A climate-mediated ecological cascade leads to salmonellosis outbreaks in the United States. Temperature differences in successive summers are associated with differences in tree cone production in high-elevation and high-latitude forests (Top row), such that a warm summer followed by a cold summer is associated with a drop in cone production the following year (Top Right panel). Cone production is negatively associated with facultative bird migrations (irruptions) of eight seed-eating species (Middle row), such that when cone numbers are low, birds are more likely to irrupt in large numbers (Middle row, Right panel). When irruptions of pine siskins (S. pinus) occur, more songbirds are often found infected with, or dead from, salmonellosis (Bottom Right panel).

How does a single cuckoo species evolve eggs that mimic those of many different hosts?

In a new Science study, researchers report genomic data that reveal a complex geographic mosaic of cuckoo-host coevolution.

Our new @science.org paper is out! Cuckoos and hosts are locked in a coevolutionary arms race over egg mimicry.

But how are these egg types inherited, and could this drive speciation? We sequenced hundreds of genomes to find out!
