The almond and peach trees genomes shed light on the differences between these close species

An international team led by researchers has sequenced the genome of the almond tree and compared it to that of its closest relative, the peach tree. The most substantive differences between these species, so closely related in terms of evolution, are accounted for by the variation created by mobile genetic elements. The results provide some unique insights into the recent evolution of both species and will be key tools in their genetic improvement.

Aerosols from coniferous forests no longer cool the climate as much

Emissions of greenhouse gases have a warming effect on the climate, whereas small airborne particles in the atmosphere, aerosols, act as a cooling mechanism. That is the received wisdom in any case. However, new research can now show that the tiniest aerosols are increasing at the expense of the normal sized and slightly larger aerosols — and it is only the latter that have a cooling effect.

Bee biodiversity barometer on Fiji

The biodiversity buzz is alive and well in Fiji, but climate change, noxious weeds and multiple human activities are making possible extinction a counter buzzword. Just as Australian researchers are finding colourful new bee species, some of them are already showing signs of exposure to environmental changes.

Surrogate-reared sea otters helped restore threatened population

The population of threatened southern sea otters in Elkhorn Slough, an estuary in Central California, has made a significant comeback as a result of Monterey Bay Aquarium's Sea Otter Program. A newly-published study documents 15 years of research showing how the program helped restore the population in the coastal estuary.
