  • When the dinosaurs died, so did forests -- and tree-dwelling birds - Sixty-six million years ago, the world burned. An asteroid crashed to Earth with a force one million times larger than the largest atomic bomb, causing the extinction of the dinosaurs. But dinosaurs weren't the only ones that got hit hard -- in a new study, scientists learned that the planet's forests were decimated, leading to the extinction of tree-dwelling birds.
  • Most comprehensive tree of life for malaria parasites - A new study puts forth the most comprehensive tree of life for malaria parasites to date. Among the researchers' findings is that the diverse malaria parasite genus Plasmodium (which includes those species that infect humans) is composed of several distantly related evolutionary lineages, and, from a taxonomic standpoint, many species should be renamed.
  • Long-term study reveals one invasive insect can change a forest bird community - Eastern hemlock forests have been declining due to a non-native insect pest. A new study presents some of the best data showing how the decline of a single tree species leads to the disappearance of birds specialized to them. The data also indicate birds associated with non-hemlock habitat features are spreading into former hemlock forests. A single insect species has led to a less diverse bird community across this landscape.

  • Phosphorus nutrition can hasten plant and microbe growth in arid, high elevation sites - Glacial retreat in cold, high-altitude ecosystems exposes environments that are extremely sensitive to phosphorus input, new research shows. The finding upends previous ecological assumptions, helps scientists understand plant and microbe responses to climate change and could expand scientists' understanding of the limits to life on Earth.
  • How do insects survive on a sugary diet? - Researchers show that bacteriocytes -- specific aphid cells that house the symbiotic bacteria -- have different DNA methylation patterns depending on what type of plant sap the aphid is consuming.
