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.
DOINews: New Paper on "Choosing and Using Climate-Change Scenarios for Ecological-Impact Assessments and Conservation Decisions"
Last edited 4/26/2016
A new paper, "Choosing and Using Climate-Change Scenarios for Ecological-Impact Assessments and Conservation Decisions" examines how to choose from myriad climate scenarios for things like impacts and/or vulnerability assessment. Jeremy Littell, Lead Research Scientist at the Alaska Climate Science Center, co-authored this research.
The guide to climate change scenario use addresses common misperceptions about the utility of climate scenarios for biological assessments and decision making. It presents defensible strategies for choosing and using climate-change scenarios that recognize the irreducible uncertainty of future climate and meet the challenge of developing useful climate information for decision making.
Key take-aways from the paper:
· Understanding the entire system is critical to assessing how a species will fare under changing climate
