phenophase timing during the period 1961 to 2007 and to compare phenological and temperature trends in this period. The meteorological and phenological data processed by so ware AnClim and FenoClim. Results showed that maximum and mean temperature infl uenced the duration of phenophases most signifi cantly. The higher temperatures caused shortening of pheno pha ses and vice versa. Per 1°C temperature increas the given phenophase its length will decrease by 2.3 days in case of oak tree, by 0.8 days in the case of hawthorn and by 1.3 days in the case of ramson. The onset of phenophases has advanced by 9 to 10 days during the period of 47 years. phenology, temperature, climatic parameters, Allium ursinum, Quercus robur, Crataegus oxyacantha, climate change Podle poslední zprávy IPCC je fenologie považo-vána za pravděpodobně nejjednodušší nástroj, kterým je možné dokazovat změny ve vývoji rostlin a ži-vočichů v závislosti na vývoji klimatu (Rosenzweig et al., 2007). V posledních dvaceti letech se fenologie postupně přesunula do popředí zájmu a stala se nedílnou součástí vědních oborů, pomocí kterých je posuzována změna klimatu. Je to z části proto, že reakce fenologických projevů druhů, zvláště rostlin, na zvyšující se teplotu je velmi silná a odezva na mě-nící se klima je zcela evidentní (Sparks et al
