Introduction:Aquatic Science is the multidisciplinary study of aquatic systems,encompassing both freshwater and marine systems. Scientificinvestigations within this field often examine the human impact on andinteraction with aquatic systems and range in scale from the molecularlevel of contaminants to the stresses on entire ecosystems The internationalquarterly journal Aquatic Ecology has succeeded the `Netherlands Journalof Aquatic Ecology" from Springer Netherlands. Journal has now mostinfluential journal in Aquatic Science with an impact factor of 1.41.Aquatic Ecology publishes peer-reviewed, original papers relating to theecology of fresh, brackish, estuarine and marine environments. Papers onfundamental and applied novel research in both the field and the laboratorywill be included in the journal.
Objectives of the study: To find out the year, volume and issue wise distribution of articles. To find out the authorship pattern of the contributions. To find out the proportion of single v/s multi authored papers. To find the degree of collaboration in the field of Aquatic Science. To find out the research productivity count of the contributions on thebasis of geographical distribution.
Methodology:For the present study “Aquatic Ecology” (2008-20012) has been used as thesource journal. To meet the objectives of the present study the necessary datawere collected by online version of journal through Springer publications viahttp://link.springer.com/journal/10452 website. All the required data likenumber of authors, number of papers, contributions in each volume,geographical location of authors at international level were tabulated. The datawas then subjected to analysis as per the objectives of the study. Theauthorship pattern has been analysed by using K. Subramaniam’s degree ofcollaboration in quantitative terms. All the data were subsequently examined,observed, analysed and tabulated for making observations.
Scope and Limitations of the Study:In this study an attempt has been made to analysethe contributions in 20 issues of 5 volumes of theAquatic Ecology journal during year from 2008 to2012.
