Seasonal dynamics in carbon dioxide fluxes of the herbaceous layer of a moist Kenyan savannah
(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2014)Strong seasonal variability in African carbon source/sink relationship is considered the continent’s most significant contribution to the global carbon cycle. Alternating dry and wet periods dictate ecosystem carbon exchange ... -
Treatment of tea industry wastewater using a combined adsorption and advanced oxidation process
(International Conference on Sustainable Research and Innovation, 2014)Tea, produced from the evergreen plant, Camellia Sinensis, is the most widely consumed beverage in the world after water. Although tea processing has now diversified into various speciality end products such as instant, ... -
Effect of grazing and canopy on Mediterranean ecosystem functioning: Carbon dioxide exchange and the dynamics of carbon and nutrient pools
(EGU General Assembly, 2010)Mediterranean ecosystems occupy less than 5 % of the Earth's surface, yet they contain about 20 % of the world's flora, including important components in grasslands. In this study, important ecosystem functions (CO2 exchange, ... -
Canopy transpiration and stomatal responses to prolonged drought by a dominant desert species in central Asia
(MDPI AG, Basel, Switzerland, 2017)In arid and semiarid lands, canopy transpiration and its dynamics depend largely on stomatal sensitivity to drought. In this study, the sap flow of a dominant species, Haloxylon ammodendron growing in Central Asian deserts, ... -
Higher assimilation than respiration sensitivity to drought for a desert ecosystem in Central Asia
(Elsevier, 2017)Responses of ecosystem assimilation and respiration to global climate change vary considerably among terrestrial ecosystems constrained by both biotic and abiotic factors. In this study, net CO2 exchange between ecosystem ... -
Tree growth and water-use in hyper-arid Acacia occurs during the hottest and driest season
(Springer-Verlag GmbH Germany, 2018)Drought-induced tree mortality has been recently increasing and is expected to increase further under warming climate. Conversely, tree species that survive under arid conditions might provide vital information on successful ... -
Seed dispersal by Tana River mangabeys in fragmented gallery forests
(SciRes., 2012)Data collected on a free ranging group of Tana River mangabeys (Cercocebus galeritus) indicates that this endangered primate species, which has previously been regarded as a seed predator, plays an important role in seed ... -
Transpirational water use and its regulation in the mountainous terrain of S. Korea
(American Geophysical Union, 2009)Quantifying water use by forests growing on complex mountainous terrain is difficult and understanding of controls on water use by these forests a challenge. Yet mountains are crucial as water towers and better understanding ... -
A prospective observational description of frequency and timing of antenatal care attendance and coverage of selected interventions from sites in Argentina, Guatemala, India, Kenya, Pakistan and Zambia
(BMC, 2015)The Global Network for Women’s and Children’s Health Research is one of the largest international networks for testing and generating evidence-based recommendations for improvement of maternal-child health in resource-limited ... -
Spatial heterogeneity in stand characteristics alters water use patterns of mountain forests
(2017)Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management ... -
A global synthesis of the effects of diversified farming systems on arthropod diversity within fields and across agricultural landscapes
(WILEY, 2017)Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management ... -
On necessary and sufficient conditions for rationality of operator norm bounds in measure spaces
(2016-11)Norm bounds are useful properties of operators with interesting applications in operator algebras and quantum mechanics. Rationality of these norm bounds is very important in the study of operators in measure spaces. As a ... -
The norm attainability of some elementary operators

Soil water availability and capacity of nitrogen accumulation influence variations of intrinsic water use efficiency in rice
(Elsevier, 2016)Leaf intrinsic water use efficiency (WUEi) coupling maximum assimilation rate (Amax) and transpirable water lost via stomatal conductance (gsc) has been gaining increasing concern in sustainable crop production. Factors ... -
Patterns of CO2 exchange and productivity of the herbaceous vegetation and trees in a humid savanna in western Kenya
(Springer Science+Business Media Dordrecht, 2015)Factors governing the dynamics between woody and herbaceous vegetation in the savanna are of ecological interest since they determine ecosystem productivity and stability. Field measurements were conducted in a humid savanna ... -
The Afro-alpine dwarf shrub Helichrysum citrispinum favours understorey plants through microclimate amelioration
(Taylor & Francis, 2015)Background: Positive plant–plant interactions similar to specialised plant growth forms are potential strategies to overcome the environmental harshness of Afro-alpine ecosystems. However, knowledge about plant–plant ... -
Supplement understanding of the relative importance of biophysical factors in determination of photosynthetic capacity and photosynthetic productivity in rice ecosystems
(Elsevier, 2016)Extensive variation in gross primary production (GPP) among growing seasons in rice ecosystems, which has previously been reported, may be caused by a number of biophysical factors. Two field-based studies, one on Oryza ... -
Quantification of ecosystem carbon exchange characteristics in a dominant subtropical evergreen forest ecosystem
(Korean Meteorological Society and Springer Netherlands, 2012)CO2 fluxes were measured continuously for three years (2003–2005) using the eddy covariance technique for the canopy layer with a height of 27 m above the ground in a dominant subtropical evergreen forest in Dinghushan, ... -
Water use by a warm-temperate deciduous forest under the influence of the Asian monsoon: contributions of the overstory and understory to forest water use
(Elsevier, 2013)The warm temperate deciduous forests in Asia have a relatively dense understory, hence, it is imperative that we understand the dynamics of transpiration in both the overstory (E O) and understory (E U) of forest stands ... -
Conditional variations in temperature response of photosynthesis, mesophyll and stomatal control of water use in rice and winter wheat
(2016)Environmental responses of photosynthesis and CO2 diffusive conductance as fundamental information for photosynthesis-transpiration coupled model have been increasingly concerned while are still research areas with unanswered ...
