Natural Selections: Unusual pollinators
Paul Smiths, NY, Apr 18, 2013 — Everyone is familiar with how bees and insects distribute pollen from one flower to another, but that's not the only way to get the job done. Some night-blooming plants are pollinated by bats, when bright floral colors are invisible. And hummingbirds might just get their nectar without picking up any pollen. Dr. Curt Stager and Martha Foley discuss the unusual strategies some plants can use to attract and hold the interest of the unusual animals that pollinate them. Go to full article

Paul Smiths, NY, Mar 21, 2013 — Martha Foley mows her lawn just before the dandelions go to seed, hoping to keep their numbers down, but there's another whole crop right behind--why?

Natural Selections: Ancient Adirondacks
Paul Smiths, NY, Mar 14, 2013 — "Old as the hills" is a relative term.
