Biotropica’s Greatest Hits (Part 2)

Monday I posted the list of Biotropica‘s most cited articles, but there’s a catch – the longer papers have been published, the more citations they can accumulate. An alternative way to present “most cited” is by correcting for article age, and showing number of citations per year. This results in a different list of “most cited” papers, with one notable exception.  Any guesses?  The picture below gives you a hint.

Here they are. The Top 5 when correcting for time since publication (i.e., total citations per year as of June 2013)

#5  Corlett, R. T. 2007. The impact of hunting on the mammalian fauna of tropical Asian forests. Biotropica 39: 292-303. (N = 12.9 citations yr-1)

#4 Chazdon, R. L., et al. 2009. Beyond Reserves: A Research agenda for conserving biodiversity in human-modified tropical landscapes. Biotropica 41: 142-153. (N = 14.7 citations yr-1)

#3  Peres, C. A., and E. Palacios. 2007. Basin-wide effects of game harvest on vertebrate population densities in Amazonian forests: Implications for animal-mediated seed dispersal. Biotropica 39: 304-315.  (N = 14.8 citations yr-1)

#2 Wright, S. J., and H. C. Muller-Landau. 2006. The future of tropical forest species. Biotropica 38: 287-301. (N = 17.7 citations yr-1)

#1  Oliveira-Filho, A. T., and M. A. L. Fontes. 2000. Patterns of floristic differentiation among Atlantic forests in southeastern Brazil and the influence of climate. Biotropica 32: 793-810. (N = 22.7 citations yr-1)

Several things really struck me about this list. The first was the unlike the “total citations” list, four of the five papers are conservation-related. This really says something about the upsurge in conservation-related research and Biotropica‘s role in publishing fundamental work in that area.  The second is that the most cited paper on this list is about Brazil’s Atlantic forests, rather than something from one of the historical hotspots of tropical research (e.g., La Selva, BCI). The last 10 years  have seen an upsurge in research from Brazil, much of it conducted in Brazil’s highly diverse and threatened Atlantic Forests. Oliveira-Filho and Fontes’ analysis has important implications not only for our understanding of how this hyper-diverse flora evolved, but emphasizes that it is necessary to consider geographic variation in diversity as we develop conservation strategies (geographic diversity that was under-appreciated prior to their study).
