Spatial synchrony occurs when properties measured in populations (e.g., species abundance), communities (species richness) or ecosystems (e.g., primary productivity) vary synchronously. Several studies have demonstrated synchrony of temporal dynamics in local population densities (Knops and Koenig 1998; Shanker and Sukumar 1999; Cattadori et al 1999; Liebhold et al 2004a). Other studies also revealed synchrony as … Read more
Abstract: Solar energy is viewed as clean and renewable source of energy for the future. So the use of Photovoltaic systems has increased in many applications. That need to improve the materials and methods used to harness this power source. There are two major approaches; sun tracking and maximum power point tracking. These two methods … Read more

In high school we have learned about that gene is the basic unit to control biological traits, genetic information is recorded biological procreation. Different information recorded in different genes, gene can be changed by modifying some or all of the features of an organism. After entering the university, after the completion of the study a … Read more
Synchrony is a significant and recurring result for different taxonomic resolutions at the present time series study. The synchrony of zooplankton populations have been detected in different types of ecosystems, both temperate (Rusak et al. 1999, 2002) and tropical (Caliman et al. 2010). The results obtained in this study and for several other groups of … Read more
