Dynamics of metal uptake and depuration in a parasitized cyprinid fish (Rastrineobola argentea)
(Elsevier, 2012)Infestation of fish by endoparasites may potentially influence metal uptake and elimination by the host. We quantified the metal uptake rate constant (ku) and efflux rate constants (ke) of radiolabeled Cd and Co in the ... -
Larviciding potency of water and ethanol extracts of Phytolacca dodecandra (L’ Herit) on Anopheles gambiae (Diptera: Culicidae)
(BioPublishe, 2015)Introduction: Plant extracts are an attractive target for search of effective malaria vector control agents. The reason for this is that they present a cost effective, target specific and bio-degradable insecticides. The ... -

A comparison of CO2 fluxes via eddy covariance measurements with model predictions in a dominant subtropical forest ecosystem
(Copernicus Publications, 2009)CO2 fluxes were measured continuously for twelve months (2003) using eddy covariance technique at canopy layer in a dominant subtropical forest in South China. Our results showed that daytime maximum CO2 fluxes of the whole ... -
Responses of CO2 exchange and primary production of the ecosystem components to environmental changes in a mountain peatland
(Springer Science+Business Media, 2009)The complexity of natural ecological systems presents challenges for predicting the impact of global environmental changes on ecosystem structure and function. Grouping of plants into functional types, that is, groups of ... -
Analysing land cover and land use change in the Ruma National Park and surroundings in Kenya
(2017)The change of land use and land cover (LULC) is often driven by the growth of human population. In the Lambwe valley, Kenya, the most important reason for accelerated settlement in the last decades was the control of the ... -
Overcoming the Challenges of Estimating Water Use in Temperate, Mixed Deciduous Forest of S. Korea
(American Geophysical Union, 2009)About 80% of forests in Korea occur in mountainous regions and are composed of a rich diversity of mixed deciduous tree species. Mountains in this region receive more rainfall and act as fountains that supply fresh water ... -
Interactive influence of livestock grazing and manipulated rainfall on soil properties in a humid tropical savanna
(Springer Berlin Heidelberg, 2018)Purpose The effect of uncontrolled grazing and unpredictable rainfall pattern on future changes in soil properties and processes of savanna ecosystems is poorly understood. This study investigated how rainfall amount at ... -
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 ...
