Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Country	Netherlands	96 H Index
Subject Area and Category	Environmental Science Environmental Engineering Management, Monitoring, Policy and Law Nature and Landscape Conservation
Publisher	Elsevier BV
Publication type	Journals
ISSN	09258574
Coverage	1992-ongoing
Scope	The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or constructing ecosystems. It is meant to serve as a bridge between ecologists and engineers, as ecotechnology is not wholly defined by either field. The journal will be read and contributed to by applied ecologists, environmental scientists and managers and regulators, natural resource specialists (e.g. foresters, fish and wildlife specialists), environmental and civil engineers, agroecologists, and landscape planners and designers. The journal is also for engineers who, as a result of training and/or experience in biological and/or ecological sciences, are involved in designing and building ecosystems. (source)
