Spring is coming early in 3/4 of national parks, according to a new study. Awesome? Not so much. As flowers bloom earlier every year, it’s disrupting the link between the wildflowers and the arrival of birds, bees, and butterflies that feed on and pollinate the flowers. In Shenandoah, an earlier spring is giving invasive plants a head start, and they’re displacing native wildflowers, leading to costly management issues.
Before the 1960s almost everything about living openly as a lesbian, gay, bisexual, or transgender (LGBT) person was illegal. New York City laws against homosexual activities were particularly harsh. The Stonewall Uprising on June 28, 1969 is a milestone in the quest for LGBT civil rights and provided momentum for a movement.
Vine Creek Ranch at Death Valley National Park. Steady drought and record summer heat make Death Valley a land of extremes. Towering peaks are frosted with winter snow. Rare rainstorms bring vast fields of wildflowers. Lush oases harbor tiny fish and refuge for wildlife and humans. Despite its morbid name, a great diversity of life survives in Death Valley.
Located 2,600 miles southwest of Hawaii, the National Park of American Samoa is the most remote unit of the National Park System and the U.S. National Park south of the Equator. The Park spreads across three islands, 9,500 acres of tropical rainforest, and 4,000 acres of ocean, including coral reefs. While remote, the islands of American Samoa, true to the meaning of the word Samoa (Islands of Sacred Earth), are welcoming and offer beautiful landscapes and centuries of culture and history.
David Lawrence is a Ph.D. student in the School of Aquatic and Fishery Sciences at the University of Washington. His current research investigates the influence of climate change and land-use alteration on the spread and potential impacts of non-native fishes on native fishes in rivers of the Northwest. Climate and land-use related stream warming can have detrimental effects on ecosystems by facilitating range expansions of warm-water invasive fishes such as smallmouth bass, while reducing the thermally suitable habitat for cold-water native species, such as stream-rearing Chinook salmon. His work will be used to identify stream areas to either conserve or restore to reduce the range expansion of invasive fishes and assuage their predicted impacts. Prior to beginning his doctorate, David worked as a research scientist at the University of Washington and the Louisiana Universities Marine Consortium. He earned his MA at Boston University and BS at Benedictine University in Illinois.
