Estimates of population sizes forms many aspects of conservation policy and planning, including IUCN Red List decisions and CITE decisions on trade in endangered species. For population size estimates to be useful to decision-makers, it is critical that they are made using appropriate methods and that when reported, sources of uncertainty and systematic bias are discussed and accounted for in the conclusions.

Conservation and historical biogeography: How did the mountain chicken frog get to the Caribbean?
Leptodactylus fallax, commonly known as the mountain chicken frog, is a large terrestrial frog currently found on two islands in the Caribbean. Habitat destruction, overhunting and disease outbreaks have contributed to declining population numbers. In order to identify appropriate conservation strategies, the historic geographic distribution of this frog must first be determined. Because no archeological evidence...

Invasive weed risk assessment of three potential bioenergy fuel species
Bioenergy crops are potential renewable sources of bio-diesel which have low emission profiles, environmentally beneficial, and capable of substituting petro-diesel. However, since most of them are introduced or are not native, it is essential to reduce the ecological and economic consequences of invasive pest introductions and the potential invasiveness of species not yet introduced. The Australian Weed Risk Assessment...
