In an article published in World Watch magazine in 2004, Mac Chapin critiqued the work and style of functioning of three big conservation NGOS -- World Wildlife Fund (WWF), Conservation International (CI), and The Nature Conservancy (TNC) -- , especially in relation to their neglect indigenous peoples living within their areas of work. Based on … Continue reading Revisiting Chapin 2004

Revisiting Pauly et al. 1998
In a paper published in Science in 1998, Daniel Pauly, Villy Christensen, Johanne Dalsgaard, Rainer Froese and Francisco Torres Jr., using the Food and Agriculture Organisation's (FAO's) global fisheries catch data, showed that the mean trophic level had declined over the period of 1950 to 1994. In other words, fisheries, over this period, was moving … Continue reading Revisiting Pauly et al. 1998
Revisiting Şekercioğlu et al. 2002
In a paper published in PNAS in 2002, Çağan Şekercioğlu, Paul Ehrlich, Gretchen Daily, Deniz Aygen, David Goehring and Randi Sandi showed. using data from forest fragments in Costa Rica, that the ability to move through the deforested matrix was the best predictor of persistence of understory insectivorous birds in small forest fragments. Bird diets, … Continue reading Revisiting Şekercioğlu et al. 2002
Revisiting Likens et al. 1970
In a study published in Ecological Monographs in 1970, Gene Likens, F. Herbert Bormann, Noye Johnson, Don Fisher and Robert Pierce compared nutrient budgets between a control forested catchment and a catchment that was deforested and regrowth prevented for two years through the application of herbicide. Likens and colleagues demonstrated that this manipulation caused changes … Continue reading Revisiting Likens et al. 1970
Revisiting Ostrom & Nagendra 2006
In a paper published in PNAS in 2006, Elinor Ostrom and Harini Nagendra synthesized the findings of a long-term research program aimed at understanding how institutional factors affect forests managed under different kinds of tenure. Bringing together satellite images, socio-ecological studies in the field, and laboratory experiments of human behaviour, Ostrom and Nagendra showed that … Continue reading Revisiting Ostrom & Nagendra 2006
Revisiting Soule 1985
In a paper published in Bioscience in 1985, Michael Soule laid out his vision for a new discipline called Conservation Biology to "provide principles and tools for preserving biological diversity". Soule envisioned Conservation Biology as a "crisis discipline" in which "one must act before knowing all the facts", using a "mixture of science and art", … Continue reading Revisiting Soule 1985
Revisiting Stachowicz et al. 1999
In a paper published in Science in 1999, Jay Stachowicz, Robert Whitlach and Richard Osman showed, using experimental communities of sessile marine invertebrates that invasion success was lower in more species rich communities. The like reason for this pattern was that space, which was the limiting resource in the system, was more fully and efficiently … Continue reading Revisiting Stachowicz et al. 1999
Revisiting Carvalho & Vasconcelos 1999
In a paper published in Biological Conservation in 1999, Karine Carvalho and Heraldo Vasconcelos examined the effects of forest fragmentation on litter-dwelling ants in Central Amazonia. Their results suggested that litter ant communities were structured both by edge and isolation effects in these fragments. Twenty-one years after the paper was published, I asked Karine Carvalho … Continue reading Revisiting Carvalho & Vasconcelos 1999
Revisiting Coulson et al. 2001
In a paper published in Science in 2001, Tim Coulson, Edward Catchpole, Steve Albon, Byron Morgan, Josephine Pemberton, Tim Clutton-Brock, Mick Crawley, and Bryan Grenfell examined the effect of density, climate and demography on population fluctuations in Soay sheep on the St. Kilda islands in the United Kingdom. Coulson and colleagues' found that age and … Continue reading Revisiting Coulson et al. 2001
Revisiting Torchin et al. 2003
In a paper published in Nature in 2003, Mark Torchin, Kevin Lafferty, Andrew Dobson, Valerie McKenzie and Armand Kuris provided evidence to suggest that reduced parasite load in their introduced range might contribute to an exotic species' invasive success. Using data from 26 exotic species from a variety of taxa, Torchin and colleagues found that … Continue reading Revisiting Torchin et al. 2003
