Of the last two remaining populations of the recently discovered kipunji, one population shows evidence of past mating with baboons while the other does not, says a new study. The results may help to set conservation priorities for this critically endangered species, researchers say.

Identifying fossil plants can be tricky, however, when plant organs fail to be preserved. Researchers recently discovered abundant fossilized specimens of a conifer (previously known as "Libocedrus" prechilensis) found in Argentinean Patagonia. Characteristics of these fossils match those currently found only in tropical, montane New Guinea and the Moluccas. This discovery helps to explain the remarkable plant and insect diversity found in Eocene Patagonia.

The fig wasps are transporting pollen ten times further than previously recorded for any insect. The fig wasps travel these distances in search of trees to lay their eggs, which offers hope that trees pollinated by similar creatures have a good chance of surviving if they become isolated through deforestation.

To lessen the negative effects during the later life stage, scientists recommend partial or selection cuts to forests rather than completely removing trees from an area.

These fast-growing, pine-like trees were historically planted widely as ornamentals and along boulevards in south Florida, and are currently being proposed as a windbreak in citrus groves. However, the trees are frequently the tallest in the canopy and can be very damaging during storms and hurricanes.

This is shown in a new study. Phages appear to be better able to infect bacteria from the same small soil sample than bacteria from just a few centimeters away. Evolution can therefore restructure ecosystems on a very small scale.

So-called Earth system models, computer systems making predictions for the globe, estimate that this effect can be very large. However, new research results, based on measurements at hundreds of European forests, indicate that predicted effects by these models are overestimated because they ignore the limitation of nitrogen. It makes the current predictions by Earth system models more than twice as high as they most likely will be.
