This article discusses the appeal to infinite value in environmental decision making. We argue that invoking infinite values as a means of faithfully representing the worth of certain parts of the natural environment is a mistake. Infinite values have a number of theoretical and practical problems associated with them. For example, we show that invoking [...]

The findings indicated that the positive behavior of local communities towards conservation of biodiversity within Pendjari National Park was highly correlated with the current management strategy that involved more effectively local communities, the educational level of participants and their geographical origins. Participants’ perceptions of biodiversity conservation were strongly related to locally perceived benefits. Although 89% [...]

Statements of extinction will always be uncertain because of imperfect detection of species in the wild. Two errors can be made when declaring a species extinct. Extinction can be declared prematurely, with a resulting loss of protection and management intervention. Alternatively, limited conservation resources can be wasted attempting to protect a species that no longer [...]

We evaluated the applicability of Rapoport’s Rule (RR) to the marine bony fishes of the world. The biogeographical pattern predicted by RR has been the subject of a large number of studies, some supporting it and some not. In this exercise, we attempted to generate results free of biases from taxonomy or geographic scale. The [...]

Although recent biodiversity loss has been compared with cataclysmic mass extinctions, we still possess few indicators that can assess the extent or location of biodiversity loss on a global scale. The Convention on Biological Diversity (CBD) has mandated development of indicators that can meet the needs of monitoring biodiversity by 2010. To date, many indicators [...]

We estimate the probable number of flowering plants. First, we apply a model that explicitly incorporates taxonomic effort over time to estimate the number of as-yet-unknown species. Second, we ask taxonomic experts their opinions on how many species are likely to be missing, on a family-by-family basis. The results are broadly comparable. We show that [...]

In a recent blog post, Andy Revkin quotes Governor Christy Whitman on our current energy/environmental policy impasse (http://dotearth.blogs.nytimes.com/2010/07/14/senate-eyes-bush-plan-on-co2/). This is my reply to those thoughts. What Governor Whitman has discovered and is relating to us is the simple fact that the petrochemical/fossil fuel industries own the United States Congress on issues related to their activities, [...]
