Ecotourism as a strategy for achieving biodiversity conservation often results in limited conservation impact relative to its investment and revenue return. In cases where an ecotourism strategy has been used, projects are frequently criticized for not providing sufficient evidence on how the strategy has reduced threats or improved the status of t...
Article
Many remaining wild tiger populations persist in small numbers at sites where densities are less than half of their estimated carrying capacity and will continue to decline if not protected from poaching. Although law enforcement is frequently used to protect tigers and their prey, the conditions under which enforcement is likely to be effective in...

Data
Significant zoonoses by taxonomic family. Diseases considered as significant zoonoses are based on Pavlin et al. [24], (marked P in table below), and Levison et al. [23] (marked L in the table). Significant zoonoses jointly reported by Pavlin et al. [24] and Levison et al. [23] are marked with a P. Due to the non-host specificity of many infectious...

Phayre's leaf monkey Trachypithecus phayrei had fewer confirmed 1990s records in Lao PDR than any other monkey known from the country, suggesting a general rarity there. This review collates records, historical and recent, to evaluate its national conservation status. Although in no area have surveyors regularly and readily seen the species, record...
Article
Full-text available
Although considerable effort and resources have been dedicated to biodiversity conservation over the last three decades, the effectiveness of these conservation actions is still frequently unclear. Thus, practitioners are being called on to be ever more strategic in their use of often limited resources available for the scale of the work required....
