Free-floating DNA to reveal the health of river and lake ecosystems

The mix of DNA floating in rivers and lakes will finally be used to monitor the state of aquatic ecosystems, after years of tests to show that the technique works. Conventionally, aquatic life is monitored by capturing organisms, either by using nets or scraping under boulders, for examination. These techniques are time-consuming, can harm species and require skilled ecologists. Monitoring fish typically involves using…

Study on Weed Killers and Monarch Butterflies Spurs Ecological Flap

Monarch butterfly populations have been declining since the 1990s, and several studies have linked this to the proliferation of crops genetically engineered to tolerate the glyphosate-based herbicide Roundup. Crops are routinely doused with it, killing all but the engineered plants—and the casualties include milkweed, on which monarchs exclusively lay their eggs. Some 850 million milkweed…

A tasty Florida butterfly turns sour

The viceroy butterfly is a mimic, modeling its orange-and-black colors after the queen butterfly, a bug that tastes so disgusting predators have learned not to eat it or anything that looks like it, including viceroys. The apparent dependence of mimics on their models made biologists wonder if the fates of the two species are forever…

Butterflies Vs. Border Wall: National Butterfly Center Seeks Restraining Order

The National Butterfly Center, in danger of losing access to most of its wildlife nature preserve along the Rio Grande, is asking a court to stop federal officials from building a border wall across its land. The North American Butterfly Association first sued more than a year ago after government officials allegedly cut down trees and cleared…
