Sunday, July 20th, 2014, marked the 45th anniversary of the day the world stood still and watched astronauts Neil Armstrong and Edwin "Buzz" Aldrin land on the surface of the Moon. There is no question that the partnership between NASA and the USGS was crucial to the Apollo program's accomplishments.

This webinar was conducted as a part of the National Climate Change and Wildlife Science Center's Climate Change Science and Management Webinar Series.

This time-lapse of Barter Island in Alaska during three summer months in 2014, shows the pack ice melting and the subsequent effects to the beach and permafrost cliffs from storms and summer temperatures. This camera sat on a fallen snow fence to capture storm events.

Time-lapse photo of a rainfall-induced runoff event at an edge-of-field surface site near Fort Wayne, Indiana, on May 10-11, 2016. Edge-of-field monitoring is used to assess the quantity and quality of agricultural runoff and evaluate the effectiveness of conservation practices that aim to reduce nutrient loss.

Imagine being a fragile seedling pushing through the earth and reaching for the sun — but constantly being smothered by strange grasses growing faster and taller than you are. That is the plight of the Island Phacelia (Phacelia insularis var.

Remnants of former ranching enterprises, feral horses can still be found on Santa Rosa Island, part of the remote and hauntingly gorgeous Channel Islands National Park off the coast of Los Angeles.

“Endangered” may sometimes seem like a vague term, but it is an unfortunately suited description for the Island Bush-Mallow (Malacothamnus fasciculatus var. nesioticus).
