Scientists who work with live organisms often have to move them between locations. This requires knowing what conditions creatures can tolerate well, and also can involve some unusual packing challenges. Here three researchers explain how they transport butterflies, sea turtles and endangered frogs safely between labs and the outdoors.
For their first 100 million years on planet Earth, our mammal ancestors relied on the cover of darkness to escape their dinosaur predators and competitors. Only after the meteor-induced mass extinction of dinosaurs66 million years ago could these nocturnal mammals explore the many wondrous opportunities available in the light of day.
The amount of leopards in South Africa is declining rapidly, explicitly in the north of the country. In the past 10 years the leopard population has dropped as much as 66% near the border with Zimbabwe. According to Royal Society Open Science there are barely 4500 wild leopards left in the whole of South Africa.
About 45 percent of the U.S. is relatively undisturbed by human beings. These natural areas, such as the forest patches of the Southeast, provide homes for many species today. But those species will undoubtedly need to move in the near future as temperatures continue warming and precipitation shifts. Is there some way we can plan for and aid species to adapt as the climate changes?
