Interstate 35 lies at the heart of a vast circulatory system, one of the massive transportation arteries that enable Americans to move long distances quickly. The highway also cuts through the heart of the eastern monarch’s central flyway, which produces the vast majority of brilliant orange and black butterflies that undertake one of the world’s most grueling insect migrations.

En route from as far away as southern Canada to their wintering grounds in steep, fir-clad slopes northwest of Mexico City, monarchs must fly through numerous metropolitan areas strung along the 1,568-mile river of asphalt, including Minneapolis-St. Paul, Kansas City, and Dallas-Fort Worth. Once a vast expanse of prairie, today the I-35 corridor not only bisects cities and suburbs but also passes through the Corn Belt, an ever-expanding patchwork of corn and soybean monocultures laced with the pesticide glyphosate. According to Chip Taylor, director of Monarch Watch and a biologist at the University of Kansas, the resulting loss of monarch habitat has been “tremendous.”

New study showed relief from current dry spell unlikely within next 10,000 years

Invasive ascidians — sac-like marine invertebrate filter feeders — are nuisance organisms that present a global threat. They contribute to biodiversity loss, ecosystem degradation and impairment of ecosystem services around the world.

A new Tel Aviv University study finds that ships play an unknowing but dominant role in introducing and dispersing these tough-shelled non-indigenous organisms into new environments. The research showed that these marine invertebrates hitch a ride on half of all the marine vessels passing through Israel's Mediterranean coast.

When Hurricane Eugene was nearing its peak, NASA analyzed the storm's heavy rainfall over the open waters of the Eastern Pacific Ocean. That rainfall has lessened as Eugene has weakened to a tropical storm on July 11.

Hurricane Eugene formed on July 7, 2017, in the eastern Pacific Ocean south of the Baja Peninsula. On July 8 at 10:36 p.m. EDT (July 9 at 0236 UTC) the Global Precipitation Measurement mission or GPM core satellite passed over the storm and measured rainfall intensity. 

To the vexation of school children and elation for their parents, residents living along the I-95 corridor of the northeastern United States know that El Niño in the Pacific will result in a dryer, warmer, and less snowy winter throughout the Appalachian, as certain as the adage ‘April showers bring May flowers.’ Such meteorological patterns where interannual variability in ocean temperatures affects climate have been long established in the field.
