For camouflaged animals, a quick dash is best to avoid detection

A hunting falcon flying over a field might not see a camouflaged rabbit hidden in the grass. But if that rabbit loses its nerve and runs, then the falcon will see its meal. Movement gives away even the best disguises. … Continue reading

Cooperative defense against disease may have helped insects evolve complex societies

The lifestyles of insects, such as bees and wasps, range from simple solitary arrangements to more recently evolved, highly complex family social structures. One major factor that allowed social complexity to evolve may have been insects’ ability to defend their … Continue reading

Models shift blame for Neanderthal extinction away from modern humans

Neanderthals vanished about 40,000 years ago, but the reasons for their demise remain shrouded in mystery and a source of debate among archaeologists. The timing coincides with the arrival of modern humans in Europe, which has led some researchers to … Continue reading

Pollen frozen in a glacier reveals the legacy of human impacts in the heart of the Inca Empire

The Illimani glacier sits between the urban sprawl of La Paz, Bolivia, on one side, and the roads and plantations of the Amazon basin on the other. It was no doubt a very different landscape some 550 years ago, when … Continue reading

By separating life stages, metamorphosis may circumvent harmful evolutionary tradeoffs

  There’s no guarantee evolution will bestow the best version of every trait. The benefits of one trait may impose a cost when an unfavorable trait, correlated genetically, comes along for the ride. In a recent study on wood frogs (Rana sylvatica) … Continue reading

Predators can harm rather than help biodiversity

  Rich biodiversity depends on the ability of species to coexist. And yet, ecologists are still grappling with the requisite mechanisms. Recent findings published in Nature suggest that predators might not be as helpful a driver of species coexistence as … Continue reading

Journal Club: Protozoan predators help pinpoint how evolution and ecology shape predator-prey dynamics

A hungry lynx bounds after a scampering hare. Occasionally the lynx secures its catch. Often, it doesn’t. For ecology students, this back and forth battle is the textbook example of an ecological process driving predator–prey population dynamics. The predator population … Continue reading

Journal club: A simple model to help identify which species might become invasive

Invasive species are a major driver of global biodiversity loss. Now researchers have developed a simple model that can quickly predict which species are likely to become established outside their native environment. The team recently reported in the Proceedings of … Continue reading
