Songbirds become disoriented by street lamps, plants adapt to the conditions near Chernobyl, a newly discovered spider spins gigantic webs with the strongest known biological material in the world, traffic light experiment shows promise of reducing emissions and easing traffic congestion and researchers discuss the Daily Show with Jon Stewart as an outlet for communication science to the public. Here are some of the latest stories in ecology for the second to last week in September.
Male jumping spiders (Phidippus clarus) size one another up before engaging in a fight—whether the aggression is based on rights to mating or territory—and in many cases, the pre-fight displays are sufficient to deter physical contact.

The females, on the other hand, are not nomads—they build nests from silk and leaves in which they wait while they draw closer to sexual maturity.
