Theory provides more precise estimates of large-area biodiversity
Published July 9, 2009, 3:58 pm, UC Berkeley NewsCenter
The Census Bureau is good at profiling the U.S. population by sampling small groups of people, but biologists lack a good way to estimate the richness of life in large areas based on small-area studies. Ecologist John Harte has developed a new theory that does a much better job predicting biodiversity in large biomes and could be a boon to conservation biologists.
Theory provides more precise estimates of large-area biodiversity
Published July 9, 2009, 2:35 pm, PhysOrg
Ask biologists how many species live in a pond, a grassland, a mountain range or on the entire planet, and the answers get increasingly vague. Hence the wide range of estimates for the planet's biodiversity, predicted to be between 2 million and 50 million species.
New theory gives more precise estimates of large-scale biodiversity
Published July 9, 2009, 2:29 pm, EurekAlert!
( University of California - Berkeley ) The Census Bureau is good at profiling the US population by sampling small groups of people. Biologists, however, lack a good theory of how to estimate the richness of life in large areas like the Amazon from small-plot studies. UC Berkeley ecologist John Harte has applied information theory to develop a new and robust theory that does a much better job ...

Rare Siberian tigers face potential genetic bottleneck
Published July 8, 2009, 11:42 am, Scientific American
It's been a long century for the Amur, or Siberian, tiger (Panthera tigris altaica), the largest of the six remaining tiger subspecies. Once hunted nearly to extinction, just 50 tigers remained when Russia protected the species in 1947. Despite that protection, illegal poaching soon dropped that number to as few as 20. But enforcement and careful conservation over the ensuring decades have done ...
