Primary forests are irreplaceable for sustaining tropical biodiversity
It is found that biodiversity values were substantially lower in degraded forests, but that this varied considerably by geographic region, taxonomic group, ecological metric and disturbance type. Expand
Southeast Asian biodiversity: an impending disaster.
The looming Southeast Asian biodiversity disaster demands immediate and definitive actions, yet such measures continue to be constrained by socioeconomic factors, including poverty and lack of infrastructure. Expand
Synergies among extinction drivers under global change.
Estimates of extinction risk for most species are more severe than previously recognised and conservation actions which only target single-threat drivers risk being inadequate because of the cascading effects caused by unmanaged synergies. Expand
Most species are not driven to extinction before genetic factors impact them.

Differences in heterozygosity indicate lowered evolutionary potential, compromised reproductive fitness, and elevated extinction risk in the wild in threatened species. Expand
Genetics in conservation management: Revised recommendations for the 50/500 rules, Red List criteria and population viability analyses
How adequately genetic factors are currently incorporated into population viability analysis (PVA) models used to estimate minimum viable population sizes is assessed, and population size thresholds of the IUCN Red List criteria for threatened species that were derived from genetic considerations are related. Expand
Catastrophic extinctions follow deforestation in Singapore
Extrapolations of the observed and inferred local extinction data imply that the current unprecedented rate of habitat destruction in Southeast Asia will result in the loss of 13–42% of regional populations over the next century, at least half of which will represent global species extinctions. Expand
Estimates of minimum viable population sizes for vertebrates and factors influencing those estimates
The results of the simulations suggest that conservation programs, for wild populations, need to be designed to conserve habitat capable of supporting approximately 7000 adult vertebrates in order to ensure long-term persistence. Expand
Tropical turmoil: a biodiversity tragedy in progress
All is not well for biodiversity in the tropics. Despite recent debate over the extent of future tropical extinctions and the effectiveness of reserve systems, the continued disappearance of habitat,… Expand
Realistic levels of inbreeding depression strongly affect extinction risk in wild populations
In the stochastic computer projections, 12 diploid lethal equivalents of inbreeding depression (with purging) decreased median times to extinction by an average of 37%. Expand

Southeast Asia is a region of conservation concern due to heavy losses of its native habitats. In this overview, we highlight the conservation importance of Southeast Asia by comparing its degree of… Expand
