The milkweed plants growing in 40 cube-shaped chambers on a hilltop at the University of Michigan Biological Station provide a glimpse into the future that allows researchers to ask a question: How will monarch butterflies ...
As dwindling populations of monarch butterflies prepared for their annual migration, two undergraduate students in the William & Mary Plant Ecology Lab spent their summer trying to more deeply understand the plants upon which ...
(Phys.org) —University of Arizona researchers are playing a leading role in an unprecedented effort to save America's most iconic butterfly, the monarch.
Habitat loss on breeding grounds in the United States – not on wintering grounds in Mexico – is the main cause of recent and projected population declines of migratory monarch butterflies in eastern North America, according ...
Everyone knows all about the epic breeding journey taken each year by generations of monarch butterflies between Mexico and Canada, right? Not so fast, say researchers including University of Guelph biologists.
(Phys.org) —Could there soon be a summer without the iconic monarch butterfly?
The number of Monarch butterflies making it to their winter refuge in Mexico dropped 59 percent this year, falling to the lowest level since comparable record-keeping began 20 years ago, scientists reported Wednesday.
Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of specieshappen to share, according to new research.
One of the more difficult aspects of evolution for some people to swallow is the notion that random copying errors in DNA can add up to anything useful.
Ensuring the monarch butterfly's survival by saving its milkweed habitat could result from U.S. Department of Agriculture (USDA) studies initially intended to improve detection of boll weevils with pheromone traps.
