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 Research Suggests that Urbanization & Higher Temperatures Influence Butterfly Emergence Patterns
Last edited 4/26/2016
A team of researchers focused on 20 common butterfly species in Ohio to examine the effect of temperature and urban density on butterfly emergence patterns. Results revealed a wide range of responses to urbanization across species, but one finding stood out.
“The combined effect of an urban area and a warmer part of the state appeared to delay emergence in seven of the 20 species,” Wepprich says.
The affected species in these areas emerged days or weeks after other butterflies of the same species emerged in either rural areas in the warmer parts of Ohio, or urban areas in colder parts of Ohio.
“Even though butterflies often change their emergence predictably to small increases in temperature, these species responded in unexpected ways to larger increases in temperature,” Wepprich says.
“Scientists often use analogies for global climate change, such as urban warming, to understand how species' might respond to a warmer future,” Wepprich adds. “This allows us to estimate which species are more vulnerable to climate change.
“We don't really know precisely where the tipping point is, or why only some species respond this way, but something is happening here. We're still working to better understand what's going on with these butterfly species and what consequences there may be for their populations.”
