Leaching losses of nitrogen (N) from soil and atmospheric N deposition have led to widespread changes in plant community and microbial community composition, but our knowledge of the factors that determine ecosystem N retention is limited. A common feature of extensively managed, species-rich grasslands is that they have fungal-dominated microbial communities, which might reduce soil N losses a...
With continuous measurements of dissolved oxygen, temperature, irradiance, and wind speed, as well as frequent measurements of pH, oxidation-reduction potential, and algal chlorophyll, temporal dynamics and drivers of ecosystem metabolism in a large nutrient-rich shallow lake (Lake Taihu) are tested in this study. The results show that the dissolved oxygen concentrations in the lake fluctuate a...
Lactic acid bacteria (LAB) are widespread microorganisms which can be found in any environment rich mainly in carbohydrates, such as plants, fermented foods and the mucosal surfaces of humans, terrestrial and marine animals. In the human and animal bodies, LAB are part of the normal microbiota or microflora, the ecosystem that naturally inhabits the gastrointestinal and genitourinary tracts, wh...
many of the video processing algorithms cannot be implemented in real time on general computers, due to their computational complexity. for an efficient implementation, a custom hardware that can be reconfigured for the algorithm, is used. in this paper a new acceleration hardware based on fpga elements is proposed. this hardware can be adapted with the processing algorithm through fpga design ...
Abstract Global population growth rate accelerating earth ecosystem disturbance and increasing resource scarcity, malnutrition poverty. These events challenge socio-economic development of each country obligate scientific communities to develop such novel approaches overcome this burden, which not only provide a healthy diet but also engage people in setting up their own business. Therefore, mi...
Predicting climate change impact on ecosystem structure and services is one of the most important challenges in ecology. Until now, plant species response to climate change has been described at the level of fixed plant functional types, an approach limited by its inflexibility as there is much interspecific functional variation within plant functional types. Considering a plant species as a se...
Dioscorea species, known as “Yams,” belong to family Dioscoreaceae. This genus consists ofmore than 600 species distributed from Africa, Asia, the Caribbean’s South America, and theSouth Pacific islands. Their organoleptic properties make them the most widely used carbohydratefood and dietary supplements. The underground and/or aerial tubers represent valuable sources...
Self-organization of heterogeneous particle swarms is rich in its dynamics but hard to design in a traditional top-down manner, especially when many types of kinetically distinct particles are involved. In this chapter, we discuss how we have been addressing this problem by (1) utilizing and enhancing interactive evolutionary design methods and (2) realizing spontaneous evolution of self-organi...
Mobile Government Ecosystem is one of the emerging ecosystems in Iran. The purpose of this paper is to identify and analyze the structure and identifying the role of each of the key stakeholders of this ecosystem. In order to achieve this purpose, by studying the related literatures and the models presented in these literatures, a mobile government ecosystem conceptual model is proposed, where ...
[1] The Ecosystem Demography (ED) model was parameterized with ecological, forest inventory, and historical land use observations in an intensively managed, wetland-rich forested landscape in the upper midwest United States. Model results were evaluated against a regional network of eddy covariance flux towers and analyzed about the roles of disturbance, forest management, and CO2 fertilization...
