Why do ecologists search for co-authorships? Patterns of co-authorship networks in ecology (1977–2016)
- 268 Downloads
Here, the pattern of co-authorship among ecologists was evaluated using a network approach that was built using four time periods (1977–1986, 1987–1996, 1997–2006, and 2007–2016). Furthermore, four potential explanations (geographic distance, word similarity, reputation asymmetry, and country development) for this pattern were evaluated. Distance and reputation asymmetry effects on collaboration have decreased in recent decades, whereas word similarity was a good predictor in recent decades. Of interest, country development was not a good predictor of co-authorship among ecologists.
