    Beauty drives orchids towards extinction

    At plant markets in Thailand, exquisite orchids are for sale. Those orchids are unlike the ones you can buy at many U.S. shops; many of them are rare species that were collected from the wild. Selling them is illegal.

    Could the dinos of ‘Jurassic World’ become invasive?

Still awed by the seemingly realistic, long-extinct animals, I started wondering: What would happen if they escaped the remote Pacific island where they had been created and made it to land?

    A summer challenge: Observe nature

    One morning in early April in St. Augustine, Fla., I went for a walk. My goal had been the beach, but I never made it that far. Near the house where I was staying, I passed a mudflat along the Mantanzas River, and I noticed the ground moving. But it wasn’t really the ground — there were thousands of tiny fiddler crabs dancing about in the sun. As I approached the crabs, they scuttled into...

    The secret behind the world’s largest seed and its sexually extravagant plant is good gutters.

    A prodigy among those seeds can weigh as much as 18 kilograms, about the weight of a 4-year-old boy. Yet the plant that outdoes the rest of the botanical world in the heft of its seed manages with below-poverty nutrition. Coco-de-mer palms (Lodoicea maldivica) are native to two islands...
